  • Patent number: 7262522
    Abstract: A microelectromechanical system (MEMS) device is used to transfer power from a source generator to a power generator that delivers electrical power to a load, while maintaining electrical isolation between the source generator and power generator for size critical applications where transformers or coupling capacitors would not be practical, but where electrical isolation is desired.
    Type: Grant

  • Patent number: 7093498
    Abstract: A microelectromechanical system (MEMS) strain gauge includes at least one flexible arm that can be caused to oscillate. Transverse strain on the arm changes the resonant frequency of the arm. A detector communicating with the flexible arm may detect the frequency of oscillation to provide, an indication of the transverse strain of the substrate.

  • Patent number: 6975193
    Abstract: Microelectromechanical (MEMS) switches are used to implement a flying capacitor circuit transferring of electrical power while preserving electrical isolation for size critical applications where transformers or coupling capacitors would not be practical. In one embodiment, the invention may be used to provide input circuits that present a programmable input impedance. The circuit may be modified to provide for power regulation.

  • Patent number: 5271284
    Abstract: A body ply splice width monitor is provided to sense the leading and trailing edges of a lateral splice in a web of tire body ply material and to produce an indication upon a monitor as to whether such splice satisfies certain dimensional criteria. A first pair of sensors is maintained along one edge of the web, while a second pair of sensors is maintained along the opposite edge. An encoder tracks the movement of the web through the array of sensors and provides output pulses corresponding to finite dimensional lengths of the web. The number of pulses between the sensed leading edge and sensed trailing edge of the splice is used to indicate and determine the total splice width.

  • Patent number: 4735662
    Abstract: A stable ohmic contact for thin films of p-type tellurium-containing II-VI semiconductors and photovoltaic devices incorporating such contacts. An ohmic contact according to the invention includes a contact-forming layer deposited on a p-type thin film of a tellurium-contacting II-VI semiconductor. Preferably, the contact-forming layer is copper having a thickness of about 2 nanometers. An isolation layer is deposited on the contact-forming to isolate subsequently deposited layers from the thin film. The isolation layer may be carbon or a thin layer of nickel. A connection layer for attaching an external electrical conductor is deposited on the isolation layer. The connection layer may be aluminum, chromium or a layer of copper, provided a copper layer is covered with one of silver, aluminum or a thin layer of nickel, preferably covered with aluminum.
