The proposed project will undertake the research, design, and development of key concepts and technologies for a high-speed electronically tunable channel filter, based on monolithically integrated ultra-high-resolution super-compact grating (UHR-SCG) technology that has been developed in OptoNet. The grating will be realized on Silicon-Photonic Electronic-Photonic Integrated (EPIC) Platform that ...

The objective os this work is to utilize acoustic emission for early detection of cracks in helicopter gearboxes. Cracks will be identified including their location and extent, the system is envisioned to communicate this information as well as the remaining life of the part. Statistical signal processing and conditioning will be a vital part of the work. AbM Engineering, LLC is partnering with Em ...

Our team proposes a unique expendable acoustic source comprised of flexural disc technology in a close packed arrangement that allows for a reduction in resonant frequency and an increase in useful bandwidth. This array will be designed to couple as much energy as possible into the bottom sediments, while coupling as little energy as possible directly into the surrounding water column. This is a d ...

A notable failure mechanism in thermal barrier coatings (TBCs) is the attack by calcium-magnesium-alumino silicate (CMAS) deposits resulting from the ingestion of siliceous minerals with the intake of air. Existing TBC systems such as yittria partially stabilized zirconia (YSZ) are highly susceptible to CMAS infiltration. In this STTR program, QuesTek Innovations LLC, a leader in the field of comp ...

High quality laser materials based on InP, InGaAs, InAlGaAs, and InAs are proposed to develope high power 3 to 3.5 m diode lasers. An adiabatically broadened amplifying section is proposed to reach high power with high beam quality. The active material uses strained layer epitaxy to rely only on high quality laser materials that can be grown by molecular beam epitaxy, and with high quality on InP ...

Capacitive energy storage is a critical technology for advanced electronics as well as a necessary technology for the implementation of intermittent, renewable power generation. Innovative and scalable nanofabrication techniques are required to enhance the performance and energy density of capacitors as well as many other energy storage and conversion technologies. Mainstream"s nanostructure array ...

Current otoacostic emission probes used diagnostic evaluation middle and inner ear components of hearing are not capable of producing well-calibrated and high-quality acoustic stimuli that cover the entire frequency range of human hearing and are thus unsuited for rapid evaluation of the range of inner ear damage from ototoxic drugs, noise and the normal process of aging. The accuracy of stimulus ...

The XS-Air engine should provide the highest power density with both diesel and gasoline piston engines. This would be especially true in smaller engines in where turbos or blowers are impractical. The XS-Air engine can solve the aviation industry problem of the potential phasing out Av-gas. The spark ignition XS-Air engine should be able to burn pump gas and still generate extreme power densities ...

This Phase I Small Business Innovation Research Project develops methods of recycling rare earth alloys from used nickel metal hydride batteries. Alloys of rare earth metal, nickel and other metals provide functional hydride storage materials that are critical to the operation of nickel metal hydride batteries and their applications. The current fleet of hybrid electric vehicles relies upon nick ...

This EPA SBIR Phase I proposal addresses the need for more widespread electricity usage conservation and user cost reduction via behavioral changes and via efficiency improvement. Efficiency improvements are through equipment and appliance change out but also via long term efficiency monitoring. This needs to be a sustaining level of conservation and efficiency verification as opposed to a one t ...
