ABSTRACT:
An RF transponder transmits information on the distance traveled by a wheeled vehicle in response to an interrogation signal from an exciter/receiver. A rotation sensor, preferably an odometer/shaft encoder combination that is mounted on a vehicle wheel, provides to the transponder a signal which indicates the distance traveled by the vehicle; the transponder is also preferably mounted to the wheel's rotational hub. The transponder preferably includes a memory with a reprogrammable portion that stores the sensor information, and a non-reprogrammable portion that stores an identification code, all of which is read out in response to an interrogation signal. Driving distances can be obtained automatically without having to read the vehicle's dash board odometer.
