In 2007, the U.S. Supreme Court ruled that carbon dioxide (CO2) is a pollutant under the federal Clean Air Act. The ruling allows the EPA to regulate CO2 emissions. Such regulation will entail monitoring a wide variety of pollution sources including automobile exhaust systems, industrial emission sources, and carbon sequestration sites. With presently available technologies, EPA personnel will ...

The overall goal of this multi-phase project is the development of a system that will help individuals orient themselves and safely navigate in vocational environments. The system will also be designed to assist individuals in finding and identifying items and objects. Various strategies and technologies have been introduced to provide navigation assistance, including devices that support audio ...

The three primary drive systems for power wheelchairs-front, middle and rear wheel drives-have a wide range of advantages and disadvantages. Users select the drive system based on their individual needs. Currently, no power wheelchair has a variable position drive system that the power wheelchair user can automatically move fore/aft through a range that will provide the benefits of rear, middle ...

In the U.S., several high profile outbreaks of waterborne illness during the past 15 years have highlighted the need for solutions to drinking water contamination. Several recent studies suggest that approximately 20% of the surface and ground source waters in the U.S. are contaminated with viruses. However, there is very little data on virus occurrence in drinking water, which is mostly due to ...
