Patent number: 8924031Abstract: Irrigation of plants or crops is effected using plant canopy temperature measurements. The process and device include an irrigation scheduling algorithm based on an integrated water stress index (WSI) and an integrated WSI set-point. A WSI is calculated at repeated time intervals and compared to an encoded threshold WSI value that is crop and region specific. If the calculated WSI is greater than the encoded WSI value, a unit of integrated WSI (IWSI) is accumulated. If the time integral exceeds the encoded value for a 24 hour period, an irrigation signal is produced, directing the irrigation system where, when and how much to irrigate. The process and device will automatically schedule crop irrigations when the crop is water stressed and may control a moving or static irrigation system to apply the irrigation. Moreover, irrigation applications can be selectively varied over specified control areas or management zones.Type: GrantFiled: February 23, 2012Date of Patent: December 30, 2014Assignee: The United States of America, as represented by the Secretary of AgricultureInventors: Steven R.

A plurality of switches are operatively connected to the processor for turning a power signal ON and OFF to a plurality of valves that deliver water to a plurality of sprinklers in different zones. Programming is stored in the memory for implementing a seasonal adjustment feature that is independently operable with a plurality of individual watering programs to selectively energize the valves. The programming calculates a soil moisture requirement value for each program using a signal from at least one soil moisture sensor that is associated with a zone that is assigned to that watering program, and automatically modifies the watering program assigned to that zone through the seasonal adjust feature based on the soil moisture requirement value.Type: GrantFiled: February 25, 2010Date of Patent: July 29, 2014Assignee: Hunter Industries, Inc.Inventors: Peter J.

Patent number: 8793025Abstract: Control devices for use in decoder-based irrigation control systems, and related methods, are provided herein. In one implementation, an irrigation control device comprises decoder circuitry located within a first housing and having an electrical connection configured to couple the decoder circuitry to a control wire path of a decoder-based irrigation control system; a coil located within a second housing; a first wire electrically coupling the decoder circuitry to a first connection of the coil; and a second wire electrically coupling the decoder circuitry to a second connection of the coil. The coil is configured to develop an electromagnetic flux sufficient to cause actuation of a device controlling irrigation equipment in response to signaling from the decoder circuitry. The first housing, the second housing, the first wire and the second wire are non-separably and functionally connected together.Type: GrantFiled: December 20, 2011Date of Patent: July 29, 2014Assignee: Rain Bird CorporationInventor: Michael A.

Publication number: 20140195059Abstract: An irrigation controller, includes a housing, a microcontroller within the housing and configured to store and execute an irrigation schedule, a valve driver coupled to the microcontroller and configured to output a zone activation signal to an actuatable zone valve in response to signaling from the microcontroller, and a user interface. The user interface includes a plurality of user input devices coupled to the microcontroller and configured to provide signaling to the microcontroller based upon a user's engagement therewith, the plurality of user input devices configured to allow the user to create an irrigation schedule; and a user display coupled to the microcontroller and configured to display irrigation parameters associated with the irrigation schedule. The microcontroller is configured to cause the user display to display at least one of a next irrigation start day, a next irrigation start time, and a next zone to irrigate associated with the irrigation schedule.Type: ApplicationFiled: March 12, 2014Publication date: July 10, 2014Applicant: Rain Bird CorporationInventor: Steven W.

Patent number: 8751052Abstract: A method and system for monitoring the dynamic response of soil moisture and setting a threshold in relation to the field capacity of a soil area is disclosed herein. By measuring the dynamic response of soil moisture under wet soil conditions, one can determine a practical field capacity for the soil, in-situ, based solely on the soil moisture sensor output. Essentially, by looking at how the soil moisture level varies with time one can determine the field capacity.Type: GrantFiled: January 31, 2011Date of Patent: June 10, 2014Assignee: Green Badge, LLCInventors: Jeffrey Campbell, Kathy Sohrabi, Clayton R.

Publication number: 20140148959Abstract: A sprinkler system is controlled to ensure that a given geographic area receives sufficient watering without being over-watered. The sprinkler system, capable of being programmed to deliver a desired amount of water in accordance with a desired daily watering schedule, is programmed to deliver the desired amount of water every day unless interrupted. Rainfall information is received, and a signal is sent to interrupt the sprinkler system, causing the sprinkler system to: a) follow a predetermined watering schedule when there is no rain, in which case the sprinkler system delivers the desired amount of water following a predetermined number of days, n, without watering, or b) increase n by 1 or more days if the rainfall information indicates at least one significant rain event capable of providing the desired amount of water, and c) return to a) when n expires.Type: ApplicationFiled: August 14, 2013Publication date: May 29, 2014Inventors: Michael R.
