The present embodiments provide a method for unlocking a function of a device using a timepiece including a display device including display elements and a control device driving the display elements in a predefined animation sequence. The method including that the timepiece is placed in front of a detection device, the control device is actuated to drive the display elements in the predefined animation sequence, the predefined animation sequence is detected by the detection device, the detected animation sequence is compared to a reference animation sequence, and if the detected animation sequence is identical to the reference animation sequence, then the function is unlocked.

A device for controlling access to a firearm having a barrel with various physical features proximal thereto, including a muzzle device. The device includes a lock housing with a cavity to receive the barrel. The device also includes a lock mechanism shaft coupled to a lock mechanism that is configured for rotational movement upon actuation of the lock mechanism. The lock mechanism shaft is coupled to a cam that moves axially upon rotation of the lock mechanism shaft. A bidirectional rotatable shaft is coupled to the cam and is insertable into the barrel of the firearm. Embodiments described include variants on the use of a plurality of tabs such as arm, tab, and/or housing configurations to receive and grasp the muzzle device, firearm fixed front sights, bead front sights and/or accessories such as, for example, Picatinny rails, vertical or near vertical serrations, cuts and/or grooves located on the distal lateral and ventral regions of the frame and/or slide.
