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 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.
Claims30
A digital lock, comprising:
- a semi-hard magnet;
- and
- a hard magnet, wherein:
- the hard magnet is configured to move to open or close the digital lock,
- the semi-hard magnet and the hard magnet are configured adjacent to each other, and
- 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.
3 more elements
A software program product configured to control operation of a digital lock, the digital lock comprising
- a semi-hard magnet;
- and
- a hard magnet, wherein the semi-hard magnet and the hard magnet are configured adjacent to each other;
- the software program product comprising a processing module configured to operate the digital lock, 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 open or close the digital lock, wherein the output module is configured to change the magnetization polarization of the semi-hard magnet to push or pull the hard magnet to open or close the digital lock.
7 more elements
A method for controlling a digital lock, the method comprising;
- changing magnetization polarization of a semi-hard magnet, of the digital lock, to a first state;
- responsive to the change of the magnetization polarization to the first state, pushing or pulling a hard magnet, of the digital lock, to open the digital lock;
- changing the magnetization polarization of the semi-hard magnet to a second state;
- and
- responsive to the change of the magnetization polarization to the second state, pushing or pulling the hard magnet to close the digital lock, wherein the semi-hard magnet and the hard magnet are configured adjacent to each other.
