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 ...

Secure broadcasting mechanisms play an important role in satellite-based communications networks. In this Phase I SBIR project, Artery Communication Technology Inc. proposes a scalable secure data broadcasting architecture that is both bandwidth efficient and as secure as state of the art public key cryptosystems. The major emphasis of this project is to analyze the detailed performance behavior ...

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 ...

DOD's plan to make all U.S. military equipment run on a single fuel, logistics fuel, has obvious logistics advantages, but will require replacement of spark ignition engines with diesel engines or gas turbines. Both diesel engines and gas turbines are systems which must be operated fuel lean. Consequently, the three way catalyst system used in automobiles can not be used to control their emissio ...

A novel low-temperature technology for treatment of dilute gaseous effluents contaminated with volatile organic compounds (VOCs) and other hazardous air pollutants (HAPs) is needed. Existing and emerging technologies are based on various combinations of thermal, photothermal and catalytic processes in oxidative or reductive environments. They suffer from emission of toxic substances, employment o ...

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 ...

To field characterize laser systems the laser power, beam divergence, intensity profile and spot size of the laser must be measured with a robust, vibration insensitive system. While some of these parameters can be obtained using conventional components, beam divergence is difficult to measure because of the complexity and vibration sensitivity of typical interferometry based elements. We propos ...

We propose to develop a novel high speed, frequency controlled, single mode semiconductor laser based on planar ring resonator geometry. The technique utilizes electromagnetic fields interference effects within a coupled circular cavity to selectively shape the spectrum and determine the operating frequency of the laser. Unlike its counterpart distributed feedback (DFB) the ring resonator laser ha ...

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 ...
