Abstract:
Nuclear quadrupole resonance substance detection at a distance is provided by crossed or overlapping high frequency beams in which the frequency of one of the beams is offset with respect to the frequency of the other beam by an amount equal to the resonant frequency of the non-linear material to be detected. The presence of energy at the offset frequency within the overlapping beams pumps any non-linear material within the overlapping beams to cause stimulated emission which is detected, in one embodiment, utilizing a network analyzer, along with correlation of the detected stimulated emission signature with a library of signatures for predetermined substances.
Abstract:
A system for enabling interoperability among various kinds of communications equipment and information transmission formats on the battlefield or during tactical missions. The system includes a multi-message translator (MMT) for translating a source text message having a first set of word fields defined according to a source message format, into a sink message having a second set of word fields defined according to a sink message format. The system also includes a voice bridging gateway (VBG) for bridging multiple voice communication networks having associated transmission protocols that are incompatible with one another. Dismounted soldiers obtain location based services including geo-referenced maps, and tactical communications including voice and text messaging, using smart phones or other lightweight COTS client devices that link through a personal networking node (PNN) server to one or both of the MMT and the VBG.
Abstract:
A laser-based infrared countermeasure (IRCM) system is disclosed. The IRCM system includes a set of receive optics, a dichroic filter, first and second detectors, a lens module and a laser. Receive optics are configured to receive optical information. The lens module reflects the optical information from the receive optics to the dichroic filter. The dichroic filter selectively splits the optical information to the first and second detectors. The first and second detectors, each of which is formed by a single-pixel detector, detects a potential missile threat from the optical information. Based on information collected by the first and second detectors, the laser sends laser beams to neutralize any missile threat.
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:
A system and method for guiding a projectile is presented. A nozzle system includes a boom assembly body that can be attached to a rear end of a projectile. A gas tank in the boom assembly contains pressurized gas. Fins are attached to the boom assembly body to guide the projectile. A valve lets a pulse of gas out of the gas tank. A nozzle expels the pulse of gas to control an angle of attack and lift of the projectile to guide the projectile to a target.
Abstract:
Outside air enters a ram air scoop on an aircraft frame, and is ducted to a ram air control valve. The air control valve oiitputs a desired air mass flow to a cyclone air-water separator which removes moisture and produces a dry air flow. A heater assembly heats the dry air to a desired temperature and directs the heated air into an equipment bay enclosure on the aircraft. The relative humidity of the heated air is sensed by an air moisture sensor which produces a corresponding signal. Other sensors disposed hear a payload in the bay enclosure produce corresponding air. temperature and air pressure signals. All the sensor signals are input to a processor or controller configured to activate the air control valve and the heater assembly according to set points for temperature and humidity that are specified for the payload in the bay enclosure.
Abstract:
Stimulated emissions due to nuclear quadropole resonance are detected utilizing a terminated balanced transmission line and a directional coupler for the detection of explosives, contraband, narcotics and the like that exist between the transmission lines, with either a stepped frequency generator utilized to scan between 100 KHz and 10 MHz, or wherein parallel fixed frequency sources are coupled to the transmission line, thereby to permit correlation with expected lines, with the frequency sources being low power so as to not create a safety hazard and so as not to interfere with radiation sensitive devices such as film or electronic circuits that arc in the vicinity of the balanced transmission line.

Abstract:
Multiple input and/or gain stage Gilbert cell mixer designs are disclosed. The designs allow one input to be turned on at a time, and are suitable, for example, for use in receiver and transmitter applications. In addition, the designs allow for the inputs of the multi-input Gilbert cell mixer to be connected together, thereby allowing for switching of gain stales within the Gilbert cell mixer. T he mixer design may include, for example, a Gilbert cell mixer stage, and a plurality of input/gain stages. Each input/gain stage has its output connected to the input of the mixer stage, and is configured for receiving an input signal and applying a gain factor to that input signal to provide a signa! for mixing with the LO. Each input/gain stage is configured with stage select circuitr) for enabling or disabling that stage, so that only one input/gain stage is active at a time.
