Abstract

An electronic door lock including a magnetometer, an accelerometer, and a processor. The processor is configured to determine a status of a door with respect to a door frame using data provided by the accelerometer and magnetometer which collectively generate acceleration data, velocity data and positional data of the door. The processor provides data to a user interface or an alert device indicating one or more of: door open angle, prep-less door position, an acceleration alert, a door position alert, door sag, door frame rub, and triangulation of an intruder.

Claims

1-25. -25. (canceled)

26. A method for determining a status of a door with respect to a passageway, the method comprising:

providing a magnetometer in a door lock;

analyzing magnetometer data of the door generated by the magnetometer;

determining whether one or more operating state thresholds are satisfied based on the magnetometer data, wherein the one or more operating state thresholds indicate that the door is operating in an acceptable operating state when the one or more operating state thresholds are satisfied based on the magnetometer data, and the one or more operating state thresholds indicate that the door is operating in an unacceptable operating state when at least one of the operating state thresholds is unsatisfied based on the magnetometer data; and

providing a status of the door with respect to the passageway signifying whether the door is operating in the unacceptable operating state or the acceptable operating state.

27. The method of claim 26, wherein providing the status of the door comprises providing an alert indicating that an unacceptable condition associated with operation of the door exists when the door is operating in the unacceptable operating state.

28. The method of claim 26, further comprising determining a magnetic field value generated by the magnetometer when the door is in a closed position relative to the passageway;

and

wherein providing the alert signal comprises providing an alert signal in response to a determination that the magnetometer data is different from the magnetic field value determined when the door is in the closed position relative to the passageway.

29. The method of claim 26, further comprising calibrating the magnetometer by determining a first reference magnetic field sensed by the magnetometer when the door is positioned in a closed state.

30. The method of claim 29, wherein calibrating the magnetometer further comprises determining a second reference magnetic field sensed by the magnetometer when the door is positioned in at least one opened state.

31. The method of claim 26, wherein determining the door is operating in an unacceptable operating state comprises detecting one of a propped door state or a forced door condition.

32. The method of claim 26, wherein determining the door is operating in an unacceptable operating state comprises detecting the door has sagged relative to an installation position of the door.

33. The method of claim 26, wherein determining the door is operating in an unacceptable operating state comprises determining the door is positioned at a nonzero angle relative to the passageway for at least a threshold period of time.

34. An electronic door lock for a door that secures a passageway, the lock comprising:

a magnetometer configured to generate magnetometer data based on a sensed magnetic field; and

a processor configured to execute stored program instructions to;

determine whether one or more operating state thresholds are satisfied based on the magnetometer data, wherein the one or more operating state thresholds indicate that the door is operating in an acceptable operating state when the one or more operating state thresholds are satisfied based on the magnetometer data, and the one or more operating state thresholds indicate that the door is operating in an unacceptable operating state when at least one of the operating state thresholds is unsatisfied based on the magnetometer data; and

provide a status of the door with respect to the passageway indicative of whether the door is operating in the unacceptable operating state or the acceptable operating state.

35. The electronic door lock of claim 34, wherein the processor is further configured to provide an alert indicating that an unacceptable condition associated with operation of the door exists when the door is operating in the unacceptable operating state.

36. The electronic door lock of claim 34, wherein the processor is further configured to:

determine a magnetic field value generated by the magnetometer when the door is in a closed position relative to the passageway; and

provide the alert signal in response to a determination that the magnetometer data is different from the magnetic field value determined when the door is in the closed position relative to the passageway.

37. The electronic door lock of claim 34, further comprising an accelerometer configured to generate accelerometer data based on movement associated with the door;

and

wherein the processor is further configured to determine whether a second set of one or more operating state thresholds are satisfied based on the accelerometer data, wherein the second set of one or more operating state thresholds indicate that the door is operating in an acceptable operating state when the second set of one or more operating state thresholds are satisfied based on the accelerometer data, and the second set of one or more operating state thresholds indicate that the door is operating in an unacceptable operating state when at least one of the second set of operating state thresholds is unsatisfied based on the accelerometer data.

38. The electronic door lock of claim 34, further comprising an accelerometer configured to generate accelerometer data based on movement associated with the door;

and

wherein the processor is configured to determine whether the one or more operating state thresholds are satisfied based on the magnetometer data and the accelerometer data, wherein the one or more operating state thresholds indicate that the door is operating in an acceptable operating state when the one or more operating state thresholds are satisfied based on the magnetometer data and the accelerometer data, and the one or more operating state thresholds indicate that the door is operating in an unacceptable operating state when at least one of the operating state thresholds is unsatisfied based on the magnetometer data and the accelerometer data.

39. The electronic door lock of claim 34, wherein the magnetometer comprises at least one of a vector magnetometer or a total field magnetometer.

40. A method for determining a status of a door, the method comprising:

analyzing sensor data related to movement of the door generated by at least one sensor in a door lock;

determining whether a plurality of operating state thresholds are satisfied based on the sensor data, wherein each of the operating state thresholds indicates that operation of the door is operating in an acceptable operating state when the plurality of operating state thresholds are satisfied based on the sensor data, and that operation of the door is operating in an unacceptable operating state when at least one of the plurality of operating state thresholds fails to be satisfied based on the sensor data; and

providing a status of the door with respect to the opening signifying whether the door is operating in the unacceptable operating state or acceptable operating state.

41. The method of claim 40, wherein the at least one sensor comprises a magnetometer and the sensor data comprises magnetometer data.

42. The method of claim 40, wherein the at least one sensor comprises an accelerometer and the sensor data comprises accelerometer data.

43. The method of claim 40, wherein the at least one sensor comprises a magnetometer and an accelerometer, and the sensor data comprises magnetometer data and accelerometer data.

44. The method of claim 40, wherein providing the status of the door comprises providing an alert indicating that an unacceptable condition associated with operation of the door exists when the door is operating in the unacceptable operating state.

45. The method of claim 40, wherein determining the door is operating in an unacceptable operating state comprises detecting at least one of a propped door state, a forced door condition, door sag relative to an installation position of the door, a tailgate condition, or a frame rub condition.
