A magnetic swimmer restraint device including a magnetic cone assembly, a strap assembly, a bracelet remote assembly, and a pool assembly is disclosed. These assemblies in conjunction with one another provide a user with a portable restraining system for increased resistance swimming. A wearable strap assembly interacts with magnetic cone assembly that can be located on the lateral sides of a pool or in the pool itself. As a user swims past the magnetic cone assembly the wearable strap assembly becomes magnetically attracted to the magnetic cone assembly. The magnetic attraction of the strap assembly worn by the user to the magnetic cone assembly pulls the user towards the magnetic cone assembly. Thereby increasing swimming resistance. The magnet of the magnetic cone assembly may be an electromagnetic system to be turned on and off via a bracelet remote assembly.

Automatic swimming analysis and nearly immediate feedback on a user device is disclosed. A sensor placed on a swimmer's waistline instantaneously measures data of the swim, allows to upload this data to a cloud system performing immediate analysis using algorithms. The cloud system provides feedback which helps determine proper (or improper) swimming techniques, comparing patterns to own past swims or to professional swimmers. The sensor enables stroke improvement with output including graphs, single numerical values, and detailed single-stroke data. The output provides both easy to understand metrics for amateur swimmers as well as more technical analysis options for advanced users. Metrics for amateurs can include swim symmetry analysis, speed consistency analysis, and stroke consistency analysis. More technical/detailed information includes comparison of strokes of each arm to the other, comparison of strokes made by left and right arms, mathematical analyses of strokes, and average, maximum, minimum, and instantaneous speeds.

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 countercurrent swimming system for swimming pools or swimming baths comprises a housing box which has at least one water inlet opening and at least one water outlet opening, a propeller for generating a water flow, which propeller is arranged in a flow channel, the flow channel opening into the at least one water outlet opening downstream of the propeller and hydraulically communicating with the at least one water inlet opening upstream of the propeller, a drive motor for the propeller. The countercurrent swimming system includes the drive motor arranged outside of the housing box and in that the propeller and the drive motor are coupled to one another via a magnetic coupling.

A variety of improvements to portable electronic devices are disclosed, particularly electronic devices designed for use in and around water. The improvements include a more secure interface jack, improved waterproofing techniques, improved battery stability, and improved device functionality. One or more of the disclosed improvements may be incorporated into a variety of portable electronic devices.

A swim in place system and method are provided. The system comprises a swim in place pool, at least one sensor, at least one pump associated with said at least one sensor, at least one processor, and a memory comprising instructions which when executed by the at least one processor configure the at least one processor to perform the method. The method comprises receiving object location data from at least one sensor, and actuating the at least one pump associated with the at least one sensor when the object is positioned inside a set perimeter within said swim in place pool. The object positioned in a swim in place pool.

A swim training device includes: (a) a platform having a top side and a bottom side, and extending longitudinally from a leading edge to a trailing edge and extending laterally from a left side to a right side; and (b) a hands pocket located on the top side of the platform and including a hands entry opening facing toward the trailing edge of the platform, wherein: (i) the hands pocket is constructed to receive a user's hands through the hands entry opening so that the user's hands are located in the hands pocket in a generally extended configuration; (ii) the hands pocket is constructed to hold the user's hands in place in the generally extended configuration against the top side of the platform; and (iii) the hands pocket is constructed to resist longitudinal and lateral movement of the user's hands relative to the platform when the user's hands are located within the hands pocket.
