    摘要： A microcavity apparatus and systems for maintaining microcavity spacing over a macroscopic area. An application of this invention is a microscale generator. This microscale generator includes a first element for receiving energy; a second element, opposite the first element for transferring energy; at least one panel on either of the first element or the second element, the panel facing the other element; a device for controlling the distance between the at least one panel and the facing element to form a predetermined, sub-micron gap between the panel and the facing element for increasing energy transfer to the element for receiving; and a device, responsive to the energy transfer, for generating electricity.

    摘要： A micromechanical tuning fork gyroscope has an input axis out of the plane of the structure. In one embodiment, capacitor plates are provided in parallel strips beneath two apertured, planar proof masses suspended from a substrate by a support structure. The proof masses are paired and set in opposed vibrational motion by an electrostatic comb drive. In response to an input angular rate about the out-of-plane input axis, the proof masses translate with respect to the striped capacitors, thereby varying the capacitance between the capacitor strips and the proof masses as a function of the input rate. In another embodiment, proof mass combs of a comb drive are meshed between fixed drive combs which are electrically excited in pairs 180° out of phase. As the proof masses translate in response to an angular input, the distance between the proof mass combs and the fixed combs varies, thereby varying the capacitance between the combs resulting in an unbalanced voltage on the proof masses that is detected as an indication of input rate. The out-of-plane tuning fork gyroscope can be combined with two in-plane tuning fork gyroscopes to provide a complete three-axis inertial measurement unit from a single wafer or on a single chip.
