Claim 15:
16. A method comprising:
providing, by a primary power circuit, a first voltage for use during normal operations;
providing, by a supercapacitor circuit comprising a bank of supercapacitors, a second voltage for use during power loss;
determining if the first voltage is a predefined first voltage level for use during normal operations;
upon determining that the first voltage is the first voltage level, providing the first voltage to an output terminal of a power supply circuit comprising the primary power circuit and the supercapacitor circuit, the output terminal being coupled to a latch circuit;
upon determining that the first voltage is not the first voltage level, providing the second voltage to the output terminal, the second voltage being a predefined second voltage level different from the first voltage level;
applying the voltage on the output terminal to an electronic latch coupled with the latch circuit in response to receiving an unlatch command;
charging, by the primary power circuit, a bank of supercapacitors; and
monitoring the voltage on the output terminal to detect a loss of power from the primary power circuit based on the voltage on the output terminal being different than the first voltage level.
