  • Middle layer of die structure that comprises a cavity that holds an alkali metal
    Publication number: 20080000606
    Abstract: An apparatus in one example comprises a die structure that comprises a middle layer, a first outside layer, and a second outside layer. The middle layer comprises a cavity that holds an alkali metal, and one of the first outside layer and the second outside layer comprises a channel that leads to the cavity. The middle layer, the first outside layer, and the second outside layer comprise dies from one or more wafer substrates.

  • NMR gyroscope
    Publication number: 20060139029
    Abstract: An NMR gyroscope in one example comprises a support structure affixed within an enclosure, an NMR cell affixed to the support structure, a plurality of permanent magnets disposed about the NMR cell to produce a magnetic field within the cell, and a field coil disposed proximate the cell to produce a modulated magnetic field transverse to the magnetic field produced by the permanent magnets.

  • Micro-cell for NMR gyroscope
    Publication number: 20060132130
    Abstract: A cell in one example comprises an alkali metal and a coating of parylene on an interior surface of the cell. In one implementation, the alkali metal may be an optically pumped gaseous phase of an alkali metal. The parylene coating minimizes interaction of the excited state of the alkali metal, increases lifetime of the excited state, and minimizes interaction of nuclear spin states with the cell walls.

  • Photo-detector and related methods
    Publication number: 20060125068
    Abstract: An apparatus comprising at least one multilayer wafer includes a device layer adjacent to a barrier layer, and the device layer includes at least two photoconductive regions separated by an etched channel extending through the device layer. In some instances the apparatus may be an accelerometer having two photodiodes formed on a silicon-on-insulator (SOI) wafer with the photodiodes defined by one or more etched channels extending through the device layer of the SOI wafer. Also disclosed are methods for forming such an apparatus.

  • Dissipation of a charge buildup on a wafer portion
    Patent number: 7038293
    Abstract: An apparatus in one example comprises a wafer portion that comprises a conduction layer. Upon exposure of the conduction layer during a etch of the wafer portion, the conduction layer serves to dissipate a portion of a charge buildup on the wafer portion during an etch of the wafer portion.
