  • Publication number: 20120255857
    Abstract: Disclosed herein is a method for reducing hardened chemical salts in soil and also for improving water quality in irrigating water. The method comprises an electrolysis system in contact with soil to reduce hardened chemical salts. The system also can reduce pest's activity in water through electrolysis and the release of metal ions. The treated water is used further to loosen soil, inhibit pest and disease outbreak in crop field, and improve productivity.

  • Publication number: 20100016701
    Abstract: A flexible electrode assembly comprises a central portion having electrical contacts disposed thereon and a plurality of elongated portions extending radially outwards from the central portion. One or more of the elongated portions has an electrode disposed in the vicinity of a distal end thereof. The electrodes are electrically coupled to respective ones of the electrical contacts disposed on the central portion. An apparatus for measuring electrophysiological signals in a human or animal body that incorporates the flexible electrode assembly is also disclosed.

  • Patent number: 7442305
    Abstract: Disclosed herein is a method for the removal of petroleum hydrocarbon and toxic constitutes from contaminated soils and sediment. The method comprises the removal of contaminated materials from soils and performs bioremediation for the removed contaminated materials in an efficient mode. The remained contaminated materials in the soils are biologically stabilized to allow microorganisms to grow and to consume the remained contaminated materials in the soils.

  • Publication number: 20070156359
    Abstract: The present invention relates generally to a method and apparatus utilized in hydrocarbon exploration. More specifically, the present invention relates to the utilization of acoustic sources and receivers to determine acoustic properties of geologic formations as a logging tool traverses them, be it a wireline logging tool and/or a logging while drilling (LWD) tool. More particularly, the present invention is directed to methods of, and apparatus for, adaptive equalization of receivers to reduce and/or substantially eliminate sensitivity mismatch.

  • Publication number: 20030066750
    Abstract: An energy conversion system utilizes electrolytic combustion process to covert energy with given energy potential into energy with equal or higher energy potential. The energy conversion system utilizes energy from an energy storage device to electrolytically separate water into electrolytic products. The electrolytic products are fed into a combustion device with or without extra fuel to produce work for other applications or further to deliver work to a generator to generate electricity with equal or higher energy potential. If there is consistent supply of energy in the form of low energy potential, or if the air and extra fuel used in the combustion process contains sufficient combustible materials, the energy conversion system in the electrolytic combustion process becomes self-energy sufficient operation provided with continuous make up water supply.
