Patent CA-2299719-A1 (CA)
Title: Cigarette lighter receptacle
Inventor: DEVENS C SCOTT
IPC: B65D85/10
Filed: 1998-08-03
Abstract: A package (5) for retail distribution of cigarettes forms a container to receive and dispense cigarettes. The container includes a cigarette lighter receptacle (15) disposed on an outer surface of a wall of the container (10).  The cigarette lighter receptacle includes at least an outer wall (45) that is connected to the container by a pair of spaced side walls (50). These side walls are inwardly foldable so as to position the outer wall substantially flush with the container wall (35), when the receptacle is not being used, and outwardly deployable so as to form the cigarette lighter receptacle (15). Reverse foldable portions are separated from the remainder of the receptacle (15) by a slit to define a bottom stop (60) for the lighter (17).  The receptacle is preferably supplied with the cigarette package, but also can be a separate item attachable to any convenient surface.

Title: A method of and a device for coupling optical fibres and opto-electronic components
Inventor: PESANDO LUCA
IPC: G02B6/42
Filed: 2000-03-02
Abstract: A method and device for coupling optical fibres and opto-electronic components. In the fibre, a reflecting surface is created that is generically tilted with respect to the main propagation path of the optical radiation in the fibre, so as to originate by reflection an additional propagation path that is generically deflected with respect to the main propagation path. In a mounting support common to the fibre and the related opto-electronic component, a groove is made along an external face so as to accommodate the optical fibre in a tight condition. The groove is then covered through a laminar cover, that is transparent to the radiation and has a flat surface. The fibre is inserted into the groove in order that the deflected propagation path passes through the cover of material transparent to the radiation, and the opto-electronic component is mounted on the cover in alignment with the deflected propagation path.

Title: Low power current-to-frequency converter circuit for use in implantable sensors
Inventor: GORD JOHN C
IPC: G01R19/252
Filed: 1998-09-11
Abstract: A low power current-to-frequency converter circuit provides an output frequency signal F OUT having a frequency that varies as a function of a low level analog input current signal. The analog input current signal is typically generated by an implantable sensor element, designed to sense a particular substance or parameter within body tissue or fluids to which the sensor is exposed, with the magnitude of the analog signal providing a measure of the sensed substance or parameter.  Conversion of the low level analog current to the output frequency signal facilitates transmission of the data signal over a shared data bus and other digital processing of the data signal. The current-to-frequency converter circuit is fabricated from low power FET-based integrated circuits, and includes an operational amplifier having its positive input terminal connected to a storage capacitor that is charged by the analog input current signal, a voltage-controlled oscillator driven by the charge (voltage) on the storage capacitor that produces the output frequency signal, and a charge pump circuit that pumps a discrete amount of charge off of the storage capacitor during each cycle of the output frequency signal.

IPC: H05K3/30
Filed: 2000-05-09
Abstract: A novel electrical connection device for surface-mounting on a circuit board. The electrical connection device includes at least two terminal members. Each terminal member includes a retaining surface serving as a point of electrical contact between the terminal member and the circuit board and as a point of solder-anchoring for securely mounting the electrical connection device to the PCB. Further, each terminal member includes a contact portion providing for the mounting of an electrical component onto the circuit board, as well as serving as a point of electrical contact between the circuit board and the electrical component. The terminal members are mounted on a strip of insulating material that holds them in the proper spacial relationship until they have been secured to the circuit board. The strip reduces pin-misalignment that can cause difficulties in engaging a mating electrical component on the electrical connection device. Optionally, the strip can be removed from the pins once the pins are fixed on the circuit board.

Filed: 1999-03-17
Abstract: There is described a BiCMOS switch circuit which allows a low voltage CMOS  signal to control a bipolar current source or sink circuit. The circuit includes a current mirror circuit, drawing a constant current through a first bipolar transistor. The collector of that transistor is connected firstly through a second bipolar transistor to a circuit output, and secondly through a CMOS transistor to a positive voltage supply. Depending on an input control signal supplied to the gate of the CMOS transistor, that device can be switched on or off. When the CMOS transistor is switched off, the constant current through the first bipolar transistor is drawn through the circuit output. When the CMOS transistor is switched on, the constant current through the first bipolar transistor is drawn through the CMOS transistor, and the output current is zero.

Title: Wheelchair seating system including trapezoidally sectioned fluid bag
Inventor: NACHOD JULIUS E
IPC: A61G5/10
Filed: 1999-04-05
Abstract: The present invention relates to a seat cushion assembly for use, in particular, in a wheelchair. The assembly includes a sculpted or molded foam base having exterior sidewalls profiled to accommodate a wheelchair frame, and a seating surface to provide some positioning support to the occupant.  Further, the base includes a well area to be positioned under the ischial tuberosities of the occupant and including means for the removable attachment of a flexible envelope containing a fluid filling material. The envelope is comprised of upper and lower elastomeric sheet materials sealed about the perimeter. It is divided by internal seal sections so as to inhibit fluid migration within the envelope. These internal seals define a tapering flow orifice which provide for gradual restriction of a flow channel to permit flow so as to avoid failure inhibiting fluid migration. The envelope has a surface area which exceeds the surface area of the well and includes attachment means on the bottom side to encourage a gathering of the envelope into the well for proper cushioning effect. In addition, the assembly can include a rigidizer to enable the cushion to be used in a sling-type wheelchair seat.
