  • Patent number: 7197928
    Abstract: The present invention relates to a z-axial solid-state gyroscope. Its main configuration is manufactured with a conductive material and includes two sets of a proof mass and two driver bodies suspended between two plates by an elastic beam assembly. Both surfaces of the driver bodies and the proof masses respectively include a number of grooves respectively perpendicular to a first axis and a second axis. The surfaces of the driver bodies and the proof masses and the corresponding stripe electrodes of the plates thereof are respectively formed a driving capacitors and a sensing capacitors. The driving capacitor drives the proof masses to vibrate in the opposite direction along the first axis. If a z-axial angular velocity input, a Coriolis force makes the two masses vibrate in the opposite direction along the second axis. If a first axial acceleration input, a specific force makes the two masses move in the same direction along the first axis.

  • Patent number: 6928873
    Abstract: A silicon dual inertial sensor made of a (110) silicon chip comprises at least a proof-mass, which is connected to a corresponding inner frame with a plurality of sensing resilient beams to make it easier for the proof-mass to move perpendicular to the surface of the silicon chip (defined as z-axis), and each inner frame is connected to an outer frame with a plurality of driving resilient beams, or connected to common connection beams, which are then connected to a central anchor with common resilient supporting beams to make it easier for the inner frame to move in parallel with the surface of the silicon chip (defined as y-axis). Each inner frame is driven by a driver to move in an opposite direction along the y-axis, and also move the proof-mass in the opposite direction along the y-axis. If there is a rotation rate input along the x-axis, it will generate a Coriolis force to make each proof-mass move in the opposite direction of the z-axis.
