Abstract

a. Accéléromètre électrostatique. b. Cet accéléromètre comprend : des moyens montés pour pouvoir se déplacer d'une position neutre ou de repos le long d'un axe de mesure, en réponse à une accélération; des moyens qui en réponse au déplacement desdits moyens répondant à une accélération produisent un signal indiquant la direction du déplacement de ceux-ci; et deux éléments capacitifs disposés de part et d'autre desdits moyens répondant à une accélération afin de produire un signal indiquant l'amplitude et la direction du déplacement desdits moyens et pour forcer ces derniers à revenir à leur position neutre ou de repos. c. Concerne les instrument de mesure et plus particulièrement ceux mesurant les forces d'accélération.
