    Abstract: An Environmental Control System may use an electronic air treatment system to control humidity in an aircraft. The electronic air treatment system may use an electronic charging system and a separation system. A turbine rotor may drive a power generating stage to provide high voltage power to the electronic charging system. The charging stage may charge airflow passing through to repel liquid particles away from the airflow. Liquid droplets may be collected and centrifugally flung toward a periphery of the separation system. The liquid particles may be collected outside of the airflow, which may be allowed to pass through the separation system and out to a destination in the aircraft without the collected liquid.

    Abstract: Disclosed is an air purification filter with novel active media that attracts, migrates, binds, and destroys pathogens, including sub-micron pathogens, that are suspended in the air passing through the filter. These properties are incorporated in the micro-fibers comprising the active filter media by several novel methods. One embodiment uses polymers or solgel bound monomers of quaternary ammonium compounds as a biocide with both chemotactic and pathogen membrane lysing properties. Another embodiment uses biocide chemicals blended into the melt before filter fibers are extruded and electret dipole charged. The attracting-binding properties of the embodiments may be enhanced by including electropositive Boehmite nano-fiber strands in the active media, by coating a reversible voltage charged electro-conductive polymer, by the use of supplemental fusing and lysing chemicals, and by optional ion field charging of incoming pathogens.

    Abstract: The present invention provides an electrically driven oxygen separation assembly and method of applying an electrical potential thereto in which one or more tubular membrane elements are provided having an anode layer, a cathode layer, an electrolyte layer and two current collector layers adjacent to and in contact with the anode layer and the cathode layer and situated on the inside and outside of the at least one tubular membrane element. The potential is applied to one of the two current collector layers at two central spaced locations of the at least one tubular membrane element and to the other of the two current collector layers at least at opposite end locations thereof. As a result the electric current flow through the tubular membrane element is divided into two parts flowing between the two central spaced locations and the opposite end locations.

  • Publication number: 20100077924
    Abstract: The present invention relates to air purification techniques and provides an air purifier. The air purifier comprises a shell with an air inlet and an air outlet. An electric field filter, an air passage and a blower are disposed inside the shell. The electric field filter comprises a filter frame disposed at the air outlet and a grid base disposed under the filter frame. A filter is provided inside the filter frame. One end of the air passage connects with the grid base and the other end connects with the blower. The blower is disposed at the air inlet. The filter frame and the grid base are integrated as a hermetic whole. Due to the integrated configuration of the filter frame and the grid base, when removing out the electric field filter, the power is cut automatically. This effectively prevents an occurrence of the electroshock, and improves safety performance of the purifier. Furthermore, air leakage can be greatly reduced, for there is no gap between the filter frame and the grid base.

  • Publication number: 20100037776
    Abstract: Air or gas cleaners enhance the uniformity of the current density between an emitter and one or more receptor electrodes by positioning one or more insulators or effective resistors between the emitter and the receptor electrode. Insulators and/or effective resistors are used to shield select portions, e.g. the edges of plate-type receptor electrodes, from ionization current flowing between an emitter and unshielded portions. This allows more compact structures without ionization current concentrations at the shielded regions, and results in lower ozone generation for a given particle collection efficiency.
