While in the 1970's and 1980's, composites were adopted for aerospace structure for increased performance and weight savings, the 1990's and 2000's witnessed the attention towards cost-effective fabrication. All thermoset processes that utilize such machines rely on autoclaves to consolidate the laminates, at significant acquisition and operational expense. Autoclaves to consolidate wings are hu ...

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- ...

The environmental impacts of coal bed methane development (CBM) in Montana and the Rocky Mountain States are well documented. CBM exploration is expanding rapidly with the nation's focus on energy independence and the relative ease of extraction. Extraction of CBM necessitates pumping large volumes of often saline discharge waters to the surface. The impacts of those waters include: reductions in ...

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 ...

In this NASA Phase I STTR effort, the feasibility of fabricating isolated ridge waveguides in 5% magnesium-doped lithium niobate (5% MgO:LN) will be established. Ridge waveguides in MgO:LN will significantly improve the power handling and conversion efficiency, increase photonic component integration, and be well suited to space based applications. The key innovation in this effort is to combine ...

This SBIR Phase I effort will establish the feasibility of fabricating advanced waveguide structures in potassium titanyl phosphate (KTP) capable of efficiently generating 25 to 40 mW of frequency converted light in the 395 to 480 nm. The key innovation in this effort is to utilize KTP waveguides in a single-pass frequency doubling device to efficiently produce the desired laser wavelengths and po ...

This SBIR Phase I effort proposes to establish the feasibility of developing a compact, high performance laser source for integration into the next generation seed laser system for high stability, multi-wavelength lidar applications such as NASA Langley's HSRL program. Combination of the high performance laser source together with ADVR's integrated Planar Lightwave Circuit (PLC) technology will p ...

This Small Business Innovation Research Phase I project will develop a compact, rugged, rapidly and widely tunable laser based on a quantum cascade diode laser at mid-infrared wavelengths. The key innovation in this effort is the use of an engineered electro-optic tuning element in an external cavity laser to provide control of the laser wavelength through an applied voltage. AdvR has previously ...
