  • Patent number: 8933666
    Abstract: A method of equalizing charge states of individual cells in a battery includes measuring a previous cell voltage for each cell, measuring a previous shunt current for each cell, calculating, based on the previous cell voltage and the previous shunt current, an adjusted cell voltage for each cell, determining a lowest adjusted cell voltage from among the calculated adjusted cell voltages, and calculating a new shunt current for each cell.
    Type: Grant
    Filed: July 12, 2011
    Date of Patent: January 13, 2015
    Assignee: The Johns Hopkins University
    Inventors: Paul D. Schwartz, Mark N. Martin, Lewis M. Roufberg

  • Patent number: 6930298
    Abstract: A method and structure for minimizing one or more non-uniformities in image and position sensing detectors are provided. The structure is directed to a focal plane processor for removing non-uniformities which distort the computation of a desired property of an object of interest in an image field. The focal plane processor is capable of selectively disconnecting one or more rows and/or columns from further processing in the imaging array for those rows and/or columns which contribute to the presence of at least one non-uniformity in a video image generated by the focal plane processor. In one embodiment, the disconnection means is embodied as pre-processing circuitry which includes row and column shift registers which provide control signals to area-of-interest (AOI) switches. In another embodiment, the pixels which comprise the focal plane array are constructed in a manner which facilitates their individual isolation.

  • Patent number: 6908793
    Abstract: A process for fabricating a semiconductor device having, for example, a MISFET transistor, is provided which comprises the steps of (a) providing a partially fabricated semiconductor device comprising a substrate and a first and second polysilican layer insulatively spaced from the substrate by an insulating layer, the insulating layer having an opening therein which exposes the surface of the first polysilicon layer positioned below the second polysilicon layer and (b) exposing the partially fabricated semiconductor device to a noble gas halide to substantially remove the first polysilicon layer.

  • Publication number: 20040089885
    Abstract: A metal oxide semiconductor field effect transistor (“MOSFET”) layout with small width-length ratio allows for greater flexibility in design and density in dimension than the conventional annular technique is provided. Accordingly, higher density MOSFET of this layout gives more devices on a single semiconductor wafer. An additional benefit of this layout is a reduced current density at the enclosed terminal wherein there is less localized heating and damages of materials composing the transistor.

  • Publication number: 20040032983
    Abstract: A method and structure for minimizing one or more non-uniformities in image and position sensing detectors are provided. The structure is directed to a focal plane processor for removing non-uniformities which distort the computation of a de-sired property of an object of interest in an image field. The focal plane processor is capable of selectively disconnecting one or more rows and/or columns from further processing in the imaging array for those rows and/or columns which contribute to the presence of at least one non-uniformity in a video image generated by the focal plane processor.
