Abstract: A fire fighting system for fighting forest and brush fires under dry, hot and windy conditions which includes a jet engine for generating a high speed air stream, a water source for supplying water to a cooling system which lowers the water temperature to between forty and fifty degrees fahrenheit, a nozzle for injecting cold water into the air steam and a filter which provides very fine particles of cold water within the stream. The stream of cold water is directed to a forest or brush fire dropping the temperature of the fire which eventually extinguishes the fire.

Abstract: A supplemental fluid adjustable depth air sparging system which is used to remediate contaminates from groundwater within the soil. An adjustable depth air injection point injects compressed air, and an adjustable depth chemical injection point injects a chemical oxidizer or nutrient into saturated or groundwater regions of the soil's subsurface to remove contaminants including chlorinated solvents from the soil's subsurface.

Abstract: A partially shorted microstrip antenna configured to wrap around a projectile's body without interfering with the aerodynamic design of the projectile. The microstrip antenna has three identical conformal antenna elements equally spaced around the circumference of the projectile's body. The antenna has an operating frequency of 231.0 MHz±400 KHz. Each antenna element includes a plurality of vias which operate as a partial short connecting the radiating element to the ground plane and thereby increase the bandwidth of the antenna element.

Abstract: An antenna design, having two symmetrical phased array blade antenna elements which provide improved lateral target coverage with an increased effective radiated power and exhibits smooth null-free unidirectional antenna patterns. The direction of the unidirectional antenna pattern is dictated by a switching command under control of a user. Each blade antenna element is coupled to a 90-degree hybrid coupler and an RF switching device by a semi-rigid RF cable. Each blade antenna element is also connected to a sub-resonant choke balun for improved impedance matching and resultant distortion-less antenna patterns.

Abstract: A locking mechanism for securing an articulated folding wing assembly in a fully extended position by means of a tapered locking plunger urged by a coiled compression spring to contact a complementary mating surface formed on the wing assembly. The spring urged locking plunger is released from a retracted position by rotation of the wing assembly from the folded position to the extended position. A folding mechanism for rotating the wing assembly through a compound angle from the folded position to a rigid and positively locked fully extended position is provided wherein the extended wing may be rotated about its longitudinal axis to provide directional control to the vehicle.

Abstract: A self-contained fuze module, for installation on pieces of ordnance, having sensing devices and processing capability within the fuze module to determine whether conditions have been met to arm the ordnance. The fuze module is a unitary sealed module communicating with a launch vehicle via one or more communication/power buses.

Abstract: A target object motion estimation method using at least one subset of a complex SAR image. Coarse range cell alignment is performed on at least one subset of a complex SAR image. At least one subset is autofocused, thereby providing an estimated phase error function. The estimated phase error function yielded by autofocusing (or a manipulated version of the phase error function) may be analyzed to detect, characterize, and estimate target object motion.

Abstract: An apparatus and a method to initiate a detonation utilizing an impact switch. A nose assembly is mounted upon a missile or other kind of explosive device. Within the nose assembly conductive elements are separated from one another. The conductive elements are electrically connected to a fuze within the weapon. Upon an impact, the conducting elements within the assembly are forced together thereby completing a circuit in the fuze and initiating a detonation. A method of initiating a detonation utilizes an impact switch within which forcing conducting elements together initiates a detonation.
