Systems and methods for operating a tag. The methods comprise: actuating a telescoping actuator of the tag to transition a pin from an unengaged position in which the pin is retracted into a first portion of the tag's housing to an engaged position in which the pin extends through an insert space and into a second portion of the tag's housing; and mechanically securing the pin in the engaged position using a securement mechanism disposed in the second portion of the tag's housing. The pin is securely coupled to a movable component of the telescoping actuator so as to be integrated into the tag's body, and the first and second portions of the tag's housing are coupled to each other so as to form a unitary piece.

A lock includes a housing and a lock mechanism with a dead-bolt disposed in the housing, wherein the dead-bolt is retractable and protrudable between its two terminal positions. The lock further includes at least one bending element disposed in the housing connected to a mechanical component of the lock mechanism at a connecting location, wherein the longest extension of the bending element is defined along a first axis. When the dead-bolt retracts and protrudes, the connecting location of the mechanical component moves along a second axis. The first axis is angled with regard to the second axis, such that when the dead-bolt is displaced into at least one terminal position, the bending element elastically bends and the bending element maintains the lock mechanism in the terminal position.

A camera housing includes a simplified draw latch for securing a first portion and a second portion of the camera housing together. The draw latch can include a draw hook and a wireform mid-linkage. The draw latch enables a user to easily open and close a camera housing, and to establish an air-tight or water-tight seal between the housing portions for use in various activities, including scuba diving.

An electromechanical lock includes a lever coupled with a locking mechanism configured to receive mechanical power from an user, and to output the mechanical power to mechanically disengage the locking mechanism provided that a support of the fulcrum is in an open position, and a return mechanism for the support of the fulcrum including a reset spring whose other end is configured to, during the reception of the mechanical power from the user, move past the support of the fulcrum with the mechanical power outputted by the lever, and, finally, force the support of the fulcrum with the mechanical energy outputted by the return spring through the lever back to a locked position.
