Abstract: Provided are devices for inducing a current in a closed loop superconducting material including a magnetic field source housed within a coil former substantially coaxial with the magnetic field source, and a base optionally in physical contact with a support tube. A closed loop superconducting material is held in a loop position by the coil former and the base such that current passing through the magnetic field source will produce a current in the superconducting material by induction. By a process of modified current sweep reversal, the rate of relaxation may be reduced in the superconducting material relative to the absence of a reversal.

Abstract: A system and method for identifying the location of gunfire from a moving object in which at least two spaced apart microphones are positioned on the moving object. The output from the microphones is decomposed into intrinsic mode functions by using empirical mode decomposition. A transient pulse is then identified in the intrinsic mode function representative of the gunfire. The location of the origin of the gunfire is then determined from the transient pulses through multilateration using time difference of arrival of the transient pulses by the microphones.

Abstract: An antenna having an elongated housing open at one end and defining an interior chamber. A telescoping mast has a carrier attached at a first end and a flexible antenna attached at its other end. The carrier with the attached mast and antenna is movable between a storage position in which the carrier, mast, and antenna are contained within the interior chamber of the housing, and a deployed position in which the mast and attached antenna protrude outwardly from the housing. A spring is positioned between the carrier and the housing which urges the carrier towards its deployed position. A catch mechanism selectively holds the carrier in its stored position and, when released, releases the spring to move the antenna to its deployed position.

Abstract: A method and apparatus for coherent beam combining in an array of laser beam collimators. The array of laser beam collimators includes an array of a plurality collimating lenses, each lens intercepting a respective one of a plurality of divergent laser beams. Each collimating lens is joined with adjacent collimating lenses such that an output aperture is formed with a common vertex of the adjacently joined collimating lenses. A concave mirror is positioned a distance from the common vertex for receiving a fraction of each of the collimated laser beams that passed through a portion of each of the collimating lenses that are adjacent to the common vertex, and then providing reflected fractional collimated laser beams. A sensor intercepts the reflected fractional collimated laser beams so as to provide a signal that is applied to synchronize the phase of each of the collimated laser beams.

Abstract: A method for mounting an optical fiber within a tube in which the optical fiber is positioned through the tube so that a portion of the fiber protrudes outwardly from the distal end of the tube. A curable material, such as an adhesive, is then applied to the optical fiber portion which, upon curing, forms a flexible solid material having the refractive index less than refractive index of cladding material of said fiber optic. The outwardly protruding portion of the fiber is then retracted back into the tube so that the flexible solid material isolates the fiber portion from the tube. In addition, different clamping assemblies are provided for attaching protective sheathing for the optic fiber to a mount for the optic fiber which permit easy disassembly and removal.
