Abstract

Avertisseur altimétrique, notamment pour parachutiste. L'avertisseur comprend, dans un boîtier 1, une platine 2 de capsule barométrique 20 avec une aiguille 25. A l'altitude choisie pour l'ouverture du parachute, la pointe réfléchissante 26 de l'aiguille passe devant un photocoupleur 30 qui amorce en réponse un thyristor 32 en série avec un vibreur 5, qui émet alors un signal sonore. Le thyristor 32 est désamorcé par mise en court-circuit par le bouton-poussoir 35. Ce bouton-poussoir 35 permet également de vérifier l'état des piles 40, 41 et du vibreur 5. L'altitude où est émis le signal sonore est réglée par pivotement de la platine 2 sous l'effet de la molette embrayable 45. Application au parachutisme.
