A method for door lock calibration, a calibration apparatus, a door lock, and a non-transitory computer storage medium are provided in the disclosure. The method for door lock calibration includes the following. A first magnetic-field-intensity numerology at a position of a door in an ajar state, a second magnetic-field-intensity numerology at a position of the door in an open state, and a third magnetic-field-intensity numerology at a position of the door in a locked state are collected. A mapping relationship between the ajar state of the door and the first magnetic-field-intensity numerology, a mapping relationship between the open state of the door and the second magnetic-field-intensity numerology, and a mapping relationship between the locked state of the door and the third magnetic-field-intensity numerology are transmitted to a database.

A door security apparatus includes a door-locking member and a sensor assembly. The door-locking member removably engages a plate. The door-locking member is a barricade that restricts movement of a door from a closed position to an open position while the door-locking member is engaged with the plate The sensor assembly is configured to detect engagement between the door-locking member and the plate.

A door locking control system includes an armature coupled to a door or a door frame around which the door is opened or closed, a magnetic module provided on the door or the door frame to face the armature and operated to be fixedly brought into contact with or separated from the armature by a magnetic force induced from a change in a magnetic circuit occurring due to the rotation of a first magnetic body provided inside of the magnetic module, a detector configured to detect an open state or a closed state of the door, and a controller electrically connected to the detector and configured to control the operation of the magnetic module according to the open state or the closed state of the door detected by the detector.

A safety switch includes a processor and a display device. The processor is configured to: set an operation mode of the safety switch; an output unit configured to output a mode notification signal for indicating whether the operation mode of the safety switch is in a maintenance mode; receive an input of a display control signal based upon a system operation mode of a switch system including the safety switch and at least one other safety switch. In response to reception of the input of the display control signal based upon a fact that the system operation mode is in a system maintenance mode indicating that at least one of operation modes of the safety switch and the at least one other safety switch is set to the maintenance mode, the display device displays the indication indicating that the system operation mode is in the system maintenance mode.

A lock including a latch provided at one of a door and a cabinet, and a coupler provided at the other one of the door and the cabinet, the coupler including a housing including a latch insertion hole, an engaging lever including an engaging lever body rotatably provided within the housing, a latch insertion groove having a first end of the latch inserted therein by extending from a first end of the engaging part body, and first, second, third, and fourth projections formed by extending a second end of the engaging lever body.

A hinged object, such as a door, window, gate, lid, etc., comprises a first hinge, a second hinge, and an electromechanical locking device mounted on or in the hinged object. A first electrical wire is embedded in the hinged object that couples the electromechanical locking device to the first hinge, the first hinge to couple to a low-voltage power source to supply low-voltage electrical current to the electromechanical locking device via the first electrical wire. A second wire is embedded in the hinged object that couples the electromechanical locking device to the second hinge, the second hinge to couple to the low-voltage power supply to return low-voltage electrical current from the electromechanical locking device to the low-voltage power supply via the second electrical wire.

A gate assembly including a pivoting gate element secured to a doorway and/or passageway and employing a dual actuator latching mechanism having a simple yet unique locking lever and pawl mechanism for remote and manual latch release freeing the gate to swing to an open position, and automatic re-locking of the latching mechanism. The gate assembly includes a frame element for supporting the pivoting gate element and securing the gate to a doorway and/or passageway as well as latching the gate to a closed position at the frame element.

Systems and methods for controlling a plurality of devices in a home automation system may include providing a device proxy for a device connected to the home automation system and setting a new value in a value box of the device proxy, whereby the value box corresponds to at least one of a sensor, control, and metadata of the device. The systems and methods may further include determining one or more rules associated with the device proxy and running the determined one or more rules, whereby the determined one or more rules are indicative of interactive relationships between the device proxy and one or more other device proxies corresponding to one or more other devices connected to the home automation system.

An electronic locking device to secure linear transitioning or sliding doors. The electronic lock may include a bolt driven by a motor between a locked or extended position and an unlocked or retracted position. The bolt may be coupled to a sled, the sled moved by the motor between a forward position, placing the bolt in the locked position, and a rearward position, placing the bolt in the unlocked position. The motor may drive a drive screw to move the sled.

An exemplary electric strike includes a housing and a keeper pivotally mounted in the housing. The strike also includes a plunger having an extended position and a retracted position, a cage including an aperture, and a locking element movably seated in the aperture. The locking element is engaged with the plunger, and the plunger is structured to urge the locking element radially outward as the plunger moves from an extended position toward a retracted position. The strike also includes a sleeve, a transmission engaged with the sleeve, and a motor drivingly coupled to the transmission. The sleeve is structured to selectively prevent radially outward movement of the locking element and retraction of the plunger. The strike also includes at least one of a lost motion connection and an anti-tamper mechanism.
