  • Patent number: 10233660
    Abstract: A wave pool having a deep end and a shallow end with a plurality of wave generators along the deep end that are extended along a curved stagger line positioned at an oblique angle relative to the moving waves. The wave generators are preferably extended in a substantially staggered manner relative to the travel direction of the waves. A pair of dividing walls is preferably provided in front of each generator, wherein the dividing walls are extended substantially forward with a fade angle of no more than about 20 degrees relative to each other. The wave generators are preferably operated in sequence, such that a plurality of wave segments is generated, and such that the wave segments travel forward and then merge together to form a substantially uniform resultant wave which travels forward and then breaks along the shallow end.

  • Patent number: 10105611
    Abstract: A padded grating system comprising sheets of multiple composite members secured together with multiple support bars or battens, wherein each composite member preferably consists of an elongated rigid bar with a foam layer adhered thereto which are encapsulated by a PVC or plastic water impervious tube or sleeve that has been heated and shrunk thereon. The sheets are specifically designed to be used in connection with water rides such as the FlowRider® and can be modularly installed on site to cover certain drainage areas. The composite members are preferably made by gluing the rigid bars onto a sheet of foam and cutting the foam sheet to form the composite members, and after the tube or sleeve has been heat shrunk around each one, the ends of the composite members are then cut and sealed.

  • Patent number: 9856665
    Abstract: A wave pool for producing waves has a first wave-forming portion with an inclined section for causing the waves to begin breaking and a second wave-dampening portion with a raised floor with perforations extended above a bottom chamber floor. The raised floor is preferably adapted with a predetermined porosity such that a boundary layer of energy absorbing vortices and eddies is generated above and below the raised floor, resulting from water passing up and down through the openings, and the boundary layer effects on the raised floor help to dampen the waves.

  • Publication number: 20160053504
    Abstract: A wave generator for a wave pool with a floating attenuator housed within a caisson compartment that has mass, density and weight characteristics that enable it to remain substantially in contact with the top surface of the water in the compartment. Additional mechanisms are provided which help to keep the attenuator in a substantially horizontal orientation within the caisson, such that unwanted wave motions and water movements within the caisson compartment can be substantially reduced or eliminated. These mechanisms include the adaptation of a vertical post within the compartment and cable and pulley systems that are designed to help control the up and down movement of the attenuator as it travels up and down within the compartment.

  • Patent number: 9144727
    Abstract: The invention relates to a positively buoyant wave generator adapted to travel through a body of water, wherein specific features are incorporated into the wave generator to help create and off-set various hydrodynamic forces that can act on the wave generator as it travels through the water. Rather than eliminating these hydrodynamic forces, the invention seeks to create and counter these forces, which has been found to help keep the wave generator in substantial equilibrium. For example, a connecting member can be extended forward and below the wave generator's center of buoyancy, such that as the wave generator is pulled, it creates an upward force that helps to counter a downward force acting on the front end of the wave generator as water is lifted up. Various internal moments can also be created and off-set by adjusting the center of gravity and/or center of buoyancy and using these forces to help keep the wave generator in substantial equilibrium.

  • Publication number: 20150089731
    Abstract: A wave pool having multiple wave breaking zones extending across the pool floor, wherein different wave breaking formations with different wave characteristics can be generated within each zone, using the same wave energy derived from the same original wave, wherein surfers with different abilities can surf in different locations within the same pool. Specific features are provided that enable breaker waves to be properly managed and controlled such that intermediate/advanced surfers can surf in one zone and beginner surfers can surf in another zone. Included are special dividers to prevent surfers from crossing from one zone to the next, while at the same time, allowing wave energy to pass through. An attenuating means is provided to help reduce the choppiness of the waves.

  • Publication number: 20150065261
    Abstract: The invention relates to a flow divider for a sheet flow water ride having an inclined ride surface capable of dividing it into two or more sections, wherein more than one rider can then safely ride on the water ride at the same time. The water ride can include an inclined ride surface on which a sheet flow of water is propelled that can conform to the contours of the ride surface. The flow divider can be an inflatable tube that can float and extend longitudinally over the sheet flow in the same direction thereof. The flow divider can be secured at its front end to the water ride, and its back end can be relatively free to pivot and shift from side to side. In some embodiments, the air pressure in the tube can be adjusted to enable the divider to be inflated to the appropriate stiffness.
