The present invention provides a system, method and apparatus for providing variable rate application of applicants to discrete field locations. According to a first preferred embodiment, the present invention includes a control device having software modules to allow for the execution of irrigation and chemical spray patterns according to specific prescriptions for each crop being sprayed. According to further preferred embodiments, the control device may use data from a variety of image sensors to create a selective, variable rate application of applicants. Using the imaging data, the system of the present invention may use a primary applicant system to broadly deliver a first selected application (e.g. water or the like) and use a separate system to deliver targeted applicants for specific plants or areas of a given field.

The present invention provides a system and method for analyzing sensor data related to an irrigation system. According to a preferred embodiment, the system includes algorithms for analyzing real-time, near real-time and historical data acquired from sensors in communication with a mechanized irrigation machine. Further, the algorithms of the present invention system may analyze collected sensor data to determine if an event has occurred or is predicted to occur. Further, the algorithms of the present invention may provide commands to an irrigation machine and notifications to users. According to further aspects of the present invention, the algorithms of the present invention may preferably apply machine learning and other data analysis tools to detect maintenance patterns, geographic trends, environmental trends, and to provide predictive analysis for future events.

The present invention provides a fiber-optic communication system that allows high-bandwidth communications between components of an irrigation machine. In accordance with a preferred embodiment, the present invention teaches a system and method for providing a two-way communications link between a pivot controller panel and distributed irrigation machine components. According to further preferred embodiments, the two-way communications link of the present invention may also convert optical signals to electrical signals and route those signals to the appropriate connected devices.

System and method for transmitting data within an irrigation system

The present invention provides a system and method for maintaining desired pressure levels in an irrigation system when the flow rate available to the irrigation system is reduced below the system's required flow rate. According to a first preferred embodiment, the present invention teaches a method which includes the steps of: receiving and storing irrigation system information including sprinkler specifications, flow rates and pressure requirements; receiving and storing an irrigation plan to be executed including the target amount of an applicant to be applied to a target area; determining an available flow rate to the irrigation system; determining a required flow rate of the irrigation machine; comparing the available flow rate to the required flow rate to determine whether the available flow is sufficient for the system based on the sprinkler specifications; adjusting the pulse rate of the sprinklers to reduce the require flow rate to at least the available flow rate; and calculating and selecting a lower ground speed required to apply the target amount of applicant to the target area based on the selected pulse rate for the sprinklers.

The present invention provides a system and method which combines sensor inputs, control systems, field mapping, motor controls, and high speed and variable speed motor designs within an irrigation machine. According to a preferred embodiment, the present invention provides systems which are capable of full torque operation, even at speeds less than the rated speed of the motor. According to further preferred embodiments, the present invention utilizes a combination of motor types including Switch Reluctance, DC Permanent Magnet and AC Permanent Magnet motors in combination with Variable Frequency Drives.

An overhead irrigation assembly having multiple truss rods is disclosed. In an implementation, an overhead irrigation assembly includes a first support, a second support, and a span of pipeline supported between the first support and the second support. The overhead irrigation assembly also includes a first truss rod tensioned between the first support and the second support and a second truss rod tensioned between the first support and the second support. Spreaders are suspended from the span of pipeline that are configured to separate the first truss rod from the second truss rod. The overhead irrigation assembly also includes a third truss rod is also tensioned between the first support and the second support. The first truss rod, the second truss rod, and third truss rod are configured to maintain a generally bow shape in the span of pipeline.

A fuel air mixer for a gas turbine engine combustor having a longitudinal axis therethrough, wherein the fuel air mixer is configured for use in a dome oriented substantially radial to the longitudinal axis. The fuel air mixer includes a fuel injection assembly having a first end, a second end, a fuel passage extending therethrough, and a flange portion having a plurality of spaced openings formed therein which extends from the first end. The fuel air mixer also includes a mixer assembly having a first end, a second end, a cavity formed in a central portion thereof, and a flange portion having a plurality of spaced openings formed therein which extends from the first end. The mixer assembly is configured to receive the fuel injection assembly in the cavity so that the fuel injection assembly and the mixer assembly are able to be connected to an outer casing of the combustor by means of the respective flange portions.

A combustor dome assembly is provided with a single continuous annular dome plate having at least one circumferential row of spaced openings therethrough, a swirl cup assembly attached to each of the dome plate openings, and inner and outer cowls connected to the radially inner and outer ends of the dome plate. A ferrule located immediately upstream of the swirl cup assembly acts as an interface between a fuel nozzle and the swirl cup assembly. An integral cowl plate/ferrule retainer is located immediately upstream of and connected to the swirl cup assembly, where the ferrule retainer portion retains the ferrule while allowing it to float radially therewithin and the cowl plate portion includes flanges which extend beyond the outer diameter of the swirl cup to provide blockage in addition to that provided by the inner and outer cowls.
