Most standard-of-care tools and techniques for evaluating neck disorders are subjective, unreliable, and do not provide actionable information for providers, payers, and organizations to deliver efficient and effective care. This lack of objective neck he

White River Technologies, Inc. proposes this effort involving non-acoustic sensing methods and sensor fusion technologies to detect and characterize seabed objects of interest in littoral environments relevant to US Naval activities. Current and evolving threats to maritime dominance require the Navy to adapt to potential hazards from a variety of sources, which could include terrorism, and to ope ...

The objective of the Phase I proposal is to investigate the application of controlled cavitation cleaning technology in conjunction with gecko-inspired mechanical adhesion and soft elastomeric applicators for use in non-intrusive EOD operations. This investigation requires the proof-of-concept testing and validation of a controlled cavitation cleaning mechanism, and a soft robotic gecko-inspired m ...

Waste heat from Naval diesel generators provides significant opportunity to introduce organic Rankine cycles (ORC) to increase their fuel efficiency. The objective of the proposed effort is to design and demonstrate a high-speed, spinning scroll expander (HiSSSE) ORC as a power dense waste heat recovery system for diesel generators on ships. The system will leverage Air Squared’s spinning scroll ...

The STTR topic N19A-T013 seeks innovative technology to improve the power density and efficiency of propulsion and power generation devices. To address this challenge, Spectral Energies in collaboration with its academic partner Dr. Rory Roberts at Wright State University proposes to develop a compact heat recovery system based on a supercritical CO2 based Rankin Cycle. At the end of the STTR prog ...

Accurate characterization of and propagation modeling through the Marine Boundary Layer is critical for maximizing Electro-Magnetic (EM) systems signal exploitation for naval asset offensive, defensive, and stealth operational performance. Strong temperature and humidity gradients in the Surface Boundary Layer lead to optical paths exhibiting Electro-Optic Infrared (EOIR) anomalous refraction and ...

Texas Research Institute Austin, Inc. (TRI/Austin) and Florida Institute of Technology (FIT) in the Phase I effort will implement the use of a revolutionary new class of adhesives to attach C4 to underwater mines. These adhesives are extraordinarily insensitive to water, tolerant of unprepared surfaces, and offer extremely rapid cure and excellent bond strength. These materials can be applied usin ...

The U.S. Navy seeks methods to improve the fuel economy of marine diesel engines through utilization of waste heat. Low temperature engine jacket water, lubrication oil, and aftercooler air are largely untapped streams of thermal energy on these ships, but their utilization circumvents many operation challenges associated with exhaust gases. For example, variable and high exhaust gas temperatures ...

Vertically-aligned carbon nanotubes (VACNTs) will be selectively applied at interfaces in laminated composite structures to effect locally the mechanical properties that limit rotorcraft structures, such as fatigue and damage tolerance. In Phase I this work will quantify these effects in CFRP and CFRP/GFRP hybrid coupons. The VACNT material will be transferred directly onto prepreg plies, but also ...

Composites are often used in aerospace applications due to their superior specific strength and stiffness properties, as well as their resistance to fatigue and corrosion. In particular for rotorcraft, composites offer additional benefits for their versatility in tailoring material properties for such components as rotor blades. However, rotors introduce additional challenges by including multiple ...
