Award Data

The recent emergence of the Silicon Drift detector (SDD), for use in Energy Dispersive x-ray Spectroscopy (EDS), has made possible x-ray event streams with input count rates in the range of 1-10 Mcps. Modern digital pulse processors are therefore required to run at fast time constants to achieve reasonable throughput; however, this causes significant coincidence artifacts to appear in the spectrum ...

A personal air ventilation system (PAVS) can dramatically improve the environment inside chemical/biological protective clothing, protecting the health and safety of soldiers and enabling peak physical/mental performance for long periods. However, existing air blowers that can produce the flow rate and pressure drop needed for a PAVS are too heavy, inefficient, and noisy for a man-portable system ...

Under this proposal, Virtual Global, Inc. proposes to work with NIST to develop RBAC-BASED WORKFLOW, a workflow system that will use RBAC in a web services model as a form of middleware that can be "packaged" accessed, configured, and reused by integrating with existing trusted RBAC implementations.

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 ...

The pressing need exists within industry to accurately measure high aspect ratio microscale structures. For example, diesel injector nozzles are manufactured with microscale holes ranging from 50-200 micrometers in diameter and 3-5 mm depths. One fundamental challenge is to nondestrucvely measure these features in order to validate models, enhance manufacturing processes, and reduce fuel emissions ...

Manning Applied Technology proposes to develop a handheld infrared spectrometer, ideally suited to detection of airborne chemical agents at and below permissible exposure limits. This approach offers unmatched sensitivity and specificity for detection of all types of chemical vapors. The instrument is modular, rugged, compact and highly sensitive. Volume pricing will be less than $1000 each. ...

The current methodology for testing the penetration resistance of textile materials to various chemical agents has a number of drawbacks, including significant uncertainties in the resulting data, inefficiency and expense, risk to test personnel, and limited range of test conditions. The objective of the proposed work is to apply unique computer models for textiles with accompanying experimental ...

Homeland Security/First Responder networks require increased bandwidth and reliable connectivity. Future networks such as Project SAFECOM may deploy software-defined radios (SDR) compatible with Joint Tactical Radio System (JTRS) Software Communications Architecture (SCA). We leverage our SCA compatible, high assurance ¿Smart Radio¿ prototype being developed under an AFRL sponsored Phase II ...

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 ...
