FIELD: sport, medicine, engineering, transport. SUBSTANCE: known industrial instruments such as time interval velocity meter, electronic and electromechanical stopwatches registering time parameters with the help of electromechanical contact sensors are not applicable in majority of sports because of their overall dimensions, applied forces to them and supply of comparably high voltages. The offered reflexometer has two pulse generators flip-flop, two gates, synchronization element, pulse counter, indication unit, reset element, two switches, third gate has the fourth switch, transducer, voltage regulator. The third gate output is connected to the first input of the fourth gate, and its input is connected to the first transducer. The second input of the fourth gate is connected to the second transducer. Output of the fourth gate is connected to the first input of flip-flop. The second output of the second generator via the third switch is connected with the first output of the second generator and with second output of flip-flop. Voltage regulator output is connected with the first output of the first switch, with the second output of the second switch and the third output of the fourth gate. EFFECT: extended field of the application for registration of time parameters in majority of sports. |
