A power supply apparatus includes a formed article having two or more separate accommodating cavities and an electrode group that comprises a rolled up laminate and is accommodated in each of the accommodating cavities, the laminate composed of a cathode and an anode, each having a current collector and mixture layers disposed on the current collector, and a separator sandwiched between the cathode and the anode. An electrolytic solution is accommodated in each of the accommodating cavities, the electrolytic solution, and the anode or the cathode contact the formed article.

A large current is required to drive a traction motor used in a hybrid car and so forth. For example, when starting or accelerating, a hybrid car requires a huge current equal to or greater than 100 A to drive the traction motor. As this power supply apparatus for supplying a large current, a power supply apparatus including secondary cells with a high energy density, has been known.
In addition, as this power supply apparatus, a power supply apparatus in which a plurality of unit cells, such as nickel-hydrogen batteries, nickel-cadmium batteries or lithium-ion batteries are connected, has been known (for example, see Patent Literatures 1 and 2).
The power supply apparatuses disclosed in Patent Literatures 1 and 2 have a plurality of connected unit cells and a holder to secure these unit cells. The material for the holder is, for example, plastic. Even if one unit cell fails, a power supply apparatus having a plurality of unit cells as described above can supply a current as long as other unit cells work.
However, in the power supply apparatuses as disclosed in Patent Literatures 1 and 2, a material having a low thermal conductivity, such as plastic, is used to fabricate a holder, the heat of unit cells generated during the operation of the power supply apparatus is less likely to be conducted to the holder. Therefore, there has been a problem that heat is accumulated in unit cells during the operation of the power supply apparatus, and therefore the temperature of the unit cells increases.
When the temperature of unit cells increases, the performance of the unit cells decreases, and therefore the performance of the overall power supply apparatus decreases. Meanwhile, if a unit cell is a lithium-ion battery, increase in temperature involves a risk of thermal runaway.
To solve this problem, a technique for enclosing a plurality of connected unit cells with a molded article made of metal such as aluminum having a high thermal conductivity (for example, see Patent Literature 3) has been known.
FIG. 1 is a perspective view showing power supply apparatus 1 disclosed in Patent Literature 3. As shown in FIG. 1, power supply apparatus 1 has molded article 10 having a plurality of unit cell accommodating cavities 11 and unit cells 20 accommodated in unit cell accommodating cavities 11. In addition, molded article 10 has coolant channel 13 that allows coolant for cooling molded article 10 to pass through. Molded article 10 is made of a material such as aluminum having a high thermal conductivity.
In this way, by enclosing unit cells 20 with molded article 10 having a high thermal conductivity, the heat of unit cells 20 generated during the operation of power supply apparatus 1 is conducted to molded article 10 and removed. Therefore, unit cells 20 are cooled to prevent the temperature of unit cells 20 from increasing. In addition, heat conducted to molded article 10 is conducted to coolant flowing through coolant channel 13 and discharged outside.
However, power supply apparatus 1 shown in FIG. 1 has a problem that unit cells 20 are not sufficiently cooled during the operation, and therefore the temperature of unit cells 20 increases. Now, referring to FIG. 2, a cause for increase in temperature of unit cells 20 during the operation of power supply apparatus 1 will be explained. FIG. 2 is an enlarged view showing region X in power supply apparatus 1 shown in FIG. 1.
In power supply apparatus 1, unit cells 20 are accommodated in unit cell accommodating cavities 11, so that the diameter of unit cell accommodating cavity 11 is set greater than the diameter of unit cell 20. Therefore, when unit cell 20 is accommodated in unit cell accommodating cavity 11, gap G occurs between unit cell 20 and the inner wall of unit cell accommodating cavity 11 as shown in FIG. 2. When gap G is formed between unit cell 20 and the inner wall of unit cell accommodating cavity 11, the air between unit cell 20 and unit cell accommodating cavity 11 serves as a heat insulator, so that the heat of unit cell 20 is not conducted to the body. Therefore, heat remains in unit cell 20 to increase the temperature of unit cell 20.
Therefore, even if the heat conductivity of the material for the molded article enclosing unit cells is made high, it is not possible to sufficiently cool the unit cells, and this causes problems of decrease in the performance of unit cells and thermal runaway.
To solve the problem like this, a power supply apparatus has been known where not unit cells, but electrode groups each composed of a cathode, an anode and a separator, and electrolytic solution are directly accommodated in a molded article (see Patent Literature 4). FIG. 3 is an exploded perspective view showing a power supply apparatus disclosed in Patent Literature 4. As shown in FIG. 3, power supply apparatus 1 has electrically conductive molded article 10 having four accommodating cavities 11 and made of aluminum and so forth, and four electrode groups 21 accommodated in accommodating cavities 11. In addition, the inside of molded article 10 is hollow to allow cooling air to pass through. Moreover, in power supply apparatus 1 shown in FIG. 3, electrode groups 21 are serially connected through side plates 31 and 33.

PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.


There is provided a nitrogen treating method capable of treating nitrogen compounds efficiently. The method is a nitrogen treating method of treating nitrogen compounds in for-treatment water by electrolysis and performs a first treating step of producing ammonia from the nitrogen compounds in the for-treatment water by electrolysis using a cathode and an anode between which a cation exchange film is interposed so as to define a cathode reaction region and an anode reaction region, and a second treating step of removing the ammonia in the for-treatment water treated in the cathode reaction region by the first treating step.

1. Field of the Invention
The present invention relates to a nitrogen treating method for water to be treated (hereinafter, "water to be treated" will be referred to as "for-treatment water") which contains organic nitrogen, nitrite nitrogen, nitrate nitrogen, nitrate ions, and ammonia.
2. Description of the Related Art
It has heretofore been well known that existence of nitrogen compounds is one of causes of eutrophication of rivers and lakes. Further, the nitrogen compounds exist in domestic waste water and industrial waste water in large amounts and are difficult to eliminate, and there are currently no effective countermeasures against removal of the nitrogen compounds. In general, a biological treatment is carried out. In the biological treatment, ammonia nitrogen contained in for-treatment water is converted into nitrate nitrogen or a nitrogen gas by denitrifying bacteria. Accordingly, the biological treatment has a problem that a treatment time is significantly long and a treatment efficiency is significantly low.
Further, there is another problem that since the denitrifying bacteria are significantly influenced by ambient temperature environment, components contained in the for-treatment water, and the like, particularly during the winter season when temperature is low, their activities are lowered, and a resultant reduction in denitrifying action causes efficiency of the treatment of the for-treatment water to be unstable.
Under such circumstances, to solve the foregoing technical problems, there is a method of converting ammonia nitrogen, nitrite nitrogen or nitrate nitrogen into a nitrogen gas through oxidation or reduction by passing an electric current through for-treatment water.
However, the conventional method of treating nitrogen compounds by electrolysis has a problem that while ammonia is produced from nitrate ions at a cathode, a reverse reaction in which nitrate ions are produced from the ammonia produced at the cathode occurs at an anode, resulting in a decrease in a treatment speed. Along with this, there exists an inconvenience caused by a reduction in efficiency of nitrogen removal.


A bearing housing for supporting a bearing of a gas turbine engine. The bearing housing comprises an annular body extending around an axis and having an oil inlet and an oil outlet. The bearing housing further comprises an oil manifold integrated into the annular body, the oil manifold having an inner oil channel defined in the annular body and extending circumferentially around the axis, the inner oil channel in fluid communication with the oil inlet and at least one oil jet directed towards the bearing.

Oil is delivered to various locations in gas turbine engines for cooling and lubricating purposes. In typical gas turbine engines, a bearing housing may include an oil manifold that is bolted, braced or otherwise mounted within the bearing housing. This oil manifold delivers oil to the bearing housed within the bearing housing and to the main engine shaft via one or more oil jets. Such typical add-on oil manifolds are often complicated to install and/or repair, offer little flexibility in terms of optimizing the placement of the oil jets, and could potentially interfere with rotating components such as the engine shaft. In addition, such add-on manifolds typically require their own complex sealing arrangements to connect to the engine's main oil supply to avoid temperature-related degradation.


