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.

In one aspect, a system for controlling the operation of agricultural sprayers may a vision-based sensor configured to capture data indicative of one or more features within a field across which an agricultural sprayer is traveling. A controller of the system may be configured to identify the one or more features within the field based on the data received from the vision-based sensor and determine a position of a boom component of the agricultural sprayer relative to the one or more identified features. Furthermore, the controller may also be configured to initiate a control action to adjust the position of the boom component when it is determined that the relative position between the boom component and the one or more identified features is offset from a predetermined positional relationship defined for the boom component.

A paint sprayer array may include an array frame. The array frame may include a first support member. The paint sprayer array may include an array mount. The array mount may include an array support member. The array mount may be detachably mountable to the array frame. The paint sprayer array may include a plurality of sprayers. Each sprayer of the plurality of sprayers may be detachably mountable to the array support member of the array mount and operable to selectively atomize paint. The paint sprayer array may include a sprayer activation assembly. The sprayer activation assembly may be operable to selectively activate at least a portion of the plurality of sprayers. The paint sprayer array may be selectably mountable to an aerial work platform. The aerial work platform may move the paint sprayer array to paint a large work surface.

Environmental sanitizing device including a frame housing a disinfectant liquid reservoir and supporting a nozzle, the nozzle associated with a generation system of an air flow within which a plurality of disinfectant liquid particles are suspended to sanitize a closed environment in which the device can be positioned; the nozzle is movable with respect to the frame, and associated with positioning system controlled by a control unit for orientation of the nozzle with respect to at least two mutually perpendicular axes, preferably around a first vertical axis and around a second horizontal axis to automatically orient the nozzle in desired direction with respect to the frame during a sanitization step, the nozzle coupled with at least one distance detector able to determine distance between the nozzle and an obstacle facing the nozzle.

A device (100) for firing a projectile at a target body, in particular a fluid projectile or solid projectile, comprises a hand-held unit (100) for firing the projectile, the hand-held unit (100) comprises a propulsion drive (114) for accelerating the projectile and a distance measuring device (112) for measuring a distance between the hand-held unit (100) and the target body. The device (100) also comprises an energy store (120) for operating the propulsion drive (114), the propulsion drive (114) comprising a control unit (115), whereby the propulsion (114) is controllable in dependence on the distance measured.

Disclosed is a method for controlling the pattern-width of a coating liquid dispensed from a nozzle. The method includes the steps of: dispensing the coating liquid downward from the nozzle in a dispensing position on a measurement reference line to photograph with a camera positioned at a predetermined horizontal distance from the measurement reference line arranged perpendicularly to a coating reference surface; calculating the pattern-width of the coating liquid on the coating reference surface from image data obtained by photographing the coating liquid dispensed from the nozzle in the dispensing position with the camera; comparing the calculated pattern-width of the coating liquid with a coating liquid reference pattern-width; and adjusting dispensing pressure by increasing or decreasing pressure of air supplied to a pressure container that provides the coating liquid to the nozzle when the calculated pattern-width of the coating liquid is outside the reference allowed error.

A film forming device 10 including a distance measurement unit 30 for measuring the distance between the skin S and the device 10, a distance decision unit 31 for deciding whether the distance measured by the distance measurement unit 30 is proper for electrostatic spraying, and a distance notification unit 32 for notifying a user of the decision by the distance decision unit 31. The film forming device 10 is of hand-held type small enough and configured to be held by the user's hand. The device 10 preferably includes an angle measurement unit 42 for measuring the angle between the electrostatic spray direction and the skin S.
