Patent CA-2094409-A1 (CA)
Inventor: AUERBACH JOSHUA S
IPC: H04L12/18
Filed: 1993-04-20
Abstract: In a multicast network communication system, administration of the communication path making up the multicast tree itself has been separated from control and administration of the network.  Creation of a multicast distribution tree and control over the membership thereof, is separately controlled independently from the creation and use of the tree transmission path used to communicate among the members of a multicast set.  Transmission distribution trees are set up when a transmission request is received and the properties of the transmission path that is required are known.  Transmission paths are created and controlled by all nodes in the communications system, each node having necessary control code and processors for responding to requests from set members to transmit a message to groups of users by creating and activating the necessary tree communication path distribution linkages.   A distribution tree is created by the Tree Leader by generating a tree address using a random number generator.  A tree address correlator is generated utilizing network and node identifiers unique for the network, and a list of subnodes or users connected for each member of the multicast tree set is generated.  Using this information, a tree distribution path is computed to cover all of the subnodes required and a tree set up request message is sent by the Tree Leader along a computed path to each involved subnode.  Each subnode returns a message indicating whether the tree address is already in use or is available for use.  Successfully negotiated tree addresses are marked at the path link initiation and termination points at each node through the network.

Inventor: BALDWIN DWIGHT G
IPC: G06K7/10
Filed: 1991-11-12
Abstract: 2096635 9211612 PCTABS00014 A novel bae code and optical reader for scanning the same. The bar code consists of two parallel channels of marks and spaces representing bit sequences, a given bit in one sequence being associated with a bit in the other sequence, forming successive bit pairs. The data is encoded in the logical exclusive-or combination of the bit pairs. An alternating clock scheme is further used to encode the data, which limits the width of any mark or space to twice the minimum width. The optical reader includes two optical detectors connected to a microprocessor which records the time intervals between mark/space transitions in each channel. These time intervals are used to reconstruct the bit sequences in each channel; the bit sequences may then be correlated and the XOR operation performed, yielding the encoded data.

Title: Method for resealing a toner cartridge
Inventor: CHITOURAS COSTAS G
IPC: B65B7/28
Filed: 1991-12-06
Abstract: An original equipment type seal for recharger toner cartridges can be installed without splitting the cartridge itself, by screening a border of "hot-melt" type adhesive onto a strip of polyester. The softening or melting point of the adhesive is chosen to be above that of the toner powder, but below that of the cartridge. The polyester seal is inserted into the cartridge with a metallic insertion tool. Heating the tool, or inserting a hot tool, will cause the adhesive to melt and seal the cartridge. The insertion of a "pressure tool" incorporating a magnet into the fill hole in the cartridge allows one to bring about an intimate contact between the adhesive and the cartridge. The utilisation of wax-based adhesives and a cold, and then heated, insertion tool, together with a magnetic pressure tool is the preferred embodiment.

Inventor: SWAMINATHAN KUMAR
IPC: G10L25/93
Filed: 1993-05-26
Abstract: A high quality low bit rate audio codec having a reproduced voice quality that is comparable to that of a full rate codec compresses audio data sampled at8 Khz e.g., 64 Kbps PCM to 4.2 Kbps or decompresses it back to the original audio or both. The accompanying degradation in voice quality is comparable to the standard 8.0 Kbps voice codes. This is accomplished by using the same parametric model used in traditional CELP coders but determining quantizing encoding and updating these parameters differently. The low bit rate audio decoder is like most CELP decoders except that it operates in two modes depending on the received mode bit. Both pitch prefiltering and global postfiltering are employed for enhancement of the synthesized audio. In addition built-in error detection and error recovery schemes are used that help mitigate the effects of any uncorrectable transmission errors.

Abstract: AUTOMATIC BLOOD PRESSURE MONITOR EMPLOYING   ARTIFACT REJECTION METHOD AND APPARATUS                      Abstract of the Disclosure A blood pressure monitor capable of measuring blood pressure in the presence of artifact. One embodiment of the blood pressure monitor uses a detector to generate a trigger signal on the occurrence of the R-wave or other point on the ECG waveform. Oscillometric waveform samples taken at the same time after each trigger signal are then summed with each other over many heartbeats to generate an average oscillometic waveform that is used to determine blood pressure by conventional means. Another embodiment of the blood pressure monitor stores oscillometric waveform samples over many heartbeats. The monitor then assumes that the period of the heartbeat has a variety of durations, and it derives respective sets of composite samples by summing the stored samples having the same temporal relationship to the start of each assumed period. The set of composite samples corresponding the a waveform that best matches an actual oscillometric wave is then used to determine blood pressure by conventional means.

Abstract: ABSTRACT            This invention relates to a heat exchanger located  in  a  wall  (20, 21)  and  comprising  a plurality of channels A and B.  The channels A and B are formed so that rotation thereof causes air to be pumped into the channels along a first communication way defined by the channels A for relatively hotter air and along a second communication way defined by the channels B for relatively cooler air in contra flow.  Heat is transferred across channel separating walls (3).   The inertial force of rotation acts on temperature induced local density variations within the respective channels to rapidly take heated or cooled air from the boundary layer of the walls (3) resulting in bulk mixing with air in the respective channels.

Title: Digital high definition television video recorder with trick-play features
Inventor: NAIMPALLY SAIPRASAD V
IPC: H04N21/4147
Filed: 1994-02-18
Abstract: A signal processing system for a high resolution digital video tape recorder (VTR) includes circuitry which processes the high resolution video signal to produce a relatively low resolution video signal which may be recorded on the tape with the high resolution video signal. The low resolution video signal is encoded using intra-frame techniques and recorded in fixed-length segments which appear at predetermined locations in the tape tracks. Low resolution segments representing images in different frames may be recovered and combined to produce an image which is suitable for display in trick-play modes. During normal play modes, the data stream representing the high resolution image is recovered in sequence. Accordingly, this high resolution image may be encoded using predictive coding techniques as well as intra-frame techniques.

Title: Data compression for speech recognition
Inventor: HUANG XUEDONG
IPC: G10L25/03
Filed: 1994-08-16
Abstract: A data compression system greatly compresses the stored data used by a speech recognition system employing hidden Markov models (HMM). The speech recognition system vector quantizes the acoustic space spoken by humans by dividing it into a predetermined number of acoustic features that are stored as codewords in a vector quantization (output probability) table or codebook. For each spoken word, the speech recognition system calculates an output probability value for each codeword, the output probability value representing an estimated probability that the word will be spoken using the acoustic feature associated with the codeword. The probability values are stored in an output probability table indexed by each codeword and by each word in a vocabulary. The output probability table is arranged to allow compression of the probability of values associated with each codeword based on other probability values associated with the same codeword, thereby compressing the stared output probability. By compressing the probability values associated with each codeword separate from the probability values associated with other codewords, the speech recognition system can recognize spoken words without having to decompress the entire output probability table. In a preferred embodiment, additional compressian is achieved by quantizing the probability values into 16 buckets with an equal number of probability values in each bucket. By quantizing the probability values into buckets, additional redundancy is added to the output probability table, which allows the output probability table to be additionally compressed.
