  • Tire monitoring system
    Patent number: 6696935
    Abstract: A tire monitoring (TM) system includes a peak detector signal filter that is configured to substantially prevent impulse noise from increasing a data slicer threshold, while simultaneously allowing the data slicer threshold to follow the variations in a received message attributable to signal fading. The TM system also automatically determines the location of a plurality of vehicle tires relative to the vehicle, utilizes a single receiver to receive messages of multiple lengths and masks an alarm when a missing ID code corresponds to a stored ID code associated with a flat tire.
    Type: Grant
    Filed: September 10, 2001

    Assignee: Gentex Corporation
