ABSTRACT:
The described invention combines wireless transmission and reception technologies with athletic event timers to remove and reduce human and environmental factors that interfere with the athletic event timekeeping process for improvement of the process. The system controls and communicates the timing of a single athletic event between the timekeeping mechanism and the referee using at least one timing communicator with a transmitter and a channel selector. The transmitter is adapted to transmit a wireless electromagnetic radiation signal from outside the field of play to the field of play to a mobile field communicator having a receiver and channel selector also responsive to the channel selector. The mobile field communicator is adapted to be carried by the umpire or referee on the field of play and to receive the wireless signal from outside the field of play and emit an actuation signal in response thereto. The mobile field communicator and timing communicator channel selectors can be synchronized to produce the assignment of a unique address to allow the mobile field communicator and timing communicator to operate independently and securely without interference from other similar mobile field communicator and timing communicator devices in use within range of the system.
