This project will develop and demonstrate a prototype Modular Perfusion Bioreactor (MPB) for tissue engineering applications. While many unique styles of bioreactors have been proposed for various types of stem cell and tissue cultures, there is not a single, easy-to-use device that accommodates the multiple diverse needs of multiple tissue culture types.. In order to take advantage of recent ad ...

The InAs/InGaSb Strained Layer Superlattice (SLS) system is developing rapidly and is now finally poised to seriously challenge HgCdTe as the dominant technology for mid- and long-wave detection. SLS structures have a number of practical and theoretical advantages over HgCdTe materials, including lower Auger noise, higher operating temperature, better wavelength uniformity, more robust materials, ...

Pine Ridge Products LLC will introduce a tactical micro wind turbine that is highly efficient, robust, easy to use, maintain and transport. The Army is requesting a renewable energy system to reduce the amount of fuel used for small power loads. A vehicle mounted, efficient wind turbine system would improve self sufficiency on site by decreasing the need for fossil fuels. This will increase reliab ...

THE U.S. ARMY HAS A NEED FOR A LIGHTWEIGHT, STRONG, MOBILE BRIDGE. ONE PROBLEM THAT LIMITS THE PERFORMANCE IS THE DESIGN OF ADHESIVE JOINTS. THIS PROJECT IS TO DEVELOP SEVERAL OPTIMUM JOINT DESIGNS SO THAT THE LOADS ON JOINTS OF EITHER TUBULAR AND FLAT COMPONENTS ARE IN SHEAR, AND THE STRESS CONCENTRATIONS ARE REDUCED. THE PROPOSED PROGRAM IS TO USE THE RESEARCH WE HAVE ACCOMPLISHED IN EXPERT SYST ...

AEROMET PROPOSES TO DEVELOP A SENSOR SYSTEM FOR THE PURPOSE OF MONITORING RF FIELD STRENGTH ENERGY. PHASE I WILL CONCENTRATE ON THE DESIGN AND DEVELOPMENT OF A UNIQUE PROGRAMMABLE SENSOR THAT CAN SENSE THE ENERGY IN VARIOUS FREQUENCY BANDS. THE SENSOR WILL ACT AS A STAND ALONE UNIT AND BE POWERED BY SOLAR CHARGED BATTERIES. THE SENSOR WILL BE DESIGNED SO THAT MANY OF THEM CAN BE OPERATED IN CONJUN ...

FOR FAST RISE TIME PULSES AND HIGH POWER MICROWAVE APPLICATIONS, A NEW CLASS OF VARISTOR DEVICES IS NEEDED THAT SURPASSES THE PERFORMANCE OF PRESENT DEVICES. CURRENTLY AVAILABLE VARISTOR MATERIALS DEPEND ON SEMICONDUCTOR JUNCTIONS, AVALANCHE MECHANISMS, OR ZENER ACTION, OR A COMBINATION OF THESE EFFECTS. AN ALTERNATIVE THAT OFFERS SIGNIFICANT ADVANTAGES IN TERMS OF RESPONSE CHARACTERISTICS, RELIAB ...

CURRENTLY, THE ARMY USES WATER PURIFICATION SYSTEMS BASED ON REVERSE OSMOSIS (RO). RO IS EFFECTIVE, BUT CONSIDERABLE ENERGY IS REQUIRED TO OVERCOME THE OSMOTIC PRESSURE OF RAW WATER. ALSO, ELABORATE PRETREATMENT SYSTEMS MUST BE USED TO PROLONG THE LIFE OF EXPENSIVE RO ELEMENTS. THE ARMY DESIRES A SYSTEM THAT IS AT LEAST AS EFFECTIVE AS RO FOR WATER PURIFICATION, YET IS SMALLER, LIGHTER, MORE ECONO ...

VERY RECENTLY, THERMOPLASTIC PULTRUSIONS, INC., HAS DEVELOPED THE CAPABILITY TO PULTRUDE ULTRA HIGH-MODULUS GRAPHITE FIBER/POWDERED THERMOPLASTIC RESIN PREPREGS INTO HIGH QUALITY COMPOSITES WITHOUT DAMAGING THE FIBERS. SINCE THE PULTRUDED COMPOSITES ARE ALREADY CONSOLIDATED, REFORMING DOES NOT REQUIRE THE HIGH PRESSURES AND LONG DURATIONS TYPICAL OF AUTOCLAVE FABRICATION. HENCE, IT SHOULD BE POSSI ...
