Abstract

A door assembly includes a first door skin and a second door skin spaced apart from the first door skin. The assembly also includes an energy sensor generating an energy signature signal and a memory storing a door component operating signature. A controller is coupled to the accelerometer and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison.

Claims (42)

1. A door assembly comprising:

a first door skin;

a second door skin spaced apart from the first door skin;

an energy sensor generating an energy signature signal;

a memory storing a door component operating signature;

a controller coupled to the energy sensor and forms a comparison of the energy signature signal to the door component operating signature and generates a door component operation status signal in response to the comparison,

wherein the door component operation status signal corresponds to both a latch status and a hinge status.

2. A door assembly as recited in claim 1 wherein the energy sensor comprises an accelerometer.

3. A door assembly as recited in claim 1 wherein the energy sensor comprises a multi-axis accelerometer.

4. A door assembly as recited in claim 3 wherein the energy sensor, the memory and the controller are disposed between the first door skin and the second door skin.

5. A door assembly as recited in claim 1 wherein the energy sensor is disposed between the first door skin and the second door skin.

6. A door assembly as recited in claim 1 wherein the energy sensor, the memory and the controller are disposed between the first door skin and the second door skin.

7. A door assembly as recited in claim 1 wherein the energy sensor and the memory are disposed between the first door skin and the second door skin.

8. A door assembly as recited in claim 1 wherein the energy sensor and memory are disposed with the door assembly, and the controller is disposed in another location from the sensor and memory.

9. A door assembly as recited in claim 1 wherein the energy sensor is disposed within a door operator assembly.

10. A door assembly as recited in claim 1 wherein the energy sensor and memory are disposed within a door operator assembly.

11. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to an improperly adjusted operator assembly.

12. A door assembly as recited in claim 11 where the improperly adjusted door operator assembly comprises a high swing speed.

13. A door assembly as recited in claim 11 wherein the improperly adjusted door operator assembly comprises a low swing speed.

14. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a door position.

15. A door assembly as recited in claim 1 wherein the latch status comprises a latch stop not aligned with the door.

16. A door assembly as recited in claim 1 wherein the latch status comprises a latch not securely latching.

17. A door assembly as recited in claim 1 wherein the hinge status comprises a hinge squeaking.

18. A door assembly as recited in claim 1 wherein the hinge status comprises a hinge binding.

19. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a door clearance comprising a door-to-frame clearance.

20. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a door clearance comprising a door-to ground clearance.

21. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to an abuse of the door.

22. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to correct installation of the door.

23. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to compliance with fire codes.

24. A system comprising:

a door assembly as recited in claim 1 ;

a central controller in communication with the controller.

25. A system as recited in claim 24 wherein the central controller generates a graphical user interface.

26. A system as recited in claim 25 wherein the graphical user interface comprises a compliance indicator.

27. A system as recited in claim 25 wherein the graphical user interface comprises a door status indicator.

28. A method comprising:

generating an energy signature signal during door operation;

comparing the energy signature signal to a door component operating signature; and

generating a door component operation status signal in response to comparing,

wherein the door component operation status signal corresponds to both a latch status and a hinge status.

29. A method as recited in claim 28 further comprising generating a sensor signal and filtering the sensor signal to form the energy signature signal.

30. A method as recited in claim 28 wherein comparing comprises comparing the energy signal to a plurality of door component operating signature patterns.
