A system and method for mechanically coupling an energy harvester to strength training type exercise equipment is disclosed. An energy harvester with unwanted vibration forces is mechanically isolated from exercise equipment by a system comprising a plurality of mechanically compliant vibration isolators and a ballast mass; a flexible cord, pre-loaded with a near constant force spring is used to transmit motion from the weight stack to the energy harvester; the flexible cord has a force limiting feature to pre-excessive force from being transmitted from the energy harvester to the weight stack during an exercise motion.

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.

A power generation switch apparatus including multiple switch keys, a power generation apparatus that is driven to perform power generation by an operation force applied to the multiple switch keys, multiple switches being supplied with an electric power generated by the power generation apparatus and performing a switching movement by an operation of the multiple switch keys, and a switch signal transmission circuit being driven by the electric power from the power generation apparatus and outputting multiple switch signals that are different from each other in correspondence with the switching movement of the multiple switches.

A device including a frame; an actuator attached to the frame and slidaby movable along a linear axis; a helical member positioned within the frame and rotatably movable with respect to the frame about a helical axis that is parallel to the linear axis; and an electrical generator coupled to the helical member such that rotation of the helical member about the helical axis causes the electrical generator to generate electricity, wherein the actuator and the helical member are configured to cooperate with one another such that motion of the actuator along the linear axis in a first linear direction causes corresponding rotation of the helical member about the helical axis in a first rotational direction and motion of the actuator along the linear axis in a second linear direction causes corresponding rotation of the helical member about the helical axis in a second rotational direction.

Aspects disclosed herein relate to energy harvesting systems for electrified locking device assemblies and related methods. In some embodiments, an energy generating or harvesting system may collect mechanical energy from a locking system into functional electrical power for operating one or more access-control technologies. The energy harvesting systems of the present disclosure may collect mechanical energy from door handle being rotated in both directions. In other words, the energy harvesting system may be structured to convert mechanical energy from both the mechanical input of the user applying pressure to the handle, as well as the return of the handle back to the neutral position. In this way, the energy harvesting system may harvest energy from both directions of handle rotation, increasing the total energy harvested.
