  • System for harvesting energy from door or door hardware movement
    Patent number: 9748871
    Abstract: An electrical generation system for a door positioned in a doorway includes a hinge arranged to support the door for rotational movement with respect to the doorway between a closed position and an open position, and a cam that is one of coupled to the door for movement with the door, and fixed with respect to the doorway. A piezo-electric generator is the other of coupled to the door for movement with the door, and fixed with respect to the doorway. The piezo-electric generator and the cam cooperate such that rotation of the cam with respect to the piezo-electric generator is operable to produce an electrical current in response to rotation of the door, and wherein the electrical current has a frequency that is greater than the number of revolutions made by the cam with respect to the piezo-electric generator.

  • System for harvesting energy from door or door hardware movement
    Patent number: 9431927
    Abstract: An electrical generation system for a doorway including a door includes a lock mechanism movable between an engaged position and a disengaged position to allow the door to move between a closed position and an open position and a cam coupled to the door. A piezo-electric generator is coupled to the cam. The cam is rotatable with respect to the piezo-electric generator. The piezo-electric generator is operable to produce an electrical current in response to rotation of the cam with respect to the piezo-electric generator, and the electrical current has a frequency that is greater than the number of revolutions made by the cam with respect to the piezo-electric generator.
