Applying a coating medium may include: emission of a coating medium jet from an application device and positioning the application device relative to the component with a particular application distance between the application device and the component, so that the coating medium jet impacts on the component and coats the component. The application distance (d) can be smaller than the disintegration distance of the coating medium jet, so that the coating medium jet impacts with its continuous region on the component.

Location systems and methods for locating paint and other markings on a surface are described. More specifically, but not exclusively, the disclosure relates to smart paint stick devices and methods of use in locating and marking buried utility lines or other buried objects. One system for locating a buried object may include a buried object locator and a paint stick. The locator may include a tracking component configured to detect a location of a buried object. The paint stick may be configured to cause a paint container to dispense paint at a first position associated with the location of the buried object. The paint stick may include a position determination component configured to transmit one or more range vector signals that are detected by the tracking component. Sensors may be used to determine when paint is dispensed from a paint container, and to determine a color of the paint or a type of a marking.

A sprayer that senses the presence or character of a surface to be sprayed includes one or more sensors configured to detect a presence or character of a surface to be sprayed; and a dispenser assembly including one or more components configured to modify at least one spray characteristic of a formulation based on an input from at least one of the one or more sensors indicative of the presence or character of the surface to be sprayed.

An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets

A coating apparatus can include a spray applicator configured to discharge a coating material toward a surface of a workpiece, wherein the spray applicator includes an air shaping orifice, and wherein the spray applicator is configured to generate an electric field between the spray applicator and the workpiece, and a positioning system configured to adjust a position of the spray applicator relative to the surface of the workpiece. It can further include a control system configured to regulate operation of the spray applicator and/or the positioning system to: maintain the spray applicator within a coating distance, maintain a flow rate of shaping air through the air shaping orifice, and maintain an electrical potential of the electric field.

Methods, systems, and apparatuses are disclosed for controlling the release of a coating material to a substrate surface, with the system and apparatuses emulating an experienced human artisan by sensing condition parameters and substrate parameters and comparing parameters to stored parameter values and value ranges.

A method for inspecting and repairing a surface of a component of a gas turbine engine, the method including: inserting an inspection and repair tool into an interior of the gas turbine engine; inspecting the surface of the component with the inspection and repair tool; performing a repair of the surface of the component with the inspection and repair tool from within the interior of the gas turbine engine, the inspection and repair tool remaining within the interior of the gas turbine engine between inspecting the component and performing the repair of the surface of the component.

A liquid discharge apparatus includes a head, a position changer, and circuitry. The head has a nozzle. The head discharges a liquid from the nozzle to apply the liquid onto a surface of an object. The head has a prescribed discharge condition. The position changer changes a relative position between the object and the head. The circuitry determines a linear trajectory along which the position changer moves the head based on the prescribed discharge condition, outputs a first command including multiple moving positions along the linear trajectory to the position changer to cause the position changer to move the head along the linear trajectory, and outputs a second command including multiple discharge positions to the head to cause the head to discharge the liquid at the multiple discharge positions.

The present disclosure involves systems for applying finishing treatment to balls. The system includes an arm that transports at least one ball through a plurality of stations. A first station includes a first actuator, which permits introduction of a ball into the arm. A second station includes a buffer, which buffs the surface of the ball and rotates the ball in place relative to the arm, a spray nozzle configured to apply treatment to the ball, and a camera configured to capture images of the ball. A third station includes an inspection camera that captures inspection images of the ball and a rotating plate configured to rotate the ball in place relative to the arm. A fourth station includes a second actuator, which ejects the ball from the arm.

Disclosed is an integrated pump assembly for a liquid dispensing device and a liquid dispensing device thereof. The pump assembly for the liquid dispensing device comprises a flow path board formed with a flow path therein to receive liquid from a liquid source and dispense a gas-liquid mixture, a gas-liquid mixing pump connected with the flow path board to receive the liquid therefrom and return the gas-liquid mixture thereto, and a main control board for controlling the operation of the gas-liquid mixing pump, wherein the flow path board comprises an upper board and a lower board fitted to each other with the flow path formed therebetween. The liquid dispensing device comprises a housing, said pump assembly configured to be accommodated in said housing and a power supply to supply power to said pump assembly.
