The modular asset storage system includes a main panel, the main panel including a computer command module and one or more asset containment modules. The asset containment modules are in data communication with the computer command module.

An electronic locking device including a cylinder and a plug located in the cylinder. Within the plug is a solenoid with a pair of shuttles which move in opposite directions. A control processor controls the solenoids activating the shuttles when connected to the correct key. Blocking elements for each shuttle are inserted through the cylinder and into annular channels in the plug. The blocking elements receive and allow linear movement of the shuttles but prevent their rotation within the annular channels. In a locked condition the shuttles are contained only partially within the annular channels thereby preventing rotation of the plug within the cylinder but in an unlocked condition the shuttles are contained within the annular channels thereby allowing rotation of the plug. The plug also includes a weakness defining a point at which it will break upon application of excessive force.

An electromechanical locking device for a closure element includes a stator, with a rotor, a locking element and a blocking element, wherein the rotor is mounted in the stator, wherein the locking element is movable between two positions, wherein a starting position and a release position can be assumed by the blocking element. In the starting position, the blocking element prevents a movement of the locking element into the second position and in the release position the blocking element enables a movement of the locking element into the second position. The locking device includes a spring element, wherein the spring element interacts with the blocking element such that when the blocking element moves from the starting position into the release position, the spring element is at least temporarily tensioned in such a way that the spring element pushes the blocking element back in the direction of the starting position.

An electronic cylinder that can be actuated by an electronic key, wherein said electronic cylinder includes a stator body, a rotor, a motor that can be actuated by the electronic key, a clutch mechanism configured to lock and unlock the rotation of the rotor with respect to the stator body by means of the actuation of the motor, and a system for detecting rotation of the rotor with respect to the stator body, said system being configured to deactivate the motor when the rotor rotates with respect to the stator body. To this end, the clutch mechanism includes two locking balls which are elements that move radially inside the cylinder, to lock and unlock the rotation of the rotor) with respect to the stator body, said rotation of the rotor being carried out by the electronic key.

A barrier device for a locking device is provided with a stator and with a rotor as two components and with a barrier element. The rotor is mounted in the stator. The barrier element is mounted in a first component of the components and can be moved between a first position and a second position. In the first position, the barrier element engages in a second component of the components. In the second position, the barrier element is disengaged from the second component. The second component has a first contact surface for the barrier element, which moves the barrier element from the first position into the second position when the rotor rotates. The second component further has a second contact surface for the barrier element, which leaves the barrier element in the first position when the rotor begins to rotate. A locking device is provided with the barrier device.
