VIRTUAL DIAL IRRIGATION CONTROLLER

摘要

An irrigation controller (108) that has a virtual rotary dial (100) having the shape of a nine pointed star. Each arm (104) of the star is comprised of or part of a liquid crystal display, which, when energized, takes on an opaque color. When an arm (104) is opaque, this indicates that the controller (108) is in the mode that is identified on the controller face that corresponds to the opaque arm of the star. For example, when the arm (104) of the star near the words "Manual" is opaque, this means that the irrigation controller (108) is in the "manual" mode.
