  • Publication number: 20220355233
    Abstract: A method of monitoring indoor environments for aerosolized pathogens includes: (a) receiving a pathogen status for each of a plurality of aerosol samples collected by a plurality of corresponding air treatment devices; (b) determining whether the pathogen status for each aerosol sample changes a safety status of a corresponding indoor environment from which the aerosol sample was collected; and (c) in response to determining a change in the safety status, generating a notification associated with the change in the safety status for the corresponding indoor environment.

  • Publication number: 20210286201
    Abstract: An adjustable optic device for providing light field information includes: (a) at least one counter electrode; (b) one or more working electrodes; (c) an insulating framework separating the counter electrode from each working electrode; and (d) an electrolyte medium between the counter electrode and the one or more working electrodes. Each working electrode is reversibly transitionable from a stripped state toward a plated state when a plating charge voltage is applied to induce plating with ions from the electrolyte medium. When in the stripped state, the one or more working electrodes are transparent and present a passage through the optic device for transmission of electromagnetic radiation. When in the plated state, the one or more working electrodes are plated with ions from the electrolyte medium to provide a coded aperture in the passage. The coded aperture has a pattern of subapertures for providing light field information.
