An illustrative access control system includes a locking assembly operable in locked and unlocked states, and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, and energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between the locked state and the unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device.

A locking device including: a locking pin movable in a linear direction; a tappet movable in the linear direction; and a clamping device connecting the tappet to the locking pin. Wherein the clamping device having an inner spring and an outer spring arranged coaxially relative to each other in the linear direction, and the inner spring is at least partially surrounded by the outer spring in a radial direction orthogonal to the linear direction.

A low-power-consumption intelligent electric lock mechanism includes a lock case, a lock-cylinder housing, a motor, a strike plate, a first reset spring, a central rod, a spiral propulsion structure and a holding block. The lock case is fixed within a door frame, the lock case and a lock inner housing form a chamber for accommodating the lock-cylinder housing, two ends of the central rod are respectively fixed to two side walls of the lock-cylinder housing, one end of the first reset spring is fixed within the strike plate, another end of the first reset spring is held against an inner wall of the lock-cylinder housing, one end of the spiral propulsion structure is mechanically connected with the motor, another end of the spiral propulsion structure is connected with the holding block, a top portion of the holding block is held against a bottom portion of the strike plate.

A surface-mountable electric strike having a keeper arranged to pivot about a first shaft extending in a longitudinal direction; a lock lever for locking the keeper in a door-locking position, the lock lever being arranged to pivot about a second shaft extending in a direction that is transverse to the longitudinal direction and parallel to the backside of the strike; and an actuation mechanism for actuating the lock lever, the actuation mechanism comprising an electromagnet that is situated next to the lock lever in a direction which is substantially perpendicular to the backside of the strike thereby enabling the electromagnet to act directly upon the lock lever providing a simple construction. Moreover, the orientation of the second shaft enables arranging the lock lever, and the electromagnet, above and/or underneath the keeper, thereby reducing the total depth of the strike.

A hands-free door opening system for opening doors without contact includes a foot pull apparatus and a hands-free door hardware apparatus. The foot pull apparatus comprises a pull plate coupled to a door. A pull body coupled to the pull plate and the pull plate define a pull cavity dimensioned to receive a user's foot. The hands-free door hardware apparatus comprises a sensor housing coupled to a wall adjacent the door. A fob sensor is coupled within the sensor housing to recognize the presence of an authorized key fob. A transmitter is coupled within the sensor housing and is in operational communication with the fob sensor. An electronic door handle is coupled within the door and has a receiver in communication with the transmitter to disengage when the authorized key fob is detected.

Lock device (1) which incorporates a closure assembly (2) that can move between an open position and a closed position, a locking device to lock said closure assembly (2) in the closed position, a first actuator (3, 31) and a second actuator (4, 41), both the first actuator (3, 31) and the second actuator (4, 41) having a locked position, in which a locking or retention action is applied, and an unlocked position, both the first and the second actuators having respective control devices which allow orders to be given to change the position of each respective actuator, wherein the first actuator and the second actuator are arranged in such a way that unlocking the locking device requires that both control devices place their respective actuator in the unlocked position.

A safe for the storage of a valuable, such as a firearm. The safe has an imaging system that is used to scan a portion of a human in the near infrared spectrum to image blood vessels and determine if the image matches a stored image and thereafter effect unlocking of the safe. A manual override lock system is provided to manually effect unlocking of the safe.

A locking system for a temperature-controlled container is provided. The container has an interior and a barrier having an open position allowing access to the interior of the container and a closed position blocking access to the interior of the container. The locking system includes a temperature sensor for sensing a temperature within the container; a locking device coupled to the barrier to lock the barrier in the closed position; and a controller in communication with the locking device and the temperature sensor. The controller receives the sensed temperature from the temperature sensor and controls the locking device based on the sensed temperature. The controller is configured to control the locking device to lock the barrier in the closed position when the sensed temperature rises above a predetermined threshold temperature.

A latching structure, a household appliance and a control method for the household appliance are provided. The latching structure has a snapping member, a bracket, a limiting member, and a driving assembly. The snapping member is mounted on a door body and has a hook. The bracket is mounted on a housing and has a limiting portion. The hook can penetrate the bracket. The door body is connected to the housing in an openable and closable manner. The limiting member is rotatably mounted to the bracket and can reciprocate between an unlocked position and a locked position. The driving assembly is configured to engage with or disengage from the limiting member. In the unlocked position, the limiting member avoids the hook, and in the locked position, the limiting member is suitable for fitting the hook to limit a position of the hook.
