The device has a container, a nozzle arrangement, a conveyor device, a high-voltage source, a processor for processing measurement values, data and/or reference values, a storage device and a transmitting and receiving unit for transmitting the measurement values, data and/or reference values to an external data processing device and/or for receiving further measurement values, data and/or reference values from the external data processing device.

A method includes receiving a current data sample relating to a tractor spraying in an agricultural block, wherein the current data sample includes a current location; calculating a shortest distance from the current location to each of a plurality of borders of the agricultural block; selecting a current sample lowest distance, the current sample lowest distance being a lowest one of the shortest distances; grouping the current data sample with at least one prior data sample to produce a line of data samples, wherein each of the at least one prior data sample has a corresponding prior sample lowest distance; calculating an average lowest distance for the line of samples; comparing the average lowest distance to a threshold distance; and discarding the current data sample and each of the at least one prior data sample if the average distance is less than the threshold value.

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.

A robot controller is adapted to execute a program an indication of a setpoint speed of a robot arm, an indication of a contemporaneous setpoint fluid flow per unit time of a spray gun supported by the robot arm, and an indication of a contemporaneous further setpoint quantity of the spray gun. The robot controller is configured to obtain an estimate of actual speed of the robot arm; determine whether the estimate deviates from the setpoint speed; and, in case of a deviation, adjust the setpoint fluid flow per unit time in accordance with a first compensation function. In an embodiment, the robot controller is further configured to concurrently adjust, in case of a deviation, the further setpoint quantity in accordance with a second compensation function, which is different from the first compensation function.

A spray applicator (1) for spraying a fluid onto a web (W) of material has a first group of spray nozzles (10A) arranged along a first axis (FA) and a second group of spray nozzles (11A) arranged along a second axis (SA). The first (FA) and second (SA) spray nozzle axes are arranged on the same side of a plane in which the web (W) is run. Each spray nozzle (10A, 11A) has an elongated spray opening configured to spray fluid in a direction towards the web (W). The first spray nozzle opening of the first group of spray nozzles (10A) has an inclination angle which differs from the second nozzle opening inclination angle of the second group of spray nozzles (11A).

A controller for an agricultural sprayer machine is configured to receive for each of a plurality of nozzle sets a respective upper pressure limit, a nozzle reference flow, and a nozzle reference pressure. For each one of the plurality of nozzle sets, a speed setpoint is calculated based upon the application rate setpoint, the nozzle reference flow, the nozzle reference pressure, and the product pressure setpoint.

A system and method for calibrating an irrigation system to account for variations in flow rates, motor operating parameters, and other parameters caused by field elevation changes, pipe friction losses, water emitter nozzle wear, pressure-regulator inaccuracies, and other factors. A calibration map is created to account for the flow rate variations or other parameters and then consulted to control operation of the irrigation system.

The invention relates to a method for coating an application surface (11) of a component (10), in particular of a building, within an application area (12) with a coating agent, in particular with a building paint, comprising a step of edge application to the application area (12) and a step of surface application to the application area (12), which does not include the edge application, characterised in that a first application method on the basis of the drop-on-demand method is used in the edge application step, and a second application method, which has a higher surface coating output than the first application method, is used in the surface application step.
