Abstract: A chlorinator includes an electrode assembly and a housing. The housing includes a first water flow opening, a second water flow opening, an electrolysis chamber for accommodating the electrode assembly, a sampling chamber for selectively enabling sampling of water entering the housing in operation of the chlorinator, and a flow stream separator. The flow stream separator includes a partition wall axially extending between a first partition edge and a second partition edge. The partition wall separates the housing internal volume into a main channel and an auxiliary channel. The main channel extends axially between the first partition edge and the second partition edge, and wholly accommodates therein the electrolysis chamber on a first side of the partition wall. The auxiliary channel extends axially between the first partition edge and the second partition edge and wholly accommodates therein the sampling chamber on a second side of the partition wall.

Abstract: Device, system, and method of interactive communications among mobile devices and Internet Protocol (IP) connected screens. A system enables rapid and efficient generation of an interactive application, that has a screen-side component able to nm on IP-connected screen, and that has a mobile-side component able to run on smartphones, tablets, smart-watches, and other mobile electronic devices. User feedback from an end-Dashboard Module user device, or aggregated user feedback from multiple end-user devices, interacts with and affects the interactive application as displayed on the IP-connected screen. The system enables the interactive application to run and to operate automatically at a sports venue, a digital billboard or digital sign, or at other suitable venues.
