Abstract
Referee's wireless horn indicator system for aiding a referee in accurately officiating in a sports event. The system includes a controller and a sensory receiver. The controller includes the official time clock for the sports event, a control circuit coupled to the official time clock, and a radio transmitter activated by the control circuit for sending a radio signal to the sensory receiver. The sensory receiver is worn by the referee, for instance on the wrist, and includes a radio receiver and a sensory stimulating device such as a vibrator, both battery powered. Upon the official time clock reaching zero, a signal is sent by the transmitter to the radio receiver which then activates the sensory stimulating device to impart a tactual signal to the referee, thereby apprizing him of the expiration of the time period.
