Various embodiments of the invention may provide one or more non-volatile storage entities, such as a register or a storage array, to store configuration information for a memory device. The specified configuration may then be enabled at the occurrence of a specified event, such as power-up and/or reset.

Some memory devices, such as flash memory devices, may operate in a variety of interface modes (e.g., synchronous, asynchronous, etc.), and may have other features that are configurable. Different end users may require different interface modes and/or different configurations of the various features. To avoid having to manufacture different memory products for every different configuration need, this configurability is frequently provided by having volatile configuration registers into which the correct configuration data may be written while the system is powered, but before the memory is to be used. Although the content of these registers may be retained as long as power is applied to the device, the configuration registers must be rewritten at each power-on or reset. Doing so may require a special boot sequence and/or special hardware support.

Non-volatile configuration data storage for a configurable memory


A tissue which has at least one fibrous ply. A hydrophobically treated foam stratum is placed on at least one of the fibrous plies in order to prevent the penetration of moisture through the tissue. A hydrophobically treated foam can also be impregnated into one or more fibrous plies in order to provide a barrier to the penetration of moisture through the tissue. The invention also comprises a process for making tissue with a foam moisture barrier.

Facial tissues, well known in the art, are widely used for blowing the nose. One of the drawbacks commonly encountered with this use concerns the problem of nasal discharge passing through the tissue and soiling the hands of the user. Accordingly, there is a need to provide a tissue with a moisture barrier so as to prevent nasal discharge and other liquids from penetrating through the tissue and soiling the user's hands. Additionally, it is desirable that the tissue be breathable, pliable and quiet.
Foam adhesives have been used to provide adhesion between plies of tissue as illustrated in British Patent Specification No. 1,599,875 issued to Sweens et al., published on Oct. 7, 1981. The drawback of this attempt is that the foam adhesive is not hydrophobic and hence would present an ineffective barrier to moisture penetration.
An attempt to prevent the penetration of moisture through tissue is illustrated in European Patent Application No. 0,144,658 published Jun. 19, 1985 in the name of Endres. Endres teaches applying a water-repellent agent to inhibit transmission of moisture through the tissue. The drawback of this teaching is that the resulting internal barrier layer is admittedly porous. Under typical use conditions, Endress fails to teach a dedicated hydrophobic stratum or layer and hence will alone be insufficient for effectively preventing the penetration of moisture through the tissue.
Other attempts in the art to prevent the penetration of moisture through tissue are illustrated in G.B. Pat. No. 2,119,709 issued to Ellam and published on Nov. 23, 1983; U.S. Pat. No. 4,489,118 issued to Endres et al. on Dec. 19, 1984 and U.S. Pat. No. 4,574,021 issued to Endres et al. on Mar. 4, 1986. In Ellam, a polyvinyl alcohol film is applied to liquid absorbent paper. In both Endres U.S. Pat. No. 4,489,118 and 4,574,021, a plastic film is applied to the inner layers of multi-layered tissue. All of these teachings suffer from the drawbacks of being non-porous, non-breathable, stiff and noisy.
Accordingly, the object of this invention is to provide tissue with an effective moisture barrier that is breathable and neither stiff nor noisy. A further objective of this invention is to incorporate a hydrophobic foam into tissue, thereby providing a tissue with an effective barrier to the penetration of moisture.

Various embodiments include apparatus and methods to measure a parameter of interest using a fiber optic cable. The parameters can be provided by a process that provides for multiplexed or distributed measurements. A multiplexed or a distributed architecture can include acoustic sensor units placed selectively along an optical fiber such that the acoustic sensor units effectively modulate the optical fiber with information regarding a parameter to provide the information to an interrogator coupled to the optical fiber that is separate from the acoustic sensor units.

