A movement sensing structure is coupled to the mobile mass and detects the movement of the mobile mass in the sensing direction. A quadrature-injection structure is coupled to the mobile mass and causes a first and a second movement of the mobile mass in the sensing direction in a first calibration half-period and, respectively, a second calibration half-period. The movement-sensing structure supplies a sensing signal having an amplitude switching between a first and a second value that depend upon the movement of the mobile mass as a result of an external angular velocity and of the first and second quadrature movements. The first and second values of the sensing signal are subtracted from each other and compared with a stored difference value to supply information of variation of the scale factor. | 2022-08-11 |
20220252398 | ANGULAR VELOCITY SENSOR AND ANGULAR VELOCITY SENSOR SYSTEM - A controller applies a predetermined voltage to a fixed part detection excitation electrode to vibrate a movable part in a second direction and simultaneously applies a predetermined voltage to a fixed part drive electrode to vibrate the movable part in a first direction. The controller acquires, of the movable part, a first resonance frequency along the first direction and a second resonance frequency along the second direction. The controller controls a drive spring adjustment part to adjust a spring constant of the drive spring, such that the first resonance frequency is maintained constant, and controls a detection spring adjustment part to adjust a spring constant of the detection spring such that the second resonance frequency is maintained constant. The controller detects the angular velocity based on a result of synchronously detecting signal from the fixed part detection electrode with the first resonance frequency. | 2022-08-11 |
20220252399 | COMPOSITE SENSOR AND ANGULAR VELOCITY CORRECTION METHOD - A composite sensor includes an angular velocity sensor that detects angular velocity about three axes independent of one another, a first acceleration sensor that detects acceleration in directions of these three axes, a second acceleration sensor that is disposed at a position away from the first acceleration sensor and detects acceleration in a direction of at least one axis, and a computation unit that corrects the angular velocity detected by the angular velocity sensor based on the accelerations detected by the first acceleration sensor and the second acceleration sensor. | 2022-08-11 |
20220252400 | OPTICAL GYROSCOPE WITH A RESONATOR HAVING BIAS ERROR REDUCTION - Techniques for reducing the bias error present in optical gyroscopes is disclosed. Such techniques include at least one path length adjustment member placed in an optical gyroscope resonator, which are configured to modulate the optical path length of the resonator so that bias errors attributable to the optical path length are shifted outside of the bandwidth of the optical gyroscope. In some embodiments, the at least one path length adjustment member includes a plurality of microheaters coupled to the resonator, in which case optical path length modulation is achieved by heating the resonator via the microheaters. Alternatively, a plurality of piezo-electric regions can be placed in the resonator, which enables optical path length modulation through electric field gradients applied to the piezo-electric regions. | 2022-08-11 |
