THE PURPOSE OF THE PROPOSED RESEARCH EFFORT IS TO INVESTIGATE THE FEASIBILITY OF SUPPLYING APPROXIMATELY 1 WATT OF ELECTRICAL POWER FOR ONE YEAR ON THE SEA BED WITH A NOVEL BATTERY, THE ROPE BATTERY. THE PROPOSED BATTERY WOULD LOOK VERY MUCH LIKE SMALL DIAMETER WIRE ROPE, POSSIBLYHUNDREDS OF FEET LONG. THIS UNUSUAL SHAPE PERMITS THE ROPE BATTERY TO TAKE FULL ADVANTAGE OF THE VASTNESS OF THE OCEAN ...

THERE IS AN INCREASING NEED FOR LONG RANGE (200KM) APPROXIMATELY 10 BPS RATE ACOUSTIC COMMUNICATION AT LOW BIT ERROR RATES IN THE COMMAND AND CONTROL OF ACOUSTIC SURVEILLANCE SYSTEM ELEMENTS, UNDERWATER VEHICLES AND SENSORS. SIMULATED FISH NOISE, CODED TONE AND MULTITONE CW SIGNALS HAVE BEEN USED WITH VARYING SUCCESS. ONLY THE M-ARY, MULTITONE, LONG BAND LOW FREQUENCY WAVEFORMS ARE PRACTICAL FOR L ...

COMMAND IN GROUNDD COMBAT INVOLVES MANY DIFFICULT DECISION-MAKING TASKS. A HIGHLY PROMISING ROUTE FOR ASSISTANCE TOTHE COMMANDER IS USEOF COMPUTERS. BY 1985-87 GREAT COMPUTATIONAL POWER WILL BE AVAILABLE IN LAP-SIZED MACHINES; HOWEVER, SUBSTANTIAL ADVANCES IN SOFTWARE ARE NECESSARY IF THIS PROMISE IS TO BE REALIZED. IN THIS PROPOSAL, DEFENSE SYSTEMS, INC. (DSI) DESCRIBES RESEARCH WHICHWILL LEAD TO ...

EXISTING LONG-LINE FIBER OPTIC LINKS UTILIZE VARIOUS LASER DIODES AS SOURCES; GRADED - INDEX, FUSED - SILICA CORE FIBERS AS THE TRANSMISSION MEDIA; AND PHOTO-DETECTING DIODES AS THE RECEIVING DEVICE. BY 1990 IT IS ESTIMATED THAT 10 PERCENT OF THE TOTAL COMMUNICATIONS CABLE INDUSTRY WILL UTILIZE THIS TRANSMISSION METHODOLOGY AS THE CONVENTIONAL, TWISTED WIRE PAIR WILL BE 10 8TH POWER TIMES MORE EXP ...

WHAT IS BEING PROPOSED IS THE DEVELOPMENT OF PERMANENT MAGNET BRUSHLESS DC MOTORS USING NEODYMIUM BORON IRON AS THEPERMANENT MAGNET MATERIAL. THIS MATERIAL, NEWLY INTRODUCED AT THE MMM CONFERENCE IN PITTSBURGH ON NOVEMBER 10, 1983, SEEMS TO HOLD THE POTENTIAL FOR SIZE WEIGHT REDUCTIONS FOR A GIVEN LEVEL OF OUTPUT OVER ANY OTHER PM MATERIAL CURRENTLYAVAILABLE INCLUDING RARE EARTH COBALT MAGNETS AND ...
