Patent attributes
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.
