Abstract

The present invention is a dead front actuating assembly, including a first layer having at least one selectively illuminated area, and a second layer having a plurality of sensors used for activating the at least one selectively illuminated area such that the at least one selectively illuminated area becomes illuminated, and the first layer is adjacent to the second layer.

Claims

1. A dead front actuating assembly, comprising:

a first layer that includes a microlens that projects light in a specific area and control the angles that light is emitted eliminating the need for a graphics layer, said first layer having at least one selectively illuminated area;

a second layer connected to said microlens to said first layer, said second layer having a plurality of sensors used for activating said at least one selectively illuminated area such that said at least one selectively illuminated area becomes illuminated; and

a dead front cover connected to said first layer, wherein said dead front cover is opaque with respect to electromagnetic radiation in the visible portion of the spectrum of electromagnetic radiation and transparent with respect to the radio frequency portion of the spectrum of electromagnetic radiation.

2. The dead front actuating assembly of claim 1, further comprising a B-pillar of an automobile, said cover plate forming a portion of said B-pillar of said automobile.

3. The dead front actuating assembly of claim 1, further comprising a third layer, wherein a portion of said third layer allows light from said at least one selectively illuminated area to pass through said third layer, and said first layer is located between said second layer and said third layer.

4. The dead front actuating assembly of claim 3, wherein said at least one selectively illuminated area further comprises an electroluminescence area, and when said at least one selectively illuminated area is illuminated, said layer of graphics provides the location of each of said plurality of sensors.

5. The dead front actuating assembly of claim 1, further comprising:

a controller operably associated with said first layer such that at least one of said plurality of sensors is used for detecting the presence of an object in proximity to said first layer and said second layer, and at least one of said plurality of sensors is used for providing a signal to said controller, and said controller will activate said at least one selectively illuminated area when said object is detected in proximity to said first layer and said second layer.

6. The dead front actuating assembly of claim 5, further comprising a function performed by said controller when said controller receives said signal from said at least one sensor used for providing a signal to said controller.

7. The dead front actuating assembly of claim 6, wherein said at least one sensor used for providing a signal to said controller provides a plurality of signals, and said plurality of signals command said controller to perform said function.

8. The dead front actuating assembly of claim 6, said function further comprising unlocking and locking a door of an automobile.

9. The dead front actuating assembly of claim 1 wherein said microlens further comprises at least one light source, and said at least one selectively illuminated area is formed as a portion of said microlens.

10. The dead front actuating assembly of claim 1, said second layer further comprising a printed circuit board, wherein said plurality of sensors are mounted on said printed circuit board.

11. A dead front actuating assembly for a vehicle, comprising:

a first layer having at least one selectively illuminated area, wherein said first layer includes a mircrolens that projects light in a specific area and controls the angles that light is emitted eliminating the need for a graphics layer;

a second layer connected to said first layer having a plurality of sensors, operably associated with said first layer;

a dead front cover connected to and concealing said first layer and said second layer, wherein said dead front cover is opaque with respect to electromagnetic radiation in the visible portion of the spectrum of electromagnetic radiation and transparent with respect to the radio frequency portion of the spectrum of electromagnetic radiation; and

a controller for receiving a plurality of signals from said plurality of sensors, and when said controller receives said plurality of signals from said plurality of sensors, said controller will perform a function in said vehicle.

12. The dead front actuating assembly of claim 11, said first layer further comprising an electroluminescence strip, said at least one selectively illuminated area further comprising at least one electroluminescence area.

13. The dead front actuating assembly of claim 11, further comprising said controller will actuate said at least one selectively illuminated area to become illuminated when at least one of said plurality of sensors senses the presence of an object near said second layer, and when said at least one of said plurality of sensors for sensing the presence of an object near said second layer senses an object.

14. The dead front actuating assembly of claim 11, further comprising when said at least one selectively illuminated area is illuminated, said at least one selectively illuminated area projects light through said cover plate, allowing at least a portion of said first layer to be seen.

15. The dead front actuating assembly of claim 11, said vehicle further comprising a B-pillar, wherein said cover plate comprises a portion of said B-pillar.

16. The dead front actuating assembly of claim 11, wherein said controller is used for performing a function in said vehicle when said controller receives said plurality of signals from said plurality of sensors.

17. The dead front actuating assembly of claim 16, said function further comprising unlocking and locking a door of said vehicle.

18. The dead front actuating assembly of claim 11, wherein said microlens further comprising at least one light source, and when said at least one light source is illuminated, said microlens directs light from said light source to produce a desired beam pattern through said cover plate, indicating the position of said plurality of sensors.

19. The dead front actuating assembly of claim 11, said second layer further comprising a printed circuit board, wherein said plurality of sensors are mounted on said printed circuit board.

20. A dead front actuating assembly for performing a function in a vehicle, comprising:

a first layer having at least one selectively illuminated area, wherein said first layer includes a microlens that projects light in a specific area and controls the angles that light is emitted, eliminating the need for a graphics layer;

a sensor printed circuit board having a plurality of sensors adjacent said at least one selectively illuminated area;

a dead front cover for concealing said first layer and said sensor printed circuit board, wherein said dead front cover is opaque with respect to electromagnetic radiation in the visible portion of the spectrum of electromagnetic radiation and transparent with respect to the radio frequency portion of the spectrum of electromagnetic radiation; and

a controller for receiving at least two types of signals from said plurality of sensors, and when said controller receives one of said at least two types of signals from said plurality of sensors, said controller will command a door of a vehicle to lock or unlock, and when said controller receives another of said at least two types of signals from said plurality of sensors, said controller will command said first layer to activate said at least one selectively illuminated area.
