A wave pool for generating surfable waves is disclosed. The wave pool includes a pool for containing water. The pool defines a channel having a first side wall, a second side wall, and a bottom with a contour that slopes upward from a deep area proximate the first side wall toward a sill defined by the second side wall. The wave pool further includes at least one foil at least partially submerged in the water near the side wall, and being adapted for movement by a moving mechanism in a direction along the side wall for generating a wave in the channel that forms a breaking wave on the sill. The wave pool further includes one or more passive flow control mechanisms to mitigate a mean flow of the water induced by the movement of the at least one foil in the direction along the side wall.

A reconfigurable water distribution system for a walk-in tub bathing installation including two or more types of discharge ports for discharging water. The system includes a single motorized pump having an input connected to a suction port of the bathing installation, and an output port delivering pressurized water. A pipe system selectively connects the pump to the two or more types of discharge ports to selectively direct the pressurized water to the different ones of the types of discharge ports. The system selectively enables the bathing installation to perform a plurality of different functions using a single pump.

A surface gravity wave generator and wave pool is disclosed. A wave pool is formed of opposing side walls and a center channel of water. The channel includes a bottom contour with a depth that runs from a deep end to a shoal or beach. One or more three-dimensional foils are vertically arranged along at least one side wall, and moved against the water in the channel. Each foil has a curvilinear cross-sectional geometry that defines a leading surface that is adapted to generate a wave in water moving past the leading surface, and a trailing surface configured for flow recovery to avoid separation of the flow of water in the wave and to mitigate drag from the foil from the water moving past the leading surface.

A capped bathtub system including a bathing well having a rim extending along a perimeter of an upper part of the bathing well and a rim cap configured to cover the rim. The rim cap includes a first flange that extends partially along an inner surface of the bathing well, a second flange that extends partially along an outer surface of the bathing well, and a cover portion that connects the first flange to the second flange. At least one recess is formed into a portion of the rim that is covered by the rim cap.

A method and a system are described for operating a bathing unit system to provide swim-in-place functionality to a swimmer. A communication link is established between the bathing unit system and an auxiliary device worn by or implanted in the body of the swimmer. A signal conveying information associated with the swimmer and originating from the auxiliary device is received. Control signals for controlling operational settings associated with a propulsion assembly of the bathing unit system are derived at least in part by processing the information conveyed by the signal originating from the auxiliary device. The control signals are then released to control the operational settings associated with the propulsion assembly. In another aspect, a graphic display is provided presenting the user with a customized set of selectable swim-in-place configurations derived at least in part by processing a signal originating from an auxiliary device worn by or implanted in the body of the swimmer.

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.
