Electronic lock
First Claim
1. An electronic lockset controller (28) for use with a door-mounted lockset apparatus (10) and operable to function in a low power sleep mode and an active mode, the lockset controller comprises:
- a core processor (340) capable of controlling the operation of electronic devices within the lockset controller according to a set of electronic instructions and including a wakeup signal input, a key card signal input, and a motor signal output, the processor being inactive when the lockset controller is in the sleep mode and active when the lockset controller is in the active mode, a wakeup control module (312) capable of switching the lockset controller from the sleep mode to the active mode upon the happening of a wakeup event and including an external wakeup signal input for receiving an electronic signal indicating the occurrence of a wakeup event that is external to the lockset controller, an internal wakeup signal input for receiving an electronic signal indicating the occurrence of a wakeup event that is internal to the lockset controller, and a wakeup signal output connected to the wakeup signal input of the processor for transmitting an electronic wakeup signal indicating that a wakeup event has occurred, a key card control module (314) capable of acting as an interface between a key card reader (26) and the lockset controller such that electronic data may be transferred between the two devices, the key card control including a key card signal input connected to the key card reader for receiving an electronic signal representative of information stored on a key card, and a key card signal output coupled to the key card signal input of the processor for transmitting an electronic data signal representative of the information stored on the key card, and a motor driver module (326) capable of driving an electrical motor that moves a locking mechanism component of the lockset apparatus between locked and unlocked states, the motor driver comprising a motor signal input connected to the motor signal output of the processor for receiving an electronic power signal representative of the amount of power intended to drive the electrical motor and a motor signal output connected to the electrical motor for transmitting an electrical signal representative of the power signal, wherein the lockset controller switches from sleep mode to active mode when the processor receives a wakeup signal and, once in active mode, if the processor receives an authorized data signal the processor transits a power signal that causes the electrical motor to unlock the locking mechanism.

Abstract
A lockset controller that functions in either a low power sleep mode or an active mode and includes a processor that'"'"'s inactive in the sleep mode and active in the active mode. A wakeup control module switches the controller from the sleep mode to the active mode when a wakeup event occurs. A key card control module acts as an interface between a key card reader and the controller such that electronic data may be transferred between the two devices. A motor driver module drives an electrical motor that moves a locking mechanism component of the lockset apparatus between locked and unlocked states. The controller switches from sleep to active mode when the processor receives a wakeup signal. Once in active mode, if the processor receives an authorized data signal, the processor transmits a power signal that causes the electrical motor to unlock the locking mechanism.
