THIS PROPOSAL DETAILS A STUDY WHICH WILL EXAMINE THE USE OF A POWER-AUGMENTED EXOSKELETON AS AN AIRCRAFT STORELOADER. AN EXOSKELETON IS A JOINTED, EXTERNAL FRAME-WORK WORN BY A HUMAN OPERATOR IN WHICH ALL JOINTS ARE GIVEN A POWER-AUGMENTED ACTION. FORCE SENSORS DETECT USER MOVEMENTS AND, THROUGH MODERN FEEDBACK CONTROL TECHNIQUES, POWER THE EXOSKELETAL LIMBS. A USER'S STRENGTH CAN THUS BE MAGNIFIE ...

THIS PROPOSAL IDENTIFIES A STRATEGY, BASED ON NEW OFF-THE-SHELF TOOLS, PROTOTYPING, AND INTERACTION WITH MAINTENANCE PERSONNEL, FOR DEVELOPING INFORMATION PRESENTATION GUIDELINES WHICH SUPPORT MAINTENANCE PERSONNEL WITH VARIOUS EXPERIENCE LEVELS, THE ENVIRONMENTS IN WHICH THE MAINTENANCE IS PERFORMED, THE DIFFERENT MEDIA AVAILABLE FOR ONLINE INFORMATION DISPLAY, AND THE COST-EFFECTIVE OF IMPLEMENT ...

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 ...

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 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 ...

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 ...
