A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a brake that is structured to apply a selectively variable resistance against rotation of the shaft relative to the structural frame. A FEPS (flexion extension pronation supination) device includes: a structural frame; a shaft mounted to rotate relative to the structure frame; and a gripping member mounted to the structural frame and structured to adhere to an external support surface. A method includes operating the FEPS device by rotating the shaft.

A soft-inflatable exosuit for knee rehabilitation is fabricated in two different beam-like structures (I and O cross-section actuators) and mechanically characterized for their torque performance in knee-extension assistance. The fabrication procedure of both types of actuators is presented as well as their integration into a light-weight, low-cost and body-conforming interface. To detect the activation duration of the device during the gait cycle, a soft-silicone insole with embedded force-sensitive resistors (FSRs) is used. In evaluation studies, the soft inflatable exosuit device is tested for its ability to reduce muscle activity during the swing phase of the knee. Using sEMG (surface electromyography) sensors, the rectus femoris muscle group of a healthy individual is recorded while walking on a treadmill at a constant speed, with and without the soft device.

A treadmill system includes a deck, an endless tread belt covering at least a portion of the deck, a position sensor that senses a position of a user when the user is on the tread belt, and a control module that adjusts a speed of the tread belt in response to an output of the position sensor.

A walking training apparatus 1 includes a leg robot 2 attached to a leg of a walking trainee, a motor 261 configured to rotationally drive a knee joint 22 of the leg robot 2, a control unit 332 configured to control the motor 261 so that the motor 261 rotationally drives the knee joint 22 in a leg-idling period in a gait motion of the walking trainee, a motor torque detection unit 262 configured to detect a motor torque, the motor torque being a torque generated by the motor 261, and a determination unit 333 configured to determine whether or not the walking trainee is in a spasticity state or a rigidity state by using a value of the motor torque detected in the leg-idling period by the motor torque detection unit 262.

A resistance sensing mechanism including a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a screw nut threaded onto the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a first linkage pivotally connected with one end to the screw nut, a second linkage having one end pivotally connected to an opposite end of the first linkage and an opposite end pivotally connected to the locating sleeve, a sensor mounted at one of the first and second linkages and a sensible member mounted at the other of the first and second linkages to face toward the sensor. Subject to the linkage relationship between the first and second linkages, the distance between the sensor and the sensible member can be changed, thereby generating a relative sensing signal.

A resistance sensing mechanism includes a resistance adjusting unit including a holder frame, a locating sleeve disposed above the holder frame, an adjustment screw rod rotatably inserted through the locating sleeve and a first screw nut threaded onto a first thread segment of the adjustment screw rod and pivotally connected to the holder frame, and a sensor unit including a linkage pivotally connected to the holder frame, a second screw nut threaded onto a second thread segment of the adjustment screw rod and pivotally connected to the linkage, a sensor mounted at one of the holder frame and the linkage and a sensible member mounted at the other of the holder frame and the linkage to face toward the sensor. Subject to the relative movement between the first and second screw nuts, the holder frame and the linkage relatively biased to change the distance between the sensor and sensible member.

An example exercise tracker includes a grip for receiving an adjustable amount of exercise resistance, a force sensor having one or more strain gauges programmed to output a force signal representing a force applied to the grip, and a motion sensor programmed to detect movement of the grip and output a motion signal. The exercise tracker further includes a processor programmed to receive the force signal and the motion signal and determine, from the force signal and the motion signal, exercise data including the amount of resistance applied to the grip.

The present invention comprises a unique system and method for providing adaptable ball delivery and tracking, including appropriate sensor hardware, interactive gameplay user interfaces and point of sales systems. The system and method of the present invention are especially relevant to baseball and softball as, among other components, the system comprises a vertical, ground-up soft toss ball delivery mechanism, automated player and ball-tracking devices, and ball-collection and transport systems. The ball collection and return components eliminate the need for “fielders” and enable the creation of the first “batting range”. The vertical, ground-up soft-toss pitch machine further enables the first multi-story batting facility with player batting bays that open onto a sports field. Further, certain embodiments of the present invention integrate hitting screens, augmented reality display and simultaneous coordination of gameplay and communication between players, regardless of the players' physical location.
