A fluid application system includes a fluid supply line connected to a fluid supply, a plurality of nozzle assemblies connected in fluid communication with the fluid supply line, and a return line. Each nozzle assembly includes an inlet connected to the fluid supply line, a nozzle defining a spray outlet, a return line outlet, and an electrically actuated three-way valve fluidly connected between the inlet and each of the spray outlet and the return line outlet. The three-way valve is configured to alternately direct fluid from the inlet to the return line outlet and the spray outlet. The return line is connected in fluid communication with the return line outlet of each nozzle assembly, and is configured to direct fluid from the return line outlet to the fluid supply line.

A sprayer equipment includes a support frame, a pump, a pressure regulator, a concentrate tank, an injector, a spray nozzle, and a controller. The support frame has a plurality of wheels. The pump is coupled to the support frame and includes a pump inlet configured to be fluidly coupled to a water source and a pump outlet providing water at an increased water pressure. The pressure regulator is configured to control the pressure of the water. The concentrate tank is supported by the support frame and configured to store a concentrate fluid. The injector is fluidly coupled to the concentrate tank and configured to inject the concentrate fluid into the water. The spray nozzle is fluidly coupled to the pump outlet and the injector. The controller is coupled to the injector and is configured to control operation of the injector.

Methods and apparatus for removing deposits in self-assembled monolayer (SAM) based selective deposition process schemes using cryogenic gas streams are described. Some methods include removing deposits in self-assembled monolayer (SAM) based selective depositions by exposing the substrate to cryogenic aerosols to remove undesired deposition on SAM protected surfaces. Processing chambers for cryogenic gas assisted selective deposition are also described.

One or more techniques and/or systems are disclosed for a center frame positioning method for an agricultural sprayer. The method comprises activating a center frame positioning system and collecting and processing position data related to a position of a suspended center frame in the center frame positioning system. The method further comprises evaluating the position data to determine whether any adjustment to the position of the suspended center frame is needed and controlling actuator force in at least one actuator to adjust the position of the suspended center frame based on the evaluating the position data.

A thermoplastic extrusion vehicle for continuous processing of thermoplastic material used for applying lines and stripes to a roadway. Heated oil from a burner is directed to a common reservoir having a section for oil distributed to the extremities of the vehicle and a main section for heating of melting kettles; the common reservoir having a divider wall capable of maintaining two different temperatures within the reservoir. A programmable logic controller displays and records the mil thickness of lines that is calculated according to the volume of material consumed at the rate of application based upon the speed of the vehicle.

Various embodiments relate generally to computer vision and automation to autonomously identify and deliver for application a treatment to an object among other objects, data science and data analysis, including machine learning, deep learning, and other disciplines of computer-based artificial intelligence to facilitate identification and treatment of objects, and robotics and mobility technologies to navigate a delivery system, more specifically, to an agricultural delivery system configured to identify and apply, for example, an agricultural treatment to an identified agricultural object. In some examples, a method may include receiving data representing actions to be performed relative to a subset of agricultural objects, positioning an emitter of an agricultural projectile delivery system adjacent to an agricultural object, identifying a corresponding action to be performed in association with the agricultural object, selecting an emitter to perform the action, and causing the emitter to emit an agricultural projectile to intercept the agricultural object.

A robotic system for applying a volatile fluid to a work-piece comprising a support structure configured to mount at least one spray nozzle while facilitating motion of the nozzle in multiple degrees of freedom. An encoder senses a position of the spray nozzle and issues a position signal indicative thereof. A pneumatically-driven motor effects displacement of the spray nozzle on the support structure along each degree of freedom. A controller disposed outside the boundaries defined by the structural support, is responsive to the position signals for controlling the pneumatically-driven motor to displace the spray nozzle while dispensing the volatile fluid. The pneumatically driven motor and the isolated spatial position of the controller prohibits a source of ignition for the volatile fluid sprayed by the nozzle.

Embodiments include individual physical spray nozzles that have passageways inside to combine fluids that flow out of the spray nozzles. The nozzles have at least two valves that are opened and closed in an interleaved manner. The nozzles have multiple outlets. Such nozzles are mounted on a variety of implements including agricultural or industrial spray booms.

An agricultural sprayer includes a spray boom supported by a frame, a spraying system comprising a set of spray nozzles spaced along the spray boom, and a control system configured to control the spraying system to spray a liquid based on a target application to an agricultural field, generate a spray performance metric indicative of performance of the spraying system relative to the target application, and generate a control signal to control the agricultural sprayer based on the spray performance metric.
