Abstract
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 hard magnet (320) is configured to open or close the magnetic actuator (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetization polarization of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close a digital lock realised with the magnetic actuator 100, 1001, 1002. The magnetic actuator of the invention can also be used to realise a valve.
Claims26
A software program product executable by operation of one or more computer processors to perform operations, the operations comprising:
- controlling operation of a magnetic actuator comprising at least two magnets, including a semi-hard magnet and a hard magnet;
- receiving an input from a user interface;
- authenticating the input received by the user interface;
- storing identification information of one or more users in a database;
- and
- controlling a power source to power a magnetization coil to change magnetization polarization of the semi hard magnet in response to successful identification of at least one of the one or more users, the semi-hard magnet configured to induce mechanical movement of the hard magnet,
- wherein the magnetic actuator is powered by at least one of:
- (i) mechanical movement of a lever, (ii) mechanical movement of a knob, (iii) electronic digital key insertion, or (iv) NFC.
A method comprising;
- controlling operation of a magnetic actuator comprising at least two magnets, including a semi-hard magnet and a hard magnet,
- wherein the hard magnet induces mechanical movement by the magnetic actuator,
- wherein the magnetic actuator is powered by at least one of:
- (i) mechanical movement of a lever, (ii) mechanical movement of a knob, (iii) electronic digital key insertion, or (iv) NFC,
- wherein the semi-hard magnet and the hard magnet are configured adjacent to each other, and
- wherein a change in magnetization polarization of the semi-hard magnet is configured to push or pull the hard magnet to move the hard magnet between an open position or a close position.
