Energy harvesting lock system
An exemplary method includes transmitting a wireless power signal from an electrical device connected to line power, receiving the wireless power signal at an electronic access control device, and operating the electronic access control device using electrical power harvested from the wireless power signal. In certain forms, the method further includes adjusting an orientation of the antenna by which the wireless power signal is transmitted.
