AbTech Corporation proposes to apply its unique Statistical Network ModelingTM technology to develop a non contact prognostic assessment tool that 1) acquires, processes, and analyzes electronic radiated signal data, 2) learns the expected characteristics and patterns of specific radiated signals measured from microelectronic semiconductor devices using AbTech's statistical network modeling techno ...

One of the biggest problems faced by both military and non-military personnel in planning and conducting Operations Other Than War (OOTW) and Law Enforcement (LE) is a lack of cultural awareness. A lack of cultural awareness in OOTW causes misplanning and misinterpretation in the areas of economics, politics, religion, and historical events. The objective of the proposed work is to produce a des ...

The contractor has patented technology for a unique process that directly converts a two-dimensional acoustic disturbance, such as a wave front, into an intensity-mapped visible image in real-time without electronic circuitry; that is, it is a direct pressure gradient imager. The imager relies on the piezo-dichroic properties of a continuous layer of a dichroic material thin film that serves as bo ...

DDL OMNI Engineering proposes to design a secure system for the continuous, real time acoustic measurement of towed array position relative to the host submarine. By using focused transmit and receive assemblies, pseudo- random spread broadband signals, and relatively high carrier frequency, the transmission level will be minimized so as to be virtually undetectable by a non-dedicated system ...

Composite materials find increasing importance as structural materials for modern lightweight and low cost aircraft. Structures using composite materials essentially rely on the integrity of adhesive bonds for their structural stability. A major limitation in employing composites in critical structures is that the existing methods of testing the integrity of structures are not adequate to a ...

Active noise reduction (ANR) headsets have found a market niche in the hearing protection industry, thereby validating the technology of active noise control for personal applications. This Phase I project will seek to extend the application of personal ANR systems to include specialized headphones which can successfully evaluate hearing acuity in typical clinical environments. To ensure a succe ...

SEEKER STABILIZATION VIBRATION SUPPRESSION ELECTRO-ACTIVE MATERIALS PROPULSION RESEARCH WILL USE ITS MINIATURE "FERRO-MAGNETIC" ACTUATOR EFFORTD CAN BE USED TO CREATE A "SEEKER ANTI-MOTION SYSTEM". THIS TECHNOLOGY TAKES AN AGGRESSIVE APPROACH TOWARD "INTELLIGENTLY" MANAGING THE SEEKER DYNAMIC RESPONSE TO INDUCED MOTION BY ISOLATING IT "DYNAMICALLY" FROM THE REAMINDER OF THE AIRFRAME USING ELECTRO- ...

Control systems that stabilize the operation of a compressor around the surge line have been demonstrated in controlled laboratory conditions on fixed speed compressors. Jet engine manufacturers are considering this technology for improving engine performance and operability by reducing the compressor surge margins that are currently built into engine control logic. To demonstrate this technolog ...

This project proposes preliminary investigations to prove the feasibility of four techniques for improving Adaptive Beamforming performance in littoral environments. Emphasis is placed on tradeoffs between algorithm efficiency and performance. The littoral acoustic environment is characterized by near and far field targets and dense dynamic near and far field directional interference at man ...
