Digital lock

A software program product configured to control operation of a digital lock, the digital lock comprising:

• one or more semi-hard magnets;
• one or more hard magnets;
• and
• a blocking pin, wherein a first semi-hard magnet of the one or more semi-hard magnets and a first hard magnet of the one or more hard magnets 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 first semi-hard magnet in response to successful identification of a user, and configured to control the first hard magnet to open or close the digital lock, wherein the output module is configured to change the magnetization polarization of at least one of the one or more semi-hard magnets to push and pull at least one of the one or more hard magnets to, respectively, open the digital lock, close the digital lock, and activate the blocking pin in the digital lock.

A method for controlling a digital lock, the method comprising;

• changing magnetization polarization of a first semi-hard magnet, of the digital lock, to a first state;
• responsive to the change of the magnetization polarization to the first state, one of pushing and pulling a first hard magnet, of the digital lock, to open the digital lock;
• changing the magnetization polarization of the first semi-hard magnet to a second state;
• responsive to the change of the magnetization polarization to the second state, the other of pushing and pulling the first hard magnet to close the digital lock, wherein the first semi-hard magnet and the first hard magnet are configured adjacent to each other;
• changing the magnetization polarization of a second semi-hard magnet to a third state;
• and
• responsive to the change of the magnetization polarization to the third state, pushing or pulling a second hard magnet to activate a blocking pin in the digital lock.
