As we progress towards the network-centric environment envisioned by JV2010 and JV2020, our dependency upon space assets to meet our force enhancement (C4, weather, navigation, intelligence, surveillance, etc.) requirements is expected to growexponentially. This trend is not only for our forces, but the forces of our potential adversaries, as well. With so many mission critical assets parked in v ...

70042S02-II The quantification of sources and sinks of atmospheric carbon dioxide would be greatly facilitated by the development of a new detector for this important greenhouse gas. In particular a lightweight CO2 sonde, similar to the widely used ozonesonde, could be used to estimate landscape-scale (approximately 100 km2) fluxes of CO2 from vertical profiles through the convective boundary ...

Balloon-borne radiosondes are used extensively to collect meteorological data in atmospheric research programs funded by NOAA, WMO, DOD, DOE and others. The launch of radiosondes requires skilled personnel at each launch site to perform tasks such as balloon filling, sonde pre-conditioning and attachment, and physical release of the equipment. At present no low-cost, simple, lightweight, and rob ...

70474B02-II Phytoremediation is a largely experimental technique to remove excessive amounts of metals from contaminated soils. However, currently available measurement and analysis techniques are slow and expensive, thus impeding metals remediation using this desirable approach. Technology is needed for the immediate and inexpensive assessment of metals accumulation in plants during phytoext ...

NON-TECHNICAL SUMMARY: Certain fruits do not change color as they ripen and hence it may be difficult for consumers to select fruit that is ready to eat. Melons and winter pears are examples of fruit that is difficult to select. Most fruit is now individually labeled and this project will develop a label that will change color as the fruit approaches ripeness. This colorimetric label will provide ...

The use of finite element analysis (FEA) modeling techniques to model both single hearing protection and double hearing protection noise attenuation will be refined during this Phase II program. Physically realistic, three-dimensional models ofcircumaural earcups and custom PVC earplugs will be created using the ABAQUS FEA software and coupled to fluid models of the ear canal geometries for a var ...

The Phase I research effort delivered a fully functional wired binaural microphone prototype capable of providing realistic hearing capabilities to a remotely located soldier. Building on the successful completion of Phase I, the Phase II developmenteffort will refine the current design, add enhanced hearing features, and deliver two wireless binaural microphone systems to the Army. The Phase II ...

The advent of MEMS (micro electro-mechanical systems) was supposed to cause a market revolution with its breakthrough in miniaturization. In practice, this potential has not been realized chiefly due to the power limitations to which MEMS are subject. Onlyrelatively simple applications, e.g. in pressure sensing and optics, have been commercially developed. With the laser engine described in this P ...

The objective of the Phase II research is to utilize the lessons learned from the Phase I risk reduction work to develop a prototype CAD-programmable environment for the development of condition-based maintenance systems for rotorcraft. This developmentenvironment features a CAD scenario modeler for constructing, via click n' drag modeling, fault-to-failure damage models which can account for the ...

On-orbit servicing and logistics support spacecraft could greatly enhance the flexibility and functionality of many future MDA space assets by providing, refueling, diagnostic, or component replacement services. AeroAstro proposes to take the first stepstowards achieving an affordable on-orbit servicing and logistics capability by developing a scaleable, modular spacecraft architecture and applyi ...
