The invention called "TENNIS MASTER" constitutes one. suitable tool to determine if the tennis ball. as a result of the player's serve, he or she has fallen, even a few mm., beyond the contested line, diagonally opposite_ to the half of the court from behind which the serve itself was performed.

D E S C R IZ IO N E DESCRIPTION

Esso è costituito da 1) una unità centrale elettronica che elabora i segnali acustici di ogni battuta recepiti da un apposito microfono 2)sensori interrati fondo linea segnalanola posizione del giocatpre (destra/sinistra) It consists of 1) a central electronic unit that processes the acoustic signals of each beat received by a special microphone 2) underground sensors at the bottom of the line signal the player's position (right / left)

3) sensori situati in un piccolo canale intorno al perimetro della linea di servizio che stabiliscono se la palla ha toccato la linea o ha battuto dopo la stessa; 3) sensors located in a small channel around the perimeter of the service line that establish whether the ball has touched the line or has hit after it;

4) cellula fotoelettrica: attiva i sensori nel momento in cui' la palla lanciata in aria dal giocatore per effettuare la battuta, supera un’altezza di m 2,5; 4) photoelectric cell: activates the sensors when the ball thrown into the air by the player to take the serve exceeds a height of 2.5 meters;

5) timer per la misurazione del tempo.L’apparecchio_funzione captando il rumore creato dalla palla colpita dalla racchetta, al momento della battuta. 5) timer for measuring time. The device_function capturing the noise created by the ball hit by the racket, at the moment of the serve.

Se dall’ultima rumoreJ/unità centrale non riceve segnaii per 5 secondi, si attivano i sensoriposti a fondo linea per un tempo massimo di 3 secondi (poiché la palla non Impiegherà mai più di 3 secondi per arrivare nell’altra area). If from the last noise J / central unit does not receive signals for 5 seconds, the sensors placed at the end of the line are activated for a maximum time of 3 seconds (since the ball will never take more than 3 seconds to arrive in the other area).

Se però il giocatore non aspettasse 5 secondi i sensori verrebbero messi in funzione dalla fotocellula posta a fondo campo sulla testa del giocatore (più o meno 2,5 m), poiché per battere bisogna tirare la palla in alto almeno 2,5 m. However, if the player did not wait 5 seconds, the sensors would be activated by the photocell placed at the end of the field on the player's head (more or less 2.5 m), since to hit the ball must be thrown up at least 2.5 m.
