CURRENT FRAME BUFFER TECHNOLOGY IS NOT OPTIMIZED FOR USE WITH GENERAL PURPOSE PROCESSORS. THIS PROPOSAL IS FOR A PROGRAM TO DEVELOP A BREADBOARD FRAME BUFFER WHICH IS EFFICIENTLY ACCESSED BY SUCH PROCESSORS. THE FRAME BUFFER IS BASED ON THE VME BUS AND IS SCALABLE TO LARGE AMOUNTS OF IMAGE MEMORY AND VERY FAST IMAGE ACQUISITION RATES. ALL IMAGE DATA IS RANDOMLY ACCESSIBLE AT HIGH SPEED. ANTICIPATE ...

FOUR BEARINGLESS, SHAFT MOUNTED GENERATORS WITH OUTPUTS OF 10, 100, 500 AND 1000 WATTS OF 12-15 V DC WILL BE DESIGNED AND COMPUTER MODELED TO BE DRIVEN BY MODEL AIRPLANE SIZE RECIPROCATING ENGINES. DESIGN COMBINATIONS OF IRONLESS DISK AND IRON LAMINATION CYLINDRICAL GENERATORS USING RARE EARTH AND CERAMIC PERMANENT MAGNETS WILL BE MODELED FOR RELIABILITY WITH THE LOWEST WEIGHT AT THE HIGHEST EFFIC ...

MCNC PROPOSES A FEASIBILITY STUDY AND EVALUATION OF THREE PROMISING APPROACHES TO THE FABRICATION OF SURFACE TEST STRUCTURES ON SILICON. SURFACE FEATURES ON THE FIRST STRUCTURE WILL BE PRODUCED BY CONTROLLABLY ETCHING THERMALLYGROWN OXIDES. FEATURES ON THE SECOND WILL BE MADE BY ETCHING PIEZOELECTRIC THIN FILMS. USING THE PIEZOELECTRIC FILM AS PART OF A CAPACITOR, STEP-HEIGHT CAN BE VARIED AND PRO ...

A TECHNIQUE FOR OBTAINING TRUSTWORTHY COMPILATION BASED ON A COMPILATION CHECKER (SIMILAR TO A PROOF CHECKER) IS PROPOSED. THE TRANSFORMATIONS USED IN A COMPILER WILL BE FORMALLY SPECIFIED AND VERIFIED USING INTERPRETER EQUIVALENCE METHODS. THE COMPILER WILL BE INSTRUMENTED TO PRODUCE A TRACE OF THE TRANSFORMATIONS APPLIED IN THE COMPILATION OF A GIVEN PROGRAM. THE COMPILATION CHECKER WILL VALIDAT ...

LOW OBSERVABLE (LO) OPERATIONS ARE THWARTED WHEN CONTRAILS ARE FORMED. IT IS ESSENTIAL THAT MEANS BE SOUGHT TO AUTOMATICALLY DETECT AND ONCE DETECTED, ELIMINATE THIS VISUAL SIGNATURE SO THAT THE OPERATIONAL ADVANTAGE OF REDUCED RADAR CROSS SECTION AND INFRA-RED SIGNATURES CAN BE FULLY EXPLOITED FOR OBTAINING COMBAT ADVANTAGE. A PASSIVE, EXHAUST SYSTEM DESIGN IS PROPOSED WHICH PROVIDES EXTREMELY HI ...

RESONANT ULTRASOUND INSPECTION CAN RAPIDLY FIND CRACKS FLAWS AND TOLERANCE ERRORS IN SOLID STRUCTURES. IN METALLIC BEARINGS, WE HAVE MEASURED SPHERICITY TO 50PPM (.0002 MM IN .5 CM BEARING) AND, IN ADDITION, WERE ABLE TO DETERMINE THE PRESENCE OF FLAWS WITH THE SAME SENSITIVITY. RECENT TESTS BY LANL, USING A JOINT LANL/QUATRO PATENT DISCLOSURE, HAVE INCREASED THIS SENSITIVITY SEVERALFOLD, HOWEVER, ...

IN MICROELECTRONICS PROCESSING DIFFRACTION GRATING TEST PATTERNS ARE CREATED ON THE WAFER FOR CHARACTERIZING A PROCESS STEP. IN THIS APPLICATION THE SHAPE OF THE LINE IS MEASURED SINCE IT IS DETERMINED BY PROCESSING CONDITIONS. COMPLETE CHARACTERIZATION OF GRATING LINESHAPE IS TEDIOUS AND OFTEN DESTRUCTIVE, SUCH AS BY USING SEM TECHNIQUES. RAPID, NON-CONTACT, NON-DESTRUCTIVE TECHNIQUES TO CHARACTE ...

THIS PROPOSAL DESCRIBES THE USE OF HOLOGRAPHIC INTERFEROMETRY TO STUDY BOTH THE MECHANICAL AND ELECTRICAL STRESS CHARACTERISTICS OF THIN POLYMER FILMS, SPECIFICALLY THOSE EXHIBITING ELECTROACOUSTICAL BEHAVIOR SUCH AS POLYUREAS AND POLYURETHANES. WE PROPOSE TO CORRELATE THE HOLOGRAPHIC FRINGE PATTERN, CREATED BY THE MECHANICAL STRESS INDUCED BY THE APPLIED ELECTRIC FIELD, TO THE CHARGE DISTRIBUTION ...
