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.

Swimming goggles are developed to allow a swimmer to see the end of the pool without moving their head while swimming in backstroke. Using a light reflector, a swimmer can see through a backstroke viewing window, allowing them to see along the direction that they are moving when swimming backstroke. Using a motion sensor and electric control circuits, a swimming goggle can provide optimum views for the swimmer wearing the swimming goggle. Using a sound speaker, a swimming goggle can play music and provide voice reports to the swimmer. The electronic controller for a swimming goggle can either be embedded as part of a swimming goggle, or can be detachable to support more than one swimming goggle.

A portable water sports environment is provided. The environment includes a mat positioned on a liner. The front end of the liner may be positioned proximate to a body of water. The back end of the liner may be positioned distally to the body of water. A spray nozzle positioned along a front end of the liner may spray water from the body of water onto the mat and toward the back end of the liner. The environment may a ballast positioned on the top surface of the liner and spaced from the mat. The mat, the top surface of the liner, and the ballast may define a trench that extends away from the back end of the liner and toward the front end of the liner. The trench may guide water received from the spray nozzle toward the front end of the liner and into the body of water.

A swim fin assembly for increasing propulsion during swimming includes a sleeve that is worn around a lower leg while swimming. A plurality of fins is each hingedly coupled to the sleeve. Each of the fins is urged into a deployed position on a downstroke of the lower leg during swimming. In this way each of the fins frictionally engage water thereby increasing thrust generated on the downstroke. Each of the fins is urged into a stored position on an upstroke of the lower leg during swimming to resist frictionally engaging the water thereby reducing drag on the upstroke.

A fin assembly for aqua resistance exercise comprises a strap having an inner strap and an outer strap, and with fastener(s) provided to an outside of the inner strap and an inside of the outer strap to releasably attach the inner and outer straps together. One or more fins are received on the outer strap and a longitudinal position of the one or more fins is secured by engagement of the inner strap to the outer strap. The length of the inner strap is longer than a length of the outer strap, so that an extending end portion of the outer strap can overlap and engage an opposite end of the outer strap to secure the fin assembly about the user's limb.

A timing apparatus for an aquatic timing system includes a rigid and planar primary portion, a flange portion extending at an angle from the primary portion, a vibration sensor coupled with the flange portion, and a controller. The vibration sensor is operable to detect a touch event occurring on the primary portion and respond to the touch event by generating a signal. The controller is in communication with the vibration sensor and is configured to receive the signal from the vibration sensor and identify a touch event from the signal. The vibration sensor may be operable to detect the touch event by detecting a vibration on the flange portion that originated from the touch event on the primary portion.

A timing device is provided herein. The timing device includes a housing defining an aperture in a surface thereof. An elongated member is extendable from the housing. A wheel is attached to an interior surface of the housing. An encoder is operably coupled to the wheel and is configured to calculate a rotational velocity of the wheel. A controller is configured to calculate a linear velocity of the elongated member based on the rotational velocity of the wheel.

A resistance swim training device is described. The resistance swim training device includes a waist harness configured to secure around a waist of a swimmer. The resistance swim training device also includes a spacing bar configured to facilitate moving and rotation motions of the swimmer. The resistance swim training device further includes two or more cords that connect the spacing bar and the waist harness.

To precisely identify a state of an athlete who is present in a swimming pool, a processor used in a device for identifying a state of an athlete or a method for identifying a state of an athlete refers to a result of performing processing of detecting the athlete in a video image obtained by imaging the athlete who is present in the swimming pool and identifies an advancing direction of the athlete as a direction that is different from the previous advancing direction on the basis of a result of the detection of the athlete after the athlete is present in a region on the side of an end of the swimming pool. In this manner, it is possible to more accurately identify the advancing direction of the athlete and to thereby precisely identify the state of the athlete who is present in the swimming pool.

An eye protection system including a reservoir for containing a product, the reservoir securable to a strap of an eye protection system. A spout communicatively coupled to the reservoir, the spout for dispensing the product to a lens of the eye protection system while the reservoir is secured to the strap.
