Abstract

The arrangement uses electret microphones at intervals along the bands which define the court lines. When a ball strikes the line, the microphones detect the shock, and send a signal to an amplifier unit. The amplifier is arranged to produce an audible and a visual signal in response to this. Variable resistors are provided in the court unit to adjust the sensitivity of the microphones. The amplifiers are interchangeable and are powered by a single unit. An indicator light is provided to show a malfunction in the system.

Description

La présente invention concerne les aires de terrains de sport notamment les courts de tennis. The present invention relates to areas of sports grounds, in particular tennis courts.

L'invention permet à l'arbitre de jeu de savoir si la balle à frappé ou non les bandes qui délimitent les courts de tennis. The invention enables the game referee to know whether or not the ball has struck the strips which delimit the tennis courts.

L'invention à pour objet un système de contrdle électronique sonore et visuel pour contr8ler les balles litigieuses venant frapper les bandes qui délimitent les courts de tennis. The invention relates to an electronic sound and visual control system for controlling the disputed balls hitting the strips which delimit the tennis courts.

Le système de contrôle s'adapte exclusivement sur les bandes de mon invention brevet nO 8102063 Fig 1 et Fig 4 (lu)
La solution à pour but de placer des pastilles microphones (éléctret) Fig 2(lu) et Fig4 (lob) placées sous les bandes qui délimitent les courts de tennis, pour les placer il faut enlever une partie de l'aile verticale de la bande Fig 1 (nid) , les pastilles microphonnes sont reliées par cable à des amplificateurs Fig 3 (le);;
Un amplificateur est conposé de Fig 3 transistors ampli-micro (if) , des transistors commandes diodes (1h) , un ou plusieurs (1K) potentiomètres de réglage de sensibilité , des résistances , des composants électronique (1m)
Les amplificateurs sont reliés par cable à un tableau d'affichage sonore et visuel
Le tableau d'affichage Fig 5 est composé de diodes , lorsque la balle frappe la bande un secteur de diodes s'éclaire
Tout le système de contrle est alimenté par un boitier électrique Fig 4 (la) qui relie par cable les pastilles microphonnes les amplificateurs , le tableau d'affichage
Tout le cablage est placé sous les bandes oui délimitent les courts de tennis.The control system fits exclusively on the strips of my invention patent no. 8102063 Fig 1 and Fig 4 (read)
The solution aims to place microphone pads (electret) Fig 2 (lu) and Fig4 (lob) placed under the bands which delimit the tennis courts, to place them you must remove part of the vertical wing of the band Fig 1 (nest), the microphonets are connected by cable to amplifiers Fig 3 (le) ;;
An amplifier is made up of Fig 3 ampli-micro transistors (if), diode control transistors (1h), one or more (1K) sensitivity adjustment potentiometers, resistors, electronic components (1m)
Amplifiers are connected by cable to a sound and visual display board
The display board Fig 5 is composed of diodes, when the ball hits the strip a sector of diodes lights up
The entire control system is powered by an electric box Fig 4 (la) which connects by microphones pads the amplifiers, the display board
All the wiring is placed under the strips yes delimit the tennis courts.

Un voyant lumineux Fig 5 (lz) permet de détecter tout composant défaillant
Sur un court de tennis un secteur est défini Fi 4 (ly) par plusieurs longueurs de bandes , chaque bande comprend plusieurs pastilles microphonnes et un secteur comprend un oy plusieurs amplificateurs
Le système ae contrôle étant réglable en sensibilité par les potentiomètres de sensibilité , le poids du joueur (pied) sur les bandes ne donne pas de signal sur le tableau d'affichage
Le choc de la balle sur la bande produit un son , un choc que la pastille microphonne enregistre puis transmis à l'amplificateurs qui à son tour le transmets au tableau d'affichage
L'invention ne se limite aucunement à celui de ses modes d'application non plus qu'a ceux des modes de réalisation de ses diverses parties ayant plus spécialement été indiquées ; elle en embrasse au contraire toutes les variantes An indicator light Fig 5 (lz) can detect any faulty component
On a tennis court a sector is defined Fi 4 (ly) by several lengths of bands, each band includes several microphones and a sector includes one or more amplifiers
The control system being adjustable in sensitivity by the potentiometers of sensitivity, the weight of the player (foot) on the bands does not give a signal on the display board
The shock of the bullet on the tape produces a sound, a shock that the microphone pad records and then transmits to the amplifiers which in turn transmit it to the bulletin board
The invention is in no way limited to that of its modes of application any more than to those of the embodiments of its various parts which have been more particularly indicated; on the contrary it embraces all variants