A method of detecting a biological sample includes the following steps. A magnetic sensor chip is provided, wherein the magnetic sensor chip includes a substrate and a magnetic sensing layer located on the substrate. Probes are connected to the magnetic sensor chip. A sample solution containing biological samples labeled with a first marker is provided on the magnetic sensor chip, so that the biological samples labeled with the first marker are hybridized with the probes. Magnetic beads labeled with a second marker are provided on the magnetic sensor chip, so that the magnetic beads labeled with the second marker are bound onto the biological samples labeled with the first marker. A signal sensed by the magnetic sensing layer is detected by a magnetic sensor.

At present, biological samples are generally detected using traditional optical detection techniques. However, traditional optical detection techniques are not effective in optically identifying low-concentration biological samples, and are susceptible to background matrix interference during spectral identification, thus resulting in a reduced detection sensitivity. Therefore, the development of a detection technique and method not limited by optical identification is currently an important topic in this field.

An extraction process and an apparatus for separating aromatic compounds contained in a liquid hydrocarbon feedstock where the feedstock feed into the lower part of an extraction column is brought into intimate countercurrent contact therein with a third liquid and at least partially with at least one structured packing element (31) of the static mixer type contained in the upper part of the extraction column. Such third liquid (feed to the top of said column) is in the form of a solvent which is immiscible with the feedstock except for being capable of extracting the aromatic compounds. At least part of the extract phase rich in solvent and aromatic compounds is separated by liquid--liquid separation (26), preferably by gravity type decantation, into a phase rich in solvent and essentially depleted of raffinate, which is removed, and a phase rich in raffinate and impoverished in solvent, which is recycled to the extraction step. The extraction process is typically to be used to formulate lubricant oils.

The extraction process which comprises contacting the feedstock to be treated, in liquid phase, with a third, countercurrently circulating solvent, also in the liquid phase. This is a well-known industrial operation and is intended to ensure the transfer of one or more feedstock solutes to an immiscible phase, namely the third liquid solvent. This results in two phases: an extract phase (solvent and solute) and a raffinate phase (feedstock freed of a major part of solute).
Such a process is used, in particular, to eliminate the aromatic compounds present in feedstocks used to formulate lubricant oils. This is because said oils must show only minor variations in viscosity with temperature, and the aromatic compounds show highly variable viscosity. Moreover, the aromatic compounds are sensitive to oxidation and can cause coke formation by polycondensation.
In general, the solvent and the feedstock to be treated are made to circulate countercurrently in an extraction column. The solvent which is heavier than the feedstock is introduced at the upper part, and the feedstock at the lower part, of the column. A raffinate phase, impoverished in aromatic compounds stemming from the original feedstock, and small quantities of solvent are collected at the top, and an extract phase containing a major part of the solvent and the dissolved aromatic compounds stemming from the original feedstock is collected at the bottom of the column.

A shoe pocket for storing articles such as keys, change, etc. when engaging in athletic activities. The shoe-pocket has a pocket section with an open end formed with front and back sides. A flexible loop is attached to the back side for passing between a shoe and its laces and close the open end of the pocket. There is also a removable fastening material secured to the back side which removably fastens to the laces to prevent movement of the shoe pocket when jogging and engaging in other activities.

The present invention relates to a shoe-pocket that attaches to the laces of a shoe, and in particular to a shoe-pocket which attaches to the laces by one or more positive engagement systems for quick attachment and detachment.
There is a greater emphasis on athletics today compared to the past generations. An exercise shared by men and women is jogging which requires a minimum of clothing, such as a shirt or jacket, a pair of pants, and athletic shoes. Because of a lack of pockets, joggers are often hard pressed to carry door keys, change or other items which may be needed. Various shoe pockets have been employed to meet these needs. For example, U.S. Pat. Nos. 4,280,287, 4,372,060, 4,507,882, 4,630,383 and 5,094,016 generally describe product devices which are carried on athletic shoes, however, they all suffer from one or more disadvantages.
With the proliferation of the aids virus in today's civilization and the increasing public awareness of the need for the use of a condom in sexual activities, it is imperative that a condom be readily available when needed. Thus, this invention readily lends itself to this situation, as the condom will be available regardless of the presence or absence of pockets or pouches in the jogger's running outfits.
The shoe-pocket shown in U.S. Pat. No. 4,280,287 is attached to an athletic shoe. The shoe pocket is sewn to the shoe on three sides, leaving one side open to receive an object. There is a hook and loop system to close the open side, thereby retaining the object. In another embodiment, a flat sheet with either the hooks or loops of a hook and loop system sewn to the perimeter is removably attached to the other of the hooks or loops permanently attached to the shoe to mate with the hooks or loops of the flat sheet. The problem with either of these embodiments is that the shoe pocket is located on the side of the shoe which may be difficult to reach or the shoe pocket may catch on something that may open the pocket and releasing the object contained therein.
Another shoe pocket permanently attached to an athletic shoe is disclosed in U.S. Pat. No. 4,372,060 where the pocket is integral with the tongue. The tongue has an extra long length with a depression for holding articles. The extra length is folded over covering the articles. A hook and loop system holds the extra length in the folded position to close the depression or pocket. There is a problem with the folded extra length and the depression since the articles may slip out when jogging. Another problem is that the end of the tongue is also held down by the shoe lace, therefore the lace must be untied to uncover the pocket.
U.S. Pat. No. 4,507,882 shows a shoe-pocket attached to the laces of an athletic shoe at one end of the pocket. The problem with this arrangement is that it is attached only at one end of the shoe pocket flaps during running or walking, which creates a distraction.
The shoe-pocket in U.S. Pat. No. 4,630,383 is integrally formed as an extension of the shoe tongue. The tongue folds over the laces with the pocket opening exposed. A loop and hook system is employed to close the pocket. The shoe-pocket is only attached to the shoe tongue, therefore it is free to flap.
An interesting shoe-pocket is shown in U.S. Pat. No. 5,094,016 where the shoe-pocket is attached to the athletic shoe by the shoe laces. There is a loop and hook system for closing the open end of the pocket. Once the shoe-pocket is laced to the shoe it can not be removed without unlacing the shoe.


A method of using capacitance-sensitive touchpad, wherein the touchpad includes a plurality of zones on a surface thereof, wherein detection of a finger within one of the plurality of zones determines a direction and a speed of scrolling within a window in a graphical user interface, and wherein detection of a finger within one of the plurality of zones determines a direction and a speed of movement of a cursor performing edge motion in the graphical user interface, thus making edge motion and scrolling dependent only upon a detected location of a finger within the plurality of zones, and not dependent upon detecting movement of the finger.

