  • Patent number: 5963151
    Abstract: A passenger notification system to warn (bus) passengers of the next scheduled stop. A sensory indication which may be a verbal announcement or a lighted display (or both) within the bus is activated by the driver as each stop, transfer point or point of interest, approaches. A switch responsive to relative motion between the driver's upper arm and torso provides activation of a pre-recorded message in audio form from a sound transcriber. The lighted display is coded and activated from recorded signals. The sequence may easily be modified to fit each bus route.
