The device (100) comprises a distance sensor (120) for measuring a distance (d) between the head (110) and surfaces in the area along the discharge direction (D). The device (100) is configured according to at least one of a first and second configuration. In the first configuration a rotational speed of the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120). In the second configuration a flow rate of the flow of liquid droplets from the head (110) is adjustable as a function of the distance (d) measured by the distance sensor (120).

A fluid discharger includes: a discharge nozzle configured to discharge fluid; a first rotation device configured to rotate the discharge nozzle; and a control device configured to control the first rotation device by remote operation. The control device includes a first mode control unit including a first automatic control unit configured to automatically perform reciprocating control of the discharge nozzle in a first rotation range set for each of the fluid dischargers; and a first switching unit configured to switch between a control signal to be outputted from the first automatic control unit and a control signal to rotate the discharge nozzle by a first rotation angle designated by remote operation. In a dust suppression system, this configuration can control the direction of the discharge nozzle by remote operation, and also can automatically reciprocate the direction of the discharge nozzle within a predetermined range.

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.

An application device includes: a discharger having a discharge port configured to discharge an application material; a first supporter movably supporting the discharger around a position of the discharge port; and a first driver configured to move the discharger supported by the first supporter. An application method, includes: making a central axis of a discharge port coaxial with any rotation axis in an arm portion of an application robot, the discharge port being configured to discharge an application material; and applying the application material to an applied surface while moving a discharger having the discharge port around a position of the discharge port.

A sprayer system including a wand, a rotary arm, a motor, a housing, a support, and a controller or control panel. The wand has a nozzle at one end. The rotary arm rotates around a first axle, and is connected at a distal end through a bearing to an opposite end of the wand. The housing covers or encloses a part of the wand, the rotary arm, and a rotatable ring through which the wand passes. The motor drives rotation of the rotary arm. The support mechanically supports the housing. The controller/control panel controls rotation of the rotary arm. The wand, the rotary arm and the ring are configured so that rotation of the rotary arm causes the nozzle to move in a circular, elliptical and/or oval pattern. Methods of making and using the sprayer system and software for controlling the system are also disclosed.

A repair machine is provided. The repair machine is structured to apply a repair fluid to a plurality of can ends. The repair machine includes a can end down stacker assembly, a can end conveyor assembly, and a spray assembly. The can end down stacker assembly is structured to move individual can ends from a stack to a conveyor assembly. The can end conveyor assembly is structured to transport the can ends over a path, the can end conveyor assembly including a number of reference locations. The can end conveyor assembly is disposed adjacent to the can end down stacker assembly and receives can ends therefrom. The spray assembly is disposed adjacent to the can end conveyor assembly downstream of the can end down stacker assembly. The spray assembly includes a locator assembly, a spray gun assembly, a motion assembly, and a control assembly.
