The invention relates to a product anti-theft device, which is designed to be attached to products that are to be protected, in particular textile products, the anti-theft device comprising a housing and a locking mechanism, which locking mechanism comprises a needle, the needle being movable between an engaged position, in which it engages with the product that is to be protected, and a release position, in which it allows the product anti-theft device to be released and removed from the product that is to be protected.

An electric lock includes a housing, a manual control member rotatably affixed to the housing, and a clutch mechanism. The clutch mechanism includes a clutch base rotatably affixed to the housing; a retractable plug arranged on the clutch base, wherein the retractable plug is radially movable relative to the clutch base; a driving member abutting against a first end of the retractable plug; and a motor configured to drive the driving member to move relative to the clutch base toward the shaft of the manual control member.

Disclosed are an electronic lock (100) and a light colour control method for the electronic lock (100). The electronic lock (100) comprises a lock body (1), a lock hook (2), at least two shifting beads (3), a lock shifter (4), a motor (5), a motor actuator (6), and an elastic member (7), wherein the shifting beads (3), the lock shifter (4), the motor (5) and the motor actuator (6) are mounted in the lock body (1), the motor actuator (6) is mounted on the motor (5) and interlinked with the lock shifter (4), the lock hook (2) is mounted on the lock body (1) and is able to move with respect to the lock body (1), the shifting beads (3) cooperate with the lock hook (2) such that the electronic lock (100) is transformable between a locked state and an unlocked state, and the elastic member (7) is mounted in the lock body (1) and exerts an acting force on the shifting beads (3) in opposite directions towards the lock hook (2) so that the shifting beads (3) do not exert any acting force on the lock shifter (4) during a progress of unlocking and locking. In the electronic lock (100), the shifting beads (3) do not exert any acting three on the motor (5) during a progress of unlocking and locking, and the motor (5) is in an unloaded state, thereby lowering demand for power supply and for the voltage and power of the motor (5), reducing energy loss and prolonging the service life of the electronic lock.

Locking device having a guard lock for safety doors, comprising a mechanical actuator which can be fastened on a movable door part and a housing which interacts with the actuator and can be fastened to a door counterpart, which housing comprises a receptor to which the actuator can be inserted, and the housing comprises a locking element which is displaceable between an unlocked position, in which the actuator can be released, and a locked position, in which the actuator can be fixed relative to the receptor, wherein the actuator comprises an engagement tongue having an engagement recess for mechanical operative engagement with a head end of a locking element in form of an engagement plunger, the engagement plunger being guided in the housing so as to be longitudinally displaceable a spring-biased manner in the in a plunger longitudinal direction relative to an inner fixed bearing, being shaped as a bushing and carrying radially displaceable and fixable engagement elements which lock the engagement plunger at its inner contour in the locked position during a defined state, for which purpose the engagement plunger comprises an engagement stop at the inner contour which acts in the longitudinal direction.

A latching assembly for releasably securing a first member to a second member, the latch assembly comprising a housing, at least two jaws pivotally mounted to the housing, the jaws pivotable between an open position and a closed position, the assembly comprising a locking member moveable between a locked position to lock the jaws in the closed position and an unlocked position to allow the jaws to revert to the open position.

A cooler access control system locks a cooler when occurrence of an event is detected that requires limiting access to the inside of the cooler. Examples of such events include the loss of power to the cooler for a predetermined period of time, the opening of the cooler door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler door open while stocking the cooler with product.

An electronic door lock system that saves power by putting some electronic devices, such as transceivers, in sleep mode and by executing instructions only in response to ambient trigger scenarios. Instructions sent to an electronic door lock from a remote device could be stored on a server before being downloaded to the electronic door lock system once the transceiver is awakened from sleep mode.

A lock can include a motor assembly, a gear assembly, and an unlocking assembly. The motor assembly can include a motor and a drive shaft. The gear assembly can include a cam, a pinion gear, and a pinion. The pinion gear can include a plurality of teeth disposed along only a portion of a perimeter of the pinion gear. The pinion gear can be configured to engage the pinion. The pinion can be configured to translate laterally to release a biasing member to unlock a door of a container.

An actuating device (12) comprising a stationary structure (20); an actuating element (22) rotatable relative to the stationary structure (20); an electric power source (24, 82); a spindle (26) arranged to be rotated by rotation of the actuating element (22); a locking member (28) movable between a locked position (66) and an unlocked position (86); an electromechanical transfer device (30, 84) arranged in the spindle (26), the transfer device (30, 84) being configured to adopt a locked state (68) and an unlocked state (78); a receiver device (34) fixed with respect to the spindle (26), the receiver device (34) being electrically connected 62 to the transfer device (30, 84); and a transmitter device (32) fixed with respect to the stationary structure (20) and arranged to be electrically powered by the power source (24, 82), the transmitter device (32) being configured to wirelessly transmit power to the receiver device (34).

A three-dimensional printing system for manufacturing a three-dimensional article includes a chassis, a door, and a plurality of latches. The chassis defines an internal process chamber and a vertical opening for accessing the internal process chamber. A peripheral seal surrounds the vertical opening. The plurality of latches are arranged around the peripheral seal. The latches individually include a hook. The vertical door is mounted to the chassis by a linkage. The door includes a plurality of laterally extending pins individually corresponding to the latches. The pins have locations along the door to be individually engaged by the latches when the door is positioned in the closed position. The latches are individually configured to rotate the hooks around a second lateral axis (Y) when the door is positioned in the closed position with the door closing over the opening to secure the door with respect to a first lateral axis (X).
