Abstract: A device to moving a water shooter is described. The device may contain features that allow the device to travel submerged in a reservoir with a water shooter attached. The device may travel along a fixed track, rotational boom, or be free swimming in order to move the water shooter within the reservoir so that unique water effects may be achieved.

Abstract: A water delivery device is described which includes an outlet pipe through which water is ejected to provide a water display. A disk is positioned relative to the outlet pipe. The relative positions of the disk and outlet pipe are moved so that the disk is located within the outlet pipe or above it to alter the appearance of the water leaving the outlet pipe. As the relative position of the disk and outlet pipe varies, a sequence of water expressions is provided.

Abstract: A system for configuring unmanned aircraft system (UAS) to a structure is disclosed. The structure may be a standing structure such as a tower. A movement system may be configured with the tower. The UASs may be tethered to the movement structure and the movement structure may move with respect to the tower.

Abstract: A packed bed catalyst in a pressurized vessel/reactor during contact with a dioxide species precursor enhances catalytic conversion of the precursor to the dioxide species, compared with the same catalytic conversion performed in a non-pressurized vessel/reactor.

Abstract: A water display is described whereby parabolic water streams may be controlled so as to appear to move towards or away from each other or step over each other.

Abstract: A method of treating biofilm having a protective extracellular polymeric substance (EPS) membrane attached to a surface applies chlorine dioxide to the biofilm attached a surface to disrupt the EPS membrane of the biofilm and thereby expose microbes in the biofilm to microbicide attack and death without detaching the biofilm from the surface.

Abstract: A display where water is applied onto the screen of a visual display monitor and graphics are presented on the display that coincides with the applied water is described. The timing of the water being applied to the screen and the playing of the graphics may be orchestrated such that the applied water seems to create the presented graphics. A controller may be used to control the water and the display.

Abstract: A light display system and device for use in a body of water or other liquid is described. The light display device may be controlled remotely via a control hub and/or control panel, or controlled by internally preprogrammed commands. A plurality of light display devices may be controlled in selected, choreographed sequences to provide various unique visual displays including, for example, geometrical patterns and/or naturalistic patterns giving the impression of organic phenomena such as swarming fireflies, bioluminescent creatures and the like.

Abstract: A method and apparatus use conductivity to control the dosing of various chemical additives used in the water treatment industry by modulating the chemical additives within threshold setpoints. Conductivity directly correlates to concentration of chemical additives. This correlation is used to modulate the dosing rates of chemical additives into a process water stream to consistently regulate and balance chemical additive concentration within the process water stream. For example, the method and apparatus dose chlorine dioxide precursor solutions into a process water stream to generate a consistent concentration of aqueous chlorine dioxide.

Abstract: An unmanned aerial system (UAS) that displays an image, video or other effect is described. The UAS may include a camera that captures the image for display. The UAS may be used in connection with a water display, and multiple UASs may operate together.

Abstract: A tethered unmanned aerial system (UAS) is described, wherein the flight of one or more UASs may be used in connection with a water and light display.

Abstract: A fire display that may reside under a viewing window or panel. The display may include a tray or channel along which a fire ball or fire wave may travel. The display includes a gas delivery system.

Abstract: An unmanned aerial vehicle (UAV) that includes a light and a cooling system is described. The light fitted to the UAV may be bright since heat it generates will be cooled by thermal conduction, convection and/or heat absorption. The light may be cooled by the airflow generated by the propellers. The cooling system of the lighted UAV may include radiator that may conduct heat to the environment and/or include an internal liquid cooling system. The cooling system may include dedicated fans to cool the lights.

Abstract: Speaker systems are provided, particularly for mounting in off-road vehicles, ATVs, UTVs, watercraft and motorcycles. The speaker systems may include a linear array of speakers and a housing encasing a backside thereof. In some cases, the speaker systems include a pipe-mounting clamp coupled to the housing for mounting the speaker system to a surface. In addition or alternatively, the speaker systems may include L-shaped mounting brackets arranged along opposing lateral sides of the housing for mounting the speaker system to a surface. In some cases, the housing includes a substantially uniform depth spanning opposing lateral sides of the linear array of speakers. In some embodiments, a speaker system may be suspended in proximity to an upper bar of a windshield frame, front roll bar, and/or front edge of a roof of a vehicle.

Abstract: Wafers on a first wafer carrier in a tank are lifted from the first wafer carrier and a bath in the tank so as to accomplish Marangoni drying of the wafers. The lifted dry wafers are positioned on a second wafer carrier in a chamber and shifted to an offset position. A barrier, which can be a wall of the chamber with or without a sweeping flow of gas, impedes the passage of deposits to the wafers arising during drying of the first wafer carrier. Static electricity can be discharged from wafer supports in the offset position.

Abstract: A water delivery device that may be used in a water display is described. The device includes an orifice or outlet through which water is shot out. The shape and configuration of the water device may be varied to dynamically adjust the configuration of the water shot out from the device. For example, the water delivery device may shoot out water in the shape of a fan, and the width of the fan may be varied.
