Title (EN) DEVICE FOR MEASURING AT LEAST ONE PHYSICAL PARAMETER RELATING TO A PROPELLED GAME BALL
(FR) DISPOSITIF DE MESURE D'AU MOINS UN PARAMETRE PHYSIQUE RELATIF A UNE BALLE DE JEU PROPULSEE
Abstract:
(EN) A device (1) for measuring the strike velocity of a game ball struck by a striking element, particularly a tennis racket (2), said device being provided directly on the racket. The device comprises at least one measuring sensor mounted on the strings (4) of the racket (2) and arranged to output signals for the strength of the vibrations generated by the ball, means for processing said signals using microprocessors that analyse the signals and determine a measured value of the ball velocity, and means (6) for displaying said value. The processing means comprise a calibrating unit for automatically correcting the measured value depending on at least the features of the racket and the ball in order to provide a highly accurate and reliable result. Said measuring device is miniaturised and inexpensive and fits in a small housing (3) mounted on the racket (2) to enable the player to read the velocity value directly. The device is useful in any sport or game involving a projectile and a striking element, particularly in tennis.
(FR) La présente invention concerne un dispositif de mesure (1) de la vitesse de frappe d'une balle de jeu propulsée au moyen d'un organe propulseur, notamment d'une raquette de tennis (2), ce dispositif étant prévu directement sur la raquette. Il comporte au moins un capteur de mesure monté sur le cordage (4) de la raquette (2) et agencé pour délivrer des signaux correspondant à l'intensité des vibrations engendrées par la balle, des moyens de traitement de ces signaux par des microprocesseurs agencés pour les analyser et déterminer une valeur mesurée de la vitesse de la balle et des moyens d'affichage (6) de cette valeur. Les moyens de traitement comportent une unité de calibrage qui permet de corriger automatiquement la valeur mesurée en fonction au moins des caractéristiques de la raquette et de la balle pour obtenir un résultat très précis et fiable. Ce dispositif de mesure est miniaturisé et peu coûteux. Il tient dans un petit boîtier (3) monté sur la raquette (2) et permettant une lecture directe de la valeur de la vitesse par le joueur. Applications: tout sport et jeu faisant intervenir un projectile et un organe propulseur et notamment le tennis.
