There is provided a lock control device attachable to a locking mechanism, the lock control device including circuitry configured to receive key information and a process request from a first communication device, the key information including authorization information of the first communication device related to a plurality of types of functions of the lock control device, and determine whether the process request is permitted based on the key information, wherein the key information further includes identification information of the first communication device.

The invention relates to a cascade activation method and mechatronic system for simultaneous generation and consumption. The system includes a non-return diode connected to an electric generator; a first voltage regulator connected to a microcontroller; a voltage converter; and an actuator, which has an activation voltage greater than the first activation voltage of the first voltage regulator. The actuator is configured to simultaneously consume a portion of the electrical energy generated by the electric generator. The method includes the steps of listing the elements of the mechatronic system that require power; calculating the activation sequence of the elements based on the minimum activation voltage and the activation time interval; selecting the electric generator based on the energy/power that needs to be provided to the mechatronic system; and programming the microcontroller with the activation sequence.

A device for unlatching and opening a door of a building to allow exit in the event of a hazardous condition comprises an actuator housed in a supporting frame connected to a strike plate and having a face part that pushes against a latch bolt on the door to disengage the latch bolt from the strike plate. The actuator can be rotated, about a hinge axis, outward from the supporting frame for adjustment of its stroke. A spring or gravity-operated device is provided to urge the door toward its open condition when the latch is released.

A motor-driven wind pressure resistant electric lock strike includes a lock body, the lock body being provided therein with a lock tongue, a lock block assembly, a PCB board, and a drive assembly electrically connected to the PCB board. Hall switches are integrated on both sides of the PCB board. This device replaces the traditional electromagnet drive with a speed reduction motor drive. Motor torque is more powerful than the traditional electromagnet drive. When a door opening signal is given, linking gears drive the lock block to move after the motor rotates. When the lock block is far away from one end of the lock tongue, at this time the lock tongue is in an unlocked state without obstruction. At this time, a lock tongue of a door-pushing mechanical lock pushes the lock tongue to rotate at an angle and retract into a bottom case, thereby realizing unlocking.

An electronic combination lock has a touch panel for combination code entry. If the combination code matches a preset code, a solenoid in energized to unlock the lock, allowing a user to pull up the shackle to open the lock. The user can be a master user, a regular user or a temporary user with each type of users having different level of access. For example, the master user can have unlimited number of times to use the master combination code, while a temporary user has only a limited number of times to use its temporary code as designated by the master user. In one embodiment, the lock can be opened with a key. In another embodiment, the user can enter the combination code from a detached electronic device.

Upon detecting that an operation knob is operated from a lock position to an unlock position within a set time Tset_a and is operated to the lock position based on an input from a potential sensor 15, a control portion 13 of an electronic lock device switches from self-lock control to self-lock temporary stopping control.

An electronically linked cabinet lock includes an electronic device and a locking module. The electronic device includes a sensing element installed onto a surface of the cabinet, and a main body, located in an interior of the cabinet, connected to the sensing element via a signal, and having a movable telescopic rod. The locking module is installed within a telescopic range of the movable telescopic rod and includes a fixed seat, a first slider and a second slider, and the first slider and the second slider are movably installed in the fixed seat, and an end of the movable telescopic rod is connected to the first slider to synchronously link the second slider to move vertically. By triggering the sensing element to generate a drive signal, all slide rails used by the drawers are locked/unlocked synchronously, so as to broaden the scope of applicability and enhance the practicality.

A electronic lock system and method including an electronic lock, a mobile device and/or a wireless device. The electronic lock is capable of sending a message to the mobile device via wireless communication and/or to the wireless device based on a triggering event. The mobile device and/or the wireless device may in turn perform an action based on the received message. In one embodiment, the electronic lock, the mobile device the wireless device communicate with one another wirelessly via Bluetooth communication.

Provided is an auto-open door-lock device including a locking set and a control set. The control set includes a first motor that operates a locking lever and is connected with the locking set, a first micro switch that determines a rotation status of the first motor, a second motor that operates a latch and is connected with the locking set, and a second micro switch that determines a rotation status of the second motor. The locking set includes a locker that fastens a hook and receives a rotational force in a first direction based on a first center, the latch that receives a rotational force in a second direction based on a second center attached to one side, and the locking lever that moves a locking flange that implements a locked state by fastening the locker and including a lever hole track.

The method includes: switching (1202), in a magnetically-operated actuator, between a first mechanical state and a second mechanical state using either a first internal magnetization configuration or a second internal magnetization configuration; after the switching (1202), measuring (1204), by a magnetic sensor, a prevailing magnetic field caused by the magnetically-operated actuator, testing (1206) the prevailing magnetic field against a predetermined condition, and based on the testing (1206), detecting (1208) whether the switching between the first mechanical state and the second mechanical state was completed or not completed.
