Not Available A new approach to significantly increasing the level of monolithic integration of InP based photonic integrated circuits for RF applications is the subject of this proposed Phase I program. The method is based on a vertically coupled twin wave guide design that has already been successfully used to fabricate lasers and amplifiers. The fabrication process requires no epitaxial re-g ...

Not Available In the course of developing the solar powered Pathfinder and Centurion high altitude long endurance (HALE) uninhabited air vehicles (UAVs), AeroVironment has done extensive investigations into the effects of atmospheric turbulence on this unusual class of aircraft. This investigation found that turbulent loads are the driving factor in the design of these vehicles. In particular, ...

The Defense Modeling and Simulation Office (DMSO) has developed the High Level Architecture (HLA) as one of the principle components of a DoD-wide Common Technical Framework for modeling and simulation (M&S). Unlike previous distributed simulation technologies such as DIS and SIMNET, HLA provides federation developers, via the Object Model Template (OMT), the means to define the structure and for ...

The Joint Venture of Damona Service Company and the Fastenix Corporation proposes to develop self-locking fasteners for airframe assembly and repair. The design concepts for these self-locking fasteners are well thought-out. A prototype fastener is made and proves the design concept works. In order to claim total success of the product, mathematics and stress models need to be developed to pred ...

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 ...

The objective of the proposed program is to address the high service costs of the current U.S. Navy fleet of aircraft by developing a distributed optical fiber sensor system that will help reduce the costs associated with corrosion damage and extend the lifetime of existing aircraft. Annual corrosion of Navy metallic structures has been estimated as high as $1 billion. Additional costs aris ...

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 proposal focuses on the development of heterostructure acoustic charge transport (HACT) Spatial Light Modulator (SLM) structures, which potentially address a larger number of pixels with substantially fewer interconnects, as input and output devices for a 3-D volume optical memory. Unlike other types of SLMs, HACT addressing of a 10(6) pixel array requires only 3x1024 interconnects in place ...

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 ...
