Physical Science Inc. (PSI) will develop a new approach to chemical vapor detection based on a novel open-path sample cell design. The PhaseI system level model predicts SNR supporting a probability of detection of 95% and a MTBFA of 168 hours for all relevant CWAs and TICs at the10 minute negligible MEG level at a 20 s measurement time. In addition to robust detection, the system design can provi ...

Chemical, Biological, Radioactive and Nuclear (CBRN) protective ensembles are widely used by the US Military and civilian first responders as the first line of defense for personnel working in contaminated environments. Many innovative products have been developed for the chemical protective clothing market in response to demand from the market place for improved performance. However, the need for ...

The standard US military treatment for nerve agent exposure is application of up to three autoinjectors, each containing atropine sulfate and 2-pralidoxime, to counteract symptoms of nerve agent intoxication and restore acetylcholinesterase activity. This treatment increases survival rates after nerve agent exposure, however, seizures resulting from nerve agent poisoning are a common symptom that ...

This Phase-II SBIR proposal directly addresses the need to improve the size, weight and power, SWaP, of optical cryocoolers. In particular, the proposers will work toward increasing the efficiency of optical cryocoolers by incorporating cooling materials that require less input laser power to achieve a given heat lift. The new cooling materials will be high-purity crystals doped with active rare-e ...

Physical Sciences Inc. will develop a Tomographic Digital Holographic Microscope with integrated Infrared spectromicroscopy (T-DHM/IR) to enable time resolved correlation of chemical and 3D structural properties of biological warfare agents (BWAs), microorganisms and infected human tissue. The T-DHM/IR uses a precision hexapod stage and a custom reflective microscope objective with NA = 0.83 to pe ...

Military respirator masks provide the Warfighter with life critical protection against chemical, biological, radiological, and nuclear (CBRN) threats. To ensure the safety, comfort, and effectiveness of the American Warfighter, it is essential that every Warfighter be assigned a respirator that is properly sized and fitted. However, current methods for sizing and fitting respirators depend on manu ...

In addition to military scenarios, many environmental inhalant hazards exist in the workplace, from industrial sites to medical facilities. Frequent training and practice are an essential component of effective protection, yet valid methods for assessing proper mask fit are usually not provided beyond the minimum requirements and there is a significant lack of mask fit training to ensure that prop ...

There exists a challenge in observing laser designated targets in full daylight conditions for currently fielded near-infrared (NIR) laser designators. The visibility difficulty arises primarily from the significant background signal produced by the sun, which closely mimics the spectral signature of a blackbody . By extending the wavelength region in which laser designators/markers operate into t ...

MaXentric proposes the GAU2x2 wideband power amplifier system. The design combines MaXentric’s wideband RF PA technology with advanced digital signal processing in a single small footprint package. This tight integration is made possible through the extremely high efficiency and low power dissipation. Since very little power is dissipated as heat, the package and heat sink size can be minimized. ...

While individual instances of Chemical/Biological (CB) detection sensor technology development have progressed steadily, deficiencies remain. An integrated multi-sensor network for CB detection is a promising concept for improving performance. New development is needed to address the complex challenge of how to optimally deploy and evaluate CB sensor networks to ensure maximum utility against an e ...
