Abstract

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.We knew that it is not easy to determine the direction of an explosion with the ears. Until now, we have used explosion recording devices without knowing its direction. In the present invention, I discovered a direction detector to determine the direction of an explosion. By 4 sound sensors directed to 4 different directions, these sensors transform the sound of the explosion into 4 voltage signals. These temptations are converted to digital, and light up the LED bar. The highest LED level will determine the direction of the explosion.

MEMOIRE DESCRIPTIF

1) La pré~ente lnventlon se rapporte à déterminer la direction d'une oxplosion par un détecteur de directions. `2QOgC ~

DESCRIPTIVE MEMORY

1) The pre ~ ent lnventlon relates to determining the direction of a oxplosion by a direction detector.

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. 2) Microphones which are sensitive to one direction are commonly used that is ~ ~ -dlre unldlrectlonelles microphones. These unified microphones Erectlonelles cannot detect the direction of an explosion.

3) J'al decouvert qu'en utllisant un microphone ~ 4 directions , on peut d~terminer facllement la direction d'une explosion. 3) I discovered that by using a microphone ~ 4 directions, we can easily determine the direction of an 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. 4) To determine the direction of an explosion, the user correctly sets this detector in the North, South, East, West directions. When an explosion arrlve, the highest level of LEDs determines the direction of the 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.
( 5) Refer to figure 1 for the operating principle diagram.
Refer to Figure 2 for the schematic diagram of the directions.
