20110057121	SINGLE NANOPARTICLE TRACKING SPECTROSCOPIC MICROSCOPE - A system that can maintain and track the position of a single nanoparticle in three dimensions for a prolonged period has been disclosed. The system allows for continuously imaging the particle to observe any interactions it may have. The system also enables the acquisition of real-time sequential spectroscopic information from the particle. The apparatus holds great promise in performing single molecule spectroscopy and imaging on a non-stationary target.	03-10-2011

20080308157	METHODS AND APPARATUS TO DETERMINE A POSITION OF A VALVE - Methods and apparatus to indicate a position of a valve are described. An example apparatus includes a first pressure sensor to detect an inlet pressure of a valve, a second pressure sensor to detect an outlet pressure of the valve, and a controller operatively coupled to the first pressure sensor and the second pressure sensor to determine a position of the valve corresponding to one of a plurality of predetermined operational states of the valve.	12-18-2008
20080308161	FLOW CONTROLLED ACTUATOR APPARATUS FOR USE WITH SELF-CLOSING STOP VALVES - An apparatus for operating a device such as a self-closing internal valve is disclosed. The apparatus includes a housing assembly having an internal chamber, a fluid inlet in fluid communication with the internal chamber, and an actuator stem extending from the housing assembly. The actuator stem is moveable in response to the addition or removal of a fluid into or out of the internal chamber. To control the flow rate of a fluid into and out of the internal chamber, the apparatus includes a fluid control valve in fluid communication with the fluid inlet of the housing assembly, wherein the fluid control valve is adapted to restrict the rate of fluid flow into the internal chamber of the housing assembly.	12-18-2008