1. Field of the Invention
This invention relates generally to touchpads. More specifically, the present invention is a method for creating a plurality of discrete zones or regions in a border region of a touchpad, wherein a scrolling zone and edge motion are both controlled by finger location, not finger motion, wherein placing a finger in specific zones is used to control speed of scrolling within a graphical window, and the angle of automatic edge motion of a cursor in a graphical user interface.
2. Description of Related Art
To understand the advantages and differences of the present invention as compared to the prior art, this document first examines the prior art of edge motion and of scrolling.
Beginning with edge motion, in U.S. Pat. No. 5,327,161, Logan teaches a touchpad having a form of edge motion. FIG. 1 is a diagram that illustrates the main concept of the patent. A finger moves along the surface of the touchpad 10 along the line indicated as 12, thereby controlling movement of a cursor on a graphical user interface. When the finger reaches a border region 14, the touchpad determines a direction of movement (indicated as dotted line 16) of the finger as it entered the border region. The user can stop movement of the finger in the border region 14, and the cursor will continue movement in the direction 16 determined by the touchpad 10 when the finger first entered the border region until the user removes the finger from the surface of the touchpad, or moves the finger out of the border region.
In U.S. Pat. No. 5,880,590, Gillespie et al. teaches a modification of the Logan method. Specifically, a fixed reference point 22 is established on the touchpad 20 as shown in FIG. 2. When the user moves a finger across the surface (as indicated by solid line 24) of the touchpad 20 and enters a border region 24, a vector is determined by the touchpad. However, instead of determining the vector relative to the direction of movement of the finger as it enters the border region as in Logan and indicated by dotted line 26, the vector is taken from the fixed reference point 22 and the location 28 where the finger enters the border region 24. In this example, the direction of movement of the cursor would thus be in the direction indicated by dotted line 30. It can be seen that while different from Logan, the direction of continued movement of the cursor is relatively more difficult for a user to determine until movement of the cursor actually begins because continued movement is no longer determined by the last known direction of movement of the finger. Thus, the '590 patent does not use the more intuitive direction of continued cursor movement as taught by Logan.
In U.S. Pat. No. 5,880,411, also issued to Gillespie et al., the '411 patent teaches still another method that is different from the Logan method and the method of the '590 patent. Specifically, the '411 patent teaches that a finger on a surface of a touchpad 40 enters a border region 42 as shown in FIG. 3. However, instead of determining any vector, a cursor will simply move in a direction that is orthogonal to the edge of the touchpad 40 as indicated by dotted line 44. In other words, the cursor in this example would move in a horizontal direction straight toward the right edge of a graphical display because the finger entered a right border region 42 of the touchpad 40. This method is known as orthogonal edge motion.
The '411 patent also teaches being able to modify the movement of the cursor. Consider the example of FIG. 4 where the cursor is moving in the direction indicated by dotted line 44 of FIG. 3. If the user's finger moves first in the direction indicated by arrow 48 in a vertical direction, the horizontal movement of the cursor continues, but now has added to it a vertical component that follows the motion of the user's finger. This horizontal and vertical movement is indicated as upwardly sloping segment 52 of the cursor movement. If the finger momentarily stops, the cursor movement levels out as indicated by level segment 54 of the cursor movement. When the finger moves in the direction and magnitude of arrow 50, the cursor movement follows downward sloping segment 56. The cursor movement follows level segment 58 when the finger stops vertical movement.
Some helpful observations about how the border regions operate in the '161, the '590, and the '411 patents are as follows. The '411 patent teaches that regardless of what vector the finger has when entering the border region, the cursor moves orthogonally relative to the border region that has bee entered. There is no other option but to move orthogonally. In addition, the '411 patent teaches that vertical movements of the cursor are controlled by determining a previous position of the finger in the border region, and a present position. This realization is important to understanding the differences between the prior art and the present invention.
FIG. 5 illustrates the concept that if the finger is at a first position 60 and moves to a second position 62 in a border region 64, corresponding movement of the cursor on the graphical display will be a vertical component of movement in the same direction. Critically, when the finger stops, the cursor will eliminate any vertical component of movement, but continue its horizontal movement. In other words, the vertical cursor movement is directly dependent upon movement in the vertical direction within the border region 64. This is because the '411 patent teaches that motion is the determining factor for adding a vertical component of cursor movement. In other words, the actual position or location of the finger in the border region is only important in being able to determine that movement is taking place. Accordingly, as long as movement is detected, cursor movement is modified.
The discussion above is focused on the issue of edge motion. In other words, edge motion addresses the issue of how cursor movement is modified when a finger enters a border region. In contrast, the following discussion is centered on the concept of scrolling. For the purposes of this patent, scrolling is defined as controlling horizontal or vertical movement within a window on a graphical user interface by receiving signals from a touchpad.
Scrolling is another element that exists in the prior art of touchpads. In U.S. Pat. No. 5,943,052 issued to Allen, the Allen patent teaches a scrolling region 70 on touchpad 68 as shown in FIG. 6. Vertical movement 72 within the scrolling region 70 results in scrolling within a graphical user window in a graphical user interface shown on a display screen. What is important to observe is that Allen teaches that a data packet processor generates messages in response to "object motion." Object motion is apparently not dependent upon the location or position of a finger in the scrolling region 70. Instead, object motion is again dependent upon simply determining that motion is taking place, and then causing corresponding vertical (or horizontal) movement of the contents of the window.
It is important to understand the implications of this limitation of Allen. First, if movement of the finger causes scrolling action to occur, terminating movement of the finger likewise requires that scrolling must stop. Second, scrolling is not location dependent. In other words, scrolling action is not determined by where the finger is located within the scrolling region, it is only dependent upon whether or not the finger is moving, and in which direction the finger is moving.

A device for clustering light spots, the device is configured to receive an image captured by a camera, detect light spots in the image, calculate a distance measure for each of a plurality of pairs of light spots detected in the image, and group the detected light spots to clusters based on the calculated distance measures.

A task of camera based Advanced Driver Assistance Systems (ADAS) applications, e.g., advanced headlight control, is to detect headlights and tail lights of other vehicles at night in order to switch on and off high beam in car or trucks automatically. The control of the high beam depends on whether other vehicles are detected ahead or not.
The traffic ahead of the vehicle is caught by a camera. The images captured by the camera are analyzed in order to detect headlights and tail lights of other vehicles. For complexity reduction and better performance, lights can be grouped together to pairs or clusters, e.g., all lights of one car or lights of a group of cars can be grouped together.
In current state of the art technology handpicked rules are used for the pairing and/or clustering of headlights and tail lights in image data. However, those rules may not be optimal. In addition, these rules are not flexible.

Device and a method for clustering light spots


A system is provided for assuring the straightness of pipes or tubes produced by a continuous seam-welded process. Following sizing, the newly formed continuous tube passes through a straightening unit and a preliminary alignment checker. The alignment checker observes the actual spatial position of the advancing tube, and the straightening unit is adjusted in response to deviations of the observed position from the predetermined desired path to deform the tube so that it conforms to the desired path. The advancing continuous tube is then severed into individual tube sections of desired length, and some or all of the sections are inspected for straightness. In inspecting for straightness the individual sections are rotated about their longitudinal axes to place the seam-weld in a predetermined position for correlating the angular attitude of the section with that of the advancing continuous tube. Deflection of the midregion of the individual tube relative to the ends is observed along orthogonal axes, and the straightening unit is adjusted in response to the magnitude and direction of observed deviation of the tube from straightness. The straightener appropriately deforms the advancing continuous tube to minimize curvature in subsequent individual sections. Inspected sections falling outside acceptable standards for straightness may be provided with an identifying indicia.

1. Field of the Invention
The present invention relates generally to the manufacture of continuous seam-welded metal tubes or pipes, and more particularly to a system for observing the axial alignment of the pipe or tube as it is fabricated and continuously correcting the alignment in response to observed deviations so as to produce tubes having a high degree of axial alignment or straightness.
2. Description of the Prior Art
In accordance with a well-known procedure for fabricating seam-welded pipes and tubes, a continuous strip or skelp is advanced through a forming apparatus and progressively deformed into a tubular form having an open, longitudinally extending seam. The tubular form then advances through a welding station wherein the adjacent longitudinal free edges are urged together and joined by a suitable welding process. The particular process to be employed will generally be dictated by, among other factors, the material from which the tube or pipe is formed. For example, the pipe may be formed of low carbon steel, stainless steel, aluminum, etc., and the welding process may include any of the well-known welding techniques conventionally employed with the various materials. In a widely used embodiment the tube or pipe is heated by electrical induction so that the edges achieve fusion temperature, and the heated edges are urged into engagement to produce a continuous monolithic welded seam.
Following the welding step, the pipe or tube may advance through a scarfing unit for removal of the raised bead created incident to the formation of the welded seam, and then through a series of sizing rolls for imparting the precise diameter and cross-sectional configuration to the formed pipe. Finally, after the continuous pipe has been sized and cooled, it enters a cut-off mechanism wherein it is cut into sections of appropriate length.
Due, among other factors, to residual stresses in the material following formation of the pipe, and the heating and cooling incident to the welding of the seam, the pipe may tend to warp or snake and develop an undesirable non-linear configuration as it exits the constraints of the forming and welding mechanism. In order to minimize the amount of this curvature in the finished product, the pipe or tubing is directed through a straightening unit wherein appropriate forces are applied by straightening rolls to bend the pipe to compensate for existing curvature and cause it to assume a linear profile as it exits the forming apparatus. Heretofore, the pipe has been observed at some distance downstream from the straightening unit by an operator to visually determine the amount and orientation of existing curvature, and the straightening unit then manually adjusted in response to the observed condition to compensate for the curvature. The procedure functions well for its intended purpose, and permits production of pipe of good quality. However, it has not been found entirely satisfactory in that it is dependent upon the operator's visual observation and subsequent manual adjustment of the straightening unit. It is thus subject to the operator's judgment, as well as human error. In addition, deviation of the pipe is best observed at some distance downstream from the straightening unit, typically in the cut-off area. Since the pipe advances at a relatively rapid rate, a significant amount of defective pipe may be produced between the time at which deviation is noted and corrective action can be taken at the straightening unit.


