Built upon the progress in Phase I period, Winchester Technologies, LLC is pleased to propose to investigate practical magnetoelectric antennas during the Phase II period based on solidly mounted resonators (SMR), which will have enormous impacts on DoD and civilian antenna applications. State of the art antennas suffer from three major open challenges: (1) large antenna size > ?0/10, (2) antenna ...

Physical Sciences Inc., in cooperation with University of Notre Dame, will develop a method for the persistent detection of aerosolized biological warfare agents using a distributed and cooperative sensor network within a Bayesian framework. The proposed system, named BioNet, will provide a wider coverage and two-fold reduction in false alarm rate over individual sensor performance through intelli ...

In this Phase II effort, Zeteo will further develop over-the-ear and in-ear canine hearing protection device prototypes. These devices will combine passive hearing protection with active noise cancelation. The devices will also have a communication channel to allow the handler to communicate with the dog. Design requirements evolved from Phase I will be used to design over-ear and in-ear configura ...

The proposed SBIR program will employ Physical Sciences Inc.’s (PSI) unique ground-based high altitude plume signature simulation facility to examine the interactions of hyperthermal oxygen atoms with specific plume constituents believed to contribute to plume emission in the ultraviolet and visible spectral regions. These reactions will include the multi-step O + CH4 reaction predicted to produ ...

Airworthiness assessments of software-intensive based systems in aviation cannot be limited to verification and testing of the end product, i.e. computer code, since other factors can have an important effect on safety and integrity. Current methods and tools have limitations that do not adequately address the issues affecting the growth in complexity and cost of system development and certificati ...

Physical Sciences, Inc. and Colorado State University will advance the technical maturity of the Compressive Sensing Hyperspectral Imager (CS-HSI) platform. The CS-HSI operates in the longwave infrared (LWIR) spectral range with a single-pixel architecture for low-cost, standoff wide area Early Warning of chemical vapor plumes. The motivation for applying CS to LWIR HSI is to eliminate the high-co ...

Factors such as an increase in global antibiotic availability, inadequate treatment of wastewater from pharmaceutical manufacturing facilities, uncontrolled or over-the-counter antibiotic sales, and high antibiotic use in livestock feed have led to the rapidly-developing threat of antibiotic resistant bacteria (ARB). This rise in infection incidence from pathogens resistant to our main medical def ...

Perfluoroalkyl substances (PFASs) have been identified as a serious health contaminant in water at levels between 12 and 516 parts per trillion by the Agency for Toxic Substances & Disease Registry. In 2016, the EPA set a lifetime health advisory of 70 parts per trillion for two PFASs, perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). These compounds come from a variety of so ...

Human exposure to polyfluoroalkyl substances (PFAS) has been linked to cancer, elevated cholesterol, obesity, immune suppression and endocrine disruption. The EPA has set a PFOA health advisory of 70 parts-per-trillion. Due to widespread use of PFAS in aqueous film-forming foam (AFFF) to fight fuel fires, millions of gallons of PFASs have been used at oil refineries, military bases, civil aviation ...

Due to increasing concerns over long-term effects of PFOS and PFAS on human body, health based values were set by regulatory authoritative bodies for drinking water standard. Currenty lab-based PFOA and PFOS water tests cost $200-$300 per sample with a turnaround time of 2-3 weeks. In this program, 2W iTech LLC proposes to develop a low-cost fieldable sensing technology for detecting trace amounts ...
