Patent CA-2179835-A1 (CA)
Inventor: BERTOCCI GUIDO
IPC: H04M1/72505
Filed: 1996-06-25
Abstract: A cordless telephone provides for increased features available at a portable unit that have heretofore been available only at a base unit which combines a cordless telephone fixed station and telephone answering device. The cordless telephone includes a call screening feature which allows a user at the portable unit to monitor incoming messages received over telephone lines as they are being recorded at the telephone answering device without the user having to configure the portable unit in any way during actual receipt of the message. A built-in loudspeaker is incorporated into the portable unit so that the user may easily listen to the incoming messages. Once receipt of the incoming message is completed, amplifier circuitrydriving the loudspeaker is turned off. The cordless telephone also includes a caller-ID feature which informs the user at the portable unit of the identity of a preidentified calling party before the call is answered. This operation is achieved by the user entering into a memory table in the telephone each one of a plurality of desired telephone numbers for subsequent access and comparison when a caller-ID number is received from a calling party. The user also associates with each telephone number a voice message which is subsequently generated in the loudspeaker in the portable unit in response to a favorable comparison between said caller-ID signal and said stored telephone number.

Title: Automatic steering wheel anti-theft device
Inventor: WYMAN VICTOR K
IPC: B60R25/02
Filed: 1996-09-11
Abstract: A steering wheel anti-theft system for an automobile having an ignition key switch assembly and a steering wheel wherein a pair of extendable rods are built into the transverse body of the steering wheel for radial extension and retraction in between an extended position wherein they are visible and interfere with the driving of the automobile and a storage position wherein they are retracted in the steering wheel and do not so interfere. The steering column ignition key assembly includes an electric switch which is opened and closed by turning of a key for connection or not connecting a source of electrical power to an electronically operated latches for securing said rods in extended positions and when said switch is opened or allow it to be retracted only when said switch is closed.          The disclosed latches are solenoids in the steering wheel that retract a spring loaded pin when electrically energized but when unenergizied allow the pin to be driven into a hole in the extended rod to latch it in that position. Only by operating the ignition key switch can the rods be unlatched and manually retracted and only that one key switch need be operated to unlatch the anti-theft system and start and run the automobile.

Patent CA-2188248-A1 (CA)
Inventor: WONG ANDREW K C
IPC: G06N20/00
Filed: 1996-10-18
Abstract: Automatic discovery of qualitative and quantitative patterns inherent in data sets is accomplished by use of a muffed framework which employs adjusted residual analysis in statistics to test the significance of the pattern candidates generated from data sets. This framework consists of a search engine for different order patterns, a mechanism to avoid exhaustive search by eliminating impossible pattern candidates, an attributed hypergraph (AHG) based knowledge representation language and an inference engine which measures the weight of evidence of each pattern for classification and prediction. If a pattern candi- date passes the statistical significance test of adjusted residual, it is regarded as a pattern and represented by an attributed hyper edge in AHG. In the task of classification and/or prediction, the weights of evidence are calculated and compared to draw the conclusion.

Title: Ink jet cartridge with membrane valve
Inventor: BETSCHON LUZIUS
IPC: B41J2/175
Filed: 1996-11-28
Abstract: An ink cartridge for an ink jet printer has a housing containing a,n ink storage space. An upper portion of the ink storage space is closed off by a cup-shaped membrane. A pressure reduction valve is built into a housing bottom. The storage space communicates via the pressure reduction valve with a chamber which has an opening sealed by a rubber plug. During installation of the cartridge in the print head, the rubber plug is pierced by a hollow needle so that ink may pass from the chamber to the print head. The reduction valve ensures a predetermined underpressure in chamber. This facilitates reliable operation of the print head, even with fluctuating ambient temperature, and provides efficient space utilization within the housing.

Title: Control apparatus for electrosurgical generator power output
Inventor: PATERSON WILLIAM G
IPC: A61B18/12
Filed: 1996-06-03
Abstract: A power control apparatus for an electrosurgical generator (10) is used for controlling output power from the generator (10) to the tissue or bodily fluids of a patient (11). The control apparatus rapidly determines the range of impedance of the load on the electrosurgical generator (10) and adjusts the output power accordingly. Output current and output voltage from the electrosurgical generator (10) are monitored and sent to a microprocessor (18). The microprocessor (18) runs an algorithm that rapidly determines the impedance range of the load on the generator (10). The algorithm uses computational techniques, such as comparisons and bit shifting, that avoid long division and other time-consuming operations. The microprocessor (18) can then adjust a high voltage power supply (15) that effects the radio frequency amplifier stage. A method for controlling the power of the electrosurgical generator (10), including steps in the algorithm, is also disclosed.

Title: Separator systems for well production fluids
Inventor: KOLPAK MIROSLAV MICHAL
IPC: E21B43/34
Filed: 1996-05-17
Abstract: Hydrocarbon fluid production wells and similar process flowstreams have a spiral baffle-type separator interposed in a surface flowline for separating fluids of different densities, such as gas from oil or gas from oil and from water, for example. Particulate solids may also be separated from the fluid flowstream. The separator (16) includes a spiral baffle (58) of single or multiple diameters interposed in an elongated cylindrical casing (72) connected at its opposite ends to suitable fittings whereby the separator may be connected to conventional fluid flowlines on the surface just downstream of a wellhead or otherwise in a process flowstream. Multiple spiral baffle separators may be connected in series to provide multiple stages for separation of fluids of different densities. The separator is particularly compact, mechanically uncomplicated and may be easily adapted to be interposed in well production fluid flowlines or conduits for process flowstreams.
