20090188264 | Modular in-frame pumped refrigerant distribution and heat removal system - An apparatus, method and system are provided for a modular in-frame pumped refrigerant distribution system. Specifically, a micro-channel heat exchanger is positioned in an equipment cabinet close to equipment that generates heat. More specifically, the micro-channel heat exchanger may be positioned on a) a shelf above the equipment, b) the back side of the equipment, or c) a shelf below the equipment. The micro-channel heat exchanger is operable to receive a refrigerant supplied by an external heat exchanger along a primary flow path, transfer heat from air above and/or near the equipment to a coil of the micro-channel heat exchanger, circulate the refrigerant to extract the heat, and return the refrigerant with an extracted portion of generated heat to the external heat exchanger along a secondary flow path. The external heat exchanger may remove extracted heat from a building via a building chilled water system or an outdoor condenser unit. | 07-30-2009 |
20090233156 | NANOSTRUCTURED BATTERY HAVING END OF LIFE CELLS - A cell-array battery is disclosed having end-of-life cells that can be activated at the end of a battery's life to, illustratively, neutralize the toxic chemicals inside the battery. In one embodiment, neutralization of the electrolyte in the battery is achieved through immobilization of the electrolyte at the end of the life of the battery by, for example, a vitrification process. Using electrowetting techniques, the electrolyte is made to contact a neutralizing substance between the nanostructures in one or more end-of-life cells, thus causing a reaction that results in the electrolyte becoming immobilized by, for example, a polymer substance. In a second illustrative embodiment, when the electrolyte contacts the substance between the nanostructures in one or more end-of-life cells, the chemical composition of the electrolyte is changed into a less toxic chemical compound, thus neutralizing the electrolyte. | 09-17-2009 |

20100071929 | STRUCTURED DIELECTRIC FOR COAXIAL CABLE - A geometrically-structured coaxial cable may prevent infiltration of water vapor and other contaminants by using a closed cell structure. The cable may be fabricated by wrapping bubble tape around its central conductor. Alternatively, plastic may be extruded through channels to create a plurality of layers. In either case, these layers are staggered in a zig-zag pattern to ensure that no radial spokes connect the inner and outer conductors of the coaxial cable without passing through a plurality of dielectric layers. | 03-25-2010 |
20100183906 | RESERVE CELL-ARRAY NANOSTRUCTRED BATTERY - A battery having an electrode with at least one nanostructured surface is disclosed wherein the nanostructured surface is divided into cells and is disposed in a way such that an electrolyte fluid of the battery is prevented from contacting the portion of electrode associated with each cell. When a voltage is passed over the nanostructured surface associated with a particular cell, the electrolyte fluid is caused to penetrate the nanostructured surface of that cell and to contact the electrode, thus activating the portion of the battery associated with that cell. The current/voltage generated by the battery is controlled by selectively activating only a portion of the cells. Multiple cells can be active simultaneously to produce the desired voltage. The more cells that are active, the higher the current/voltage and the lower the overall life of the battery. The life of the battery can be extended by activating fewer cells simultaneously. | 07-22-2010 |
20100221597 | REVERSIBLY-ACTIVATED NANOSTRUCTURED BATTERY - A battery having a nanostructured battery electrode is disclosed wherein it is possible to reverse the contact of the electrolyte with the battery electrode and, thus, to return a battery to a reserve state after it has been used to generate current. In order to achieve this reversibility, the nanostructures on the battery electrode comprise a plurality of closed cells and the pressure within the enclosed cells is varied. In a first embodiment, the pressure is varied by varying the temperature of a fluid within the cells by, for example, applying a voltage to electrodes disposed within said cells. In a second illustrative embodiment, once the battery has been fully discharged, the battery is recharged and then the electrolyte fluid is expelled from the cells in a way such that it is no longer in contact with the battery electrode. | 09-02-2010 |

A closed-cell feature is used in a way such that, when the pressure of at least a first fluid within one or more of the cells of said surface is decreased to or below a desired level, a droplet disposed on that surface is caused to at least partially penetrate the surface. In another illustrative embodiment, the pressure within one or more of the cells is increased to or above a desired level in a way such that the droplet of liquid is returned at least partially to its original, unpenetrated position. In yet another embodiment, a closed-cell structure feature pattern is used to prevent penetration of the nanostructured or microstructured surface, even when the pressure of the fluid disposed on the surface is relatively high. | 03-15-2012 |
