Patent ID: 8222993

Claim:
A lock actuating device for a lock mechanism of a lock, the lock actuating device comprising: a transceiver configured to interact with a wireless key device, a controller coupled to the transceiver and configured to generate a control signal, said controller having a sleep mode and an operational mode, a lock actuator configured to actuate the lock mechanism upon receipt of the control signal from the controller, and a wake-up arrangement including a sensor and associated circuitry, the sensor being positioned to detect the presence of a user in a vicinity of the lock actuating device, and the circuitry being adapted to generate a wake-up control signal to the controller upon detection of said user, so as to cause the controller to switch from sleep mode to operational mode, wherein the controller is further configured to: determine and evaluate a wireless communication address of the key device, prior to establishing a wireless communication link between the key device and the lock device, to provide an evaluation result; depending on said evaluation result, establish the wireless communication link and receive verification data from the key device via said transceiver over said wireless communication link, wherein said verification data represents input made by the user by means of the key device; and decide whether to cause unlocking of said lock based on said evaluation of said wireless communication address as well as authentication of said verification data received.
