The objective of the proposed SBIR program is to develop and commercialize high-temperature optical sensors using sapphire fibers for process control feedback in the fabrication of titanium-based metal matrix composites. Sapphire fiber interferometers will be designed to map the internal distribution of strain and temperature in titanium matrices durng processing, to optimize processing so that re ...

Smart Materials promise new opportunities for the implementation of adaptive structures. Smart Materials are a new class of materials that incorporate sensor, actuator and adaptive signal processing functions. These structurally and functionally integrated capabilities give the material the ability to detect changes in its environment, change its structural, electromagnetic and/or chemical charact ...

The proposed SBIR program will accelerate the commercialization of multiplexed optical fiber networks and their use in both DoD and commercial systems. F&S (Fiber & Sensor Technologies, Inc.) proposes to implement all-optical low-loss switches for signal multiplexing in large networks. This new approach to multiplexing is based on the development of optically-activated in-line switches to automa ...

The proposed SBIR program would accelerate the commercialization of low-cost miniaturized bioanalysis instrumentation and its use in both DoD and commercial systems. F&S (Fiber and Sensor Technologies, Inc.) proposes to demonstrate the feasibility of integrating mechanically-active polymer microcomposites with evanescent field grating-based optical sensor elements to store, pump and analyze mole ...

This DARPA SBIR Phase I project will demonstrate the feasibility of revolutionary ionic self-assembly methods of creating electric field-tunable thin-film electronic materials and devices. Exciting recent work at F&S and Virginia Tech has shown that the ionic nature of the self-assembly process inherently results in the spontaneous regular geometric ordering of noncentrosymmetric dipole molecules. ...

WE PROPOSE AN ALL-DIELECTRIC FIBER OPTIC TIME DOMAIN SENSOR NETWORK WHICH ALLOWS QUASI-DISTRIBUTED, REAL TIME STRAIN, TEMPERATURE, AND PRESSURE MONITORING. THE SYSTEM PROVIDES FAST DATA RATES, PROVIDES LOW SIGNAL ATTENUATION, OFFERS IMMUNITY TO CORROSION AND ELECTRO-MAGNETIC INTERFERENCE, AND REDUCES NETWORKING COMPLEXITY. THE PROPOSED FIBER ARRAY IS AMENABLE TO SUBMERSED AND/OR BURIED APPLICATION ...

New bellows seal technology to greatly improve seal integrity and life of rising stem and quarter-turn valves in electronic processing, petroleum and chemical processing industries. Bellows seals, considered zero-emission devices by the EPA, are urgently needed to meet current and future more stringent fugitive emissions requirements, but their sensitivity to static pressure and pressure fluctuati ...

The objective of this proposal is to demonstrate the fabrication of ceramic core/composite skin structures using liquid infiltration techniques. The core will be porous alumina rods or tubes and the composite skin will be fabricated via infiltration with alumina sol of an aluminosilicate fabric wrapped around the core. Heating for drying and sintering will be accomplished using both conventional f ...
