Abstract: In electronic systems for power adjustment in motor vehicles, conventional mechanical linkages or Bowden cables are replaced or supplemented by the transmission of electric signals. Such an electronic power adjustment device contains a control unit (6) which acts on the power adjustor (9) via an electric actuator (8). In order to influence the engine power, an accelerator pedal (5) is provided as a setpoint generator. In a converter (7), the accelerator pedal position is converted into an electric signal which is supplied to the control unit (6). During the starting of the vehicle, a driving authorization control is carried out. The vehicle engine can already be started during the driving authorization control, but accelerator pedal position is taken into account by the control unit (6) only when the driving authorization control is concluded positively. This ensures both a reliable control of driving authorization and comfortable and reliable starting of the vehicle engine by an authorized driver.

Abstract: A magnetically sensitive sensor for counting pulses for measuring rotational speeds and angular positions of a rotating component via a pulse transmitter connected for rotating with the rotating component automatically adapts its switching points to the respective measurement location conditions. A logic unit initiates automatic adaptation of the switching points from an original state when an operating parameter first exceeds a limit value after the supply voltage of the sensor turned on. The original state is not preset or is coarsely preset. The configuration of the switching points is then stored in a non-volatile data memory specifically for the sensor.

By this means, molded parts with complicated shapes can be extracted, with particularly small structural requirements, from the casting mold.

Abstract: A device for measuring a fill level of a liquid includes an ultrasonic sensor with two sensor elements. One of the sensor elements determines the echo time of an ultrasonic wave to a float which follows the liquid level. The other of the sensor elements determines the echo time of the ultrasonic wave up to a measuring reflector arranged at a known distance from the other of the sensor elements. An evaluation unit compares the echo times and determines the fill level of the liquid from the ratio of echo times and from the known distance to the measuring reflector.

By this means, pollution of the environment with fuel is kept particularly low.

Abstract: A closure device, especially for vehicle doors, possesses a rotary latch interacting with a closure pin, a releasable ratchet for arresting the door, and a motor-driven shutting aid, which moves the door into the closed position. A problem from safety aspects is activating the shutting aid if fingers or articles are still located between the door and the bodywork. In order to reduce the risk of injury or damage, when the release mechanism is actuated, the force flow between the drive of the shutting aid and the door to be closed is simultaneously mechanically interrupted. As a result of this measure, the rotary latch is immediately released and the door springs open.

The level transmitter and the method are particularly suitable for use in fuel tanks in motor vehicles.

Abstract: An adjusting device serves for moving a moveable part into various positions, for example a side ventilator window of a motor vehicle. A servomotor (14) drives a spindle drive (18) which comprises essentially a spindle (24) having an external thread (26) and a sleeve part (28) which surrounds the spindle and has a corresponding internal thread (30). When acted upon by an external force, axial play in the region of the spindle drive (18) may lead to noise being produced; in order to avoid the noise, one (30) of the two threads comprises separate threaded parts (32, 36), and an elastically prestressable element (38) is provided with the aid of which an axial force can be produced between the two threaded parts (32, 36). The axial force causes the two threaded parts (32, 36) each to bear against opposite flanges of the external thread (26), so that the axial thread play is eliminated.
