THE KEY PROBLEM TO BE ADDRESSED IN PHASE I OF THIS PROJECT WILL BE TO DETERMINE THE FEASIBILITY OF A NOVEL POSITION MEASURING SYSTEM FOR A FAMILY OF COMPUTER CONTROLLED MACHINE TOOLS. THE MULTIPLE LASER MEASUREMENT SYSTEM (MLMS), WHICH FORMS THE BASIS OF THIS PROPOSAL, WILL MEASURE THE (X, Y, Z) POSITION OF THE CUTTING HEAD DIRECTLY AT RATES AND ACCURACIES SUFFICIENT FOR CLOSED LOOP POSITION CONTR ...

FUTURE MILITARY AVIONICS SYSTEMS WILL REQUIRE AT LEAST AN ORDER OF MAGNITUDE IMPROVEMENT IN MEAN TIME BETWEEN CRITICAL FAILURES. TO ACHIEVE THIS GOAL INNOVATIVE FAIL-SAFE FAULT-TOLERANT ELECTRONIC SYSTEM DESIGN CONCEPTS WILL BE NEEDED. THE APPROACH PROPOSED BY DAINA WILL BE BASED ON THE USE OF EXTERNAL ENVIRONMENT DATA, BUILT-IN RELIABILITY MODEL, ADAPTIVE STATISTICAL SYSTEM STATE AND PARAMETER ES ...

A NEW CLASS OF EXTREMELY FAST SINGLE-CHIP SIGNAL PROCESSORS BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT) HAS RECENTLY BECOME AVAILABLE THROUGH AN INTENSE DEVELOPMENT EFFORT BY DARPA AND THE U.S. AIR FORCE. ONE APPLICATION OF THIS NEW TECHNOLOGY IS THE MULTIPLEXING AND PROCESSING OF IR FOCAL PLANE SIGNALS FOR STARTING AND SCANNING ARRAYS. THE PROPOSED PROGRAM SEEKS TO DEVELOP ...

THIS PROPOSAL IS FOR THE DESIGN OF A COVERT COMMUNICATIONS SYSTEM BASED ON ACOUSTIC CHARGE TRANSPORT (ACT) FILTER TECHNOLOGY. THIS SYSTEM IS COVERT IN THAT A NEARBY UNFRIENDLY RECEIVER WILL BE UNLIKELY TO DISCOVER THE PRESENCE OF THE TRANSMITTED SIGNAL, WHILE A MORE-DISTANT FRIENDLY RECEIVER WILL ONLY DETECTS THE SIGNAL, BUT ALSO MAINTAINS AN ADEQUATE SIGNAL-TO-NOISE RATIO. THE TECHNICAL APPROACH ...

THIS PROPOSAL DESCRIBES A PROGRAM FOR THE DEVELOPMENT OF A FREQUENCY CHANNELIZER AND PROCESSOR FOR ESM, ECM, COMMUNICATIONS, OR SURVEILLANCE APPLICATIONS. THIS SYSTEM IS BASED ON THE EMERGING TECHNOLOGY OF ACOUSTIC CHARGE TRANSPORT (ACT) WHICH ALLOWS THE FUNCTIONS OF FILTERING, DELAY, DETECTION, AND SWITCHING TO BE PERFORMED ON A SINGLE GALLIUM-ARSENIDE CHIP. THE PROPOSED PHASE I PROGRAM SEEKS TO ...

TWO OR MORE FREQUENCY HOP RADIOS OPERATING IN A COMMON SITE CREATE A SUBSTANTIAL INTERFERENCE PROBLEM BECAUSE CONVENTIONAL FIXED FILTERING TECHNIQUES WITHOUT FREQUENCY AGILITY CANNOT BE USED TO SUPPRESS IT. A NEW ENABLING TECHNOLOGY CALLED ACOUSTIC CHARGE TRANSPORT (ACT) HAS GIVEN RISE TO A FAMILY OF PROGRAMMABLE FILTERS THAT HOLD PROMISE FOR REDUCING THIS INTERFERENCE PROBLEM. THE PROGRAMMING TIM ...

THE COMPLETE DESIGN IS PRESENTED WITHIN THIS PROPOSAL FOR A SYSTEM WHICH WILL PROVIDE A PRECISE, ONE-STEP CONVERSION DIRECTLY FROM A PULSE TRAIN INPUT TO A DIGITIZED PULSE RATE OUTPUT. IT IS A DISTRIBUTED PROCESSOR SYSTEM EMPLOYING A MASTER CONTROL PROCESSOR AND FROM 2 TO 30 IDENTICAL PULSE MODULES. THE PULSE MODULE IS A STANDALONE UNIT WHICH PERFORMS THE PULSE PERIOD MEASUREMENT. THE MICROPROCESS ...

THE PROPOSED NIGHT VISION GOGGLES "EAGLE EYE", DEVELOPED BY NIGHT VISION CORPORATION WEIGHT UNDER 500 GRAMS, AND ARE HELMET MOUNTED CLOSE TO THE FACE, PROVIDING MAXIMUM FREEDOM OF MOVEMENT WHILE GREATLY ATTENUATION VIBRATION. THE CENTER OF GRAVITY IS A MERE 18 MM IN FRONT OF EYES, MAKING THEM EJECTION-SAFE. "EAGLE EYE" NVG'S EMPLOY A UNIQUE FOLDED OPTICAL PATH INCORPORATING A PROPRIETARY LENS SYST ...

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 ...

HIGH-PRESSURE, LARGE DIAMETER WATER NOZZLES USED FOR FIGHTING FIRES CANNOT BE OPERATED SAFELY OR EFFICIENTLY BY INDIVIDUAL FIREFIGHTERS. THIS PROPOSAL DESCRIBES AN INNOVATIVE NOZZLE DESIGN THAT IS EXPECTED TO LOWER THE NOZZLE REACTION FORCES BY 20-30% WITH AN ATTENDANT REDUCTION IN THROW RANGE OF LESS THAN 5%. A LABORATORY TEST PROGRAM TO VERIFY CONCEPT FEASIBILITY WILL BE FOLLOWED BY PROTOTYPE CO ...
