Abstract: The invention relates to a method for operating an actuating drive having an electrically commutated motor 1 for adjusting an actuating member, having a position sensor 6 for detecting the rotary angle position of the rotor of the motor or of an element which can be driven in a rotatable manner by said motor. A motor control unit 9 serves to commutate the motor 1 and to regulate the position of the actuating member, it being possible to supply position signals, which correspond to the position values detected by the position sensor 6, to the motor control unit 9. After the actuating drive is started, uncompensated measured values are detected by the position sensor 6 over at least one full revolution of the rotor or of the element which can be driven in a rotatable manner; corresponding correction values for compensating angle errors are formed in a compensation unit 11.

Abstract: A limit-level sensor for measuring level of a liquid has a resistance element which has an electric resistance which suddenly varies a transition temperature which lies above the maximum liquid temperature. The resistance element is first of all heated by electric current. Thereupon, the electric resistance of the resistance element is measured. When the resistance element is covered with liquid, the heat generated by the electric current is led away so that the temperature of the resistance element is less than its transition temperature. If the resistance element is not covered by liquid, this heat is scarcely led away, so that the temperature of the resistance element remains above the transition temperature.

Abstract: A pump for a coolant circuit of an internal combustion engine of a motor vehicle includes a temperature sensor integrated into the pump for detecting the temperature of the fluid flowing into a pump chamber. The temperature sensor is inserted into a recess of a pump casing of the pump. The recess produces a reduced wall thickness (d) in the region proximate the temperature sensor. The reduced wall thickness improves the heat transition through the pump casing from the fluid to the temperature sensor and reduces the outlay in terms of production. Furthermore, the temperature sensor is arranged on a carrier material common to a control of the pump so that the susceptibility of the contacting of the temperature sensor to faults is reduced.

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.
