Abstract: A method of treating contaminated air, gas and surfaces is accomplished through the nebulization of gas and/or liquid oxidants through a field of electromagnetic radiation or sonic waves. The contaminated gas and/or liquid streams are blended with gaseous and/or liquid oxidants by the nebulizer and directly injected in the energy field. Free radicals produced from oxidants in the presence of the energy field instantaneously oxidize a large effective surface area of the contaminated media. Surfaces are treated more efficiently with the energy field situated directly above and parallel to but not on the surface; a high-frequency energy field may be used to create a large concentration of free radicals without damaging the surface in a collimated beam of the field situated parallel to the surface. A catalyst may be employed at the tip (i.e. discharge orifices of gas and/or liquid) of the nebulizer or blended into the nebulized cloud to increase the formation of free radicals.

Abstract: A modular sensor switch is formed to include the sensor and electrical control elements in a base module which is covered by a removable and replaceable cover plate module that may be aesthetically coordinated with a suitable switch or cover plate. The cover plate module may be changed by a user without the services of an electrician. The cover plate module includes at least one sensor cover and at least one manual switch activator element that may be formed to aesthetically coordinate with a switch plate cover to create a unified decorative effect for the combined switch plate cover and cover plate module.

Abstract: The present invention provides a method for oxidizing a substance (e.g., in a waste stream, drinking water, a paper pulp slurry, or on a surface), which uses free radicals and reactive species generated from multiple oxidants. The method comprises combining peroxynitrite or peroxynitrous acid and at least one additional oxidizing agent for a period of time sufficient to oxidize the substance of interest. The peroxynitrite or peroxynitrous acid preferably is formed by irradiation of nitrate ion and/or nitric acid (e.g., with UV or gamma rays). The yield of free radicals and reactive species, which are the intermediate species that perform the oxidation may be increased by addition of a catalysts, electromagnetic radiation, sonic waves, and/or electrolysis.
