Abstract

A race recording and display system includes a detection station for detecting each participant in a race. The detection station has an array of detection signal transmitting devices and identifying signal receiving devices arranged over a race course in sufficient numbers to irradiate a portion of the course ensuring detection and identification of each participant traversing the station. Detection results from the reflection of a portion of a detection signal transmitted by each transmitting device sufficient to provide an identifying signal unique to each participant to each receiving device. Identifying means carried by each participant provides the identifying signal upon irradiation by a detection signal. Determining means responsive to each identifying signal relates the identifying signal to each participant, fixes a time of receipt of the identifying signal and generates an information signal for transmission to a display means. The display means responds to the information signal by displaying information regarding the status of the race.
