A micro-scale hemispherical resonator gyroscope includes a hemispherical resonator with a plurality of masses positioned around the periphery of the hemispherical resonator. At least some of the masses may be made of a heavy metal, such as tungsten, gold, ...

One exemplary embodiment is directed to a vibratory structure gyroscope having a substrate having a top surface. The vibratory structure gyroscope can also include a resonator having a hemitoroidal shape, the resonator including a stem and an outer lip tha...

The sensor has a single multiplexing unit (5) for control channels and detection channels. The multiplexing unit assures alternative demultiplexing of control signals and multiplexing of detection signals. The multiplexing unit is connected to a single pro...

The method involves measuring a component of anisotropy between detection electrodes (5.1, 5.2) that extend opposite to an edge (7) of a vibrating bell (1) of an inertial rotation sensor. The anisotropy is measured by measuring a gain difference between th...

The resonator has a fixed shell at a base (3) for carrying principal electrodes (5) extending from an edge of the shell. A protective electrode (6) is placed adjacent to the principal electrodes and is divided into two principal parts (6.1, 6.2) in the for...

The process involves exciting a vibrant device by combining control signals having an amplitude control signal, a rotation control signal around a gyroscopic axis and an amplitude modulated quadrature control signal. A vibration of the device is measured a...
