  • Publication number: 20060250117
    Abstract: An apparatus for determining the necessary capacitance required to correct power factor in an electrical power system comprises a plurality of capacitors having predetermined capacitances connected in series with a plurality of switching devices, said capacitances and switching devices connected between the line voltages of said power system to correct power factor. A means for determining power factor in said power system may include a power factor meter or a plurality of current transmitters and voltage probes used to provide data to a microcontroller to calculate power factor.

  • Publication number: 20060013332
    Abstract: The invention is a method of sending information through a bandwidth-constrained information channel at a rate faster than the current limit of the state of the art. It accomplishes this objective by sending overlapping signals which are separated using superresolution methods such as deconvolution to distinguish between symbols which are overlapping. This method is capable of sending information through a bandwidth-constrained information channel substantially faster than the Shannon-Nyquist limit, which is the limit of the current state of the art. The method is composed of convolving the input data with a kernel; sending the result of the convolution as a signal through a communication system; deconvolving said signal with respect to the kernel; and outputting the results of said deconvolution through a means of information output.

  • Patent number: 6550840
    Abstract: A tailgate lift assembly is described herein wherein the assembly is comprised of a housing which has retained therein a spring, the spring being connected to the tailgate by means of a cable. The cable extends from the spring through at least one roller for correct positioning thereof. The cable is biased due to the spring the tension of which is adjustable through the use of a tensioning mechanism such as a turnbuckle. The lift assembly may be integrated with the top of a trailer side rail or may be affixed thereto.
