    摘要： A method and an apparatus for current supply of an electronically commutated electric motor by a semiconductor power end stage are described, which has an arrangement for ascertaining the current received by the motor and an electronic controller for controlling the branch currents of the motor. For this purpose the electronic controller receives an input signal from a single current sensor (24) in a common conductor (26) of the semiconductor switches of the end stage, the terminal voltages (U1, U2, U3) of the individual branch windings (16, 18, 20) as well as the total voltage (U) applied to the end stage. From these input voltages and the input signal the electronic controller determines respective voltage drops at the individual semiconductor switches under logical incorporation of control signals (G1-G6) produced by the electronic controller. For the voltage drop at a particular semiconductor switch its respective conducting state D.C. resistance can be ascertained, so that additional current sensors in the individual branches for controlling the branch currents (I1, I2, I3) are not necessary.

    摘要： Disclosed is a seat adjusting device (10) and a method for operating the same. The seat adjusting device (10) includes two seat parts (15, 16, 17, 18, 19) positioned such that they are movable relative to each other and/or relative to a fastening surface (12, 14) and which are interconnected via at least one ratchet mechanism (56). The ratchet mechanism (56) includes a bidirectionally active rotary drive unit (54) which is operatively connected via a connecting element (52, 64, 72, 78) with at least one pneumatic linear actuator (52) which contracts in an axial direction when acted upon by a certain pressure (42, 43), which causes the rotary drive unit (54) to rotate.

    摘要： In a wiper system for vehicles, in particular for automobile windshields, including a first wiper arm, a primary drive motor (12) associated with the wiper arm for generating a defined wiping motion of the first wiper arm, at least one second wiper arm, and a secondary drive motor (13) associated with the second wiper arm for generating a defined wiping motion of the second wiper arm, the secondary drive motor (13) being controlled as a function of the position of the primary drive motor (12), a motor position code element (23) is provided, which is coupled to the primary drive motor (12) and is provided with control codes (24) that are directly representative of the associated position of the secondary drive motor (13). For scanning the control codes (24) of the motor position code element (23), a scanner unit (25) is used, which via a signal connection (22) is connected to a controller (27) of the secondary drive motor (13).
