The response of the engineering system is often obtained by the use of numerical methods such as finite element method or boundary element method. However, the uncertainty of the acquired solutions cannot be measured using conventional methods. This uncertainty is attributed to two sources: errors in mathematical modeling and uncertainties in the parameter. The following paper addresses the second source of uncertainty for the steady state heat conduction problem where the material conductivity is uncertain. Material uncertainty is implemented into fuzzy boundary element method which obtains the exact worst case bounds on the response given the worst case bounds on the parameter uncertainty. The method assumes that a correct partial membership function is given. Numerical examples are shown to illustrate the behavior of the method. © 2010 SAE International.

ZIN Technologies, Inc will breadboard an integrated electronic system for space suit application to acquire images, biomedical sensor signals and suit health & status data. The system will then process, display, store, transmit and manage the results under control of embedded firmware. A commercial off-the-shelf heads-up display which is applicable to space suit helmets will be the primary display device. The system will include a breadboard version of a lightweight, low power, general purpose computing platform based on commercial-grade components with available, upgraded versions that can tolerate the EVA thermal/vacuum/radiation environment. Initial development of a camera interface will be included. A breadboard of the proposed system will be built, programmed and demonstrated. ZIN will leverage our past experience in NASA spaceflight hardware/software development and existing biomedical monitoring technology to deliver a mature concept demonstration at minimal cost and risk. The system will be compatible with medical industry standard sensors to measure CO2, core temperature and other biomedical parameters. The proposed Phase 1 effort will be geared toward future development of a Phase 2 version that could be integrated into a functional EVA system.

ZIN Technologies, Inc. will provide a preliminary design showing the feasibility of a Reconfigurable Multi-functional Architecture (RMA) for a deployable floor secondary structure.This will address NASA requirements for innovative deployable secondary structures that have minimal mass, high packaging efficiency, and multi-functional utilization. The primary usage of the floor will be to provide a light weight, deployable walkway for a habitat, which meets the appropriate strength, stiffness, and stability requirements. In Phase 1, ZIN will design, analyze and breadboard the necessary joints to enable the structure to be readily deployed and/or un-deployed, while maintaining the appropriate stiffness. The secondary purpose of the floor will be to take advantage of the walkway's cross sectional geometry and utilize it to provide water storage within the floor. The floor will house electrical and plumbing interfaces, which will connect these utilities between two sides of the module. An addition of electrical outlets within the structure will be provided upon need. Possible features include making the floor reconfigurable to serve as a radiation shield. ZIN will develop universal joints, to enable crew members to disassemble the flooring system and re-assemble it into other secondary or EVA structures. The proposed Phase 1 effort will be geared towards a full scale Phase 2 demonstrator, to show the floor system usage in a relevant environment and raise the Technology Readiness Level (TRL) of RMA structures. The RMA structure we propose will provide a highly robust, stiff and mass efficient surface within a primary structure that will enable the useful outfitting and pre-integration of subsystems within the primary volume

BioWATCH is a modular ambulatory compact wireless biomedical data acquisition system. More specifically, it is a data acquisition unit for acquiring signals from biomedical sensors using modular acquisition modules attached to a common data and power bus. Several module slots allow the user to configure the unit by inserting sensor specific modules. The data is then sent real time from the unit over any commercially implemented wireless network including 802.11b/g, WCDMA, GSM, or EDGE. BioWATCH is of a distributed computing hierarchy and has a common data controller on each sensor module. This innovation allows for the modularity of the device along with the tailored ability to control the cards using a relatively small master processor. The distributed nature of this system affords the modularity, size, and power consumption that betters the current state-of-the-art in medical ambulatory data acquisition. The current state-of-the-art in biomedical data monitoring is limited in its modularity and relies on centralized computing models.
