Improved performance SWIR sensors with extended wavelength response to 2.5 microns will be developed using two disruptive technologies with which Amethyst has demonstrated success: nBn detector structures and defect passivation via hydrogenation. Similar to conventional extended wavelength photodiodes, the improved sensors will based on mismatched InGaAs grown on graded buffer layers on InP substr ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; that is, it is a direct pressure gradient imager. The imager relies on the piezo-dichroic properties of a continuous layer of a dichroic material thin film that serves as bo ...

Obesity and osteoporosis are major public health concerns due to their prevalence in our increasingly sedentary and aging society. In the U.S. today, an estimated 55% of people 50 and older are at risk for developing osteoporosis. Because as much as 20% of bone mass can be lost in the first five to seven years following menopause, osteoporosis is a major health issue for aging women. In 2005, oste ...

The agricultural community's relationship with urban centers has always been complicated and highly dynamic. Recent US Census data indicates that "agricultural America" is growing the fastest at the transition zones near urban areas. At the same time there is strong interest by those living in cities and suburbs to participate in food production and farming. In conjunction with these trends i ...

Ammonia gas that is emitted from agriculture can create health problems for workers and, surprisingly, for people far from the agricultural operation. Once released into the air, the ammonia undergoes a series of chemical reactions that lead to small particles (known as PM2.5) that are inhaled deep into people's lungs. Those particles can trigger asthma and are linked to increased risk of hea ...

Center pivot irrigation systems are widespread across the Nation's critically water short regions. A common bias for irrigators is to give crops more water than is actually needed in order to cover uncertainties and ensure enough water is present. This practice leads to profound waste of water and energy. Providing just what the crop needs is the means to achieve profound conservation that ca ...

Naval Special Warfare is developing and testing equipment and tactics for neutralization of anti-invasion mines in the very shallow water maritime environment. The device proposed herein, an electromagnetic pulse mine countermeasure device, will enhance the capability of Naval Special Warfare to neutralize mines. The proposed device is expected to be effective against most, if not all, mine types, ...

Molecular oxygen is the most critical participant in respiratory pr ocess. Adequate oxygen supply is essential for the survivals of all living species. Fast, reliable and real-time measurement of oxygen concentration (partial pressure) is of great importance in assessing the health status of a person/soldier and the timely caring of critically ill patients. Presently available oxygen sensors suf ...

The use of sub-therapeutic concentrations of anti-microbial agents in animal feed has contributed to theproductivity of the U.S. meat and dairy industries by preventing infectious diseases, by decreasing theamount of feed required and by increasing the rate of animal weight gain. However, failure to observerecommended practices of drug withdrawal can result in concentrations of antibiotic residue ...

The ready-to-assemble (RTA) construction system is a new method for assembling wood structuresbuilt from the following engineered wood products: parallel strand lumber (PSL), laminated strandlumber (LSL), and laminated veneer lumber (LVL). The RTA system is designed for rapid assemblyby small crews of unskilled labor using common hand tools. The design of the RTA systemincorporates engineered w ...
