Abstract

Circuits servant à dériver des signaux inertiels de force spécifique et de vitesse angulaire pour un corps en mouvement provenant de plusieurs accéléromètres entrainés de manière cyclique. L'invention a trait, en particulier, à des circuits numériques destinés à produire des signaux numériques de force spécifique et de vitesse angulaire à partir d'une paire d'accéléromètres qui vibrent dans une direction perpendiculaire à leurs axes sensibles.
