发明名称 Improved Wireless Timing System
摘要 An improved wireless timing system shown in FIG. 1 comprising a means of transmitting wirelessly a signal ( 12 ) triggered by the reception of an electrical impulse from a timing event detector ( 11 ). The transmitter ( 12 ) being low power and thus short range to reduce cost, power consumption and interference with other timing systems. The individual or object being timed transports a portable timing unit ( 16 ), which could be in the form of a wrist watch, that is capable of receiving the wireless timing signal and calculating the passage of time between successive receptions of timing signals.
