We propose a novel, high performance tunable narrowband bandpass preselect filter that is capable of continuously tuning from 400MHz - 3GHz. The proposed filter offers an order of magnitude reduction in SWAP-C, small size (1/2" x 1/2" x 1/4"), low cost and minimal power consumption. The proposed… More

Precise monitoring and maintenance of engine lubricating oils is essential to extend operating life and minimize engine wear. Oil analysis has long been used by the Navy for preventative maintenance of its fleet. However, the manpower requirements for these maintenance programs place a significant… More

DESCRIPTION (provided by applicant): Electron spin resonance spectrometry is a widely used technique for the detection of free radicals and paramagnetic centers. There are over 23,000 published biomedical research papers citing this technique, particularly the use of spin labeling and measurement… More

Active Spectrum, Inc. proposes a novel, low-cost soot sensor for on-board measurement of soot emissions in diesel exhaust gases. The proposed technology is differentiated from existing method by excellent sensitivity, high specificity to carbon particulates, and robustness to fouling by accumulated… More

The objective of this proposal is to demonstrate the feasibility of mass producing robust miniaturized, tunable narrowband preselect filters in the 500-2000 MHz bands for fielded JTRS platforms. In the 500 MHz - 2000 MHz frequency bands, we proposed a tunable 2-pole narrowband (30 MHz) preselect… More

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This Small Business Innovation Research Phase I research project will test the feasibility of increasing diesel fuel economy while reducing soot to below EPA emissions standards for diesel exhaust by… More

The proposal describes a miniaturized tunable filter technology for wideband tuning in the 500 MHz to 3 GHz bands. The filters use a novel actuator to achieve a combination of wide tuning range and high-Q of the resonant elements. The filter technology can be integrated into a small surface mount… More

We propose development and field testing of a high frequency, miniaturized electron spin resonance spectrometer (X-band Micro-ESR) to measure degradation of marine lubricants, gear oils and hydraulic oils in real time. Lubricants and other fluids of interest will flow continuously through the sensor… More

This Small Business Innovation Research (SBIR) Phase I project involves field analysis of crude oil emulsions using electron spin resonance (ESR/EPR) spectroscopy. The recent BP oil spill in the Gulf of Mexico is substantially different from previous oil spills in that a large fraction of the oil… More

This Small Business Innovation Research Phase II project will result in the development of a miniature airborne soot sensor for automotive diesel engine exhaust sensing applications. Current government regulations mandate that by 2012, all diesel vehicles sold in the United States will be equipped… More

We propose to develop miniaturize, high performance bandstop filters demonstrating low insertion loss in the 1-20 GHz range, broad tuning, and high RF power handling capability for interference mitigation in shipboard radar and communications systems.
