Back of a motor vehicle with a rear hatch, a rear hatch opening and a device for moving the rear hatch of a motor vehicle between a closed position and an intermediate position. The device has positioning means by which the rear hatch can be moved solely by linear translation between the intermediate position and the closed position. In the intermediate position, the opening edge and the rear hatch edge as a whole have an essentially constant distance from one another. For closing the rear hatch from the open position, the rear hatch is pivoted out of the open position into the intermediate position, and afterwards, linear displacement of the rear hatch out of the intermediate position into the closed position is performed, the linear displacement taking place over a path from 1 cm to 5 cm.

To prevent this, various anti-pinching systems have been developed. They work either with sensors, such as, for example, with infrared or ultrasonic sensors or mechanical contacts, or in the case of motor-controlled devices for moving the rear hatch, with time-dependent or event-dependent control of the motor current.

A packaged die includes a substrate having an upper surface and a micro device on the upper surface and an encapsulation cover comprising one or more grooves on its lower surface. The lower surface of the encapsulation cover and the upper surface of the substrate are bonded together to form a plurality of air-tight closed-loop interfaces and encapsulate the micro device.

The present disclosure relates to the packaging of micro devices.
Assuring reliability and yield are two critical tasks for the manufacturing of micro devices, such as integrated circuits and micro electro-mechanical structures. Typically, in manufacturing micro devices, multiple micro devices are fabricated on a semiconductor wafer. The semiconductor wafer is then separated into individual dies containing individual micro devices. The electrical and optical performance of the micro devices are often tested for quality assurance on the individual dies in an ambient environment. For testing purposes, electrical and optical signals need to be properly input into the circuits in the micro device on the each die. Output electric and optical signals from the micro devices need to be properly detected and measured to analyze the functional performance of the micro devices on the dies. During testing and handling of the micro devices, the micro devices must not be contaminated by dust and pollutants in the ambient environment. Electrical and optical input and output, as well as protecting the micro devices from the environment, all need to be considered when designing packaging for the micro devices. Given the increased complexity of the micro devices and the testing requirements, a need exists for improved die packaging for the micro devices.


The present invention provides a running control device for an industrial vehicle which generates no speed change shock when the traveling direction is switched to the opposite direction by the forward-reverse selection member during the running of the vehicle. The running control device comprises a forward-reverse selected direction detection sensor which detects the selected traveling direction, a transmission which has a forward clutch and a reverse clutch that switch the traveling direction between the forward direction and reverse direction, and which transmits the driving torque of the engine to the driving wheels via the clutches, a brake which applies braking to the vehicle, a vehicle speed sensor which detects the vehicle speed, and a controller which gradually decelerates the vehicle by means of the brake when the selected traveling direction that has been detected is switched, and controls the engaging force of the forward or reverse clutch corresponding to the selected traveling direction and the braking force of the brake before the detected vehicle speed reaches zero, thus controlling the deceleration torque and acceleration torque so that the fluctuation in the acceleration around the point of time at which the traveling direction is reversed is weakened.

The present invention relates to a running control device for an industrial vehicle such as a forklift or the like.
2. Description of the Related Art
In order to improve driving operability and perform work with good efficiency, vehicles equipped with a torque converter and a transmission having clutches used for switching between forward and reverse and for speed stage changes are widely used as industrial vehicles such as forklifts and the like. In the case of such industrial vehicles, an operation in which the forward-reverse lever is switched from the current traveling direction of the vehicle to the opposite direction is frequently performed during the running of the vehicle; in this case, it is necessary to ensure that the vehicle can run smoothly without any shock during forward-reverse changeover.
For example, a technique which is devised so that when the forward-reverse operating lever is switched over, operating oil is supplied to the braking device so that the vehicle is decelerated until the vehicle is reversed to the traveling direction selected by the forward-reverse operating lever, and the brakes are then let off after the traveling direction has been reversed, has been proposed as one conventional control method technique for solving this problem (e.g., see Japanese Patent Application Laid-Open No. 2002-79926 (pages 5–6, FIGS. 3–4). According to this patent application, when, for example, the forward-reverse operating lever is switched from the "forward position" to the "reverse position", braking is applied by the braking force of the brake corresponding to the vehicle speed so that the vehicle is caused to decelerate; then, when the traveling direction is switched to the reverse direction after the vehicle stops, and the vehicle begins to travel in the reverse direction, the "forward travel" signal in the brake control circuit is switched "off", so that a specified relay is switched "off". As a result, the control oil is cut off, so that the brake is released.
However, when the abovementioned conventional technique disclosed in Japanese Patent Application Laid-Open No. 2002-79926 is used, although the braking force is actuated in accordance with the vehicle speed, this braking force is actuated until the vehicle speed reaches zero, and when the brake is subsequently let off, there is an operating delay time until the brake is completely released; accordingly, with the vehicle speed of zero as a boundary, the braking torque acts in the opposite direction from the vehicle acceleration torque. In other words, for a speed change without any shock, it is necessary that the fluctuation in the acceleration and deceleration of the vehicle itself during the speed change be small; however, in the abovementioned technique, since the braking torque constantly acts as a braking torque, the acceleration of the vehicle itself is caused to fluctuate greatly by the effect of this braking torque when the traveling direction of the vehicle is reversed. Consequently, the following problem arises: namely, a speed change shock is generated in the vicinity of a vehicle speed of zero, so that a smooth speed change operation cannot be accomplished. Furthermore, since the driving force of the hydraulic clutch is forcibly suppressed by the brake after the traveling direction is reversed, the following problem arises: namely, not only is there an energy loss, but also a drop in the durability of the brake and hydraulic clutch.

