Abstract

In one embodiment of the present invention, a lock actuating device for a lock mechanism of a lock has a transceiver capable of interaction with a wireless key device, a controller coupled to the transceiver and capable of generating a control signal, and a lock actuator adapted for actuation of the lock mechanism upon receipt of the control signal from the controller. The controller has a sleep mode and an operational mode. The lock actuating device also has a wake-up arrangement including a sensor and associated circuitry. The sensor is positioned to detect the presence of a user in a vicinity of the lock actuating device. The circuitry is adapted to generate a wake-up control signal to the controller upon detection of the user, so as to cause the controller to switch from sleep mode to operational mode.

Claims

1. 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.

2. A lock actuating device according to claim 1, said lock actuating device being mounted to a door having a door handle, wherein said sensor is positioned on or at said door handle and is adapted to generate said detection signal by electrically detecting interaction from said user on said door handle.

3. A lock actuating device according to claim 1, said lock actuating device being mounted to a door, wherein said sensor comprises a door bell button switch.

4. A lock actuating device according to claim 1, wherein said sensor is selected from the group consisting of:

an IR (Infra-Red) sensor, an ultra-sound sensor, an optical sensor, an RF (Radio Frequency) sensor, a pressure sensor, a capacitive sensor, an acoustic sensor or a vibration sensor.

5. A lock actuating device according to claim 1, wherein said sensor is an RF (Radio Frequency) sensor adapted to detect mobile telecommunications traffic to or from a mobile terminal which implements said wireless key device.

6. A lock actuating device according to claim 1, said lock actuating device being mounted to a door, wherein said sensor is a pressure sensor which is located at floor level near said door, so as to detect pressure variations caused by said user when stepping on the floor.

7. A lock actuating device according to claim 1, said lock actuating device being mounted to a door having a door leaf, wherein said sensor is an acoustic sensor or vibration sensor which is adapted to detect door knocks on said door leaf.

8. A lock actuating device according to claim 7, wherein the circuitry of said wake-up arrangement is programmed or designed to apply predetermined wake-up criteria when deciding whether or not to generate said wake-up control signal, and wherein said wake-up criteria include at least one of the detection of more than one door knock within a certain time frame, and a given sequence of short and long door knocks.

9. A lock actuating device according to claim 1, wherein the controller puts itself in sleep mode after a certain period of inactivity.
