A game system comprises of game pieces with 2D Barcodes, Skill Management Module, Server Devices, and Client Device is revealed. A player scans the 2D Barcodes, receives automatically graded tasks or manually graded tasks. Then upload task completion results and receive reward points, reward badges or reward pictures. The first player or the first team of players who earned the pre-required points, or badges, or pictures wins the game.

This invention describes an electric drive mechanism (120) for translating a blocking member (126) to secure or release a lock. The lock is configured as a latch lock (100), a slide bolt padlock (200), a U-shackle padlock (300) or a snap padlock (400). The blocking member (126) is supported by two or more steel balls (130) disposed in helical grooves formed on a helical member (124) to provide a self-centering and low friction drive mechanism (120), which allows an electric motor (122) connected to the helical member to be small and of low power. Unobstructed movement of the blocking member (126) is provided by an alignment or detent mechanism (160, 217, 317) or torsion spring in the snap padlock (400). An electronic control board (140) allows electronic operation of the lock via an application in a smartphone. A PCB (121) located near the electric motor provides tamper-proofing.

This disclosure provides systems and methods for lockout-tagout procedures and systems supporting the same, including, without limitation, locking devices that can store and be locked simultaneously by multiple keyholders. In various embodiments, a single user can add multiple keyholders to a locking device. The user may not be able to remove anyone as a keyholder except himself or herself. Thus, the locking device may remain in a locked state until each of the added keyholders applies their digital key, password, PIN, and/or other personal identifying information to unlock the locking device by removing themselves as a keyholder.

A laminated padlock comprises a laminated padlock body formed by laminating a plurality of lock sheets, a lock core assembly, and a lock beam connected with the top of the laminated padlock body. The lock core assembly comprises a first lock tongue, a second lock tongue, a large frame, a small frame, a lock core shaft and cipher wheels; the large frame is provided with a positioning resilient piece, and the lower end of the large frame is provided with a limiting plate with a limiting chuck; shaft holes; the small frame is provided with a small resilient piece, and a branch plate is arranged below. The laminated padlock achieves dual guarantee, perfectly solves the defect that the ciphers can be changed by a cipher adjusting rod under the condition of not knowing the ciphers when the lock beam is opened and greatly enhances the safety performance of the laminated padlock.

Systems and methods for controlling access to a secured space are disclosed herein. The systems include a locking device fastenable to an access point of the secured space, a server, and a network for communication between the locking device and server. The locking device includes an actuator, a memory, and a processing unit for generating a control signal for the actuator to move the locking device into a locked state or a closed state. The locking device also includes a body having: a rotatable locking cam, a locking pin; at least one of a group comprising a torsion spring and a magnetic core of the locking pin; and a power supply. The locking device also includes a shackle having two arms configured to be inserted into the body.

A theft deterrent device includes a locking portion and a housing portion. The locking portion includes a locking mechanism. The housing portion includes a housing portion wall. The housing portion wall comprises a first material and is configured to house a second material within the housing portion wall. The second material is made of a different material than the first material. The second material is selected such that a cutting tool will be hindered when trying to cut through the housing portion.

Moto-controlled lock apparatus/mechanism that deploys locking pins to retain the shackle when the lock apparatus/mechanism is in the closed position. Generally, when the lock apparatus/mechanism is in the closed position, the locking pins are prevented from moving by a blocking cam. In various embodiments, the blocking cam is actuated by a motor that rotates the blocking cam, thereby forcing the locking pins into and holding the locking pins in compatibly-shaped cutouts in the shackle.
