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

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 hinge status and an indication that a person is trying to hang themselves from the door.

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 1 wherein the energy sensor is disposed between the first door skin and the second door skin.

5. 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.

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

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

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

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

10. A door assembly as recited in claim 1 wherein the door component operation status signal also corresponds to a virtual force applied to the door.

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

12. A system comprising:

a door assembly as recited in claim 1;

a central controller in communication with the controller.

13. 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 hinge status and an indication that a person is trying to hang themselves from the door.

14. A method as recited in claim 13 wherein generating the door component operation status signal also corresponds to an improperly adjusted door operator assembly.

15. A method as recited in claim 14 wherein generating the door component operation status signal also corresponds to a door position.

16. A method as recited in claim 13 wherein generating the door component operation status signal also corresponds to a door clearance.

17. A method as recited in claim 16 further comprising communicating the door operation status signal to a central controller.
