Abstract: A radially adjustable landscape light fixture mount includes a mounting plate having a female threaded portion for affixing a light fixture thereto and a separate mounting stake having a locking lever. The mounting stake has a recessed portion for receiving the mounting plate and affixed light fixture. The locking lever has an open position and a closed position. When the locking lever is in the open position the radial position of the mounting plate and affixed light fixture can be adjusted relative to the mounting stake by a user. In the closed position the locking lever fixes the radial position of the mounting plate.

The removable components can include one or more removable communications module configured to facilitate communication between the interface system and one or more other communications or control systems. A facepack can be removably coupled with the housing. The facepack can include one or more displays and/or user input structures.

Abstract: An illuminating device can include a housing having one or more sidewalls defining a housing interior. The device can include at least one light element and an optics assembly. The optics assembly can include an outer face and at least one lens. The at least one lens can be configured to allow light from the at least one light element to pass therethrough. The optics assembly can include a skirt extending from the outer face into the housing interior and surrounding the at least one lens. The skirt can have an interior surface defining a skirt interior and an outer surface facing the one or more sidewalls of the housing. Potting material can be positioned between the outer surface of the skirt and the one or more sidewalls to prevent water ingress into the skirt interior. In some cases, no potting material is positioned within the skirt interior.

Abstract: A sprinkler can include a nozzle turret having a removable nozzle carrier. For example, the nozzle carrier can be removably installed within a recess of a nozzle housing. The nozzle carrier can include one or more nozzle ports configured to receive sprinkler nozzles. The nozzles can have varying characteristics including flow rate, output range, spray pattern, etc. In some cases, a primary nozzle can be removably coupled with the nozzle carrier. The primary nozzle can include a body (e.g., inlet) portion having a first axis and a tapered (e.g., outlet) portion having a second axis non-parallel to the first axis. The primary nozzle can be configured to be installed in the nozzle carrier in at least two orientations. In some cases, one or more secondary nozzles are removably or permanently connected to the nozzle carrier.

Abstract: A drive circuit for a DC latching device includes a battery, a storage element, and a plurality of switches connecting the battery to the storage element for charging the storage element from the battery and discharging the storage element into the coil of a DC latching device. The drive circuit further includes components for determining a state of the DC latching device. The drive circuit may include components for terminating the discharge of the storage element into the coil of the DC latching device in response to determining that the DC latching device has changed states to add reliability to the system and reduce energy consumption.

Abstract: A watertight electrical compartment for use in an irrigation device can include a compartment body with a chamber, a sealing section mounted with one or more sealing rings, and external threads. A sealing cap mate with the sealing section and/or the sealing rings to seal the chamber. A cap retainer can be advanced over at least a portion of the sealing cap and can have internal threads to be screwed onto the external threads of the compartment body. The cap retainer can also have a stopping feature to keep the sealing cap in its sealed position. The watertight electrical compartment can be used in a wireless flow sensor assembly, a battery operated irrigation controller, and/or a battery-operated central controller device, to provide irrigation control, and/or sensor information, without the need for AC power.

Abstract: A drip emitter for subsurface irrigation includes a valve chamber defining a hollow interior, an entry port and at least one exit port. A flexible diaphragm is mounted in the hollow interior of the valve chamber for movement in response to pressurized water being supplied to the hollow interior through the entry port. The drip emitter further includes a tortuous path water flow channel that limits the flow of water from the hollow interior of the valve chamber to the at least one exit port. A closure member is moved by the flexible diaphragm to open the at least one exit port when pressurized water enters the hollow interior to allow water to be discharged through the at least one exit port. A spring moves the closure member to close the at least one exit port when the supply of pressurized water is shut OFF.

Abstract: A modular irrigation controller has a robust ground path with high conductivity that can accommodate lightning induced power surges on field valve wires and common wires that are connected to a plurality of station modules. Sensitive electronic components in the station modules are thereby protected from damage. The robust ground path extends from conductors on circuit boards within the station modules through captive mounting screws to a metallic backplane and then through metallic grounding brackets within a pedestal enclosing the modules and the backplane. The grounding brackets are in turn grounded to both an earth ground stake and to a ground wire associated with the incoming one hundred and ten volt AC power.

Abstract: A sprinkler nozzle includes a nozzle plate having at least one orifice formed therein. A stream deflector is rotatably mounted adjacent the nozzle plate and has a plurality of flutes formed therein that face the nozzle plate. Each flute has an inner portion that can momentarily align with water flowing through the orifice in the nozzle plate during rotation of the stream deflector relative to the nozzle plate. Water flowing through the orifice will be channeled in a generally radial direction by the flute to form a stream of water that is ejected from the stream deflector. The flutes have a plurality of different tangential trajectories relative to the orifice in the nozzle plate so that in combination the streams of water successively ejected from the stream deflector establish a predetermined shape of coverage.

Abstract: The disclosure includes various embodiments of an irrigation mat. In some embodiments, the mat is generally installed so that plants meet the layer of moisture formed by a nonwoven textile web in a relatively short time due to growth of roots. Some embodiments include a web where the roots of plants can grow into the web and thus those plants can be supplied with moisture.

Abstract: An irrigation system includes at least one environmental sensor, such as a solar radiation sensor that is installed on an irrigation site, and a soil moisture sensor that is also installed on the irrigation site. Programming allows an estimated ET value to be calculated based at least in part on the output signal of the environmental sensor. A pre-programmed watering schedule is automatically modified based on the estimated ET value to thereby conserve water while maintaining the health of plants on the irrigation site. The system automatically inhibits irrigation when an output signal of the soil moisture sensor indicates an amount of moisture in the soil is above a predetermined threshold.
