  • Patent number: 9720021
    Abstract: A method and apparatus use a programmable logic circuit to receive data representing environmental conditions such as irradiance, temperature, wind, snow, elevation, and the like, in a given location, to provide an input signal to a simulated variable power source which produces an output that approximates the output of a variable power source such as a photovoltaic panel that is subject to such environmental conditions. Power from the simulated variable power source is separately directed to each of a number of power converters and the efficiency of each power converter is tested to determine the optimum power converter for use with the variable power source in the given location.
    Type: Grant

  • Patent number: 6755551
    Abstract: A thin profile task light includes a housing having a longitudinally extending and downwardly opening window, an elongated lighting element located within the housing and including electrical connectors located at opposite ends thereof, and a plurality of electrical power sockets shaped to receive the opposite ends of the lighting element therein. The task light also includes a reflector located between the lighting element and the housing, a lens covering the window of the housing, and a power supply assembly that includes an electrical switch controlling the supply of electrical power to the lighting element, a ballast regulating the supply of electrical power to the lighting element, and a circuit board, wherein the electrical switch in the ballast mounted on the circuit board. The task light has an overall thickness of within the range of from about 0.5 inches to about 1.0 inches.

  • Patent number: 6491268
    Abstract: A platform assembly for supporting a portable computer. The platform assembly includes a support member having an outer perimeter and a plurality of engagement features spaced inwardly of the perimeter. The support member defines a support surface configured to provide weight bearing support to a portable computer. The platform assembly also includes a plurality of securing devices, each of the securing devices having fastening members releasably securably engagable with a selected one of the engagement features. Each of the securing devices has a clamping surface adapted to engage a portable computer, and the clamping surface is positionable to bear against a portable computer with a clamping force directed generally towards the support surface.
