The knob lock of the present invention includes a knob, a first driving unit disposed on the knob, a driving barrel, a second driving unit, a lock unit, and a lock core. When the lock core is in a locked state, the driving barrel is restricted from rotating by the lock core, and the knob rotates alone with respect to the driving barrel. When the lock core is in an unlocked state, the restriction to the rotation of the driving barrel by the lock core is removed, the first driving unit applies a driving force on the second driving unit when the knob rotates, and the driving force rotates the driving barrel to make the lock unit rotate together.

A mobile device, such as a mobile phone, is configured with an application icon on the device display for communications with a combination lock through a wireless signal. The wireless signal includes information indicative of a combination code for operating the combination lock at one of a plurality of access levels, wherein the access levels define the number of access times for unlocking the combination lock. The display is arranged to allow a user to enter a password to unlock the combination lock and, if the user is an administrator, to change the combination codes and the access levels.

Some designs of combination padlock allow users of the padlocks to set the combinations that unlock the padlocks. However, the operations which a user must perform to set the combination of a padlock typically involve manipulating the shank of the padlock by pulling the shank away from the housing of the padlock or pushing part of the shank further into the housing of the padlock, rotating the shank through a certain angle, and holding or fixing the shank in this position while rotating dials of the padlock to change the combination. Such operations are fiddly, and it can be difficult to remember what steps are required to change the combination. Thus there is provided a combination padlock which goes some way towards overcoming or at least ameliorating one or more of the above problems.

A padlock includes a lock body, a locking element movable between a locked position and an unlocked position, a latch, a user manipulable lock interface, an actuator mechanism, and a counter member. When the lock interface is operated to a sequence of N correct code entry conditions, the latch is moved from an initial locked position to an unlocked position. When the lock interface is operated to any one of the plurality of code entry conditions, the actuator mechanism engages the counter member and incrementally advances the counter member toward a stop position. When the lock interface is operated to a sequence of N code entry conditions in which at least one of the sequence of N code entry conditions is an incorrect code entry condition, the counter member is moved from the start position to the stop position before the latch can be advanced to the unlocked position.

An electromagnetic shielding lock box comprises an openable and closable box body. The box body is defined an accommodating groove, made by electromagnetic shielding materials, and has a lock unit and a hooking member. The box body is closed for receiving at least one key while the lock unit is in a locked status and for shielding the transmission of at least one electromagnetic wave signal due to the electromagnetic shielding materials. The lock unit is further limited the hooking member to be locked to the box body. The box body is opened for taking the at least one key out while the lock unit is in an unlocked status to unlock the hooking member from the box body.

An electronic combination lock has a touch panel for combination code entry. If the combination code matches a preset code, a solenoid in energized to unlock the lock, allowing a user to pull up the shackle to open the lock. The user can be a master user, a regular user or a temporary user with each type of users having different level of access. For example, the master user can have unlimited number of times to use the master combination code, while a temporary user has only a limited number of times to use its temporary code as designated by the master user. In one embodiment, the lock can be opened with a key. In another embodiment, the user can enter the combination code from a detached electronic device.

An electromagnetic shielding lock box comprises an openable and closable box body. The box body is defined an accommodating groove, made by electromagnetic shielding materials, and has a lock unit and a hooking member. The box body is closed for receiving at least one key while the lock unit is in a locking status and for shielding the transmission of at least one electromagnetic wave signal due to the electromagnetic shielding materials. The lock unit is further limited the hooking member to be locked to the box body. The box body is opened for taking the at least one key out while the lock unit is in an unlocking status to unlock the hooking member from the box body.

A method of operating a keyless padlock is provided, comprising: establishing communication with the padlock; requesting the padlock serial number from the padlock; receiving the padlock serial number form the padlock; establishing communication with a server having the padlock serial number and the initial password stored in a database; transmitting the padlock serial number to the server with a request to own the padlock; receiving the initial password and a new password from the server after the server has validated the request; transmitting the initial password to the padlock; transmitting the new password to the padlock after the padlock has validated the initial password; receiving confirmation from the padlock that the padlock has stored the new password in the memory of the padlock; and transmitting the confirmation to the server, whereupon the server updates the database to recognize the user as the owner of the padlock.

The disclosed embodiments include a method for tamper-proof protection of containers used for shipment of goods. The system contains a lock with electronic and mechanical components and a controller. A sensor is connected to a lock so that if forms a closed loop. The sensor can be an optical fiber or a distributed arrangement with an optical or an electrical shield. The electronics in the lock provide real time monitoring of the status of the lock. The lock cannot be opened or reproduced due to the signature of the closed loop which is stored in a remote server. Intrusions detected are relayed to an authorized recipient via a variety of communication channels. The data and control of the entire system is protected with several programs targeted to provide cybersecurity.

A combination padlock comprising a body, true gates, a locking ball, a spindle and a plurality of clutches and dials, a shackle which contains a neck, a locking bolt with a neck, the spindle to control the lock opening of the locking bolt and control the alignment of the true gates of the clutches, the plurality of clutches to prevent the lock from being opened when the dials are not in a locked opened combination, the clutches having extended fins with rounded edges, and the plurality of dials to control the rotational movement of the clutches, so that when the extended fins of the clutches are fully aligned with the true gates, a user can pull a knob-side of the spindle to the right so that the neck of the shackle forces the locking-ball to move upward away from the neck of the shackle so as to unlock the padlock.
