Abstract:
1. An accelerometer system comprising: a housing; a flexure plate system enclosed within said housing and comprising a first fixed plate, a second fixed plate spaced apart from and in parallel relation to said first fixed plate, and a flexure plate disposed between and in substantially parallel relation to said first fixed plate and said second fixed plate, wherein all the flexure plate system is generated within said flexure plate, and wherein said first fixed plate and said second fixed plate receive reference signals; said flexure plate is rigidly fixed to said housing along at least an edge and electrically isolated from said housing, said flexure plate and the first fixed plate defining a first distance and a first capacitor and said flexure plate and said second fixed plate defining a second distance and a second capacitor, wherein said first and second distances vary in response to acceleration forces acting upon said flexure plate; a symbol generator generating a precision sine wave at a known phase angle; and a precision transformer receiving said precision sine wave and generating said reference signals therefrom.
