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 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 jumping actions.

There is provided a swim-in-place spa, comprising a basin for containing water, a circulation subsystem having a primary conduit extending from an inlet in the basin, a pump fluidly connected to the primary conduit to pump water from the inlet, a swim-in-place jet affixed to the basin, and a secondary conduit extending from the pump to the swim-in-place jet, in operation the pump inducing a flow of water toward the swim-in-place jet. The swim-in-place jet has a nozzle and a diffuser downstream of the nozzle relative to the flow of water, a nozzle outlet smaller than a diffuser inlet, the nozzle outlet and the diffuser inlet disposed in a spaced-apart relationship defining a gap for receiving a flow of entrained water. The circulation subsystem is configured for creating a water jet matching a cross-section of a swimmer.

A swimming starting platform having a base supporting a tread surface and an anchor ledge for supporting swimmers. The base includes a shaft extending through an interior cavity of the base from a first side panel to a second side panel. An adjustment mechanism is coupled to an end of the shaft and positioned along the first side panel, where the adjustment mechanism is actuatable to rotate the shaft and adjust a position of the anchor ledge relative to the base of the starting platform.

The invention is directed to improve the body alignment in the water of a swimmer. The head band sits on the back of the head allowing the rod to extend down the back to between the shoulder blades. This limits two motions that are undesirable for efficient swimming of the crawl stroke: inappropriate lifting of the head from the neck and over rotating the neck. This lowered neck position and limited neck rotation forces the swimmer to rotate more from the torso in order to clear the water with their mouth and breath and keep the swimmer in an improved body position.

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 swim lane apparatus having one or more attachment or tethering devices. The one or more attachment or tethering devices are configured to couple or affix to a foundation of the pool. The swim lane apparatus has a first sidewall. The first sidewall is coupled to the one or more attachment or tethering devices. The first sidewall is configured to form a channel and direct a flow of water out of the channel when the flow of water enters the channel.

A wave making apparatus for use with a wave pool having water is disclosed. The apparatus includes a wave making chamber having an interior and a plurality of chamber walls. The chamber also has a passageway connecting the interior to the wave pool and constructed to allow water to flow there between. A water vane is disposed of in or adjacent to the passageway. The wave vane includes at least one smooth and curved water vane wall, which in combination with the plurality of chamber walls, create at least two conduit paths for the water flowing between the interior to the wave pool. The conduit paths have two ends, and the water enters one end at a first direction and exits the second end at a second direction.

A mono-fin for swim training is disclosed. The mono-fin has two separated boot structures that from two separate foot cavities for holding feet with toes positioned in front regions of each of the boot structures and heels positioned at back regions of each of the boot structures. The mono-fin has a mono-fin structure with blades portions connecting the boot structure through the front regions of each of the boot structures. In a middle region of the mono-fin structure and between the blade portions, there is flex region. The flex region allows angles between the boot structures, distances between the back regions of the boot structures and angles between the blade portions to be changed simultaneously by a swimmer while swim training in an aquatic environment.
