Abstract
Abstract A device for measuring the speed of a person winte running along a surface is disclosed. A pressure switch or transducer (3) located in a shoe senses when a foot of the runner is in contact with the surface and produces a foot contact signal having a duration proportional to the time the foot is in contact with the surface. A radio frequency transmitter (1) is coupled to the pressure switch or transducer (3) and transmits the foot contact signal. A radio frequency receiver (4) receives the foot contact signal transmitted by the frequency transmitter (1) and a microprocessor (5) coupled to the radio frequency receiver (4) calculates, solely from the foot contact signal, an output speed signal representing the speed of the runner. A liquid crystal display (7) coupled to the output of the microprocessor (5) displays the speed of the runner in accordance with the output speed signal.
