  • Patent number: 10363327
    Abstract: A variety of applications for UV LEDs that are integrated into a system are described, where the UV light is used for disinfection of air or surfaces, or used to detect the scattering light by particles, or used for skin treatment. In one embodiment, a ceiling luminaire includes a sensor for detecting the presence of people in the room. The luminaire contains a first set of LEDs for generating white light, for illumination, and a second set of LEDs for generating UV light for disinfecting the room. When the sensor detects that no people are in the room, the system automatically controls the UV LEDs to turn on to disinfect the room. The white light LEDs may be independently controlled with a dimmer.

  • Patent number: 9339571
    Abstract: A solution for disinfecting a screen of an item using ultraviolet radiation is provided. The solution can provide an electronic device including a screen utilized by a user of the electronic device. The screen can be an ultraviolet transparent screen that covers at least some of the internal portion of the electronic device and a set of ultraviolet radiation sources can be located adjacent to the transparent screen. The set of ultraviolet radiation sources can be configured to generate ultraviolet radiation directed towards an external surface of the ultraviolet transparent screen. The electronic device can further include a monitoring and control system, which can manage the ultraviolet radiation generation by monitoring a set of attributes relating to the external surface of the screen and controlling, based on the monitoring, ultraviolet radiation directed at the external surface of the screen.

  • Patent number: 9321665
    Abstract: A water treatment device and methods of treating water such as cooling tower water, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components. Swimming pool water and hot tub water treated with the water treatment device typically requires less chlorine, and chlorine levels are typically more stable than without the device.

  • Patent number: 9272059
    Abstract: UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.

  • Patent number: 9265876
    Abstract: The systems and methods for pathogen reduction in donor blood operates by exposure of blood to UVC irradiation. Unwanted wavelengths of light, mostly in the infrared spectra, may be precluded from reaching blood by providing a layer of IR-absorbing fluid positioned between blood and the source of UV irradiation, whereby minimizing energy absorption and heating of blood. Some embodiments further disclose a system configured to utilize the same IR-absorbing fluid to actively cool blood by flowing along the flow path thereof.
