Patent CA-2156650-A1 (CA)
Inventor: NOMURA TOSHIYUKI
IPC: G10L19/16
Filed: 1995-08-22
Abstract: In a vector quantizer device including an input vector quantizer (11) for a current input vector of an input vector sequence to produce a first quantized vector and a predicted vector quantizer (13) responsive to the input vector sequence for quantizing into a second predicted vector a predicted vector predictive of the current input vector with quantization, a predicting unit (37) produces the predicted vector in response to a predetermined number of output vectors including such first and second quantized vectors.  Responsive to a prediction error vector between the current input and the predicted vectors, a control circuat (35) controls, at a time, input and output switches (31, 33) to supply the input vector sequence to only one selected quantizer of the input and the predicted vector quantizers and to produce as one of the output vectors one of the first and the second quantized vectors that is produced by the selected quantizer.  The first and the second quantized vectors are produced as two of the output vectors when the prediction error vector is greater and smaller than a threshold value, respectively.

Title: Ultrasonic Diagnostic Scanning for Three Dimensional Display
Inventor: SCHWARTZ GARY ALLEN
IPC: G01S7/52
Filed: 1995-08-31
Abstract: The method for producing three dimensional ultrasonic images of the interior of a body involves transmitting ultrasonic waves over a volumetric region of the interior of the body, receiving ultrasonic Doppler information signals from spatial locations within the region and processing the ultrasonic Doppler information signals to determine the Doppler power intensity received from the locations within the region. The Doppler power intensity is displayed on a spatial basis in a three dimensional presentation. The processing involves processing the ultrasonic Doppler information signals to determine the maximum Doppler power intensity received from the locations within the region. The displaying involves displaying the maximum Doppler power intensity of the locations on a spatial basis in a three dimensional presentation.

Title: System and method for awarding credits to persons who book travel-related reservations
Inventor: HEINTZEMAN SCOTT B
IPC: G06Q10/02
Filed: 1994-05-26
Abstract: A computerized system provides incentives for travel agents and similar persons to book particular travel-related reservations.  The system achieves this by awarding cumulative credits to travel agents based upon bookings of travel-related reservations.  The system receives a booking format which identifies a travel-related reservation.  The system further receives a code which identifies a travel agent or other person who entered the travel-related reservation.  Upon receiving the travel-related reservation, the system assigns cumulative credits to the travel agent identified by the code based upon the travel-related reservation.  Travel agents can thus build up credits over time based upon their bookings of travel-related reservations and use those credits to receive a particular award or prize.

Patent CA-2198622-A1 (CA)
Title: Suspension plasma spray deposition
Inventor: GITZHOFER FRANCOIS
IPC: C23C4/12
Filed: 1995-08-28
Abstract: The plasma spray method produces a material deposit on a substrate to form either a protective coating or a near net shape body, or produces a powder of a given material. The material is supplied to a plasma discharge in the form of a suspension comprising small solid particles of that material dispersed into a liquid or semi-liquid carrier substance. The suspension is brought into the plasma discharge by an atomizing probe using a pressurized gas to shear the suspension and thus atomize it into a stream of fine droplets. The plasma discharge vaporizes the carrier substance and agglomerate the small solid particles into partially or totally melted drops which are accelerated to hit the substrate and form thereon the coating or near net shape body. Alternatively, the molten drops can be solidified in-flight and collected into a vessel to produce a powder of that material.

Title: Phase detector for high speed clock recovery from random binary signals
Inventor: GUPTA ATUL
IPC: H03L7/085
Filed: 1997-04-03
Abstract: An improved phase detector for use in a phase-locked loop. In one embodiment, the input data is first frequency divided into two signals.      Two sets of three series connected latches each have the first latch receiving one of these divided data signals and each subsequent latch receiving the data output of the previous latch. The latches are enabled by alternate phases of the clock signal, where each consecutive latch has the opposite clock phase and corresponding latches from either set of three latches have identical clock phases. The clock phase of the seventh latch is opposite to that of either third latch. The data outputs of the second latches are inputs to a first XOR gate. The output of the first XOR gate is the input to a seventh latch whose output is the input to an eighth latch. The clock phase of the seventh latch is opposite to that of each third latch. The clock phase of the eighth latch is opposite to that of the seventh latch. A second XOR gate receives the data output of one third latch and the data input of its corresponding first latch. A third XOR gate receives the data output of the other third latch and the data input of its corresponding first latch. A fourth XOR gate receives the outputs of the first XOR gate and the data output of the seventh latch. A fifth XOR gate receives the output of the data output of the seventh latch and the data output of the eighth latch.      The outputs of the second, third, fourth and fifth XOR gates control current sources, which when appropriately summed and integrated, provide a phase error signal. Delay means are also added to the circuit to compensate for the latch gate delays.

Title: Method and apparatus providing personalized mailbox filters
Inventor: ROCHKIND MARK M
IPC: H04M3/42
Filed: 1997-06-25
Abstract: An  electronic  mailbox  filters  or  sorts  messages according to personalized or customized rules set by the owner  of  the  mailbox  through  the  use  of  address extensions.     The  addressee  will  assign  an  address extension to a prospective sender before the sender sends a message.   The sender may use this address extension when addressing and sending a message to the addressee. The addressee can also provide a specific sender with multiple address extensions so that the sender could send messages relating to particular topics or projects.   The addressee will maintain a look-up table of valid address extensions.     This  look-up  table  correlates  address extensions  with  particular  levels  of  priority.    The addressee  can  change  the  priority  associated  with particular   messages   by   reassigning   the   priority associated  the  corresponding  address  extension  in  the look-up table.  Thus, even if a sender continues to use a particular address extension in the sending address, the mailbox  may  no  longer  treat  such  messages  with  the priority level expected by the sender.
