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 ...

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 ...

Execution of long-range weapons capabilities reduces risk and affords greater warfighter protection. Core enabling technologies for hypersonic projectiles include high-strength lightweight materials, precision avionics, and novel designs. System demands include the ability to withstand both high accelerations (up to 50,000 Gs) and aerothermal shock. Detailed structural engineering and shock modeli ...

SI2 proposes to leverage prior Government funded efforts to develop a transmit (TX) only, wideband (6:1 bandwidth), low-cost, scalable active electronically scanned array (AESA) that will utilize phase-only nulling to enable radar, Electronic Warfare / Electronic Attack (EW/EA), Information Operations (IO) and other capabilities on multiple platforms across DOD agencies. The array will employ digi ...

Airborne radars operating over open water must classify maritime vessels by measuring and exploiting highly-variable radar signatures. Sources of signature variability include within-class ship construction and equipment differences, complex in-situ 6-DoF ship motion caused by ocean waves across a range of sea state conditions, acquisition geometry including grazing angle and maritime-specific RF ...

Deep Neural Networks (DNNs) are becoming widely used in the DoD for image classification, but recent research has shown DNNs are vulnerable to adversary attacks. Adversaries can monitor the DNN training and classification processes to learn attributes of the training data and the DNN. With this information, an adversary can gain valuable insight into the potentially sensitive data used to train th ...
