摘要： Systems and methods are provided to transmit a data encoded power signal to addressable devices. A lighting controller sends the data encoded power waveform to a plurality of addressable lighting modules to power and control illumination intensity of lighting. The lighting modules are configured to receive the data encoded power signal via a two-wire communication network, decode illumination intensity data from the data encoded power signal, and generate a PWM signal responsive to the decoded illumination intensity data. The lighting modules use the data encoded power signal as a time base to synchronize the PWM signal to the data encoded power signal to reduce flickering when applying the PWM signal to control the illumination intensity of LEDs associated with the lighting modules.

摘要： Systems and methods are provided to transmit a data encoded power signal to addressable devices. A lighting controller sends the data encoded power waveform to a plurality of addressable lighting modules to power and control a behavior of the lighting modules. An inventory function causes the lighting controller to send, one by one, each of the possible unique addresses, or for a particular range of addresses, a command to turn ON lighting modules. The lighting controller monitors the current draw of the power supply or the data encoded power waveform and compares the monitored current with a threshold to determine whether the addressed lighting module responded to the command. The lighting controller provides the user, via a user interface, a list of the responding lighting modules based on the comparison.

摘要： An irrigation sprinkler can be provided with a flow guard feature configured to send an indicator stream into the air when a nozzle is missing, while still conserving most of the water that would have been wasted without the flow guard feature. The flow guard feature can include a valve assembly having a first port and a second off-axis port. The second port can be smaller than the first port. The second port can be non-parallel to the first port. The first port can be open when the nozzle is present and be sealed when the nozzle is missing. The second, off-axis port can be open even when the nozzle is missing to provide the indicator stream.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： An irrigation system comprises an irrigation 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.
