Abstract: The present invention provides an apparatus for supporting a steering wheel in a vehicle during normal vehicle handling and is breakable in response to an impact situation. The apparatus includes a member attachable to a vehicle and a steering column connected to the member for sliding movement. The apparatus also includes a capsule for connecting the member and the steering column to one another to prevent the sliding movement during normal vehicle handling. The capsule maintains the member and the steering column relative to one another, overcoming forces urging movement between the member and the steering column relative to one another, up to a first predetermined level of force. When the forces reach the first predetermined level, such as in an impact situation, the capsule breaks and releases the member and the steering column relative to one another.

Abstract: The present invention creates a virtual sensor plane by arraying two one-dimensional light sensors at right angles to one another wherein the shaft of a joystick extends perpendicularly through the virtual sensor plane. With this configuration, the sensor plane can detect traditional joystick rotation around a point along its axis as well as a herein-disclosed true rotation of the joystick around the joystick axis itself. Between the light sources and lenses which enable light detection and the optical, rather than mechanical or electromechanical, nature of the light sensors, wear surfaces in the joystick are minimized or eliminated everywhere except, where applicable, in the universal joint at the base of joystick configurations which include such a universal joint.

Abstract: An integrated torque and position sensor is set forth for measuring the relative rotational movement between an input and an output shaft and for measuring the final angle position of the output shaft. The integrated sensor includes a wheel that rotates with the shaft. An incremental sensing mechanism detects the incremental rotation of the shaft. In response to the shaft rotating to a predetermined angle, an actuation mechanism engages the wheel with a change gear for every new revolution in which the shaft passes. A segment sensing mechanism detects the segment in which the shaft is disposed. A method is set forth to calibrate and compensate the electrical outputs generated by the integrated torque and position sensor. The method produces common amplitudes and establishes a common angle with an expected phase angle shift for the electrical outputs.

The end cap is held in place by fasteners threadedly engaging posts extending upwardly from the flange, with one of the posts extending upwardly from a female electrical connector that extends radially between the outer casing and the inner casing for supplying electrical power to the motor.

Abstract: In a vehicle frame, a console frame structure is assembled to a chassis or main frame structure using a flap retainer. The chassis includes a bracket having a slot with a forward closed end and a rear open end. The console frame structure includes a post that is inserted into the slot for assembly. A flap retainer is attached to the bracket adjacent the slot and includes a fixed portion attached near the closed end and a free portion adjacent the open end. The flap retainer defines an opening sized and shaped for receiving the post. During assembly, the flap retainer flexes so that the free portion is spaced apart from the open end of the slot to allow the post to be inserted. The flap retainer returns to a retaining position to capture the post within the opening of the flap retainer. In the event of a vehicle impact, the flap retainer secures the post to prevent the console frame structure from becoming dislodged.

Abstract: A combined gasoline and hydrogen fueling system for a gasoline-powered internal combustion engine, including, preferably, a rapid-start catalytic reformer for producing reformate gas containing hydrogen from gasoline. The reformate from the reformer is swept by air into the intake manifold of the cold engine where it is mixed with intake air and then drawn into the cylinders and ignited conventionally to start the engine. A computer-based reformer control system optimizes the amount of reformate formed and the resulting reformate/air mixture. The reformer control system interfaces or is integral with a computer-based gasoline and air supply system for the engine, the two systems cooperating to optimize a mixture of gasoline and reformate in the intake manifold at all times during warming of the engine and its exhaust catalyst to steady-state operating temperature. Preferably, flow of reformate is terminated thereafter.
