Abstract: The present invention provides a system and method for monitoring conditions within an electrical distribution system. According to a first preferred embodiment, the present invention provides a sensor module delivery system which uses UAVs to deploy sensor modules within the electrical distribution system. According to a first preferred embodiment, the system includes a drone mounting system and a gripper mechanism for attaching to a sensor module. The system also includes an extended carbon fiber shaft which vertically extends down from the drone mounting system and which supports a controller module, a transceiver, a battery module, a camera and the gripper mechanism. According to a further preferred embodiment, the gripper mechanism includes two or more gripping arms which are movable by the controller module between a first open position and a second closed position.

Abstract: A sprinkler has a housing with an inlet portion and an outlet portion in which a first outlet aperture is formed. The first outlet aperture may cooperate with other outlet apertures to define a spiral shape. A cam is disposed upstream of the first outlet aperture. The cam is rotatable about a cam axis to cover varying portions of the outlet apertures. After moving through the outlet apertures, water strikes a deflector and is sprayed outward from the head. The orientation of the cam establishes an arc angle through which water is sprayed, including a full-circle spray pattern. The deflector may be stationary or rotatable. In one alternative configuration, the outlet apertures and each leads to a different strip nozzle. The cam has an open portion that can be rotated into alignment with each of the outlet apertures to determine which of the strip nozzles are active.

Abstract: A valve containment assembly for an irrigation system may have a first side wall unit, a grate, a second side wall unit, and a lid. The first side wall unit may be disposed on the floor of a hole. The grate may be positioned in the first side wall unit to support a manifold. The second side wall unit rests on the first side wall unit to cover the manifold and the lid may be disposed on top of the side wall unit. The first side wall unit and the grate elevate the manifold above the floor of the hole to reduce interference of soil and water with the manifold. Additional side wall units may be used to provide additional height. Any of the side wall units may have frangible portions that break away to permit passage of conduits into the valve containment assembly.
