A pre-calibrated spray plane image acquisition device is described that includes, in a single fixed-form structure, both an image capture component configured to acquire an optical image of a field of view and a light plane generator configured to generate a planar light plane emitted from the pre-calibrated spray plane image acquisition device. A carrier frame structure includes rigid components for permanently maintaining the image capture component and the light plane generator in respective positions defining a permanent spatial relationship between the field of view of the image capture component and the light plane generated by the light plane generator.

A weed spot-spraying system is described for carrying out a spot-based weed spraying method based upon a classification value rendered from a sub-field image in accordance with a machine learning-based trained model applied by a processor to the sub-field image. The system includes a camera; a spray nozzle assembly including a spray nozzle; and a processor. The method carried out by the system includes acquiring, by the camera, a full field of view image of a crop floor. The method further includes extracting, from the full field of view image, a sub-field image corresponding to the spray nozzle positioned to provide a spray field extending over a part of the crop floor depicted in the sub-field image; rendering, by the processor in accordance with the machine learning-based trained model, a classification for the sub-field image; and selectively activating the spray nozzle in accordance with the classification for the sub-field image.

A liquid spray boom for supporting a plurality of spray nozzle assemblies each having a compact design that enables transfer and storage of the spray boom with lesser tendency for damage. The spray nozzle assemblies each include a liquid inlet section and a pair of spray nozzle liquid supply and support legs extending from the liquid inlet section in forward transverse relation to the spray boom and at an acute angle to each other. A spray nozzle is removably mounted on each nozzle body liquid supply leg with a respective check valve disposed in rearward relation to the spray nozzle. The liquid inlet section, Y body, and supporting components for the spray nozzles and check valve are adapted for quick disconnect assembly and disassembly.

A spray header assembly includes a spray header pipe with an elongated tubular side wall with a hollow interior that defines an internal fluid passageway. The spray header pipe includes a plurality of spray nozzle ports. Each spray nozzle port including a respective mounting opening that extends through the side wall of the spray header pipe and communicates with the internal fluid passageway. Each spray nozzle port including a respective annular extension that extends radially inwardly from an inner surface of the side wall into the internal fluid passageway. Each annular extension extends seamlessly from the header pipe and is formed unitarily from the material of the header pipe. A respective spray nozzle secured in each mounting opening.

An electrostatic spray nozzle assembly is described that includes an induction ring and a fluid tip. The induction ring generates an electrical field for inducing an electrical charge on droplets of a feedstock liquid from the fluid tip that pass through an opening of the induction ring. The induction ring is electrically coupled to an electrical induction field source via a first conductive path comprising at least an electrically conductive pliable structure, such as a stainless steel spring. Feedstock flowing through the fluid tip is electrically coupled to a charge carrier source via a second conductive path provided by at least a conductive surface of a fluid tube coupled to the fluid tip. The first conductive path and the second conductive path are electrically isolated by an insulating barrier.

A liquid spraying system having a liquid spray section and a controller for controlling liquid to the spray section. The controller includes a valve operable between multiple positions for controlling the supply of liquid to the spray section and enabling the flow of liquid from the spray section to a flow back line only after the liquid supply to the spray section has been terminated.

A spray nozzle assembly includes a nozzle body supporting a plurality of spray nozzles. The plurality of spray nozzles are divided into a plurality of different stages. The nozzle body includes a first fluid distribution passage that communicates with a first spray nozzle stage and a second fluid distribution passage that communicates with a second spray nozzle stage. A nozzle inlet includes a plurality of fluid inlets including a first fluid inlet that communicates with the first fluid distribution passage of the nozzle body and a second fluid inlet that communicates with the second fluid distribution passage of the nozzle body. Control of fluid flow through the first fluid distribution passage to the first spray nozzle stage and through the second fluid distribution passage to the second spray nozzle stage adjusts a total spray volume or a flow rate of the spray nozzle assembly.

A modular liquid distribution system in which each module has a module body, a spray nozzle, and a piston for controlling the dispensing of liquid from the nozzle. Each module has a pneumatically operated system for moving the piston to an open position while facilitating quicker return movement to a closed position, enabling the dispensing of precisely controlled small droplet sized quantities of highly viscous liquids.

A system is described for producing solutions from respective outputs of an electrolytic cell. The system includes a reverse osmosis (RO) unit comprising a membrane for purifying water, and producing as output: an RO effluent, and an RO water product. An electrochemical activation system (ECAS) is provided that includes the electrolytic cell configured to: receive a catholyte input flow on a cathode cell side to produce a catholyte cleaning fluid, and receive an anolyte input flow on an anode cell side to produce an anolyte disinfecting fluid. At least one of the catholyte input flow and/or the anolyte input flow is provided from at least one of the RO effluent and/or the RO water product. At least one recirculation line and controllable valves are provided that are configured to controllably supply a recirculated fluid from output storage tanks to at least one input flow.
