An iris biometric recognition module includes technology for capturing images of an iris of an eye of a person, whether the person is moving or stationary, and whether the person is located near the iris image capture device or at a distance from the iris image capture device. The iris biometric recognition technology can perform an iris matching procedure for, e.g., authentication or identity verification purposes. The iris biometric recognition module can be incorporated into, for example, a door lock assembly and other access controlled devices, mechanisms, and systems.

The invention belongs to the technical field of locks, and particularly relates to a lock facilitating double-locking from the outside. The lock comprises a cylinder, a cylinder follower, and a bolt component. The lock further comprises a rotating handle, a fixing part fixedly connected with an external supporting surface, a rotating part fixedly connected with the rotating handle and movably connected with the fixing part, a stopper arranged on the fixing part and movably connected with the rotating part, and an adapter movably connected with the rotating part and connected with the cylinder follower. The structure facilitates double-locking from the outside. A restoration structure for restoring the cylinder is not needed. Therefore, the structure is simple, cost is low, the adapter is easy to mount and dismount, a user can adjust the installation mode of the adapter and the cylinder follower, and even non-professionals can install the lock.

An example lock apparatus generally includes a housing, a latch spindle, a drive spindle, an electronic lock mechanism, and an override mechanism. The latch spindle is mounted for rotation relative to the housing, and is operable to actuate a latch mechanism. The drive spindle is mounted for rotation relative to the housing. The electronic lock mechanism is disposed in the housing, and is operable to selectively couple the drive spindle with the latch spindle. The override mechanism is disposed in the drive spindle, and is operable to selectively couple the drive spindle with the latch spindle.

A push and/or pull handle lockset, comprising: latch tongue (4) in first extended position, and operable to second retracted position; biasing means (6) urging the latch tongue (4) in first position; a linking means (12) to link the latch tongue to the actuator (16); sliding shaft (20) extending through lockset roses (27, 36), and operable from first position to second operating position; a biasing means (26) urging the sliding shaft to first position; an engagement means (21) for sliding shaft (20) to engage with actuator (16); lock accommodations (22, 30) for locking means; actuator (16) to translate movement of said sliding shaft to operate latch tongue (4) into second position; locking means (45) interposed between the lockset roses in parallel alignment with sliding shaft (20) including latch arm (46) which is rotatable in and out of lock sockets (22, 30); lockset unit operation is reversed by rotating the lockset unit one hundred and eighty degrees (180°) about it's horizontal lateral axis, changing the direction of actuator (16) or handle (43, 44) operation.

An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.

A stay is provided. A first part (12) including a base (16) for attachment to a wing or to the frame surrounding the wing and an elongate internally threaded tube (24) which is attached to the base (16) in such manner as to be free to pivot with respect to the base. The stay further includes a second part (14) including a rod (58) with threading compatible with that of the tube (24). A locking element (50) with a circumferential groove is attached to and protrudes transversely from the rod (58) and there is a cylindrical element (40) forming part of a base (34) for attachment to the wing or frame. There is first bore in the element (40) for receiving the element (50) and a threaded second bore intersecting the first bore for receiving a cap screw which enters the groove to prevent withdrawal of the element (50) from the first bore. The second bore is closed by a disc (62) with an Allen key hole opening (64) in it through which the capscrew can be turned.

A locking device is provided including a housing, a barrel, an interchangeable core (IC), and a prong driver. The housing extending along a longitudinal axis and including a first slot. The barrel slidably disposed in a hollow interior of the housing, where the barrel is slidable along the longitudinal axis. The barrel including a second slot and a hollow interior to retain the IC. The IC including a key hole and coupled to the prong driver. The prong driver including an engaging element extending from the prong driver perpendicularly to the longitudinal axis into the first slot and the second slot. When a proper key is inserted into the key hole and rotated, the engaging element is rotated within the first and second slots to allow the barrel to slide along the longitudinal axis to lock and unlock the locking device.

An adaptive electric dual-controlled intelligent lock includes a mechanical clutching structure and an intelligent electronic control structure. The mechanical clutching structure includes a lock head, a lock cylinder and a lock tongue, wherein: the lock cylinder includes movable buckles, springs and a bearing. After being inserted into the keyhole of the lock head and then into the locked groove, a key is turned, the movable buckles move in an elastic range of the springs and drive the lock tongue connected with the bearing to swing, thereby realizing a mechanical unlocking process. The intelligent electronic control structure includes a PCB (printed circuit board), a motor and a shifting lever, wherein: a wireless control module is connected with an external mobile intelligent device; after the motor is started, the shifting lever pushes the movable buckles, so that the bearing drives the lock tongue to swing, thereby achieving an intelligent unlocking process.

A to a padlock comprising a lock body and a hoop that is movable between a closed position and an open position and that has a first hoop end and a second hoop end, wherein a first hoop receiver for the first hoop end and a second hoop receiver for the second hoop end are formed in the lock body, and wherein a latch mechanism is provided that is adjustable by a cylinder core that is rotatable about a cylinder axis between a locked position in which the latch mechanism fixes the hoop in the closed position and a release position in which the latch mechanism releases the hoop for a movement into the open position.

A security reinforcement system for a door assembly having a door frame with first and second spaced-apart vertical structural supports and a door hinged thereto has first- and second-channel base plates respectively mountable to the first and second vertical structural support. Pivotally attached to the first and second base plates, respectively, are first and second opposed pluralities of security arms which rotate from a retracted position to an extended position in which security arms of the opposed pluralities extend toward each other across a portion of the door, reinforcing the door when first and second actuator arms operatively coupled to the first and second pluralities, respectively, are rotated from a vertical position to a horizontal position and are releasably coupled together by a sleeve.
