Theft deterrent lock

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.

         6 . The bicycle lock of  claim 2 , the lock portion further comprising an alarm component configured to, in response to receiving the indication of detected movement from the motion sensing component, activate at least one of an audible alarm component or an optical alarm component. 
     
     
         7 . The bicycle lock of  claim 2 , the lock portion further comprising a transmission component configured to, in response to receiving the indication of detected movement from the motion sensing component, transmit an alarm notification to a remote device. 
     
     
         8 . The bicycle lock of  claim 7 , wherein the remote device is at least one of a mobile phone, a remote network, a local network, or a personal computer. 
     
     
         9 . The bicycle lock of  claim 2 , wherein the securing component is one of a length of cable, a length of chain, or a length of bar, wherein the bar is formed into a U shape. 
     
     
         10 . The bicycle lock of  claim 2 , the lock portion further comprising a power supply configured to provide an electrical charge to the motion sensing circuit. 
     
     
         11 . The bicycle lock of  claim 10 , wherein the power supply is a solar panel. 
     
     
         12 . A method, comprising:
 detecting a change in state of an electrical circuit, wherein the electrical circuit is located in a bicycle lock, wherein the change in state of the electrical circuit in generated in response to motion of the bicycle lock and is detected by a charge sensing component located in the bicycle lock; and   generating an alarm based at least in part upon detecting the change in the electrical circuit, wherein the alarm is generated by an alarm component located in the lock.   
     
     
         13 . The method of  claim 12 , wherein the alarm is at least one of an audible alarm or an optical alarm. 
     
     
         14 . The method of  claim 12 , wherein the alarm is an alarm notification and the generating of the alarm further comprising transmitting the alarm notification to a remote device. 
     
     
         15 . The method of  claim 12 , wherein the charge sensing device detects closure of the electrical circuit based upon an electrical charge changing from a first value to a second value, wherein the first value of the electrical charge indicates the electrical circuit is open, and the second value of the electrical charge indicates the electrical circuit is closed. 
     
     
         16 . The method of  claim 12 , wherein the electrical circuit comprises a leaf spring and a ring contact, motion of the bicycle lock causes motion of a first end of the leaf spring causing the leaf spring to contact the ring contact to close the electrical circuit, closure of the electrical circuit is detected by the charge sensing component. 
     
     
         17 . The method of  claim 12 , wherein the bicycle lock comprises a lock and a securing component, wherein the securing component is one of a length of cable, a length of chain, or a length of bar. 
     
     
         18 . The method of  claim 17 , wherein the electrical circuit is located in the lock of the bicycle lock.
