The objective of this program is to develop a wide field of view spectral imaging sensor to support theater surveillance and intelligence. The AHS operates in the Mid Wave Infrared (MWIR) band and provides day/night spectral target cueing, geolocation and identification of hot battlefield threats. Currently deployed EO sensors can measure broadband MWIR signals, but are incapable of providing adva ...

Taggants are small objects used to label things or people that need to be traced. Synthetic DNA Taggants are ideal for this, since very small amounts can be detected if the sequence is known, and can be disguised by natural DNA in the environment. Known protocols for DNA amplification (e.g. PCR) allow for very sensitive DNA detection, but suffer from disadvantages: the apparatus is not very portab ...

ABSTRACT: Spacecraft power management relies upon DC-DC converters to provide multiple voltages from the storage battery. Currently available converters have shortcomings in areas of power density, tolerance to radiation and wide operating temperatures, and excessive development cost. We propose to develop a high density power converter that is compatible with spacecraft operational environments a ...

DNA microarray technology, in combination with statistical and predictive modeling tools, could be used to evaluate thousands of genes against distinct gene expression patterns induced by chemical/biological agents to provide early identification and speed therapeutic intervention. The overall objective of this Phase II effort is to leverage existing public domain resources and commercial tools t ...

Current depot-level manufacturing systems are not responsive to changing requirements and flexible specifications. The serial arrangement of individual work cells results in a lengthy timeline to complete the critically-needed part; thus, critical assets

Inspection of inserted compressor blades is difficult due to the complicated geometry of the blades, the need for high accuracy, and the safety risk posed by undetected cracks. At present, the time and cost associated with airfoil inspection forces many

High pressure compressor blades are subject to damage due to debris strikes and warping due to the elevated pressures and temperatures within the engine. Blade repair is currently performed manually using grinding to blend out the damaged regions. Reliance on manual grinding operations requires highly skilled operators, fails to reach the optimal blade shape, lacks repeatability, and is extremel ...

Three-dimensional woven and braided fiber architectures provide important advantages to composites, including suppression of delamination, high damage tolerance, improved through-the-thickness properties, simplicity and cost-effectiveness of manufacturing complex composite structural components. However, in order to diversify applications and reach high volumes of utilization of these materials in ...

Effective collective protection fabrics must have a reliable closure system. During our Phase I Work Plan, Sigma-K began developing a Hermetic Textile Closure Hardware (HATCH) system. The HATCH combines both a magnetic and geometric self locking mechanism that will provide a hermetic seal when closed. Our current Phase I successes include developing self closing samples that can provide a hermetic ...

THE OBJECTIVE OF THIS PROPOSAL IS TO CONDUCT PRELIMINARY TESTS ON A NOVEL CHEMISTRY WHICH COULD RESULT IN THE PRODUCTION OF A LOW COST WAFER WHICH CHANGES COLOR UPON EXPOSURE TO WARFARE GASES (WG). SIMILAR WAFERS WHICH WE DEVELOPED FOR OTHER GASES ARE ABOUT 2" X 1" X 1/16" AND WEIGH ABOUT 2.3 GM. THESE CHROMOSENSE (TM) WAFERS CAN DETECT HYDROGEN SULFIDE, ETC. IN 10-30 SEC. AT CONCENTRATIONS OF THE ...
