Abstract: A sanitization system for a space includes an ultraviolet (UV) light source configured to emit UV light towards a UV light zone at a UV light level, a motion sensor device configured to sense movements of one or more individuals, and a controller. The controller is configured to determine, based on the movements of the one or more individuals, an exposure parameter value for each of the one or more individuals in the UV light zone, determine that the value of the exposure parameter determined for at least one of the one or more individuals exceeds a threshold value, and, responsive to determining that the value of the exposure parameter determined for the at least one of the one or more individuals exceeds the threshold value, cause the UV light source to reduce the UV light level of the UV light emitted towards the UV light zone.

Abstract: A probe sterilization device is provided. The probe sterilization device including: a housing defining a cavity with an opening, the housing including a cover plate capable of covering the opening; a cover plate drive, capable of driving, in response to a cover plate drive control signal, the cover plate to move so as to open the opening; a support, arranged in the housing and capable of fixing the probe; an ultraviolet light source, arranged in the housing and capable of being turned on in response to a light source control signal; and a processor, electrically connected to the cover plate drive and capable of sending the cover plate drive control signal to the cover plate drive, and electrically connected to the ultraviolet light source and capable of sending the light source control signal to the ultraviolet light source.

Abstract: An apparatus for processing an artificial tooth with a disinfection and sterilization function includes: a work bed unit in which a tooth mother material selected from a titanium material or a zirconia material is installed and fixed, and in which a wet-type die that processes a titanium material and a dry-type die that processes a zirconia material are separately disposed; a processing tool unit that has a driving spindle to which a processing tool is coupled at an end thereof and that processes the tooth mother material while moving close to or away from the tooth mother material; and a disinfection/sterilization module that is coupled in a detachable type in the work bed unit and can simultaneously reduce powder and perform disinfection.

Abstract: The present invention relates to pathogen cleaning and simulation of pathogen spreading. More particularly, some implementations of the described invention relate to systems and methods for spraying materials in a manner that mimics the spreading of pathogens from coughing or sneezing. Some implementations further relate to using a non-aerosol sprayer that produces both a mist and droplets of a mixture containing water, a fluorescent marker, a surfactant, and an antifoaming agent. In some cases, the pump sprayer defines an internal compartment that includes the mixture. In some cases, the sprayer further includes a pump mechanism that is configured to be pumped to compress a gas within the compartment and a release valve that is configured to release pressure within the compartment through a spray nozzle of the sprayer such that droplets and mist of the mixture are sprayed from the nozzle. Other implementations are also described.

Abstract: An apparatus for exposing an article to radiant energy has a rotating carousel having an article support in a support sector defined between a first energy-blocking feature of the rotating carousel and a second energy-blocking feature of the rotating carousel. An actuator is energizable to rotate the carousel and to revolve the article support along a circular transport path. An enclosure has a stationary hood that defines an enclosed sector of the transport path and an unenclosed sector of the transport path. There is at least a first radiant energy source energizable to direct the radiant exposure energy toward the carousel along the enclosed sector of the transport path.
