  • Patent number: 7586164
    Abstract: Micro-electro-mechanical system (MEMS) variable capacitor apparatuses, system and related methods are provided. According to one embodiment, a method for varying the capacitance of two conductive plates is provided. The method can include providing a micro-electro-mechanical system (MEMS) variable capacitor. The variable capacitor can include first and second actuation electrodes wherein one of the actuation electrodes is movable with respect to the other actuation electrode when a voltage is applied across the first and second actuation electrodes. Further, the variable capacitor can include first and second capacitive electrodes. The method can include applying a voltage to the first and second actuation electrodes for movement of at least one of the capacitive electrodes in a substantially straight direction with respect to the other capacitive electrode upon application of voltage across the first and second actuation electrodes to change the capacitance between the first and second capacitive electrodes.

  • Patent number: 6439050
    Abstract: An integrated circuit combines micro-machined elements, piezoelectric elements and signal processing components as part of a compensated oscillating gyroscopic sensor for angular motion detection. An oscillating mass is supported on a number of flexible beams micro-machined into an integrated circuit device, such as a silicon CMOS device. Several Piezo-electric elements, deposited on the beams, are provided to excite the mass and to measure the accelerations. Integrated in the device are electronic circuitry that initiates and maintains the oscillation and electronic circuitry that detects and measures the subsequent motion. Additional circuitry is also provided to eliminate the effects of quadrature oscillation and to determine the Coriolis acceleration and thus the magnitude of the external perturbing velocity.
