A system includes a material sensor system having an inlet and an outlet. The inlet receives a flow of a material and the outlet outputs the flow of the material. The material sensor system includes an inner cavity having a surface, where the inner cavity receives the flow of the material. The material sensor system also includes a float system having one or more floats, where the one or more floats float within the material of the inner cavity. The material sensor system also includes a switch that sends one or more signals to a control valve system when the float system engages the surface of the inner cavity.

An agricultural application system can include a nozzle assembly positioned along a boom assembly and can be configured to selectively dispense an agricultural product therefrom. One or more sensors can be operably coupled with the boom assembly and configured to capture data associated with first and second application variables. A controller can be communicatively coupled to the one or more sensors. The controller can include a processor and associated memory. The memory can store instructions that, when implemented by the processor, configure the controller to receive the data associated with the one or more application variables and calculate the spray quality index. The first application variable can have a first scaling factor and a second application variable can have a second scaling factor. The second scaling factor may differ from the first scaling factor.

The present invention, in some embodiments thereof, relates to a spreader for spreading paste (for example a tile adhesive) over a surface and more particularly, but not exclusively, to a system for pumping and uneven spreading of adhesive along a surface of a building. For example, the system may include a source of the paste optionally including a mixer, driver and/or conveyer. The paste may be driven to a spreader. For example, the spreader may deposit the paste unevenly over a surface. For example, the spreader may include multiple outlets and/or an uneven spreading blade (for example in the form of a comb). For example, the paste may be spread as lines across the surface.

According to another aspect, provided is a liquid diffuser system comprising an electronic device and at least one liquid diffuser. Other example embodiments are also described. In certain embodiments, the liquid diffusers allow easy, single-hand manageable, leakage-proof and hygienic replacement of the liquid containers. In certain embodiments, the liquid diffusers provides a smart system to manage or control the time for diffusion and the type of liquid to be used in response to user's requirement and/or data collected from the environment.

[Problem to be solved] Provided is a painting robot capable of realizing at least one of improvement in movement performance, reduction of the influence of a water head pressure difference, and prevention of occurrence of a state in which the pressure cannot be adjusted by a first adjustment valve and a second adjustment valve.

[Means for solving the problems] The painting robot 10 comprises a robot arm R1 attaching the painting head unit 50 to the tip, a paint supply mechanism 70 disposed between the robot arm R1 and the painting head unit 50, and a control unit 100, the control unit 100 comprising a paint supply means 90, a paint supply control unit 140 that performs control of at least one actuation of the paint supply means 91, the first adjustment valve 92 and the second adjustment valve 93 so as to be a pressure set point read from the control memory 141, and controls operation of at least one of the paint supply means 90 and the paint recovery means 91 while adjusting the openness of the first adjustment valve 92 and the second adjustment valve 93 within a predetermined adjustment range when controlling the pressure of the paint to be a pressure set point.

A device for dispensing a fluid topical composition includes a reservoir storing the composition and dispensing a pressurized flow of the composition. The device also includes an accumulator having an expandable chamber in fluidly communication with the reservoir. The chamber is biased towards a deflated configuration so that, when filled with the composition the chamber expands against this bias applying pressure to the composition stored therein. The device includes a supply valve regulating the flow of the composition from the reservoir to the accumulator, and a pressure sensor. The device further includes a processing arrangement analyzing data from the sensor to determine whether pressure in the accumulator is above a predetermined threshold and controlling the supply valve to maintain the pressure within a desired pressure range. The device also includes a deposition arrangement dispensing the composition from the accumulator under control of the processing arrangement.

A spray gun includes first and second air outlet channel arrangements. At least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the first arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the second arrangement can be controlled independently of one another in an open and/or closed loop manner. The spray gun also includes a third air outlet channel arrangement and at least one parameter, in particular pressure, volume flow and/or flow speed of air flowing through the third arrangement can be controlled in an open and/or closed loop manner independently of at least one parameter of the first arrangement, and/or independently of at least one parameter of the second arrangement. Thus, three different types of air (atomisation, shaping, and transporting) can each be controlled independently providing increased flexibility in use for different painting tasks.
