Gyro-sensor e.g. for vehicle navigation or CCD image stabilisation - has non-uniform gyro-mass with centre of gravity on gyro-axle held by bearings, one bearing connected to force or extension sensor also connected to mounting

摘要

The gyro-sensor includes a gyro-axle (KA), a gyro-mass (KM), and two bearings (L1,L2). The gyro-mass is non-uniform with its centre of gravity on the axle. The two bearings hold the gyro- axis while a motor is used to drive the axle. At least one of the bearings is connected to an extension or force sensor. The sensor is itself also connected to a mounting (H). The gyro-mass is in the form of a double club with uneven weight distribution. The force sensor includes a piezoelement, while the extension sensor is either a surface wave component or a deformable measurement strip. Phase-sensitive ac voltage measurement, e.g. lock-in measurement, is used for signalling the measurement results.
