ABSTRACT:
In an on-board sensible signal that is activated by the speedometer of a vehicle when the vehicle speed exceeds a predetermined threshold and that remains activated when the speed is reduced below this threshold, the improvement consists of a combination of timing and logic circuitry that deactivates the signal when and only when the vehicle stops and remains at rest for a predetermined period of time.
