Sporting equipment (tennis and table tennis bats) with electronic evaluation devices

摘要

In an item of sporting equipment (bat, racquet or stick of tennis, table tennis, badminton, indiaca, squash, hockey, ice hockey, polo or cricket), contact films are mounted at a point of impact which is defined according to the type of sport for the quantitative measurement of impacts, and display and count impacts by means of an electronic evaluation system in the handle or elsewhere. For the quantitative measurement of the force expended using the above items of sporting equipment, an extensometric strip is used as a variant at a point of impact to be defined for each type of sport and displays the force required, or the speed determined, via an electronic evaluation system which is situated in the bat handle or elsewhere. Evaluation can in each case be carried out either in a directly readable form or via further evaluating units. Both systems can be used for all types of bats used in sport, football boots and footwear used in all kinds of sport.
