PARAMETRIC X-RADIATION (PXR) IS PROPOSED AS AN INTENSE, TUNABLE, MONOCHROMATIC HARD-X-RAY SOURCE FOR THE DETECTION OF EXPLOSIVES. THIS RADIATION IS HIGHLY COLLIMATED, HAS A BANDWIDTH OF 0.1, AND AN INTENSITY EQUAL TO THAT OF SYNCHROTRON RADIATION ON A PER ELECTRON BASIS. PXR GENERATION IS ACHIEVED BY PLACING CRYSTALS INTO THE PATH OF ELECTRON BEAMS WITH ENERGY OF 6 MEV OR GREATER. THE VIRTUAL PHOT ...

POLY-X(TM) RESINS, A NEW CLASS OF RIGID-ROD THERMPLASTICS WILL BE INVESTIGATED FOR POTENTIAL USE IN AIRCRAFT CABIN INTERIORS. THE POLY-X(TM) POLYMERS ARE THE STIFFEST KNOWN THERMOPLASTICS WITH TENSILE MODULI OF 10 GPA. BECAUSE OF THEIR HIGH STIFFNESS AND STRENGTH IT IS PROPOSED THAT THEY MAY MAKE POSSIBLE LIGHTER STRUCTURES FOR AIRCRAFT INTERIORS. IT IS ALSO EXPECTED THAT THESE NEW RESINS WILL HAV ...

A VAPOR DETECTION SYSTEM ABLE TO ANALYZE ORGANIC VAPORS AT VERY LOW CONCENTRATIONS WOULD MAKE IT POSSIBLE TO SCREEN AIR TRAVEL PASSENGERS AND THEIR BAGGAGE FOR EXPLOSIVES. THE LEVEL OF SENSITIVITY REQUIRED FOR THE DETECTOR IS BETWEEN 1 AND 100 X 10-15 G OF THE MATERIAL OF CONCERN. CURRENT DETECTORS WITH THIS SENSITIVITY ARE NOT SUITABLE FOR USE AT AIRPORT GATES. THE GOAL OF THE PROPOSED PROGRAM IS ...

IN ORDER TO PLAN AN EFFECTIVE SEARCH, COAST GUARD PLANNERS NEED TO COLLECT TRUE SURFACE CURRENT AND OCEANOGRAPHIC DATA,GET THAT DATA TO THE SEARCH PLANNERS IN A TIMELY FASHION, AND PROVIDE THE CURRENT SEARCH PLAN TO THE OPERATIONAL SEARCH ELEMENTS. DERIVED FROM THE STANDARD CODE DRIFTER, THE SELF-LOCATING EXPENDABLE, AIR DEPLOYABLE COAST GUARD SURFACE DRIFTER ("SEACS") BUOY WILL PROVIDE WORLDWIDE ...

UDT SENSORS, INC. PROPOSES A NOVEL TECHNIQUE OF MONITORING AND DETECTING LOW LEVELS OF VARIOUS GASEOUS COMPONENTS OF FIRE MY MID INFRARED SPECTROSCOPY, IN THE REGION OF 3 TO 20 MICRON. THE FIRE DETECTOR CONSISTS OF A STABLE INFRARED SOURCE, AND NARROW BAND THERMOPILE DETECTORS TUNED FOR GASEOUS BY PRODUCTS OF COMBUSTION, UNIQUE TO AIRCRAFT FIRES. SUCH THERMOPILE DETECTORS ARE CAPABLE OF IDENTIFYIN ...

THE INTRODUCTION OF NON-AZIDE GENERANTS FOR AUTOMOBILE AIRBAG SYSTEMS PRESENTS NEW CHALLENGES IN THE USE OF MATERIALS FOR INTERNAL AIRBAG COMPONENTS SUCH AS PRIMARY AND SLAG FILTERS. BECAUSE NON-AZIDES ARE MUCH HOTTER (2130 DEGREES CENTIGRADE VS. 1090 DEGREES CENTIGRADE) AND CONTAIN MORE METALLIC OXIDES THAN AZIDES, CURRENT MATERIALS OF CONSTRUCTION ARE NOT SUITABLE FOR USE WITH THESE GENERANTS. U ...

This proposal seeks to demonstrate the feasibility of using impulse radar techniques to detect and identify explosive detonators. It relies on the fact that a radar impulse will excite natural electromagnetic resonances which characterize the size, shape, and material composition of an object. These resonances are present in the scattered transient return from the object and can be extracted by ...
