Abstract: A system and a method for coupling multiple pump light beams to an active fiber. The system including an inverted conical disk, concave lens or glass wedge, an active fiber placed in a center of the inverted conical disk (or concave lens) or at a bottom facet of the glass wedge and a plurality of pump light sources. The system further includes a plurality of lenses for focusing pump light beams from pump light sources towards a side of the inverted conical disk, concave lens or glass wedge, wherein the inverted conical disk, concave lens or glass wedge, couples the pump light beams into the active fiber. A method for coupling multiple pump light beams to an active fiber. The method includes providing an inverted conical disk, concave lens or glass wedge. The method further includes providing an active fiber in approximately the center of the inverted conical disk (or concave lens) or at a bottom facet of the glass wedge.

Abstract: An exemplary system and method are disclosed for providing a combined video stream with geospatial information. Embodiments use a visualization tool to synchronize information in a virtual camera with attributes, such as video frames, from a physical camera. Once the camera position information is supplied to the visualization tool, the visualization tool retrieves geospatial data, such as terrain features, man made features, and time sensitive event data, and transforms the camera position information into a coordinate system of the virtual camera. The visualization tool uses the coordinate system of the virtual camera to generate geospatial snapshots. Embodiments use locative video software to combine the video frames from the physical camera with the geospatial snapshots from the virtual camera to generate a combined video stream, which provides a single view of multiple types of data to enhance an operator's ability to conduct surveillance and analysis missions.

Abstract: A wet cyclone particle collector is disclosed. The wet cyclone particle collector includes a cyclone unit, a liquid delivery unit and a sample collection unit. The cyclone unit draws a gas sample into a cyclone chamber and creates a circular flow of the gas sample inside the cyclone chamber so that particles in the gas sample are separated from said gas sample by centrifugation force. The liquid delivery unit delivers a collection liquid into the cyclone in a non-continuous fashion. The sample collection unit harvests the collection liquid from the cyclone unit. The non-continuous delivery of the collection liquid significantly reduces consumption of collection liquid during operation of the particle collector.

Abstract: A photovoltaic semiconductor solar cell with a backside semiconductor-oxide-nitride-oxide nonvolatile charge storage structure (referred to as a “PHONOS solar cell”) is disclosed. The PHONOS solar cell includes a semiconductor surface region, a semiconductor bulk region, and a backside structure that includes the SONO nonvolatile charge storage structure and a backside contact. The backside SONO nonvolatile charge storage structure greatly improves solar cell efficiency gains by eliminating “backside” losses, i.e., losses due to the recombination of photo-generated minority charge carriers created by the incident sunlight. The PHONOS solar cell is a highly efficient, ultra-thin, semiconductor solar cell that can be manufactured at low cost.

Abstract: A system and method for sharing information across security boundaries including a server for sharing information between networks. The method for includes receiving data structured as semantic statements, retrieving a set of rules and ontology, processing a semantic statement from data with rules and ontology, determining whether the semantic statement is consistent with rules and ontology, and determining a fact that gives rise to an inconsistency if the semantic statement is inconsistent. The method further includes removing the fact that gives rise to the inconsistency and releasing data when the semantic statement is consistent with rules and ontology.
