Patent ID: 6901801

Claim:
A capacitance acceleration derivative detector system comprising: a housing; a first plate fixed within said housing; a second plate fixed within said housing spaced apart from and in parallel relation to said first plate; a flexure plate disposed between and in substantially parallel relation to said first and second plates, said flexure plate coupled to said housing along at least an edge, said flexure plate and said first plate defining a first distance and said flexure plate and said second plate defining a second distance, wherein said first and said second distances vary in response to acceleration forces acting upon said flexure plate, and wherein said first plate and said flexure plate generate a first charge displacement capacitance signal, and said second plate and said flexure plate generate a second charge displacement capacitance signal; a first transimpedance amplifier receiving said first charge displacement capacitance signal and generating a first scaled voltage signal therefrom; and a second transimpedance amplifier receiving said second charge displacement capacitance signal and generating a second scaled voltage signal therefrom, wherein an acceleration signal is generated from said first scaled voltage signal and said second scaled voltage signal.
