System for identifying and displaying data transmitted by way of unique identifying frequencies from multiple vehicles |
摘要 |
A system for detecting the location and identification of a number of vehicles at multiple points on a given track against a time gauge which includes an on-board transmitter on each vehicle of a unique identifying frequency, spaced receiving circuit elements along the track at multiple points connected to individual transmitters to receive and modify the identifying signal and transmit the signal to a programmed computer for translating the multiple signals of the different unique identifying frequencies into signals ascertainable on a portable hand apparatus selectively to indicate the speed of any selected vehicles as in a race, and to keep track of position standings and lap times.
