Abstract
An alarm system includes a latch assembly having a movable element mounted on one of an entry and a structural element, and a fixed element mounted on the other of the entry and the structural element, wherein the movable element is movable between an engaged position with the fixed element and a disengaged position from the fixed element. A magnet is provided in one of the movable element and the fixed element, and a coil is provided in the other of the moveable element and the fixed element. The magnet and the coil are positioned relative to each other so that an electric current is induced in the coil by the magnet when the movable element is moved between the engaged position and the disengaged position. An energy harvesting circuit connected to the coil converts the induced electric current into a supply voltage that powers the alarm system.
