  • Inertial Sensor Mounting System
    Publication number: 20140013843
    Abstract: Embodiments of the present invention include various mounting systems (referred to herein as “carriers”) on which multiple matched inertial sensors (e.g., gyroscopes or accelerometers) can be mounted in a fixed, optimized arrangement that allows for multiple-axis sensing, while maintaining the position of the inertial sensors over the life of the product.

  • Process for etching patterned substrates
    Patent number: 5021120
    Abstract: A wet etching process wherein the etchant bath is ultrasonically vibrated, preferably while a carrier member holding the workpiece to be etched is slightly agitated. An apparatus for practicing the process includes a first vessel for holding a coupling fluid; a second vessel for holding an etchant solution; means for suspending the second vessel in the coupling fluid of the first vessel; and an ultrasonic generator means coupled to the first vessel to impart ultrasonic vibrations to the coupling fluid and, via the coupling fluid and second vessel, to the etchant solution.
