Award Data

Infrared sensors and sensor arrays are widely used in military and commercial applications such as night vision, medical diagnosis and weather mapping. Expensive quantum effect sensors, such as HgCdTe systems, must be cooled to liquid nitrogen temperatures and are difficult to produce with uniform properties. A significant opportunity exists to dramatically improve detector fabrication and perform ...

When waveguides of high power radar systems are installed in corrosive environments gaps tend to form at the joints. These gaps change the characteristic impedance of the waveguide, causing reduced system efficiency and potential damage to the radar. An indication of these gaps are arcs generated by the high power radar signals crossing the gaps. Phase I will develop and validate a technique to ...

An advanced ceramic heat recuperator (ACHR) incorporates thin corrugated,d triangular-shaped flow channels made of non-oxide ceramics with high thermal conductivity and high fracture toughness. A counterflow arrangement together with the unique design of the flow channels makes the ACHR highly efficient, highly reliable and compact. A key processing innovation is also made for fabrication of the ...

The need to transmit video information greatly exceeds the current capability to transmit this information for any many military applications. This statement is absolutely true in the teleoperation of semi-autonomous robotic land vehicles where the remote operator needs advanced video compression techniques to support low data rate and supervised driving modes. This proposal advocates the developm ...

Composite structures are lighter, stronger, and have more predictable performance than do components implemented with conventional metal structures. However, defense and industry have been slow to adopt composites components, even in application areas where firm cost justification arguments can be made, because of inexperience with composite structure failure modes and the difficulty of routine N ...

Attitude estimation of 3D objects is a necessary component of many of today's most difficult problems. Currently White Sands Missile Range (WSMR) has an application in which they wish to use live imagery from multiple video sources to precisely determine the attitude or pose of missiles, aircraft, and submunitions as they pass through the field of view. This proposal describes a system that solv ...

Transmittance pulse oximetry is currently the preferred method of noninvasive oxgenative monitoring. However, this type of monitoring is limited with regards to peripheral probe placement, creating an inability to measure deep-tissue oxygenation to the level desired. Recently reflective methods have been applied to pulse oimetry; however, the reflected signal isdifficult to measure and interpre ...
