The contractor proposes a new approach to underwater imaging that directly converts a two-dimmensional acoustic pressure wave into an electronic requirements fo convential piezo-element arrays. The imager relies on the piezo-birefringent properties of a nematic liquid crystal panel that serves as both sensor and display. The capability of nematic liquid crystals has been established and publishe ...

In this proposal, we describe a novel approach for realizing a parallel, nonmechical, read/write interconnection for angle-multiplexed three-dimensional (3-D) optical memories. Our concept represents a significant first step required toward taking this critical memory technology from the laboratory and inserting it into operational systems. The concept utilizes novel optomechanical packaging and ...

This effort will develop an HLA compliant representation of non-visual stimuli with the intention of utilizing the models developed in Phase I effort to provide data for "human" mannequin stimulation in Phase II. The Phase II goal is to have the mannequin respon in a physiologically realistic manner to the non-visual stimuli data that will be passed to it over a network and via an interface. Suc ...

Federal, state, local, and military missions for Disaster Relief, Emergency Action, and Humanitarian Assistance (DREAHA) require all of the traditional command, control, communications, computer and intelligence (C4I) functions used by military units for traditional warfare. New civilian systems that leverage and reuse military C4I systems to plan, prepare, identify, vector, monitor, and recover ...
