Abstract: Personal sanitizing headwear comprising a body adapted to fit onto a head of a user and an extended portion attached to the body and adapted for extending proximate a face of the user when the user is wearing the personal sanitizing headwear. The personal sanitizing headwear also includes one or more UV-C sources attached to a lower surface of the extended portion for directing UV-C radiation toward the mouth and/or nose of the user, wherein the one or more UV-C sources are adapted for sanitizing air in the proximity of the mouth and/or nose of the user.

Abstract: A sanitizing device includes a nonlinear optical element, one or more laser diodes, a lens, and a battery pack. The one or more laser diodes are each configured to direct a beam of optical energy to the nonlinear optical element. Each beam of optical energy has a first wavelength and the nonlinear optical element is configured to produce UV-C energy having a second wavelength from the beams of optical energy. The lens is configured to focus the UV-C energy to cover a desired area for sanitizing purposes. The battery pack is configured for powering the one or more laser diodes.

Abstract: A personal sanitizing device includes an eyewear frame and one or more UV-C sources attached to a lower edge of the eyewear frame for directing UV-C energy in a downward direction from the eyewear frame. The one or more UV-C sources are configured for sanitizing air in proximity of a mouth and/or a nose of a wearer of the personal sanitizing device. The personal sanitizing device also includes a battery configured for powering the one or more UV-C sources.
