Abstract
The present application generally relates to battery powered door unlock mechanisms. More specifically, the application teaches an unlock system including a door unlock mechanism, a capacitive circuit having a first time response, a resistive-capacitive circuit having a second time response wherein the second time response is longer than the first time response, a battery for coupling a battery charge to the capacitive circuit and the resistive capacitive circuit in response to a door unlock authentication signal, and a relay for coupling a first charge from the capacitive circuit to the door unlock mechanism in response to the relay being activated by a second charge from the resistive-capacitive circuit after the second time response.