In drilling wells for oil and gas exploration, understanding the structure and properties of the associated geological formation provides information to aid such exploration. It is important to monitor the physical conditions inside the borehole of an oil well, in order to ensure proper operation of the well. A borehole is a challenging environment, with temperatures that can approach 150 degrees C. (302 degrees F.), 175 degrees C. (347 degrees F.), or even 200 degrees C. (392 degrees F.), and pressures that can approach 25 kpsi (172 MPa, or about 1700 atmospheres), or even 30 kpsi (207 MPa, or about 2000 atmospheres). There is ongoing effort to develop systems and methods that can allow for more flexibility without significant loss of precision in systems and techniques to measure parameters downhole at a drilling site.

In a communication system, a call setup request is sent from a control unit to a first connection unit and a second connection unit to record the communication channel information of the opposite parties. And, the recorded communication channel information of the second connection unit is sent from the control unit to the first connection unit, and the communication channel information of the first connection unit is sent to the second connection unit. As a result, the first connection unit and the second connection unit are allowed to hold information communication by using their mutual communication channel information.

This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 11-282401, filed Oct. 4, 1999, the entire contents of which are incorporated herein by reference.
The present invention relates to a communication system and communication channel coupling method. In the communication system, more than one multimedia terminal (customer terminal) connected to a public network and having a function to send/receive audio or video or audio and video information, a multimedia terminal (operator terminal) located on a LAN (Local Area Network) and having a function to send/receive audio and video information, a public network connection unit having a function to send/receive information between a public network and a LAN, or a plurality of multimedia terminals and a plurality of public network connection units are arranged on a network. According to the present invention, the communication system is allowed to provide connection control between the multimedia terminals, between the multimedia terminal and the public network connection unit, or between the public network connection units.
Along with the evolution of Internet, increased is the number of systems wherein various desired types of information services are acquired through access to the computers of information service providers from users"" terminals. Furthermore, information services and commodity transactions are conducted with vocal answer while users dial up the computer systems of service providers from their telephones.
FIG. 13 is a diagram showing a conventional system configuration designed to interconnect operator terminals and user terminals. The information service system is provided with operator terminals 110 and 120, a server 100 which stores various types of service information and control information, and a PBX (Private Branch Exchange) 130 which performs information switching connections. The PBX 130 is connected to user terminals 150 and 160 via a public network 140, and connection between the operator terminals 110 and 120 and the user terminals 150 and 160 is performed by the PBX 130.
For example, if the user terminal 150 issues a communication request, the PBX 130 receives it and searches the server 100 to find an idle operator. Once the connection between that operator terminal (e.g., 110) and the PBX 130 is established, information communication is held between the operator terminal 110 and the user terminal 150 via the PBX 130. When the operator terminal 120 needs to generate a call, it searches the server 100 to acquire the telephone number of the user terminal. Once the connection between the operator terminal 120 and the PBX 130 is established, the PBX 130 calls the user terminal (e.g., 160) via the public network 140, and after its answer is confirmed, information communication is carried on between the operator terminal 120 and the user terminal 160.
In conventional information service systems, the PBX performs control on connections between terminals. For this reason, the conventional systems accommodate a dedicated unit to interconnect a switching unit and trunk lines for transmission and reception of audio and video information. There is no system implemented wherein audio and video information from a users"" telephone or a personal computer terminal connected to a public network is received at an operator terminal via a LAN in a computer system; or audio and video information from an operator terminal is transmitted to a users"" telephone or a personal computer terminal via a LAN in a computer system and, further, via a public network. For this reason, it is necessary to go through a dedicated PBX in order to establish information communication between a user terminal and an operator terminal, which made the system very costly.
This invention has been made in view of the situation described above, and allows to build up an information providers"" computer system with a server computer, etc. And, more than one operator terminal, more than one public network connection unit, and a control unit which controls connections (e.g., a call-generating unit, an answering unit, a connection control unit, a terminal, etc.) are connected on a LAN, so that the units interconnected on the LAN can hold high-speed communications between themselves by means of packet communication using TCP (Transmission Control Protocol), UDP (User Datagram Protocol), etc., and the public network connection unit and user terminals on the public network can perform conventional telephone line communications. Consequently, it is an object of the invention to provide a communication system and communication channel coupling method that can establish connection between user terminals (via a public network connection unit) and operator terminals, connection between operator terminals, and connection between user terminals (via two public network connection units) by simple procedures.
According to a first aspect of the present invention, there is provided a communication channel coupling method in a communication system wherein one or a plurality of multimedia terminals having a function to send/receive audio or video or audio and video, one or a plurality of public network connection units having a function to send/receive audio and video between the multimedia terminal and the public network connection unit or between a public network and a LAN, and a control unit are arranged on the LAN,
the method being arranged to provide connection between the multimedia terminals, between the multimedia terminal and the public network connection unit, or between the public network connection units, and comprising the steps of:
causing the control unit to send a call setup request to a first connection unit, and then to record audio and video communication channel information of the first connection unit which is obtained in response to the call setup request, so as to establish an audio and video communication channel;
causing the control unit to send the call setup request to a second connection unit, and then to record audio and video communication channel information of the second connection unit which is obtained in response to the call setup request, so as to establish an audio and video communication channel;

