A system can be used for detecting execution of a swimming activity of a user. The system includes a processing unit, a buffer, and an electrostatic-charge-variation sensor configured to sense a variation of electrostatic charge of the user during execution of the swimming activity and to generate a corresponding charge-variation signal. The processing unit is configured to acquire the charge-variation signal, detect a first sub-portion of signal that identifies a basic movement of the swimming activity in the charge-variation signal, store the first sub-portion of signal in the buffer, compute an auto-correlation between the first sub-portion of signal stored in the buffer and a second sub-portion of signal of the charge-variation signal, and detect the presence of the basic movement in the second sub-portion of signal based on a result of the auto-correlation.

The ATPU includes the first electronic communications channel for receiving the measured data from the ATMU, a microprocessor, a memory storage area, a database stored in the memory storage area, and a tracking processing module located in the memory storage are. The database stores a first set of evaluation rules and a second set of evaluation rules, the first set of evaluation rules corresponding to one or more tracking parameters, and the second set of evaluation rules corresponding to the one or more apparatus conditions. The tracking processing includes program instructions that, when executed by the microprocessor, causes the microprocessor to determine the one or more tracking parameters using the measured data and the first set of evaluation rules, and determine the one or more apparatus conditions data using the one or more tracking parameters and the second set of evaluation rules.

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 buoyant outer material and an inner shell positioned within the buoyant outer material. The inner shell forms a head receiving section and a protruding section. The head receiving section is received internal to the buoyant outer material and is configured to be contoured to a human head, the protruding section extending from the head receiving section to a vent opening in the outer buoyant material. The snorkel is connected to and extending through the head unit, while the plurality of receiving passageways are disposed about the inner shell and receiving the snorkel such that the snorkel extends through and exits a portion of the head unit at the vent opening. The internal pathway is positioned along a base of the outer buoyant material and extends between the internal shell and the buoyant outer material, passing to the interior of the interior shell through a cutout in a protruding portion thereof and terminating adjacent to the vent opening.

In accordance with embodiments disclosed herein, there are provided systems, methods, and apparatuses for implementing a GPS directional swimming watch for the eyesight impaired. For example, according to one embodiment there is a wearable navigational apparatus including: a mechanical input to receive coordinates for a first location located at an end of a first fixed segment originating from an starting point in a first single cardinal direction; a mechanical input to receive coordinates for a second location located at the end of a second fixed segment originating from the first location in a second single cardinal direction perpendicular to the first cardinal direction, in which the first and second fixed segments form a selected route; a haptic feedback motor having a magnetized compass integrated therein to signal a wearer directional information relative to the first and second locations set, in which the hepatic feedback motor signals the wearer to change direction upon any of: (i) reaching the first location, (ii) reaching the second location, and (iii) deviating from any point along the selected route during bidirectional navigation; and a return function to signal to the wearer, via the haptic feedback motor, directional information relative to the starting point from any point along the selected course. Other related embodiments are described.

A multi-camera system for multidimensional video capture is particularly useful for recording the movements of swimmers. The system includes a self-propelled mobile frame that is of sufficient size to surround a swimmer while he or she swims. The frame carries a number of equipment pods. Each equipment pod houses cameras, typically a pair of stereocameras, and may house additional sensors as well. Propulsion pods connect the frame to a pair of tracks, one of which is on each side of the frame, and propel the frame along the tracks. The frame may also support one or more booms that carry equipment pods with cameras and allow the system to capture video from additional angles. The frame carries transmission hardware allowing it to communicate video and other data to external receivers and communication devices in real time or near real time, and to receive data from external devices.

The present invention provides for an apparatus and a method for maintaining the position of a swimmer's legs and limiting the range of motion of the swimmer's knees when swimming.

The present invention relates to a swimming assistance mechanism and, more specifically, to a swimming assistance mechanism that is attached to the arms and increases a propulsion effect by increasing resistance against water via an action like that of the fins of a fish when paddling with the arms for propulsion, so as to assist in enabling easier swimming. The swimming assistance mechanism of the present invention is characterized by comprising: a main body fixed between the palm and the elbow; and a fin foldably installed on the outer surface of the main body.

A swim fin may include a foot pocket configured to receive a foot of a swimmer and a fin blade extending from the foot pocket. A relatively rigid substrate chassis may be bonded to the foot pocket. The fin blade may be relatively flexible. Fin rails may extend along the lateral edges of the fin blade. The fin rails may include a fin spine comprising a plurality of fin spine segments in linear configuration. The fin spine may be configured to provide a swim fin with predetermined hydrodynamic characteristics. The swim fin may flex within a maximum angle of attack that may be variable and dynamically changed, within a predetermined maximum attack angle range, as a function of the kicking force generated by a swimmer during a kicking cycle.
