Abstract: There is disclosed a glove employing an adjustable pressure sensitive means for use by contestants engaged in a karate contest. The glove assures that each contestant is associated with a given strike frequency. The gloves provide the strike frequency which will be transmitted when the contestant strikes a blow of sufficient force. Each glove is associated with a transmitter operating at a selected strike frequency and a pressure sensitive area which causes the transmitter to transmit the strike frequency. Also associated with each contestant is another pressure sensitive area which is a target area. When this area is struck by an opponent, a target frequency is transmitted. In order to determine that a valid blow was rendered, a receiver is incorporated and employed by a judge. The receiver will respond to two frequencies to determine whether a valid blow has been struck. The receiver must receive a first frequency indicative of the strike frequency and a second frequency indicative of the target frequency.
