  • Patent number: 12041992
    Abstract: Various embodiments are directed to a diffuser headband system. The system may include a diffuser headband formed from an elastic material coupled to a sanitized air generating source that produces sanitized air. The diffuser headband may form a substantially oval shape and include an elastic tube attached to the elastic material. A first portion of the elastic tube may be perforated to include a group of air outlet holes spaced along a surface of the elastic tube. A second portion of the elastic tube may include an inlet that receives the sanitized air from the sanitized air generating source. The air outlet holes receive the sanitized air from the inlet and expel the sanitized air to provide an air shield that encircles a person's body wearing the diffuser headband. The air shield blocks viral aerosol droplets from entering or leaving an airspace occupied by the person wearing the diffuser headband.

  • Patent number: 12005394
    Abstract: An arrangement and process of mitigating contaminants has a flow element intermediate a first space with contaminated matter (including contaminated gas) and a second space. Contaminated matter is drawn from the first space into the flow element and then urged into segregated contaminated gas and residual contaminated matter collected in the second space. Segregated contaminated gas is merged with gas from the second space to form mixed gas and treated to form primary treated gas which is directed to generate at least some of the drawing of contaminated matter from the first space into the flow element. Mixed gas can be treated by passing it through passages in the flow element coated with decontaminating agent and/or through a decontamination unit. The flow element allows for air flow to effectively act as a one-way barrier obstructing migration of contaminated matter from the second space back to the first space.
