Embodiments of the present disclosure relate to water fountain structures, and more specifically relate to modular fountain structures that include an adjustment bezel for changing a flow of water via an adjustable valve housed within them fountain structure. Adjustments to the valve to adjust the flow of water are effected by accessing the valve at the site of the fountain structure. The adjustment bezel or other manipulable device is incorporated with each fountain structure to provide control for flow of water emitted from the fountain, as the adjustment bezel is accessible without removal and/or disassembly of the fountain structure.

A device for cleaning an optical surface of a sensor of a vehicle including at least one segment that has a circular-arc shape with a cleaning fluid circulation channel. The segment including at least one cleaning fluid inlet in the channel and at least one nozzle for spraying cleaning fluid toward the optical surface from the fluid circulation channel. The at least one nozzle includes a cleaning fluid outlet duct and a deflector, and the deflector extends in line with the duct, the deflector being able to deflect the flow of cleaning fluid by a given angle toward the optical surface.

A hands-free footwear and foot cleaning device which allows the user to clean the bottom or the sole of the footwear as well as the exterior surrounding sides of the footwear. The device can also be used to clean a user's bare foot. The device utilizes a plurality of rollers and a series of water line sprayers that are adapted to spray in a direction to contact one or more of the side portion, bottom portion, or top portion of the sole of a footwear or foot. The sprayers are activated by either a sensor or a pressure devise. The device may also include the option of incorporating additional elements for the purpose of cleaning bare feet rather than just the bottoms of the footwear.

An agricultural device includes a boom having a supply line for transporting liquid product and nozzles along the boom, each nozzle operatively connected to the supply line. A liquid product supply is connected to the supply line for supplying the liquid product to be sprayed. A pressure regulation unit includes a nozzle controller for controlling opening and closing of a nozzle. A speed detector measures speed of the device. The pressure regulation unit and/or the nozzle controller calculate nozzle timing data for each nozzle including a spraying frequency and a maximum closing time. The speed is provided to the pressure regulation unit and/or the nozzle controller for calculation of nozzle operation data. The nozzle controller operates each of the nozzles based on the calculated nozzle timing data and the maximum closing time is not exceeded to obtain a homogeneous spraying of the liquid product over a surface of a field.

A telescopic nozzle device for cleaning a vehicle surface comprises a housing having a fluid inlet channel and a rod opening that opens towards the inside of the housing at one end of the rod opening and opens towards the outside of the housing at a second end of the rod opening. The device further comprises a hollow nozzle rod having a rod channel, an inlet opening, and a nozzle for ejecting washing fluid from inside the rod channel to the outside of the nozzle rod. The nozzle rod is moveable between a retracted position and an extended position. The device also includes a guiding system that guides the nozzle rod between the retracted and extended positions.

A rain simulation system that replicates realistic raindrop characteristics for controlled testing is invented. The rain simulation system can be used as a stand-alone system with wind using a blower fan or in a wind tunnel, and without wind to create wind-driven and vertically falling rain droplets, respectively. In addition, methods to simulate rainfall for stationary and moving objects such as a road passenger vehicle are proposed. The rain simulation system is fully adjustable for a range of droplet size, impact velocity, rain intensity, rain coverage via the use of dripping nozzle devices and positioning of system components. The rain simulation system dispenses distinct droplets or continuous streams that can be broken down into droplets by wind. A rain nozzle device is coupled with a rain reservoir, and multiple nozzles are used to create a rain matrix, the full matrix is integrated with a rain rack and rainwater flow control strategy.

The present invention relates to a system for spraying cleaning fluid. The system includes a first spray nozzle and a second spray nozzle, each capable of receiving cleaning fluid and spraying it. The system also includes a directional valve with an inlet, a first outlet and a second outlet. The directional valve being capable of conveying cleaning fluid from the inlet to the first outlet when cleaning fluid received at the inlet has a pressure below a given threshold, and which is capable of conveying cleaning fluid from the inlet to the second outlet when the cleaning fluid received at the inlet has a pressure above the given threshold. The system further includes a pump capable of injecting fluid into the directional valve and capable of varying the pressure of the fluid.
