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.

An electro-mechanical unlocking device that includes a locking state, a holding state and an unlocking state. The unlocking device includes an arming solenoid and a holding solenoid. In the locking state the arming solenoid moves an arming assembly, which moves a crank and which moves a holding armature from a second position to a first position. In the holding state the holding solenoid is energized and the arming solenoid is de-energizing, which allows the arming armature to moves from the first position to the second position. In the unlocking state the holding solenoid is de-energized, which allows the holding armature and the arming link to move from the first position to the second position. In the locking and holding states a sear blocks the path of the striker and in the unlocking state the sear does not block the path of the striker.

Described are systems for electronic heatsink safety including a system comprising a thermoelectric generator integrated into a heatsink, where the thermoelectric generator includes a first portion exposed to ambient temperature and a second portion contacting the heatsink, and where the thermoelectric generator is configured to produce a current based on a temperature difference between the first portion and the second portion. The system further comprises a first Light Emitting Diode (LED) electrically connected to the thermoelectric generator, where the current is configured to activate the first LED.

An electric strike having two keepers arranged to pivot about respective shafts extending in a longitudinal direction, a lock lever for locking the keepers 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 keepers form side walls of a bolt cavity and are arranged to pivot between a door-locking position and a door-releasing position. Therefore, the bolt may exit the cavity in two directions, e.g., a first direction for a left-handed closure member and a second direction for a right-handed closure member. The strike can thus be mounted in the same orientation for both left-handed and right-handed closure members.

An electric strike having a keeper arranged to pivot about a 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 strike is provided with a bearing element arranged to bear against the lock lever. The bearing element acts as a stop against possible lateral motions of the lock lever. Such motions may be induced by trying to force open the door lock when the lock lever is in the locking position. By providing the bearing element, it is avoided that the forces due to these lateral motions are exerted onto the second shaft that connects the lock lever to the strike.

An inline motorized lock drive is mountable within a lock housing to drive a sliding locking element between a locked and unlocked position. The lock drive includes a reversible motor having a shaft with an auger thereon to drive a lock spring, which drives the locking element. The sliding motion of the locking element is axially aligned with the motor axis to substantially reduce friction. The lock drive is preferably modular and emulates a solenoid lock drive with a control circuit. The control circuit is connected to drive the motor is switchable to default to a locked position or an unlocked position and emulate a “fail safe” or a “fail secure” type solenoid lock drive. The control circuit operates on 12 or 24 volts to replace solenoid locks of either voltage and stores power when power is applied, then uses the stored power to return the lock drive to the selected default state when power is removed.

An example window operator assembly comprises a motor, communication circuitry, and processor circuitry. The communication circuitry being configured to provide a first type of wireless communications and a second type of wireless communication with a first wireless communication system and a second wireless communication system. And, the processor circuitry being configured to identify connection loss between the communication circuitry and the first wireless communication system, and in response, cause the communication circuitry to switch to the second wireless communication system and cause the window operator assembly to perform an action.

An access control device generally includes an electromechanical actuator operable to transition the access control device between a locked state and an unlocked state, an energy storage device operable to store electrical power from a power supply, and control circuitry. The control circuitry is configured to direct a first electrical power from the energy storage device to the electromechanical actuator in response to one or more first criteria. In a fail secure mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the locked state. In a fail safe mode, the first electrical power is configured to cause the electromechanical actuator to transition the access control device to the unlocked state. Certain embodiments further include a user-adjustable switch operable to transition the control circuitry between the fail secure mode and the fail safe mode.

An electro-mechanical unlocking device that includes a locking state, a holding state and an unlocking state. The unlocking device includes an arming solenoid and a holding solenoid. In the locking state the arming solenoid moves an arming assembly, which moves a crank and which moves a holding armature from a second position to a first position. In the holding state the holding solenoid is energized and the arming solenoid is de-energizing, which allows the arming armature to move from the first position to the second position. In the unlocking state the holding solenoid is de-energized, which allows the holding armature and the arming link to move from the first position to the second position. In the locking and holding states a sear blocks the path of the striker and in the unlocking state the sear does not block the path of the striker.