Apparatuses, methods, and systems for closing open loops of a wireless mesh network are disclosed. One method includes determining a representation of a wireless mesh network including nodes, and wireless links between the nodes, identifying end-site nodes of the wireless mesh network, determining open loops of the wireless mesh network that include the identified end-site nodes, generating a list of potential nodes for closing each of the open loops with the identified end-site node, testing one or more of the potential nodes, comprising testing performance of a wireless connection between each end-site node and the one or more potential nodes, wherein the performance includes a number of wireless hops around each closed loop formed including the end-site node and each potential node, selecting a closing node based on the testing, and providing a wireless link connection between one or more of the end-site nodes and the closing node.

Planning of wireless network is a critical phase that occurs prior to deployment, especially for wireless backhaul networks. A key requirement of the network planning includes high redundancy or network availability of the backhaul network. A typical network planning results in a network that includes end sites that need to be manually closed to improve redundancy. This requires manual intervention and thereby slows down the network design process.
It is desirable to have methods, apparatuses, and systems for closing open loops of wireless mesh networks.

1. Technical Field
The present invention relates to an installation device for an instrumentation device which inhibits transmission of vibration to the instrumentation device to be mounted to the engine frame of a stationary engine, and enables prevention of faults and malfunctions of the instrumentation device.
2. Description of the Related Art
When instrumentation devices such as a sensor and an amplifier are directly fixed to an engine frame, the vibration of the engine is transmitted to the instrumentation devices, which causes faults and malfunctions of the instrumentation devices. For this reason, when the instrumentation device is mounted to the engine frame, vibration isolating measures are required. Conventionally, there has been used, for example, a vibration isolating device as shown in FIG. 7.
FIG. 7 shows an engine frame 102 of a stationary gas engine 100. The stationary gas engine 100 is provided with four cylinder heads 104. A cylinder internal pressure sensor 108 for detecting the combustion pressure in the cylinder is mounted for each cylinder head 104. A lead wire 110 is connected between the cylinder internal pressure sensor 108 and a combustion diagnosis device 114. The combustion pressure in the cylinder is transmitted to the combustion diagnosis device 114 by the lead wire 110. The diagnosis information by the combustion diagnosis device 114 is sent to a main controller 116 for controlling the operation of the stationary gas engine 100. An amplifier 112 is inserted at the midpoint of the lead wire 110.
On a plane 106 formed at the engine frame 102, an instrumentation device installation device 120 having a vibration isolating function is disposed for every cylinder. The instrumentation device installation device 120 includes a base 122 fixed to the plane 106, four wires 124 connected at respective one ends thereof to the four corners of the base 122, and a vibration isolating stage 126 to which the other ends of the wires 124 are connected. A fixing band 128 is bonded to the top surface of the vibration isolating stage 126. The amplifier 112 is held by the fixing band 128, and is fixed to the vibration isolating stage 126.
The vibration isolating stage 126 is supported in a floating sate in the air by the bending elastic force of the wires 124. Thus, by holding the amplifier 112 in a floating sate in the air, the vibration of the engine frame 102 is prevented from being transmitted to the amplifier 112. However, unfavorably, the instrumentation device installation device 120 has a complicated structure, and requires a space for installation thereof, and is expensive.
In Patent Document 1, there is disclosed a vibration isolating mechanism in which a fuel pressure (fuel pressure detection) sensor for detecting the pressure in the high pressure fuel path is mounted to the cylinder body via a vibration isolating material in an intra-cylinder fuel injecting type engine. The vibration isolating mechanism is configured as follows: the fuel pressure sensor is not in direct contact with the cylinder body; a gap is caused between the fuel pressure sensor and the cylinder body; and the fuel pressure sensor is fixed to the cylinder body via the vibration isolating material.
Patent Document 1: Japanese Patent Application Laid-open No. 2001-65386
The vibration isolating mechanism disclosed in Patent Document 1 is configured as follows: although the fuel pressure sensor is not directly fixed to the cylinder body, its own weight of the fuel pressure sensor is imposed on the cylinder body via the vibration isolating material. Accordingly, to the fuel pressure sensor, the vibration of the cylinder body becomes more likely to be transmitted through the vibration material. This imposes a given limit on the vibration isolating effect.
The stationary engine is mounted and fixed to a stationary stand. Accordingly, the vibration of the engine frame includes mostly only the vibration transmitted from the engine. For this reason, the vibrations of the engine frame are the vibrations including limited vibration frequencies. The vibrations having different vibration frequencies do not cancel each other. Thus, the vibration including a single frequency tends to be amplified. Further, when the vibration frequencies of the fuel pressure sensor and the vibration isolating material disclosed in Patent Document 1 are within a resonance generation region with the vibration frequency of the engine, the resonance phenomenon occurs, and a large vibration is caused in the fuel pressure sensor. This may cause faults or malfunction of the fuel pressure sensor.
In view of the foregoing circumstances, the present inventors conducted a study on measures for improving the vibration isolating effect of the instrumentation device installation device set in the engine frame of the stationary engine. FIG. 8 shows a vibration isolating device for a stationary gas engine (unpublished) as the intermediate technology invented before the present inventors reach the present invention.
In FIG. 8, the vibration isolating device 130 is formed of a fixing stand 132 including flange parts 132a and 132e formed by bending a plate made of one sheet of metal or hard resin, and being in contact with the plane 106 formed at the engine frame 102, sidewall parts 132b and 132d bent at right angles to the flange parts, and vertically arranged in a direction away from the plane 106, and a fixing part 132c disposed between the sidewall parts.
The flange parts 132a and 132e are bonded to the plane 106 by bolts 136. A fixing band 138 is bonded to the top surface of the fixing part 132c, and the amplifier 112 is held by the fixing band 138, and is fixed to the fixing part 132c. A vibration isolating rubber plate 140 is interposed between the fixing band 138 and the amplifier 112. The lead wire 110 establishes connections among the cylinder internal pressure sensor 108, the amplifier 112, and a combustion diagnosis device (not shown).
In such a vibration isolating device 130, the vibration of the engine frame 102 is attenuated by the vibration isolating rubber plate 140. However, the vibration transmitted from the engine frame 102 through the fixing stand 132 to the amplifier 112 is not eliminated. For this reason, as with the vibration isolating mechanism disclosed in Patent Document 1, a given limit is imposed on the vibration isolating effect.

Installation device for instrumentation device of stationary engine


Disclosed is a retardation film which shows a high light selective absorbency to visible rays having short wavelengths near 400 nm to have a high light resistance, and which can give, when used in a display device, good display properties to the display device. This film is a retardation film, satisfying all of the following formulae (1) to (4): 2≤A(380) (1), 0.5≤A(400) (2), 0.4≥A(420)/A(400) (3), and 100 nm≤Re(550)≤170 nm (4), in which each A(λ) represents the absorbance of the film at a wavelength λ nm, and Re (550) represents the in-plane retardation value of the film to a light ray having a wavelength of 550 nm.

Field of the Invention
The present invention relates to a retardation film, a circularly polarizing plate including the retardation film, and a display device including the retardation film.
Description of the Related Art
In a flat panel display device (FPD) such as an organic EL display device or a liquid crystal display device, various members are used, examples thereof including display elements such as an organic EL element and a liquid crystal cell, and optical films such as a polarizing plate and a retardation film. An organic EL compound, a liquid crystal compound and other materials that are used for these members are organic substances. Thus, a problem may be caused that these materials are deteriorated by ultraviolet rays (UV). In order to solve such a problem, various countermeasures have been made.
For example, according to Patent Literature 1 (JP-A-2006-308936), such members are prevented from being deteriorated by adding an UV absorbent into a protection film for polarizing plates used in these display devices. Moreover, in an actual situation that display devices are desired to be made thinner, a polarizing plate without having any protection film has been required. Patent Literature 2 (JP-A-2015-143789) discloses an attempt for producing a retardation film from a polymerizable liquid crystal compound having a UV absorbing function to express both of the UV absorbing function and a retardation function.


