  • Publication number: 20080136614
    Abstract: A method and apparatus for detecting an automobile's window regulating status uses a window control switch and a central controller, which receives window regulating requests from the window control switch, sends instructions to windows concerned and makes queries to window motors concerned regarding each window's regulating status. If a concerned window fails to execute a relevant instruction correctly, the central controller actuates an alarm to send out an alarming signal.

  • Patent number: 7295894
    Abstract: To determine adjusting force comparison values for limiting the actuating force of a power-activated adjusting device by means of control technology, an initialization routine is predefined in a control unit, which allows the adjusting device to run through a specific number of complete adjusting cycles, before the recorded actuating force values are stored in the control unit as adjusting force comparison values.

  • Patent number: 7138783
    Abstract: The actuator and the method for operating the actuator comprise a drive unit and a drive mechanism with mechanical components that can be moved against each other as well as an electronic control unit. One of at least two components that can be moved against each other during operation acts as a switching transducer and initiates a switching operation in the event of relative movement in respect of a switching element, for example a Reed switch, caused by the action of an external force. This switching operation is used in the course of the control method to switch the control unit from a first operating mode to a further operating mode.