An electronic apparatus and an electronic system may include a first power delivery network (PDN) and a second PDN. The first PDN may include a first inductor as a segment of a power rail of the first PDN, while the second PDN may include a second inductor as a segment of a power rail of the second PDN. The first inductor and the second inductor may form a magnetically coupled inductor. The magnetically coupled inductor may provide migrated impedance ZT to the first PDN induced by the magnetically coupled inductor. The migrated impedance ZT to the first PDN may help the first PDN to reduce its voltage noise. Other embodiments may be described and/or claimed.

The background description provided herein is for the purpose of generally presenting the context of the disclosure. Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.
An integrated circuit (IC), often called a silicon chip, a computer chip, an IC chip, or a chip, may be a piece of silicon or another semiconductor into which an electronic circuit is etched using photographic techniques or other techniques. ICs may be produced in batches on a wafer. A wafer may be cut ("diced") into multiple dies. An IC, e.g., a die or a wafer, may be placed within a package. A package may be an interface between an IC and a printed circuit board (PCB). An electronic system or a computing device may be formed by electrically connecting various ICs included in packages that are assembled on a PCB, where the PCB may provide mechanical support to the electronic system.
A power distribution network (PDN) may deliver the power and the ground voltages through conductive power rails to ICs in an electronic system assembled on a PCB. A PDN may have static voltage noise and transient voltage noise. An excessive voltage noise of a PDN, e.g., a transient voltage noise, may reduce switching speeds and noise margins of ICs supplied by the PDN, which may lead to functional failures of the ICs. To reduce the voltage noise of a PDN, a conventional solution may add sufficient capacitance for each of the power rails of the PDN at all levels, e.g., on-die, in-package, and on-board of the PCB. Such a solution may use additional capacitors to achieve desired performance for the PDN, and hence may be very expensive. For example, the die size may be increased by including on-die capacitors, while the package form factor may be increased to allocate in-package capacitors for the PDN.

The invention presented relates to wireless handsfree head worn headset computing devices including a microdisplay device and spatially diverse antenna system. The spatially diverse antenna system provides an effective headset computing device radiation pattern that enables arbitrary user movement and promotes freedom of mobility. Disclosed is a headset computing device including a head worn frame having a profile relatively low in height with respect to a user's head, the user's head creating a RF shadow region along the headset profile by blocking line-of-sight RF propagation paths, the headset includes two or more antennas integrated with the headset frame to sufficiently maintained its low profile. Each antenna has a radiation pattern and are collectively arranged to form an omnidirectional radiation pattern, where at least a first radiation pattern provides coverage in the line-of-sight propagation path while the at least second radiation antenna pattern is in the RF shadow region.

Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. Most common wireless communication technologies, such as radio, use electromagnetic waves typically in the radio frequency (RF) ranges. Information, such as sound, video, or other data, is transmitted by systematically modulating at least some property of a RF carrier. Modulation techniques are well known and in general include modulating the amplitude, frequency, or phase of the RF carrier.
Wireless communication is generally achieved through the following process. A source generates a message that when represented in an electrical waveform is referred to as a baseband signal. A transmitter modulates the baseband signal for efficient transmission, which also typically includes amplification. The modulated amplified signal is fed to a transmit antenna. The transmit antenna converts the modulated signal from a signal propagating along a transmission line into a signal propagating through free space. At the destination, a receive antenna converts the signal propagating through free space into a signal propagating on a transmission line. The transmission line feeds a receiver that typically amplifies and demodulates the received signal to recover the baseband signal.
The prominence of wireless data communications technologies, such as Wi-Fi®, WiMAX® and cellular data services, including 3G (W-CDMA, EDGE, CDMA2000®, etc.), and 4G LTE, continues to increase as consumers continue to adopt and rely on mobile computing platforms, such as laptop, smart phone and tablet computing devices.

Antennas are necessary components in wireless communication systems. Generally, antennas are reciprocal devices that are classified by their electrical characteristics. As a reciprocal device, an antenna's electrical characteristics are the same for both transmission and reception. Example antenna characteristics include resonant frequency, bandwidth, gain, radiation pattern, and polarization. Such antenna characteristics are important to antenna designers and play an important part in the operation of a wireless communication system. The vast majority of antennas are based on the half wavelength dipole antenna.
An antenna radiates efficiently at its resonant frequency. Typically, an antenna element also radiates at odd multiples of a quarter wavelength of its fundamental resonant frequency, although not as efficiently as at its fundamental resonant frequency. In general, antenna efficiency and antenna size are directly related.
An antenna has a purely resistive impedance at its fundamental frequency, but most antenna applications require using an antenna over a range of frequencies. The bandwidth of an antenna specifies the range of frequencies over which its performance does not suffer due to poor impedance match. In general, antenna bandwidth and antenna size are directly related.
Gain is a parameter which measures the degree of directivity of an antenna's radiation pattern. More specifically, the antenna gain (sometimes referred to as power gain) is defined as the ratio of the intensity (power per unit surface) radiated by the antenna in the direction of its maximum output, divided by the intensity radiated at the same distance by a hypothetical isotropic antenna. The gain of an antenna is a passive phenomenon; power is not added by the antenna, but simply redistributed to provide more radiated power in a certain direction than would be transmitted by an isotropic antenna.
The radiation pattern of an antenna is a plot of the relative field strength, or gain of the electromagnetic wave emitted by the antenna at different angles. It is typically represented by a three dimensional graph, or polar plots in the three principal planes (e.g., XY, YZ and XZ) or simply in horizontal and vertical planes.
An isotropic radiator is typically defined as "a hypothetical lossless antenna having equal radiation in all directions." The isotropic antenna (or isotropic radiator) is an ideal theoretical antenna. It is considered to be a point in space with no dimensions and no mass. Although the isotropic radiator is a theoretical antenna and does not physically exist, it is often used as a reference for expressing the directive properties of actual antennas. The pattern of an ideal isotropic antenna, which radiates equally in all directions, would look like a sphere.
A directional antenna is one "having the property of radiating or receiving electromagnetic waves more effectively in some directions than in others." The term "directional" is usually applied to an antenna whose maximum directivity is significantly greater than that of a half-wave dipole.
Many antennas, such as monopoles and dipoles, have a directional radiation pattern that is non-directional in one plane (typically the azimuth plane) and directional in an orthogonal plane (typically the elevation plane). Since such antennas emit equal power in all directions in one plane (e.g., the azimuth or horizontal plane), the plot of the radiation pattern in that plane (azimuth) approximates a circle. However, such antennas are directional in the orthogonal plane (e.g., the elevation plane or vertical plane). As a result, a three dimensional plot of the radiation pattern of such an antenna is a torus or donut-shaped. This type of pattern—an essentially nondirectional pattern in one plane (typically, azimuth) and directional pattern in any orthogonal plane (typically, elevation)—is typically designated as "omnidirectional." An omnidirectional pattern is then a special type of directional pattern.
Omnidirectional antennas are only weakly directional antennas and are typically used when the relative position of the other communication station is unknown, arbitrary, or changes often. Also, omnidirectional antennas are typically used at lower frequency where a directional antenna would be too large and too expensive or where a directional antenna is simply not required. One example of an omnidirectional antenna is the vertical antenna or whip antenna, often but not always a quarter wavelength long. A dipole antenna is similar but consists of two quarter wavelength conductors extending in opposite directions, with a total length that is roughly a half a wavelength long at the resonant frequency of the device.
Directional or beam antennas, which radiate more power in a particular direction, are used when additional gain or the directionality of the antenna's beam being known is useful. Directional antennas include parabolic reflectors, horn radiators and Yagi-Uda antennas.
The polarization of an antenna is the orientation of the electric field (E-field) of the electromagnetic wave with respect to the Earth's surface and is determined by the physical structure and orientation of the antenna. For example, a dipole antenna has a linear polarization; when mounted vertically it has a vertical polarization, and when mounted horizontally it has a horizontal polarization. The reflection of electromagnetic waves off of terrestrial objects generally affects polarization.
Polarization is the sum of the orientation of the E-field vector over a period of time projected onto an imaginary plane perpendicular to the direction of travel of the electromagnetic wave. Polarization is in general elliptical, meaning that the polarization of the electromagnetic wave varies in an elliptical direction over time. There are two special cases of elliptical polarization, namely linear polarization—where the ellipse collapses into a line—and circular polarization—where the two axes of the ellipse are equal. Linear polarization is usually created by an antenna forcing the electric field of the emitted electromagnetic wave in a particular orientation. Usually linear polarizations are either vertical polarization or horizontal polarization.
It is important that polarized antennas be matched so that the maximum amount of power can be transferred between the transmitter and receiver. Therefore, vertically polarized transmit antennas should be matched with vertically polarized receiving antennas and horizontally polarized transmit antenna should be matched with horizontally polarized receiving antennas.

