摘要
Some embodiments include electronic circuitry for an electronic lock. The electronic circuitry can include: an antenna configured to receive a wireless signal; a communication processor, coupled to the antenna, configured to decode the wireless signal to ascertain a command to lock or unlock the electronic lock and to authenticate a source of the wireless signal; an energy storage configured to store electrical energy; a motor switch configured to drive a motor clockwise or counterclockwise, powered by the energy storage, depending on a control signal, wherein the motor switch is configured to drive the motor for a short burst of time; and a controller, coupled to the energy storage capacitor and the motor switch, configured to monitor electrical charge left in the energy storage and to output the control signal that corresponds to the command to lock or unlock the electronic lock.
