| 20120093288 | Remotely-Aligned Arcuate Detector Array for High Energy X-ray Imaging - A scanning system and methods for inspecting contents of a container. High-energy penetrating radiation collimated into a fan beam illuminates an inspected container from one side, while a plurality of detector plates are disposed on the opposite side of the container. Each detector plate has a plurality of detector modules, each of which, in turn, is disposed on a remotely activated alignment and has multiple detector elements. A controller governs the orientation of each of the plurality of detector plates based at least on the detector signal generated by its detector elements such that each detector element of each detector module of each detector plate may be aligned to within a specified fraction of the transverse dimension of the fan beam as measured at the exit slot. | 04-19-2012 |

| 20080245930 | HIGH INTENSITY LASER POWER BEAMING RECEIVER FOR SPACE AND TERRESTRIAL APPLICATIONS - Systems and methods are described that facilitate refueling a vehicle with electrical energy by targeting receiver thereon and pointing a high-intensity laser source at the receiver. Vertical multi-junction (VMJ) photocells receive the laser energy and convert the laser energy into electrical energy. The laser source can operate at a range of output power levels depending on the vehicle's energy needs. The laser source can be pulsed or continuous near-infrared laser source. A heat exchanger can be coupled to the receiver to dissipate laser energy not converted into electrical energy. If the vehicle has a propeller, the heat exchanger can be mounted to the vehicle in the propeller wash path. | 10-09-2008 |

| 20110312454 | TENSIONER WITH MICRO-ADJUSTMENT FEATURE - In one aspect, the invention is directed to a belt tensioner for tensioning a belt, comprising a pivot shaft that is fixedly mountable with respect to an engine block of an engine, a tensioner arm rotatably mounted to the pivot shaft for pivoting about a tensioner arm axis in a first direction and in an opposing second direction, a pulley rotatably mounted to the tensioner arm for rotation about a pulley axis, and a tensioner spring positioned to bias the tensioner arm in the first direction, wherein the tensioner spring has a first end and a second end, wherein the first end is engaged with the tensioner arm, and a micro adjustment mechanism that is operatively connected to control the position of the second end of the tensioner spring so as to control the tension in the tensioner spring. | 12-22-2011 |

| 20090060513 | REMOTE OPTICAL CONTROL OF ELECTRICAL CIRCUITS - An optical controlling circuit and an electrical controlled circuit such as a motor control circuit are interconnected by an electro-optic interface. A passive optical switch located in the optical circuit at a position remote from the electrical circuit is physically actuated to generate a change in optical transmission state of the optical circuit. At the electro-optic interface, the change in optical transmission state of the optical circuit is detected and triggers a change in the electrical transmission state of the electric circuit. Embodied as STOP and START pushbuttons, a pair of such passive optical switches at a position remote from the electric circuit reduces the risk that actuating motor control circuits and the like will cause arcing and, in hazardous environments, explosion. | 03-05-2009 |
