## Abstract

A door assembly includes a first door skin, a second door skin spaced apart from the first door skin and a door operator disposed between the first door skin and the second door skin. An arm extends from the door operator. The door operator includes a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position. A current sensor generates a current signal corresponding to the current to the motor. A position sensor in communication with the door arm generates a position signal corresponding to the position of the door relative to the frame. A controller communicates with the sensor and the motor. The controller controls a motor current to the motor in response to the current signal and the position signal.

## Claims

### Claim 1

A door assembly comprising:
a first door skin;
a second door skin spaced apart from the first door skin;
a door operator disposed between the first door skin and the second door skin; and
an arm extending from the door operator,
wherein said door operator comprises:
a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position,
a current sensor generating a current signal corresponding to the current to the motor;
a position sensor in communication with the arm generating a position signal corresponding to the position of the door relative to the door frame; and
a controller communicating with the sensor and the motor, said controller controls a motor current to the motor in response to the current signal and the position signal.

### Claim 2 (depends on 1)

A door assembly as recited in claim 1 wherein the controller increases the motor current to obtain a predetermined movement speed.

### Claim 3 (depends on 1)

A door assembly as recited in claim 1 wherein the controller changes the motor current based on the position signal.

### Claim 4 (depends on 1)

A door assembly as recited in claim 1 wherein the controller changes the motor current based on the position signal at least three times between the open position and the closed position.

### Claim 5 (depends on 1)

A door assembly as recited in claim 1 further comprising a latch operator in communication with the controller, said controller controlling the motor current in response to the latch operator signal.

### Claim 6 (depends on 5)

A door assembly as recited in claim 5 wherein the latch operator is disposed within the door.

### Claim 7 (depends on 1)

A door assembly as recited in claim 1 further comprising an access controller in communication with the controller, said access controller enabling opening of the door.

### Claim 8 (depends on 7)

A door assembly as recited in claim 7 wherein the access controller is disposed at least partially within the door.

### Claim 9 (depends on 1)

A door assembly as recited in claim 1 further comprising a proximity sensor disposed between the first door skin and the second door skin, said proximity sensor generating a proximity signal corresponding to an object approaching the door, said controller controlling the motor current in response to the proximity signal.

### Claim 10 (depends on 1)

A door assembly as recited in claim 1 further comprising an environmental sensor in communication with the controller, said environmental sensor generating an environment signal.

### Claim 11 (depends on 10)

A door assembly as recited in claim 10 wherein the environment sensor comprises at least one of a smoke sensor, a toxic agent sensor, a light sensor and a heat sensor.

### Claim 12 (depends on 1)

A door assembly as recited in claim 1 wherein the door operator comprises a power source disposed between the first door skin and the second door skin.

### Claim 13 (depends on 12)

A door assembly as recited in claim 12 wherein the power source comprises a battery.

### Claim 14 (depends on 12)

A door assembly as recited in claim 12 wherein the power source comprises a rechargeable battery.

### Claim at position 15

15-20. (canceled)

### Claim 21 (depends on 1)

A door assembly as recited in claim 1 wherein a first end of the arm is rotatably coupled to the door assembly and a second end of the arm is slidably coupled within a channel coupled to a door frame.

### Claim 22 (depends on 1)

A communication comprising:
a central controller; and
the door assembly as recited in claim 1,
wherein the door assembly comprises a communication interface for communicating with the central controller.

### Claim 23

(canceled)

### Claim 24

A door assembly comprising:
a door, comprising
a frame, comprising horizontal stiles and vertical stiles;
a first door skin; and
a second door skin spaced apart from the first door skin;
a door operator disposed between the horizontal stiles and the vertical stiles and between the first door skin and the second door skin; and
an arm extending from the door operator,
wherein said door operator comprises:
a motor moving the arm to move the door between a closed position and an open position and between the open position and the closed position,
a current sensor generating a current signal corresponding to a current to the motor;
a position sensor generating a position signal corresponding to a position of the door relative to a door frame; and
a controller communicating with the current sensor, the position sensor and the motor, said controller controlling a motor current to the motor in response to the current signal and the position signal.

### Claim 25 (depends on 24)

The door assembly of claim 24, wherein the door operator further comprises a gear set,
wherein the motor and the gear set are not oriented axially around the same axis.

### Claim 26 (depends on 24)
