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 soot. Potential commercial applications of the real-time sensor include diesel emissions reduction ...

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 filter. Active Spectrum, Inc.’s filters represent a proven, significant improvement over the state ...

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 package, as described in the proposal. The technology is a major step for reducing the SWAP of front- ...

This proposed Phase II program will deliver a lightweight triple-junction solar cell that eliminates the current-matching bottleneck of current state-of-the-art InGaP/GaAs/Ge cells on Ge. This will be achieved by constructing a triple junction structure on the lattice constant of SiGe, allowing the integration of semiconductors with bandgaps that are optimized for the best possible triple-junctio ...

Agricultural row crops occupy over 200 m acres of land in the US. Decisions regarding the implementation of tillage practices in these agricultural areas have a significant effect on other environmental outcomes, including soil erosion, water quality, and carbon sequestration. In addition, the effects of tillage practices can vary due to soil type and topographic conditions. There is currently no ...

This Small Business Innovation Research (SBIR) Phase I project will use Particle Image Velocimetry wherein a sample sheet volume is illuminated by laser diodes. A high speed camera takes pictures of precipitation illuminated in the sample volume. The proposed data analysis software would use object and pattern recognition algorithms combined with statistical analysis packages to generate output da ...

DESCRIPTION (provided by applicant): The objective of this program is to provide a wearable instrument that monitors the level of the robustness of the multilevel control system responsible for human gait and balance stability. Long-term, free roaming gait dynamics measurements, recorded in either the clinic or during the unfettered subject's daily routine, will provide extended-time stride interv ...

Over-the-horizon communications and information networks are beginning to produce sustainable capabilities for Earth science operations using advanced unpiloted vehicles. There is a growing need for affordable desktop access to globally deployable data acquisition and data processing sensor-web networks on board these airborne platforms. Central to meeting this need is further miniaturizing on-b ...

Reserve lithium oxyhalide and silver/zinc batteries are power sources of choice for many missiles and other weapons systems. These batteries achieve long shelf life by storing the liquid electrolyte separately in a reservoir. Upon activation, the electrolyte is injected quickly into the battery cells, most often using a pyrotechnic gas generator. The overall design of the activation system is a ...

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This Small Business Technology Transfer Phase I project addresses the need for greater efficiency and clean emissions in power generation systems. Of particular relevance and potential impact would be the application of fuel cell systems in vehicles. However, the cost of platinum-based fuel cell oxyg ...
