A waist tethered buoy assembly tethers to a waist belt worn during water activities. The assembly includes a shell defining an interior space wherein the shell is buoyant. A net is positioned around the shell. A cord is coupled to the net securing the net around the shell. A tether has a net end net end coupled to the cord wherein the tether is coupled to the net. A belt is configured for securing around a waist of a user. A belt end of the tether is coupled to the belt such that the shell is configured to be attached to the user.

An adjustable eyewear restraint comprises a first strap having a first adjustment end and a first eyewear coupling end, and a second strap having a second adjustment end and a second eyewear coupling end. The straps are slidably and frictionally engageable to one another to allow adjustment of a length of the restraint by moving adjustment ends of the straps relative to each other. The straps can be slidably interwoven to each other about opening(s) of respective adjustment ends. The opening(s) slidably receive an opposing strap. A strap has a loop, coupleable to eyewear, that comprises first and second edges attached together to form an attachment portion substantially in-line with the first edge. A frictional element is frictionally and slidably coupleable to an earpiece to retain the loop and allow adjustment of a length of an eyewear retainer. Associated systems and methods are provided.

A method of triggering an action includes: determining that a mobile device is under water by: determining that an amplitude of a satellite positioning system (SPS) signal, or a wireless communication signal, or a combination thereof, received by the mobile device is below a threshold amplitude; or comparing data from a motion sensor of the mobile device with motion sensor data characteristic of entering water; or a combination thereof; determining that the mobile device has an action-inducing relationship to water; and taking the action in response to determining that the mobile device has the action-inducing relationship to water.

The present invention relates to a floatable breathing device. The floatable breathing device a head unit, a mask and a snorkel. The head unit general includes an ornamental shaped outer housing, an insulated housing positioned within the outer housing and having an ornamental shape and buoyant properties, and a head receiving section provided between the outer housing and the insulated housing and contoured to a human head. The mask extends from the outer housing, while the snorkel extends through and exits a portion of the head unit above a predetermined waterline.

The present disclosure relates to system and method for real-time tracking and displaying of an athlete's motions. The disclosure includes of a system for tracking the movement of key parts of the human body, then transmitting data acquired to create a visual of the movement of the body within a viewing device. The system includes a plurality of sensor devices attached to various parts of the athlete's body that are configured to collect sensor data about movements of an athlete's body, a controller configured to process the sensor data received from the plurality of sensor devices to generate one or more views of the movements of the athlete's body, and a display module configured to display the one or more views of the movements of the athlete's body.

A training aid for a swimmer includes a housing. The housing is sealed so that the housing is water tight. A coupler is coupled to the housing and is configured to couple to a swimmer's goggles to couple the housing to the goggles. A power module, a microprocessor, and a sensor are coupled to and positioned in the housing. An indicator is coupled to the housing. The microprocessor is operationally coupled to the power module. The sensor and the indicator are operationally coupled to the microprocessor. The sensor is configured to detect motion of the housing so that the microprocessor is positioned to determine a speed of the swimmer and to compare performance values of the swimmer relative to target values. The microprocessor is positioned to selectively signal the indicator to notify the swimmer of a difference between the performance values and the target values.

An Internet of Thing (IoT) device includes a camera coupled to a processor; and a wireless transceiver coupled to the processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

The present disclosure generally relates to providing perceptual notifications containing information about a measured activity-based value of a swim characteristic. In some examples, the perceptual notifications utilize colors and haptic taps to convey measured values of the swim characteristic without requiring the swimmer to interact with the perceptual notification while the swimmer is swimming.

A flotation device, particularly suitable for use as a pull buoy or a kickboard is described. The flotation device can include a flotation element and a stem element, which extends from an inner surface of the flotation element. A holding mechanism can be located adjacent to the second end of the stem element. The stem element and holding mechanism can be configured to enable a user to hold onto the flotation device at a point below the surface of the water for use as a kickboard or enable a user to secure the stem element of the flotation device between his/her legs for use as a pull buoy. An embodiment of the stem element can be tapered, which can create forces that assist the user in using the flotation device as either a pull buoy or a kickboard.
