Show Electric Device Controls Sprinters at Starting Line An electric device has been designed de-signed to prevent sprinters in track events from making false starts, says Collier's. It consists of a small box connected by wire to the starting gun and to a metal plate placed on the ground before be-fore each contestant. To make the electrical connection connec-tion that permits the gun to be fired, all runners must be in starting start-ing position and exerting a certain cer-tain pressure on the plate with both hands. |
