20090218437 | Torsional spring aided control actuator for a rolling missile - A control actuator system. The novel system includes a control surface mounted on a body and adapted to move in a first direction relative to the body, and a first mechanism for storing energy as the control surface moves in the first direction and releasing the stored energy to move the control surface in a second direction opposite the first direction. In an illustrative embodiment, the system is adapted to rotate an aerodynamic control surface of a rolling missile, and the first mechanism is a torsional spring arranged such that rotating the control surface in the first direction winds up the spring and releasing the spring causes the control surface to oscillate back and forth, alternating between the first and second directions. In a preferred embodiment, the spring has a spring constant such that the control surface oscillates at a natural frequency matching a roll rate of the missile. | 09-03-2009 |

20100129852 | Integrated Bioanalyzer - The present invention relates to an in vitro assay method and device that provides for detection and measurement of entities in a fluid sample that can be captured and concentrated in a unitized self-contained enclosed filter apparatus that is analyzed in an optical detection instrument for indications of the entity. It provides for analysis of biological material including cells, their enzymes, or other constituents thereof, that can be identified based on an indicator-generating means. The analyses provided for include detection of the presence of the entity, and changes in the entity over time, such as associated with growth and increasing metabolic activity with an expanding population of cells, or decreasing metabolic activity, for example, due to presence of inhibitory or toxic agents. | 05-27-2010 |

20090117257 | Catalysts for Fuel Cell Applications Using Electroless Deposition - In one embodiment, the present disclosure is directed to a process for electroless deposition of metal atoms on an electrode to form a core and shell structure. The process includes treating a carbon-containing support by contacting the carbon-containing support with a treatment. The carbon-containing support is impregnated with a core component metal to form at least one seed site on the carbon-containing support. A predetermined amount of shell component metal is deposited on the at least one seed site of the core component through electroless deposition by contacting the carbon-containing support with a metal salt and a reducing agent. The shell component forms at least one complete monolayer on the core component. The amount of the shell component deposited is predetermined by using the surface area of the core component. | 05-07-2009 |
