  • Patent number: 9001487
    Abstract: An ionizer includes an electrode shaft, a fixing bar, a driver, and a controller. The electrode shaft includes first and second electrode rows, the first electrode row having a plurality of ionizer electrodes arranged in a first direction and the second electrode row having a plurality of ionizer electrodes arranged in the first direction and spaced apart from the first electrode row. The fixing bar includes a discharge area facing an object to be processed, and accommodates the electrode shaft so a single electrode row is disposed in the discharge area. The driver is inside the fixing bar so as to be coupled to both end portions of the electrode shaft, and controls a position of the electrode shaft. The controller controls the driver to replace the electrode row disposed in the discharge area with another electrode row according to a previously input replacement condition.

  • Patent number: 8988847
    Abstract: The invention concerns environmentally compatible methods and apparatuses for local modification of atmosphere, and in particular, for causing precipitation, dissipating fogs and/or clouds, removing air-pollutants in a target area. SUBSTANCE: the method involves applying air ionizers (1a, 1b, 1c) to generate ion flows into atmosphere to form convective flows and/or spatial charges. To control characteristics of the ion flow, it is proposed to use one or multiple air ionizers (1a, 1b, 1c) provided with variable-inclination electrode working cells. EFFECT: wide application of an air ionizer (1) with variable layout (inclination angle) of the electrodes in weather condition modification over a target area.

  • Publication number: 20150070812
    Abstract: An air ionizing apparatus for enhancing plant growth that includes a housing, solar cells mounted atop the housing, a voltage regulator/conditioner circuit coupled to the solar cells, an oscillator/modulator circuit coupled to the voltage regulator/conditioner circuit, a high voltage converter/multiplier circuit coupled to the oscillator/modulator circuit, and an ion emitter element coupled to the high/voltage converter/multiplier circuit and disposed at the bottom of the housing. Solar energy transferred to the solar cells and converted into current is converted to high voltage through the voltage/regulator, oscillator/modulator, and high voltage converter/multiplier circuits. The high voltage is then applied to the ion emitter element to produce ions from ambient air in close proximity to a plant being treated.
