Abstract: A solution for irradiating a flowing fluid through a channel with ultraviolet radiation is provided. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation based on the flow rate of the fluid and a user input component can receive a user input for the control system to adjust the ultraviolet radiation. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.

Abstract: An approach for controlling ultraviolet intensity over a surface of a light sensitive object is described. Aspects involve using ultraviolet radiation with a wavelength range that includes ultraviolet-A and ultraviolet-B radiation to irradiate the surface. Light sensors measure light intensity at the surface, wherein each sensor measures light intensity in a wavelength range that corresponds to a wavelength range emitted from at least one of the sources. A controller controls the light intensity over the surface by adjusting the power of the sources as a function of the light intensity measurements. The controller uses the light intensity measurements to determine whether each source is illuminating the surface with an intensity that is within an acceptable variation with a predetermined intensity value targeted for the surface. The controller adjusts the power of the sources as a function of the variation to ensure an optimal distribution of light intensity over the surface.

Abstract: A heterostructure with reduced optical losses is disclosed. The heterostructure includes a set of n-type layers; an active region that generates radiation at a peak emitted wavelength; and a set of p-type layers located adjacent to the active region. A reflective structure can be located adjacent to the set of p-type layers. A thickness of the set of p-type layers can be configured to promote constructive interference of the reflected radiation with radiation emitted by the active region in a direction toward the set of n-type layers.

Abstract: Aspects of the invention provide a system for disinfecting a humidifier containing a volume of water. An enclosure, such as a humidifier, includes a first chamber, a second chamber, a humidifier component, a third chamber, and a control unit. The first chamber contains a volume of water and a portion of the water flows into the second chamber. A first set of ultraviolet radiation sources within the first chamber can be configured to generate UV-A radiation, while a second set of ultraviolet radiation sources within the second chamber can be configured to generate UV-C radiation. In operation, the humidifier component adjacent to the second chamber creates water vapor using the portion of the volume of water within the second chamber. The water vapor flows into a third chamber that contains the water vapor and releases the water vapor into the ambient.

Abstract: Disinfection of a surface, such as a mouthpiece of a water bottle, using ultraviolet radiation is disclosed. A cover assembly can include a cover configured to selectively enclose the surface to be disinfected, such as the mouthpiece. The cover assembly can be configured such that ultraviolet radiation can be emitted into an interior volume at least partially formed by the cover and including the surface. The cover assembly can further include a power source which provides power to one or more ultraviolet light sources that emit the ultraviolet radiation. The cover assembly can be a mouthpiece cover assembly physically separate from a container and top cover or integrated in the top cover. A container and a top cover including one or more features for improved cleanliness are also disclosed.

Abstract: Approaches for evaluating fluid flow based on fluorescent sensing is disclosed. In one approach, a nanoparticle injector is configured to inject nanoparticles into fluid flowing through a conduit. A detector is configured to determine a presence of the nanoparticles in the flow of the fluid. The detector can include a radiation source configured to irradiate the fluid with a target radiation and a fluorescent meter configured to measure an amount of fluorescence emitted from the fluid irradiated with the radiation. A control unit is configured to determine the flow of the fluid in the conduit as a function of the measured amount of fluorescence.
