  • Publication number: 20200291682
    Abstract: 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.

  • Patent number: 10443269
    Abstract: Electromechanical lock utilizing magnetic field forces. An actuator is moved between a locked position and an unlocked position. In the locked position, a first permanent magnet directs a first magnetic field exerting a pushing force so that rotation of the first axle is blocked, and a second permanent magnet directs a second magnetic field exerting a pulling force so that the first axle is kept uncoupled with the second axle. In the unlocked position, the first permanent magnet directs a reversed first magnetic field exerting a pulling force so that the first axle is released to rotate, and the second permanent magnet directs a reversed second magnetic field exerting a pushing force so that the first axle becomes coupled with the second axle.
