The proposed approach for Phase I of this effort brings together two key items that are needed to work in concert with one another: advanced fatigue assessment methods and non-destructive inspection & detection techniques. Successful synthesis of these elements and the engineering disciplines behind them will provide an optimized and advanced method of taking full advantage of engineered residual ...

The USAF recognizes that benefits to cold working fastener holes include significantly increased life of a structure subjected to fatigue loading. However, full realization of this potential from a maintenance and engineering standpoint is hindered by the fact that there is currently no adequate field technique for determining how well the material structure immediately surrounding the hole has re ...

The Phase I objective is a conceptual design of a hyperspectral/multimodal fundus camera for assessing laser damage.  The premise to be ultimately proven in this project is that damage to the fundus, from laser irradiation, may be characterized and detected by reflectance spectra, and by measuring function such as flow and perfusion.  The system will incorporate an existing fundus camera model ( ...

Digital and hardware-in-the loop simulations have become essential to the development of modern sensors and weapon systems. The use of these simulations speeds development, offsets field test costs and provides the opportunity to assess system performance for operational conditions that cannot be practically tested any other way. The evaluation of signal/image processing algorithms along with s ...

The objective of our proposed effort is to demonstrate the feasibility of an extremely rapid analysis of whole blood samples in non-laboratory environments using MEMS-based fabrication techniques combined with new developments in highly specific antibodies. We believe this technology will enable the realization of a small handheld portable blood analysis system with a quick response time, which w ...

The overall goal of this project is to develop a flexible acuity sensor (FAS), including both hardware and software, and demonstrate its ability to acquire and track moving targets in the environment, including when the sensor itself is moving. These sensors will utilize a proprietary Centeye vision chip capable of acquiring images at multiple resolutions and frame rates. The sensors developed wil ...

Cermet proposes to demonstrate MgZnCdO based light emitting diodes on native substrates. This will be accomplished by focusing on three technical areas. First, Cermet will increase its existing p-type ZnO capability to greater than 1e18 holes per cm^3. Second, Cermet will refine alloy growth across the quaternary system to address a wide emission wavelength range. Finally, Cermet will develop ...

This phase I development will provide a low defect InGaN p-n junction tuned to 2.6 eV. The characteristics of the junction will be high electron and hole concentrations, low defect density and no phase separation in the InGaN. This will be accomplished using a revolutionary epitaxial technique, combined with lattice-matched substrates and state of the art device fabrication.

The adoption of Web 2.0 tools and technologies has enabled new information sharing workflows that are mandated by a need-to-share in government and commercial environments. These workflows introduce new sources of potential information leaks, while the need for securing sensitive information remains critical as ever. Emerging net-centric tools, together with advanced automated cognitive techniques ...

This project will develop a field portable nondestructive technique for in-situ monitoring of the health of ceramic armor. The Evisive Scan microwave interference scanning method has been successfully demonstrated in Phase I of the project, where it was demonstrated successfully on Control Specimens and ceramic armor Surrogates designed and fabricated by ARL, and on samples of armor from Stryker ...
