Patent CA-2200475-A1 (CA)
Title: An ultrawide-band communications system and method
Inventor: FULLERTON LARRY W
IPC: H04B1/69
Filed: 1995-09-20
Abstract: An impulse radio communications system using one or more subcarriers to communicate information from an impulse radio transmitter (901) to an impulse radio receiver (1400). The use of subcarriers provides impulse radio transmissions added channelization, smoothing and fidelity. Subcarriers of different frequencies or waveforms can be used to add channelization of impulse radio signals. The impulse radio uses modulated subcarrier(s) for time positioning a periodic timing signal or a coded timing signal. Alternatively, the coded timing signal can be summed or mixed with the modulated subcarrier(s) and the resultant signal is used to time modulate the periodic timing signal. Direct digital modulation of data is another form of subcarrier modulation for impulse radio signals. Direct digital modulation can be used alone to time modulate the periodic timing signal or the direct digitally modulated periodic timing signal can be further modulated with one or more modulated subcarrier signals.

Title: Simultaneous processing by multiple components
Inventor: YOSHIMOTO HITOSHI
IPC: G06F13/40
Filed: 1995-10-13
Abstract: A system for simultaneous processing of multiple data streams by multiple components of a computer system. The system expedites simultaneous acquisition, processing, displaying, transferring, retrieval, and storage in an arrangement with a CPU (10), I/O devices (18, 22), loopback connections and optional multiple memory banks (26, 28, 30, 32) connected to a crossbar switch matrix (CBSM) (16). A system disk (14) is separately connected to the CPU (10) on a CPU bus (12) and is isolated physically and electrically from the other components. During transfer of data to or from any of the devices connected to the CSBM (16), the CPU (10) carries out its periodic routine system overhead operations without interrupting data flow to and from other devices because the CPU (10) has a separate CPU bus (12) providing a connection to the system disk and other system components. Thus data transfer operations are continued uninterrupted and completed expeditiously.

Patent CA-2207529-A1 (CA)
Inventor: IGLEHART DAVID
IPC: H04M9/10
Filed: 1997-06-09
Abstract: An improved speakerphone which may be viewed as a modification of a conventional half-duplex speakerphone that includes transmit and receive attenuators for alternatively isolating either a speaker ora microphone from a phone line. The attenuators are controlled by a controller that compares a signal generated by the microphone with a signal received on the phone line to determine which of the transmit or receive attenuators should be turned on. In the present invention, a first variable gainamplifier is connected so as to amplify the signal generated by the microphone prior to the signal being connected to the controller, and a second variable gain amplifier is connected so as to amplify the signal received on the phone line prior to the signal being connected to the controller. The first and second variable gain amplifiers have adjustable gain controls that are connected such that the gain of the first variable amplifier is decreased when the gain of the second variable amplifier is increased and vice versa. The adjustable gain control of one of the adjustable gain amplifiers is accessible to the user of the speakerphone and allows the user to adjust the threshold at which his voice will take over the conversation.

Title: Demineralization of milk products and derivatives
Inventor: CHAVERON MICHEL
IPC: A23C9/144
Filed: 1997-10-01
Abstract: Electrodeionization is used to demineralize milk products and derivatives with cationic ion exchange resins and weakly anionic ion exchange resins in a mixed bed, or with a strongly cationic resin alone in the dilution and concentration compartments if raw materials are treated other than more or less concentrated milk.  In the case where more or less concentrated milk is used as a raw material, the dilution compartments are filled with cationic ion exchange resins and weakly anionic exchange resins in a mixed bed.            The process enables considerable savings to be made in water and energy without using regenerating chemicals.
