  • Laser trimming to tune the resonance frequency of a spiral resonator, the characteristics of a high temperature superconductor filter comprised of spiral resonators, or the resonance frequency of a planar coil
    Publication number: 20050256009
    Abstract: This invention provides a laser trimming method for tuning the frequency of a spiral resonator, and for improving the characteristics of a high temperature superconductor filter comprised of high temperature superconductor spiral resonators, by tuning the individual high temperature superconductor spiral resonators. This invention also provides a method for tuning the resonance frequency of a high temperature superconductor planar coil. This invention also provides a laser ablation process for creating high temperature superconductor circuit elements.

  • Surface preparation of substances for continuous convective assembly of fine particles
    Patent number: 6521541
    Abstract: A method for producing periodic nanometer-scale arrays of metal or semiconductor junctions on a clean semiconductor substrate surface is provided comprising the steps of: etching the substrate surface to make it hydrophilic, forming, under an inert atmosphere, a crystalline colloid layer on the substrate surface, depositing a metal or semiconductor material through the colloid layer onto the surface of the substrate, and removing the colloid from the substrate surface. The colloid layer is grown on the clean semiconductor surface by withdrawing the semiconductor substrate from a sol of colloid particles.

  • Wheelchair using one or more DC to DC converters to power accessories
    Patent number: 6222282
    Abstract: A personal mobility vehicle having an accessory power system includes a drive wheel, an electric motor coupled to the drive wheel, a main power source connected to the motor, and an accessory power source energized by the main power source. The accessory power source provides an accessory output at a voltage that is independent of fluctuations in the voltage supplied by the main power source.
