Advanced Photonics Technology (APT) proposes to develop novel, wide-band, highly linear integrated-optical modulators based on low-loss waveguides in ferroelectric (e.g., lithium niobate and lithium tantalate) crystals with domain-inverted sections. The application of domain inversion to electro-optical modulators introduces a novel approach that allows the development of devices with low levels o ...

It is difficult to remove oil and AFFF from voluminous streams. Research has been continously carried out to develop new technologies to be employed in this field of application with little success. Air-sparged hydrocyclone (ASH) flotation technology is a new technology developed by the University of Utah and Advanced Processing Technologies, Inc. It combines the advantages from both conventional ...

The United States Army has identified the need for high power efficiency transmitter systems. The goals of the U.S. Army can be achieved through the use of switched mode amplifiers used as Class D or E. The objective of this proposed Phase I SBIR program is to design a pair of complementary FET's (N-Channel and P-Channel) capable of switching at frequencies sufficient to provide switch mode ampl ...

We propose a radically innovative approach to the problem of multiple access communication which promises to revolutionize the modern communication industry by dramatically increasing network throughput. Our approach is based upon two major novel components: (i) hybrid time-frequency allication of communication channel resources, and(ii) non-orthogonal, i.e., overlaping, multiplexed signals. Toge ...

This effort will integrate an advanced technology speech recognition system (SRS) with a computer-assisted contingency planning training model. The SRS makes use of algorithms developed in the Speech Technology and Research Labratory of SRI International. Its state-of-the-art approach provides significant improvements in accuracy and robustness over other approaches. It provides for speaker ind ...

An operational requirement is projected for an inexpensive, mobile, submarine acoustic countermeasure capability. A significant tactical advantage is gained by putting as much distance as possible between the submarine (launch platform) and the mobile countermeasure. An additional advantage is gained if the submarine has the ability to place the ADC between itself and the torpedo threat. Adding ...
