Abstract: An electric strike lock has a strike body, a latch having a latch bolt and a deadlatch, a keeper having a stop block to abut against the deadlatch, and an adjusting section having an elliptical adjusting hole corresponding to a screw hole on the keeper and an adjusting piece fitting a shape of the elliptical adjusting hole and having an eccentric through hole for an adjusting screw to pass through and to be screwed to the screw hole. The keeper further combined with a solenoid which has a movable rod passing through the keeper and engaging the stop block, and the elliptical adjusting hole has its major axis arranged in the same direction as an axis of the solenoid. By changing the placement of the adjusting piece, the positions of the stop block and the deadlatch can be altered to adjust the strike lock into a fail-safe or a fail-secure strike lock.

Abstract: An electric lock for doors has a housing with an opening, including a first catch and a second catch, an overlap formed by which enables the operation of the present invention. A blocking element connected to a driving device is displaced between an opening position and a closing position whereby the blocking element would stop the first catch from turning when being in the closing position, therefore controlling the turning of the second catch, rendering the opening a locked status and locking up the latch; when the blocking element is in the opening position, the blocking against the first catch would be eliminated, therefore turning the second catch together and rendering the opening an unlocked status, allowing the latch to be unlocked.

Abstract: The invention relates to a security system with power saving feature and device comprises an electric magnet and a corresponding iron plate. The electric magnet is connected to a G-sensor module and the iron plate has a pressing face to contact with the G-sensor module. When the door is opened, the electric magnet does not supply power; when the door is closed, the electric magnet with electromagnetic attraction attracts the iron plate and the pressing face presses the G-sensor module. That is, the electromagnetic lock usually stays in a low-energy attraction state; however, when the G-sensor module is triggered, the electromagnetic lock returns to a normal lock state for achieving power saving effect and control of the external force detection improvement.

The blocking ring of the lock cylinder assembly is sheathed on the lock core body, and a plurality of transverse guide slots is formed on an external wall of the lock core body for accommodating the flat key wafers and the elastic elements, and the flat key wafer can be fixed and reset in the guide slot by the elastic element, and each flat key wafer has at least one combination notch. If a key is inserted into the lock core to push the flat key wafer, each combination notch will be aligned with the lock block and set to a free state for unlocking.

Abstract: A security system with power saving feature includes an electromagnetic lock and a sensing module. The electromagnetic lock is for receiving a limited supply of an electric power supplied by a power supply circuit before a full supply of the electric power is delivered to the electromagnetic lock. The sensing module may cause the full supply of the electric power upon sensing a specific action signal caused by an environment change. Therefore, the electromagnetic lock may operate in a lock state with only the limited supply of the electric power and still operate in the same lock state even after the generation of the triggering signal. Thus, the time during which the electromagnetic lock operates with the full supply of the electric power is minimized, limiting the total power consumption accordingly.

Abstract: The present invention is to provide a human image recognition system capable of determining a next movement of a person approaching a particular region of space, which comprises a determination unit adapted to determine whether there is a moving object in continuous images taken by an image taking unit by analyzing the continuous images. If yes, the determination unit compares the moving object with contours of at least one admissible person stored in a memory so as to determine whether the moving object is a person recognized or is about to enter into or leave from a door of a building by analyzing the person's moving direction and changed positions, and then determine whether the person should be allowed to pass through or not.
