A hydrofoil simulator structure comprising a tank, in which a water current is generated, and a frame, which supports an elastic trampoline positioned above the water surface of the tank; the structure also comprising a series of elastic ropes associated with a trapeze harness worn by a user who stands on a board of a hydrofoil having wings immersed in water.

A system for restricting user movements in an aquatic medium relates to swimming systems and may be used for virtual reality (VR) simulation systems. By using the system, a swimmer returning force may be produced in response to the swimmer movement in any direction, the effect of presence in a VR may be increased, and requirements to the supporting portion and to the surface area of a zone utilized in a swimming pool may be reduced. The system comprises a flexibly resilient member retaining a swimmer (directly or via an intermediary) and anchored by means of a system of supports. The swimmer movements cause the resilient member to move in its entirety, without being deformed, such that its end elevation varies. The system responds by the resilient member flexing to the swimmer displacement in a horizontal direction. To provide for a vertical freedom, the resilient member is mounted on supports configured to rotate. Alternatively, the resilient member is configured to move translationally. The resilient member may be connected to a swimmer via a module secured on the swimmer's body or hand-held by the swimmer. The resilient member may have a curved shape to prevent it from colliding with the user.

A Exercise Pool is disclosed herein having a rigid frame modular in design to allow for improved delivery and assembling. As shown the system may be configured with a box like structure providing containment of the flow head and may be configured with a removable deck having an air gap built in. As disclosed the treadmill swimming pool system as its general configuration is safer for users as it inhibits and/or eliminates hair and body entrapment. As disclosed it has a balanced flow which better replicates or reproduces actual swimming conditions for an enhanced user experience. The propulsion system may be controlled with a variable frequency drive (VFD) to allow for improved swimming conditions and control of same.

A torque measurement system and method for providing real time tracking and motor control for adjusting standard and dynamic torque-to-linear forces in an electromechanical motor. The system includes sensors for measuring data, load wedges affixed to a rotor, a slip bearing for measuring forward and reverse forces of the rotor section, a tracking measurement unit adapted to measure raw data, a wireless radio, an internal processor, and a tracking processing unit.

A pool vision system may include a camera and a controller. A method of controlling equipment of a swimming pool or spa using the pool vision system may include receiving visual data from the camera having a field of view including the equipment and identify the equipment in the visual data and determining an operational state of the equipment based on the visual data. The method incudes comparing the determined operational state of the equipment with an expected operational state of the equipment and generating a control response based on a difference between the determined operational state of the equipment and the expected operational state of the equipment.

An adjustable attachment structure for a swimming machine is disclosed. The attachment structure is configured to interact with a frame of a pool. A user may interact with a locking switch to transition the attachment structure between a locked and an unlocked state. In the unlocked state, the swimming machine may be rotated about an axis to direct a generated current in a number of directions.

Systems and methods for detecting gestures of a swimmer in an aquatic environment such as a flume pool. In one embodiment, a pool system includes a set of cameras, one of which is an overhead camera positioned above the water in the pool to capture images of a swimmer. The system also includes computer processors, such as a GPU, CPU, and game engine which implement a computer vision platform. The processors are configured to receive images from the cameras, determine the swimmer's body position from the images, detect a defined gesture in the swimmer's body position, and in response to detecting the defined gesture, invoking a corresponding control operation of the flume pool, such as controlling water flow through the pool or updating an interface display which is projected onto the interior surfaces of the pool.

The invention relates to a hydraulic pump (10) comprising a pump shaft (52) and a casing (46) delimiting a liquid circulation duct (44) in which the cross-section of the outlet orifice (12) is flattened and is oriented such that the liquid outlet direction (14) is inclined from a longitudinal axis (22) of the pump shaft passing through the casing, the casing comprising a first segment (100a) in which the inside surface (102a) has a circular cross-section centred on said longitudinal axis (22) and surrounding a pump impeller (60) supported on the pump shaft (52). According to the invention, the first segment (100a) has a downstream end starting from which the cross-section of the casing inside surface becomes flattened.
