    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.

    IPC: C02F1/32

    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: Provided are flexible panel devices that use desiccants for heat and mass transfer processes, including but not limited to air conditioning systems, for example, liquid desiccant air conditioning (LDAC) applications wherein the liquid desiccant is contained in a panel that comprises at least one hydrophilic separation layer, which allows water vapor transfer between the air and liquid desiccant and enable dehumidification and humidification of the air. The flexible panel devices can be installed on an absorber (conditioner) side or a desorber (regenerator) side or both of a LDAC system. The devices have two flexible layers, at least one of which comprises a flexible and water vapor permeable hydrophilic separation layer, that form a desiccant flow channel and a desiccant flow distributor located therein. The two flexible layers may both be permeable hydropholic separation layers, or they may comprise one permeable hydrophilic separation layer along with another layer that may be a non-porous structure or a water-vapor permeable hydrophobic separation layer.
