Abstract: In an automatic transmission, a sensor switch is provided to monitor movement of the gearshift lever from the park position. If the gearshift lever is moved out of the park position when the ignition is off and/or the brake is not activated, the switch responds to such conditions by exciting a locking device which inhibits further movement of the gearshift lever from the park position. The locking device requires current only when the gearshift lever is being moved from the park position.

Abstract: A gearshift lever interlock is provided that allows movement of the gearshift lever of an automatic transmission from the neutral or park positions only if the brake pedal is actuated. The improved locking device locks the gearshift lever in the park position in the event of a malfunctioning electrical locking system but will not lock the gearshift lever in the neutral position. A mechanical release is provided to override the electrical gearshift lever interlock sytem.

Abstract: The invention proposes a rotor arrangement for use with an automotive Hall generator for detecting the precise position of a select or predetermined one of a plurality of pistons, or the precise rotational position of the crank shaft, of an Otto cycle engine, by providing a distinct marking on a trigger wheel preferably mounted for rotation with the drive shaft of a distributor for generating a signal in a Hall element which signal is then detected by evaluation or discriminating circuitry.

Abstract: A motor vehicle with a pneumatic leveling unit and an electrically operated compressor associated with the leveling unit which is energized only under specific pre-conditions, and with a trunk compartment with trunk lid, wherein the compressor is energized by the opening of the trunk lid, with the internal combustion engine not running, when a minimum level limit value is reached or exceeded.

Abstract: A windshield wiper is operated by a wiper motor from an electric source, with a control circuit operating the motor. This control circuit has a continuous-wipe switch which when closed operates the wiper continuously. A discontinuous-wipe switch can be closed to start an oscillator, with this oscillator connected to a backward counter which counts backwardly synchronously with the oscillator. A comparator compares the instantaneous numerical output of the counter with a fixed numerical output generated by a settable memory, and operates the wiper briefly when the two outputs agree. A set switch is connected to the memory and can reset it so that when this set switch is operated the fixed numerical output of the memory is fixed at the instantaneous numerical output of the counter, thereby setting the interval between successive wipes of the wiper.
