摘要：The times which elapse while the participants in a race or another contest coverthe distance between a starting line and a finish line are ascertained, at an accuracy of onehundredth of a second, with a camera which takes pictures of the finish line at a firstfrequency and transmits picture signals to a pulse amplifier as well as to a mixing stagewhich latter transmits picture signals to a video recorder. A timing pulse generatortransmits 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 separatorconnected with the output of the amplifier of picture signals. This ensures that eachpicture receives and exhibits information denoting the exact instant of taking therespective picture irrespective of the frequency of picture taking. The timing pulsegenerator is started in response to firing of a starter gun, and the picture which is takenat or immediately after the time a contestant crosses the finish line further containsinformation denoting the exact instant of activation of a photoelectronic detector whichmonitors the finish line.
