Abstract
Official abstract text for this publication.
A method of operating an access control system connectable to a power supply, including the steps of comparing the supplied power voltage to a threshold power supply voltage, determining a power-good condition when the supplied power voltage exceeds the threshold power supply voltage, determining a power-fail condition when the supplied power voltage does not exceed the threshold power supply voltage, and in response to the power-good condition: charging a capacitor to a capacitor charge not less than a threshold charge, and thereafter powering an electromechanical actuator, transitioning the access control system to a first state selected from locked and unlocked states wherein the capacitor charge is not less than the threshold charge upon completion of the transitioning, and in response to the power-fail condition: powering with the capacitor the electromechanical actuator and transitioning the access control system to the another of the locked and unlocked states.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of operating an access control system selectively connectable to a power supply configured to supply power to the access control system when connected thereto, the access control system including a capacitor and an electromechanical actuator operable to transition the access control system between a locked state and an unlocked state, the method comprising the acts of: sensing a voltage of the supplied power; comparing the supplied power voltage t…
