Abstract: An irrigation controller comprises actuable controls, a memory to store the watering program, and one or more displays. The actuable controls and display are incorporated into a removable face pack that is mounted to an interior door of the irrigation controller. The face pack can be easily moved from a first position on the front side of the interior door to a second position on the back side of the interior door and the face pack automatically senses its position. When the face pack is in the first position, the actuable controls and display are configured for operating information. When the face pack is in the second position, the wiring hook up area of the irrigation controller is exposed and the actuable controls and display are configured for diagnostics.

Abstract: A watertight electrical compartment for use in an irrigation device can include a compartment body having a chamber and a sealing section configured to mate with one or more sealing rings. A sealing cap can 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. One of the compartment body and cap retainer can have internal threads to be screwed onto external threads of the other one of the compartment body and cap retainer. 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 lighting system includes lighting fixtures and a lighting controller that sends commands and data over an AC power line to power and control the lighting fixtures. Lighting themes are uniquely programmable color and intensity that are applied to a collection of lighting groups to achieve different lighting modes instantly, without the delay that programming each lighting fixture individually incurs. The groups of lighting modules receive theme lighting information over the power line and store the theme information in memory. The lighting controller sends a single command to the collections of the lighting groups to apply the theme. Each lighting module retrieves and applies the theme information.

Abstract: An irrigation control box can include a housing base having a first sidewall, a second sidewall, a top sidewall, a bottom sidewall, and a back wall. The box can include at least one hinge post. An offset hinge assembly can include a hinge assembly frame defining a hinge assembly interior, a first attachment structure positioned at least partially within the hinge assembly interior and configured to releasably attach to the at least one hinge post, and a rotational attachment point. A facepack can include at least one hinge point configured to mate with the rotational attachment point. In some cases, the facepack is configured to rotate about rotational attachment point of the offset hinge assembly with respect to the housing base when the housing base and facepack are each attached to the offset hinge assembly.

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: Systems and methods to authenticate a controller having a user interface with a manually actionable control include randomly selecting a first position of the plurality of positions of the manually actuatable control, prompting a user to position the manually actionable control to the randomly selected position, receiving an indication of the present position of the manually actionable control, comparing the indication of the randomly selected position with the indication of the present position, and authenticating the controller when the indication of the randomly selected position matches the indication of the present position.

Abstract: Systems and methods are provided to transmit a data encoded power signal to addressable devices. A data signal includes address and command data that varies between logical states. A controller provides a low loss rectified power signal. The controller further provides data within the power signal by forming a positive polarity rectified power waveform corresponding to data in a first state and a negative polarity rectified waveform signal corresponding to data in a second state using substantially loss-less circuitry.

Abstract: A sprinkler can include a turbine, a nozzle, a gear drive and a reversing mechanism. The gear drive and the reversing mechanism rotatably couple the turbine and the nozzle. The gear drive can shift a direction of rotation of an output stage that is coupled to the reversing mechanism. The sprinkler can include at least one arc adjusting gear that moves and arc adjusting tab to contact a shift arm to cause the shifting mechanism to change direction. The arc adjusting gear can engage with the arc tab for adjusting the arc setting and disengage from the arc tab for normal operation.

Abstract: A light fixture can include a light housing and a light cartridge. The light cartridge can be configured to releasably and/or electrically connect to a portion of the light housing. In some embodiments, the light cartridge includes a collar movably connected to the cartridge and configured to rotate with respect to the cartridge. Rotation of the collar can facilitate attachment and/or release of the cartridge from the light housing. In some cases, the cartridge includes a releasable driver, one or more lenses, one or more beam reflectors, one or more diffusers, and/or other electrical and optical components.

Abstract: An irrigation system comprises an Internet connected controller that receives user input and provides a power signal and command and message data to an encoder. The encoder encodes the command and message data onto the power signal to provide a data encoded power waveform that is sent over a two-wire path. The irrigation system further comprises one or more decoders in communication with the two-wire path to receive the data encoded power waveform and one or more irrigation valves in communication with the one or more decoders. The data encoded power waveform provides power to the decoders and the decoders decode the command and message data from the data encoded power waveform to control the irrigation valves according to the user input. Thus, a user controls an irrigation system comprising the two-wire path from a remote location using an Internet-compatible device without specific software installed.

Abstract: A control module for a water harvesting system can be operatively connected to a water level sensor in a water collection cistern, the pump/master valve (P/MV) output port of an irrigation controller, a pump start relay that controls a pump coupled to the cistern, and a pair of master valves that are coupled to station valves for delivering water to a plurality of sprinklers. The control module uses a processor, a plurality of switching circuits, and an operational program stored in a memory to cause the landscape vegetation to be watered with water from the water collection cistern or a municipal water supply, depending on the level of water detected in the water collection cistern. The control module can include a display that can indicate a graphic depiction that represents an actual level of the water in the water collection cistern.
