An electric lock device for furniture or storage has an RFID transmitter/receiver for communication with portable data carriers. A controller detects a data carrier nearby, reads a set of data from it, and determines if the data carrier is at least an access requesting or function determining type. If access requesting, the controller retrieves identity information from the read set of data, compares the identity information to stored reference information, and controls an electric activator for a securing member. If function determining, the controller retrieves function determining information from the read set of data and performs any of the following: switching to any of a plurality of operational modes having different principles for access control; reading an operational status; or setting an operational parameter. At least one of these actions is variable controlled and based on a variable value in the function determining information.

No matter a latch is extended or retracted at initial state, a method for automatically determining the installation direction of an electronic lock is able to determine the electronic lock is installed on left or right hand door by driving a rotation module to rotate in first or second direction and changing the potential of a signal outputted from a micro switch depending on the rotation module whether touches the micro switch. The method is applicable for more convenient to consumer on installation of the electronic lock.

A smart door lock assembly includes a lock cylinder, a lock cylinder mounting block, a driving motor, and a driving control board. A driving gear is arranged on a movable end of the driving motor. The lock cylinder passes through and is mounted in the lock cylinder mounting block. A driven gear coaxial with the lock cylinder is arranged on the lock cylinder mounting block. The driven gear is driven by the driving gear. The driving control board determines whether an external input unlocking command is right and controls the driving motor to unlock the smart door lock assembly when the external input unlocking command is right. The driving motor has a virtual position in a process of driving the driving gear.

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 method for retrofitting a roll door lock that enables both manual and remote wireless locking and unlocking of a roll door. More specifically, the retrofitted lock comprises an interior plate with a cylinder lock aperture, a motorhead gear coupled to a motor and rotationally secured within the housing, and a controller functionally coupled to the motor, wherein the controller may be commanded to operate the motor to lock the roll door lock by causing a blocking coupler edge to reduce the diameter of a ball-pin aperture, and unlock the roll door lock by withdrawing the blocking coupler edge.

An electronic lock assembly includes an exterior assembly, an interior assembly, and a latch having a deadbolt movable between an extended position and a retracted position, the latch being movable in response to rotation of a torque blade. The electronic lock includes a motor within the interior assembly and operable to rotate the torque blade, and a control circuit operatively connected to the motor and configured to selectively actuate the motor. A mortise insert includes a battery subassembly electrically connectable to the control circuit.

A locking mechanism for a motor is provided. The locking mechanism includes a detent mounted on a shaft coupled to the motor, and a solenoid including an electromagnetic coil, a plunger, and a spring that holds the plunger at an extended state. The plunger engages the detent at the extended state when no voltage is applied, and the spring is configured to exert a predetermined force for the plunger to engage the detent to lock the shaft. The plunger retracts away from the detent to allow rotation of the motor shaft when a voltage is applied to the solenoid.

Systems and methods for providing a wireless lock system include a locking device wherein the locking device comprises a retractable bolt and a wireless communication transceiver. The systems and methods can also include a bolt catch that is configured to couple with the retractable bolt, wherein, when coupled, the bolt and locking device are locked into a static position relative to the bolt catch. A keypad programmable with a plurality of combination buttons and a wireless communication transceiver can be configured to communicate with the bridge wirelessly. The bolt then protrudes from the locking device to couple with the bolt catch and decouples from the bolt catch and recedes into the locking device in response to one or more wireless signals received from a wireless device. A wireless communication bridge device may also be utilized to provide additional wireless communication links to further devices to expand user reach and interoperability.

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.

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.
