ELECTRO-OPTIC MATERIALS CONSISTING OF RANDOM DISPERSION OF NEMATIC LIQUID-CRYSTAL MICRODROPLETS EMBEDDED IN AN ISOTROPIC TRANSPARENT POLYMERIC MEDIA (OR POLYMER DISPERSED LIQUID CRYSTALS (PDLC)) WERE DEVELOPED AT ADVANCED SURFACE TECHNOLOGY, INC. (AST) FOR USE IN OPTICAL AND ELECTRO-OPTICAL DEVICES. PDLC MATERIALS CAN BE APPLIED AS A TUNABLE OPTICAL FILTER WHICH CAN RESPOND TO AN ELECTRIC FIELD AN ...

THE EXHAUST GASES LEAVING AN AIRCRAFT THAT IS FLYING AT ALTITUDES IN THE HIGH TROPOSPHERE AND LOWER STRATOSPHERE (30,000 TO 60,000 FT) ARE SUBJECT TO COLD TEMPERATURES AS THEY MIX WITH THE AMBIENT AIR. AERODYNE RESEARCH, INC. (ARI) HAS RE- CENTLY MADE SIGNIF ICANT CONTRIBUTIONS IN TACKLING PHYSICAL AND TECHNICAL PROBLEMS RELATED TO CONTRAIL F ORMATION. UNDER NASA SPONSORSHIP, ARI HAS BEEN STUDYING ...

Future military satellite fiber optic systems require a matrix optical switch for reconfigurability. But to date, no MEMS based switch has been able to withstand the harsh shock and vibration environment of space. Agiltron, Inc., an experienced manufacturer of aerospace qualified optical switches, proposes to realize a new MEMS-based fiber-optic matrix switch capable of vastly improved performance ...

NEW TECHNIQUES HAVE BEEN DEVELOPED OVER THE PAST 36 MONTHS THAT OFFER SIGINIFICANT POTENTIAL FOR ON-BOARD MONITORING OF MECHANICAL SYSTEMS TO DETECT AND CLASSIFY INCIPENT FAILURES. MANY ARE BASED ON THE WAVELET TRANSFORM, AND ITS EXTENSION TO THE WAVE PACKETS TRANSFORM. ALL PROVIDE A MEANS TO ISOLATE CHANGES IN SIGNAL STRUCTURE IN TERMS OF SCALE AS WELL AS IN TERMS OF TIME. THIS EFFORT PROPOSES TW ...

WE PROPOSE AN EFFICIENT AND COST-EFFECTIVE QUERY PROCESSING COMPONENT FOR AN INFORMATION RETRIEVAL SYSTEM BASED ON THE USE OF NETWORKED MICROCOMPUTERS AS A LOOSELY-COUPLED NETWORK DATABASE. THE QUERY PROCESSSING SYSTEM WILL WORK ON BOTH LOCAL AND WIDE AREA NETWORKS AND CAN BE USED WITH ANY METHOD OF INFORMATION RETRIEVAL. WE PROPOSE TO: 1. MODEL THE EXPECTED PERFORMANCE OF THIS SYSTEM SO THAT IT M ...

A key challenge for battlefield mission rehearsal and training systems is the estimation of enemy courses of action (COAs). Currently, adversarial COA development is a manual time-consuming process prone to errors due to limited knowledge about the adversary and its ability to adapt. Development of battlefield simulations with embedded technology that can predict its adversary’s intent and range ...

THIS PROPOSAL SEEKS TO ESTABLISH THE FEASIBILITYOF APPLYING NEWLY DEVELOPED MORPHOLOGY-BASED IMAGE SCREENING AND DETECTION ALGORITHMS TO THE MINERAL DEVELOPMENT SITE DETECTION PROBLEM IN PANCHROMATIC AND MULTISPECTRAL IMAGERY AND TO DESIGN AN OVERALL PROCEDURE FOR INTEGRATING THIS TECHNOLOGY INTO AN EFFECTIVE, PRACTICAL AND USER FRIENDLY IMAGE ANALYST TOOL. OUR UNIQUE MORPHOLOGICAL APPROACH ENABLE ...

Fully autonomous, taskable robots for use in unconstrained environments are still a dream rather than a reality because of a host of problems, including capabilities of existing sensors, effectors, and control/planning software. Indeed, concepts of operations for robot use are tending toward robots collaborating directly with humans, in relationships similar to bomb squad dogs. Fortunately, enough ...

COMPANIES THAT ARE IMPLEMENTING SIMULTANEOUS ENGINEERING OF PRODUCTS FACE SEVERAL PROBLEMS LACK OF TOOLS THAT SUPPORT COLLABORATION; LACK OF SUPPORT FOR HIGH-BANDWIDTH COMMUNICATION MEDIA TO INCREASE THE COLLABORATION BETWEEN MARKETING AND DEVELOPMENT; AND LACK OF TOOLS THAT SUPPORT INTEGRATION OF CROSS FUNCTIONAL AND CROSS DOMAIN TOOLS IN A TEAM CONTEXT. TO ADDRESS THESE PROBLEMS WE AT CRYSTALIZ ...

SYSTEM LEVEL DESIGN DECISIONS ARE KEY TO MULTI-COMPONENT SYNTHESIS: THE DETERMINATION OF WHERE TO SPLIT THE FUNCTIONALITY AMONG COMPONENTS HAS A GREAT EFFECT ON THE SIZE AND PERFORMANCE OF THE DESIGN. BY PARTITIONING A BEHAVIOR ONTO SEPARATE MODULES EARLY IN THE DESIGN PROCESS, THE PHYSICAL IMPLICATIONS CAN BE PROPAGATED TO LATER DESIGN STAGES. DASYS PROPOSES TO DEVELOP A TOOL TO AID IN THE DESIGN ...
