Title: Electric module latch assembly
Inventor: ROBINSON RICHARD P
IPC: H01R13/639
Filed: 1990-03-13
Granted: 1993-11-16
Abstract: ELECTRIC MODULE LATCH ASSEMBLY   ABSTRACT OF THE DISCLOSURE        An electric module latch assembly (2) includes a latch handle assembly (4) mounted to the module (6) and a keeper (8) mounted to a housing (10).  The latch handle assembly includes a U-shaped handle (18) having an elongate lever (42) pivotally mounted to one leg (22) of the handle at a latch end (46) of the lever.  The latch end has a cam surface (64) which engages the keeper.   The outer,  catch end  (44)  of the lever is configured to engage a spring-loaded catch button (50) mounted to the other leg (20) of the handle.  A disenable switch pin (72)  is mounted to the handle to resiliently engage the underside (80) of the lever so that when the lever is in the latched position, the lever keeps the disenable switch pin depressed.  The pin is long enough to engage an enable switch (96)  within the housing when so depressed.   The initial movement of the lever away from  (and the  final movement towards) the handle permits the electrical connectors (12, 14) coupling the module and housing to be disconnected  (and connected) under no-load conditions.  The keeper is mounted to the housing so that it can move a short distance towards and away from the housing while being spring biased (70) towards the housing.

Title: Echo canceler-suppressor speakerphone
Inventor: FORD WILLIAM A
IPC: H04B3/20
Filed: 1990-05-30
Granted: 1994-08-02
Abstract: Abstract of the Disclosure An echo canceler-suppressor speakerphone arrangement effectively addresses the limitations of regeneration and reverberant return echo inherent in the design of speakerphones. The tendency for regeneration is eliminated by employing adaptive echo cancellation in the receive path of the speakerphone arrangement to cancel speakerphone talker echo across a hybrid and thereby reduce the local loop gain to below unity. And the generation of a reverberant return echo to the far-end party is avoided by employing adaptive echo suppression in the transmit path of the speakerphone arrangement. Near-full and full duplex operation are regularly achieved since the receive path remains open at all times and the transmit path has its gain reduced only to the level necessary to suppress excessive reverberant return echo.

Title: Method for high speed data transfer
Inventor: STERLING EDWARD W II
IPC: G06F13/00
Filed: 1990-06-15
Granted: 1996-10-29
Abstract: The  method  of  this  invention  comprises  an  efficient technique   for   transfer   of   information   over   a communication link between first and second processors, the processors employing blocks of data on a repetitive basis.  Each processor includes means for storing copies of used blocks of data.  A block of data currently used (or displayed) in the second processor is called an "old" data block and a block of data to be transmitted from the first processor to the second processor is called "new" data block.   The method includes the steps of storing identical copies of used data blocks and the old data block in the memories of the first and second processors. The  new  data  block  is  then  compared  in  the  first processor to stored data block copies to determine if the new  data  block  equals  a  pre-established  level  of similarity with any of the stored data block copies.  If a stored data block is found to equal the pre-established level of similarity with the new data block, the method contemplates  transmission  to  the  second  processor  of information regarding the differences between the new data block and the similar stored data block, as well as the  identity  of the  similar stored data  block.   The second processor then proceeds to access its copy of the identified similar stored data block and to alter that data block in accordance with the difference information transmitted from the first processor.

Title: Phase modulated fiber optic gyro accommodating angular rate reversals
Inventor: ISHIGAMI MOTOHIRO
IPC: G01C19/72
Filed: 1992-02-26
Granted: 1995-12-05
Abstract: The present invention relates to a phase modulated fiber optic gyro that accommodates angular rate reversal.  The gyro is a linear phase ramp type in which clockwise and counterclockwise light beams propagate through a looped optical transmission line.  A ramp signal is produced that provides each of the light beams with a ramp phase of a slope which cancels their phase difference corresponding to an input angular rate to the optical transmission line and a biasing signal which causes the phase difference between the both light beams emitted from the optical transmission line to alternate between +.pi./2 rad and -.pi./2 rad.  The input angular rate is obtained on the basis of the frequency of the ramp signal.
