    摘要： Single chip 3-axis thermal accelerometer devices include a substrate, at least one cavity etched in the substrate, a fluid disposed in the cavity, a bridge structure suspended over an opening of the cavity, and a plurality of heater elements and temperature sensing elements disposed on the bridge structure. The substrate has a substantially planar surface defined by X and Y coordinate axes, and the bridge structure is suspended over the opening of the cavity in the X-Y plane. In one embodiment, the bridge structure is configured to position at least two of the temperature sensing elements out of the X-Y plane. The heater and temperature sensing elements are disposed on the bridge structure in optimized arrangements for providing reduced temperature coefficients and for producing output voltages having reduced DC offset and drift.

    摘要： A thermal accelerometer device that provides a compensation for sensitivity variations over temperature. The thermal accelerometer includes signal conditioning circuitry operative to receive analog signals representing a differential temperature is indicative of a sensed acceleration. The signal conditioning circuitry includes serially connected A-to-D and D-to-A converters, which implement a temperature dependent function and process the received signals to provide a compensation for sensitivity variations over a range of ambient temperature. To provide a ratiometric compensation for variations in power supply voltage, a buffered voltage proportional to the supply voltage is provided as a reference voltage to the D-to-A converter. The thermal accelerometer includes a self-test circuit for verifying the integrity of a heater, temperature sensors, and circuitry included within the device.

    摘要： A laser, direct-write system for making personalized custom or semi-custom integrated circuits with a very fast turnaround time. The system includes a method and apparatus for high percision scanning of a submicron laser spot. The laser beam is scanned at the entrance of a beam expander. The beam expander reduces the scan angle and error produced by a mechanical scanning device such as a rotating polygonal mirror. The smaller scan angle at the output of the beam expander matches well with the projection optics of a laser, direct-write semi-custom integrated circuit production system. The scan error reduction permits more accurate positioning of the focussed laser spot on the surface of the semi-custom integrated circuit.

    摘要： Techniques for reducing false recalls by controlling recalls performed by data migration applications in a storage environment comprising a plurality of storage units. According to an embodiment of the present invention, false recalls are reduced by restricting certain users, groups, and programs from performing recall or demigration of data. Techniques are provided that enable a storage system administrator to specify a list of users, groups, and programs for which data file recall is disallowed.
