    摘要: A method for constructing a compensated composite structure, including a support tube coupled to a flexure plate and enclosing a capacitor plate, includes selecting a material for the support tube whereby the coefficient of expansion is larger than that of the material of the capacitor plates. Further, the method includes selecting the lengths of the support tube and the capacitor plate such that the composite structure is insensitive to changes in temperature.

    摘要: An accelerometer system includes a capacitor plate fixed within a housing and a flexure plate positioned substantially parallel to the capacitor plate a distance therefrom. The distance varies in response to acceleration forces acting upon the flexure plate such that the flexure plate and the capacitor plate generate a capacitance signal. A magnet is coupled to the flexure plate and generates a magnetic field, which moves as the flexure plate flexes. A coil winding around the flexure plate generates a second magnetic field as a function of capacitance signal, thus opposing the flexure plate magnetic field, and thereby returning the flexure plate to a null position.