A crimper includes a first arm that includes a first crimper die that defines a first tapered channel. The crimper also includes a second arm coupled to the first arm at a pivot connection. The second arm includes a second crimper die that defines a second tapered channel. The pivot connection enables the first arm and the second arm to rotate about the pivot connection from an open state to a closed state. The first arm and second arm rotate at an angle relative to one another to allow loading of the expandable medical device into the first tapered channel or the second tapered channel and to allow positioning of the expandable medical device relative to a delivery device. When transitioning, the first tapered channel and the second tapered channel form a chamber that is configured to crimp the expandable medical device from the uncompressed state to the compressed state.

Currently, implantable medical devices and appliances, such as large stents, scaffolds, and other cardiac intervention devices that contain organic tissue, e.g., bovine and porcine, require onsite crimping onto a delivery device or appliance. This is due to the need to store the implantable devices in conditions specific to preserve the organic tissue. Typically, aftermarket iris style crimpers are utilized in the crimping processes. These iris style crimpers require a workstation that may be unwieldy and cost prohibitive due to their single use nature. Additionally, multiple crimping steps are sometimes necessary, and placement of the device in relation to marker bands or retaining features is difficult, which may require expensive, customized crimping equipment. Also, due to the complexity of the iris style crimping devices, sterilization of these single use devices may be difficult.

Portable and hand-held medical device crimper


Building panels, such as a floor or wall panels. The panels include a first mechanical locking system include a first locking strip at one of the third edge or fourth edge configured to cooperate for horizontal locking with a first locking groove at the other of the third or fourth edge of an adjacent building panel, preferably by means of a folding motion, and a second locking system including a second locking strip at one of the first edge or second edge, configured to cooperate for horizontal locking with a second locking groove at the other of the first or second edge of an adjacent building panel. The thickness of the second locking strip, in a thickness-direction of the building panel, exceeds the thickness of the first locking strip.

Laminate flooring usually comprise a core of a 6-12 mm fibre board, a 0.2-0.8 mm thick upper decorative surface layer of laminate and a 0.1-0.6 mm thick lower balancing layer of laminate, plastic, paper or like material. A laminate surface comprises melamine-impregnated paper. The most common core material is fibreboard with high density and good stability usually called HDF—High Density Fibreboard. Sometimes also MDF—Medium Density Fibreboard—is used as core.
Laminate floor panels of this type have been joined mechanically by means of so-called mechanical locking systems. These systems comprise locking means, which lock the panels horizontally and vertically. The mechanical locking systems are usually formed by machining of the core of the panel. Alternatively, parts of the locking system may be formed of a separate material, for instance aluminium or HDF, which are integrated with the floor panel, i.e., joined with the floor panel in connection with the manufacture thereof.
The main advantages of floating floors with mechanical locking systems are that they are easy to install. They may also easily be taken up again and used once more at a different location. However, know systems suffer from drawbacks, for example in respect of water-tightness. As such, there is room for improvements in the technical field.

1. Field of the Invention
The present invention relates to a digital-broadcasting receiving apparatus and a digital-broadcasting receiving method.
2. Description of Related Art
A digital-broadcasting wave includes a broadcast data of a physical channel assigned to each frequency band area, and the broadcast data of each physical channel includes a broadcast data of plural sub-channels. In order to allow the broadcast data of the physical channel assigned to the limited frequency band area to include the broadcast data of plural sub-channels, a video data, an audio data, etc., which are included in the broadcast data of the physical channel are coded and multiplexed by the MPEG2 (Moving Picture Experts Group Phase2)-TS (Transport Stream) system. Therefore, in order to view the broadcast data of each sub-channel, in the digital broadcasting receiving apparatus which receives a digital-broadcasting airwave, it is necessary to recognize and register individually beforehand the sub-channel included in the digital-broadcasting wave. Then, the technique to scan and register the broadcast data of the sub-channel included in the digital-broadcasting wave has been developed (e.g. JP2002-101353A).
The sub-channel includes a free sub-channel and a pay sub-channel. A video data, a audio data, etc. of the pay sub-channel are usually coded (hereinafter referred to as "scrambled") so that only the person who paid a charge can view it. In some cases, the non-scrambled broadcast data of the sub-channel and the scrambled broadcast data of the sub-channel are mixed in the broadcast data of the physical channel. In this case, when all the broadcast data of the sub-channels included in the digital-broadcasting wave are scanned and registered, non-scrambled sub-channels which are not viewable are also registered.
The technique to judge, by referring to a tsc (transport scrambling control) bit included in a header region of the broadcast data of the sub-channel which is coded and multiplexed by the MPEG2-TS system included in the broadcast wave, whether the broadcast data of the sub-channel is scrambled or not is known (JPHei11-220655A).
However, actually, because the tsc bit does not often reflect whether the broadcast data is scrambled or not, there is the case that it cannot be exactly judged whether it is scrambled or not by referring the tsc bit. It is possible, by actually decoding the video data and judging whether it can be decoded or not, to judge exactly whether it is scrambled or not. However, because it takes time to decode the scrambled video data, it is not realistic to scan all frequency bands area including the broadcast data of all sub-channels while examining whether they can be decoded or not.

1. Field of the Invention
The present invention relates to an electronic apparatus represented by a personal computer for example.
2. Description of the Related Art
In recent years, personal computers (hereinafter sometimes referred to as "PC") have been in widespread use not only in offices but also at homes. As one type of personal computers, there have been widely known notebook personal computers (hereinafter referred to as "notebook PC") each composed of: a main unit having a keyboard on the top surface; and a display unit openable and closable with respect to the main unit and having a display screen. The display unit is opened to stand relative to the main unit when in use and is folded to lie on the keyboard when not in use.
Also, plate-like tablet personal computers (hereinafter referred to as "tablet PC") having a display screen on the top surface have emerged in recent years. A user enters an instruction into this type of PC by bringing a stylus closer to a position on the display screen or touching the position with the stylus so as to make the tablet PC recognize the position.
Also, another type of electronic apparatus capable of operating both as a notebook PC and a tablet PC have come along recently. This type of apparatus has a main unit and a display unit which are connected via a two-axis connection section that supports the main unit and the display unit in such a manner that they can be opened/closed and rotated.
General electronic apparatus such as personal computers are desired to be smaller in size. Particularly, the above-mentioned notebook PCs, tablet PCs and the like are desired to be smaller and thinner because they need to be portable. Lately, as the notebook PCs have become more and more multifunctional, performance of notebook PCs has almost reached the high level comparable to that of desktop PCs. Therefore, it is desired to realize a smaller and thinner apparatus that also maintains high operability while keeping with the trend toward multifunction. Not only notebook PCs but also various types of devices, such as game machines, DVD recorders and players, hard-disk recorders are desired to be smaller and thinner for the purpose of saving space of an installation site.
The above types of electronic apparatus often need a component extending through an opening formed in a cabinet between the inside and outside of the cabinet. For example, as for a notebook PC where a display unit needs to be attached to a main unit via a hinge mechanism such that the display unit can be opened and closed, a component constituting such a hinge mechanism is often fixed inside the cabinet of either one of the main unit and the display unit and extends to the other one of these units through the outside of the cabinet so that it is fixed therein.
Amid the trend toward size reduction of apparatus, a number of components and units have to be packed in tight space inside the cabinet. This raises a problem of the affixing structure of such a component extending to the outside of the cabinet forming an apparatus.
Japanese Patent Application Publication No. 2000-47754 proposes a component that extends between the inside and outside of a cabinet and has a portion entering the inside of the cabinet and having wings both spreading along an inner wall of the cabinet. This component is fixed from the outside of the cabinet by screws and the heads of the screws are exposed to the outside, which impairs the design. If the portion of the component entering the inside of the cabinet is screw-fixed inside the cabinet in order to avoid such exposure, it is necessary to form space for accommodating a fixing portion for fixing the component inside the cabinet. However, such space is difficult to form when there is no room near an opening through which the component extends between the inside and outside of the cabinet.
In view of the foregoing, the present invention provides an electronic apparatus whose structure for affixing a component extending between the inside and outside of the cabinet through an opening of the cabinet has been devised, and also provides an assembly to be employed in such an electronic apparatus.


