Abstract: A system for detecting an intrusion in an electronic device. The system includes at least one optical sensor connected to at least one security module of the electronic device. The optical sensor and the security module are configured to detect a variation in light intensity measured by the optical sensor as compared with a reference light intensity associated with at least one pre-determined light source inside the electronic device. The variation in light intensity represents a risk of intrusion into the electronic device.

Abstract: A point-of-sale (POS) terminal includes a main body, a door attached to the main body, an electric lock attached to one of the main body and the door and including a first movable part configured to move between a lock position and an unlock position using electric power, and a manual lock attached to the other one of the main body and the door and including a second movable part that is manually movable between a lock position and an unlock position. When the door is in a closed state and the first and second movable parts are both at the lock position, the first and second movable parts restrict movement of the door. When the door is in the closed state and at least one of the first and second movable parts is at the unlock position, the door is movable.

Abstract: Described is a locking mechanism for a lock box comprising a plurality of buttons connected to either a sliding dawg or a dummy dawg. The sliding and dummy dawgs are supported by a retaining bar in a first position and can slide into a second position when its corresponding button is pressed. Each dawg comprises a hook that is adapted to engage with a lock bar. The sliding dawgs have hooks that are engaged with the lock bar until the corresponding button is pressed, while the dummy dawgs have hooks that are not engaged with the lock bar unless the corresponding button is pressed. The locking mechanism locks if a button corresponding to a dummy dawg has been pressed, and the locking mechanism can then be opened only by use of a key. The locking mechanism opens if the correct buttons are pressed, regardless of the sequence.

Abstract: A lock housing for a security drawer is disclosed. The lock drawer system includes a cabinet drawer having a front wall including a front surface and a rear surface and a combination lock on the drawer with a combination lock dial.

Abstract: A system for securely storing a weapon. The system includes a tray for containing a weapon. The tray has an opening for accessing a weapon. The system also includes a portable safe having an interior space sized and shaped for retaining the tray and the contained weapon. In addition, the system includes a mounting module attachable to a fixed surface. The mounting module includes an interior space for holding the portable safe and an access control system for locking the portable safe within the interior space of the mounting module. The access control system allows access by an authorized user and denies access of the weapon within the portable safe to an unauthorized user. The weapon is contained in the tray, the tray is retained in the portable safe and the portable safe is held in the interior space of the mounting module.
