THIS PROPOSAL IS BROKEN INTO FOUR PROJECTS. THE FIRST PROJ-ECT IS THE IMPLEMENTATION OF A QUICK RETRIEVAL SYSTEM FOR LASER DISCS THAT WILL ALLOW USERS TO RAPIDLY ACCESS LARGE AMOUNTS OF DATA VIA INTERNAL COMPUTER CONTROLLED HASHING TA-BLES EITHER STORED ON THE LASER DISC OR MAINTAINED VIA MAIN-TENANCE SOFTWARE ON OTHER SOTRAGE MEDIA. THE SECON PROJECT CONSISTS OF A LIBRARY OF SUBROUTINES TO ACCESS ...

THE OBJECTIVE OF THIS EFFORT IS TO ASSESS LIGHTWEIGHT STRUCTURAL COMPOSITE MATERIALS WITH GREATLY IMPROVED FLAMMABILITY, SMOKE GENERATION, AND TOXIC FUME GENERATION (FST) PROPERTIES FOR USE IN NAVY INTERNAL SUBMARINE APPLICATIONS. THE MATERIALS TO BE EVALUATED CONSIST OF GLASS REINFORCING FIBERS BLENDED IN A THERMOPLASTIC MATRIX WITH PRECISE FIBER/RESIN VOLUME FRACTION CONTROL. THE THERMOPLASTIC ( ...

THIS PROJECT WILL PREPARE FOR EVALUATION A MATERIAL WHICH SHOULD DEMONSTRATE SUPERIOR PERFORMANCE IN ABSORBING AND DISSIPATING EXPLOSION SHOCK ENERGY. THE COMPOSITION PROPOSED AND ITS BASIS FOR PERFORMANCE ARE EXPLAINED. SHOCK WAVE TESTING WILL BE UNDERTAKEN; AND BASED ON THE RESULTS, RECOMMENDATIONS WILL BE MADE FOR FUTURE PROJECT DIRECTION.

THE OBJECTIVES OF THE PROPOSAL EFFORT ARE TO IMPROVE THE RELIABILITY AND TO REDUCE THE FABRICATION COSTS OF SINGLE MODE FIBEROPTICS COUPLERS BY: 1. DEVELOPING THICK, SINGLE MODE WAVEGUIDES WITH IDENTICAL CROSS SECTIONAL PROFILE MATCHING THAT OF SINGLE MODE FIBERS; AND 2. LOCATING THESE FIBERS TO WAVEGUIDES, MADE OF ELECTROOPTIC MATERIAL, USING PREALIGNED ETCHED "V" GROOVES IN A GAAS SUBSTRATE. OUR ...

FOR PHASE I, AMSI PROPOSES TO IDENTIFY AND ESTABLISH THE TECHNICAL FEASIBILITY OF VARIOUS ADVANCED ACOUSTIC ARRAY CONCEPTS. THREE GENERIC APPROACHES ARE CURRENTLY IDENTIFIED: 1) OPTIMIZE THE SENSOR DESIGN (I.E., DIRECTIONAL SENSORS, ETC.), 2) OPTIMIZE HYDROPHONE/ GROUP/ARRAY GEOMETRY (I.E., MULTI-APERTURES, ETC.), AND 3) IMPLEMENT SIGNAL PROCESSING TECHNIQUES (I.E., VARIOUS ANALYTIC CONTINUATION T ...

N/A

THE NAVY DESIRES TO ELIMINATE GASOLINE TO FUEL REMOTELY PILOTED VEHICLES BECAUSE OF GASOLINE'S LOW FLASH POINT AND RELATIVE UNAVAILABILITY ABOARD SHIPS. THE NAVY REQUIRES ENGINES IN THE 25 TO 35 BHP RANGE, WEIGHING LESS THAN 20 POUNDS, THAT ARE FUELED BY JP-5 AND/OR DIESEL FUEL, THAT WILL START AND OPERATE RELIABLY AT -40 DEG. F AND THAT HAVE REASONABLE FUEL CONSUMPTION CHARACTERISTICS UNDER BOTH ...

FUTURE MILITARY AVIONICS SYSTEMS WILL BE DEPENDING MORE ON BUILT-INTEST (BIT) FOR FAULT DETECTION AND ISOLATION TO MEET STRINGENT RELIABILITY, MAINTAINABILITY, AND SUPPORTABILITY GOALS. RECENT EXPERIENCE INDICATES THAT BIT IS NOT MEETING SPECIFICATION REQUIREMENTS IN FIELD OPERATIONS, EXHIBITS A HIGH FALSE ALARM RATE, HAS LOW RELIABILITY, AND IS UNABLE TO ISOLATE FAILURES TO A SINGLE MODULE. AS A ...

THE NAVAL UNDERWATER SYSTEMS CENTER HAS A CLEAR NEED FOR DETECTING AND CLASSIFYING ACOUSTIC SIGNALS. THESE SIGNALS MAY REPRESENT SHIPPING TRAFFIC, NATO NAVAL ACTIVITIES,, BIOLOGICALLY GENERATED SIGNALS (SUCH AS PRODUCED BY WHALES AND OTHER MARINE LIFE), ENVIRONMENTALLY GENERATED SIGNALS (CRACKING OF GLACIERS, ETC.), OR HOSTILE MILITARY ACTIVITY. SOME OF THESE SIGNAL SOURCES CAN BE MODELED FAIRLY W ...

IT IS PROPOSED TO USE PHASE I TO ASSESS THE APPLICABILITY OF A NEW ULTRASONIC HEAD-TRACKER SYSTEM DEVELOPED FOR HELICOPTER USE BY AEG, A PROTOTYPE OF WHICH COULD BE MADE AVAILABLE TO W.W. GAERTNER RESEARCH, INC. FOR THIS TEST. IF THE ACCURACY OF THE ORIGINAL PROTOTYPE IS NOT ADEQUATE, SEVERAL DESIGN IMPROVEMENTS ARE SUGGESTED WHICH COULD BE IMPLEMENTED UNDER PHASE II.
