A mute self-generating power generator comprises a stator power generation armature and a rotor excitation magnet. The armature extends in a direction towards the magnet to form a plurality of cylindrical induction magnetic poles, and windings are wound on the poles; the magnet comprises at least two layers of structures in a direction towards the armature, one of which consists of a non-magnetic conductive material, and the other layer is formed by alternately arranging ferromagnetic material excitation magnets and magnetic conduction material magnetizers in a circumferential direction; a combination ratio of the number of the ferromagnetic material cylindrical induction magnetic poles and the ferromagnetic material excitation magnets on the magnet meets a double three-phase power generation condition. The generator eliminates the root cause of vibration and noise from the principle, so that it works in a mute state, and can well meet use requirements of various fitness equipment.

A fan vehicle includes a driving wheel, a wind resistance wheel, a resistance unit and a power generating unit. The driving wheel can be driven by two pedals. The wind resistance wheel is connected to the driving wheel via a transmission unit in order to rotate synchronously. The resistance unit includes a mandrel, a flywheel installed on the mandrel and connected to the transmission unit, a magnetic ring mounted onto the flywheel and a magnet securement rack installed on the outer perimeter of the flywheel. One side of the magnet securement rack includes a plurality of magnets. The magnet securement rack can be pulled by a cable in order to change the distance of the magnets relative to the magnetic ring in order to adjust the magnitude of the magnetic resistance. The power generating unit is installed inside the flywheel.

A treadmill includes a frame; a rotatable element coupled to the frame; a running belt at least partially supported by the rotatable element; and, a first element and a second element, both of which are coupled to the running belt. The running belt includes a running surface, at least a portion of which is curved. Further, one of the first and second elements and the running belt freely rotate in a first direction of rotation relative to the frame. However, in a second direction of rotation, opposite the first direction of rotation, the one of the first and second elements is substantially prevented from rotation relative to the frame to substantially prevent or resist rotation of the running belt relative to the frame.

A wearable device such as a garment is disclosed, having at least one sensor, for sensing a parameter. Electronics are provided for processing the sensed parameter, and for providing feedback. Feedback may be in the form of proprioceptive tactile or audible feedback, or in the form of an adjustment of a performance parameter of the wearable device. In one implementation, the processor is configured to activate an effector to provide feedback to the wearer to make a body position correction to bring the position into alignment with predetermined body position reference data.

A treadmill may include a deck, a first pulley incorporated into the deck, a second pulley incorporated into the deck, a tread belt surrounding the first pulley and the second pulley, a motor in mechanical communication with at least one of the first pulley and the second pulley to move the tread belt in a first direction, and a runaway mitigation mechanism in at least indirect mechanical communication with the motor. The runaway mitigation mechanism at least mitigates a motor runaway condition.

One or more apparatuses are provided. In an example, an exercise machine is provided. The exercise machine may include one or more driving elements connected to one or more motors controlled by a computer. The one or more motors may be configured to provide an electromechanical resistance via the one or more driving elements. The electromechanical resistance may be controlled by smart algorithms running on the computer such that variable resistance is provided at different parts of movement. The algorithms may use readings from one or more sensors. The exercise machine may include a controller configured to control the motor based upon one or more inputs. The exercise machine may include an exercise bar. The exercise machine may include a screen. The exercise machine may include safety actuators. The exercise machine may be fixed on its place or may be portable. The exercise machine may include electromechanical safety stand(s).

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

A treadmill includes a frame, a front shaft assembly coupled to the frame, a rear shaft assembly coupled to the frame and spaced apart from the front shaft assembly, a running belt disposed about the front and rear shaft assemblies, and a motor coupled to the running belt. In a first operating mode of the motor, the force of rotation of the running belt is provided by a user of the treadmill. In a second operating mode of the motor, the force of rotation of the running belt is provided by the motor.

Disclosed is a technical training garment configured for use with modular, interchangeable electronics and resistance modules. The garment provides resistance to movement throughout an angular range of motion and tracks biomechanical parameters such as stride length, stride rate, angular velocity and incremental power expended by the wearer. The garment may be low profile, and worn by a wearer as a primary garment or beneath or over conventional clothing. Alternatively, the device may be worn as a supplemental training tool during conventional training protocols.
