Abstract

Door sensor hardware is provided that automatically senses the orientation of a door. The door sensor hardware includes electronic circuitry and sensor(s). The sensor(s) determine a current orientation of a door (open, closed, ajar), recent movement, door swing speed, and door acceleration. The door sensor hardware is in communication with at least remote device. The remote device includes a user display to facilitate calibration of the door sensor hardware by a user. The remote device also provides the user with the door orientation as determined by the door sensor hardware.

Claims

1. A door hardware assembly comprising:

door hardware including at least one of a lock assembly, a door hinge, or a door handle;

a door orientation detection circuit including a controller and one or more sensors, the door orientation detection circuit configured to;

generate door position data indicative of a relative orientation of the door with respect to a door jamb; and

calibrate the one or more sensors by;

generating a prompt to close the door;

storing a first position of the door as a closed position in response to receiving an acknowledgement that the door is closed;

generating a prompt to open the door; and

storing a second position of the door as an opened position in response to receiving an acknowledgement that the door is opened;

wherein at least a portion of the door orientation detection circuit is integral with the door hardware.

2. The door hardware assembly of claim 1, wherein the door orientation detection circuit is configured to wirelessly transmit the door position data to a remote device.

3. The door hardware assembly of claim 2, wherein the controller is configured to transmit the door position data in response to detecting a change in door orientation.

4. The door hardware assembly of claim 2, wherein the controller is configured to transmit the door position data in response to detecting a change in door orientation in excess of a predetermined threshold.

5. The door hardware assembly of claim 4, wherein the predetermined threshold comprises a user-selected threshold.

6. The door hardware assembly of claim 2, wherein the remote device comprises a mobile device of a user.

7. The door hardware assembly of claim 1, further comprising a wireless communication interface communicatively connectable to a mobile device.

8. The door hardware assembly of claim 1, wherein the one or more sensors includes at least one sensor selected from the group consisting of:

a magnetometer, an accelerometer, a gyroscope, an inertial measurement unit, and an eCompass.

9. The door hardware assembly of claim 1, wherein the door position data includes at least one of an orientation of the door, door swing speed, or door acceleration.

10. The door hardware assembly of claim 1, wherein the door orientation detection circuit is integral with the door hardware.

11. The door hardware assembly of claim 1, further comprising, based on the first position and the second position, the controller and one or more sensors are configured to detect a current position of the door relative to the door jamb when the door hardware is installed on the door.

12. A door orientation system comprising:

a mobile application executable on a mobile device;

an electronic lock mountable to a door, the electronic lock including;

a bolt movable between locked and unlocked positions via a motor;

a controller configured to actuate the motor in response to an actuation command received from the mobile device;

one or more sensors configured to generate door position data indicative of a relative orientation of the door with respect to a doorjamb;

wherein the electronic lock operates cooperatively with the mobile application to calibrate the one or more sensors by;

generating a prompt to close the door;

storing a first position of the door as a closed position in response to receiving an acknowledgement that the door is closed;

generating a prompt to open the door; and

storing a second position of the door as an opened position in response to receiving an acknowledgement that the door is opened.

13. The door orientation system of claim 12, wherein generating the prompt to close the door further includes displaying the prompt on a user interface of the mobile device.

14. The door orientation system of claim 13, wherein the acknowledgement that the door is closed is received from a user at the user interface.

15. The door orientation system of claim 12, wherein generating the prompt to open the door further includes displaying the prompt on a user interface of the mobile device.

16. The door orientation system of claim 15, wherein the acknowledgement that the door is opened is received from a user at the user interface.

17. The door orientation system of claim 12, further comprising a wireless broadcast token positioned at a predetermined location relative to the one or more sensors.

18. The door orientation system of claim 12, wherein the mobile device is wirelessly connectable to a wireless interface of the electronic lock.

19. The door orientation system of claim 12, wherein the electronic lock operates cooperatively with the mobile application to detect a relative position of the door between the opened position and the closed position.
