Abstract
The invention provides a magnetic actuator 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 magnetic actuator. 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 a digital lock realised with the magnetic actuator. The magnetic actuator of the invention can also be used to realise a valve.
Claims30
A magnetic actuator comprising at least two magnets, characterized in that, one magnet is a semi-hard magnet and other magnet is a hard magnet and the hard magnet is configured to induce mechanical movement by the magnetic actuator.
A software program product configured to control operation of a magnetic actuator comprising at least two magnets, characterized in that,
- one magnet is a semi-hard magnet;
- other magnet is a hard magnet;
- and
- a processing module configured to operate the magnetic actuator, the processing module comprising:
- an input module configured to receive an input from a user interface;
- an authentication module configured to authenticate the input received by the user interface ;
- a database to store identification information of one or more users;
- and
- an output module configured to control a power source to power a magnetization coil to change magnetization polarization of the semi hard magnet in response to successful identification of a user, and configured to control the hard magnet to induce mechanical movement therein.
