MAGNETORESISTIVE RANDOM ACCESS MEMORY (MRAM) IS USED TO CREATE A VERY RELIABLE NONVOLATILE RECORDING DEVICE CONCEPT SUITABLE FOR STORING AT LEST 15 MINUTES OF AIRCRAFT FLIGHT DATA ALONG WITH ONE CHANNEL OF VOICE COMMUNICATIONS, AND TO DESIGN AND BUILD A BRASSBOARD RECORDING DEVICE TO DEMONSTRATE THE CRITICAL FEATURES OF THE DESIGN CONCEPTS. BOTH ELECTRICAL AND PACKAGE DESIGN OF THE MRAM AND CIRCUI ...

PROTECTIVE CLOTHING IS ESSENTIAL TO MAINTAINING OPERATIONS AND SAVING LIVES IN ENVIRONMENTS CONTAINING TOXIC MATERIALS, E.G., WARFARE CHEMICALS (WC). UNFORTUNATELY, TRADITIONAL APPROACHES TO PROTECTIVE CLOTHING HAVE RESULTED IN A TRADE-OFF BETWEEN QUALITY OF PROTECTION VS. PHYSICAL AND HEAT-STRESS BURDEN ON THE USER. THE LESS PERMEABLE FABRICS BLOCK WC BETTER BUT ALSO BLOCK THE EVAPORATION OF SWEA ...

THIS DISPLAY TECHNIQUE USES A SERIES OF ACCURATELY PLACED PARTIALLY REFLECTING MIRRORS (RESEMBLING CURVED LOUVERS) WITHIN THE VISOR THICKNESS IN AN AREA THE DISPLAY IS DESIREDTO BE OBSERVED. THE DISPLAY CAN BE PLACED AT ALMOST ANY POSITION AROUND THE HELMET EDGE. THE OPTICAL CHARACTERISTICS OF THE LOUVERS ALLOW THE DISPLAY TO BE DIRECTED TOWARD THE EYE. THE ABILITY TO BE ABLE TO DESIGN A LOUVER MI ...

PHASE I AIMS TO DEMONSTRATE THE FEASIBILITY OF FABRICATING PREFORMS FOR CERAMIC COMPOSITE SHAPES OF INTEREST TO FOSSIL ENERGY BY USING PROPRIETARY THREE-DIMENSIONAL BRAIDING TECHNOLOGY. HIGH PERFORMANCE CERAMIC COMPOSITES, OPERATING IN EXTREME CONDITIONS OF TEMPERATURE AND CORROSIVE ENVIRONMENT, REQUIRE PREFORM ARCHITECTURES THAT CAN PROVIDE TOUGHNESS, STRENGTH, AND A CAPACITY TO ELIMINATE FAILURE ...

THE PURPOSE OF THE PROPOSED PHASE I PROJECT IS TO DEMONSTRATE THAT A USEFUL SOFTWARE INTERFACE CAN BE CONSTRUCTED THAT IS CAPABLE OF FAITHFULLY CONVERTING NORMAL COMPUTER-AIDED DESIGN (CAD) OUTPUT FILES INTO A FORMAT THAT IS DIRECTLY READABLE BY THE GEANT HIGH ENERGY PHYSICS DETECTOR SIMULATION CODE. GEANT, ORIGINALLY DEVELOPED IN THE 1970S, HAS EMERGED AS A STANDARD TOOL FOR DETECTOR SIMULATION; ...

THE PREDICTION OF MESOSCALE DISPERSION, FOR EMERGENCY RESPONSE PURPOSES, IS CRITICALLY DEPENDENT UPON ACCURATELY FORECASTING THE 3-D WIND FIELD WITHIN THE DOMAIN OF INTEREST SEVERAL HOURS IN ADVANCE. CURRENTLY AVAILABLE EMERGENCY RESPONSE SYSTEMS, WHICH TYPICALLY USE SOME FORM OF GAUSSIAN DIFFUSION MODEL COMBINED WITH WIND FIELDS INTERPOLATED FROM SCATTERED SURFACE LAYER WIND MEASUREMENTS, ARE, UN ...

THE PROPOSED PROGRAM WILL ADDRESS THE CRITICAL NEEDS OF X-RAY/UV WAVELENGTH MIRROR TECHNOLOGY BY PROPOSING A NEW FABRICATION TECHNIQUE. CALLED ION ENHANCED MOLECULAR BEAM DEPOSITION, THIS TECHNIQUE IS CAPABLE OF FORMING HIGH REFLECTIVITY OPTICAL ELEMENTS BY VACUUM DEPOSITING ARTIFICIALLY STRUCTURED THIN FILM COATINGS. THIS UNIQUE APPROACH HAS PRECISE PROCESS CONTROL NECESSARY TO FORM STRUCTURALLY ...

AN NOVEL INVESTIGATION IS PROPOSED FOR THE POTENTIAL IMPROVEMENT OF THE ARMY'S COMBAT VEHICLE UNITY PERISCOPE. THE NEW DESIGN COULD BE BETTER DESCRIBED AS "ALL ANGLE" INSTEAD OF A WIDE ANGLE; HOWEVER, THIS PROPOSAL USES WIDE ANGLE IN THE SENSE OF EVENTUALLY BEING ABLE TO SEE 180, 270, OR 360 DEGREES WITHOUT POTENTIAL "BLIND SPOTS" OR ABERRATIONS. THE NEW DESIGN WOULD UTILIZE COHERENT FIBEROPTICS W ...

PRESENT VEHICLE DRIVE TRAIN DIAGNOSTICS USUALLY REQUIRE TEST STANDS AND OFTEN COMPONENT REMOVAL, MAKING THEM VERY INEFFICIENT. ON-BOARD VEHICLE TESTING CAN DRAMATICALLY INCREASE THE EFFICIENCY OF DIAGNOSITC DATA COLLECTION AND PROVIDE MORE REALISTIC, ON-LINE INFORMATION. THIS PROPOSAL DESCRIBES THE DEVELOPMENT OF A PORTABLE, NONCONTACT, RUGGED LASER DIODE VIBRATION SENSOR FOR ON-BOARD VEHICLE TEST ...
