The present invention utilizes operation of a valve actuator to generate electrical power. A portion of the mechanical energy generated by operation of a valve actuator is converted to electrical energy. The mechanical energy may be converted to electrical energy at the same time as the valve actuator is operating or the mechanical energy may be stored for later conversion. A valve actuator may be operated manually, electrically, pneumatically, or hydraulically. Generated electrical energy may also be stored.

A therapeutic and exercise device includes a frame; a hand crank coupled to the frame which is rotatably movable by a user, the hand crank coupled to a vertically oriented rail such that the hand crank is adjustable in a vertical plane fore and aft relative to a support surface for the therapeutic and exercise device; a foot crank coupled to the frame which is rotatably movable by the user, the foot crank coupled to a horizontally oriented rail such that the foot crank is adjustable in a horizontal plane; and a brake coupled to the frame and to at least one of the hand crank or the foot crank, the brake configured to selectively apply a braking force to said at least one of the hand crank or the foot crank to resist rotational movement of the at least one of the hand crank or the foot crank.

The present invention is able to extract significant amounts of energy from a user who is walking or running while remaining discreetly hidden near an area of the body where many people already carry things (e.g. wallet, smartphone, keys). The user benefits by keeping their device(s) charged for a longer period of time without the need for external batteries. In addition, the present invention encourages an active lifestyle, which has been shown to promote good health and reduce the risk of many diseases.

Various embodiments related to a recumbent therapeutic and exercise device are provided herein. The recumbent therapeutic and exercise device includes a frame; a hand crank system coupled to the frame, the hand crank system including a hand crank rotatable by a user, wherein the hand crank is movable in a substantially vertical plane closer to and further from a support surface for the frame; and a foot crank system coupled to the frame, the foot crank system including a foot crank rotatable by the user, wherein the foot crank is movable in a substantially horizontal plane relative to the support surface for the fame.

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.

The present invention relates to a self-power generating apparatus that can generate power by converting an external force that alternately acts in a forward and reverse direction into a unidirectional force, and can generate power by winding a wire around a pulley axially coupled to a drive shaft and applying, by a user, an external force to the wire with his/her hands to rotate the pulley in a forward and reverse direction, thereby enhancing power generation efficiency. To this end, the self-power generating apparatus comprises: a drive shaft alternately rotated by an external force in a forward and reverse direction; a forward power transmission part that transmits only the forward rotating force of the drive shaft to a power generating shaft; a reverse power transmission part that transmits only the reverse rotating force of the drive shaft to the power generating shaft; and a power generator that generates power using a unidirectional rotating force of the power generating shaft.