A turbine nozzle includes a hollow vane joined to opposite inner and outer bands. The inner band includes a forward lip under the leading edge of the vane, an aft lip under the trailing edge of the vane, and a mounting flange spaced therebetween. An impingement bore extends obliquely and aft from the base of the mounting flange under a corner of the inner band toward the aft lip for impingement cooling thereof.

The present invention relates generally to gas turbine engines, and, more specifically, to turbine nozzles therein.
In a gas turbine engine air is pressurized in a compressor and mixed with fuel in a combustor for generating hot combustion gases. Energy is extracted from the hot gases in several turbine stages following the combustor for powering the compressor and an additional output shaft for turbofan aircraft engines, or marine and industrial engine applications.
The turbine stages include stationary turbine nozzles which direct the combustion gases into corresponding rows of turbine rotor blades extending radially outwardly from the perimeter of supporting rotor disks. The first stage turbine nozzle is disposed at the outlet of the combustor and includes a row of hollow vanes supported in radially inner and outer bands.
The hot gases discharged from the combustor effect substantial thermal loads in the turbine nozzle, and cause substantial thermal expansion and contraction thereof during the operating cycle of the engine. In order to reduce thermal stresses in the nozzle, the nozzle is typically segmented circumferentially in vane doublets including two vanes mounted in corresponding inner and outer band segments. The segments have end faces or axial splitlines in which spline seals are used to connect the row of doublets in a complete annular assembly.
The spline seals seal the end faces of the nozzle segments from the hot combustion gases flowing through the turbine flowpath, as well as from the cooling air being circulated outside the outer band and inside the inner band for cooling thereof. And, the outer and inner bands adjoin the outlet end of the combustor on the forward side thereof, and adjoin the inlet end of the first stage turbine rotor blades on the aft side of the nozzle, with suitable seals therebetween.
The individual nozzle vanes include internal cooling circuits or cavities through which cooling air bled from the compressor is circulated for providing internal cooling of the nozzle vanes during operation. And, the nozzle vanes typically include various rows of film cooling holes extending through the pressure and suction sidewalls thereof for discharging the spent internal cooling air in corresponding films of air along the external surface of the vanes for providing thermal insulation from the hot combustion gases flowing thereover during operation.
The individual nozzle vanes have aerodynamic profiles, with the pressure side being generally concave and the opposite suction side being generally convex between the leading edge of the vane to the relatively thin trailing edge of the vane. The velocity and pressure distributions of the combustion gases correspondingly vary over the opposite sides of each vane for maximizing performance of the turbine in extracting energy from the combustion gases to power and rotate the turbine blades supported on the rotor disk.
In one exemplary gas turbine engine, experience has uncovered oxidation damage to the inner band of the first stage turbine nozzle which limits its useful life. The damage is localized to one corner of the inner band at the aft end thereof along the suction side of the nozzle vane. This oxidation may be due to hot gas ingestion between the inner band end faces at the aft end of the splitline due to random variations in differential pressure between the hot combustion gases on the turbine flowpath side of the inner band, and the cooling air provided on the opposite cooling side of the inner band.
Accordingly, it is desired to provide a turbine nozzle having improved cooling of the inner band to address this local oxidation problem and increase the useful life of the turbine nozzle.


The present claims recite various steganographic and digital watermarking methods and apparatus. One claim recites a method of watermarking a representation of a physical object. The method includes: projecting a watermark orientation component onto a physical object; and using a camera or image sensor, capturing an image or video of the physical object including the watermark orientation component as projected thereon. Another claim recites an apparatus including: a light source for projecting a registration component onto a physical object; a camera or sensor for capturing an image or video of the physical object including the registration component as projected thereon; and an electronic processor programmed for encoding a message in the image or video captured by said camera or sensor. Of course, other claims and combinations are provided as well.

Digital watermarking technology, a form of steganography, encompasses a great variety of techniques by which plural bits of digital data are hidden in some other object, preferably without leaving human-apparent evidence of alteration.
Digital watermarking may be used to modify media content to embed a machine-readable code into the media content. The media may be modified such that the embedded code is imperceptible or nearly imperceptible to the user, yet may be detected through an automated detection process.
There are many processes by which media can be processed to encode a digital watermark. In physical objects, the data may be encoded in the form of surface texturing or printing. Such marking can be detected from optical scan data, e.g., from a scanner or web cam. In electronic objects (e.g., digital audio or imagery—including video), the data may be encoded as slight variations in sample values. Or, if the object is represented in a so-called orthogonal domain (also termed "non-perceptual," e.g., MPEG, DCT, wavelet, etc.), the data may be encoded as slight variations in quantization values or levels. The assignee's U.S. Pat. Nos. 6,122,403 and 6,614,914 are illustrative of certain watermarking technologies.
Digital watermarking systems typically have two primary components: an embedding component that embeds a watermark in the media content, and a reading component that detects and reads the embedded watermark. The embedding component embeds a watermark pattern by altering data samples of the media content. The reading component analyzes content to detect whether a watermark pattern is present. In applications where the watermark encodes information, the reading component extracts this information from the detected watermark.
One problem that arises in many watermarking applications is that of object corruption. If the object is reproduced, or distorted, in some manner such that the content presented for watermark decoding is not identical to the object as originally watermarked, then the decoding process may be unable to recognize and decode the watermark. To deal with such problems, the watermark can convey a reference signal or "orientation component." The orientation component is of such a character as to permit its detection even in the presence of relatively severe distortion. Once found, the attributes of the distorted reference signal can be used to quantify the content's distortion. Watermark decoding can then proceed—informed by information about the particular distortion present.
The Assignee's U.S. Pat. Nos. 6,614,914 and 6,408,082 detail orientation components, and processing methods, that permit such watermark decoding even in the presence of distortion.
To provide a comprehensive disclosure without unduly lengthening this specification, each of the U.S. patent documents cited in this specification are hereby incorporated by reference.
With the foregoing by way of background, the specification next turns to various digital watermarking improvements. It will be recognized that these improvements can typically be employed in many applications, and in various combinations with the subject matter of the patent documents cited herein. These improvements will be more readily apparent from the following detailed description, which proceeds with reference to the accompanying drawings.

Field of Invention
Various exemplary embodiments relate generally to an electronic device, and more particularly, to a semiconductor device including plurality of processors and a method of operating the same.
Description of Related Art
In portable electronic devices such as portable multimedia players, mobile phones, smart phones, GPS navigation devices, digital cameras, digital video cameras, personal digital assistants, etc., a multi-processor system which employs a plurality of processors in a single system to perform various functions in a smooth manner and perform each function at a high speed is preferred. Since each processor can control at least one function block within a system, the function blocks within the system can operate more effectively in accordance with control of two or more processors.
A mobile phone, for example, may be implemented to have, in addition to its basic phone functions, music player functions, video player functions, communication functions with wireless Internet, payment functions, game functions, camera functions, etc. Thus, there is a need to employ both a communications processor for performing communication modulation and demodulation functions and a processor for performing functions other than the communication functions in a mobile phone. Furthermore, a plurality of processors can be employed in a controller for a storage medium within the system. The plurality of processors employed as such enable the controllers to work at high speeds.

Semiconductor device including a plurality of processors and a method of operating the same


A firearm suppressor configured for coupling to a firearm with its stock barrel bushing removed. The firearm suppressor includes a barrel bushing feature, a recess, and a release. The barrel bushing feature duplicates the barrel bushing of the firearm, which constrains the movement of the barrel of the firearm. The recess is positioned below the barrel bushing and is configured to receive and retain a cap of a recoil spring plug of the firearm. The firearm suppressor is coupled to the firearm when the cap of the recoil plug of the firearm is retained in the recess. The release is configured to press against the recoil spring plug of the firearm. Actuating the release pushes the recoil spring plug of the firearm away from the firearm suppressor, such that the firearm suppressor is removable from the firearm in the same manner as the original barrel bushing.

