摘要： A micro-system, for example a micro-sensor, includes a resonator 10 with vibrating element(s) 11 receiving an excitation signal E of a loop 20 for automatic gain control, as a function of an amplitude setpoint (C) and providing as output a signal y(t) defined by a peak amplitude having a nominal value A0 dependent on the said setpoint and a resonant frequency. The micro-sensor integrates a circuit for measuring a quality factor of the resonator based on a measurement of an attenuation of the output signal during a momentary phase of cutoff of the excitation signal E applied to the resonator. This circuit for measuring the quality factor is configured so as to activate the excitation signal cutoff phase, for a duration of cutoff Td such that at the end of the cutoff phase, the peak amplitude of the output signal is attenuated by factor to the nominal peak amplitude A0 at the start of the cutoff phase, by a factor k with 1

摘要： A method for self-compensation of the bias draft of the quadrature signal of a gyroscope. The method is a combination of a variety of sub-methods, which can include quadrature compensation, can be used to achieve the highest possible stability. The calibration methods include a temperature self-sensing algorithm utilizing the drive-mode resonance frequency for calibration of thermal drift in the mechanical parameters of the system, a sideband-ratio approach for direct detection of mechanical drive-mode amplitude, modifying the AC and DC components of the amplitude gain control (AGC) for improved stability, and an approach for compensation of thermal drift in the sense-mode pick off system by utilizing mechanical quadrature. By using some or all of the four methods of calibration above, the highest level of long term in-run bias stability can be achieved.

摘要： A digitally-controlled oscillator circuit receives a digital value and generates a driving signal for driving an oscillator at a frequency according to the received digital value. A time-to-digital converter circuit receives a detection signal of oscillation of the oscillator, receives the driving signal, and detects a phase difference between the detection signal and the driving signal. A control circuit receives the detected phase difference and controls the frequency of the driving signal generated by the digitally-controlled oscillator circuit, such that the detected phase difference coincides with a predetermined resonant phase difference to resonate the oscillator.

摘要： An angular velocity detecting device which can estimate and detect correct mounting angles of a gyro sensor is achieved using outputs from the gyro sensor. The gyro sensor measures angular velocities in a sensor coordinate system and outputs them to an angular velocity calculating unit. A bias component removing unit of the angular velocity calculating unit carries out time average processing of the sensor coordinate system angular velocities, divides the sensor coordinate system angular velocities by time average values, and outputs them to a misalignment angle estimating unit. The misalignment angle estimating unit calculates, during a period in which a movable body is turning, a roll direction misalignment angle αφ using an angular velocity ωyse in a pitch angle θ direction and an angular velocity ωzse in a heading ψ direction in the sensor coordinate system. The misalignment angle estimating unit calculates a pitch direction misalignment angle Δθ using an angular velocity ωxse in a roll angle φ direction and an angular velocity ωzse in the heading ψ direction.

摘要： A Coriolis rate sensor for determining both angular rate and linear acceleration with respect to three orthogonal axes. A first embodiment of the rate sensor (10) includes three pairs of accelerometers (26, 28, and 30) mounted on counter-rotating frame members (20, 22). The accelerometers are mounted with their sensitive axes antiparallel with each other, forming an acute angle with the common axis (40) about which the upper and lower frame members are counter-rotated back and forth in a dither motion. The upper and lower frame members are connected to a baseplate (12) by flex links (32), which are aligned radially about the axis. The flex links provide a relatively rigid support (in compression) between the frame members and the centrally disposed baseplate, yet readily permit counter-rotation of the two frame members. A link (56) prevents all but relative rotational movement between the frame members and baseplate. A pair of electromagnetic coils (42) and pole pieces (50) provide a sinusoidal driving force to counter-rotate the upper and lower frame members relative to each other to ensure that the upper and lower frame members are directly coupled to each other and to the baseplate. In a second embodiment of the rate sensor (100), eight accelerometers (102, 104, 106 and 108) are mounted with two pairs on an upper counter-rotating member and two pairs on a lower counter-rotating member.
