Clocking system for measuring running speeds of track runners
First Claim
1. A clocking system for measuring running speeds of a plural number of track runners at each one of a plural number of clocking positions provided at predetermined intervals along a running course or track toward a goal position, said clocking system comprising:
- an ID number transmitter carried by each runner and provided with an ID number generator to release at least an ID signal of said runner at each clocking position;
a trigger signal generator means provided at each one of said clocking positions to release a trigger signal toward said ID number transmitter of said runner passing across a measuring zone in front of said clocking position; and
time measuring means located at each one of said clocking positions to receive said ID signal transmitted by said ID number transmitter in response to said trigger signal from said trigger signal generator means, and arranged to register Identity of said runner passing across said clocking position along with a split time to said clocking position;
said ID number transmitter being arranged to release said ID signal repeatedly for a plural number of times in response to a trigger signal at predetermined time Intervals distinguishable of ID signals from other ID number transmitters carried by other runners.

Abstract
A clocking system for measuring running speeds such as split time or lap time for a plural number of track runners like racehorses at each one of a plural number of clocking positions provided at predetermined intervals along a running course or track toward a goal position. The clocking system fundamentally includes: a trigger signal transmission means provided at each one of the clocking positions and adapted to release a trigger signal toward a narrow signal receiving zone; a passing signal generating means carried by each runner and adapted to produce a passing signal specific to a particular runner at each clocking position upon reception of the trigger signal; and a measuring means provided either at each clocking position or on each runner and adapted to register a time reading for each runner upon reception of the trigger signal or passing signal. The measuring means can be arranged to include a sensor or a number of sensor means for collecting physical data of the runner during a run on an exercising track in addition to and in relation with the clocking operation.
