Job related hearing loss is a growing issue with active and retired military personnel. Ear protection is critical to prevent such injury, but personnel in variable pressure environments, such as pilots, often cannot use the best hearing protection due to pressure changes risking barotrauma. Current physiological monitoring systems can measure in-ear pressure levels, but require customized ear pie ...

In the proposed Phase II enhancement, SI2 Technologies, Inc. (SI2) proposes to build on our Phase I and II efforts and continue to develop a wideband conformal antenna suite for incorporation into and employment on small tactical unmanned aerial systems (STUAS) in support of various and selected radio payloads. The research, development, acquisition, and support of the conformal antenna suite will ...

SI2 Technologies, Inc. (SI2) proposes to build on our successful Phase I and Phase II efforts and continue to develop a wideband, electronically steered, multi-beam transmit/receive (TX/RX) array for Navy surface ship EW systems. The proposed program will focus on developing the front end receive (RX) electronics required to provide full TX/RX capability in a single multi-function aperture.In Phas ...

SI2 Technologies, Inc. (SI2) proposes to design and develop several conformal antennas for UHF flight termination , L-band data link, S band telemetry and C band tracking beacon systems for the Navy Strike Weapons. In addition, SI2 proposes anti jamming protection for S and C band antennas using frequency selective surfaces (FSS). To improve the wideband performance and significantly reduce the th ...

Greenhouse gas (GHG) emissions are primary drivers of global climate change. Hence there is a crucial need to quantify their sources and sinks. A powerful method to constrain source and sink strengths is the analysis of the relative proportions of isotopic variants of GHG’s in atmospheric samples like those collected globally by NOAA’s Cooperative Air Sampling Network. Measurements that are ca ...

This program addresses the development of non-intrusive, broad band, high sensitivity microwave electrical field sensors. Non-intrusive high frequency electrical field probes of high sensitivity have both military applications in fields of high power microwave weapon (HPM) development, and wide commercial applications. By leveraging the significant progresses of RF field sensing technologies with ...

Physical Sciences, Inc. (PSI) has developed a nanoparticle chaff that yields an ultraviolet (UV) light absorbing cloud upon dissemination from a center burster cartridge. During the Phase I program we utilized UV extinction data, Mie Scattering calculations and cloud radiance models to optimize both the chemistry and particle size for the UV absorbing material. We have demonstrated chaff cloud for ...

Leveraging on our extensive production experience in fiber optical components and fiber lasers, AGILTRON proposes to realize a new high pulse energy tunable blue laser with doped ZBLAN fiber. Based on enhanced blue upconversion by properly selected co-dopant materials, the proposed blue fiber laser will be able to generate high power. Furthermore, using beam combing technology, we will combine mul ...

When any Unmanned Underwater Vehicle (UUV) is underwater it cannot receive a GPS signal and it cannot communicate by utilizing RF. This lack of connectivity greatly impacts all operations and is a problem for all users of UUVs. Brooke Ocean Technology USA Inc. has proposed a solution, a towed buoyant antenna, that would give UUVs the ability to communicate rapidly and in real time while submerged. ...

Physical Sciences Inc. (PSI) and the University of Connecticut propose a Phase II program to develop enrichment processes for concentrating the rare earth elements (REE) content of a novel, low cost, and abundantly and readily available industrial waste material in the United States. This material has not previously been considered as a domestic REE source. In Phase I, laboratory scale experiments ...
