COMMERCIAL AND GOVERNMENT SPACE TRANSPORTATION SYSTEMS DEPEND ON GROUND SUPPORT FOR NAVIGATION. THE GROUND SOLUTION CAN BE COSTLY AND MAY PROVIDE LESS ACCURACY THAN NEEDED. A GPS-BASED REAL-TIME AUTONOMOUS SPACECRAFT NAVIGATION SYSTEM IS PROPOSED. AN ALGORITHM WILL BE DEVELOPED WHICH COMBINES GPS-DERIVED POINT POSITION ESTIMATES WITH A PROPAGATED A PRIORI POSITION ESTIMATE. THE POINT POSITIONS ARE ...

1The Navy has been investigating membrane distillation (MD) as a means of desalinating seawater aboard ships since 1983. MD could potentially offer advantages over conventional distillation, the technology in most common use now, and could offer an alternative to other promising membrane technologies such as reverse osmosis. These potential advantages include small size, simplicity, and low energy ...

Microbiologically influenced corrosion (MIC) of most industrially utilized alloys, including those used in many Naval installations, is well established. However, the diagnosis of MIC type corrosion is often difficult to make using the techniques commonly employed requiring large amounts of tiem and money and "expert opinion". Ther is a need for a less subjective indicator of MIC. The work of seve ...

TAMM RELATES TO TWO TECHNOLOGIES FOR NONINVASIVE TRANSCUTANEOUS MEASUREMENTS OF BLOOD ANALYTES THAT HAVE POTENTIAL FOR APPLICATION IN A COMBAT CASUALTY CARE ENVIRONMENT. THE NEAR INFRARED (NIR) REFLECTANCE TECHNOLOGY DETERMINES BLOOD ANALYTE CONCENTRATION BASED ON DIFFUSE REFLECTANCE MEASUREMENTS WITH A FIBER OPTIC PROBE. SPECTRAL DATA ACQUIRED IS PROCESSED USING SOPHISTICATED PATTERN RECOGNITION ...

A NEED EXISTS TO MONITOR VIBRATION IN HIGHWAY BRIDGES. IT IS DESIRABLE TO MONITOR MANY POINTS ON THE BRIDGE. THE CURRENT PROBLEM IS THAT SENSORS MUST BE WIRED TO A CENTRAL LOCATION. WIRE IS DIFFICULT TO INSTALL AND TO MOVE. THE SOLUTION IS TO COLLECT SENSOR DATA BY RADIO. A SYSTEM EXISTS THAT ELIMINATES WIRE. IT GATHERS SENSOR DATA TO A CENTRAL LOCATION BY RADIO. THE SYSTEM'S UNIQUE FEATURE IS THA ...

SEVERAL CONCEPTS ARE PROPOSED FOR LOCOMOTIVE CAB ALERTERS THAT CAN BE RETROFITTED TO ALERTER SYSTEMS ALREADY IN SERVICE. THE CONCEPTS INCLUDE A TOUCH SCREEN, WHICH REQUIRES TOUCHING A TARGET TO RESET THE TIMER OR TO RESPOND TO THE ALERTER LIGHT PROMPT. THE INITIAL LOCATION OF THE TARGET ON THE SCREEN IS AUTOMATICALLY SELECTED AT RANDOM. ANOTHER CONCEPT IS THE USE OF A TELEPHONE KEYPAD WITH LCD, WH ...

The integrity of rubber-to-metal bonds is an area of reliability concern, particularly in systems that are exposed to the harsh conditions of the marine environment. Accelerated life testing (ALT) is a technique used to obtain reliability data in a compressed time frame, allowing lifetime performance predictions and failure mode analyses to be made prior to equipment installation. By performing ac ...
