Abstract (en)
[origin: US4604621A] The electromagnetic transmission in an interference-laden environment of events defined by the time of their occurrence is accomplished by repeatedly generating, at equal intervals after occurrence of the event, signals representing the occurrence of the event. An event which must be defined by the time te at which it occurs triggers a switch which in turn triggers a time base whose signal is sent to a counter. The counter produces at its output a sequence of pulses which are coded in a coder. The code indicates for each pulse the deviation in time DELTA Ti which separates it from the time at which the event occurred. The sequence of pulses is sent electromagnetically to a receiver via a transmitter. The first interference-free pulse received is processed by a decoder which provides the value DELTA Ti to an arithmetic unit. The arithmetic unit subtracts the value DELTA Ti from the time of day th to obtain the time of day te of the event. The device is applicable in particular to the timing of sporting events.
