The removal of noise from complicated signals and images is a fundamentally important problem. Traditional methods, based on classical adaptive communication theory, have limited ability when presented with complex signals and images. Wavelets have recently been proposed as a potentially useful de-noising technology. Athena proposes QUIESCENT, a comprehensive wavelet-based de-noising study leadi ...

The potential to reduce US Army tactical generator set weights and sizes will be explored through the combined application of High Frequency Alternators and Power Frequency Converters. The application of such technology will improve the mobility and deployability of the tactical equipment as performance requirements become more demanding. High speed alternators can be decreased in size proportio ...

The U.S. Army has identified a need to accurately engage ground targets with low-cost munitions delivered from self-propelled artillery and towed guns. Currently, munitions delivered from these platforms are not equipped with navigation sensors, and thus have no way to measure position, velocity, or attitude during flight. Without this information, munition accuracy is entirely reliant on launch ...

DBA SYSTEMS, INC. PROPOSES TO FABRICATE AN ENGINEERING MODEL OF A PC-BASED VIDEO MENSURATION SYSTEM FOR THE DETAILED HUMAN FACTORS ANALYSIS ASSOCIATED WITH MOTOR VEHICLE OPERATION. THE BASELINE FOR THIS SYSTEM WILL BE DBA'S OFF-THE-SHELF 626 VIDEO TRACKER THAT TRACKS VIDEO IMAGES AT REAL-TIME RATES (60 HZ). ENHANCEMENBTS WILL INCLUDE THE DEVELOPMENT OF REAL-TIME FITTING AND LATERAL POSITIONING ALG ...

An azimuth orienting system is proposed for indirect fire towed artillery and mortar weapon systems based on an enhancement of existing fiber optic gyroscope (FOG) technology configured into a north finder system. The north finder in operation would use its FOG rate sensor(s) to determine the Earth's rotation vector in a local horizontal plane. The direction of the vector in this plane points to t ...

A microcomputer controlled (Digital) gun sight is proposed that would eliminate most if not all of the manual operations needed by the current generation of mechanical/optical howitzer sights. This sight would also include a north finder and azimuth orientation sensor which would remove the need for surveying in the gun's reference direction and would maintain the reference direction during firin ...

Proton exchange membrane (PEM) fuel cells provide significant advantages over conventional power systems. They operate at very high efficiencies (greater than 50% direct conversion and at system efficiencies which can exceed 40%), generate no emissions, are responsive to rapid start up and load changes, and operate near ambient temperature and pressure. Units have been developed for and applied ...

A portable non-invasive technology for monitoring surface and deep tissue oxygenation will be identified and proven during Phase I of this project. During Phase II this technology will be demonstrated and production-prototyped as a system. The device, as envisioned, will facilitate in-field monitoring of personnel under physiologic stress caused by activity, environmental conditions and direct t ...

This project will identify, develop, and demonstrate optics optimized for head mounted displays. All potential approaches will be explored, but special attention will be given to a holographic optical concept developed at the University of Central Florida (UCF). This holographic approach promises to provide the combination of compact size, high performance, affordability, light-weigth, and manufac ...
