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.
Claims47
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 energy sensor comprises an accelerometer,
- the energy sensor and the memory are disposed on a first door between the first door skin and the second door skin;
- and
- wherein the door component operation status signal corresponds to an operating condition of a door adjacent to the first door.
