  • Patent number: 8644791
    Abstract: A communications module apparatus for an automotive network comprises an input for receiving data to be transmitted. The apparatus also comprises a first output for coupling to a first bus line and a second output for coupling to a second bus line. An alternating voltage signal transmission circuit for transmitting at least part of the received data is also provided. The alternating voltage signal transmission circuit is coupled to the first output and the second output.
    Type: Grant

  • Patent number: 6812589
    Abstract: The present invention describes a circuit for activating a control unit such as an ABS controller in a vehicle by way of a CAN bus, with the ignition turned off, which is in particular characterized by a first input for a logic activation signal for the control unit, an input filter for suppressing disturbing pulses in the activation signal, and a device for producing an output signal (CAN_WU) that activates the control unit when a predeterminable number of activation signals is recorded within a predeterminable duration.

  • Patent number: 6552531
    Abstract: The present invention relates to a method and a circuit arrangement for processing signals for an active motion sensor which generates at least one first sequence of input pulses that contain motion information. By at least one integrating filter circuit, each input pulse of a pulse train is integrated, and an associated output pulse is generated during a period in which the integrated signal is in excess of a predeterminable second threshold value after a predeterminable first threshold value has been exceeded so that the output pulse has a time delay with respect to the input pulse. As a result, noises of a duration which is shorter than the delay time are effectively suppressed.
