A resistance system is disclosed. The resistance system has a line reel system for deploying a tension line and a power system for drawing in the slack line. The resistance value can be set by a subject using the device by using a resistance controller and indicator located on an outer surface of the system. The system can be self-contained with an internal power supply. The system is particularly useful for swim training or rehabilitation. It can be simply operated by a user without removing the device.

A modular and dynamic force apparatus for adjusting standard and dynamic torque-to-linear forces during physical activity in real-time, the apparatus including a force module, a user device and an apparatus tracking processing unit. The force module includes an open hub attachment point, wherein the open hub attaches the apparatus to an external source, one or more sensors measuring data for physical activity efficiency, an internal processor, wireless radio and force sensor module, a variable length cable, a force generating component, and motor controls. The internal processor, wireless radio and force sensor module includes an apparatus tracking measurement unit (“ATMU”) adapted to measure data, a first electronic communications channel for transmitting the measured data to an apparatus tracking processing unit (“ATPU”), and a second electronic communications channel for transmitting one or more apparatus conditions data to adjust dynamic forces. The user device receives one or more apparatus conditions data over the second electronic communications channel for real-time notification and/or adjustments to the user. The user interface includes a display that provides feedback and an apparatus tracking processing unit (“ATPU”). 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.

Provided herein are systems and devices for detecting the position of an object (e.g., a swimmer) within a pool and adjusting the rate of flow produced by an swimming flume system to maintain the object's position within the pool.

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.
