The widespread use of communication devices and radar systems has made our society increasingly vulnerable to disruptive, high-power, short pulse electromagnetic interference (EMI) and high power microwaves (HPM). Significant advances in devices thatproduce these high-power, short pulses have been made in the US and abroad in the past few decades. As a result, the need for devices that can prote ...

DESCRIPTION (provided by applicant): Galactosemia is a potentially lethal, but preventable, disease of newborns. In Phase I of this grant, we demonstrated that a 13C-galactose breath test could be used to assess the degree of impairment of whole body galactose oxidation in more than 90 galactosemic children with a broad spectrum of mutations in the human GALT gene that codes for galactose-l-phosph ...

DESCRIPTION (provided by applicant): EIderly falls constitute one of the most costly health problems in the U.S., both in terms of expense to the healthcare system and in individual suffering. Fully one-third of people over age 65 fall each year, many incurring significant injuries that strongly impact their long-term health prospects and productivity. Although many factors contribute to the prop ...

DESCRIPTION (provided by applicant): Zirconia bio-ceramics (e.g. Prozyr) have the highest toughness and strength compared to other bio-ceramics such as alumina (e.g. Biolox) or zirconia-toughened alumina (Biolox-Delta). However, as highlighted by the recent recall of St. Gobain zirconia heads, a critical need remains to develop bio-ceramics with both significantly reduced wear characteristics and ...

DESCRIPTION (provided by applicant): Vitamin D deficiency is now recognized as a significant health problem for middle-aged and older adults. Vitamin D deficiency exacerbates osteoporosis and causes the bone disease, osteomalacia. Vitamin D deficiency increases risk of skeletal fractures. It is well known that the ultraviolet B portion of the solar spectrum is responsible for the cutaneous product ...

Digital Beamforming (DBF) technology offers several advantages to phased-array radar and communication systems over previous analog phase shifters including performance, versatility and cost. Previous array phase-shifter technology can be classified aseither fixed delay, employing switched delay lines, or variable delay, using ferrite phase shifters. The fixed-delay systems suffer from lack of ver ...

Phased-array radar employing wideband digital beamforming (DBF) offers the potential for detecting and tracking incoming cruise missiles while defeating electronic countermeasures such as chaff, jamming and anti-reflective coatings. A wide instantaneousradar bandwidth is essential for defeating these threats, resulting in improved range resolution and target signature. Digital beamforming may be u ...

A unique approach to the problem of portable signal identification training (PSIT) is proposed through the use of an integrated signals database, training software, and the re-use of operator interface software. Two training scenarios are addressed:standalone training mode and transmit training mode. The proposed approach is based entirely on COTS hardware. The approach also minimizes the hardw ...