causing the control unit to send the audio and video communication information of the first connection unit to the second connection unit; and
establishing communication between the first connection unit and the second connection unit.
According to the first aspect, it is readily possible to implement communication coupling by sending a call setup request from a control unit (e.g., an automatic call-generating unit, an automatic answering unit, a connection control unit, a terminal, or a unit comprising a combination thereof) to the first and second connection units desired to interconnect, and mutually indicating the communication channel information contained in their answer signals.
According to a second aspect of the present invention, there is provided a communication channel coupling method in a communication system wherein one or a plurality of multimedia terminals having a function to send/receive audio or video or audio and video, one or a plurality of public network connection units having a function to send/receive audio and video between the multimedia terminal and the public network connection unit or between a public network and a LAN, and a control unit are arranged on the LAN,
the method being arranged to provide connection between the multimedia terminals, between the multimedia terminal and the public network connection unit, or between the public network connection units, and comprising the steps of:
causing the control unit to send a first call setup request to a first connection unit, and to mutually send/receive communication channel information therebetween;
causing the control unit to send the first call setup request to a second connection unit, and to mutually send/receive communication channel information therebetween;
causing the control unit to send a transfer request to the first connection unit, after communication between the control unit and the first and second connection units is established;
causing the first connection unit, which has received the transfer request, to send a second setup request to second connection unit, so as to cause the first and second connection units in response thereto to mutually send/receive communication channel information therebetween through the control unit;
causing the first and second connection units to disconnect communication with the control unit, after the first and second connection units mutually receive the communication channel information therebetween; and
establishing communication between the first connection unit and the second connection unit.
According to the second aspect, it is readily possible to implement communication coupling by sending a call setup request from the control unit to the first and second connection units desired to be interconnected, by receiving the communication channel information contained in their answer signals, and thereafter, by indicating the mutual communication channel information between the first connection unit and the second connection unit, pursuant to a communication channel transfer request, while disconnecting all the communication channels between the control unit and the first connection unit and between the control unit and the second connection unit.
According to a third aspect of the present invention, there is provided a communication channel coupling method in a communication system wherein one or a plurality of multimedia terminals having a function to send/receive audio or video or audio and video, one or a plurality of public network connection units having a function to send/receive audio and video between the multimedia terminal and the public network connection unit or between a public network and a LAN, and a control unit are arranged on the LAN,
the method being arranged to provide connection between the multimedia terminals, between the multimedia terminal and the public network connection unit, or between the public network connection units, and comprising the steps of:
causing the control unit to send a call setup request to first and second connection units, and to mutually send/receive communication channel information therebetween;
causing the control unit to send the communication channel information of the second connection unit and a communication channel change request to the first connection unit, and to send the communication channel information of the first connection unit and the communication channel change request to the second connection unit, after communication between the control unit and the first and second connection units is established;
causing the first and second connection units, which have received the communication channel change request, to record the communication channel information of the second and first connection units, respectively, and to terminate communication with the control unit; and
establishing information communication through a communication channel thus changed between the first connection unit and the second connection unit.
According to the third aspect, it is possible to couple a communication channel for audio and video signals between the first connection unit and the second connection unit desired to interconnect, while the control line between the control unit (e.g., a call-generating unit, an answering unit, a connection control unit, or a terminal, etc.) and the first and second connection units is held on, by sending a call setup request from the control unit to the first and second connection units, by receiving the communication channel information contained in the received answer signals and establishing the connection, and by indicating the communication channel information and communication channel transfer request of the second connection unit to the first connection unit, and indicating the communication channel information and communication channel transfer request of the first connection unit to the second connection unit.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.

