    Abstract: A UV treatment cartridge having an exterior housing and a UV treatment module located inside of the exterior housing. The UV treatment module having a UVLED array for UV treatment of a fluid passing through the UV treatment module. An internal annular space between the exterior sidewall and the module sidewall forms an entry flow path to the UV treatment module thereby substantially balancing fluid pressure acting on the inside of the module sidewall and acting on the outside of the module sidewall.

    Abstract: A system includes multiple devices configured to emit and detect germicidal radiation. Each of the multiple devices operates in emitting mode when connected to a drive source in a forward bias configuration and operates in detecting mode when disconnected from the drive source or when connected to the drive source in a reverse bias configuration. Cycling circuitry generates a sequence of control signals that control switching circuitry to change the connections of the devices to the drive source in a cycle in which one or more of the multiple devices are switched to detecting mode and senses radiation emitted by one or more of the multiple devices simultaneously operating in emitting mode. Each device operating in detecting mode generates a signal in response to the sensed radiation. Detection circuitry detects signals of the devices operating in detecting mode and generates a detection output in response to the detected signals.

    Abstract: Illumination articles are described. More specifically, illumination articles that include a wearable device configured for wearing on the head of a wearer, a lightguide and light sources for emitting light into the lightguide are described. The illumination articles allow for wearable devices that uniformly illuminate a working area at high brightness without providing excessive glare to observers. The disclosed illumination article comprises: a wearable device configured for wearing on the head of a wearer, a lightguide disposed on the wearable device, wherein the lightguide is elongated and has a first end and a second end opposite the first end, and a first light source positioned at the first end, for emitting light into the lightguide. The lightguide further comprises a light emitting surface extending generally in an x-direction between the first and second end, and a light reflecting surface positioned opposite to the light emitting surface, wherein the light reflecting surface comprises a plurality of light extractors configured for directing light in a y-direction perpendicular to the x-direction, and wherein the light emitting surface is configured for directing light into an xy-plane.
