Abstract:
A door lock mechanism is disclosed that includes door lock and alarm features. The mechanism includes a controller and a sensor useful to detect motions that are representative of attempted access through a door to which the door lock mechanism is attached. The controller can set an alarm condition if a measured motion, such as a measured acceleration, meet and/or exceeds a threshold. If an appropriate access control credential is provided through a user device then the alarm condition may not be set by the controller. The door lock mechanism can be coupled to a remote station via a communications link if needed, such as a radio frequency link. The remote station can additionally be in communication with the door lock mechanism via a network. The remote station can be used to send and receive messages regarding door lock mechanism status, configuration, etc.

Abstract:
Locks, systems and methods of monitoring a lock, the lock having a hub with a slot rotatable by a handle to open and close a latchbolt. A locking member is moveable into and out of engagement with the hub slot to prevent and permit movement of the hub and latchbolt. A sensor on the lock, adjacent the hub and locking member, monitors a moving lock component. The sensor may sense the position of the locking member in or out of engagement with the hub slot. The sensor may be a reed switch actuated by a magnet on the moving lock component. The lock may further include a magnet mounted on the hub and the sensor may comprise a reed switch capable of being actuated by the magnet on the hub. The lock and system may include an external control unit having an alarm for controlling operation of the lock.
Abstract:
A sensor system for a locking system of a door includes: an acceleration sensor which is designed to detect movements of the door in at least two dimensions and to record a time-resolved acceleration profile; a magnetic field sensor which is designed to detect a magnetic field in the area of the locking system, to detect changes of the magnetic field and to record a time-resolved magnetic field change profile; and a control device which is coupled to the acceleration sensor and to the magnetic field sensor and which is designed to correlate the acceleration profile to the magnetic field change profile, to compare the profile correlation to a predetermined correlation signature, and to output an alarm signal if the profile correlation matches the correlation signature.
Abstract:
The various technologies presented herein relate to detection of a lock is being tampered with, cut, removed, etc. An electrical circuit can be incorporated into a lock portion and a securing portion (e.g., a bar, a cable, etc.) of the lock. The electrical circuit can include a conductive element located along the length of the bar, cable, etc., with an electrical charge applied to the conductive element. Upon damage to the conductive element, e.g., during an attempt to cut or remove the lock, a change in the electrical charge from an initial state can be determined, which can further generate an alarm. The alarm can be a light, speaker, etc. An alarm notification can be transmitted from the lock to a remote device, e.g., a mobile phone, a central monitoring system, etc. A trembler switch can be incorporated into the lock to detect movement of the lock.

Abstract:
An antitheft device attachable to an article, formed by two parts, one part comprises a means for remote interaction with a terminal detecting passage of the device, a hinge to allow movement between a protection position, and a release position, one of the parts having, at the end opposite to the movable hinge, a needle able to move in a direction perpendicular to the mid-plane of the device, the other part comprising a housing for receiving the needle, the housing comprising lock configured to allow the release of the needle with an opener, wherein the first part has three retractable cages enabling the needle to move between a retracted position where the tip of the needle does not project beyond the internal surface of the first part, and a deployed position in which the needle is engaged in the complementary housing when the device is in the closed position.
