The invention provides a digital lock (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 digital lock (100, 1001, 1002). The semi hard magnet (310) and the hard magnet (320) are placed adjacent to each other. A change in magnetisation polarisation of the semi hard magnet (310) is configured to push or pull the hard magnet (320) to open or close the digital lock (100, 1001, 1002).

A door lock for a domestic electrical appliance includes a locking member which is electrically switchable between an unlocking position and a locking position, which locking member in the unlocking position allows a closed door of the domestic appliance to be opened and in the locking position is in blocking engagement with a blockable component at least when the door is closed, and an auxiliary member, separate from the blockable component, which is movable in dependence on the closing of the door from a release position into a blocking position. The blocking engagement effects blocking of the closed door against opening. In the release position, the auxiliary member allows the locking member to be transferred from the unlocking position into the locking position; in contrast, in its blocking position, the auxiliary member blocks the locking member against being transferred from the unlocking position into the locking position.

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.

One or more embodiments describe 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 can also be used to realise a valve.

A lock system for an enclosure comprises a locking mechanism selectively disposed in a locked or unlocked position. A first blocking pin prevents the locking mechanism from being moved to the unlocked position when disposed in a first blocking position via a first biasing mechanism. A solenoid mechanism imposes a force on the first blocking pin when in an energized state so that the first blocking pin is placed in an unblocking position. A second magnetizable blocking pin remains in contact with the first blocking pin when the solenoid mechanism is in an unenergized state. A second biasing mechanism biases the second blocking pin toward an unblocking position. During normal operation, the secondary biasing mechanism maintains the second blocking pin in its unblocking position so that the second blocking pin is separated from the first blocking pin when the solenoid mechanism is in the energized state.

A magnetic anti-theft device, includes: a control circuit, in connection with a plurality of magnetic sensors and a control unit; the plurality of magnetic sensors, allowing different magnetic induction strengths to be preset; and an unlock piece, configured with a plurality of magnetic elements corresponding to the magnetic induction strengths of the plurality of magnetic sensors, whereby, when the correct unlock piece is placed on the magnetic sensors, the plurality of magnetic sensors will induct correct magnetic forces, the control unit is driven to release a monitoring state after interpretation of the control circuit; if the induction is incorrect, the control unit is driven to form a warning action after the interpretation of the control circuit so as to achieve an anti-theft effect and increase safety effectively probably because the magnetic force of the magnetic element of the unlock piece is too small or too large.

A locking system is described. The locking system, includes a lock. The lock includes a semi-hard magnet and a hard magnet. The hard magnet is configured to move to open or close the lock, the lock is self-powered using near field communication (NFC), and the lock is digitally controlled using a mobile application.

A door lock for a domestic electrical appliance comprises a movably arranged locking member, which is selectively adjustable into an unlocking position and a locking position and in the unlocking position permits the opening of a closed door of the domestic appliance and in the locking position is in blocking engagement with a blockable component, at least when the door is closed. The blocking engagement causes the closed door to be blocked against opening. The door lock further comprises an electrically controllable actuator for actuating the locking member, and an electrical door detection switch that switches depending on the closing of the door. The doer lock also comprises an electrical auxiliary switch device, which selectively opens or closes an electrical shunt path to the door detection switch depending on the position of the locking member.

Electromechanical lock utilizing magnetic field forces. An actuator is moved (1202) from a locked position (260) to an open position (400) by electric power. In the locked position (260), a permanent magnet arrangement directs (1204) a near magnetic field to block an access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1206) the near magnetic field towards a far magnetic break-in field originating from outside of the electromechanical lock. In the open position (400), the permanent magnet arrangement directs (1208) a reversed near magnetic field to release the access control mechanism to rotate, and simultaneously the permanent magnet arrangement attenuates (1210) the reversed near magnetic field towards the far magnetic break-in field.

An attachment system for a door or window, the attachment system being configured to sense a condition of a door or window, the attachment system including: a securing member configured to be mounted to a frame member of the door or window; and a module, configured to be coupled to a frame member by attachment to the securing member, the module including a sensor to sense the condition of the door or window, and the securing member including a resiliently biased clip configured to retain the module in attachment to the securing member selectively, wherein the securing member is configured space the module from at least part of the frame member such that the sensor is positioned to sense the condition of the door or window.