Conventional firearm suppressors are muzzle-mounted devices that reduce sound intensity when the firearm is discharged. Suppressors may be detachably coupled to, or an integral part of, the barrel of the firearm. Detachable suppressors may be equipped with "female" threads on the end of the suppressor for engaging with matching threads on the barrel of the firearm. However, most firearms don't come with threaded barrels for attaching muzzle-mounted accessories. Therefore, conventional suppressors require any firearm to be retrofitted with a threaded barrel.


A pair of magnetic recording parts are axially spaced on a rotating shaft and a pair of magnetic heads for recording and reproducing a location signal are respectively opposed to the respective magnetic recording parts. Torque of the rotating shaft is calculated based on a quantity of a phase shift of the location signals reproduced by the respective magnetic heads and rotating speed of the rotating shaft is calculated based on a reproducing frequency of the location signal reproduced by one of the magnetic heads so that the magnetic recording parts and the magnetic heads serves as a sensor for detecting both torque and rotating speed. Thus, a number of parts of the sensor is lessened, being compacted with low cost.

This invention relates to a torque and rotating speed sensor for detecting both torque of a rotating shaft and rotating speed (rpm) of the rotating shaft.
In an automatic transmission in a car employing an torque converter, speed change, line pressure, and the like have been controlled according to an rpm (a number of rotation) of an engine or throttle valve opening. In addition, it is known that with the line pressure control according to the torque of a turbine shaft the automatic transmission effectively displays a feature.
Also a known technique is that a magnetic sensor is used for directly detecting the torque of a rotating shaft such as the turbine shaft. In the sensor, a pair of magnetic recording parts respectively to which a location signal in a circumferential direction of the rotating shaft is to be recorded are provided on the rotating shaft, being axially spaced, and a pair of magnetic heads for recording and reproducing the location signal are respectively opposed to the respective magnetic recording parts. A quantity of torsion of the rotating shaft is measured based on a phase shift of the location signals to be reproduced by each magnetic head so as to obtain the torque according to the torsion quantity (refer to Japanese Patent Publication Gazette No55-34369).
Accordingly, it may devised that the automatic transmission perfoms controls based on the torque of the turbine shaft detected by the magnetic sensor. While, in the automatic transmission control, in addition to the torque of the turbine shaft, rpm of an engine is required to separately detect for speed change control and torque-down control. The rpm of the engine can be obtained according to the detected rpm of the turbine shaft.
In such the case where torque and rotating speed are detected only from the single rotating shaft, however, each sensor for detecting each is required. Further, a space for arranging each signal detecting means for the sensors is required on the rotating shaft, which leads to an oversized, heavy, expensive automatic transmission. As to detection of the rpm, in a method of detecting the rpm from a frequency by writing an optical mark circumferentially on a surface of the rotating shaft and scanning the mark, a frequency for writing the optical mark cannot be made high, which means no improvement in detecting an accurate rpm.
An object of the present invention is to provide a torque and rotating speed sensor for simply, accurately detecting both torque and rpm without increases in size and weight and with low cost.
Another object of the present invention is to provide a torque and rotating speed sensor for simply, accurately detecting the rotating speed at any time of high and low rpm of the rotating shaft.
Another object of the present invention is to provide a torque and rotating speed sensor for accurately detecting torque and rpm of the turbine shaft in an automatic transmission.
Further object of the present invention is to realize an ideal line pressure control in the automatic transmission.


A method for measuring acoustic impulse response of a Device Under Test (DUT) addresses sample rate variations by determining clock rate differences between the DUT and test system, and making adjustments to compensate for the different clock rates. An interrogation signal is generated with two “events” spaced a known number of samples apart, at the nominal sampling rate of the DUT. The interrogation signal is played through the DUT and recorded by a measurement system. The number of samples between the two “events” is measured in the sampled signal to determine the shift introduced by the different clock rates. The adjustment is then applied to either the original frequency response measurement signal by adjusting the sampling rate of a frequency response measurement signal to compensate for the different clock rates, or to the measured signal before averaging, to align the samples and prevent cancelling.

The present invention relates measuring the impulse response of a system, and in particular, reducing errors when averaging multiple repetitions to smooth the impulse response measurement of phone systems.
Known methods have difficulty in measuring the frequency response of a Device Under Test (DUT), for example a phone, clocked separately from a measurement system. Although the clocks of the phone and the measuring device may vary by as little as 0.001%, methods averaging multiple measurements for noise reduction may fail. For example, when measuring the frequency response of a DUT that is playing back at 48 kHz, with a test system that is recording at 48 kHz, the two sampling rates will differ from each other by a very small amount, due to the relative precision of their individual oscillators. When measuring acoustic signals, averaging multiple repetitions of a frequency response measurement signal is performed in the digital domain to reduce the measured and uncorrelated noise. When the sampling rates differ even slightly, each repetition of the frequency response measurement signal becomes more and more out of phase with the DUT signal, until cancellation and comb filtering arise.
Measurements might be performed using a single measurement iteration, but no noise reduction would result.

Method for asynchronous impulse response measurement between separately clocked systems


The present invention relates to a method for performing in-process compensating a machining operation on a workpiece, wherein the compensation process includes generating a control signal representative of magnitude of a contact force exerted on a cutting tool in a normal direction in relation to a machining surface of the workpiece, determining a compensation parameter value based on the control signal, and compensating the machining operation based on the compensation parameter value. The present invention also relates to corresponding machine arrangement for performing a machining operation on a workpiece, such as a hard turning process.

Various high performance and high quality metal, steel, or ceramic components, such as bearing components, rods, axles, shafts, couplings, engine members, etc., may be manufactured from a workpiece using a turning process. The turning process involves a machining operation which physically removes material from a machining surface of the workpiece with a cutting tool, often comprised of a replaceable tool insert or tip, such as a carbide, CBN, or ceramic insert. Material removal during the machining operation is achieved by providing a relative rotational movement between the workpiece and the cutting tool, contacting a machining surface of the workpiece with a tip of the cutting tool, and moving the cutting tool in relation to the workpiece such that a suitable amount of material is removed during each revolution of the turning process.
In order to achieve proper high quality properties of the components, such as high dimensional accuracy, such as roundness and cylindricity which are critical factors, further treatment involving e.g. grinding and/or honing manufacturing steps are commonly utilized. Additional manufacturing steps, however, require additional machinery and increase manufacturing time and complexity as well as cost. Hence, in order to facilitate the manufacturing, it is desired to improve the quality of the final cut of the components from the machining operation such that subsequent manufacturing steps for achieving the intended dimension and surface finishing of the component may be reduced, or avoided. In particular, this applies to hard turning manufacturing wherein the machining operation is performed on a component workpiece which has the hardness required by the final component application, such as a rolling bearing application in the case of a bearing ring or rolling body component.
Machining operations, however, involve highly complex interactions between the cutting tool and machining surface of the workpiece, which, during the manufacturing process, impede the accuracy and properties of the finalized component. For example, initial workpiece distortions, e.g. from hardening processes, as well as an initial high level of surface roughness and dimensional inaccuracy of the machining surface to be processed, have a negative effect on the machining results. Furthermore, essentially stochastic, and/or uncontrollable, turning processes relating to the cutting tool, such as chipping, fracturing, wear, build-up edge, etc., affect the final cut by e.g. increasing the profile error of the machined component. This leads to that the final quality and performance of the component is compromised, and that manufacturing productivity is hampered.
Hence, there exists a need to improve current techniques and to achieve manufacturing processes and machining equipment capable of providing improved and more efficient machining operations, higher productivity and improved components with increased dimensional accuracy and surface properties.

Single container wind resistant modular ISO building


Setting parameter values are migrated through a new software upgrade. Each software version includes a version number. The version number of the new software is compared to a version number of the current software. The version number of the current software is determined by reading a version number parameter value stored in a non-volatile random access memory (NVRAM). If the version number of the new software is higher than the version number of the current software, for each setting parameter value within a new map file, either a current setting parameter value stored in the NVRAM or a default value from the map file, is loaded into a temporary memory. The map file, corresponding to the current version number parameter value stored in the NVRAM, is used to associate the values in the NVRAM to their corresponding setting parameters. Once a value for each setting parameter is loaded into the temporary memory, the values from the temporary memory are then loaded into the NVRAM.

