The ongoing explosion of microwave radar and communications systems calls for improvement in electronically scanned antennas (ESAs). However, current ESAs crafted from multiple individual elements are extremely expensive. Forming an antenna with integrated scanning and impedance matching elements on a single substrate using thin film technologies may decrease costs by up to two orders of magnitu ...

The TRP-SBIR project will address the synthesis and characterization of single crystal relaxor ferroelectrics for high performance bio-medical transducers. The ability to grow single crystals of various relaxor-based compositions with specific crystallographic orientations offers piezoelectric, dielectric and electro-mechanical properties not achieveable in ploycrystalline PZT ceramics. Limitati ...

This SBIR Phase I program will address the fabrication and testing of voltage variable dielectrics (VVD) in which the refractive index (n) can be E-field tuned providing electronic scanning in the microwave regions. In collaboration with Hughes' Radar Division, the manufacturing of large area composites based on the perovskite Barium Strontium Titanate (BST) will be integrated into a continuous t ...

This SBIR Phase I program will address the fabrication and testing of pseudo single crystal relaxor ferroelectrics (PMN:PT) for high performance electromechanical actuators. In collaboration with Innovation Powder Technology, Inc. the crystallographic orientation of solid state grown PMN:PT will be controlled using hydrothermally synthesized perovskite PbTiO3. The use of large 5-10 micron platel ...

Operating temperatures for phosphoric acid fuel cells have been steadily increasing in the quest for higher efficiency. The temperature increase has been made possible by the use of more stable electrode catalyst and other fuel cell materials. This makes it possible to consider reforming methanol fuel internally, thereby improving efficiency and simplifying power plant design. This change eliminat ...

Some polymers exhibit Seebeck coefficients that are 100 to 1000 times higher than those of semiconductors used in today's thermoelectric devices. Unfortunately these polymers have low electrical conductivity that results in a figure-of-merit, ZT, that is much lower than do the conventional semiconductors. Attempts to increase the conductivity of polymers by doping or micro particle addition have ...

K2T, Inc. proposes to design and demonstrate an interactive system capable of reconstructing 3-D models from ordinary video image sequences. Although many people are currently working in the field of shape from motion, no one has yet developed a commercially viable system for reconstructing 3-D models from videotape. The objective of this Phase I research is to design such a system. The system ...

K2T proposes the development of a novel concept for using arrays of low-cost, internetted, unattended sensors to detect, localize, and classify targets in ground and littoral environments with the goal of increasing battlefield awareness. The concept will initially combine imaging, acoustic, and location sensors with local signal processing and communications capabilities; but can be expanded to ...

The accessibility of information on the Internet could be dramatically increased by providing users with meaningful semantically rich visualizations of the relationships among diverse information sources and data. However, most attempts to visualize the web have focused on its superficial structure rather than the meaning of its contents. Similarly, most current software tools provide only narro ...

Techinical Abstract: A physically small, rugged, low power, light weight X-ray imaging sensor, readout, display and transmission system is proposed which will provide an effective means for X-ray screening in General Radiology, Radiology and Fluoroscopy, Angiograpgy and Cardiology for both commercial and military applications. The system will consist of a novel flat panel R-ray detector, a high ...
