Summary
Description
Energid Technologies will create a comprehensive software infrastructure for rapid validation of robotic designs. The software will support push-button validation through existing commercial design software, such as SolidWorks. After validation is invoked through the design-tool GUI, the robot design will transfer to separate networked software for analysis. An interface will be provided for communicating with many types of commercial analysis software, and Energid will provide its own analysis software through the common interface. This will allow interactive placement of any number of end effectors on any number of mobile or fixed-base mechanisms, each with any number of kinematic links and branches. Energid's validation software will provide dynamic simulation, including articulated-body and impact dynamics. The software will allow link descriptions, end-effector descriptions, control algorithms, and the environment to be arbitrarily exchangeable as modules. The Extensible Markup Language (XML) will be used for configuration, data transfer, and exchange.

CISO is implementing an automated solution that will provide actionable reports to the owners of USAIDfunded websites. The solution will automate creation and distribution of reports, reducing CISO staff demands and mitigating human error that can result from a manual reporting process. This solution mitigates the risk of secuity compromises on USAID-funded websites.

Summary
Description
Utilizing centrifugal force as the primary body-force, combined with both shearing flow and vibratory motion the proposed centrifugal-sieve separators can provide efficient gravity-level-independent size classification of granular feedstock like lunar regolith. Standard size separation methods for dry materials often depend on gravity as the primary body force. For separation of small sizes, gravity-force is usually supplemented with vibration and shearing flow. Granular materials naturally stratify during shear-flow with larger particles rising to the top. Depending on frequency and intensity, vibrations alone can induce large particles to rise to the top in a granular bed, independent of shear flow. The proposed centrifugal size-separators utilize the natural size stratification of flowing granular solids. They will function equally well under reduced gravity conditions and in vacuum. The nominal design is a configuration with only one moving part and no blades, or other high-wear components. Shearing flow and vibrations combined with a size-separating screen at the outside (or 'bottom') of the flow will separate particles, with the fines passing through the outer wall screen, and the coarse material passing axially through the continuous feed system. Multiple size separation streams are possible. Alternate designs with shear-enhancing blades, 'above' or inside the screen, will also be evaluated. Various approaches for screen deblinding, and other robustness enhancements, are part of the proposed designs. With appropriate selection of passing-screen size, and deblinding enhancements, the centrifugal-sieves could be used for regolith processor feedstock conditioning to remove material > 0.5cm diameter, and with alternate settings and screen size, also used for a degree of beneficiation, to select particular size ranges that have the highest percentage of desired mineral content. The centrifugal-sieve concept can be scaled to any desired mass flow rate.

Summary
Description
Several solid waste management systems currently under development result in the production of gas-phase organic contaminants which, due to the periodic and unpredictable nature of solid wastes and contaminants produced by these systems, cannot be treated by the Trace Contaminant Control System. Two examples of these are the Heat Melt Compaction System under development at NASA - Ames Research Center and the Microwave Powered Solid Waste Stabilization and Water Recovery System under development at UMPQUA Research Company (URC). During the Phase I effort, we demonstrated the gas-phase catalytic oxidation of a variety of toxic organic compounds and carbon monoxide, with very high rates of conversion to innocuous gases, primarily CO2 and H2O, at relatively low temperatures. In the proposed Phase II effort both process and materials will be further refined to optimize the utility of the catalytic technology with respect to solid waste management goals. The Phase II research and development will result in the design, assembly, rigorous testing, and delivery to NASA of a prototype system, sized to operate in conjunction with both the NASA developed heat melt compaction system and the URC developed microwave waste stabilization and water recovery system.
