Systems and methods for detecting presence of a thing, the thing treated with a descenter, one method including in an area in which it is possible that a thing treated with a descenter is present, using a detector to detect a descenter level in the area, producing a detected descenter level, comparing the detected descenter level to a normal descenter level for the area, determining that the detected descenter level is different from the normal descenter level, said determining indicating the possible presence of a thing treated with a descenter; and using a trained service animal to facilitate such a method.

An eyeglass device for inactivating a pathogen includes an eyeglass frame connectable with a face of a person and a pair of lenses connected with the eyeglass frame. The pair of lenses includes a composition that blocks some wavelengths of beams of ultraviolet light. The eyeglass device further includes a light affixed to the eyeglass frame and that emits an ultraviolet light beam having a wavelength of about 205 nm to about 225 nm and does not emit an ultraviolet light beam having a wavelength of about 254 nm. Methods of inactivating a pathogen are also described.

Systems and methods for detecting presence of a thing, the thing treated with a descenter, one method including in an area in which it is possible that a thing treated with a descenter is present, using a detector to detect a descenter level in the area, producing a detected descenter level, comparing the detected descenter level to a normal descenter level for the area, determining that the detected descenter level is different from the normal descenter level, said determining indicating the possible presence of a thing treated with a descenter; and using a trained service animal to facilitate such a method.

Methods and devices for formulating scented nanoemulsions and dispersing one or more scents is disclosed. In some embodiments, the method includes providing a first mixture including water and a water surfactant, providing a second mixture including a fragrance material and an fragrance surfactant, mixing the first and second mixtures to create a temporary emulsion, and performing one or more high-energy homogenizations to the temporary emulsion until one or more desired physical properties of a resulting nanoemulsion are obtained. In some embodiments, the one or more high-energy homogenizations includes microfludization, sonication, and high-shear mixing. In some embodiments, the resulting nanoemulsion may thereafter be dispersed as a scent via an aerosolizing device. In some embodiments, the aerosolizing device may disburse scents in response to actions and/or events experienced in an AV/AR system.
