  • Patent number: 11633511
    Abstract: Infectious diseases can be transmitted to humans, or between humans and animals, by airborne viruses and bacteria, known as infectious aerosols. Current protective measures that individuals can take to avoid inhaling such aerosols are either marginally effective (personal face masks) or impractical (self-contained breathing apparatuses). Building ventilation systems employing high-efficiency filters to prevent distribution of such aerosols suffer from high energy costs and high filter replacement costs. The development of conventional, intramuscularly administered vaccines takes months or years to produce enough doses to protect a population from a rapidly spreading infectious disease. Airborne viruses and bacteria have been shown to be completely inactivated when exposed to non-thermal plasmas.

  • Publication number: 20220288552
    Abstract: A non-thermal plasma reactor system having an outer member; a non-thermal plasma inner member sleeve disposed within the outer member, the non-thermal plasma inner member sleeve having an central core volume, the non-thermal plasma inner member sleeve being smaller than the outer member to define an annular volume there between, the non-thermal plasma inner member sleeve having an inner surface boundary and an outer surface boundary to define a sleeve volume there between, the inner surface boundary and the outer surface boundary being permeable and configured to permit airflow between the annular volume and the central core volume; dielectric material being disposed within the sleeve volume; and at least one electrode extending within the sleeve volume and another electrode coupled to the inner sleeve member generating the non-thermal plasma contacting the airflow as it flows between the annular volume and the central core volume.

  • Publication number: 20220126126
    Abstract: A device receiving an unsterile supply of air, subjects the airflow to one or more sterilizing agents or sterilizing conditions, and then exhausts the treated airflow through a nozzle or array of nozzles, forming a jet of air or array of air jets directed at or along the surface of the head of a living being such that the sterilized airflow envelopes the head. The result is a) the living being breathes air that is free of one or more infectious agents and b) the jet of air forms an air curtain such that the living being is protected from inhaling infectious agents that may surround them.

  • Patent number: 11179490
    Abstract: A method and apparatus for electro-hydrodynamic destruction of an aerosol. The method includes receiving air having large aerosols, greater than about 1 micron, and small aerosols, smaller than about 1 micron, and entraining the large aerosols and small aerosols within an airflow. The airflow is directed to an electric field, which causes the large aerosols to react with the electric field to accumulate an electric charge resulting in extraction of the large aerosols from the airflow. The airflow is also directed to a non-thermal plasma such that the small aerosols remain entrained in the airflow and are subject to electro-hydrodynamic (EHD) phenomena. The non-thermal plasma outputs at least one of radicals, excited species, and ionized atoms and molecules capable of reacting with the small aerosols to result in physical and/or chemical destruction of the small aerosols.

  • Patent number: 7704461
    Abstract: Virtual sorbent bed systems and methods for receiving contaminants from a waste stream are presented. In an embodiment, the virtual sorbent bed system comprises an outlet for introducing into the gas stream a material capable of receiving contaminants, a first charged DC electrode oriented substantially peripheral to the gas stream and normal to the flow of the gas stream; a second charged DC electrode oriented substantially peripheral to the gas stream and normal to the flow of the gas stream, wherein the first DC charged electrode and the second charged DC electrode cooperatively generate a first electric field that imparts a drift velocity to the material; and a plurality of charged AC electrodes oriented substantially peripheral to the gas stream and normal to the flow of the gas stream, wherein the charged AC electrodes generates a second electric field that imparts additional three-dimensional motion to the material.
