  "abstract": "An electrical power distribution system has fixed stations with AC power to DC power conversion circuitry at these stations. The converter(s) are switchable ON/OFF at outlet ports or sockets where the socket configuration permits. Standardized DC sockets accommodate a variety of voltage requirements typical of portable digital devices. In some embodiments feedback circuitry is provided to regulate the power to these devices in accordance with parameters programmed in the portable devices or in the sensing circuitry provided at each station.",
  "claims": [
    "1. In an electrical power distribution system for a building wherein AC power cables are provided to a plurality of stations in the building, the improvement comprising: AC to DC converter means for providing low voltage DC power at selected stations in the building; DC outlet sockets electrically coupled to said AC/DC converter means by voltage regulating means; whereby various DC voltages are available at said plurality of DC outlet sockets for powering devices having various voltage requirements.",
    "2. The improvement according to claim 1, wherein said DC outlet sockets include at least one of the group comprising USB ports and FIREWIRE ports.",
    "3. The improvement according to claim 1, wherein switching means is coupled between said AC to DC converter means and some of said DC outlet sockets for selectively energizing some of said DC outlet sockets.",
    "4. The improvement according to claim 3, wherein said some DC outlets sockets include at least one of the group comprising; USB ports and FIREWIRE ports.",
    "5. The improvement according to claim 3, wherein said switching means comprises a moveable support for said DC outlet socket, whereby inserting a charging device plug into said DC outlet socket energizes said AC to DC converter means and provides DC voltage to a device to be powered.",
    "6. The improvement according to claim 5, wherein said some DC outlets sockets include at least one of the group comprising; USB ports and FIREWIRE ports.",
    "7. The improvement according to claim 3, further including indicator means activated electrically by said switching means for indicating visually the electrical condition of said DC outlets.",
    "8. The improvement according to claim 5, further including a manually moveable closure for said DC outlet sockets, said switching means being responsive to manual movement of said moveable closure from closed to open for energizing said DC outlet socket.",
    "9. The improvement according to claim 8, further including indicator means activated electrically by said switching means for indicating visually the electrical condition of said DC outlets.",
    "10. The improvement according to claim 4, further including indicator means activated electrically by said switching means for indicating visually the electrical condition of said DC outlets."
