摘要：<p>A system for electromagnetically harvesting waste kinetic energy. A wound electrical coil having a hollow bobbin abuts an opening in ring magnet. An actuator plunger extends through the opening. Fixed magnets are located at the opposite end of the bobbin. Floating magnets are disposed within the bobbin, arranged with their magnetic field opposing that of the fixed magnets but not that of the ring magnet. Axial force on the actuator plunger moves the floating magnets toward the fixed magnets. When the actuator is released, the floating magnets are repelled by the fixed magnets and attracted by the ring magnet, causing the floating magnets to pass rapidly through the coil, thereby generating an electric current in the coil. In one application, the harvester is actuated by a keeper in a door latch release mechanism. In a second application the harvester is actuated by a latch bolt of a lock set.</p>