When current versions of many of today's applications software or operating software are upgraded, existing user settings are lost during the upgrade process. User settings in place prior to the software upgrade are replaced by default settings associated with setting parameters of the new software version.
Set-top boxes are often used as intermediary devices between a content source such as a personal computer or a remote cable television provider, and a display device such as a television. Often, set-top boxes allow users to adjust control settings such as tint, brightness and color, using an operating software within the set-top box. The adjusted control settings can subsequently be saved within a system memory of the set-top box. When the control software for the set-top box is upgraded, new control setting parameters with associated default settings are typically included within the new upgraded software. These new control setting parameters and associated default values replace the previous control setting parameters and any user adjusted values associated with them.

A nanowire system includes a substrate and at least one nanowire structure which extends out along an axis from a surface of the substrate. The nanowire structure comprises a light emitting diode and a device driver electrically coupled to control an operational state of the light emitting diode. The light emitting diode and the device driver are integrated to each share at least one doped region.

Current display resolution is reaching its practical limitations. To enable advances in pixel density and resolution the Thin-Film Transistors (TFTs) included in displays must be further reduced in size.
Accordingly, the future of display technology may be with nanowire light emitting diodes (LED) which are being pursued due to higher efficiencies (70% vs. 5-7%), higher reliability, and the potential to provide higher pixel densities. With respect to reliability, nanowire LEDs when compared against other currently available technologies are better able to withstand long term operation and higher temperatures because of the material the nanowire LEDs can be made from. However, with respect to higher pixel densities, there has been no easy way to densely integrate nanowire LEDs with transistors (switches) that turn them "on" or "off". Currently available approaches to address this issue sacrifice LED area along as well as device performance thus limiting potential applications.
In particular, previous works on combining transistors with LEDs have relied on approaches that degrade LED performance, consume area, and increase cost. These approaches include methods such as, dedicating an area for the lateral growth of another material to create a High Electron Mobility Transistor (HEMT). Unfortunately, this process leads to reduced LED performance and takes up an undesirable portion of the total device area.
Another approach has tried growth on silicon which is combined with CMOS transistors. Unfortunately, growth on silicon can create defects in the LEDs due to the mismatch of material, which correspondingly degrades performance. Additionally, this approach still struggles with managing temperature variations and still consumes too much area.
Yet another approach has tried flip-chip bonding with LEDs on silicon. With this approach, LEDs are separately fabricated, individually cut out, and then mounted on top of a silicon wafer to combine the LEDs with CMOS transistors on silicon. Unfortunately, this approach has reliability concerns from the hundreds of separate LEDs that need to be connected together, along with the inability to shrink in size past existing technology.

Diffractive optical elements are used in methods and devices for coupling or distributing electromagnetic radiation. The diffractive optical. elements may be adapted to split one or more streams of radiation into multiple streams of radiation or to combine multiple streams of radiation to produce single streams. A plurality of diffractive optical elements may be fabricated on substrates by lithographic or molding methods. Diffractive optical elements that split one or more streams of radiation can be combined with diffractive optical elements that combine multiple streams of radiation to provide a coupling device, for example, a star coupler. The star coupler may be used in networked optical communication systems to provide multiple coupling between a plurality of optical drivers and a plurality of optical receivers. Aspects can be applied to any type of electromagnetic radiation having a wavelength that can be used as a medium for transferring information.

For the purpose of chip-to-chip, board-to-board, and system-to-system communications over high bandwidth distance links, the use of optical interconnection networks as replacements for their electrical counterparts is steadily growing. For links of high bit rate and distance (for example, greater than 10 meter-gigabits per second), optical transmission technology is increasingly providing better cost and performance versus electrical transmission technology. An additional advantage of optical transmission technology is that it can provide multi-point links without significant reduction in performance.
Multi-drop and multi-point links are particularly useful in computer and communications systems with many integrated processing units, such as for Symmetric Multi-processor (SMP) buses, memory buses, and I/O buses in high-end systems, since such links allow close coupling between multiple different devices without multiple separate point-to-point links. For example, the "broadcast-and-snoop" protocols used for assuring coherence between processor caches could be most effectively implemented over a parallel bus of many multi-point links, if they could be made to operate at sufficiently high bit rate. High frequency electrical signaling limitations limit practical operation of multi-point links to a bit rate of roughly 500 Megabits/sec, which is increasingly insufficient for modem computer systems, so implementation of the broadcast functionality is typically implemented with a cascaded network of point-to-point links, greatly increasing system cost, complexity, and power consumption.
In the prior art, the optical equivalent for the multi-point link is an "optical star coupler". In an optical star coupler, optical data streams from each of the inputs are combined in the star coupler and physically distributed to all of the outputs, so that each input can (with appropriate arbitration for access) broadcast data to all of the outputs. These optical star coupler networks are created through the careful integration of devices that perform functions such as beam-splitting, "fan-in", "fan-out", and coupling. Optical star couplers are common components in the area of optical interconnection networks for transmitting each of multiple input signals to all of multiple destinations, thus connecting each of N inputs to all of N outputs simultaneously, N is an integer greater than zero.
Prior art star couplers are characterized by numerous disadvantages that make prior art star couplers unsatisfactory for use in computer broadcast bus interconnection networks. For example, prior art star couplers exhibit limited efficiency in coupling the input and output waveguides; exhibit limited efficiency in distributing input power from the input to the output waveguides; are not readily scalable for more complex applications; and are limited to a single-plane geometry. Most particularly, prior art star couplers do not allow integrated construction of multiple independent star coupler functions for multiple independent sets of links, as is required for multi-link computer bus interconnection networks.

The present invention provides a solid composition comprising the following ingredients (A) and (B):                (A) wheat albumin, and        (B) a C6 to C12 sugar alcohol,wherein a content mass ratio of the ingredient (B) to the ingredient (A), (B)/(A), is 0.2 or higher.

In recent years, a considerably increased number of patients suffer glucose metabolism disorders including obesity and Type II diabetes (hyperglycemia), mainly due to a change in dietary habits.
Generally, blood glucose level elevates after a meal, particularly after ingestion of a meal containing carbohydrate, and insulin is secreted by pancreatic β cells. Insulin acts on muscle, liver, adipose tissue, and the like and promotes the intake of sugar into cells, whereby an acute increase in blood glucose level after a meal is suppressed. However, when the postprandial blood glucose level remains high due to impaired insulin sensitivity (i.e., insulin resistance), the pancreas secrets a large amount of insulin so as to suppress an increase in blood glucose. If such a state continues for a long period of time, the pancreas is exhausted, to thereby decrease insulin secretion by pancreatic β cells. Eventually, the insulin action mechanism does not normally function, which triggers Type II diabetes or the like.
Postprandial hyperglycemia caused by insulin resistance is also observed in non-diabetes healthy people and borderline diabetes patients. In addition, postprandial hyperglycemia is known to cause obesity, hyperlipidemia, arteriosclerosis, etc. as well as Type II diabetes, and to serve as an exacerbation factor therefor. Therefore, prevention of postprandial hyperglycemia is very important from the viewpoints of health maintenance, lowering the risk for onset of these symptoms and disorders, and prevention thereof.
Under such circumstances, in recent years, there have been developed a number of substances that can suppress an acute increase in postprandial blood glucose and insulin secretion. Some of these substances are amylase inhibitors, and a wheat-originating amylase inhibitor is employed for prevention and treatment of diabetes, obesity, etc. (Non-Patent Document 1).
The endosperm of wheat contains about 10 to about 15% protein, and albumin (water-soluble protein) occupies about 11% of the protein composition. It has been reported that albumin has α-amylase inhibitory activity and physiological functions such as postprandial blood glucose increase inhibitory action and insulin resistance improving action (Non-Patent Documents 1 and 2). Above all, a wheat albumin having an electrophoretic mobility of 0.19 exhibits high α-amylase inhibitory activity, and therefore application thereof to various foods is expected.
In order to obtain physiological functions of wheat albumin, a single injection of the wheat albumin having an electrophoretic mobility of 0.19 (hereinafter may be referred also to as "0.19 wheat albumin") in an amount of 125 mg or more per single diet is believed effective (Non-Patent Document 2). Hitherto, as commercial health foods containing an effective amount of wheat albumin, soup and hard capsules are available on the market. Also, Patent Document 1 discloses a tablet containing 0.19 wheat albumin.
