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.

ASSEMBLY AND CONTROL SYSTEM FOR ACCUMULATORS IN WORKSTATIONS, presenting a system intended for battery control in radio-base stations rack comprising a processing center which controls a switching system, batteries, electromagnetic locks and sensors, in order to prevent non-authorized actions of such batteries inside the racks from occurring.

A system and method for automatically screening anyone arriving to a facility outside of predetermined entry and exit times is provided. The automated screening system denies entry and detains anyone determined to be a threat. An operator may then take the person denied entry into custody or manually override the system to allow the person access to the facility.

The electronic actuator of an electronic padlock according to the invention is arranged to turn the cam piece (5) to release the latch parts (7) from a locking state and to turn the cam piece (5) to hold the latch parts (7) in the locking state. The cam piece (5) comprises a cover part (5A) and a shaft part (5B). The cover part has a central hole (12) for the shaft part. The shaft part (5B) has a shaft pin (15), which is set into the central hole (12). The shaft part also has a connecting part 19, which is arranged to be in contact with the electronic actuator 4. The cam piece further comprises a spring (9,) which is between the shaft pin (15) and the cover part (5A). The spring comprises a first end (9A) and a second end (9B). The first end 9A is arranged to be in contact with the cover part 5A. The second end 9B is arranged to be in contact with the shaft part 5B. The spring is arranged to transmit turning force of the electronic actuator from the shaft pin 15 to the cover part 5A in the direction of said locking state.

A hoistway landing door locking system includes an elevator shaft and an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Also included is a mechanical locking assembly disposed proximate at least one of the access openings, the mechanical locking assembly operable to switch the access opening between a locked condition and an unlocked condition. Further included is an electromagnetic locking assembly operable between an energized condition and an unenergized condition, wherein the energized condition is required to switch the mechanical locking assembly from the locked condition to the unlocked condition.

A domestic appliance (for example, a microwave oven), comprising: a housing; a front door; a retention mechanism (for example including a latch), located within the housing and engageable with the door; wherein the retention mechanism is movable between a first configuration, in which the door is retained in a closed position, and a second configuration, in which the door is non-engaged; an electromechanical actuator (for example a relay), adapted to move the retention mechanism out of said first configuration; and a controller (for example a microprocessor coupled to the relay, the microprocessor being operable in responsive to one or more signals to activate the relay, and thereby release the door from the closed position. Under spring bias, the door thus opens to about 30-45 degrees. The microprocessor-controlled door opening may be operable in three or more modes, including: actuation of a touch switch, remote control, or a microwave end of cooking.

An electronic article surveillance tag including a tag body member and a connecting member having a pin portion releasably engageable with the tag body member, wherein the pin portion extends along a first axis. The tag further includes a locking member having a clutch mechanism including a plunger member formed from a non-ferromagnetic material and an unlocking member connected to the clutch mechanism. The unlocking member is moveable along a second axis perpendicular to the first axis between a locked position and an unlocked position, wherein during movement between the locked position and the unlocked position, the unlocking member moves the clutch mechanism between the first position corresponding to the locked state and the second position corresponding to the unlocked state.

A latch assembly includes a frame and a pawl including a surface for receiving a striker and being movably coupled to the frame between an open and a closed position. A trigger is mounted to the frame and is movable between a locked position and an unlocked position, wherein, in the locked position of the trigger, the trigger is positioned to retain the pawl in the closed position. A striker bar is movably coupled to the trigger and is positioned to be contacted by the striker, wherein the striker bar is configured to move in the course of moving the striker into the pawl. A device for sensing a position of the striker bar, wherein the position of the striker bar is indicative of the position of the striker and the position of the trigger.

An electronic device according to various embodiments of the present invention may comprise: a wireless communication interface; a display; a magnetic stripe transmission (MST) module comprising a coil for inducing generation of a magnetic field; a processor electrically connected to the wireless communication interface, the display, and the MST module; and a memory electrically connected to the processor, wherein the memory stores instructions for controlling the processor, the instructions, when executed, causing the processor to: receive digital card key information for unlocking a door lock apparatus from an external device through the wireless communication interface; convert the digital card information into an MST signal containing the same; activate the MST module in response to an MST module activation request input thereto; and unlock the door lock apparatus by transmitting the converted MST signal through magnetic induction and waking up the door lock apparatus through the transmitted MST signal. Other embodiments are also possible.
