20120187687 | Hydroelectric Generators - Hydroelectric generators for harnessing potential energy from a flowing liquid source with a varying surface level. Hydroelectric generators may comprise platforms with buoyancies selected to remain suspended in the liquid source at a selected depth. In some examples, generation units may be fixed to the platform, the generation unit including turbines partially submerged in the liquid source, generators drivingly connected to the wheel, and electrical interfaces connected to the generator, the electrical interface configured to connect to an external power system. In some examples, hydroelectric generators may include one or more anchors connected to the platform. In some examples, generation units may include rotors. In some examples, hydroelectric generators may include projections extending into the liquid source and define channels between the projections. | 07-26-2012 |
20120307502 | LIGHTING SYSTEMS INCLUDING ADAPTERS ELECTRICALLY CONNECTING LIGHTING APPARATUSES - A lighting system comprising a lighting apparatus and a lighting adapter, where the lighting adapter includes a frame, a curved reflector coupled to the frame and having a reflective surface partially enclosing an interior space and defining a focal point within the interior space, a light source disposed at least partially within the interior space and substantially at the focal point of the reflective exterior surface, wherein the light source is electrically wired to allow current to flow from an outside power source into the light source, a pair of endcaps, the endcaps centering the light source substantially at the focal point, and a pair of tombstone sockets, and where the lighting adapter includes a plurality of grooved channels, wherein the grooved channels of the lighting adapter are transversely disposed on each end of a rear-wall member, | 12-06-2012 |
20130088015 | HYDROELECTRIC GENERATORS - Hydroelectric generators for harnessing potential energy from liquid flowing from upstream portions of liquid sources to downstream portions of the liquid sources below the upstream portions, the liquid source bounded on its bottom by beds that define side portions. In some examples, hydroelectric generators may include fluid-transmissive conduits defining intake portions extending into the liquid sources, the intake portions defining fluid-transmissive interiors extending below the surface of the liquid source and liquid-permissive intake openings providing an intake fluid path through which liquid from the liquid source may enter the fluid-transmissive interior from the liquid source. Additionally or alternatively, fluid-transmissive conduits may include transmissive portions extending from the intake portions to output ends of the fluid-transmissive conduit. Additionally or alternatively, hydroelectric generators may include generation units including generators, wherein transmissive portions extends at lengths operatively paired with the generators to generate sufficient quantities of head pressure to drive the generators. | 04-11-2013 |
