  • Patent number: 7711454
    Abstract: An irrigation controller has run-times that are modified as a function of a calculated volumetric irrigation amount and a preferred irrigation amount. The preferred irrigation amount is at least partly based on an evapotranspiration (ETo) value and the area of the irrigated site. The calculated volumetric irrigation amount is based on flow meter data and inputted irrigation run-times. Preferably the flow meter is a water meter that measures water distributed to the irrigation system and to other water using devices at the irrigated site, and the flow data is based on signature data. In addition to flow data, water pressure may be measured that corresponds with the flow data. It is anticipated that the function will involve the dividing of the preferred irrigation amount by the calculated volumetric irrigation amount to arrive at a modifying factor.

  • Publication number: 20100106337
    Abstract: A method of controlling the duration of irrigation is described, comprising compiling a database that includes information relating to historical evapo-transpiration rates for a plurality of sectors (preferably identified by zip code) located within a geographical area. Period Reduction Factors for each sector are derived. Parameters are entered into the controller including a Maximum Irrigation Duration, a sector identifier; and the current date. The Maximum Irrigation Duration is adjusted by multiplying the Maximum Irrigation Duration by a Period Reduction Factor for the current period associated with the sector that has been identified by the user, to obtain an Actual Irrigation Duration. The irrigation system is caused to irrigate for the Actual Irrigation Duration during the current period.

    Abstract: The present invention is directed to an intelligent water management irrigation system for monitoring the total water usage for a billing site and preventing cumulative water usage from exceeding a water budget by adjusting the amount of water used for irrigation. Irrigation zone priority values are selected for each irrigation zone that specify a percentage of the full water need that the foliage in the zone can survive and are saved in an intelligent water management irrigation (IWMI) controller. The IWMI controller receives water usage information originating from a property's water meter and compares the measured water usage with the allowable water budget. Water usage is tracked separately for the household use and landscape use (irrigation). Prior to each irrigation cycle, the IWMI controller estimates the amount of water that will be needed by the landscape and for household use during the remainder of a billing cycle; household use is given precedence over landscape use.

    Abstract: A system for optimizing the power to a movable valve core includes a controller for providing a control signal to the core, which is movable between first and second positions. With the core in the first position, the control signal has a hold voltage, and the controller measures a first self inductance. The control signal is provided with an inrush voltage for forcing the core from the first position to the second position, and then with the hold voltage for retaining the core in the second position. With the core in the second position, the controller measures a second self inductance, and it gradually decreases the hold voltage and measures a third self inductance representing the actual position of the core. The controller determines, by comparing one of the first and second self inductances with the third self inductance, whether the core is in the first or second position.

  • Publication number: 20090216345
    Abstract: A node of a fault-tolerant system relies upon a primary communication mechanism, when possible, for primary connection to a central server. The node monitors its primary connection to the server. While the primary connection is active, the node operates in a supervised mode, in that it generally does not perform a certain subset of tasks without having received real-time commands from the server to perform those tasks. However, when the node detects that it is no longer connected to the server, the node transitions into a fail-over mode. The node operates in the fail-over mode until the node detects that primary connection is re-established. While in fail-over mode, the node may execute a stored set of fail-over instructions that were provided by the server. The node may also attempt to establish a backup connection to the server via a second and different type of communication mechanism.

  • Patent number: 7574284
    Abstract: A self-adjusting irrigation controller takes a pre-irrigation soil moisture reading prior to irrigation, chooses an amount of water to be dispensed corresponding to that reading from a table, and dispenses that amount of water. A predetermined length of time after the end of irrigation, the controller takes a post-irrigation soil moisture reading and compares the value of that reading to a predetermined target value. If the post-irrigation value differs substantially from the target value, the water amount corresponding to the pre-irrigation value in the table is adjusted to reduce that difference on the next scheduled irrigation cycle having that same pre-irrigation soil moisture reading. The target value is determined by watering the soil to field capacity, then computing the target value as a function of the reading of the sensor at field capacity. The controller thus converges toward an ideal runtime and follows changes in the environment.

  • Patent number: 7558650
    Abstract: Several embodiments provide wireless extensions to an irrigation controller system and related methods of use, as well as other improvements to irrigation control equipment. In one implementation, an irrigation control system includes a transmitter unit including a controller and having a connector to be coupled to an irrigation controller having station actuation output connectors. The controller is configured to receive an indication that the irrigation controller has activated an irrigation station, and is also configured to cause the transmitter unit to transmit a wireless activation signal responsive to the indication. A receiver unit is coupled to an actuator coupled to an actuatable device, such as an irrigation valve, the actuator configured to actuate the irrigation valve to control the flow of water therethrough. The receiver unit receives the wireless activation signal and in response, causes the actuator to actuate the actuatable device.
