Title: Zero separation force connector
Inventor: WALKUP WILLIAM B
IPC: H01R12/71
Filed: 1990-06-26
Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE   A zero separation force electrical connector which utilizes resilient energy developed and stored during mating to demate the mated contacts and separate the connector with zero separation force.   In  one  embodiment,  the  contacts  of first  and  second housing members are mated in combination to provide the stored resilient energy for subsequent demating of the contacts and the respective housing members with zero separation force.  The first housing member includes male contacts with tapered ends and the second  housing  member  includes  female  contacts  with  spring fingers.  A securing mechanism is utilized to mate the first and second housing members in combination.  During mating the tapered ends of the male contacts coact with corresponding spring fingers of the female contacts, biasing the fingers outwardly,  to store resilient  energy  therein.   Releasing  the  securing  mechanism causes the resilient energy in the spring fingers to be exerted against  the  tapered  ends  of  the male  contacts  to  demate  the contacts and separate the first and second housing members with zero  separation  force.   In  another  embodiment,  the  electrical connector consists of a single housing member containing female contacts with spring fingers and a securing mechanism which is mated  in  combination  with  the  male  pin  grid  array  of  an electronic device such as a printed circuit board.

Title: Arrangement for translating logical page addresses to corresponding real ones in data processing system
Inventor: SUZUKI KATSUYUKI
IPC: G06F12/10
Filed: 1990-12-19
Granted: 1996-03-12
Abstract: A predetermined number of logical page addresses are effectively translated into corresponding real ones. The number of the logical page addresses is determined by (M+N) bits and, each of the logical page addresses includes upper M-bit and lower N-bit.  Logical page address registers, whose number is equal to 2N, are provided to respectively store the predetermined number of logical page addresses applied.  Address translation buffers (whose number is also equal to 2N) each stores 2M real page addresses which are grouped according to each of the lower N bits.  The address translation buffers receive the upper M-bit of one of the logical page addresses, and output real addresses.   An address translation controller receives the outputs of the address translation buffers and also receives the lower N-bit, and selects the real page addresses using the lower N-bit.  The selected real page addresses are applied to a plurality of real address registers.  A page number comparator determines whether or not the upper M-bit of one of the logical page address coincides with the upper M-bit of each of the remaining logical page addresses.  The page number comparator outputs the comparison results which allow the real address(es) stored in the real address registers to be applied to a main memory.

Granted: 1994-11-15
Abstract: In a cellular mobile telephone system serving a plurality of cells, each of the cells being assigned a unique standby channel, the mobile station is assigned several standby channels and a system identifier identifying the system. The standby channels are scanned and one of the scanned channels having a highest signal level is selected. If there is a match between the system identifier of the selected standby channel and the system identifier of the mobile station, the mobile station is ready to originate or receive a call. If there is no originating or incoming terminating call, the identifier of a call setup channel specified by the standby channel is stored into a different location of a memory. Otherwise, the identifiers stored in the memory are scanned, and one of the scanned call setup channels is selected.

Title: Remotely accessible security controlled audio link
Inventor: BRIAULT NIGEL C
IPC: H04M11/04
Filed: 1992-03-10
Granted: 1996-04-23
Abstract: The security for a person in a domicile, premise, or dwelling, is increased in the effectiveness thereof, by utilizing a remotely accessible security controlled audio link, which provides a hands free telephone answering system, that operates without the utilization of any conventional telephone located in the domicile.  In a normal mode of this audio link, the telephone of a domicile is used in a conventional manner.  However, when a telephone in the domicile is not answered within a time period of a designated number of rings, then the remotely accessible security controlled audio link operates to answer the incoming call by, in effect, functioning in an equivalent way, to lift up a conventional receiver, without the conventional receiver ever being raised.  Thereafter, if a correct pulse tone entry code is entered by a person at a remote location, within a limited time period, telephone voice communications can begin and will continue between a person in or near the domicile and a person at a remote telephone location, thereby expanding the security available for a person in and around a domicile.  Also if an alarm signal is initiated by a person in and around a domicile, then an alarm mode is established.  Thereafter the remotely accessible security controlled audio link operates to bypass the privacy security features thereof, by eliminating the functions of both the ring counting delays and correct pulse tone entry codes, and instead functions to quickly establish telephone communications, while in this alarm mode of operations.

Title: Method and apparatus for sharing a telecommunications channel among multiple users
Inventor: SNYDER RAMON E
IPC: H04L29/10
Filed: 1993-04-06
Granted: 1998-04-28
Abstract: A method and an apparatus allows multiple users to share one or more data communication lines without requiring the users to actively participate in the arbitration.  The preferred embodiment comprises an ISDN Port Connection Manager (PCM) for managing the use of each of the individual channels of one or more line ports having ISDN service thereon.  The ISDN PCM manages the use of the channels between applications using such distinct access methods as the IBM Virtual Telecommunications Access Method (VTAM), TCP/IP, and Open Systems Interconnect (OSI) access methods. The ISDN PCM determines that an application needs access to an ISDN channel, determines the availability of the ISDN network and sets up the communication between the application and the network if the channel is available. If no channel is available at that time, the ISDN PCM indicates to the application when the channel becomes available so that the application may determine whether it still needs access.

Abstract: In order to produce multilayer structures made of composite materials, by draping pre-cut elementary layers over a forming die (12), an installation is proposed comprising, in addition to the forming die (12), a gripping tool (16) capable of being mounted, for example, on the articulated arm of a robot. The forming die (12) comprises a flexible membrane (28), equipped with suction suckers (58) which grip the pre-cut elementary layers. A vacuum circuit (48) enables the membrane (28) to be pressed up against a counter-shape (26) placed behind the latter, in order to shape the elementary layer picked up. When the tool (16) is brought onto the die (12), a pressure source (52) acts on the membrane (28) in order to compact the elementary layer on the die. A suction system (76, 82) keeps this layer on the die, after releasing the suction via the suckers (58). <IMAGE>

Abstract: This invention provides a method for performing three dimensional seismic surveys. In one configuration, receiver lines containing equally spaced receiver stations run in one direction while the source station lines run diagonal to the receiver station lines. The receiver stations and/or the source stations are offset to obtain a desired spatial sampling (number of bins) or multiplicity of the common mid points. In an alternate configuration, the receiver line spacing is offset by a fraction of the source station spacing and/or the source line spacing is offset by a fraction of the receiver station spacing to obtain the desired spatial sampling. These configurations provide higher spatial sampling (smaller bins) compared to the conventional geometries. The smaller bins may be combined to obtain folds (multiplicity) which is sufficient to provide desired seismic imaging while preserving the benefits provided by the higher spatial sampling by the method of the present invention.
