A nozzle assembly, an evaporation plating apparatus, and a method of manufacturing an organic light emitting diode device is provided. A first heating element is arranged in the hollow cavity in the sidewall of the nozzle. When organic material is vapor deposited, the first heating element can perform heating to raise the temperature of the peripheral wall of the nozzle to be substantially the same as or slightly higher than the temperature of the evaporation plating chamber, thereby maintaining the temperature in the nozzle within a suitable range so that it is neither too low to cause the organic material to condense in the nozzle nor too high to carbonize the organic material.

A method for an agricultural application operation is provided herein. The method includes receiving a target application condition for an agricultural product to be exhausted from a nozzle assembly through an input device. The method also includes receiving an agricultural product flow condition and data related to boom movement from a sensing system. In addition, the method includes receiving a first duty cycle from a computing system. The method further includes determining a detected application condition based on the agricultural product flow condition, the data related to boom movement, and the first duty cycle with the computing system. Lastly, the method includes generating a duty cycle command based on a comparison of the target application condition to the detected application condition with the computing system.

Embodiments of a boom system for a work vehicle has a first boom member with a plurality of first boom segments aligned lengthwise to extend along a first boom dimension and a second boom member with a plurality of second boom segments aligned lengthwise to extend in the first boom dimension and spaced from the first boom member in a second boom dimension. The boom system also has a union spanning the second boom dimension to couple the first boom member to the second boom member and having a first coupling segment joining consecutive first boom sections together and a second coupling segment joining consecutive second boom sections together.

Embodiments are directed to a fluid-emission device. An example fluid-emission device includes a tubular body, a fluid-source coupler, and a tip member disposed opposite the tubular body from the fluid-source coupler. A fluid-transmission lumen in the tubular body fluidly couples the tip member to the fluid-source coupler. The tip member includes a plate having a plurality of fluid-emission lumens that fluidly couple the fluid-transmission lumen to an environment outside the tubular body. The tip member includes a spearhead disposed opposite the plate from the fluid-transmission lumen. The tip member has a spacer disposed between the plate and the spearhead to separate the spearhead from the fluid-emission lumens. The fluid-emission device can be used by inserting the tip member into material and delivering fluid to a target, such as delivering water or fertilizer to plant roots or the like.

A system for controlling nozzle flow rate includes a master node having an expected overall flow rate module configured to generate an expected overall flow rate of an agricultural product based on one or more sprayer characteristics, and an adjustment module configured to generate an error correction based on a difference between the expected overall flow rate and an actual overall flow rate of the agricultural product. A plurality of smart nozzles are in communication with the master node, each of the smart nozzles includes an electronic control unit in communication with one or more control valves and one or more nozzle assemblies. Each of the smart nozzles includes a target smart nozzle flow rate module configured to generate a target smart nozzle flow rate of the agricultural product based on the one or more sprayer characteristics. The target smart nozzle flow rate is adjusted according to the error correction.
