20090291848 | Method for forming gold-containing catalyst with porous structure - The invention relates to a gold-containing catalyst with porous structure that is obtainable through a process that comprises the following steps: melting together of gold and at least one less noble metal that is selected from the group consisting of silver, copper, rhodium, palladium, and platinum, and at least partial removal by dissolving the at least one less noble metal out of the starting alloy thus obtained. The catalyst has high activity and great long-term stability, despite the fact that it does not contain a support material or a compound that serves as a support material. The catalyst can be used to accelerate and/or to influence the product selectivity of oxidation and reduction reactions. The catalyst is suitable, for example, for the oxidization of carbon monoxide to carbon dioxide, which makes it usable, among other things, in a fuel cell, in particular a polymer electrolyte membrane fuel cell (PEM), for protection of the anode catalyst against blocking by carbon monoxide. | 11-26-2009 |

20120237853 | NANODEVICES FOR GENERATING POWER FROM MOLECULES AND BATTERYLESS SENSING - A nanoconverter or nanosensor is disclosed capable of directly generating electricity through physisorption interactions with molecules that are dipole containing organic species in a molecule interaction zone. High surface-to-volume ratio semiconductor nanowires or nanotubes (such as ZnO, silicon, carbon, etc.) are grown either aligned or randomly-aligned on a substrate. Epoxy or other nonconductive polymers are used to seal portions of the nanowires or nanotubes to create molecule noninteraction zones. By correlating certain molecule species to voltages generated, a nanosensor may quickly identify which species is detected. Nanoconverters in a series parallel arrangement may be constructed in planar, stacked, or rolled arrays to supply power to nano- and micro-devices without use of external batteries. In some cases breath, from human or other life forms, contain sufficient molecules to power a nanoconverter. A membrane permeable to certain molecules around the molecule interaction zone increases specific molecule nanosensor selectivity response. | 09-20-2012 |

20090126806 | ADJUSTABLE VACUUM RELIEF SAFETY VALVE SYSTEM FOR SWIMMING POOLS AND SPAS - An adjustable vacuum relief safety valve system includes a housing having first and second shells cooperatively defining an inner chamber in fluid communication with a pump of a pool circulation system. A sealing element within the housing is biased against an air inlet aperture of the housing by a spring so as to seal the inner chamber of the housing from the ambient air. To accommodate for different pumps, the first and second shells of the housing are connected to one another such that the compression of the spring can be altered to adjust for the pump's characteristics. During elevated negative pressure operating conditions, the sealing element is pushed into the inner chamber, permitting ambient air to flow into the inner chamber and the pump, causing the pump to rapidly lose its prime. An electronic circuit may be actuated, via a switch, for shutting off power to the pump. | 05-21-2009 |

20120095676 | ON DEMAND TTS VOCABULARY FOR A TELEMATICS SYSTEM - A driving directions system loads into memory a limited subset of prerecorded, spoken utterances of geographic names from a mass media storage. The subset of spoken utterances may be limited, for example, to the geographic names within a predetermined radius (e.g., a few miles) of the driver's present location. The present location of the driver may be manually entered into the driving directions system by the driver, or automatically determined using a global positioning system (“GPS”) receiver. As the vehicle moves from its present location, the driving directions system loads into memory new names from the mass media storage and overwrites, if necessary, those which are now geographically out of range. Based on the current location of the driving, the driving directions system can audibly output geographic names from the run-time memory. | 04-19-2012 |
