  • Patent number: 8859882
    Abstract: A heat rejection system includes a plurality of panel subassemblies and a solid state heat pipe flex joint. Each panel subassembly includes a fin, a solid state heat pipe manifold, a first solid state heat pipe tube operatively connected to the solid state heat pipe manifold and secured to the fin, a second solid state heat pipe tube operatively connected to the solid state heat pipe manifold adjacent to the first solid state heat pipe and secured to the fin. The solid state heat pipe flex joint operably connects the solid state heat pipe manifolds of two of the plurality of panel subassemblies in a hermetically sealed configuration, and is configured to permit repositioning of the two panel subassemblies relative to each other.

  • Patent number: 8836169
    Abstract: A center-tapped solar array includes a plurality of series-connected solar cells connected between a positive terminal and a negative terminal for generating an output voltage. A center-tapped terminal connected to ground is connected to the plurality of series-connected solar cells at a midpoint between the positive and negative terminals. As a result, the positive terminal of the solar array has a positive voltage relative to ground greater than the center-tapped terminal and the negative terminal has a negative voltage relative to ground less than the center-tapped terminal.

  • Publication number: 20110012435
    Abstract: A battery for a power distribution system includes a cell assembly having a positive terminal and a negative terminal that together provide a relative battery DC voltage. A neutral tap is electrically connected to the cell assembly between the positive and negative terminals, splitting the voltage into positive and negative voltages. The positive terminal is at a positive DC voltage greater than the neutral tap. The negative voltage is at a negative DC voltage less than the neutral tap. The relative battery DC voltage is greater than each of the relative voltages between the neutral tap and each of the positive and negative DC voltages.
