A room sterilization system generates ultraviolet germicidal irradiation (UVGI) to decontaminate a room whenever the room is free of occupants. To achieve this, the sterilization system has a light fixture, and an environmental sensor. The light fixture is a lamp used to produce UVGI for sterilizing the room, and has a housing, a sterilizing light source, and a microcontroller. The sterilizing light source is a UVGI emitter that is mounted within the housing and electrically connected to the microcontroller. The environmental sensor monitors the room to detect the presence of an occupant and then alerts the microcontroller to deactivate the sterilizing light source if the occupant is detected.

A handheld portable device for sanitizing a surface or air surrounding a surface. The handheld portable device includes a body that comprises a user input and a UVC light source disposed at the body. The handheld portable device also includes a power source for providing power to the UVC light source. Responsive to actuating the user input, such as by a user holding the handheld portable device, the UVC light source emits UVC light to sanitize the surface or the air surrounding the surface of pathogens. The handheld portable device includes a visible light emitter that, when powered, emits visible light to indicate the surface or space that is irradiated by the UVC light.

The objective of the present invention is to provide a floor-selecting sanitary control panel of an elevator, the sanitary control panel being operated and used during boarding/exiting of an elevator that transports visitors up and down a skyscraper. If a floor-selection button of a corresponding floor is operated in order to choose a floor to be visited, a driving unit operates by means of the operation signal of an electric breaker linked to the floor-selection button, so as to alternately and automatically replace used portions of floor-selection buttons and surfaces to be used while rotating a button queue all at once, and thus, after a visitor uses a use surface of a floor-selection button on the control panel, the used surface is automatically replaced with a sterilized surface to be used, so that the spread of disease such as infection or contagion is prevented on the control panel.

A system and method reduce a concentration of viable microorganisms, including but not limited to the 2019 novel (new) coronavirus that causes the illness coronavirus disease 2019 (COVID-19), in air in a workspace by over 80% with a single pass of air through the system. A heater heats air drawn from the workspace and a desiccant dehumidifier further heats air from the heater. The heater and desiccant dehumidifier decontaminate the air to kill or inactivate the microorganisms so that air returned to the workspace from the system has a reduced concentration of viable microorganisms.
