    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: A leveling system for a missile system includes a holder defining an xz-plane. Four flexure plate accelerometers are coupled to the holder at angles such that they are sensitive to movement in an xy-plane. The accelerometers all generate signals in response to movements of the flexure plates. An actuator activates an object control device in response to a platform control signal. A processor receives the accelerometer signals and generates the platform control signal in response thereto.

    摘要: A capacitance accelerometer includes a housing, and a plate fixed within the housing. A moveable plate is disposed in substantially parallel relation to the fixed plate and is coupled to the housing along at least an edge. The moveable plate and the fixed plate define a distance. The distance varies in response to acceleration forces acting upon the moveable plate, and wherein the moveable plate and the fixed plate generate a charge displacement capacitance signal. A transimpedance amplifier receives the charge displacement capacitance signal and generates a scaled voltage signal therefrom. An acceleration signal is generated from the scaled voltage signal.

    摘要: A capacitance acceleration derivative detector includes a housing, and a first plate fixed within the housing. A second plate is also fixed within the housing and spaced apart from and in parallel relation to the first plate. A flexure plate is disposed between and in substantially parallel relation to the first and second plates. The flexure plate is coupled to the housing along at least an edge. The flexure plate and first plate define a first distance and the flexure plate and the second plate define a second distance. The first and second distances vary in response to acceleration forces acting upon the flexure plate. The flexure plate and the first fixed plate generate a first charge displacement capacitance signal, and the second fixed plate and the flexure plate generate a second charge displacement capacitance signal. A first transimpedance amplifier receives the first charge displacement capacitance signal and generates a first scaled voltage signal therefrom, and a second transimpedance amplifier receives the second charge displacement capacitance signal and generates a second scaled voltage signal therefrom. An acceleration signal is generated from the first scaled voltage signal and the second scaled voltage signal.

    摘要: A flexure plate accelerometer system includes a flexure plate and two fixed plates on either side of the flexure plate. The flexure plate generates a flexure plate signal as a function of reference signals received in the fixed plates. A precision transformer generates the reference signals from a precision sine wave generated by a symbol generator controlled by a microprocessor. The microprocessor controls the symbol generator and activates an analog-to-digital converter in response to a signal coincident with a positive and negative peak of the precision sine wave. The analog-to-digital converter generates a digital word from the flexure plate signal, which is processed further in the microprocessor.

    摘要: A compass device includes a platform defining an xz-plane and an x-axis. A first accelerometer is coupled to the platform at an angle such that the first accelerometer is sensitive to movement of the first accelerometer in the xz-plane. The first accelerometer includes a first flexure plate generating a first accelerometer signal in response to movement of the first flexure plate. A second accelerometer is coupled to the platform at an angle such that the second accelerometer is sensitive to movement of the second accelerometer within the xz-plane. The second accelerometer includes a second flexure plate generating a second accelerometer signal in response to movement of the second flexure plate. A processor receives the first accelerometer signal and the second accelerometer signal and generates a platform control signal, thereby rotating the platform in response to an inequality between the first accelerometer signal and the second accelerometer signal.

    摘要: An accelerometer includes an inertial platform maintaining an attitude in response to a platform stabilizing controller signal and defining a spin axis and a reference plane. An accelerometer, coupled to the inertial platform a distance from the spin axis, defines a flex axis. The accelerometer generates an accelerometer signal in response to acceleration of the accelerometer. A second accelerometer defines a second flex axis, and is also coupled to the inertial platform a distance from the spin axis. The second accelerometer generates a second accelerometer signal in response to acceleration of the second accelerometer. A controller receives the first accelerometer signal and the second accelerometer signal and generates a linear acceleration signal in response to a sum of the first accelerometer signal and the second accelerometer signal and generates an angular acceleration signal from the difference. The controller further generates the platform stabilizing controller signal in response to the first acceleration signal and the second acceleration signal.
