Abstract: The invention is directed to an article with a liquid-impregnated surface, the surface having a matrix of features thereupon, spaced sufficiently close to stably contain a liquid therebetween or therewithin, and preferable also a thin film thereupon. The surface provides the article with advantageous non-wetting properties. Compared to previous non-wetting surfaces, which include a gas (e.g., air) entrained within surface textures, these liquid-impregnated surfaces are resistant to impalement and frost formation, and are therefore more robust.

Also provided are methods for preparing electrodes and electrode assemblies, and methods of filling liquid electrolyte into electrode assemblies. Electric vehicle systems comprising the electrode assemblies are also provided.

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: The descriptions relate to preventing assembly of a fluid filter apparatus unless a filter cartridge is installed, and preventing assembly of a fluid filter apparatus if the incorrect filter cartridge is installed. A mechanism includes cooperation of a movable member and a structure that can move the movable member to ensure that a fluid filter apparatus cannot be completely assembled, for example connecting its filter head to its shell, when there is no cartridge installed inside the shell or when there is an attempt to install an incorrect cartridge. This can protect from an inadvertent or intentional failure to install a cartridge (or correct cartridge) in the fluid filter apparatus.

Abstract: Disclosed are filter assembly systems that utilize replaceable filter elements. The filter elements may include a ramp or sleeve for redirecting air intake when the filter elements are installed in the filter assembly systems and air is drawn into the systems. The filter elements and assembly systems may utilize co-acting components that mate with each other to at least one of: a) orient and permit mounting of the filter element in the systems; and b) permit mounting of only an authorized filter element in the systems.
