Abstract: Systems and methods for detecting a site maintenance operation done by a maintenance device are described. At least one motion sensor and at least one localization sensor can each be operatively coupled to the maintenance device to detect one or more motion parameters of the maintenance device via the motion sensor and the localization sensor. The maintenance device can be localized (e.g., its position located) on the indoor map. A movement of the maintenance device can be characterized and/or tracked on the indoor map. A motion map can be displayed to illustrate (e.g., visually represent) the characterized movement. An offsite computer can be used to determine whether the site maintenance operation has commenced at the indoor location, measure one or more maintenance parameters of the site maintenance operation and/or compare the one or more maintenance parameters to predetermined benchmark parameters to determine whether the site maintenance operation has been completed.

Abstract: A system and method for generating hypochlorous acid, the system comprising an electrolysis cell, a first fluid line configured to direct a first salt solution to a cathode chamber of the electrolysis cell, and a second fluid line configured to direct a second salt solution to an anode chamber of the electrolysis cell, where the second salt solution has a greater salt concentration than the first salt solution.

Abstract: A system and method for generating and dispensing a diluted electrolyzed solution, where the system includes a solution generator, one or more containers, and one or more dispensing stations separate from the solution generator. The solution generator generates and dispenses a concentrated electrolyzed solution to the container(s). The dispensing station(s) draw the concentrated electrolyzed solution from the container(s), dilutes the drawn concentrated electrolyzed solution, and dispenses the diluted electrolyzed solution.

Abstract: The invention features a device for generating a plume of water, the device including a) a first side wall, b) a second side wall extending at an angle to the first side wall, the first side wall and the second side wall defining a tapered channel, the channel including i) a first end, ii) a second end, and iii) a longitudinal extent extending between the first end and the second end, c) a first flange extending at an angle to the first side wall, and d) a second flange extending at an angle to the second side wall.
