Abstract: One aspect of the invention relates to a laser ranging system. In this version of the invention, a guided missile is provided with laser that directs laser radiation in the general direction of a target that is subsequently reflected from the target back to the missile. A receiving lens is mounted on the missile that receives the reflected laser radiation. A ferrule containing optical fibers divided into a plurality of pixels that receive the reflected laser radiation from the receiving lens, wherein each pixel in the plurality of pixels is provided a different pointing angle by arranging the fibers within the pixel such that the centroid of the field of view of the fibers is different from the centroids of the field of views of the other fibers in the other pixels.

Abstract: Methods for navigating a remote controlled vehicle, methods for maintaining a formation of remote controlled vehicles, and remote controlled vehicles using those methods. A vehicle is navigated using the Global Positioning System (GPS). Upon dropout of the GPS, the vehicle is navigated using a laser tracking system and one or both of: (i) a compass and (ii) wheel encoders. The navigation system may be used, in one embodiment, to maintain an echelon formation of remote controlled mine detection vehicles.

Abstract: Systems, methods, and apparatuses for marking a substrate. In a representative embodiment, the invention involves a marking system including a marker container, a marker cutter, and a marker driver. The marker container is configured to contain marker material having flexible shaft material. The marker cutter is coupled to the marker container, and the marker driver is coupled to the marker cutter.

Abstract: An apparatus for collecting and detecting chemicals contained in a fluid includes a sorbent element, at least one chemical sensor, a first pump for pumping fluid through the sorbent element and a second pump for pumping fluid to the chemical sensor. The sorbent element contains a sorbent material and a heating element. The first pump pumps fluid into the sorbent element thereby collecting the chemicals on the sorbent material. The heating element provides heat to the sorbent element to desorb the chemicals from the sorbent material. The chemicals desorbed from the sorbent material are then pumped out of the sorbent element and to the chemical sensor. The sorbent material may have a cavity therein with the heating element located in that cavity. Alternatively, the heating element may be interposed between the enclosure and the sorbent material.

Abstract: The present invention provides a modified coupling system that can be used with camouflage systems and is particularly useful with ULCANS and LCSS camouflage systems. The present invention provides compatibility between the two dissimilar systems simultaneously while maintaining quick disconnect capabilities with either system. Further, the present invention provides a method for modifying existing ULCANS system camouflage units to meet the present need.

Abstract: The present invention provides an attachment system that can be used to interface between dissimilar camouflage systems and is particularly useful with ULCANS and LCSS camouflage systems. The present invention provides such compatibility while simultaneously maintaining quick disconnect capabilities with either system.

Abstract: Pyrotechnic compositions having combustion reaction products that include a high percentage of carbon dioxide at high temperatures. These pyrotechnic compositions include a fuel component having combustion product with a relatively high percentage of carbon to hydrogen content, such as an aromatic polycarboxylic anhydride fuel component. These pyrotechnic compositions may be employed to emit infrared radiation from a decoy flare or other device. The compositions may also be employed as a gas generating propellant for a projectile, such as a flare or rocket, or for other applications such as an automobile airbag. These pyrotechnic compositions emit infrared emissions with minimized short wavelength components, and produce substantially non-toxic combustion gases having relatively small amounts of water vapor.

Abstract: The present invention relates to a system for sweeping a laser beam in a preset pattern, while, at the same time, directing the pattern to any area in a predetermined scanning area. The invention is particularly useful in LADAR applications. In one version of the invention, a series of optical prisms are arranged in concentric tubes so that the prisms have a common optical path. The tubes and, hence, the prisms, may be independently rotated by precision electric motors coupled to gear rings on the tubes.
