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: Provided are electrochemical devices that are rechargeable, where an electrolyte stream whose electrolyte is electrochemically inert is supplied to an ion concentrate compartment between a bipolar membrane and an electrode, thereby eliminating a potential for scale build-up. When strong or weak cation resins are used in a product compartment of an electrochemical device, acid water produced can be used to soak and clean an ion concentrate compartment next to an electrode, such as the cathode.

Such operations avoid the use of chemical additions for regeneration purposes. In addition the cells provided herein are amenable to small footprints for consumer and commercial applications such as: dishwashers, washing machines, coffee and espresso makers, ice makers, steam tables, car wash water sources, and steamers.
