Title: Packet data flow control for an isdn d-channel
Inventor: LY CHI-VIEN
IPC: H04L12/56
Filed: 1991-11-26
Granted: 1998-02-17
Abstract: A plurality of terminals, each responsive to RR (receive ready) and RNR (receivenot ready) messages for respectively enabling and inhibiting the transmission of data packets by the terminal, are coupled to a packet handler via a multiplexed path. In order to limit each terminal to an allocated bandwidth, for each terminal a number is stored representing a number of data bytes which the respective terminal is permitted to transmit within a timed period at its allocated bandwidth, and in each timed period a counter counts down from this number in accordance with the number of data bytes transmitted by the terminal. An RNR message is transmitted to the terminal if and when a zero count is reached, and following such an RNR message an RR message is transmitted to the terminal to enable it for the next time period. The arrangement provides a relatively instantaneous limiting of the bandwidth of each terminal to its allocated bandwidth, and can be applied independently for each direction of transmission.

Title: Motion compensated predicting apparatus
Inventor: TANAKA KOUICHI
IPC: H03M7/30
Filed: 1992-06-09
Granted: 1998-05-26
Abstract: An MC predicting apparatus which ensures a high prediction accuracy against input image signal stream and avoids arithmetic operation of an evaluation function from becoming an overhead for an image encoding process is provided.  Sequence numbers given to respective frames are discriminated, and a degree of interframe correlation is decided from a difference in sequence number of the preceding and current frames.  A reference block generator adaptively controls, depending on the degree of interframe correlation, the reference range of MC prediction of the preceding frame stored in a frame memory.  As a result, the number of times of arithmetic operation of an evaluation function for MC prediction can be reduced and a prediction accuracy can be improved.

Title: Apparatus for removing filtrate from filter media
Inventor: SNELL DARRELL E
IPC: B01D35/16
Filed: 1993-01-27
Granted: 1998-06-23
Abstract: An apparatus for separating filter cake from an endless filter web, and method for using the same, for use in conjunction with a stacked plate filter system and filter web extractor.  The filter cake and filter web separator apparatus includes a downwardly sloping support tray and a wedge-shaped plow blade having a resilient scrapper and suspended above, and generally parallel with, the support tray.  As contaminated filter web exits a plate filter and is pulled through the separator apparatus by the filter web extractor, the resilient scrapper dislodges the filter cake from the filter web as the contaminated portion of filter web passes between the plow blade and the support plate and displaces the cake off the filter web where it falls into a suitable collection container. The filter web exits the apparatus from between the plow blade and support tray having substantially all of the filter cake removed from the filter web.  In one embodiment of the invention, a suitable vacuum inlet can be disposed downstream of the plow blade to remove any residual moisture or particulate matter disposed on the filter web.  Adjustment means are provided to allow height and inclination adjustment of the plow blade relative to the support tray and separation of the two components to facilitate threading of a filter web through the apparatus.

Title: Telecommunication system with detection and control of packet collisions
Inventor: PUNJ VIKRAM
IPC: H04L12/56
Filed: 1995-10-25
Granted: 2000-04-04
Abstract: Line cards provide an input/output interface between synchronous communication channels and an asynchronous network.  The input line card translates information received from the synchronous communication channels into packets for transmission to the asynchronous network.  Each line card generates and stores packets corresponding to a time frame associated with the synchronous communication channels, A sequence is selected for the sequential transmission of packets by each input line card to the asynchronous network.  The cumulative number of packet collisions that would occur at each output line card during the predetermined time frame is determined.  If the cumulative number of collisions exceeds a predetermined delay threshold, the number of packets actually transmitted to the system is reduced preferably by denying service to new call origination requests.  This technique keeps the maximum cumulative collisions for each output line card within the predetermined delay threshold.
