MAJOR AIDS TO NAVIGATION (ATON) ARE ESSENTIAL SIGNPOSTS FOR SAFE PASSAGE ALONG COASTAL AND OFFSHORE SEAWAYS. PRESENTLY, THEIR SIGNALS ARE POWERED BY ON-SITE ENGINE GENERATORS REQUIRING CONSIDERABLE AND COSTLY MAINTENANCE. ATON AUTONOMY WILL BE GREATLY INCREASED WITH DEEP DISCHARGE BATTERY TECHNOLOGY PROVIDING THAT ON-SITE CHARGING SOURCES ARE USED. AMONG NATURALLY AVAILABLE SOURCES, THE UNCEASING ...

THE UNITED STATES COAST GUARD (USCG) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFTEY FROM FIRE ONBOARD SHIPS. THE DEVELOPMENT OF SUPERIOR FIRE RESISTANT COATINGS FOR GLASS-REINFORCED POLYMERIC (GRP) COMPOSITES, WHICH MAY BE USED AS BULKHEADS, DECKS AND INTERIORWALLS, IS ONE WAY TO ADDRESS THIS PROBLEM. THE COAST GUARD, OTHER GOVERNMENT AGENCIES (E.G., THE U.S. NAVY) AND NUMERO ...

THE FEDERAL AVIATION ADMINISTRATION (FAA) HAS LONG BEEN INTERESTED IN THE MITIGATION OF HAZARDS TO LIFE SAFETY FROM FIRE ONBOARD COMMERCIAL AIRCRAFT. THE DEVELOPMENT OF SUPERIOR FIRE RETARDANT (FR) ADDITIVES FOR POLYMERIC MATERIALS, WHICH MIGHT BE USED IN THE INTERIORS OF AIRCRAFT, IS ONE WAY TO ADDRESS THIS PROBLEM. THIS PROPOSED PROGRAM WILL EXAMINE THE EFFICACY OF CURRENTLY AVAILABLE FIRE RETAR ...

BLADDER TYPE DEVICES ARE USED TO MITIGATE FLUID LOSSES FROM RUPTURED STORAGE DEVICES.

A new laser protective material for protection from battlefield lasers is proposed. The material utilizes novel polarizing metal spheroid film (MSF) coatings which function as wavelenght-tuned polarizers in the spectral band from 400 nm to 2200 nm. Each MSF coating can be disigned to place the peak absorption at specific laser wavelengths in this band while maintaining normal transmission at lon ...

The Advanced Traffic Controller (ATC) goal of a standard open architecture for traffic engineering applications will be more fully realized by the transition from proprietary operating system to open source Linux. In Phase I of this project, Precision Traffic Systems (PTS) demonstrated that a real time Linux OS could support an existing traffic signal control application, and perform to 2070 task ...

The goal of the Advanced Traffic Controller (ATC) program to create an open-architecture general computation platform for traffic engineering applications will be more fully realized by the transition from proprietary operating systems to open source Linux. The use of hard real-time Linux will maintain current levels of operational performance while enabling the use of newer and more powerful har ...

A PROGRAMMABLE DEFECT SIMULATOR IS NEEDED TO TEST ULTRASONIC RAIL FLAW DETECTION SYSTEMS. CALIBRATION STANDARDS CAN BE DEVELOPED WITH VARIABLE PHYSICAL CHARACTERISTICS ACCORDING TO A PREDESCRIBED SCHEME THAT SIMULATES COMMONLY-OCCURRING FLAWS (CROSS-HEAD FATIGUE CRACKS) IN RAILWAY SYSTEM RAILS. THIS PROJECT WOULD DEVELOP A METHOD OF ALTERING THE EFFECTIVE REFLECTIVITY OF A SOLID-GAS INTERFACE THRO ...
