A hand control device for swimmers is presented. The device has a main body with two holes in a side-by-side configuration. The first one of the two holes is configured for a third digit of a person's hand while the second one of the two holes is configured for a fourth digit of the person's hand. The inside surface of each hole comprises a plurality of grooves that run depthwise thereby providing wet traction while impacting minimum direct pressure on the nerves, vessels and tendons. The outside surface of the device may also include ridges to provide pass through for water.

This disclosure relates to systems, media, and methods for providing near-instantaneous feedback from real-time motion sensor data. In an embodiment, the system may perform operations including loading at least one target motion trigger. Disclosed embodiments may receive real-time sensor data from the first motion sensor detachably fixed to a user. Additionally, disclosed embodiments may include calculating a motion profile based on the real-time sensor data, the motion profile describing a multi-dimensional representation of acceleration of a motion performed by the user. Disclosed embodiments may also include comparing the at least one target motion trigger to the calculated motion profile to determine if the motion performed by the user corresponds to the target motion. Further, disclose embodiments may include transmitting, based on the comparison, an instruction to provide an alert to a user.

A swim paddle can include a low profile housing body including a hand surface and a water surface. The low profile housing body can further include a longitudinal axis that is parallel to the length of a hand of a swimmer and a transverse axis that is parallel to a width of the hand, wherein the longitudinal axis is longer than the transverse axis, and wherein the hand surface is adjacent to a palm of the hand. The paddle can further include a strap that can secure the low profile housing body with the hand of the swimmer. The swim paddle can further include an electronics package that can be affixed to the low profile housing body.

The present disclosure relates to systems and methods for elastic delivery, processing, and storage for wearable devices based on system resources. For example, a wearable apparatus may have at least one battery; at least one sensor configured to measure at least one property associated with a user of the wearable apparatus; at least one memory storing measurements from the at least one sensor and instructions; at least one transmitter configured to send data to a device remote from the wearable apparatus; and at least one processor configured to execute the instructions to: receive, from the at least one battery, an indicator of a charge; and based on the received indicator, sending a command to the at least one sensor to operate in a low-power mode or a high-power mode, the low-power mode having. a lower sampling rate than the high-power mode.

A system and method for two swimmer wings designed using biomimicry and inspired by winged creatures/birds of flight as well as the fore flippers of a sea turtle. The swimmer wings are designed for users to traverse long distances instead of relying on personal watercrafts or boats to not only help sustain the environment by reducing the carbon footprint but also provide physical exercise to improve the user's well-being. The swimmer wings include a board, an arm guard which shields the user's forearm, and arm fasteners that secure the user's forearm between the board and the arm guard.

A method of coupling a boot toe body to a fin apparatus is disclosed. The fin apparatus includes a fin body coupled to a boot coupling body. The method involves connecting a first boot connector on a first end of the boot coupling body to a first complementary boot connector on a top side of the boot toe body, and connecting a second boot connector on a second end of the boot coupling body to a second complementary boot connector on a bottom side of the boot toe body. Boot toe bodies, fin apparatuses, and systems including the boot toe bodies and fin apparatuses are also disclosed.

A swim training apparatus for use as a monofin for bilateral undulation power development. The apparatus includes a flexible, elongated member having a series of securing members, such as through-holes extending from the top surface of the elongated member through to its bottom surface, and fasteners configured and disposed to attach to the securing member, such as straps that can extend through the through-holes, to fasten the apparatus to a user's legs. A weight can be attached using similar attachments and fasteners to the apparatus to increase undulation during use.
