ABSTRACT:
A microwave signal is generated from a fixed source across a fixed path to trigger individual FM transmitters in passing objects such as race vehicles. A vehicle transceiver then sends an omnidirectional specific frequency FM radio carrier signal with a tone imposed to a console and a portable remote receiver. As the FM signal and tone are detected and decoded by the console receiver, data word is sent to a scoring computer which displays the lap of that particular vehicle and the current order of all vehicles.
