A self-propelled personal flotation apparatus provides a motorized flotation board which includes internal water propulsion equipment and associated push-button controls. In use, a user straps the apparatus onto their chest area, enters a body of water such as a lake, a pond, or a pool, and is propelled across the water surface.

There is provided an image processing device to enable a user to experience a VR space in a floating state, the image processing device including: a wall configured to form a water storage space; and an image generating unit configured to generate a stereoscopic view image to be displayed on the wall toward an inside of the water storage space.

A wearable computing device that is secured or attached to a resilient strap, the resilient strap sized to fit around at least a part of a circumference of a human head. The device has a waterproof storage volume housing a plurality of sensors. The wearable computing device may calculate a plurality of swimming metrics based at least partly on data received from the at least one sensor. The wearable computing device may include a wireless communication subsystem secured to the resilient strap within the waterproof storage volume and may transmit at least one of the calculated plurality of swimming metrics to at least one computing device via the wireless communication subsystem. The wearable computing device may include at least one user output component and may present an indication of at least one of the calculated plurality of swimming metrics at the at least one user output component for communication to the user. The indication may be audio played in an ear piece connected to the strap, or may be visually displayed on a display in an eye goggle portion of the strap.

A swim paddle training device is provided. The swim paddle may include opposing upper and lower sides or surfaces; front, rear, left, and right edges extending between or bounding the upper and lower sides; and a plurality of surface features arranged to facilitate proper movement of the swim paddle during swim training. The plurality of surface features may create areas of varying buoyancy to affect the orientation of the swim paddle during swim training, such as promoting a forward, downward, and inward pathway or rotation of the swim paddle during use. The plurality of surface features may include a plurality of grooves defined within at least the lower surface of the swim paddle.

There is provided a device and a method of operating the device for determining whether the device is immersed in a fluid. An acceleration signal for the device is acquired (302) and a pressure within the device is detected (304). It is determined whether the device is immersed in a fluid based on a comparison of the acquired acceleration signal with the detected pressure (306).

A hydrotherapy apparatus comprises a tank, the tank comprising a panel arranged to form a wall of the tank, and an inner frame arranged to have the panel mechanically fixed to an outer side thereof, without bonding, so as to form a watertight seal. The inner frame may comprise a lower portion in a base region of the tank and two struts extending upward therefrom. The tank may further comprise a lower fixing section arranged to be mechanically connected to an outer surface of the lower portion of the inner frame, with a lower edge region of the panel therebetween, and two side fixing sections extending upward and each arranged to be mechanically connected to an outer surface of a respective strut of the struts of the inner frame, with a respective side edge region of the panel therebetween.

A floating physical therapy device includes a frame and a harness. The frame includes an inner frame and an outer frame on the right and left side. The inner frame defines a patient area. The harness is attached to the inner frame such that it secures a patient to the device in a substantially upright position during use. The frame extends forwards and backwards, as well as to the left and right, of the patient area in order to provide stability in the water during normal use. The frame defines a trainer area immediately forward of the patient area where a therapist can have access to the patient during therapy sessions.

The invention relates to a surfing installation (10, 10A, 10B) for generating a surfable wave (60), comprising an inclined ramp (50) to the upper end (51) of which water flows via a water inlet (46), which water is accelerated on the ramp (50) to a first flow speed, the lower end (52) of the ramp (50) leading into a region (30) having a lower second flow speed relative to the first flow speed, and a standing wave, in the flow direction, forming in the region (30) as a result of the water flowing at the first, faster flow speed striking the water flowing at the second, lower flow speed. A further functional area for the surfing installation (10) for one or more surfers (80) is achieved, according to the invention, in that at least two walls (506, 508) that define at least one flow channel (504) are arranged in the region of the water inlet (46) and/or of the ramp (50), which walls are movable in rotation and/or in translation, transversely to the flow direction of the water, by means of at least one drive (5046), in order to generate at least one traveling wave (60) that travels transversely to the flow direction.

Wearable electronic devices that are designed to be worn on the head of a user while the user is swimming can determine swimming strokes and swimming performances of the user accurately using motion sensors. Using a sound speaker, the wearable electronic device can play music and provide audio feedback to the swimmer. By comparing the swimming performance of the swimmer wearing the device with previously recorded swimming data, the wearable electronic device can provide audio comparison results to the swimmer while the swimmer is swimming in water. The wearable electronic device can also support similar functions for other sports and physical activities.

A kickboard has a non-planar shape and comprises a primary panel with opposite support members laterally outside from the primary panel with a transitional section therebetween. The support members are at a rear longitudinal position and additional support shoulders may extend from a forward end of the primary panel along each lateral side to a respective support member. The rearward end defines an opening with a cavity formed between the primary panel, transitional sections, support shoulders and support members. In use, the kickboard provides substantially improved ergonomics and allows a swimmer to support her elbows on the support members with a portion of her forearms on the support shoulders, with arms in a bent position below the surface of the water. The configuration improves comfort while maintaining a favorable hydrodynamic swimming position and reducing shoulder stress.
