|20120106591||Overhead Power Connector Integrity Assessment by Application of Thermal History Detectors - Systems and methods for monitoring the integrity of an overhead power connector are disclosed. The systems and methods may include applying a temperature sensitive material to at least a portion of an overhead power connector and/or an overhead power conductor. The integrity of the overhead connector may be monitored or diagnosed by monitoring the properties of the temperature sensitive material to determine if the overhead connector experienced any high temperature excursions.||05-03-2012|
|20110038492||OPTICAL SENSING IN A DIRECTIONAL MEMS MICROPHONE - A microphone having an optical component for converting the sound-induced motion of the diaphragm into an electronic signal using a diffraction grating. The microphone with inter-digitated fingers is fabricated on a silicon substrate using a combination of surface and bulk micromachining techniques. A 1 mm×2 mm microphone diaphragm, made of polysilicon, has stiffeners and hinge supports to ensure that it responds like a rigid body on flexible hinges. The diaphragm is designed to respond to pressure gradients, giving it a first order directional response to incident sound. This mechanical structure is integrated with a compact optoelectronic readout system that displays results based on optical interferometry.||02-17-2011|
|20090266162||BULK ACOUSTIC WAVE GYROSCOPE - Capacitive bulk acoustic wave x, y and z-axes gyroscopes implemented on (100) and (111) silicon substrates are disclosed. Exemplary gyroscopes comprise a handle substrate, a bulk acoustic wave resonator element supported by the handle substrate, and a plurality of electrodes surrounding and separated from the resonator element by very small capacitive gaps. The electrodes can excite and detect at least two degenerate bulk acoustic wave resonant modes in the resonator. Advantages include reduced size; higher Q, which improves noise and bias stability; larger bandwidth, and improved shock resistance. In addition, the high Q is maintained in atmospheric or near-atmospheric pressure which reduces the cost and complexity of the wafer-scale packaging of the gyroscope.||10-29-2009|
