Abstract

A sensor system for a door is includes a door configured to provide selective access between a first area and a second area; a door controller for controlling whether the door can open or be in a closed and locked position; a motion sensor for detecting motion in an area proximate to the door, the motion sensor configured to be operatively connected to the door controller; an object recognition sensor for recognizing objects in an area proximate to the door and proximate to the area where motion sensor detects motion, the object recognition sensor configured to be operatively connected to the door controller.

First claim

We claim:

1 . A sensor system for a door comprising:
a door configured to provide selective access between a first area and a second area; a door controller for controlling whether the door can open or be in a closed and locked position; a motion sensor for detecting motion in an area proximate to the door, the motion sensor configured to be operatively connected to the door controller; an object recognition sensor for recognizing objects in an area proximate to the door and proximate to the area where motion sensor detects motion, the object recognition sensor configured to be operatively connected to the door controller.

2 . The sensor system of claim 1 , further comprising a sensor header configured to have the motion sensor and the object recognition sensor mounted to the sensor header in a manner to allow the motion and object recognition sensors to monitor the area proximate to the door and the area proximate to the door and proximate to the area where the motion sensor detects motion respectively.

3 . The sensor system of claim 1 , further comprising a second motion sensor for detecting motion in a second area proximate to the door, the second motion sensor configured to be operatively connected to the door controller to cause the first motion sensor to be deactivated or have the first motion sensor signals ignored by the controller if the second motion sensor detects motion.

4 . The sensor system of claim 1 , further comprising a second object recognition sensor for recognizing objects in an area proximate to the door and proximate to the area where motion sensor detects motion, the second object recognition sensor configured to be operatively connected to the door controller.

5 . The sensor system of claim 1 , wherein the door is a revolving door.

6 . The sensor system of claim 1 , wherein the door controller comprises:
a microcontroller configured to have inputs from at least one motion sensor, and at least one object recognition sensor; and and outputs to an alarm system, a door assembly for controlling whether the door is free to open or remain in a locked position, a memory, and a remote computer system, and wherein the controller is configured to control the outputs based on the inputs.

7 . A sensor system for a door comprising:
a door assembly including a door configured to provide selective access between a first area and a second area; a door controller configured to control whether the door can open or be in a closed and locked position; a first and second wall connected to the door assembly, the first and second wall defining a corridor leading to the door assembly; a first motion sensor configured to detect motion in a first area, the motion sensor operatively connected to the door controller; an object recognition sensor system for recognizing objects in a second area, the object recognition sensor system operatively connected to the door controller.

8 . The sensor system of claim 7 , further comprising a sensor header located over the corridor wherein the motion sensor and the object recognition sensor mounted to the sensor header in a manner to allow the motion sensor to monitor the first area and the object recognition sensor system to monitor the second area.

9 . The sensor system of claim 7 , further including a second motion sensor, attached to the sensor header and configured to monitor motion in a third area.

10 . The sensor system of claim 9 , wherein the first, second and third areas are different from each other, but overlap at least a part of another area.

11 . The sensor system of claim 9 , wherein the first, second and third areas are different from each other, and do not overlap a part of another area.

12 . The sensor system of claim 7 , wherein the object recognition sensor system includes at least one object recognition sensor.

13 . The sensor system of claim 12 , wherein the object recognition sensor system includes three object recognition sensors.

14 . The sensor system of claim 7 , further comprising an alarm system operatively connected to the door controller can configured to activate when any of the motion and object recognition sensors detect an object moving toward the door.

15 . The sensor system of claim 7 , wherein the door controller includes:
a microcontroller configured to have inputs from at least one motion sensor, and at least one object recognition sensor; and and outputs to an alarm system, a door assembly for controlling whether the door is free to open or remain in a locked position, a memory, and a remote computer system, and wherein the controller is configured to control the outputs based on the inputs.

16 . The sensor system of claim 15 , wherein at least one of the outputs and inputs include an internet connection.

17 . The sensor system of claim 7 , wherein the door is a revolving door.

18 . A method of limiting access through a door comprising:
sensing a first area for movement toward the door with a motion sensor; initialing a warning if movement is sensed toward the door; sensing movement toward the door in a second area with an object sensor; locking the door if movement toward the door is sensed in the second area with the object sensor.

19 . The method of claim 18 , further comprising at least one of either:
sending a signal to a remote computer when movement toward the door in a second area with an object sensor; and recording the event of sensing movement toward the door in a second area with an object sensor when movement toward the door in a second area with an object sensor is sensed.

20 . The method of claim 18 , further comprising: maintaining the door in a locked state when movement toward the door in a second area with an object sensor until the door is manually reset.
