Abstract: A Road Departure Sensing and an Intelligent Driving System which uses near-infrared illumination to collect a continuous sequence of images from an area ahead of a moving vehicle, measure the distance to potential obstacles or obstructions, calculate the potential for collisions, detect the edges of a road or path or changes in the surface texture of a driving surface, and warn a vehicle operator in advance of the vehicle departing the drivable surface or communicate with an unmanned vehicle navigation system to sense and supply real-world navigational data. The unmanned vehicle navigation system can be integrated with existing civilian or military vehicles to provide autonomous or semi-autonomous vehicle operation.

Abstract: A safe, reliable and rapid system for the detection of nuclear materials within containers includes the use of pulsed high-intensity gamma rays that can penetrate a container and its contents and can be detected outside the container to provide a display in which high-Z material, including lead, uranium, plutonium and other nuclear substances that absorb gamma rays are detected as black regions on the display. In one embodiment, orthogonal pulsed gamma ray beams illuminate the container from two different directions to provide three-dimensional slices from which the existence and location of nuclear threat materials can be ascertained in as little as four seconds for a 40-foot container.
