Abstract: An ultraviolet emitting device comprising a plurality of light sources; and a plurality of arms on which the plurality of light sources are mounted, wherein: each arm is expandable between a first position and a second position, each arm is fully collapsed in the first position and fully expanded in the second position, and when each arm is transitioning between the first position and the second position, a length of the arm maintains a fixed proportionality with respect to a spacing of the plurality of light sources on the arm.

Abstract: The implementations include a system configured to automatically deposit a variable film of an inoculant containing one or more pathogens, the system including: a base configured with a receptacle for a removable chamber; a liquid inlet receiver configured to provide the inoculant from a liquid inlet thereon to the removable chamber; a gas inlet configured to provide a pressurized gas from a gas tank to the removable chamber; and an adjustable nozzle configured to spray the inoculant from the liquid inlet and under the pressurized gas from the gas inlet.

Abstract: An ultraviolet emitting system for sanitizing a target volume can include a plurality of adjustably positionable light sources having a collapsed position and the expanded position. The light sources of the plurality of adjustably positionable light sources can be configured to emit ultraviolet light in a substantially homogenous irradiance within the target volume in any position between the collapsed position and the expanded position.

Abstract: A Sterilization Unit includes: a UV-C radiation source configured to emit UV-C radiation; and a room partition selectably configurable between two or more different partition geometrics and configured, in each of the two or more different partition geometrics, to (a) physically separate floor space of a room into sterilization target area and a non-target area, and (b) direct the UV-C radiation to the target area from at least two different directions while shielding the non-target area from the UV-C radiation.
