In a competitive athletic event the disclosed signaling system provides for visually signaling of participants, for example, a lane specific visible indication to begin a race. A sequence of light colors is used to signal the start of a race, and is believed advantageous over an audible start signal, particularly for athletes who are hearing impaired.

Swimming goggles have a left-eye covering and a right-eye covering, each having a corresponding transparent window that defines a field of view and each further having a seal extending between the transparent window and the swimmer's face and formed to exclude water. A near-eye display is in signal communication with an image processor and forms a virtual image in the left- or right-eye field of view.

The present invention is a tethered resistance swim training apparatus with a pulley that includes an electronic tachometer to measure the rotations of the wheel of the pulley and strain gauge to measure the force pulling on the body of the pulley. The pulley, also referred to as “smart pulley”, can be implemented in many tethered swim training apparatuses of different arrangements. With the tachometer and strain gauge the power and other performance metrics can be calculated while a swimmer is using the apparatus. A load cell or similar can be used in place of a strain gauge. The sensors may be connected via wired or wireless communications to a computer (tablet, laptop, personal computer, server, or the like) for processing of the signals and display on an electronic display.

An aquatic training aid includes a paddle member for wearing by a swimmer, a variable diaphragm disposed within the paddle member, the variable diaphragm including a plurality of fitted blades arranged to form an aperture, and a housing peripherally framing the plurality of fitted blades. The variable diaphragm is adjustable to change the aperture from a first expanded position to a second contracted position, and hydrodynamic characteristics of the aquatic training aid when moved through water are affected by the change of the aperture. Controlling the aperture enables the swimmer to adjust the resistance provided by the aquatic training aid when it is moved through water.

A smart vehicle flock navigation system includes a plurality of smart vehicles configured to follow a leader smart vehicle, wherein the leader smart vehicle is configured to follow a target vehicle or a target driving plan; each smart vehicle being equipped with: obstacle detection and avoidance capabilities; vehicle-to-vehicle communication means for transmitting information about obstacles and evasive actions to following smart vehicles; a flock control module for adjusting the driving path of the smart vehicle flock based on transmitted obstacle information; a flocking behavior algorithm based on three independent rules: Separation, Alignment, and Cohesion, controlling the motion of each smart vehicle within the flock; and a distributed flocking operation mechanism utilizing wireless network communication for coordinating the behavior of the smart vehicle flock.

Systems and methods for electronically providing fitness activity feedback to a user are disclosed. The method may include collecting performance data, generating comparison data by comparing the respective performance and including identifying comparison performance data representative of performance differences, and displaying the comparison data and the comparison performance data.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

An apparatus and method for swim training are disclosed herein. In one embodiment, a cable is secure to a starting block or other fixed object at or near the edge of a pool, and the cable is then extended into the pool. The cable includes, along its length, fixed securement points to which multiple swimmers may be secured, via belts worn by the swimmers, to the cable. Because the swimmers are secured to fixed positions along the cable, multiple swimmers may swim in the same lane without interfering with each other. In another embodiment, the cable may be secured at both ends of the pool.

A wearable device for tracking swim activities of a user is provided. The wearable device may include one or more sensors configured to generate sensor data, and based on the sensor data, the wearable device may determine swim metrics such as swim stroke count, swim stroke type, swim lap count, and swim speed. The determined swim metrics may be filtered based on one or more swim periods during which the user is likely to have been swimming. The wearable device may determine such swim periods based on the sensor data and/or the determined swim metrics.

The present invention relates to a floatable breathing device. The floatable breathing device provides includes a head unit, a snorkel, a plurality of receiving passageways, and an internal pathway. The head unit has buoyant properties and includes an ornamental shaped outer housing and an inner housing positioned within the outer housing, the inner housing forms a head receiving section, the head receiving section is provided between outer surfaces of the outer housing and is configured to be contoured to a human head. The snorkel connects to and extends from the head unit. The plurality of receiving passageways are disposed about the outer housing and receiving the snorkel, the snorkel extending through and exiting a portion of the head unit above a predetermined waterline extending along a periphery of a lower portion of the head unit thereof and identifies buoyancy of the head unit in water. The internal pathway positioned along a base of the outer housing and extending through a center section of the head receiving section of the head unit.
