    Abstract: A MEMS system including a fixed electrode and a suspended moveable electrode that is controllable over a wide range of motion. In traditional systems where an fixed electrode is positioned under the moveable electrode, the range of motion is limited because the support structure supporting the moveable electrode becomes unstable when the moveable electrode moves too close to the fixed electrode. By repositioning the fixed electrode from being directly underneath the moving electrode, a much wider range of controllable motion is achievable. Wide ranges of controllable motion are particularly important in optical switching applications.

    Abstract: A light-producing device integrated with a power monitoring system include a light-producing device from which light is emitted in wavelengths that can range from approximately 700 nm to approximately 3 microns. A semi-transparent sensor is located such that at least a portion of the light emitted passes through the semi-transparent sensor and at least a portion of light is absorbed by the semi-transparent sensor. The semi-transparent sensor is configured to be semi-transparent at wavelengths that can range from 700 nm to 3 microns. The semi-transparent sensor may also be used with an external light source, for example with fiber-optic cables.

    Abstract: A new type of high-Q variable capacitor includes a substrate, a first electrically conductive layer fixed to the substrate, a dielectric layer fixed to a portion of the electrically conductive layer, and a second electrically conductive layer having an anchor portion and a free portion. The anchor portion is fixed to the dielectric layer and the free portion is initially fixed to the dielectric layer, but is released from the dielectric layer to become separated from the dielectric layer, and wherein an inherent stress profile in the second electrically conductive layer biases the free portion away from the a dielectric layer. When a bias voltage is applied between the first electrically conductive layer and the second electrically conductive layer, electrostatic forces in the free portion bend the free portion towards the first electrically conductive layer, thereby increasing the capacitance of the capacitor.
