Abstract

Dispositif de détection de charge électrostatique. Le dispositif comprend une antenne A sur laquelle se développent les charges. Cette antenne A est reliée à la base d'un transistor 1 dont le collecteur est relié à un transistor amplificateur 2, dont le signal de sortie actionne une bascule monostable, à deux transistors 4 et 5, la durée de maintien en position instable étant déterminée par un circuit résistance 6, capacité 7.
