20100124677 | DIRECT OXIDATION FUEL CELL SYSTEM WITH UNIFORM VAPOR DELIVERY OF FUEL - A fuel cell system which includes a fuel distribution structure that uniformly distributes vaporizing fuel to a fuel cell is provided. As the fuel travels in a flow field channel in the fuel distribution structure, it is substantially converted to a vapor by the heat of the fuel cell operation in such a manner that the resulting vapor pressure works to substantially uniformly distribute fuel evenly outwardly across substantially the entire active area of the anode aspect of one or more membrane electrode assemblies in the system, and whereby localized, uneven “hot spots” of fuel at the anode aspects are substantially prevented. A pair of enthalpy exchanger and heat spreader assemblies include a cathode current collector element that also has a heat spreader plate that collects and redirects heat in the fuel cell system, the assembly acting to manage the heat, temperature and condensation in the fuel cell system. | 05-20-2010 |

20100108534 | ELECTROCHEMICAL ACTUATOR - A valve system includes a gas generator coupled to a first chamber and a passage for conveying a flow of fluid therethrough. The first chamber is configured to hold a gas generated by the gas generator. The chamber includes a diaphragm deformable in response to an increase in an amount of the gas in the first chamber received by the gas generator. A deformation of the diaphragm in response to the increase in the amount of the gas in the first chamber inhibits flow of the fluid through the passage. | 05-06-2010 |
20100108536 | ELECTROCHEMICAL ACTUATOR - An electrochemical actuator system includes a membrane electrode assembly coupled to a source of electrical energy. The membrane electrode assembly includes a proton-exchange membrane disposed between a first electrode and a second electrode. A first chamber is located on a first side of the membrane electrode assembly and is configured to hold a gas generated by applying electrical energy to the first electrode of the membrane electrode assembly. The membrane electrode assembly and the first chamber are sealed to inhibit fluid communication with the surrounding ambient environment. The chamber includes a diaphragm deformable in response to a change in an amount of the gas in the first chamber. A deformation of the diaphragm in response to the change in the amount of the gas in the first chamber causes a movement of an actuating member coupled to the diaphragm. | 05-06-2010 |
20100112381 | ELECTROCHEMICAL ACTUATOR - A heat switch system includes a first surface thermally coupled to at least a portion of an associated component requiring temperature control. A second surface is spaced by a gap relative to the first surface. A gas generator is coupled to a first chamber configured to hold a gas generated by the gas generator. The first chamber includes a diaphragm configured to be deformed in response to an increase in an amount of the gas in the first chamber. A deformation of the chamber in response to the increase in the amount of the gas in the first chamber causes movement of the first surface and/or the second surface such that the first surface and the second surface move toward each other to reduce the gap and heat is transferred from the first surface to the second surface. | 05-06-2010 |
20140234740 | DIRECT OXIDATION FUEL CELL SYSTEM WITH UNIFORM VAPOR DELIVERY OF FUEL - In one embodiment, a membrane electrode assembly of a fuel cell has an anode aspect and a cathode aspect. A fuel distribution structure is disposed adjacent to the anode aspect. The fuel distribution structure has a fuel feed port configured to receive and inject liquid fuel to a flow field plate. The flow field plate has flow channels formed therein that split and spread from the fuel feed port to exit ports. The flow channels are configured to convey heat to fuel passing there through to substantially convert the liquid fuel to vaporous fuel within the flow channels. The exit ports are configured to deliver the resulting vaporous fuel to the anode aspect to substantially uniformly distribute fuel across the anode aspect. Further, an enthalpy exchanger and heat spreader assembly is in thermal contact with the fuel distribution structure and configured to provide to it heat from fuel cell operation. | 08-21-2014 |

20100168522 | SURGICAL ACCESS ASSEMBLY - A surgical access assembly configured and dimensioned for positioning within an intercostal space defined between a patient's adjacent ribs to facilitate passage of a surgical instrument into an internal work site. The surgical access assembly includes a body portion that may be either partially or wholly formed from a resilient material such that the surgical access assembly is resiliently deformable to facilitate conformity with the intercostal space in order to minimize the application of force to the patient's tissue upon insertion and removal of the access assembly and manipulation of the surgical instrument. | 07-01-2010 |
20110264091 | APPARATUS AND METHOD FOR SEALING SPECIMEN FOR RETRIEVAL - A method for modifying a tissue specimen includes providing a specimen modifying apparatus configured to modify the specimen to thereby prevent seeding from the specimen. The specimen modifying apparatus is inserted through an opening in tissue and positioned adjacent the tissue specimen to be modified. The tissue modifying apparatus is activated to modify the tissue specimen to thereby inhibit seeding from the tissue specimen. | 10-27-2011 |

20130327598 | ELEVATOR CAR MOVEMENT CONTROL IN A LANDING ZONE - An exemplary method is useful for controlling movement of an elevator car in an elevator system that includes a machine that selectively moves the elevator car and a machine brake that selectively resists movement of the elevator car. The method includes determining whether the elevator car is near a landing and determining whether a door of the elevator car is open. A desired operation includes desired movement of the elevator car while the elevator car is near the landing and the door is open. A determination is made whether the elevator car moves other than according to the desired movement. The machine brake is applied for stopping movement of the elevator car responsive to elevator car movement other than the desired movement while the elevator car is near the landing and the door is open. | 12-12-2013 |
