A fluid application system includes a pump unit configured to pump a fluid to a fluid applicator. The fluid application system includes a sensor configured to sense a motion made by a user and generate a sensor signal indicative of the sensed motion. The fluid application system also includes a control system configured to identify a gesture based on the sensor signal and control the fluid application system based on the identified gesture.

The embodiments herein discloses a semi-autonomous mobile robotic apparatus (100) that can apply primers and paints and perform other operations such as wall sanding, drawing abstract wall art on the interior walls of buildings. The disclosed semi-autonomous mobile robotic apparatus (100) apparatus comprises of at least 13 numbers of type-1 (403) and at least 2 numbers of type-2 (405) ultrasonic sensors coupled to the apparatus (100), at least 2 Light Detection and Ranging (LiDAR) sensors (401 and 402) coupled to the apparatus (100), a human machine interface module (102) adapted to receive one or more inputs from a user (101) and provide the data to the microprocessor (103) for processing inside the apparatus (100) and provide output to one or more modules (104 and 105) to perform the relevant painting, sanding, putty application or abstract wall art drawing operations.

Web lifter and/or stabilizer and method of lifting and/or stabilizing a travelling web and for coating a web. The device creates a web hold down force via a negative pressure slot at its exit side, which draws the web down against the surface on the entry side. The device can be actuated to move the web relative to a slot die coater off the die lips and stop the application of slurry to the web, thereby creating uncoated regions on the web surface. The device can then be actuated to move the web back into contact with the coater to start the application of slurry to the web, thereby creating coated regions on the web surface. Web lifting can be accomplished by rotating the device in first and second directions to lift the web off of the slot die coater and return the web back into contact with the coater.

An aeroponics system includes a spray manifold with a fluid inlet, a plurality of fluid injectors attached to the spray manifold and in fluid communication therewith, and a fluid pump in communication with the fluid inlet of the spray manifold. A timing controller is in electronic communication with the plurality of fluid injectors. A power source is in electronic communication with the fluid pump, the plurality of fluid injectors, and the timing controller. The fluid pump is configured to maintain a constant high pressure within the spray manifold. The timing controller is configured to control the timing and pattern of energization of the plurality of fluid injectors. When any one of the plurality of fluid injectors is energized, fluid is allowed to pass from the spray manifold through that fluid injector.

In some implementations, a controller may receive an input that indicates a proportion of a spray cycle in which a fluid spray system is to be active. The fluid spray system may include at least a first fluid pump configured to supply fluid to a first fluid spray bar and a second fluid pump configured to supply fluid to a second fluid spray bar. The controller may determine, in accordance with the proportion, a spraying timing for the first fluid pump and the second fluid pump that minimizes an overlap of an active time of the first fluid pump and an active time of the second fluid pump, and/or an overlap of an inactive time of the first fluid pump and an inactive time of the second fluid pump. The controller may cause activation of the first fluid pump and the second fluid pump in accordance with the spraying timing.

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 mixers 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 fitted 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.
