An apparatus and method for simulating the effects of dew are disclosed. The apparatus includes a moveable platform; a rotatable base, the rotatable base being connected to the platform; and a plurality of elongated rods for penetrating and spraying beneath the surface of a windrow. The rods radiate from a longitudinal axis of the rotatable base.

The invention relates to an agricultural distribution machinehaving a distribution linkage for applying agricultural material with two lateral booms, each having a plurality of application elements for applying the material, and a method of operation thereof. The distribution machine includes a controllable actuating device for altering a position of the distribution linkage relative to a target agricultural area to be worked, a sensor device configured to sense in anticipation changing vertical distances between the distribution linkage and the target area and/or upcoming changes in contour of the target area, and a control device that, for the purpose of controlling the position, preferably controlling the height, of the distribution linkage, is configured to generate actuating signals for the actuating means based upon the changing vertical distances sensed in anticipation and/or changes in contour, in order to at least partially reduce a response time in the position control device.

A portable, hand-held electrospinning or electrospraying apparatus and system, method, and portions thereof, comprised of a durable portion of the hand-held apparatus and a consumable portion of the hand-held apparatus. The consumable portion of the hand-held apparatus, which may contain the solution to be output in electrospin or electrospray fashion, may be replaced in whole or in part to provide additional or alternative solution. A base station may be provided, and can output high voltage and communication signals to the hand-held apparatus to enable the electrospin or electrospray operation by the hand-held apparatus.

Embodiments of the disclosed subject matter provide a device having a print head that includes a micronozzle array of depositors to deposit a material on a substrate. A reflective optical device may reflect a signal output by at least one optical sensor, and to reflect the signal from a surface of the substrate to the optical sensor. A processor may determine a distance between the optical sensor and the target surface of the substrate. The device may include one or more actuators coupled to the at least one print head to move the print head relative to an internal reference frame and adjust a position of the print head to the substrate. The sensor may be fixedly coupled with a mount to the internal reference frame. The print head may be configured to move independently of the optical sensor in at least one axis of linear or rotational motion.

A handheld fluid spraying system includes a pump assembly configured to provide a pressurized liquid and a handheld fluid sprayer. The handheld fluid sprayer comprises a fluid inlet configured to receive the pressurized liquid, a spray tip having an outlet through which the pressurized liquid exits the handheld fluid sprayer to be applied to a surface, a trigger configured to control flow of the liquid through the handheld fluid sprayer, and a sensor configured to detect the liquid and to generate sensor data indicative thereof, the sensor being selected from the group consisting of an infrared (IR) sensor, a thermal imager, and a UV sensor. The handheld fluid spraying system further comprises a controller configured to determine a characteristic of the liquid based on the sensor data and to generate a control output based on the determined characteristic.

A method of spraying paint using a painting assembly attached to a distance measuring wheel includes: receiving, by a communication device of the painting assembly, a control signal for controlling a driving device of the painting assembly; and based on the control signal, controlling a paint spraying state of a paint can attached to a paint can fixing device.

An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

The present invention is directed to a spray applicator for spraying a tissue treatment medicant onto a tissue that has a container containing the medicant and is positioned at a proximal end of the spray applicator; a spray tip positioned at a distal end of the spray applicator; a cannula connecting the container with the spray tip; an actuatable dispensing mechanism at a proximal end of the applicator to express the medicant from the container through the cannula and through the spray tip toward the tissue; an optional pressurized gas source discharging a gas through the cannula in the vicinity of the spray tip or inside the spray tip; and a distance indicator that provides indicia of the distance between the spray tip and the tissue but does not prevent positioning the spray tip closer to the tissue than a defined distance for the distance indicator.

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.

An apparatus for coating or encapsulating articles, having a drum with a perforated wall rotatably assembled in a wrap-around chamber and suitable for containing and stirring a batch of articles to be coated; a dispenser group with one or more nozzles for spraying a coating product; a gas inlet to direct clean drying gas against the perforated wall and a gas outlet to extract from the chamber dirty drying gas. An adjustable closure system is interposed between the drum and the gas outlet of the chamber, defining a passage for the dirty drying gas smaller than the passage by the gas outlet and further displaced or concentrated coinciding with the area of the wall of the drum that is effectively covered by the batch of articles. An automated adjustment of the locking system is envisaged, taking into account the position of the nozzles within the drum.
