Applied Physical Sciences and the Navmar Applied Sciences propose to adapt existing vector sensor and sonobuoy technology within their respective areas of expertise to develop a preliminary design for a passive deep water directional sonobuoy. The Phase I Base is centered on tasks pertaining to vector sensor design with emphasis on achieving the stringent noise floor criteria in an A-Size sonobuoy ...

Through this effort, NanoTechLabs Inc. will improve the efficiency and lower the mass of the cryogenic heat exchanger used in American Superconductor's High Temperature Superconducting Degaussing system. NanoTechLabs will achieve these goals by producing a Carbon Nanotube metal matrix composite. Carbon Nanotubes have a room temperature thermal conductivity of ~3000 W/m K and a density of ~1.3 ...

In a Phase I effort, Corvid Technologies will develop and test candidates for a series of advanced ballistic shields for crew served weapons stations intended to replace heavy, cumbersome shielding that does not meet required specifications. Current armor production efforts by Corvid will be leveraged, which share similar ballistic and environmental requirements. Corvid also offers a unique approa ...

One of the main obstacles to the useful exploitation of dimensionality reduction, both linear and nonlinear, is the lack of effective synthesis methods to generate examples in the original exploitation space, as opposed to the low dimensional parameter space. The ability to interactively navigate in the appropriate relevant low dimensional representation, and simultaneously observe the related"ori ...

Signal Innovations Group proposes a hierarchical Bayesian approach for non-linear dimensionality reduction that addresses three key challenges: learning a reversible mapping from a high-dimensional observed space to a low-dimensional embedded space, learning the dimension of the embedded space, and generating new high-dimensional data for a given location in the embedded space. The proposed genera ...

Applied Physical Sciences (APS) has developed a plan to improve the design and development of submarine towed array vector sensors that employ single crystal accelerometers so that they meet Navy specifications, but do so at significantly lower cost relative to earlier variants. Tasks in the Phase I study include developing a comprehensive cost-model which will ascertain the feasibility of various ...

We propose the design and development of a novel gyroid transducer comprised of piezocrystal ring elements. The Phase I effort covers the modeling and demonstration of the gyroid transducer and comparison of performance with several piezocrystal and piezoceramic materials. The electroacoustic performance will be estimated for several designs and a prototype element will be built and laboratory tes ...

On today"s battlefields, vehicles are at risk of encountering improvised explosive devices (IEDs). Fortunately, not all of these result in complete vehicle loss. Sending a vehicle back to the depot for overhaul when it could have stayed in operation, wastes precious resources. Conversely, leaving a damaged vehicle in operation without some level of confidence that it can withstand a second blast p ...

The US Navy, Naval Surface Warfare Center (NSWC) plans to upgrade its facilities at the Acoustic Research Detachment (ARD). Part of this upgrade includes installation of volumetric measurement arrays to characterize the radiated acoustic signatures of scale submarine models. At low and mid-frequencies the planned volumetric arrays will likely resemble those currently installed at the Southeast Ala ...

We propose to develop a collaborative control user interface that will enable operators to work more effectively with highly autonomous vehicles by engaging in a dialog to exchange ideas, ask questions, and resolve differences. We will develop a concept of operations for the collaborative control user interface, and we will create specific, representative scenarios describing situations and events ...
