Patent CA-2113172-A1 (CA)
Inventor: DEAM DAVID
IPC: H02M7/00
Filed: 1992-07-09
Abstract: 2113172 9301648 PCTABS00019 A low impedance, high power bus can be applied as a high power supply bus between a constant voltage source (50) and a plurality of switching cells (64, 66) positioned at varying locations along the bus, and as branch bus for the switching cells. The high power bus includes two conductive bars (58, 60) positioned so that the current flow therethrough is balanced (equal and opposing), and the magnetic field is substantially confined between the bars.  The bus includes a dielectric positioned between the conductive bars (74, 76, 78) that extend along the power supply bus, so that a main bus is created by the combination of the AC extension bars and the DC power supply bus, and the sum of the currents in the bars is approximately zero at all locations in the bus. The power bus lessens or even obviates the need for the snubber networks commonly used to reduce transients, and reduces the strength of magnetic fields and electric fields that could otherwise interfere with neighboring electrical components.

Filed: 1994-01-13
Abstract: ABSTRACT           A novel hybrid air bag inflator system includes a differential pressure monitoring switch which comprises a sealed module containing a gas under a threshold pressure mounted in a gas-bag filler tank.  The capsule comprises a movable diaphragm connected to a fixed top plate and the diaphragm is supported on a shaped mandrel mounted on a switch body. The switch body and the mandrel are provided with a central aperture through which moves a movable piston and the movable piston forms a support for switch contacts which are normally open until the pressure in the hybrid air bag gas filler tank falls below a predetermined operable reference pressure at which time the switch contacts reach a closed position indicative of a failed or inoperative hybrid system.

Abstract: ABSTRACT      CATALYST MONITORING USING EGO SENSORS          A method of monitoring, while on board an automotive vehicle, one or more of catalyst performance, engine misfire, and combustion quality, the vehicle having an internal combustion engine (13) equipped with a catalyst (21) for converting noxious emissions of the engine, comprising: (i) exposing at least one pair of EGO sensors to (55,56,59,60) substantially the same emissions either exiting from the engine or from the catalyst, one (55) of the EGO sensors having its electrode highly catalytic, and the other sensor (56) having its electrode low-to-noncatalytic; (ii) comparing the outputs of the sensor electrodes (amplitude, frequency, or phase shift) to determine if there is a sufficient differential to indicate a misfire or poor combustion in the case of the sensors being located downstream of the engine exhaust but upstream of the catalyst, or indicating poor catalyst efficiency in the case of the sensors being placed substantially immediately downstream of the catalyst.  Two pairs of sensors (55,56,59,60) may be used, a first pair being placed substantially immediately upstream of the catalyst (21) and the second pair being placed substantially immediately downstream of the catalyst, the pairs of EGO sensors being incorporated into a closed-loop feedback control of the engine fuel control system.

Title: Sun visor extension
Inventor: BOUDREAU NORMAND
IPC: B60J3/00
Filed: 1994-06-10
Abstract: Abstract of the disclosure: A sun visor extension adapted to be slidably mounted over a standard visor of a motor vehicle for increasing the coverage area and minimizing glare across the windshield of the motor vehicle. The sun visor extension has a substantially parallepiped shaped hollow sleeve made up of a front panel and a rear panel, both panels being linked by longitudinal side panels.  A biasing block is fixed to the inner surface of one of the side panels.  The biasing block is compressible between an uncompressed configuration and a compressed configuration.  In the uncompressed configuration, the block functionnally prevents relative displacement between the sleeve and the standard sun visor, while with compressed configuration the block allows such displacement.  A biasing element biases the block towards its uncompressed configuration.

Title: Device for moving a mobile robot
Inventor: ECHIGO TOMIO
IPC: H04N13/239
Filed: 1994-09-19
Abstract: DEVICE FOR MOVING A MOBILE ROBOT            Abstract To run and move a mobile robot safely and effectively in an environment obtained from a plurality of different sensors. Sonar data given as distance information for an object is used to interpret the surface configuration of an object at a sonar interpretation section. Three-dimensional information about stereo data based on image signals from stereo cameras is used to interpret the surface configuration of an object at a stereo interpretation section.   At a hypothesis generation section,  a geometrically consistent interpretation is used taken  from interpretations  obtained  from  each  sensor  to generate a hypothesis giving the configuration of an object. A table is used to determine which data is assigned priority, sonar or stereo, to check sensor data corresponding to the surface configuration of the hypothesis against actual sensor data with the passage of time to verify the hypothesis. The mobile robot moves to avoid an obstacle, or its movement is directed, in accordance with the hypothesis with respect to the current environment by referencing the run route.

A control unit supplies resistance signals to the power source to determine the amount of resistance  to  be  applied  to  movement  of  the  foot stirrups.    The  amount  of  resistance  is  geared  to simulate  the  steepness  of  terrain  over  which  the operator  is  moving,  with  greater  resistance  being applied when the terrain is uphill and less resistance being applied when the terrain is level or downhill, for example.
