Historical methods of reliability assessment are less and less effective as device sizes shrink. Larger sample sizes and longer duration tests are increasingly needed. At the same time, efforts to continue scaling semiconductors to ever smaller geometries is leading to an explosion of new device structures, materials and processes. The cost of testing these innovations is becoming a major barrier ...

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 ...

A PROJECT IS PROPOSED TO DEVELOP A BIOSENSOR FOR MEASURING PATHOGENIC MICROORGANISMS IN WATER BY MEASURING CHANGES IN CONDUCTANCE ACROSS MICROPOROUS, POLYCARBONATE MEMBRANE COATE WITH SPECIFIC ANTIBODIES. THE MEMBRANES WILL BE COATED WITH HYDROPHILIC POLYMERS USING PHOTOCHEMICAL COUPLING. ANTIBODIES SPECIFIC FOR THE ANALYTE WILL THEN BE COUPLED TO THE POLYMER-COATED MEMBRANES PRIMARILY IN THE PORE ...

THIS PROJECT WILL DEMONSTRATE THE PRACTICALITY OF AN INTERACTIVE, HIERARCHICAL, DISTRIBUTED PLANNING SYSTEM FOR LOGISTICS MANAGEMENT. WE WILL DESIGN A SYSTEM THAT WILL SUPPORT PARALLEL, ASYNCHRONOUS, INTERACTIVE LOGISTICS PLANNING AT MULTIPLE LEVELS OF THE MANAGEMENT HIERARCHY AND AT MULTIPLE SITES SO THAT MANY PEOPLE COOPERATIVELY BUILD AND ADMINISTER A LOGISTICS PLAN. FOR EXAMPLE, A HIGHER-LEVEL ...

TO ENSURE RELIABLE PRODUCTION OF CARTRIDGE CASINGS, CRITICAL DIMENSIONS, SUCH AS THE PLACEMENT AND SIZE OF THE PRIMER CUP AND VENT HOLE, MUST BE ACCURATELY MAINTAINED. CURRENTLY, THERE IS NO ABILITY TO MEASURE CRITICAL DIMENSIONS OF THE PRIMER CUP DURING THE PRODUCTION OF THE 5.56MM CARTRIDGE CASING. IN THIS PROPOSAL, CYBER-OPTICS DESCRIBES A PROGRAM TO DEVELOP A PROTOTYPE INSPECTION STATION TO ME ...

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 ...

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 ...

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 ...
