THE INCREASINGLY WIDESPREAD APPLICATION OF MIL-STD-1553B TO MILITARY AND, POTNTIALLY COMMERCIAL AIRCRAFT HAS CREATED A NEED FOR DIGITAL OUTPUT FLOW ANGLE TRANSMITTERS. THE CURRENT MEANS OF GENERATING A DIGITAL OUTPUT FROM EXISITING TRANSDUCERS HAS AN UNFLAVORABLE IMPACT ON SIZE, WEIGHT, POWER, COST AND RELIABILITY. DIGITIAL ENCODING TECHNIQUES ARE BELIEVED TO HAVE BENEFICIAL APPLICATION TO EXISTIN ...

THE POSIDENT CONCEPT USES FINGER PRINT IDENTIFICATION SYSTEM TO COMPARE THE SUBJECTS LIVE FINGER PRINT WITH A STORED FINGER PRINT. THE STORAGE MEDIUM CAN BE ONE OF SEVERAL TYPES. A PHOTOGRAPHIC IMAGEIIS ONE METHOD OF STORAGE. DIGITAL DATA IN PROM IS A SECOND METHOD. THE ID CARD IS PLACED FON THE ELECTRO-OPTICAL CORRELATION DEVICE. A VIDEO CAMERA (VIDICON OR SOLID STATE CCD CAMERA) IS USED TO SCAN ...

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 ...

THE ANALYSIS OF AEROBALLISTIC RANGE DATA IS A TEDIOUS AND TECHNICALLY CHALLENGING TASK. THE SOPHISTICATED ANALYSIS PROCEDURES AND REQUIRED SOFTWARE (COMPUTER PROGRAMS) HAVE BEEN REFINED EXTENSIVELY DURING THE PAST FIFTEEN TO TWENTY YEARS WITH THE ADDITION OF THE SIX-DEGREE-OF-FREEDOM CODES EMPLOYING THE MAXIMUM LIKELIHOOD METHOD. THE REQUIRED PROFICIENCY TAKES BETWEEN THREE AND FIVE YEARS UNDER TH ...

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 ...

MAINTAINING COMMAND-AND-CONTROL COMMUNICATIONS CONNECTIVITY CONTINUOUSLY THROUGH PRE-, TRANS-, AND POST-ATTACK PERIODS IS ESSENTIAL. COMMUNICATION LINKS FOR THIS APPLICATION SHOULD BE NONDENIABLE (BY NUCLEAR DETONATION) AND NONINTERRUPTABLE, AND SHOULD ALSO ALLOW COMMUNICATIONS WHILE IN MOTION AND HIGH DATA RATES. HOWEVER, CONVENTIONAL COMMUNICATION TECHNIQUES ARE ILL SUITED FOR USE IN THIS APPLIC ...

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 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 ...
