French Abstract


PRECIS
On savait que ce n'est pas facile a déterminer la direction d'une
explosion avec les oreilles.
Jusqu'à présent , on utilise des appareils d'enregistrement d'une
explosion sans savoir sa direction.
Dans la présente d'invention , j'ai découvert un détecteur de directions
pour déterminer la direction d'une explosion. Par 4 capteurs de son dirigés
vers 4 directions différentes , ces capteurs transforment le son de l'explosion
en 4 signeaux de tensions. Ces tentions sont converties en digital , et
s'allument la barre LED. Le niveau de LED le plus élevé déterminera la
direction de l'explosion.

MEMOIRE DESCRIPTIF
1) La pré~ente lnventlon se rapporte à déterminer la direction d'une
oxplosion par un détecteur de directions.
2) Il est d'usage courant des microphones qui sont senslbles à une direction
c'est-~-dlre des microphones unldlrectlonelles. Ces mlcrophones uni-
dlrectlonelles ne peuvent détecter la direction d'une explosion.
3) J'al decouvert qu'en utllisant un microphone ~ 4 directions , on peut
d~terminer facllement la direction d'une explosion.
4) Pour déterminer la direction d'une explosion, l'utilisateur met correctement
ce detecteur dans les directlons Nord, Sud, Est, Ouest. Quand uneexplosion
arrlve , le nlveau de LED le plus élevé détermine la direction de l'explosion.
5) Référer à la figure 1 pour le schéma de principe de fonctionnement.
Référer à la figure 2 pour le schema de réalisation du détecteur de
directions.
