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.
Claims20
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.
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.
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.
