HIGHLY RELIABLE COMPUTERS ARE NEEDED TO SUPPORT EXECUTION OF SAFETY CRITICAL SOFTWARE. MODERN VLSI TECHNOLOGY, COUPLED WITH ADVANCED FAULT TOLERANCE TECHNIQUES, OFFERS THE POTENTIAL OF A COMPUTER WITH A PREDICTED RELIABILITY OF .9999 OVER A 5 YEAR OPERATING CYCLE WITHOUT REPAIR. USING VOTING TECHNIQUES TO DETECT AND MASK THE EFFECTS OF BOTH...AND TRANSIENT FAILURES, IT APPEARS PRACTICAL TO REDUCE ...

AIRCRAFT FUEL TANKS CAN BE PROTECTED FROM FIRE AND EXPLOSION BY FILLING THE VAPOR SPACE ABOVE THE LIQUID FUEL WITH AN INERT GAS SUCH AS NITROGEN. A LOW-MAINTENANCE, MEMBRANE-BASED ON-BOARD INERT GAS GENERATION SYSTEMS (OBIGGS) IS A PROMISING ALTERNATIVE TO THE CURRENTLY USED HIGH-MAINTENANCE LIQUID NITROGEN SYSTEM. HOWEVER, RECENTLY DEVELOPED MEMBRANE-BASED OBIGGS ARE INEFFICIENT IN THEIR REMOVAL ...

THERE IS AN IMPLICIT NEED FOR THE ABILITY TO PROBE INTERNAL NODES IN GAAS MMIC'S TO FACILITATE DEVELOPMENT OF THESE STRATEGICALLY CRITICAL COMPONENTS. SYSTEMS USING THE ELECTRO-OPTIC EFFECT HAVE DEMONSTRATED OUTSTANDING PERFORMANCE IN THIS APPLICATION, BUT THESE SYSTEMS ARE EX-PENSIVE AND DIFFICULT TO MAINTAIN AND USE. THE PROPOSED WORK WILL LEAD TO A SYSTEM BASED ON A CW LASER AND EXISTING AND HI ...

MAKING ACCURATE AUTOMATED ON-WAFER MEASUREMENTS OF MILLIMETER-WAVE SEMICONDUCTOR DEVICES AND CIRCUIT ELEMENTS IS A FUNDAMENTAL REQUIREMENT FOR THE ADVANCEMENT OF A MILLIMETER-WAVE TECHNOLOGY. MILLIMETER-WAVE WAFER PROBE DEVELOPMENT IS REQUIRED. PRESENTLY ON-WAFER PROBING IS AVAILABLE ONLY TO 26.5 GHZ. HOWEVER, SIGNIFICANT INNOVATIONS ARE REQUIRED TO EXTEND THIS CAPABILITY OF HIGHER FREQUENCIES. TH ...

A FEASIBILITY STUDY IS PROPOSED TO DEMONSTRATE AN ANALYSIS TECHNIQUE FOR PREDICTING THE SHOCK RESPONSE OF SHIPBOARD AIRCRAFT SUPPORT EQUIPMENT. THE PREDICTED RESPONSE OF INDIVIDUAL COMPONENTS, SUCH AS CRT'S, TAPE DRIVES, AND PC BOARDS, WOULD BE AUTOMATICALLY COMPARED TO EITHER THE COMPONENTS SPECIFICATIONS OR TEST DATA AND THE USER WOULD BE NOTIFIED OF THOSE COMPONENTS WITH RESPONSE LEVELS EXCEEDI ...

THE PROPOSED FEASIBILITY STUDY IS AN ANALYSIS OF TRACKS OF TRACKED VEHICLES TO EVALUATE ALTERNATIVE MEANS TO DAMPEN STANDING WAVES IN THE TRACKS WHICH OCCUR WHEN THE TRACKED VEHICLES OPERATE AT HIGH SPEEDS. THE STANDING WAVES ABSORB POWER AND REDUCE DRIVETRAIN EFFICIENCY. A RUGGED, INEXPENSIVE MEANS OF DAMPING THE STANDING WAVES IS DESIRED.

RA ASSOCIATES PROPOSES TO INVESTIGATE SOLUTIONS TO THE PROBLEM OF OBSOLETE INTEGRATED CIRCUITS. THIS WILL INCLUDE A SURVEY AND COMPILATION OF THE WORK UNDERWAY BY OTHERS, PLUS AN INDEPTH ANALYSIS OF SEVERAL CANDIDATE SOLUTIONS. SPECIFIC CANDIDATES INCLUDE 54ALS, 54HCT, 54ACT LOGIC FAMILITES. A SOLUTION IS PROPOSED FOR THOSE CASES WHERE THE PINOUT NEEDED IS NOT AVAILABLE. COMPUTER ANALYSIS OF EFFEC ...

A LIGHT SOURCE WILL BE DEVELOPED USING OPTICAL FEEDBACK, AND WILL BE INCORPORATED INTO A LIGHT BEAM TRANSMISSOMETER TO DEVELOP A PROTOTYPE FOR EVENTUAL PRODUCTION OF A HIGH ACCURACY, WAVELENGTH SELECTABLE BEAM TRANSMISSOMETER. THE ACCURACY IN MEASUREMENT OF PARTICLE VOLUME CONCENTRATION WITH THE EXISTING RED LIGHT (660 NM WAVELENGTH). 25 CM TRANSMISSOMETER IS APPROXIMATELY THIRTY PARTS PER BILLION ...
