Patents by Inventor Stephen George Pisklak

Stephen George Pisklak has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8217534
    Abstract: A power generator configuration having a distributed inverter. A system is described that includes a plurality of solar modules coupled together in series to form a string; a plurality of combiner boxes, wherein each combiner box couples together a plurality of strings in parallel; and a plurality of DC-DC converters, wherein each DC-DC converter increases a direct current (DC) voltage output of an associated combiner box. Also provided are distributed maximum power point tracker (MPPT) controls that adjust for changing conditions at individual sets of strings.
    Type: Grant

  • Patent number: 8003882
    Abstract: Methods and systems for photovoltaic roofing systems are provided. The system includes a back sheet including a length, L, a width, W, and a thickness, T, the back sheet including an overlap portion extending along length L having a width, WO and an active portion extending along length L having a width, WA. The system also includes a photovoltaic cell formed on a surface of the active portion, the photovoltaic cell including a photovoltaic member electrically responsive to an absorption of photons, a negative electrode coupled to a surface of the photovoltaic member, and a positive electrode coupled to the surface of the photovoltaic member, wherein the thickness T is selected such that thickness T plus a thickness of the photoelectric cell substantially match a thickness of a proximate non-photovoltaic roofing member when the photovoltaic roofing system is installed.

  • Publication number: 20100021641
    Abstract: Disclosed herein is a system for distributing a fluidic mass. The system includes, a receptacle, receptive of the fluidic mass to be distributed, an opening, fluidically connected to the receptacle, a surface in operable communication with the opening and receptive of a distribution of the fluidic mass from the receptacle such that a rate of the distribution of the fluidic mass is determined by a speed of the surface relative to the opening, and a substratum. The substratum is positioned below the surface and movable relative to the surface, and movement of the substratum relative to the surface controls a thickness of a base layer of the fluidic mass formed on the substratum.
