APPARATUS FOR DETERMINING SPORTSMAN'S JUMP LENGTH Russian patent published in 1998 - IPC

FIELD: sports equipment. SUBSTANCE: apparatus has block with equally spaced radiation sources, block with radiation receivers positioned in spaced relation one relative to another, with space and number of radiation receivers being equal to that of radiation sources. Each radiation receiver is positioned opposite to related radiation source to define optoelectronic couple. Apparatus is further provided with block of threshold elements connected to block of radiation receivers, computer, whose input is connected to set value recorder and output is connected to indicator, sync generator, optoelectronic couple address forming block, radiation source control block and signal commutator. Sync generator is connected to input of optoelectronic couple address forming block, whose outputs are connected to radiation source control block, control inputs of signal commutator and to second inputs of computer. Radiation sources are connected to outputs of radiation source control block. Inputs of signal commutator are connected to outputs of threshold elements block and output is connected to third input of computer. Apparatus may be further provided with radiation source block, radiation receiver block, threshold elements block and signal commutator, which are similar to main mentioned blocks. EFFECT: increased efficiency and enhanced reliability in operation. 2 cl, 2 dwg
