Abstract: A lock administration system for self-powered locks is provided. The system comprises an ASP (application service provider) server operationally connected to the Internet and configured to store lock system related information, at least one client module configured to control the generating of shared secrets for encrypting and decrypting, and the generating and the encrypting of lock access data packets using a token, transmit the data packets to the ASP server using public networks, receive an encrypted status packet from the ASP server using public networks, control the decrypting of the status packet and send information regarding the decrypt status packet to the ASP server using public networks and at least one lock configured to receive data packets from the ASP server via public networks, decrypt the data packets and send an encrypted status packet to the ASP server using public networks.

Abstract: An electromechanical lock, its key, and its operation method are disclosed. The method includes: during a first and a second insertion phases of a key, conveying mechanical power to an electric generator by a key follower and enabling mechanically operation of an actuator by the key follower; generating electric power from mechanical power by the electric generator; reading data from an external source; matching the data against a predetermined criterion; and during a removal phase of the key, returning the key follower to a starting position and mechanically resetting the actuator to the locked state.

Abstract: Electromechanical lock and its operation method. The lock includes a power transmission mechanism to receive mechanical power produced by a user of the lock; a generator to produce electric power from the mechanical power; an electronic circuit, powered by the electric power, coupleable with a key, to read data from the key, and to issue an open command provided that the data matches a predetermined criterion; an actuator, powered by the electric power, to receive the open command, and to set the lock in a mechanically openable state; and a threshold device to control the power transmission mechanism so that a mechanical tension rises until a predetermined force threshold is exceeded, whereupon the mechanical tension transforms to an action producing the mechanical power received by the power transmission mechanism.

Abstract: An electromechanical lock includes a user interface configured to receive input from a user, the user interface activating operating power for the lock; a memory configured to store access tables, the access tables including information on the keys allowed to open the lock; and an electronic circuitry configured to modify the access tables on the basis of the insertions of an associate master key and an end function key into the lock, the insertion of the associated master key initializing a programming mode and the insertion of an end function key causing the lock to exit the programming mode.

Abstract: An electromechanical lock, and its operation method are disclosed. The method includes: generating electric power from mechanical power by an electric generator; reading data from an external source with the electric power; matching the data against a predetermined criterion with the electric power; powering the electric generator by the electric power; and setting the lock mechanically from a locked state to a mechanically openable state by the electric generator, provided that the data matches the predetermined criterion.

Abstract: An electromechanical lock, its key, and its operation method are disclosed. The method comprises: during a first (818) and a second (820) insertion phases of a key, conveying (802) mechanical power to an electric generator by a key follower and enabling (810) mechanically operation of an actuator by the key follower; generating (804) electric power from mechanical power by the electric generator; reading (806) data from an external source; matching (808) the data against a predetermined criterion; and during a removal phase (826) of the key, returning (815) the key follower to a starting position and mechanically resetting the actuator to the locked state.

Abstract: The invention relates to an electromechanical lock comprising: an electronic circuitry (142) for storing a challenge, providing a wireless interface (126) for a communication device (106) to read the challenge, receiving and storing a response from the communication device (106), and authenticating the response, and for issuing an open command provided that the authentication is successful, the circuitry (142) being configured to receive wirelessly from the communication device (106) operating power for communication with the communication device and to store the response. The lock comprises an actuator (124) to receive the open command and to set the lock in a mechanically openable state, and a user interface (108) configured to receive input from a user, the user interface activating operating power for the authenticating and opening operations.
