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 ...

Poor air quality represents a major public health risk, contributing to an estimated one of every eight deaths worldwide. Low-cost air quality sensors have developed rapidly over the last few years and offer the opportunity to make air quality monitoring widespread at an affordable price. However, low-cost sensors are currently unable to deliver accurate, reliable data due to a lack of understandi ...

Triton Systems, Inc. proposes development of the Open-Source Oceanographic Asset Recovery Beacon (OpenORB) that will allow the deployment of coastal instrumentation moorings with affordable protection against loss. This open-source kit would significantly reduce the purchase price of a commercial location beacon by allowing the end-user to assemble a customized system with minimal time and effort. ...

Clear Scientific, a wholly-owned subsidiary of Nano Terra, proposes to develop a low-cost and wearable detector badge that quickly alerts the user in real time to the presence of solid or aerosolized fentanils with an audible and visual alert. Current commercial opioid detectors are bulky, costly, and cannot be used passively in real time. Clear Scientific will leverage their expertise in ultra-se ...

Implementing continuous nuclear and radiological monitoring systems that support automatic detection and tracking of potential nuclear threats is\ntraditionally associated with a high operational burden. Sensors are typically monitored by dedicated personnel, who must investigate detection events\nin a timely manner. High nuisance alarm rates can rapidly overwhelm already taxed law enforcement per ...

BlueRISC's proposed solution provides a fundamentally new approach to automated embedded software/firmware analysis relying on a novel cross-binary/firmware differential exploitability analysis framework. The solution is able to identify newly added potentially exploitable paths associated with zero/n-day vulnerabilities, characterize new functionality with respect to its potentially malicious nat ...

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 ...

In Phase I, we developed a prototype instrument for counting, sizing and identifying both non-toxic and toxic Harmful Algal Bloom (HAB) species. We did this by integrating three innovative technologies: High-throughput color, Light Field Imaging Flow Cytometry to acquire morphological information for each cell, Raman spectroscopy to acquire species-specific molecular information on pigments and tr ...
