Efforts to apply active noise and vibration control commercially, while intensifying, continue to be hampered by the cost of the computers required to implement the active algorithms. Currently, the cost of wide-band control is prohibitive for lightly damped systems such as precision structures or highly reverberant acoustic spaces, even if the system has just one canceling actuator and one error ...

The Air Force has identified the need to develop affordable flight control technology to support Air Force Global Engagement objectives. Of particular interest to the Air Force is the development of real-time optimization algorithms for cooperative engagement solutions among Uninhabited Air Vehicles (UAV) in a multiple target environment. DSR proposes developing a real-time, rule based, Cooperat ...

As organizations move toward increased performance measurement and accountability, there is an increasing need to measure job performance at the individual worker level. Traditional assessment tools have been criticized as measuring test taking skills more than job performance skills. A number of approaches have been developed to address this weakness by measuring performance in practical proble ...

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 ...

The human brain processes information from several sensors of the body and extracts meaningful information about the environment. Likewise, the ability to fuse multilevel, multifaceted processes dealing with the association, correlation, and combination of data from single or multiple sources is desired to attain state and identity estimates in a timely manner. However, current data fusion techniq ...

Controlling millimeter radio frequency waves with optical signals is a requirement for military communications and radar systems. The advances in the past decade have led to photonic sensors and switches that utilize light beams interacting with RF devices. New capabilities extending to higher frequencies and working over multiple frequency bands are possible using a combination of nonlinear op ...

The Reconfigurable Operator Station Simulator (ROSS) project will provide designers of operator stations for Uninhabited Aerial Vehicles (UAVs) with a rapid prototyping system. In addition, the architecture on which ROSS is based provides a platform on which to build tools that increase the ability of operators to control UAVs and to impart a far greater understanding of the situation to them. T ...

We propose to design and fabricate an optical filter that can be tuned continuously from 1.5 um to 2.5 um with a linewidth less than 1 nm. Our system consists of 2 separate filters that can each be electronically tuned. One provides a large free spectral range, and the other provides a narrow linewidth.

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 ...

The opportunity addressed in this proposal is a fast-acting cryogenic injection valve for pulse detonation rocket engines (PDREs), which are predicted to significantly out-perform current state-of-the-art chemical deflagrative rocket propulsion systems. The developed valve would allow high mass flow rates to be achieved with fast response times, all at minimum cost, weight, power, and volume. Th ...
