Abstract: Circuitry for identifying a misaligned wheeled irrigation tower within a plurality of wheeled irrigation towers is described. The circuitry includes a test resistance configured for installation in a center pivot irrigation system. The circuitry also includes a plurality of resistances. Each of the plurality of resistances is configured for installation in a wheeled irrigation tower of the center pivot irrigation system and to be coupled in series with the test resistance. Each of the plurality of resistances is configured to be coupled to a corresponding switch of a respective wheeled irrigation tower and a neutral line. The circuitry further includes detection circuitry coupled to the test resistance. The detection circuitry is configured, when installed in the center pivot irrigation system, to identify a misaligned wheeled irrigation tower of a plurality of wheeled irrigation towers based on a voltage corresponding to the test resistance.

Abstract: A system, method, and device may be used to provide irrigation water consumption data. The system may include an irrigation valve interface and controller that communicates with irrigation valves to open and close the valves. An identification module identifies one or more time periods when water consumption is not likely to occur or is likely minimal and a calibration module opens and closes the irrigation valves according to calibration schedule data. A timestamp module may identify a calibration valve open time and a calibration valve close time for the irrigation valves and a computational module may calculate a computed flow rate for the irrigation valves based on the calibration valve open time, the calibration valve close time, and the actual water usage data that occurred between the calibration valve open time and the calibration valve close time. The computed flow rate may be utilized to identify anomalies and provide notifications thereof.

Abstract: Irrigation line couplings are disclosed. The irrigation line couplings may each include a lockable release mechanism that may be positioned in a locked position or a released position. The irrigation line couplings may be incorporated into an irrigation manifold or other type of irrigation component, such as fittings (tees, elbows, etc.), valves, filters, pressure regulators, emitters, and adapters.

Abstract: An electronic device comprising memory and at least one processor coupled to the memory is disclosed. The at least one processor may be configured to render, on a user interface, a circular shape representing a center pivot irrigation system. The at least one processor may also be configured to receive a first input via the user interface indicating a first input point on the user interface. The at least one processor may also be configured to render, on the user interface, an alteration point marker on the circular shape at a first position aligned with the first input point and a center of the circular shape. The first position of the alteration point marker corresponding to a first radial position of the pivot. The at least one processor may be configured to control the center pivot irrigation system to alter operation of the pivot at the first radial position.

Abstract: A variable pressure regulator defining a distance between a proximal end of a piston and a floor of a piston seat is disclosed. Adjustment mechanisms for adjusting this distance to alter output pressure are disclosed.

Abstract: An enhanced seal may comprise an inner portion and an outer portion. The inner portion may comprise an inner cylindrical portion and an inner annular portion. The outer portion may comprise an outer cylindrical portion and an outer annular portion. The inner portion may be made of a harder material than the outer portion and may provide support to the outer portion.

Abstract: An irrigation controller is disclosed together with associated methods and computer program products. The irrigation controller may calculate a first estimated in-soil water level at a first point in time and a second estimated in-soil water level at a second point in time with the second point in time comprising a beginning of an impermissible watering period for one watering zone. The irrigation controller may set a watering schedule, based on an estimated irrigation rate and the difference between the second estimated in-soil water level and an in-soil water capacity, for the one watering zone of a property such that the second estimated in-soil water level is elevated to the estimated in-soil water capacity based on the estimated irrigation rate for the one watering zone during a permissible watering period immediately before the impermissible watering period.

Abstract: An electronic device is described, including memory and a processor coupled to the memory. The processor is configured to receive center pivot irrigation system information corresponding to a center pivot irrigation system and to request map data. The processor is also configured to a user interface with a map of the center pivot irrigation system. The processor is further configured to receive an input via the user interface indicating an input point. The processor is additionally configured to render an alteration point marker at a first position, the alteration point marker representing an alteration point for the pivot, the alteration point corresponding to a first radial position of the pivot at which a change in operation of the pivot is set to occur. The processor is also configured to control the center pivot irrigation system to alter operation of the pivot at the first radial position.

Abstract: A bracket assembly is described. A center bracket may have two protrusions on a first leg portion and two protrusions on a second leg portion. The protrusions of the center bracket may be positioned and shaped to interface with arcuate guide slots on leg portions of a first bracket and a second bracket. Curvatures of the arcuate guide slots may be positioned and shaped to maintain the center bracket longitudinal axis at substantially the same angle with respect to the first bracket longitudinal axis as the center bracket longitudinal axis is with respect to the second bracket longitudinal axis as the first bracket and second bracket pivot over a range of angles about a point of rotation in an assembled configuration.

Abstract: An irrigation sprinkler is described. The irrigation sprinkler includes a first ring including a first edge defining a first plurality of semicircular recesses and a second ring including a second edge defining a second plurality of semicircular recesses. The first ring and the second ring are secured together to define a plurality of circular recesses. The first ring includes a fin proximate each circular recess. The irrigation sprinkler also includes an adjustment mechanism disposed within each of the circular recesses. Each adjustment mechanism includes an outer rotating member including an annular structure comprising at least one of an annular recess and an annular protrusion, and an internal chamber including inwardly disposed threads. Each adjustment mechanism also includes an inner cylindrical member including an outer surface. The outer surface defines outwardly disposed threads and a channel. The channel extends radially along only a portion of the inner cylindrical member.
