Abstract: Systems and method for sanitizing a system using ultraviolet light. A system for sanitizing an object may comprise a housing defining a tunnel and a conveyor movable in a first direction to move an object through the tunnel from the entrance opening to the exit opening. A plurality of ultraviolet (UV) light sources may be positioned about the tunnel. A plurality of reflectors each may extend partially around a corresponding UV light source. Each reflector may be configured to collect UV light emission from the corresponding UV light source and provide a directional projection of UV light into the tunnel. At least one reflector may provide a directional projection of UV light that is angularly offset toward the exit opening of the tunnel and at least one reflector may provide a directional projection of UV light that is angularly offset toward the entrance opening of the tunnel.

Abstract: Devices, methods, and systems for disinfecting air and surfaces are described herein. The systems may include a source of light, a reflector, a motor, and a controller. The source of light may provide ultraviolet germicidal irradiation light and the light may be selectively provided. The reflector may extend along and/or around the source of light. The motor may be coupled to the reflector and cause the reflector to adjust relative to the source of light so as to direct light at different target locations. The controller may determine occupancy in a room in which the system is located. When the room is not occupied, the controller may cause the reflector to be adjusted to an unoccupied position. When the room is occupied, the controller may cause the reflector to be adjusted to an occupied position.

Abstract: A building control device comprising a wireless interface and a controller configured to monitor when the wireless interface becomes disconnected from the network. When the wireless interface becomes disconnected from the network, the controller may attempt to reconnect the wireless interface to the network and if successful, return to monitoring for when the wireless interface becomes disconnected from the network. If not successful, the controller may switch the wireless interface into a configuration mode to establish a direct wireless connection with a remote device, receive updated network credentials from the remote device while in the configuration mode, exit the configuration mode, and connect the wireless interface to the network or another network using the updated network credentials.
