Disclosed is a workpiece processing apparatus that performs a predetermined processing on a workpiece. The workpiece processing apparatus includes: a workpiece table configured to place the workpiece thereon; a processor configured to process the workpiece placed on the workpiece table; a movement mechanism configured to relatively move the workpiece table and the processor; a position measuring device configured to measure a position of the movement mechanism; a detector configured to detect a position of the workpiece placed on the workpiece table; and a corrector configured to calculate a positional correction amount of the workpiece table based on a measurement result of the position measuring device and a detection result of the detector.

The present invention provides a surface following nozzle, an observation device for a moving object surface, and an observation method for the moving object surface that can remove water in the vicinity of the nozzle while following changes in the shape and changes in the distance of a moving object. A surface following nozzle includes a nozzle that injects gas from a tip end thereof, a separating part that closes a base end of the nozzle, and an extending and contracting part that is provided at a rear side of the nozzle via the separating part, and extends and contracts along an axial direction of the nozzle. The extending and contracting part includes an elastic body that applies a forward force with respect to the nozzle.

An automated mobile sprayer (AMS) (10) applies fluid sprays to a target surface. The AMS can operate according to a wall-follow routine, where the AMS maintains a spacing and orientation relative to the target surface and shifts a set distance between each spray pass. The AMS is also operable in an overlap adjustment mode where a control module (24) of the AMS actively determines the distance that AMS shifts between each spray pass such that AMS applies the final orthogonal spray on the target surface at an end point of the target surface.

Described herein are apparatuses and methods for conditioning particles. In some embodiments, the apparatuses and methods are configured for first-in-first-out transit of particles through a chamber containing a conditioning fluid.

An automated mobile sprayer (AMS) (12) is configured to apply stripes of fluid to target surfaces to coat those target surfaces with the fluid. A control module (24) of the AMS (12) controls movement and spraying by the AMS. The control module (24) causes the AMS (12) to follow a target surface based on distance data from distance sensors configured to detect the target surface.

The invention relates to a modular system for weed control for a rail vehicle. The modular system has a control unit for producing control signals for controlling valves and miners in a separate herbicide and mixing module and for producing a second set of control signals for controlling valves of a nozzle rod. The herbicide and mixing module has a container for holding different herbicides and electrical connection elements for connections to the control unit. Furthermore, a nozzle rod is present, which is tit ted with a nozzle set, in order to spray herbicides of the herbicide and mixing module. In addition, a camera module is present, which produces a weed signal in response to the detection of a weed, in order to control the spraying of the herbicides. The camera module is at such a distance from the nozzle rod that, despite high speed, there is sufficient time to provide the herbicide at the nozzles.

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.

A sensor kit is provided to be used with a spray gun. The sensor kit may acquire relevant data while the spray gun is being used, and provide feedback to the user of the spray gun on particular parameters of the spray job such that the user in real-time can adjust his method of spraying. Furthermore, the feedback may be adjusted for different types of coatings using pre-determined data related to a specific coating. Even further, the obtained data during spraying may be sent to a remote server where data may be collected of a plurality of spray jobs using a particular type of coating. Using the obtained data during spraying, it may be possible to reconstruct what the applied coating looks like, and/or what the surface looked like on which the coating has been applied.

A kind of real-time measurement system and method for height from spray boom to crop canopy was provided in present invention patent, which includes the following steps. Step 1: Calibration for ultrasonic ranging sensor; Step 2: Determination of included angle for two ultrasonic ranging sensors; Step 3: Collection of relative height between spray boom and crop canopy; Step 4: Anti-interference processing for height data; Step 5: Calculation of relative height from spray boom to crop canopy. Its characteristic lies in: two ultrasonic ranging sensors with a certain angle are installed at each end of the spray boom, the height of crop canopy was acquired under the control of control unit, and the relative height from spray boom to crop canopy was obtained by the anti-interference analysis and data conversion, the accurate monitoring for relative height from spray boom to crop canopy was realized while the spray boom is tilted. It breaks through the technical bottleneck that the relative height of the spray boom and the crop canopy cannot be accurately obtained when the spray boom tilts due to turbulence in the field operation of the spray boom sprayer, and lays a technical foundation for the dynamic adjustment of the balance and height of the spray boom.

Provided is an unmanned aerial vehicle including: a discharge port configured to discharge contents in a container; an expansion/contraction unit configured to connect the discharge port and the container and be expandable; and a discharge position control unit configured to control expansion/contraction of the expansion/contraction unit.
