Abstract:
A system and method of disinfecting an area using germicidal radiation. The system is configured to capture images of an environment, analyze the images to determine locations of a person or unprotected skin of a person in the environment, and control one or more germicidal radiation emitters to decontaminate the environment where the person or exposed skin of persons in the environment are not located. The system and method allow for safe decontamination of an environment using hazardous levels of germicidal radiation while occupied by a person who may not be fully protected from the radiation.
Abstract:
A system and method of disinfecting an area using germicidal radiation. The system is configured to track person within the environment, and to control one or more germicidal radiation emitters based on user and sensor inputs, such as detecting whether the eyes are protected for the persons in this environment. The system is configured to intentionally and safely expose persons in the environment to germicidal radiation. This provides for safe, electronically controlled, direct decontamination of the surfaces, air, and persons in the environment.

Abstract:
A process for making an aqueous dispersion of fluoropolymer particles by polymerizing in a first polymerization step at least one fluohnated monomer having an ionic group in an aqueous polymerization medium in the presence of initiator, the polymerizing providing dispersed particulate of fluohnated ionomer, and polymerizing in a second polymerization step at least one fluohnated monomer in the aqueous polymerization medium in the presence of the dispersed particulate of fluohnated ionomer and initiator to form the aqueous dispersion of particles of fluoropolymer.
Abstract:
The presently disclosed subject matter is directed to a system and method of disinfecting an occupied outdoor or indoor environment comprising unprotected persons using direct irradiation. As a first step, the average amount of flux or irradiance of germicidal radiation determined to safe for exposure by unprotected persons is calculated (e.g., "occupancy time" or "maximum allowable occupancy time") before a daily maximum allowable dose of the emitted germicidal radiation in a 24-hour period is determined. The disclosed system and method also include delivering a uniform level, flux, or irradiance of radiation into the environment wherein the environment and persons present within the environment are disinfected.
