Abstract

A system and a process for determining the timing and position of contestants on a track. This system comprises at least one set of two trapezoidal shaped loops that have a longitudinal axis that project from an inside rail to an outside rail on the track. There is also at least one competitor communication device that can be coupled to each contestant. A remote base station, is in communication with the positioning device, wherein the positioning device determines a contestant time as the contestant passes the wire loop and also determines the position of the contestant in relation to an inside guide such as a rail. A relay positioned in the center of the track can also be used to increase the signal flowing between the base station and the positioning device. The process for determining the position and timing of each contestant in a race includes the steps of attaching at least one competitor communication device on at least one individual contestant. Next, the race starts, whereby during the race, the position and time for each contestant is recorded. Next a signal is transmitted from the competitor communication device to a remote base station. Finally, these signals are synchronized so that there is no interference.
