<p>A system, automatically controlling a show-jumping tournament, has at least one circuit with starting and finishing lines. It consists of a first set of time measuring units coupled to starting and stopping units. The time setting units are set to a given time. There are comparators coupled to the time measuring and time setting units. A second set of time measuring units are coupled to the comparators to produce a time error used for stopping and starting the time measuring units.</p> |
