DOOR LOCK SENSOR AND ALARM
First Claim
1. An apparatus comprising:
- a door lock mechanism structured to operate a lock that permits entry through a door and configured to be installed with a door panel;
a sensor coupled to the door lock mechanism and operable to detect motion of the door, the sensor also operable to output a data signal representative of motion;
a user input device structured to receive an authentication from an authorized user; and
a controller in communication with the sensor and coupled to the lock, the controller operable to analyze the data signal representative of motion and trigger an alarm if the data signal satisfies an alarm condition and the authentication is not received by the controller.

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.

9. An apparatus comprising:
a door lock and alarm mechanism having an inertial motion sensor and a controller operative to receive information from the inertial motion sensor regarding a sensed motion, the door lock and alarm mechanism also including a user input device structured to receive an authentication code that can be used together with the information of the sensed motion to determine an alarm signal, and a communications transmission device coupled with the door lock and alarm mechanism and structured to transmit information between the door lock and alarm mechanism and a server related to the alarm signal. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method of assessing an alarm condition, the method comprising:
-
moving a door lock mechanism affixed to a door as a result of action to gain entry through a door; sensing movement imparted to the door lock mechanism through use of a movement sensor as a result of the moving; comparing the movement with a threshold to determine an action by the door lock mechanism; testing whether a credential offered to gain access through the door has been authenticated through use of a controller coupled with the door lock mechanism; and generating an alarm state signal as a result of the comparing if the credential is not authenticated. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
