This invention is embodied by a controlled, variable tension line, payout reel machine. A system of sensors detect line tension and line distance paid out, location, and transmit through wired and unwired communication to a microprocessor. The microprocessor is co-located with the reel structure, which in turn applies, via a brake feature, resistance to the reel which is paying out the line being pulled by the user. This invention pertains to all applications where it is desirable to control the tension in a line paid out from a reel or reel. As stated, the payout motive force is supplied by the person, animal or apparatus attached to the end of the line, opposite the reel. The invention applies to the field of precise and measured control of line tension for sport, sport training, performance testing.

The disclosure herein provides a golf GPS device with a sensor mechanism to automatically switch between video and audio only modes of the device. More particularly, when a player attaches the golf GPS device to a piece of clothing or hat, the device automatically switches to audio-only mode. When the player detaches the golf GPS device, the device automatically switches to video mode, with or without audio. The golf GPS device further includes one or more processors configured to repeatedly determine in which one of the plurality of holes the device is located, to repeatedly compute a distance between the device and a feature of the determined hole, and to cause to display the hole number of the determined hole and the computed distance on the display screen.

An exercise and therapeutic device includes a treadmill comprising a running belt coupled to a treadmill frame and an offloading system coupled to the treadmill. The offloading system includes an air chamber surrounding the running belt adapted to be selectively inflated between a deflated condition and an inflated, operating condition, a user seal coupled to the air chamber, adapted to receive a user so that, in an operating condition, at least a portion of a user is received in the user seal and positioned within the air chamber and to seal the air chamber around the user, a pump operable to inflate the air chamber, at least one strap coupled to the treadmill frame and adapted to restrict the expansion of the air chamber and adjust a spacing of the user seal relative to a running surface of the running belt when the air chamber is inflated.

An adjustable laser-sensor paired system for creating or replicating a desired swing form includes a laser device and a sensor device. The laser device has a laser which emits a laser beam and a mounting device which attaches the laser device to an object. The orientation of the laser is adjustable. The sensor device has an optical linear position sensor for detecting the laser beam of the laser device and a display with LEDs for providing feedback and user interface. With the system and method, one or more checkpoints for the form of a desired swing can be created at a selected point in the swing path, which may then be used as practice reference guides to check whether the user is correctly replicating the desired swing.

A self-powered apparatus is used for various kinds of cycling and indoor exercise devices. The self-powered apparatus includes a pedal unit, a spindle, a generator and an energy storage element. The pedal unit includes an inner surface to form an accommodating space therein. The spindle is accommodated in the accommodating space. The generator includes a stator and a rotor. The stator is disposed on the spindle, the rotor is disposed on the inner surface of the pedal unit, and the rotor surrounds the stator correspondingly and is non-contact with the stator. The energy storage element is electrically coupled to the generator. When the pedal unit is being pedaled to rotate by a rider, the stator is fixed on the spindle, the rotor rotates relatively to the stator and along with the pedal unit, and a power is generated by the generator to charge the energy storage element.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.

Disclosed embodiments include a multi-mode sensor including an elastomeric strand having a first multi-mode sensing region configured to sense at least two different physical parameters, and a second multi-mode sensing region, space apart from the first multi-mode sensing region, and configured to sense at least two different physical parameters. In some disclosed embodiments the first multi-mode sensing region is configured to measure the physical parameters of angular displacement and strain.

A walking training system includes a treadmill, a center-of-gravity position detection unit that detects a center-of-gravity position of a trainee from a load received from a sole of the trainee on a belt of the treadmill, a posture detection unit that detects a posture of the trainee, a center-of-gravity position estimation unit that estimates the center-of-gravity position of the trainee from the detected posture of the trainee, a determination unit that determines whether a difference between the detected center-of-gravity position and the estimated center-of-gravity position exceeds a predetermined value, and a notification unit that sends, when the determination unit determines that the difference exceeds the predetermined value, a notification notifying that whether the difference exceeds the predetermined value.

A walking training device according to the present embodiment includes: a robot leg attached to one leg of a trainee; a treadmill; a load distribution sensor that detects a distribution of a load received from a sole of the trainee riding on the belt of the treadmill; and a walking state determination unit that determines whether the one leg has switched from a standing state to a swinging state based on a state of increase in a load detected by the load distribution sensor and received from another leg of the trainee performing walking training; and a control unit that starts bending control for the swinging state of the robot leg when the walking state determination unit determines that the one leg has switched from the standing state to the swinging state.

A balance training system including a riding plate; a load distribution sensor; a load sensor; a mobile body on which the riding plate, the load distribution sensor, and the load sensor are disposed; and a control unit configured to calculate a reference position based on positions of feet of a trainee detected by the load distribution sensor, then calculate a center of gravity position of the trainee based on the load detected by the load sensor, and control a movement of the mobile body based on a change of the center of gravity position with respect to the reference position. The control unit is configured to update the reference position based on the changed positions of the feet of the trainee when the change of the position of at least one of the feet of the trainee is detected by the load distribution sensor.
