A method of dispensing a brushable substance onto a surface comprises (1) with a cartridge positioned inside a sleeve between an inner tubular sleeve wall and an outer tubular sleeve wall, circumscribing the inner tubular sleeve wall, and also positioned between a twist-lock pressure cap, hermetically coupled with the cartridge, and a valve, communicatively coupled with the cartridge, linearly moving an annular plunger, received between an inner tubular cartridge wall and an outer tubular cartridge wall, circumscribing the inner tubular cartridge wall, toward the valve along a first axis to urge the brushable substance from the cartridge, through the valve, and to a brush that is communicatively coupled to the valve; and (2) controlling flow of the brushable substance from the valve to the brush.

An aerial vehicle includes a liquid chemical tank, at least one spray unit, a plurality of sensors, a processing unit, and an output unit. The processing unit is configured to generate a spray record for an environment within which the aerial vehicle is operating, the spray record comprising: information over a time period of at least one spray condition relating to one or more of the at least one spray unit for the aerial vehicle operating within the environment over the time period, the determined air movement direction relative to the projection of the fore-aft axis onto the ground over the time period, and the determined air movement speed relative to the ground over the time period. The output unit is configured to output the spray record.

An aerial vehicle includes a liquid chemical tank, at least one spray unit, at least one actuator, a plurality of sensors, and a processing unit. The processing unit is configured to determine an air movement direction relative to a projection of the fore-aft axis onto the ground and determine an air movement speed relative to the ground, the determination comprising utilization of the speed of the aerial vehicle, the air movement direction relative to the aerial vehicle with respect to the fore-aft axis of the aerial vehicle and the air movement speed relative to the aerial vehicle. The processing unit is configured to control at least one flying operation of the aerial vehicle and/or control the at least one actuator.

A sprinkler system for lawns and landscaping is custom-fitted to each particular lot or area to be irrigated. Each in-ground, pop-up, rotating sprinkler head has a pattern defining plate fitted therein having a central opening made therein, as by laser cutting, solid particle deposition, or the like, the opening being congruent with the area to be watered, as adjusted for any sloped portions of the area. A pattern sampling aperture aligned with spray nozzles of the sprinkler rotates about the opening in the defining plate, feeding an amount of water to each radial line of the area about the sprinkler sufficient to reach from the sprinkler position out to the periphery. A speed control comprising a spring-biased cam and an opposing turbine wheel in the water flow slows spray head rotation at arc portions of longer water throw and speeds rotation where the throw is shorter, thus to obtain substantially uniform water coverage over all parts of the area served by each sprinkler head.

An aerial paint spraying vehicle includes a body and a paint reservoir removably coupled to the body and configured to store paint. The aerial paint spraying vehicle includes a pressure vessel removably coupled to the body and configured to pressurize the paint from the paint reservoir. The aerial paint spraying vehicle includes a paint applicator assembly configured to receive the pressurized paint and expel the pressurized paint through a spray nozzle towards a target surface.

A method of processing a workpiece includes supporting the workpiece on a tailstock extending along an axis, thermally processing the workpiece with a processing device, and displacing a portion of the tailstock assembly in response to thermal expansion of the workpiece as a result of processing with the thermal processing device.

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.

A system for spraying plants comprises a location-determining receiver for estimating a position of a sprayer with respect to one or more rows of plants. A distance sensor is arranged to measure a distance between a nozzle assembly and a plant row segment. A guidance module is adapted to align the nozzle assembly with a target path between the rows of plants, such as a centered path between the rows, or offset between the rows of the plants. A first nozzle is targeted toward a first zone with respect to the plant row segment based on a first spray pattern of the first nozzle. A second nozzle is targeted toward a second zone with respect to the plant row segment based on a second spray pattern of the second nozzle. A nozzle selection module for selecting automatically a first nozzle or a second nozzle based on maximum coverage of a target zone around the plant segment based on the first zone, the second zone, and the measured distance.

The present utility model relates to an autonomous interior painting robot for homes, commercial premises, hotels, etc. The robot is designed for painting and outlining while recognizing obstacles in the work area and aimed at reducing the efforts and time needed to carry out these operations. It is applicable in the field of interior design and the completion of small conditioning works. The autonomous painting robot comprises a mobile base (1) equipped with a paint tank and a pump or compressor, characterized in that the base (1) comprises a series of detectors configured to locate the base (1) and to detect obstacles, a substantially vertical lifting column (4), at the end of which a robot arm (5) is articulated and topped with a head (6) that carries a paint gun (7) connected to the pump, one or more cameras (9), and a proximity sensor (10).
