发明名称 DOOR LOCK RECORDING DEVICE
摘要 <p>A device electronically tracks the use of a key to open or close a lockset and retain information of the key to allow a user to query the device and receive information with respect to the last recorded status. The device includes an actuating arrangement to allow tracking of the acceleration of the key during a locking or unlocking motion. These tracked signals are evaluated relative to at least two known signals indicative of a locking movement or an unlocking movement. The user is able to query the device at a later point in time and receive timing information of the present status and timing information between changes in status.</p>
