Patent ID: 8873029

Claim:
An integrated interferometric gyroscope and accelerometer device, the device comprising: a substrate comprising: a resonating cantilever beam; and an area that surrounds the resonating cantilever beam; a package comprising a resonating cavity collocated along an acceleration axis direction with the resonating cantilever beam; a driver incorporated within the resonating cantilever beam, the driver configured to electrothermally resonate the resonating cantilever beam; a sensor incorporated within the resonating cantilever beam, the sensor configured to sense a signal that relates to an acceleration force out-of-plane of the resonating cantilever beam; and a semiconductor interferometric optical gyro comprising an optical waveguide surrounding the resonating cantilever beam on the area of the substrate, the gyro being configured to sense rotational motion about an axis approximately equivalent to a vector corresponding to an acceleration force.
