摘要:
A lock device is adapted to unlock a lock by transferring a lock catch from a locking position to a releasing position. The device comprises an electric motor, which is mechanically connected to an axle by means of at least one transmission means, and rotation of said axle actuates the lock catch. The lock device is characterized in that the transmission means comprise a weakening structure adapted to break and disrupt the mechanical connection between the electric motor and the axle if a predetermined threshold force is exceeded.

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.

A method is presented for unlocking a lock by a lock device enabled for short-range wireless data communication in compliance with a communication standard. In one embodiment, the method includes: a) detecting a key device within operative range of the lock device; b) determining a wireless communication address of the key device; c) evaluating the determined key device address by reference to a data storage with a number of wireless communication addresses stored therein; d) generating an evaluation result from said evaluating step c), wherein a match between the determined key device address and any of the wireless communication addresses stored in the data storage is a requisite for a positive evaluation result; and e) unlocking said lock if a positive evaluation result is generated in step d).

An access control method is disclosed in which a lock device provides conditional access to a protected environment by short-range wireless communication with a key device having a key device identifier (KD_ID). In the method, the lock device requests the key device to provide a challenge response to a challenge generated by the lock device based on a challenge code kept by the lock device. The lock device receives the challenge response from the key device. The challenge response is generated by a remote administration server and is based on the key device identifier of the key device. The generated response is sent to the key device and forwarded from the key device to the lock device. The lock device then verifies the received challenge response based on the challenge code and on the key device identifier of the key device.
摘要:
A data processing apparatus, a method and computer program product for comparing a first object associated with said data processing apparatus with a second object associated with a remote data processing apparatus, are provided. The data processing apparatus comprises an input device operable to accept a first and a second set of data associated with said first object. Said first set of data describes said first object, and said second set of data describes a third object. Additionally, the data processing apparatus includes a memory. Said memory is adapted to store said first and said second set of data. The data processing apparatus further comprises a receiver. Said receiver is adapted to obtain a first subset of a third and a fourth set of data, respectively, from said remote data processing apparatus. Said third and said fourth set of data is associated with said second object, and said third set of data describes said second object, and said fourth set of data describes a fourth object. It also includes a transmitter. Said transmitter is adapted to send a first subset of said first and said second set of data, respectively, to said remote data processing apparatus. Finally, the data processing apparatus comprises a processor. The processor is adapted to perform correlation analysis between said first subsets of said first and said fourth set of data, respectively, to obtain a first value of correlation between said first and said second object. The processor is further adapted to perform correlation analysis between said first subsets of said second and said third set of data, respectively, to obtain a second value of correlation between said first and said second object.
