Abstract: A multi-mode sprinkler adjustable for part or full circle operation to irrigate a selected area is provided. The sprinkler includes a nozzle for dispensing fluid, a set of gears for rotating the nozzle, and an arc setting mechanism that cooperates with the set of gears. The arc setting mechanism comprises a fixed trip for switching to a first direction for the nozzle and an adjustable trip movable relative to the fixed trip for setting an arc of rotation for the nozzle in the part circle mode. The arc setting mechanism also includes a toggle for engaging the fixed trip and the adjustable trip to switch between a first direction and a second direction when in the part circle mode. In the full circle mode, the adjustable trip is deflected radially outward, and the fixed trip deflects radially outward as it passes the toggle, allowing continuous rotation of the nozzle.

Abstract: An irrigation device is provided with an indicator that may be converted to indicate a condition, such as use with non-potable fluid. The irrigation device includes an inlet, and outlet, and a body defining a flow path from the inlet to the outlet. It further includes a cover with a removable section, and an indicator at least partially under the removable cover. The indicia indicate a condition of the irrigation device, such as being used with non-potable fluid. In one state, the cover is intact and the indicia are not exposed. In another state, the removable section has been removed and the indicia are at least partially exposed.

Abstract: An active liftgate spoiler used on a liftgate of a vehicle. The liftgate has an upper surface and is typically a rear liftgate or hatch on the rear side of the vehicle. A housing is connected to the upper surface of the liftgate. There is a moveable panel connected to the housing using a connection. The connection is formed by a four bar linkage that forms a portion of the connection between the moveable panel and the housing. An actuator, which in one embodiment is a single rotary actuator is connected to the four bar linkage and causes the movement of the moveable panel.

Abstract: There is provided a filter for a diaphragm valve. The filter attaches to a diaphragm of the valve and filters fluid entering a control chamber in the valve. The filter includes internal structure that increases the path from where fluid enters the filter through a mesh of holes to a single exit flow path leading to the control chamber. This increased path reduces the potential for debris in the flow to clog the exit flow path from the filter.

Abstract: There is provided a turf cup assembly that attaches to a buried pop-up type sprinkler to blend a top of sprinkler both cosmetically and functionally with turf surrounding the sprinkler. The turf cup assembly includes a turf cup and a sleeve. The turf cup mounts to a riser of the pop-up type sprinkler. The turf cup contains soil and root structure of turf. The sleeve surrounds the turf cup and attaches to a top of a housing of a pop-up sprinkler. The sleeve can be at or slightly below grade, and the cup extends out of the sleeve during an irrigation cycle and retracts into the sleeve at the end of the irrigation cycle.

Abstract: An active liftgate spoiler (10;100;200;300;400) used on a liftgate (8) of a vehicle (6). The liftgate has an upper surface (4) and is typically a rear liftgate or hatch on the rear side of the vehicle. A housing (11;104;202;302;412) is connected to the upper surface of the liftgate. There is a moveable panel (12; 102;204, 208; 306, 308;402,403) connected to the housing using a connection. The connection is formed by a four bar linkage (20,20?; 106, 106?;210,210?; 311,311?;411, 411?) that forms a portion of the connection between the moveable panel and the housing. An actuator (14;110;212;314;414), which in one embodiment is a single rotary actuator is connected to the four bar linkage and causes the movement of the moveable panel.

Abstract: Some embodiments provide irrigation generator systems that include a main conduit comprising an inlet conduit and an outlet conduit; a flow control system positioned within the main conduit; a generator conduit comprising a generator inlet conduit and a generator outlet conduit, wherein the generator inlet conduit is fluidly coupled with the main conduit upstream of the flow control system, the generator outlet conduit is fluidly coupled with the main conduit downstream of the flow control system; and a generator comprising a rotor assembly cooperated with generator conduit to be physically activated by a flow of fluid through the generator conduit causing rotation of the rotor assembly and generates electrical power. The flow control system transitions between a closed state to the open state in response to a water pressure exceeding a pressure threshold.

Abstract: An active aero panel assembly including at least one deployable panel, at least one drive mechanism, and at least one actuator. The active aero panel assembly improves aerodynamics.

Abstract: A pressure regulation device and method are provided for reducing fluid flow. The device may be disposed within a stem of a sprinkler, within the nozzle filter or other appropriate location within the sprinkler. The device may be a single piece structure that is formed from a thermoplastic elastomer material. The device has a body with slots that form sidewalls, which are configured to move relative to each other and deflect relative to a neutral state. The amount of movement relative to each other from the neutral state causes a reduction in pressure of the fluid exiting the regulator.
