REDUCING MAINTENANCE COSTS ON THE SHUTTLE PROGRAMGladney, Ed 10 1900 (has links)
International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / NASA and Lockheed Martin Telemetry & Instrumentation have jointly developed a new
data acquisition system for the Space Shuttle program. The system incorporates new
technologies which will greatly reduce manpower requirements by automating many of the
functions necessary to prepare the data acquisition system for each shuttle launch. This
new system, the Automated Data Acquisition System (ADAS), is capable of configuring
itself for each measurement without operator intervention. The key components of the
ADAS are the Universal Signal Conditioning Amplifier (USCA), the Transducer
Electronic Data Sheet (TEDS), and the Data Acquisition System (DAS 450). The ADAS is
currently being delivered and installed at Kennedy Space Center. NASA and Telemetry &
Instrumentation are actively pursuing commercialization of the ADAS and its associated
products which will be available during 1996.

Low energy, wind catcher assisted indirect-evaporative cooling system for building applicationsElzaidabi, Abdalla Ali Mohamed January 2009 (has links)
Increased consciousness of the environmental problems has aroused people’s interest of renewable energy systems, especially the application of green features in buildings. The demand for air conditioning / cooling in domestic and non-domestic buildings is rising throughout the world; this increases the reliance on conventional fuels and the global warming effect from greenhouse gas emissions. Passive cooling and energy efficient design can substantially reduce reliance on fuel based heating and cooling. Passive and Hybrid Downdraught Cooling, in different forms, is now technically viable in many parts of the world. This has been established through a combination of research projects. In some hot arid regions, a major part of the energy consumed consists of air-conditioning requirements. Alternative methods, using passive cooling techniques, can assist in reducing the conventional energy consumption in buildings. Evaporative cooling, which can be tracked back several hundreds of years in ancient Egypt and Persia [1–3], is one of the most effective strategies, because of the enormous latent heat needed for evaporation of water. Green features are architectural features used to mitigate migration of various air-borne pollutants and transmission of air from outside to indoor environment in an advantageous way [9]. The reduction of fossil fuel consumption and the associated decrease in greenhouse gas emissions are vital to combat global warming and this can be accomplished, in part, by the use of natural ventilation. To assess the performance of several innovative cooling systems devices and to develop improved models for more established technology, quantitative measurement of output was necessary. This was achieved in this study by the development of simply constructed low energy cooling systems which were calibrated by the innovative use of wind and water as a source. These devices were found to be consistent and accurate in measuring the temperature and cooling load from a number of devices. There were some problems in the original evaporative units. Therefore, a number of modifications have to be made to enhance the systems performance. The novel Windcatcher – PEC cooling system was assessed and different cooling loads were achieved.
