A novel coating technology is proposed for increased wear and improved li fe and reliability of commutator bars in electrical sliding devices found in manned and unmanned underwater vehlilles. Diamond-Like Nanocomposite (DLN) coatings represent a famil Of thiWrfilms that bxhibit unique combinations of technologically interesting properties including high adhesion to virtually any substrate (inclu ...

THE PHASE I PROGRAM WILL BE DIRECTED TOWARD THE DEVELOPMENT OF A HIGH-TEMPERATURE, HIGH-SPEED TURBINE WHEEL DRIVEN BY HIGH-TEMPERATURE COMPRESSED AIR. CONCEPTS AND DETAILS WILL BE FORMULATED AND DESIGNED WITH REGARD TO EFFICIENCY, WEIGHT, COST, OPERATING PARAMETERS, AND RELIABILITY. OVERALL SIZE OF THE TURBINE WHEEL WILL BE LESS THAN 8 INCHES IN DIAMETER. TURBINE WHEEL/NOZZLE CONFIGURATIONS WILL B ...

CONAX HAS EXTENDED THE EXPERIENCE GAINED IN 14 YEARS OF ENGINEERING AND MANUFACTURING ELECTRICAL PENETRATORS TO SEALING DEVICES FOR FIBER OPTICS. FIBER OPTIC PENETRATORS WITH A TOTAL OPTICAL LOSS OF 0.3 DB AT 10,000 PSI HAVE BEEN DEMONSTRATED. AN INNOVATIVE USE OF COMPRESSIVE SEALING IS PROPOSED TO DEVELOP A PENETRATOR FOR SINGLE MODE FIBER WHICH IS MORE RUGGED AND HAS A WIDER OPERATING TEMPERATUR ...

U.S.M.C. CURRENT MUST MAINTAIN TWO SEPARATE SYSTEMS FOR MID AIR REFUELING; A LOW SPEED SYSTEM FOR HELICOPTERS AND A HIGH SPEED SYSTEM FOR JETS. THIS STUDY PROPOSES A RETROFIT TO EACH SYSTEM FOR DUAL PURPOSE FUNCTIONS.

THE NUMBER OF STABLE, INEXPENSIVE ANODE MATERIALS AVAILABLE FOR THE ELECTROSYNTHESIS OF CHEMICALS IS QUITE LIMITED. A SERIES OF HIGH SURFACE AREA CARBONS AND GRAPHITES ARE PROPOSED AS NEW ANODE MATERIALS FOR A VARIETY OF ELECTROCHEMICAL PROCESSES. THESE MATERIALS HAVE BEEN FOUND TO BE STABLE IN STRONGLY ACIDIC MEDIA AT HIGH OXIDATION POTENTIALS. THE EFFECTIVENESS OF THE HIGH SURFACE ELECTRODES VS. ...

THE FEASIBILITY OF DEVELOPING AN EXTREME STABLE, SPECTRALLY NARROW (150 MEZ), HIGH REPETITION RATE (30 KHZ) TUNABLE DYE LASER OSCILLATING IN A SINGLE LONGITUDINAL MODE OVER THE ENTIRE RANGE OF THE DYE IS EXAMINED. THE EXTREME SHORT CAVITY (5 CM), LONGITUDINAL PUMPED GRAZING INCIDENCE DYE LASER DESIGN OF THE PROPOSED SCHEME PROVIDES MANY DISTINCT ADVANTAGES. THE SHORT CAVITY DESIGN NOT ONLY SUPPORT ...

THE INTEGRATION OF OPTICAL CAM SYSTEM PARAMETERS DIRECTLY INTO OPTICAL CAD PROGRAMS IS EXAMINED. WITH OPTICAL CAM SYSTEMS EMERGING, IT IS IMPORTANT TO BE ABLE TO REPRESENT THE FAMILY OF SURFACES WHICH CAN BE PRODUCED ON THE OPTICAL CAM IN AN OPTICAL CAD PROGRAM. MATHEMATICAL MODELS WILL BE DERIVED WHICH REPRESENT THE POSSIBLE OPTICAL SURFACES IN TERMS OF A CAM SYSTEM'S OPERATING PARAMETERS. SENSIT ...

THIS PROPOSAL ADDRESSES THE NEED TO PROVIDE AN AUTOMATIC BEST SOURCE SELECTION OR BEST DATA ESTIMATE FOR UP TO SIX SPACE-DIVERSIFIED SOURCES OF TELEMETRY DATA. AN AUTOMATED BEST SOURCE SELECTOR IS PROPOSED WHICH MEETS THE REQUIREMENT WITH THREE OUTPUT MODES; A BEST SOURCE SELECTION, A BEST ESTIMATE VIA MAJORITY VOTING, AND COMBINED MODE WHICH AUTOMATICALLY OUTPUTS THE BEST SOURCE WHEN AT LEAST ONE ...

THE PROPOSED PROJECT WILL DEVELOP A PLAN FOR IMPLEMENTING AND EVALUATING ADA AS THE SOFTWARE LANGUAGE ON MAJOR TRAINING SYSTEMS ACQUISITIONS WHICH INCORPORATE DISTRIBUTED MICROPROCESSORS AS THE SIMULATION SYSTEM. MANY IMPLEMENTATION ISSUES HAVE BEEN DEFINED FOR SINGLE MICROPROCESSOR REAL-TIME SYSTEMS PROGRAMMED IN ADA AND SOME SOLUTIONS ARE BEING DEVELOPED. HOWEVER SIMILAR DEFINITIONS AND SOLUTION ...