A method for storing information may include determining whether a received data object fits inside a particular one of a plurality of free blocks in a memory bitmap. Each of the plurality of free blocks may include a column of the memory bitmap with a top margin, a bottom margin, and a predetermined width. If the received data object fits, the received data object may be stored in the particular one of the plurality of free blocks, starting at the margin of the particular one of the plurality of free blocks. The particular one of the plurality of data blocks may be resized by moving the margin to start below or next to the stored received data object. The determining may include, for each of the plurality of free blocks, a height of the received data object may be compared with a height of each of the free data blocks.

Text, or any other graphic structure, is often drawn into a bitmap or texture, and then copied from there into the drawing destination as needed. This caching mechanism is commonly used in many different applications for a variety of data objects, including icons, images and text characters, known as glyphs.
However, conventional caching techniques for such data objects are inefficient since objects are stored sequentially and without any consideration of individual object size. Such inefficient caching results in using more memory to store more bitmaps to hold all of the necessary drawing objects, as well as using more CPU resources and memory bandwidth to copy larger bitmaps around. For example, bitmaps used on the graphics processing unit (GPU) need to be uploaded to the GPU as textures. Therefore, the larger the textures are, the longer the upload will takes and the more system resources will subsequently be used to copy the bitmaps.
Additional drawback of conventional caching techniques is that fewer drawing objects stored per bitmap results in the cache filling up quickly, which often times necessitates frequent flushing of the cache to make room for other drawing objects that cannot fit. Such frequent cache flushing reduces the utility of the on-chip memory since the system is essentially drawing objects from scratch whenever they are needed, instead of being able to simply copy the cached version of the objects.
Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such approaches with some aspects of the present method and apparatus set forth in the remainder of this disclosure with reference to the drawings.


A processor-based method, system and apparatus to comprise a method, system and apparatus to access a memory location in an on-chip memory based on a virtual processing element identification associated with an instruction. The system comprises multiple virtual processing elements, an access list and a comparator coupled to the memory and the access list. In response to an instruction from a virtual processing element to access a memory location in the memory, the comparator compares a first virtual processing identification associated with the instruction to a second virtual processing identification stored in the access list and grants access to the virtual processing element that generated the instruction to read from or write to the memory location if the first virtual processing element identification is equal to the second virtual processing element identification. The data in the memory is allocated and de-allocated by software.

Sharing memory between processors, virtual processing elements or thread contexts conventionally requires coordination between the sharing entities to avoid corruption of memory. This usually requires additional overheard in terms of signaling as in test and set locks or a memory coherency scheme. Furthermore, in the event that the sharing entities are unaware of each other, memory may be corrupted due to inadvertent overwriting of another entity's data. There is also a need for security against malicious software running one or more processors/virtual processing elements.
What are needed are new memory security measures that overcome the deficiencies noted above.

