In this project we will adapt our programmable neural network processor (NNP) into a Fuzzy/neural network processor (FNNP). Already having the commercially successful NNP, we begin this program with more than half the work completed. we will define and evaluate NNP architectural modifications to optimize both data flow and data processing for both fuzzy logic and neural network- Operations- we w ...

Monopole and dipole antennas have been determined to radiate most efficiently when the size of the antenna is proportional to the frequency being transitted or received, ie.e, one-quarter, one-half or one wavelength. As the operating frequency is varied from that ideal frequency, nulls begin to develolp which threaten the integrity of the communication link. Experience has shown that small excusio ...

In this proposal, Quadrant Engineering seeks SBIR funds to investigate technologies leading to the development of a compact, low-cost multifunction radar system for use aboard an unmanned aerial vehicle (UAV). If successful, the proposed radar system will provide airborne early warning (AEW), ground mapping and ground motion-detection capabilities. Several novel antenna concepts will be in ...

Computer-based training has primarily focused on the acquisition and application of procedural knowledge, emphasizing development of skilled performance of tasks. In many important Naval roles, however, the ability to apply more general concept to specific novel problems is even more important than procedural skills. Sonar operators, who must reason about acoustic oceanography and sensor/s ...

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; i.e., it is a direct pressure gradient imager. This device can allow a small, battery powered acoustic source to be easily located and ranged using a small flashlight sized ...

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 ...

High pixel count display operation at high frame rates requires high frequency display circuits and a fast light modulation media. Kopin's AMLCD display technology utilizes fast CMOS circuits fabricated in single crystal silicon, which are superior to circuits fabricated in poly-crystaline silicon and amorphous silicon. Display circuits are fabricated on SOI wafers in conventional CMO ...

THE PROBLEMS OF ATTENUATING DUCTED NOISE AND DISTRIBUTED NOISE ARE ADDRESSED USING ACTIVE NOISE CANCELLATION TECHNIQUES. FOR DUCTED NOISE, A COMBINATION OF COMMERCIAL ANC EQUIPMENT WITH LOW PRESSURE DROP MUFFLERS IN AN SVS PROPRIETARY CONFIGURATION WILL BE EXAMINED. COST AND PERFORMANCE TRADES BETWEEN THE ACTIVE CONFIGURATION AND PASSIVE MUFFLERS WILL BE MADE AND AN EXPERIMENT WILL BE DESIGNED FOR ...

The overall objective of the proposed research is to develop bistatic detection techniques for shallow water near land warfare operations. The focus of our proposed research is to achieve detection enhancement in environments characterized by dense multipath through application of optimal detection theory coupled with accurate acoustic modeling. The first specific objective is to consider alternat ...
