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- ...

Piezoelectric ceramics in sensors have achieved substantial market penetration. These parts are used widely for heat and climate control, hydrophones, flow sensors, medical and industrial sensing and accelerometers but they have been unsuccessful in gaining significant use in actuators. It generally is felt that material restrictions, precluding development of actuator-sized displacement strokes ...

Currently, wireless sensors have been used in variety of applications such as surveillance, real-time data sharing, in-vivo medical devices, condition-based monitoring, etc. that can revolutionize industrial efficiency, health monitoring, and data processing. MEMS technology made possible autonomous wireless sensor nodes via the use of widespread, tiny sensors in large numbers. However, the shee ...

Advanced Cerametrics, Inc (ACI) has developed a new ceramic material to compete directly with the very high priced reaction bonded silicon nitride (RBSN) and obsolete Pyroceram radomes. ACI has built on earlier work done by NAVSEA to develop a repeatable and inexpensive process to produce radomes from Barium Alumino Silicate (BAS) using high temperature eutectic BAS fiber as a reinforcement for th ...

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 ...

DESCRIPTION (provided by applicant): Breast cancer is the second most common type of cancer in females, causing over 40,000 deaths in the United States annually. Recently, cancer vaccines have arisen as a potential therapy and several target antigens have been identified in Breast cancer, including Her2/neu antigen. The goal of cancer vaccines is to generate effector T cells that are able to infil ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...
