The method includes: switching (), in a magnetically-operated actuator, between a first mechanical state and a second mechanical state using either a first internal magnetization configuration or a second internal magnetization configuration; after the switching (), measuring (), by a magnetic sensor, a prevailing magnetic field caused by the magnetically-operated actuator, testing () the prevailing magnetic field against a predetermined condition, and based on the testing (), detecting () whether the switching between the first mechanical state and the second mechanical state was completed or not completed.

Electromechanical lock and method

Electromechanical lock and method are disclosed. The lock includes: a movable permanent magnet to move between a first position and a second position; a stationary permanent semi-hard magnet; and an electrically powered magnetization coil positioned adjacent to the stationary permanent semi-hard magnet to switch a polarity of the stationary permanent semi-hard magnet between a first magnetization configuration and a second magnetization configuration. The first magnetization configuration of the stationary permanent semi-hard magnet moves the movable permanent magnet to the first position. The second magnetization configuration of the stationary permanent semi-hard magnet moves the movable permanent magnet to the second position. A magnetic axis of the movable permanent magnet is side by side with a magnetic axis of the stationary permanent semi-hard magnet.

The invention relates to locks. More particularly, aspects of the invention relate to a lock that can be used to lock a door, and which features multiple modes to access the lock in order to open or close the lock. The disclosed lock combines different power sources with different access technologies resulting in a lock that will remain functional for a very long time without maintenance.

Method and means for multi access mode lock system

Electromechanical lock utilizing magnetic field forces. An actuator is moved () from a locked position () to an open position () by electric power. In the locked position (), a permanent magnet arrangement directs () a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates () the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (), the permanent magnet arrangement directs () a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates () the reversed near magnetic field towards the far magnetic break-in field.

The first magnetization configuration of the stationary permanent semi-hard magnet attracts the movable permanent magnet to the first position. The second magnetization configuration of the stationary permanent semi-hard magnet repels the movable permanent magnet to the second position. A magnetic axis of the movable permanent magnet is side by side with a magnetic axis of the stationary permanent semi-hard magnet.

A method and a tag for opening a powerless electromechanical lock are provided. The tag comprises a power source, a near field communication transceiver, an antenna connected to the transceiver, an proximity switch and a controller. The switch is configured to wake up the controller from a low power mode upon a detection of a predetermined signal. The controller is configured after the wake up to activate the near field communication transceiver and control the transceiver to transmit via the antenna wirelessly first operating power to the lock for communication and authentication, perform authentication with the lock and, provided that the authentication is successful, control the transceiver to transmit wirelessly second operating power to the lock for the lock to be set into an openable state.
