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 electric unlocking device for a push bar latch, comprising: a base frame having an external sliding slot; a linear motor having a stepping stud, the stepping stud is equipped with a stud return spring, and the stepping stud has a binding rod; an unlocking unit having a pair of side plate and an end plate, the side plate has a pair of internal sliding slot, and the end plate has a non-circular hole; a binding unit having a limit oval head rivet and a non-circular barrel, the non-circular barrel sets through the non-circular hole and makes the limit oval head rivet arranged inside the unlocking unit, and makes the non-circular barrel combine with the binding rod, sleeves a buffer spring on the non-circular barrel; and an unlocking connecting rod, the outer end is combined with the push bar returning unit, and the inner end is provided with an unlocking pin.

A surface mounted electric strike for selectively retaining a door latch of a door is provided. The electric strike comprises a housing mounted to a surface of the door frame, wherein the housing defines a cavity configured for receiving the door latch. A keeper is mounted within the housing and movable between a latched position and an unlatched position. The keeper includes a keeper body portion and an extended lobe portion having a terminal end. An actuating assembly is configured for moving between a first mode and a second mode, wherein when the actuating assembly is in the first mode the keeper is prevented from moving toward the unlatched position, and wherein when the actuating assembly is in the second mode the keeper is permitted to move toward the unlatched position.

The electric strike can have a housing having an internal face receivable against a receiving face of a door frame, an external strike face, a socket recessed into the strike face along a socket axis normal to the receiving face of the door frame, for receiving a male locking member retractably mounted to a door, the male locking member also being moveable transversally to the socket axis, along a horizontal escape path, by opening the door, the electric strike further having a keeper pivotally mounted around a pivot axis between a closed configuration and an open configuration, the pivot axis parallel to the socket axis and offset from the escape path on a first side of the socket, inside the housing, the keeper having a gate member forming a restraining wall of the socket blocking the escape path when in the closed configuration, and a distal end.

A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.

A remotely controlled cabinet assembly includes a cabinet unit that includes a central cabinet and a door that is hingedly coupled to the central cabinet. A plurality of locking units is each coupled to the central cabinet. Each of the locking units releasably engages the door for locking the door on the central cabinet. A control unit is coupled to the cabinet unit and the control unit is electrically coupled to each of the locking units. The control unit actuates each of the locking units to disengage and thusly unlock the door on the central cabinet. A keypad is coupled to the door and each of the locks disengages the door when an alpha-numeric code is entered into the keypad. An electronic device is carried by a user and the electronic device transmits an unlock command to the control unit for remotely unlocking the door on the central cabinet.

A lock includes a latch and electromagnet configured to open the latch in response to a voltage being applied across the electromagnet. The lock includes a normally closed switch configured to open in response to the voltage being applied across the electromagnet. The lock includes a normally open switch configured to close in response to the voltage being applied across the electromagnet. A method of opening a lock includes applying a voltage across an electromagnet in a lock. The electromagnet is configured to open a latch in the lock in response to the voltage being applied across the electromagnet. The method includes causing the electromagnet to open the latch in response to the voltage being applied across the electromagnet. The method includes opening a normally closed switch by applying the voltage across the electromagnet and closing a normally open switch by applying the voltage across the electromagnet.

A lock (1) with an exterior activation sensor (2) includes an interior electromechanical mechanism (3) with a corresponding power supply unit (4) and an exterior activation sensor (2) situated on the external part of the locker, and which is used in community lockers or similar, wherein the exterior activation sensor (2) contains at least two respective internal electrical contacts (5) which, by means of a conductive circuit (6), reach the inside of the lock and connect in parallel to the interior poles of the circuit (4a) of the power supply unit (4).

A cover is configured to selectively engage with a portion of a structure in response to receiving a wireless electrical power signal at a receiver antenna of the cover from a wireless power source located in an outside environment, to separate a first environment on a first side of the cover from a second environment on a second side of the cover opposite the first side. In response to wirelessly receiving the electrical power signal, a fastening subassembly of the cover changes from a secured mode configured to inhibit opening a cover body with respect to the structure, to an unsecured mode configured to facilitate opening the cover body with respect to the structure. This in turn allows the cover to be matingly engaged with a portion of the structure to form a smooth continuous surface, without any exposed fasteners on the exterior side of the cover.

A locking system for a door, including a primary locking mechanism and a secondary locking mechanism, in which the primary locking mechanism includes an electrical actuator that causes a first plate and a second plate to be magnetically attracted to one another when actuated such that rotation of a doorknob effects a corresponding rotation of the spindle, and in which the secondary locking mechanism includes a detent that is formed in a knob collar and an aperture that extends through a rotator collar; and a pin that is translatable through the aperture to be disposed in the detent of the knob collar, when the secondary locking mechanism is in an unlocked condition, such that the knob collar and the rotator collar are rotatably fixed to one another.
