    • A clocked power supply is proposed which contains a fault current detection means (32) which evaluates a voltage drop occurring at an ohmic measuring resistor (25), and emits a switch-off signal (40) to a clocked voltage converter (5). The ohmic measuring resistor (25) is arranged in a line (24) of the clocked voltage converter (5) in which the alternating operating current of the clocked voltage converter (5) flows, the frequency of which alternating operating current is equal to the frequency of a switching signal (23) with which a circuit breaker (16) is operated. In order to suppress the portion of the voltage drop which can be tapped at the ohmic measuring resistor (25) and whose frequency corresponds to that of the switching signal (23), means, for example a low pass filter (33) and/or a parallel capacitor (26) which bridges the ohmic measuring resistor (25) are provided. The clocked power supply according to the invention is particularly suitable for operating gas discharge lamps (7) which are installed for example in motor vehicles, an effective protection of persons (30) against inadvertent contact with live components being provided.

    • In an arrangement for detecting pinching situations in electric drives, provided in particular for window and sunroof openers in motor vehicles, the voltage induced in the armature of the motor is used, the induced voltage being determined from the voltage across the motor terminals and the current flowing in the armature, in particular as the difference between the voltage across the motor terminals and the product of the armature current by the armature resistance which is obtained periodically whenever possible. The armature resistance is obtained from the voltage across the motor terminals and the blocking current of the motor, the latter being determined by extrapolation of the armature current determined at a certain point in time. The armature current is measured using a shunt resistor and optionally amplified, and the current signal obtained is averaged using a microcontroller-controlled integrator with adjustable, computed integration periods, and digitized using an analog-digital converter.

    • A method is presented for determining at least one end position of a displacement device (14) in a motor vehicle, wherein the displacement device (14) can be driven in the direction of its end positions and, in order to determine the particular end position, the displacement device (14) is driven to this end position and, on reaching this end position, the position of the displacement device is stored as representing the end position. Storage of the position of the displacement device of the particular end position takes place when the control variable of the displacement device has reached a particular predetermined value and/or has maintained this value for a predetermined period of time. This method is utilized in an advantageous manner to determine the end positions of a power actuator of an internal combustion engine of a motor vehicle.

    • A power-supply circuit having a switching regulator (10) and at least one additional circuit (14, 14') whose two respective outputs (11, 17) are guided together to a common or joint output (18) by diodes (D3, D3'; D4). The additional circuit (14, 14') produces, from an alternating quantity (15) occurring inside the switching regulator (10), a second output voltage (U+, U'+) that is in a second output-voltage range and is more positive with respect to the first output voltage (U-) that is made available at the first output (11) of the switching regulator (10) and is in a first output-voltage range. A gas-discharge lamp, for example, is provided as the load (L) between the first and second outputs. The division of the voltage ranges to be made available for the load (L) into at least two partial ranges permits a high effectiveness of the current-supply circuit of the invention.
