Abstract: Systems and methods are disclosed herein for extracting system parameters from nonlinear periodic signals from sensors. A sensor such as an inertial device includes a first structure and a second structure that is springedly coupled to the first structure. The sensor is configured to generate an output voltage based on a current between the first and second structures. Monotonic motion of the second structure relative to the first structure causes a reversal in direction of the current.

Abstract: A vibratory gyroscope system is described which utilizes a mechanical resonator having a first mode of vibration and an associated first natural frequency, and a second mode of vibration having an associated second natural frequency. The angular rate of motion input couples energy between the first and second modes of vibration. The gyroscope has driver circuits, sensors and actuators for the first and second modes. The invention utilizes a bias error shifting method which provides for shifting the bias error away from DC to a higher frequency, where it can be removed by low pass filtering. As a result of the inventive method, gyroscope systems can be produced with significantly lower bias error.

Abstract: Provided herein is a method for determining a bias-compensated inertial rotation rate of a Coriolis vibratory gyroscope (“CVG”). The method comprises determining an initial mode that the CVG is operating; obtaining average uncompensated inertial rotation rate measurements from a previous mode transition period; obtaining average uncompensated bias measurements from the previous mode transition period; determining a first transition between a AGC mode and a FTR mode of a given axis; calculating a first estimate of bias of the CVG based on the first transition that was determined and the average uncompensated bias measurements from the previous mode transition period; and calculating, by a processor, a first bias-compensated inertial rotation rate of the CVG based on the first bias that was calculated and the average uncompensated inertial rotation rate measurements from a previous mode transition period.

Abstract: A system includes a circular oscillator suspended by a flexible support structure to a support frame, a drive mechanism configured to induce the circular oscillator into a two-dimensional drive oscillation, where the drive oscillation is modified responsive to a sense oscillation of the circular oscillator caused by an angular rotation of the support frame and the circular oscillator, and a plurality of digital proximity switches disposed around a perimeter of the circular oscillator. During the modified drive oscillation a plurality of the digital proximity switches are configured to switch between an open state and a closed state and generate a time and position output to allow for a determination of each of a plurality of variable oscillation parameters for each oscillation of the modified drive oscillation.

Abstract: A vibration gyro having a structure for canceling a quadrature error generated by structural asymmetricity due to production tolerance and a means for correcting a bias value when an angular velocity is zero. In order to apply a counter torque to a sense mass for canceling the quadrature error, left correction comb electrodes are fixed to a substrate adjacent to a left drive mass, and comb electrodes opposed to the correction comb electrodes are arranged on an inner portion of a frame member which constitutes the left drive mass. By applying DC voltage to the correction electrodes, electrostatic force, for canceling the leakage rotational displacement of the sense mass generated when the input angular velocity is zero, is generated.
