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.

A sporting apparatus comprises a structure body, an endless belt, an electricity generating unit, a position sensing unit and a modulation unit for continuously outputting electricity as the sporting apparatus is continuously operated. The electricity generating unit transforms kinetic energy, which is transmitted from the endless belt, into electric power. The position sensing unit senses a position of a user on the endless belt so as to generate a sensing signal. The modulation unit includes a DC/AC inverter, a current sensing element, an inductor and a semiconductor switch with a controller. The current sensing element senses an armature current outputted from the electricity generating unit and outputs a signal to the controller. The controller controls the duty ratio of the semiconductor switch to control the armature current, so that the armature current is adjusted according to the sensing signal for controlling the rotation speed of the endless belt.

A manually operated treadmill includes a running belt defining a non-planar running surface, and an electrical power generator coupled to the running belt and adapted to convert rotational motion of the running belt into electrical power. A rotational speed of the running belt is controllable by a user's relative position longitudinally forward or rearward on the non-planar running surface.

A method for controlling an electric actuator in an exercise device, comprising: supplying a first load set point (F.sub.A, k.sub.A) upon a displacement of the load element in a first direction, supplying a second load set point (F.sub.B, k.sub.B) upon a displacement of the load element in a second direction, and detecting an initial position (M) of the moving part of the electric actuator when the reversal of the movement is detected, computing an end-of-transition position (N) exhibiting a deviation in the second direction relative to the initial position, supplying a transition load set point in the form of a monotonic function of the position of the moving part of the electric actuator or of the load element, said monotonic function varying from the first load set point (F.sub.A, k.sub.A) to the second load set point (F.sub.B, k.sub.B) between the initial position (M) and the end-of-transition position (N).

Improvements to a desk and exercise semi-recumbent bicycle is disclosed, the desk allows a person exercising while utilizing the desk with a computer, as a table or read a book. The desk has a 3-way adjustment relative to the seat for elevation of the desk, angle, sliding forward and backward of the desk or the proximity of the desk relative to the chair and or the pedals. The desk pivots to allow the desk to be easily tilted towards the user when they are studying and tilted away from the user when the user wants to exit the exercise bicycle. The dimension from the seat to the pedals is adjustable to accommodate these different desires. The amount of resistance can be adjusted to increase or decrease the difficulty to accommodate different levels of activity. A recording mechanism can count distance, elapsed time, calories or other information.

A treadmill can 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 drive 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, a runaway load component in electrical communication with the drive motor. The runaway load component draws electrical power generated by the drive motor during a runaway motor condition.

A fitness equipment and an automatic oxygen-generating fitness equipment are disclosed. The fitness equipment comprises a power unit, a sensor unit and an oxygen-generating assembly. The power unit comprises a belt drive turnplate, a belt and a magnetic wheel. Rotation of the belt drive turnplate drives the belt to operate so that the magnetic wheel is driven to rotate. The sensor unit is adapted to detect the belt drive turnplate and generate an activation signal when the belt drive turnplate is rotating. The oxygen-generating assembly comprises a control unit, a motor and an oxygen generator. The control unit is configured to receive the activation signal from the sensor so that the motor is activated to drive the oxygen generator to operate. The control unit may also control the equipment to switch between an oxygen-generating mode and a non-oxygen-generating mode.
