Abstract: An automated self-propelled pool cleaner having a housing, a water pump for moving water through the housing, drive means for moving the pool cleaner over the surface of the salt water pool to be cleaned, and an integral electrochemical chlorine generator mounted in the housing, includes a processor/controller that is programmed to activate the chlorine generator, the pump and drive means in predetermined operational sequences that minimize wear and tear on the water pump and drive means, while at the same time distribute and maintain a safe level of sanitizing chlorine in the pool, to thereby obviate the need for an in-line chlorinator or other chemical additive treatments; an optional automated sensor device can be provided to activate a secondary maintenance program which enables the pool cleaner to operate over prolonged periods of time as the sole means for filtering and sanitizing the pool water.

Abstract: An ultraviolet sterilization unit having a housing attached to an air heating and cooling system. The housing including two apertures into which lamp cartridges are inserted. The lamp cartridges carrying ultraviolet lamps operating in a frequency capable of sterilizing air within the system. The cartridges are configured to automatically de-energize the lamps when a lamp cartridge is removed from the housing. When the sterilization unit is a multiple lamp system, when one of the lamp cartridges is removed all lamps are de-energized. The de-energizing of the lamps occurring before a user will view the lamp.

Abstract: A self-contained oil spill cleanup craft and method which operates well in both rough and calm seas, is rapidly deployed, which provides high flow rate continuous separation and processing of recovered oil and water mixtures, and outputs water which is substantially free of oil and oil which is substantially free of water and other contaminants and, as such, refinery ready without further processing. The craft of the present invention can be used, for example, to clean up light and medium weight crude oil, lubricating oil, or diesel fuel that is floating on the surfaces of either fresh or salt water.
