Magnetic field sensors are currently in widespread use in military, industrial, and automotive applications. They are currently used in automobile distributors and anti-skid braking systems, and are proposed for vehicle location (wheel sensor) in IVHS systems. The utility and performance of these sensors is critically dependent on magnetic field sensitivity. This development applies Giant Magneto- ...

Ultra-Wideband (UWB) signals, much like conventional spread spectrum waveforms, minimize intercepts from unintended receivers by generating negligible amounts of energy within the intercept receiver's acquisition bandwidth. Unlike spread spectrum, UWB spread bandwidth is generated directly, not by modulation with a spreading sequence. UWB is essentially a time-domain concept in which an extremely ...

The objective of the proposed Phase II development effort is to establish a material system and robust fabrication methodology to produce ultra-refractory (UF), ceramic matrix composite (CMC) components based on C(f)/HfC90SiC10 compositions for futurescramjet combustors and nozzle liners. The proposed Phase II is split into two distinct efforts. In the first effort, a robust chemical vapor infiltr ...

A low-cost, manufacturing technology is proposed to polish, defect-free, crystallographically perfect surfaces on all economically important semiconductor and optical materials. The technology is applicable to the high-volume production of a broad range of military and commercial components requiring surface accuracies between 0.3 and 0.006 microns. The feasibility to combine precision optical pol ...

Maxion proposes to further develop epi-side-up-mounted interband cascade (IC) lasers emitting in the mid-infrared (IR) wavelength spectral region between 3 and 5 microns. Following up on a successful Phase I effort, Maxion will design, develop,and testimproved IC laser active regions that promise to lead to reductions in threshold current density and non-radiative processes including Auger recombi ...

Magneto-Thermal MRAM uses both heat and magnetic field (current) to overcome thermal instabilites of very small memory cells. Self-generated heat in the cell raises the temperature of magnetic material in the cell above the exchange ordering temperature ofthe magnetic material (either ferromagnetic or anti-ferromagnetic). Magneto-Thermal MRAM is compatible with advances in photolithography down to ...

This proposal describes an integrated research and development plan leading to a novel portable biowarfare detection platform capable of meeting all key requirements for universal pathogen detection. Effective technologies for the detection andidentification of biological warfare agents (BWAs) are of critical and growing importance. Despite ongoing advances in this area, current technologies are l ...

Emerging high-speed networking technologies have the potential to dramtically increase access to information in many fields such as education, defense, government information dissemination and health care. However, there are several technical issues that need to be addressed to harness this potential of high-speed networking technology. One ofthese is the development of a new generation of communi ...

Wireless communications with RFID tags is used for numerous tracking and identification purposes, with many new applications on the horizon. Unfortunately, low cost tages are handicapped by read-only capabilities. This limits their potential applications base, particularly in private/secure communications areas, where the ability to periodically rewrite a security code is desirable. Magnetoresisti ...

Long-duration wide-area surveillance missions increasingly are space-based. MEO orbits offer space-based radar systems more time on station, but require very large array apertures on the order of 100m in diameter. Achieving larger apertures with smaller,lighter launch packages and stable on-orbit pointing is a challenge that E-Textiles promises to meet. Textile processes can be used to achieve a l ...
