THERMOPLASTIC ELASTOMER (TPE) BY INJECTION MODLING OFFERS AN ALTERNATE METHOD FOR FORMING CHEMICAL PROTECTIVE GLOVES A SOCMPARED TO THE CONVENTONAL DIP PROCESS USING BUYTL RUBBER SOLUTIONS. THE ADVENT OF VARIOUS TPES WITH OLEFINIC, STYRENIC, URETHANE, ENGINEERING RESINS AND ALLOYS AND BLENDS OFFER THE ADVANTAGE OF INJECTION MODLING PRODUCTS WHICH HAVE BEEN CONVENTIONALLY MADE BY ELASTOMER COMPOUND ...

Improved methods for frozen storage of glycerolized red blood cells (RBCs) are needed both tomeet military and civilian needs in periods of high demand. Existing deglycerolization ssytems are labor intensive and considered "open" systems resulting in a maximum storage of 24hrs following washing. The washing of cells with flat sheet membrane filters has been proven effective by the Advanced Haemote ...

THE PROJECT WILL DEVELOP A NOVEL MINIATURE PULSE WIDTH MODULATED POWER DRIVER FOR ACTUATORS, I.E. DC MOTOR. THE POWER DRIVER WILL DELIVER 50 AT 50VDO IN A DOUBLE INON PACKAGE. THIS COMPACT DESIGN CAN ONLY BE ACHIEVED THROUGH THE INNOVATIVE COMBINATION OF MODER POWER SEMICONDUCTOR TECHNOLOGIES, PROPRIETORY CIRCUIT DESIGN, AND STATE-OF-THE-ART PACKAGING TECHNOLOGY WHICH UTILIZES NEW HEAT CONDUCTIVE ...

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 ...

Operation of cooling tower and boiler systems requires frequent monitoring of water chemistry parameters to obtain the necessary information for adjustments to the water treatment program. Failure to perform the necessary adjustments can result in reduced service life and poor energy efficiency resulting from corrosion, scale and fouling. A hybrid absorbance/emission spectrometer is proposed as th ...

A reflectiver near infrared (NIR spectrometer is proposed for the noninvasive measurement of surface and deep tissue pH. Previous experimental studies have demonstrated on a preliminary basis the ability to estimate liquide pH in complex biological matrices based on NIR spectra [Dre 90][Sch 93], and the proposed development program will design, contruct and test an experimental bench NIR pH measu ...

AS PAVEMENT MANAGEMENT SYSTEMS BECOME THE PRIMARY TOOL BY WHICH AGENCIES ALLOCATE THE FUNDS FOR PAVEMENT REHABILITATION, THE ACCURACY OF DISTRESS DATA. ONE OF THE LEAST EXPENSIVE BEING MANUAL DISTRESS SURVEYS. HOWEVER, MANUAL DISTRESS SURVEYS HAVE THEIR LIMITATIONS. INACCURACIES THAT ARISE IN THE ACCUMULATION AND SUMMARIZATION OF THE DISTRESS DATA CAN LIMIT OR IMPAIR ITS USE SIGNIFICANTLY. ONE WAY ...

Many presently fielded weapons systems as well as systems on the drawing boards, must transmit and store large volume sof digital data generated by electro-optic (EO), imaging infrared (IIR), millimeter wave (MMW) and fiber optic guidance systems. Real time data compresson offers the advantage of smaller storage devices and dat alink systems by reducing the volume of data without reducing the info ...

A programmable fiber optic delay line system for microwave signal storage will be designed and analyzed, and optical switch technology for use in the system will be perfected. The delay line will consist of fifteen 2x2 optical switches connected by single mode fiber sections of unequal length. A key component in the system is the all-fiber piezoelectrically actuated switch developed at Texas A&M ...
