Abstract (en)
[origin: US5105395A] The times which elapse while the participants in a race or another contest cover the distance between a starting line and a finish line are ascertained, at an accuracy of one hundredth of a second, with a camera which takes pictures of the finish line at a first frequency and transmits picture signals to a pulse amplifier as well as to a mixing stage which latter transmits picture signals to a video recorder. A timing pulse generator transmits signals at a frequency of one thousandth of a second; such signals are processed in a second generator which transmits processed signals to a pulse separator connected with the output of the amplifier of picture signals. This ensures that each picture receives and exhibits information denoting the exact instant of taking the respective picture irrespective of the frequency of picture taking. The timing pulse generator is started in response to firing of a starter gun, and the picture which is taken at or immediately after the time a contestant crosses the finish line further contains information denoting the exact instant of activation of a photoelectronic detector which monitors the finish line.
