The invention provides a digital lock (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320). The hard magnet (320) is configured to open or close the digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

The invention provides a digital lock including at least two magnets. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to move to close the digital lock in the event of malicious attack, blocking the intruder thereby the magnets acting as a blocking pin, and the mechanical and/or electromagnetic energy of the attack is configured to move the hard magnet to seal the digital lock from the intruder.

Some embodiments include a lock cylinder comprising: a plug assembly having a front portion and a back portion; a housing shell within which the plug assembly is rotatably disposed, wherein the housing shell includes a notch; wherein the back portion of the plug assembly comprises: a locking pin that is movably disposed, and wherein the locking pin is configured to prevent a rotation of the plug assembly when the locking pin is engaged in the notch and prevented from retracting by a multi-stable mechanism; and the multi-stable mechanism having at least two stable configurations corresponding to respectively to a locked state and an unlocked state, wherein the multi-stable mechanism can maintain the stable configurations without consuming energy; wherein, at a first stable configuration, the multi-stable mechanism prevents the locking pin from retracting, and, at a second stable configuration, the multi-stable mechanism enables the locking pin to retract.

The invention provides a magnetic actuator (100, 1001, 1002) including at least two magnets. One magnet is a semi hard magnet (310) and the other magnet is a hard magnet (320).

The cylinder lock according to the invention includes a body and, inside it, an inner cylinder unit provided with an inner cylinder. The cylinder lock also includes a generator for generating electricity from the movement of a key inserted in the cylinder lock. The electricity generated is used to identify the key, and the electricity generated is also used in the electric device if opening the cylinder lock is allowed on the basis of the identification of the key. In connection with the generator are also generator shaft system, a channel axis and transmission parts from the channel axis to the generator.

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.