Communication system and communication channel coupling method


A method for repairing a part and the resulting is disclosed. The method includes positioning a plug having an inner braze element coupled thereto into a cavity defined by an internal surface of a component. The cavity has a circular cross-section at the external surface of the component. The plug completely fills the circular cross-section and the inner braze element is within the cavity. A braze paste is positioned at least partially around the plug at the external surface. The component is positioned such that the inner braze element is above the plug. The component is subjected to a thermal cycle to melt the inner braze element around the plug, completely sealing the cavity by forming a metallurgical bond with the plug and the internal surface of the component. During the thermal cycle the braze paste is melted to form a metallurgical bond with the plug and external surface.

The disclosure relates generally to industrial machine part repair or manufacture, and more particularly, to superalloy parts having circular cross-sectional openings on an external surface.
Hard-to-weld (HTW) alloys, such as nickel-based superalloys and certain aluminum-titanium alloys, due to their gamma prime and various geometric constraints, are difficult to join when the gamma prime phase is present in volume fractions greater than about 30%, which may occur when aluminum or titanium content exceeds about 3%. As used herein, an "HTW alloy" is an alloy which exhibits liquation, hot and strain-age cracking, and which is therefore impractical to weld.
Non-weldable (NW) alloys are typically precipitation hardenable or solid-solution strengthened alloys which cannot be practically welded in an industrial setting and at an industrial scale, are only weldable under prohibitively extreme conditions, and, as such, are generally regarded as not being weldable. As used herein, an "NW alloy" refers to alloys having titanium-aluminum equivalents (or combined percentages of composition, by weight) of about 4.5 or higher. NW alloys may include nickel-based alloys in which the primary hardening mechanism is via the process of precipitation, cobalt alloys which are solid solution strengthened, and alloys which require heating immediately prior to and during welding to at least about 1,000 degrees Celsius (° C.).
These HTW and NW alloys may be incorporated into components of gas turbine engines such as airfoils, blades (buckets), nozzles (vanes), shrouds, combustion parts, transitions pieces and other hot gas path (HGP) components. Incorporation of HTW and NW alloys may be desirable due to their often superior operational properties, particularly for certain components subjected to the most extreme conditions and stresses. However, the poor weldability inherent in HTW and NW alloys complicates servicing and repairing components incorporating these alloys.
Industrial machine parts such as airfoils, blades (buckets), nozzles (vanes), shrouds, combustion parts, transitions pieces, and other hot gas path components may have hundreds or thousands of cooling holes that provide fluid flow paths. HGP components in turbomachinery such as turbine blades and nozzles, are exposed to extreme stresses and environment. Occasionally, the machine part can have too many cooling holes, or the cooling holes are in the wrong location or the cooling holes are oversized. These machine parts need to be serviced to eliminate the improperly machined holes. Advances in turbomachinery technology, however, have led to the use of more advanced materials such as superalloys like high gamma prime superalloys, which cannot be repaired using conventional techniques.
Repairs of improperly machined holes in components typically involve positioning a plug with the proper diameter to fit the hole. The process presents a number of challenges. First, the plug must match the diameter of the improperly machined hole. Thus, the plug must be machined after measurement of the diameter of the improperly machined hole to match the size of the hole. Further, there must be a gap between the component and plug to ensure proper brazing. In addition, if the plug is inserted vertically, the plug may drop out. Alternatively, if the plug is inserted horizontally, there is no gap between the plug and the component. There is no guarantee the one braze cycle can fix the improperly machined hole. The plug may move during the brazing process and rework may be required due to voids, lack of braze, over flow, etc. This situation creates an unacceptably long repair cycle.
