US Patent 7339478 Method and apparatus for remote control vehicle identification

An apparatus and method for automatically tracking each individual vehicle, of a plurality of vehicles, in a race around a track. The device employs RFID tags on each of the vehicles being tracked. The device employs RFID tags and a gate to energize the tag to broadcast the vehicle's identity when a pass through the gate is determined. The device can be employed to both track the individual vehicle participants in a race, and to register the participants before the race. Races can be tracked on different courses in different geographic locations by placing the RFID tags on all participants and tracking their progress on the individual remote tracks from a central location.
