Title: A distributed buffering system for atm switches
Inventor: WILLS JEFFREY MERLIN
IPC: H04L12/56
Filed: 1997-12-11
Abstract: The present invention provides for an ATM switch for transferring ATM cells from input channels to output channels.  The switch has a plurality of input and output ports, each connected to input and output channels respectively. The ATM switch also has a switch block connected between each one of the input ports and each one of the output ports to convey the cells from the input ports to the output ports, and a backpressure signal circuit.  Each input port has an input buffer which holds cells which arrive faster from an input channel than the input port can transmit to the switch block, and each output port has an output buffer holding cells when the cells arrive faster from the switch block than the output port can transmit.  The backpressure signal circuit sends a signal from a congested output buffer to those input port buffers which have transmitted a cell to the output buffer (during congestion) so that the input port buffers cease transmission.  The cells destined for the output buffer are then stored in the input port buffers.

Title: Call forwarding in a mobile communication system
Inventor: LANTTO JOERGEN
IPC: H04B7/26
Filed: 1996-07-03
Abstract: A digital cellular communication system supports call forwarding with better speech quality by avoiding unnecessary speech decoding when a call is forwarded from one network or exchange to another. A new information element that contains the network code of an originating mobile services switching center (MSC) is added in an initial address message, so that the address of the originating MSC can be properly determined by a terminating MSC or, if call forwarding has been initiated, by a forwarded-to MSC. A structured dialog is used for sending a speech coding request to the originating MSC in which a return result signal acknowledging the request is sent to the correct receiver in the terminating MSC or, if call forwarding has been initiated, in the forwarded-to MSC.

Title: Method for randomly accessing stored imagery and a field inspection system employing the same
Inventor: VAN DEN BOSCH JEFFREY A
IPC: G06T1/00
Filed: 1996-08-28
Abstract: The present invention relates to a field inspec-tion system (100) for compressing video signals received from a field inspection video camera (14) into com-pressed video data and for burning the compressed video data on a compact disc (118) along with an electronic logsheet. The electronic logsheet includes a listing of suspected defects or anomalies and associated pointers to reference frames in the compressed video data. The electronic logsheet may be displayed and an operator may access a portion of the field inspection video show-ing a listed defect by clicking a mouse button (116) when a pointer icon is positioned on the listed defect. To per-form this task, the present invention utilizes a technique for randomly accessing the compressed video data in which reference frames included therein are used as ac-cess points to the video footage.
Patent CA-2236954-A1 (CA)
Title: Data detector and method using the same
Inventor: JEON JIN-KYU
IPC: H03M13/41
Filed: 1998-05-06
Abstract: A data detector and a data detection method. The data detector includes: a converter for converting a received signal into digital data according to a sampling clock signal; a maximum likelihood decoder for performing maximum likelihood decoding of the digital data; and a generator for measuring a phase difference between sampling points of the digital data and optimal detection points of the received signal, and for generating a control signal for changing the phase of the sampling clock signal according to the measured phase difference. The phase of the sampling points as the data detection points matches that of the optimal detection points, so that error caused by difference in phase is minimized, thereby enhancing the performance of the maximum likelihood decoder, and the overall performance in detection of reproduced data.

Patent CA-2242731-A1 (CA)
Inventor: MARCHAND PHILIPPE
IPC: H04B1/707
Filed: 1998-07-30
Abstract: The invention concerns radio systems implementing spectrum spreading by frequency-coded transposition multiplexing and continuous phase modulation. The invention consists in the fact that the fixed-frequency oscillator that is normally used in the receiver to provide the reference signal to a mixer (26) is replaced with a bypass circuit (40) which samples part of the spectrum-spread signals transmitted, according to binary sequences of a first type. Signals received from a remote transmitter transmitting signals that are spectrum-spread according to binary sequences of a second type are, after frequency changing (26), amplification (28) and frequency demodulation (32), unspread in a circuit (32) using binary sequences of the second type, making it possible to distinguish the useful binary signals from the remote transmitter using a digital demodulator (42). The invention is applicable to transmitters/receivers for radio-relay systems.
