Leveraging existing multi-frequency antenna arrays for purposes they were not originally designed would greatly improve the benefits of such systems. For example, the use of arrays of small antennas with novel waveforms may produce low frequency signals in the far field that are not possible using single antennas and classical waveforms. In particular, we propose to investigate the formation of lo ...

Decontamination of chemical and biological threats demands a very reactive solution. It is ideal to generate the decontaminants on-site: the activated decontaminant is highly reactive and quickly destroys chemical and biological warfare agents; prior to activation the ingredients can be safely stored for years, shipped, and handled. TDA's electrochemical decontamination (eClO2) technology u ...

Current prosthetic feet produce much less peak mechanical power than the able-bodied foot/ankle and release only about half of the mechanical energy generated during gait. This leads to higher energy expenditure among amputees as compared to able-bodied i

The neurocognitive health of U.S. service members plays a vital role in the defense of the United States. It is critical to a service member"s effectiveness, to force readiness, and it is a key component of a service member"s successful reintegration into family life and society following deployment. Increased rates of mild traumatic brain injury (mTBI) and psychological health problems experien ...

SRICO proposes to combine metamaterial narrowband absorbers and SRICO-proprietary thin film lithium tantalate (TFLT) pyroelectric thermal detectors to produce ultra low cost, size, weight and power (SWaP) room temperature stand-off chemical sensors. Metamaterial narrowband absorber elements will be integrated into the TFLT pyroelectric detector process to provide conversion of radiation to heat, w ...

A narrow-band microbolometric detector is proposed to the address need for a low-cost, portable system to perform chemical and biological threat detection. An approach is shown to achieve a narrow-band bolometric detector whose response can be tailored to both a desired peak wavelength and bandwidth. The approach will enable the design of an array of detectors meeting the requirements for chemical ...

This Small Business Technology Transfer Research program will develop narrow band plasmonic resonant cavity filters with integrated microbolometer sensors operating in the long wave infrared (LWIR) atmospheric transmission band for IR absorption measurements of low concentration chemicals. IR spectroscopy can identify a wide range of contaminants, including chemical/biological warfare agents, exp ...

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 ...

The Army has a clear need for a small unmanned ground vehicle (UGV) capable of autonomously accompanying a single soldier or vehicle. Such a UGV would help solve both logistical problems of soldiers needing to transport more equipment and supplies than they can carry in a backpack, and tactical problems of scouting unsafe areas. Multiple designs for such UGVs exist; however, they require active re ...

Ransomware is terrorizing the Internet, running rampant in consumer, business, and government systems. So far, ransomware-specific defenses have had minimal impact or success. We propose a new technology called RAM Journaling, a selective recording of RAM over time. The primary purpose of the journal is the recovery of locked data. Specifically, the journal is searched for the symmetric cryptograp ...
