Patent number: 8738189Abstract: The present invention provides methods for water conservation with irrigation controllers based upon the ambient temperature and extraterrestrial radiation of a particular geographical area. It receives a preliminary irrigation schedule from the operator and computes a water budget ratio by comparing current local geo-environmental data with stored local geo-environmental data, then modifying the preliminary irrigation schedule based upon that ratio. The present invention utilizes fewer variables, is less complex, and is much easier to install and maintain than the current evapotranspiration-based controllers.Type: GrantFiled: March 11, 2013Date of Patent: May 27, 2014Inventor: George Alexanian

The irrigation controller further includes circuitry that enables a communication link that allows direct communication between the first processor and a sensor unit containing a second processor and a plurality of environmental sensors each capable of generating an actual component of ET data. At least one manually actuable control is operably connected to the first processor for inputting further ET-related information selected from the group consisting of plant type, soil condition, growth stage and sprinkler precipitation rate. The irrigation controller further includes programming that enables the first processor to calculate optimum watering schedules based upon the actual ET data and the ET-related information including increases and decreases in the frequency and/or length of ON times for at least one station.Type: GrantFiled: January 21, 2011Date of Patent: October 1, 2013Assignee: Hunter Industries, Inc.Inventors: La Monte D. Porter, Peter J. Woytowitz, Christopher M. Shearin

Publication number: 20130253713Abstract: Irrigation control systems and method of operating an irrigation system are described for irrigation systems including one or more orifices, e.g., sprinkler heads, arranged in one or more irrigation lines. The control system can include one or more sensors such as moisture meters and flow meters that measure water output associate with the irrigation system. The irrigation control system can be linked to one or more networks for access, e.g., through the Internet. The control systems and methods can utilize moisture calibration to avoid or reduce a need for continuous use of moisture sensors.Type: ApplicationFiled: March 12, 2013Publication date: September 26, 2013Applicant: LSI Saco Technologies, Inc.Inventors: Mark VanWagoner, Tim Frodsham, Joseph E.

Publication number: 20130253714Abstract: An irrigation controller includes a housing for enclosing a microprocessor that stores and executes at least one watering program. The microprocessor has a parallel output bus with a plurality of pin sets for controlling a plurality of irrigation stations. The connection between the controller and the irrigation stations is through a plurality of station modules that are removably coupled, in any desired number, to the various pin sets on the output bus. The number of stations controlled is adjusted by the number of modules connected to the output bus. The controller housing has a pocket for holding a user's manual, which is positioned between the controller housing and a mounting bracket. when the controller housing is installed on the mounting bracket.Type: ApplicationFiled: May 20, 2013Publication date: September 26, 2013Applicant: The Toro CompanyInventors: Jonathan D. Williams, Peter M.F. Tam

Publication number: 20130253712Abstract: The present invention provides methods for water conservation with irrigation controllers based upon the ambient temperature and extraterrestrial radiation of a particular geographical area. It receives a preliminary irrigation schedule from the operator and computes a water budget ratio by comparing current local geo-environmental data with stored local geo-environmental data, then modifying the preliminary irrigation schedule based upon that ratio. The present invention utilizes fewer variables, is less complex, and is much easier to install and maintain than the current evapotranspiration-based controllers.Type: ApplicationFiled: March 11, 2013Publication date: September 26, 2013Inventor: George Alexanian

Patent number: 8538592Abstract: Embodiments of the present invention provide methods and apparatus for water conservation with landscape irrigation controllers, plug-in and add-on devices, and centralized systems. In embodiments of the invention, a water budget percentage is determined by comparing current local geo-environmental data with stored local geo-environmental data, and the preliminary irrigation schedule or station run times are automatically modified based upon that water budget percentage. Embodiments of the present invention also provide for automation of mandated landscape watering restrictions alone, or in various combinations with water budgeting methods and apparatus.Type: GrantFiled: October 18, 2011Date of Patent: September 17, 2013Inventor: George Alexanian

Patent number: 8532831Abstract: An irrigation control device having a modulator that modulates data onto an alternating power signal by distorting amplitude of a first leading portion of selected cycles of the alternating power signal, and permit effectively a full amplitude of the alternating power signal on a following portion of the selected cycles, wherein the first leading portion and the following portion are either both on a high side of a cycle or both on a low side of a cycle of the alternating power signal. The irrigation control device further includes an interface configured to couple the modulator to a multi-wire interface coupled to a plurality of irrigation devices to permit the alternating power signal to be applied to the multi-wire interface.Type: GrantFiled: August 8, 2012Date of Patent: September 10, 2013Assignee: Rain Bird CorporationInventor: Timothy J.

Publication number: 20130226356Abstract: The method determines an actual position of the end tower while the irrigation system is in operation; determines an actual angular orientation of the extension arm relative to the end tower; accesses memory and determines the desired angular orientation of the extension arm; and compares the actual angular orientation to the desired angular orientation. If the actual angular orientation deviates from the desired angular orientation by more than a threshold amount, the method shuts down the irrigation system.Type: ApplicationFiled: February 29, 2012Publication date: August 29, 2013Applicant: Lindsay CorporationInventors: Jochen Pfrenger, Mark William Miller, John Grabow, Christopher Thomas Lawson

Publication number: 20130211604Abstract: An electronic control unit for programmed watering of lawns, gardens, flower boxes and similar spaces, comprises a front panel, a display, watering program selection push-buttons for selecting the watering duration and the watering repetition frequency and at least one start push-button for starting the selected program. The control unit comprises an electronic micro controller which, in response to the operation of said selection push-buttons, controls the visualization of the duration and frequency of the selected program and, in response to a single operation of the start push-button, controls the immediate start of the selected watering program. If the start push-button is operated for a variable number of times, the micro controller programs the delayed start of the selected program.Type: ApplicationFiled: February 14, 2013Publication date: August 15, 2013Applicant: CLABER S.P.A.Inventor: Claber S.p.A.
