Abstract: A method and apparatus for protecting the troops when they exit an armored vehicle is provided by utilizing the universal tail light assembly and providing the assembly with wide field-of-view cameras and other sensors, with screens or displays located within the vehicle to provide situational awareness of the rear of the vehicle, thus to alert troops and their commanders as to external threats prior to troop deployment. In one embodiment, two wide-angle infrared cameras are retrofitted to existing universal tail light assemblies to either side of the vehicle, with the cameras having overlapping fields of view to permit generation of a panoramic view. Moreover, additional sensors such as ultrasonic sensors, LIDARs and laser range finders can be located in the universal tail light assembly, with the subject system not requiring breach of the already-existing armor for the vehicle.

Abstract: A wing deploy initiator for deploying guidance wings of a rocket or missile, such as the APKWS, provides enhanced wing deploy performance with reduced complexity, cost, and likelihood of failure. The invention includes a cam which is driven between the stowed guidance wings by at least one compression spring, thereby forcing the guidance wings outward through slots in the fuselage of the rocket or missile. Oblique flat sides of the cam can push against beveled edges on the wings. The cam can be attached to spring mandrels, and the cam and mandrels can pass through a retaining plate as the springs decompress. Embodiments can exert sufficient push force to enable the wings to break through frangible slot covers. An embodiment applicable to the APKWS includes only 13 parts, and can exert up to 10 lb push force on each wing after 0.3 inches of wing travel.

Abstract: An entry slit panel for a push-broom hyperspectral camera is formed at least partly from a silicon wafer on which at least one companion sensor is fabricated, whereby the companion sensor is co-planar with the slit and detects light imaged on the panel but not on the slit. In embodiments, the companion sensor is a panchromatic sensor or a sensor that detects light outside the wavelength range of the camera. At least a region of the wafer is back-thinned to a thickness appropriate for a diffraction slit. The slit can be etched or laser cut through the thinned region, or formed between the wafer and another wafer or a conventional blade. The wafer can be back-coated or metalized to ensure its opacity across the camera's wavelength range. The companion sensor can be located relative to the slit to detect scene features immediately before or after the hyperspectral camera.

Abstract: A method and apparatus is devised for detecting command wires utilized to detonate an improvised explosive device or other objects of interest in which frequency-scanned RF in the HF region of the electromagnetic spectrum is projected out across a given area and returns are detected and converted into image data in which phase, amplitude, range and frequency associated with the incoming data is correlated with frequency-dependent range templates to determine the existence of, the range of and the direction of command wires or other objects of interest.

Abstract: Methods, systems and other embodiments associated with pre-processing a signal for spectral analysis are presented. A system for pre-processing a digital input signal includes a digital down converter (DDC), an interpolator, and a series of down samplers. The DDC modulates the digital input signal to create a down converted signal. The interpolator re-samples the down converted signal to produce a re-sampled signal. The series of down samplers produces down sampled signals. The multiplexer selects one of the digital input signal, the down converted signal, and the down sampled signals and routes the selected signal to an output line.

Abstract: A real time streaming geolocation method includes recording data and linking it to specific coordinates. The data is selectively stored to a database using a specialized data filtering method, and a streaming video can be created from the stored data. The streaming video can be created in real time, creating a current video simulation of a specific environment. The method also allows for interactive addition, modification and deletion of data, such as points of interest, in the video stream.

Abstract: A software-defined tactical radio solution meets the original JTRS SWaP goals by providing four complete software-defined 125 W (peak) radio channels in four modules that replace the four UT modules of the current GMR design, while retaining the GVA and NIU of the GMR.

Abstract: An oxygen delivery system is disclosed. The basis of the oxygen deliver system is a carbide-derived carbon (CDC). The CDC can be tuned to carry O2 directly (CDC OC), or hemoglobin can be adsorbed to provide a hemoglobin-based oxygen carrier (CDC HBOC). The delivery system allows the use of a variety of hemoglobins which differ in their oxygen dissociation profiles, including variant and mutant hemoglobins from other species. The delivery system is biocompatible and stable, and is able to irreversibly bind and hold large amounts of functional hemoglobin variants. The CDC HBOC and CDC OC provide a safe and effective blood substitute for combat casualty care, as well as being useful for oxygen delivery in other contexts.

Abstract: The invention allows a shearography system to successfully sense ground/surface vibrations while moving at aircraft speeds and altitudes. This is done by effectively making stationary the apparent location of a coherent laser beam illuminating an area on the ground/surface, and also effectively making stationary the apparent location of the aperture of an optical receiver which acquires pairs of sequential images captured and used for shearography. A different laser is used for capturing each of the two images, and the distance between the two lasers is adjusted based on a number of operational parameters. The adjustment of the distance causes the apparent locations of the transmitter and a receiver sub-aperture to remain the same and permits the moving shearography to work.
