Disclosed is a facility including an artificial wave generator having an element for driving moving water along a predetermined path, including a first body profiled as a hydrofoil, orientated upright, having a leading edge towards the front, a trailing edge towards the rear, first and second main faces extending respectively on a first side and a second side, between the leading and trailing edges, and being configured with respect to the path so that when the generator is in service, a lift force directed towards a wave development zone is applied on the first body; and a second body profiled as a hydrofoil, orientated horizontally, having a leading edge towards the front, a trailing edge towards the rear, first and second main faces extending respectively on a first side and a second side.

A virtual reality-based exercise device includes a fitness device including a main exercise unit providing a predetermined exercise function to a user, a virtual reality device connected to the fitness device to communicate therewith, and a control unit connected to a server to communicate therewith and controlling the main exercise unit, based on information output from the virtual reality device. The control unit receives score information related to the predetermined exercise function stored in the server and provides the score information to the user through the virtual reality device.

A protective case for large objects including a lock housing formed from a first section and a second section, both of the sections including at least one external subsection and at least one internal subsection configured to telescope inside the external subsection; and an extension lock comprising a lock housing and a compression lock, the lock housing including a screw-threaded channel, and the compression comprising at least one screw-threaded shaft with a compressive component on the interior end and a lock handle on the exterior end, the screw-threaded shaft configured to matingly engage with the screw-threaded channel of the lock housing; the compression lock configured to descend in the lock housing and compressingly lock the internal subsection in an extended position upon locking rotation of the compression lock; and the compression lock configure to ascend in the lock housing upon unlocking rotation of the cam latch.

Disclosed in the current invention is a way to build a low cost and highly efficient surf pool by using diverging and converging swells to create waves for surfing. When a plurality of individual plunger wave generating devices or a single triangle pyramid shaped plunger, force a diverging swell into a first end of a surf pool. The swell then diverges or expands outward until the swell is wide enough to break over an artificial surfing reef. When a plurality of individual plunger wave generating devices in different opposite locations in the surf pool pushes a swell into the surf pool, as the swell transverses it converges into a single swell, which then continues to travel and breaks over an artificial surfing reef.

A base and method of using a base on a treadmill in which the base comprises three or more first ball bearing assemblies, each ball bearing assembly comprising a ball and a mounting assembly, the base also comprising one or more lower ball bearing assemblies, each lower ball bearing assembly comprising a lower ball and a lower mounting assembly, wherein each lower ball bearing assembly projects down from a plane defined by three or more of the ball bearing assemblies. A base may be attachable to or integrated into a piece of sports footwear or a board of a board sport. A user standing on footwear or a board with one or more bases may rock in one or more direction on the sports footwear to produce a leaning effect wherein one or more lower ball bearing assemblies and two or more ball bearing assemblies contact the ground.

A wave generating apparatus mobile application controller and method are provided in which a mobile controller actuates a plurality of wave generating chambers in sequence using a delay between the actuation of each chamber to produce a rideable wave in a pool. The mobile application controller allows the user to select the exact type of wave to be produced by the wave generator apparatus by selecting the size, shape, and pattern of the wave. The application also allows the user to use a camera to photograph or record herself or someone else, even while riding a wave.

A trick scooter comprising a base plate, a support member, comprising a first end and a second end, a handle, comprising a first end and a second end, wherein the handle is attached to the second end of the support member. Furthermore, the base plate is manufactured of elastic and flexible material. Such a trick scooter is advantageous as it is lightweight, easy and safe to handle and does not damage the surroundings or cause injury to people nearby.

The invention relates to water amusement facilities generating artificial waves for surfing. The technical result is a simpler and lighter design and a shorter assembly and dismantling time along with the capability to control the water flow rate and to stabilize the flow. The above technical result is achieved by the proposed artificial wave generation surfing facility, including a water tank having installed at its upper portion: a working surface having an inclined section and a drainage grille; a submersible pump whose outlet is connected to a water moving device (hydraulic unit), with the hydraulic unit's outlet being positioned above the working surface, the working surface is laid over flooring with a wave generation threshold and the hydraulic unit's outlet is partitioned into sections, the hydraulic unit's outlet has a direct exit channel to the upper edge of the working surface inclined section, while the lower edge of the working surface inclined section makes a smooth transition to the wave generation threshold.

Aspects of the present disclosure involve hydraulic systems and methods for altering a flow of a body of water, such as a river, channel, and/or other flowing or uncontained bodies of water. In one aspect, a hydraulic system provides a velocity barrier for the impedance of aquatic organism migration. More particularly, the velocity barrier may be adapted based on the swimming capabilities of one or more aquatic organisms to impede migration. The aquatic organism may be one or more species of fish, such as species sea lamprey (Petromyzon marinus). The example implementations shown and described herein reference the restriction of the sea lamprey. However, it will be appreciated that other aquatic organisms could be restricted by the presently disclosed technology, for example, with different hydraulic targets depending on swimming capabilities.
