This project is the development of a single crystal underwater acoustic modem transducer for Unmanned Underwater Vehicles (UUV) which is compact in size, operates at low to moderately low center frequencies, in a broad band frequency range to accommodate state-of-the-art binary, FSK and spread spectrum signaling schemes that promote covertness. The device exploits the high coupling coefficient an ...

We propose to research, develop, and validate an innovative Toolkit for Agent-based Knowledge Extraction (TAKE). The proposed research uses (a) a hybrid approach that combines ontology engineering methods with emerging knowledge discovery techniques to extract, analyze, and map ontologies from distributed and disparate knowledge and data sources and (b) deploys the ontology mapping results for th ...

Wet install” rivets/fasteners use two-part sealants that are hand brushed onto the sleeve just prior to installation – associated labor and schedule costs are significant, and quality variation can be high. Rivets with a pre-applied sealant are an obvious but technically challenging solution. To get cure-in-place seals on rivets/fasteners means blocking sealant cure until installation. Cure ...

The MK48 Advanced Capability (ADCAP) Heavyweight Torpedo is a primary submarine weapon and is considered the workhorse of the fleet. Flex hose assemblies are a major connectivity component that provides 100% accurate data exchange between the recently fired torpedo and the submarine, and are a key component in ensuring fleet combat readiness. Current Flex Hoses use toxic metallic lead for ballast, ...

The Marine Corps has indicated a need for a new technology that could form the basis of non-lethal and non-destructive weapons. The purpose of these weapons would be to render an adversary either incapable or unwilling to resist installation of captive restraints. This incapacitation must last for a period of time needed to subdue the individual and by means of restraint installation preclude an ...

Universal Modular Masts (UMM) are non-hull penetrating masts designed for advanced submarine systems. The UMM was developed for the Virginia Class Submarines, and is in production for both the Virginia and SSGN. The UMM approach is to have a common, universal mast design which can support all the sensors and antennas housed in the sail for above-water use at periscope depth. The current UMM made ...

Presently, infrastructure for the transportation and storage of packaged fuels remains the limiting factor to the widespread use of portable fuel cells. Significant effort is currently underway to test and regulate several packaged fuel options, including concentrated and dilute methanol packages, metal hydride based hydrogen storage systems, and logistics fuels. Although several early portable f ...

21 st Century Technologies Inc proposes the Integrated Fusion Dashboard, a level 2-3 knowledge-based asymmetric pattern recognition, detection, and fusion framework supporting persistent and adaptive surveillance collection strategies. We shall exploit specialized detectors, learning and reasoning algorithms, and social network analysis that access integrated Multi-INT data and synergistically ...

Nanohmics is developing a light emitting diode (LED) based strobe light system that emits intense light at 365 (lens fluorescence) or 520 to 550 nm light (eye sensitive) wavelengths to distract or disorient potential adversaries. This device is being developed as an alternative to a Stun Grenade for use in situations where pyrotechnic devices must be avoided. This capability will reduce the prob ...

Underwater acoustic modeling plays an essential role in the design, development, test, and operation of sonar systems. Active acoustic clutter can increase the sonar false alert rate or equivalently decrease the probability of detection/classification, and is a key issue in the development and utility of active sonar systems. The ability to predict reverberation and clutter is inseparably tied to ...
