Abstract: 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.

Abstract: A system and method for determining a selected weight in exercise equipment (which may include an incremental weight sensor disposed on a shaft rotatably fastened with an incremental weight selection dial). The weight stack incremental sensor produces an electrical signal related to the dial position. A spring element or plurality of spring elements are disposed between a reference member and an unused portion of a weight stack results in spring displacement during an exercise motion. A weight stack sensor disposed between the reference member and the unused portion of a weight stack produces an electrical signal related to displacement. The sensor electrical signals can be used by an electronics unit to compute the total weight lifted by a user of exercise equipment.

Abstract: Electricity is generated in response to use of exercise equipment in a reciprocating motion. An energy harvester system is provided in and responsive to movement of a motion control arrangement of an exercise machine for converting kinetic and ambient light energy supplied from an environment of the exercise equipment into electrical power which is delivered to a feedback system associated with the exercise equipment in order to provide information corresponding to the user of the exercise equipment.