Virtual processor based security for on-chip memory, and applications thereof


A pallet container having a thin-walled rigid plastics material inner container, a tubular lattice frame of horizontal and vertical tubular bars as a supporting jacket, and a base pallet on which the plastics-material inner container bears and to which the tubular lattice frame is fixedly connected. The base pallet is configured as a frame pallet having corner feet and central feet and a clearance in the corner feet and the central feet is provided on the base. The clearance is configured such that when stacking two pallet containers the uppermost encircling horizontal tubular bar of the tubular lattice frame of a pallet container stacked therebelow engages or “nests” in a mutually adapted and form-fitting manner in the clearance. a secure transportation of two stacked pallet containers, a deeper clearance is formed such that it is deeper in the vertical direction than in the horizontal or radial direction.

Pallet containers of this type, used particularly frequently in the chemical industry, having a filling volume of approx. 1000 liters have standardized dimensions. The pallet containers discussed here have a length of approx. 1200 mm, a width of approx. 1000 mm, and a height of approx. 1151 mm, and in the filled state may only be transported as a two-tier stack (one IBC on the bottom and one IBC stacked thereon). For long distance transportation by rail or truck or overseas by ship closed 20 foot or 40 foot ISO containers are typically used. Said ISO containers (for example, Maersk) likewise have standardized dimensions (20 foot container: length approx. 6058 mm, width approx. 2500 mm, height approx. 2591 mm; the 40″ container being exactly double the length, with all other dimensions remaining the same) and are loaded and unloaded by way of a rear door. For the loading of ISO containers, this applying likewise to both sizes (Hapag Lloyd), the width of approx. 2343 mm, on the one hand, and in particular the height of approx. 2292 mm, on the other hand, of the door opening is of great importance. Unfortunately, a two-tier stack of filled pallet containers in the standard embodiment results in a stack height of approx. 2290 mm that has to be taken into account. The purely mathematical double height of two pallet containers would be 2×1151 mm=2302 mm. The lower value of approx. 2290 mm is the result of the pallet container stacked on top, due to its encircling base steel tubing on the base by way of a small measure of 15.5 mm within the uppermost horizontal encircling tubular bar of the tubular lattice frame plunging or "nesting" into said tubular lattice frame until the corner feet and central feet that externally project beyond the base steel tubing come to bear from above onto the uppermost horizontally encircling tubular bar. The uppermost horizontally encircling tubular bar of the tubular lattice frame herein engages on the external side past the base steel tubing into a head space that is configured there, or into a clearance on the lower external periphery of the corner feet and central feet, respectively, such that a safeguard against the pallet container stacked on top from shifting due to this transportation vibrations is provided on account thereof.
Tight limits are predefined in terms of the construction of the design type of the IBCs, wherein the "approximate values" for the length measurement in the present dimension are all to include a range of plus/minus 2 mm. The usual nesting depth is approx. 15.5 mm; the actual height of a stack of two IBCs would thus be (2×1151−15.5)=approx. 2286.5 mm. By virtue of the tolerances of in each case plus/minus 2 mm, the stack height to be taken into account for safety reasons is considered to be 2290 mm.
A similar pallet container having a timber pallet is described as an "intermediate bulk container of low height" in the publication EP 1 375 382 B2 (vL). The lowermost encircling horizontal tubular ring of the tubular lattice frame herein is not simply placed, like the plastics-material inner container, on top of the upper plank base as usual, but circumferentially encompasses the plank base and sits on a lower-lying encircling external shoulder, on the one hand. On the other hand, it is proposed that the drive-in height of the lateral rectangular pallet clearances for the engagement of the forks of a fork lift truck are reduced by way of a lower height of the corner feet and central feet. This in both cases results in a reduction in the overall height of the individual pallet container. This is disadvantageous in as much as pallet containers as standardized containers having predefined dimensions only represent one link in the logistics chain of the chemical industry. Any deviations from standard dimensions can lead to significant disruptions in the production process of chemical mass products such that the customers of large chemical industries no longer demand such containers. Pallet containers having a reduced overall height can lead to disruptions, for example, in the case of fully automatic filling systems, and pallet containers having a reduced drive-in height can in this instance only be handled using fork lifting gear having relatively thin prongs. Pallet containers of this type can in this instance no longer be picked up and transported by standardized lifting trucks on rollers.
