MICROMECHANICAL VIBRATION GYROSCOPE Russian patent published in 2013 - IPC G01C19/56 

FIELD: measurement equipment.

SUBSTANCE: gyroscope comprises a disc fixed with the help of an elastic suspension and a setting plate, an excitation torque sensor, two capacitance angle sensors, designed for measurement of disc oscillations around axes, normal axes of torsion oscillations (output axes of the gyroscope), two compensatory torque sensors. The excitation torque sensor has printed windings on the disc surface with radially aligned rectilinear sections, which are in the magnetic field, formed by permanent magnets fixed in the gyroscope body, having opposite poles facing the disc. Spiral printed windings of compensatory sensors are in the magnetic field formed by permanent magnets fixed in the gyroscope body, having identical poles facing the disc. The gyroscope also comprises a control system, making it possible to maintain constant angular speed of disc torsion oscillations, a feedback system, compensating oscillations of the disc around output axes.

EFFECT: possibility to adjust quadrature components of a gyroscope signal.
