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.

The present disclosure is directed to a fluidic ejection device configured to detect whether one or more nozzles of the fluidic ejection device is in a normal state, a blocked nozzle state, or an accumulated fluid state. The fluidic ejection device includes an optical blockage detector having a light emitting device configured to emit a light signal, and a light sensor configured to detect the light signal. The optical blockage detector detects the normal state, the blocked nozzle state, and the accumulated fluid state based on the detected light signal.

Also provided are use of remote data repositories and/or processing devices that for processing and use of such data.

A water spray wand comprises an internal water pipe, a spray handle, a compartment for a battery and a light. The spray handle is configured such that when the flow of water is permitted through the spray wand, the electronic communication between the battery compartment and the light is completed, and when the flow of water through the spray wand is interrupted, a timer is activated to interrupt the electronic communication between the battery compartment after a predetermined delay.

A monitoring system for an agricultural sprayer includes a spray nozzle, a pressure sensor, a flow rate sensor, and control circuitry. The spray nozzle is configured to generate a spray of a fluid, the pressure sensor is adjacent to the spray nozzle and is configured to measure a pressure of the fluid sprayed by the spray nozzle, and the flow rate sensor is adjacent to the spray nozzle and is configured to measure a flow rate of the fluid sprayed by the spray nozzle. The control circuitry is configured to receive the measured pressure from the pressure sensor, receive the measured flow rate from the flow rate sensor, and cause a user interface to display the measured pressure and the measured flow rate. Related methods and systems are also disclosed.

A method of monitoring agricultural spray performance includes spraying a fluid from spray nozzles, sensing spray parameters (e.g., droplet size, a flow rate, an application density, or a pressure of the fluid) for the spray nozzles, receiving the spray parameters, generating an average spray parameter value, determining a minimum spray parameter value and a maximum spray parameter value, and displaying the average, minimum, and maximum spray parameter values. Other methods include spraying a fluid from a spray nozzle, sensing a spray parameter for the spray nozzle, detecting that the spray parameter has exceeded a pre-defined threshold value, displaying an alarm, and ceasing spraying the fluid from the spray nozzle. A user interface continues to display the alarm after the act of ceasing spraying the fluid. Related systems and other methods are also disclosed.

An apparatus for manufacturing a display device includes: a stage configured to hold a substrate; a movement unit configured to move relative to the stage; a head unit arranged on the movement unit and including a nozzle for discharging a liquid droplet onto the substrate; and a sensor unit configured to emit a laser to irradiate the liquid droplet falling from the head unit to the substrate to sense a portion of a planar shape of the liquid droplet. The apparatus is configured to control the movement unit or the head unit based on the sensed portion of the planar shape.
