Abstract: Embodiments of the invention relate to devices, systems, and methods for selectively emitting scent control material responsive to local conditions of a scent control device. The local conditions may dictate the effectiveness of a given set of output parameters of a scent control device. The scent control device accepts as input, one or more conditional inputs carrying information about the local conditions around the scent control device, such as weather conditions, elevation, barometric pressure, or functional status of the scent control device. Operational programs corresponding to the conditional inputs may be automatically selected based on the combination of conditional inputs to cause the output parameters of the scent control device to match or take into account the local conditions. The scent control device then outputs scent control material such as ozone at a rate effective to control one or more scents to a level that is not perceivable by animals or humans.

Abstract: A protective respirator that deactivates pathogens in a kill zone in front of a mouth and nose of a user by emitting Far UV-C radiation (e.g., having a wavelength centered around 222 nanometers). In some embodiments, a controller uses a mathematical model to determine a required intensity or emission time to provide a threshold probability of killing a microbe (e.g., a virus such as SARS-CoV-2). The required intensity or time may be determined based on atmospheric conditions and/or physiological conditions of the user. The Far UV-C radiation may be emitted in a direction through the kill zone that does not intersect with the skin or eyes of the user (e.g., away from the user or across the front of the user's face). Alternatively, the controller may estimate the fluence of Far UV-C radiation at the skin or eyes of the user over time and adjust the Far UV-C radiation emitted.

Abstract: A self-sanitizing surface structure configured to selectively refract light, a method of fabricating a self-sanitizing surface configured to selectively refract light, and a method of decontaminating a surface using selectively refracted light. A waveguide including a support layer below a propagating layer is positioned over a substrate as a self-sanitizing layer. In the absence of a contaminant or residue on the waveguide, UV light injected into the propagating layer is constrained within the propagating layer due to total internal reflection. When a residue is present on the self-sanitizing surface structure, light may be selectively refracted at or near the interface with the residue along the side of the waveguide to destroy the residue. The self-sanitizing surface structure may be configured to refract a suitable amount of UV light in response to a particular type of residue or application.

Abstract: The invention is a disinfecting HVAC system that combines thermal displacement ventilation technology with UV-C light technology to isolate, concentrate, and/or kill harmful microorganisms (such as SARS-Cov-2) present in enclosed spaces. The system includes a single manifold collection pipe placed adjacent to the ceiling (e.g., about 12-14 feet above the floor). The collection pipe has a high collection efficiency when connected to an HVAC air handler and booster fan tandem. In the air handler, the warm air is cooled and treated with a sufficient dose of UV-C light to inactivate any microorganisms within a short amount of time. The UV-C treated air is then returned to the enclosed space through a plurality of low velocity diffusers.

Abstract: An example luminaire includes a white light source (e.g. LEDs emitting white light in a region of the CIE color chart within three Macadam ellipses below the black body curve) and a violet light source emitting light in a wavelength range of approximately 380 nm to 450 nm (e.g. 405 nm LEDs) for deactivating bacteria, such as Methicillin-Resistant Staphylococcus Aureus (MRSA) on a surface exposed to illumination from the luminaire. A controller coupled to the sources pulses the violet light source at periodic intervals or at random times. When ON, the violet source emits light for deactivating bacteria at an intensity higher than the concurrent intensity of the white light.
