A digital lock including at least two magnets is disclosed. One magnet is a semi-hard magnet and the other magnet is a hard magnet. The hard magnet is configured to open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

A locking system is described. The locking system, includes a lock. The lock includes a semi-hard magnet and a hard magnet. The hard magnet is configured to move to open or close the lock, the lock is self-powered using near field communication (NFC), and the lock is digitally controlled using a mobile application.

A lockout padlock for securing a switch of an industrial plant comprises a lock housing composed of plastic, a hoop, a lock cylinder that has a cylinder housing and a rotatable cylinder core, and a key, with the cylinder core being rotatable between a locked position in which the hoop is locked or lockable to the lock housing and an unlocked position. The lock cylinder has a plurality of tumblers, with each tumbler being movable between a respective release position and a respective blocking position. The plurality of tumblers comprise a plurality of pin tumblers that are spring-loaded in the direction of their respective blocking positions. The plurality of tumblers furthermore comprise a plurality of supplementary tumblers that are not spring-loaded and that are freely movably supported between their respective release positions and their respective blocking positions.

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 open or close the digital lock. The semi hard magnet and the hard magnet are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet is configured to push or pull the hard magnet to open or close the digital lock.

A lock cylinder including a plug, a plurality of key followers, a sensor assembly structured to sense positions of the key followers, and a controller in communication with the sensor assembly. The plug includes a keyway and a plurality of plug tumbler shafts. Each of the key followers is movably seated in a corresponding one of the plug tumbler shafts and includes a sensor interface. The sensor assembly includes a plurality of sensors, each of which includes at least one sensing region. Each of the key followers is associated with one of the sensors via an associative link formed between the sensor interface and the corresponding sensing region. The sensors are structured to generate an output signal indicative of the transverse position of the associated key follower, and the controller is structured to select and perform actions based upon the output signals.

A lock includes a housing, a cylindrical core body and a tumbler unit. The core body is rotatably mounted in the housing, and includes a core axle, and a core tube sleeved on the core axle. The core axle has a helical keyway. The tumbler unit includes a housing pin hole formed in the housing, a tube through hole formed through the core tube, a pin assembly movably mounted in the housing pin hole and the tube through hole, a hole-defining surface defining the tube through hole and having a shoulder surface portion, and a resilient member disposed in the housing and resiliently biasing the pin assembly to abut against the shoulder surface portion and extend into the helical keyway.

A pick-resistant pin tumbler lock having a first stage in which the pins may move but the plug cannot rotate, and a second stage in which the plug may rotate but the pins cannot move. Pin movement inhibitors prevent further movement of the pins once sufficient rearward force is applied to the lock, and a rotation inhibitor prevents rotation of the plug until after the sufficient rearward force is applied.
