An atomizer for applying a coating includes a nozzle plate, an actuator, and an acoustic focusing device. The nozzle plate defines at least one aperture. The actuator is configured to oscillate to form pressure waves within a fluid to eject the fluid from the nozzle plate. The acoustic focusing device focuses the pressure waves toward the apertures.

A nozzle for an atomizer includes a plate, a piezoelectric actuator, a body, and a connector. The plate defines an aperture. The actuator is configured to oscillate the plate. The body supports the plate. The connector is configured to reversibly mount the body to the atomizer in a first orientation and in a second orientation. In the first orientation, fluid exits the nozzle along a first axial direction through the aperture. In the second orientation, fluid exits the nozzle along an opposite axial direction through the aperture.

A method of controlling application of material onto a substrate includes ejecting atomized droplets from an array of micro-applicators while the array of micro-applicators cyclically moves about at least one axis. The atomized droplets from each of the plurality of micro-applicators overlap with atomized droplets from adjacent micro-applicators and a diffuse overlap of deposited atomized droplets from adjacent micro-applicators is provided on a surface of the substrate. The array of micro-applicators cyclically rotates back and forth around the at least one axis and/or moves back and forth parallel to the at least one axis. For example, the at least one axis can be a central axis of the array of micro-applicators, a length axis of the array of micro-applicators, a width axis of the array of micro-applicators, and the like. Also, the array of micro-applicators can be part of an ultrasonic material applicator used to paint vehicles.

A method of controlling application of at least one material to a substrate is provided. The method includes configuring at least one array having a plurality of micro-applicators such that a subset of the micro-applicators is individually addressable to apply the at least one material to the substrate. Individually addressing the subset of micro-applicators provides control of a pattern width of a coating applied to a substrate, control of a flow rate of the material applied to the substrate, control of an angle of application of the material to the substrate, control of which and how many materials are applied to the substrate, and combinations thereof.

An apparatus for applying a coating to a substrate includes a base, an applicator, and a quick-connect connector. The base includes a fluid conduit. The applicator includes at least one actuator and an array of nozzle plates. Each nozzle plate defines at least one aperture. The at least one actuator is configured to oscillate the nozzle plates to eject fluid from the apertures. The quick-connect connector couples the fluid conduit to the applicator for fluid communication therebetween.

A material applicator for controlling application of at least one material on a substrate includes a housing and an array plate with an applicator array positioned within the housing. The applicator array has a plurality of micro-applicators and each of the plurality of micro-applicators has an ultrasonic transducer, a material inlet, a reservoir, and a micro-applicator plate with a plurality of apertures. The applicator plate is in mechanical communication with the ultrasonic transducer such that at least one material is ejected through the plurality of apertures as atomized droplets when the ultrasonic transducer vibrates the micro-applicator plate.

The invention is directed at systems and methods which provide for effective cleaning and drying of vehicles of different shapes and sizes. The invention in one example includes a vehicle washing apparatus comprising a conveyor system to move a vehicle along a path, and a bridge assembly supported above a vehicle and moveable along the length thereof. At least one trolley assembly is operatively supported by the bridge assembly and is moveable in a direction generally transverse to the movement of the bridge assembly. At least one cleaning arm assembly for delivering cleaning fluid to or for brushing the surface of a vehicle is operatively supported by the at least one trolley assembly or bridge. The cleaning arm assembly is moveable with the bridge assembly along the length of the vehicle, and transversely with the at least one trolley assembly to adjust the location of the cleaning arm relative to the vehicle, wherein the bridge assembly moves in association with movement of the vehicle to position the cleaning arm assembly adjacent at least a portion of the front, sides and rear of the vehicle as it moves along the path. A variable impact or patterning spray arm or drying system is also provided.

An oscillating sprinkler has two base rails which are parallel to each other. The base rails are interconnected by a bridge support and the sprinkler's water drive housing. Two pairs of elongated legs are rotatably mounted to the base rails. The legs can be aligned and positioned parallel and adjacent to, along the sides of the sprinkler to allow it to be used directly on the ground surface. The sprinkler's legs can be rotated down 90 so that they are perpendicular to the base rails and, since the distal ends of the legs are sharp and spike-like, they can be driven into the ground in order to set the sprinkler at any desired height. This permits watering at higher elevations. The legs can also be adjusted and positioned at a variety of configurations for watering at different angles.
