METHOD OF APPLYING AN ELECTRIC CONDUCTIVE LAYER TO SELECTED PORTIONS OF A MOUNTING FRAME
First Claim
1. A method of applying an electric conductive layer to selected portions of a foam mount, the foam mount in a shape having an enclosed frame surrounding an open area, the frame in cross section having a peripheral surface;
- an inner surface opposite to the peripheral surface, the inner surface defining the open area;
a first side extending from the peripheral surface to first portion of the inner surface, and an opposite second side extending from the peripheral surface to second portion of the inner surface, wherein the inner surface of the foam mount includes open end of a groove and the open end of the groove faces the open area of the foam mount, and the first portion is on one side of the open end of the groove and the second portion is on the other side of the open end of the groove, comprising;
applying a first electric conductive coating over inner surface of the groove;
inserting peripheral edge of a substrate in the groove to completely cover the open area of the foam mount to separate the foam mount into a first section and a second section, wherein the first section comprises the first side and the first portion, and the second half comprises the second side, and the second portion;
applying a second electric conductive coating over the first section, wherein the coating on first portion and the coating on the inner surface of the groove contact one another, andapplying a non-electric conductive coating over the second section.

Abstract
A foam mount of an aircraft window has a groove to receive an electro chromic window. The foam mount is painted by placing a blank in the groove to divide the foam mount into a first section designated to face the exterior of the aircraft and an opposite second section. The groove and the first section are coated with an electric conductive paint, and the second section is covered with a decorative paint. The conductive coating on the foam mount and the conductive coating of the electrodes of the electro chromic window provide an RF shielding to prevent electronic signals from personal electronic equipment from passing through the cabin and door windows of the aircraft. A mask is also provided to coat one section of the foam mount while covering the other section.

9. A method of making an RF shielded window, comprising:
-
providing a foam mount, the foam mount in a shape having an enclosed frame surrounding an open area, the frame in cross section having a peripheral surface;
an inner surface opposite to the peripheral surface, the inner surface defining the open area;
a first side extending from the peripheral surface to a first position of the inner surface, and an opposite second side extending from the peripheral surface to a second portion of the inner surface, wherein the inner surface of the foam mount includes open end of a groove facing the open area of the foam mount and the first portion is on one side of the open end of the groove and the second portion is on the other side of the open end of the groove;providing a transparency having an electric conductive layer over a major surface the transparency, the transparency shaped and sized to fit within the groove of the foam mount and completely cover the open area of the foam mount; providing a substrate having a peripheral shape similar to peripheral shape of the transparency; applying a first electric conductive coating over inner surface of the groove; inserting peripheral edge of the substrate in the groove to completely cover the open area of the foam mount to separate the foam mount into a first section and a second section, wherein the first section comprises the first side and the first portion, and the second half comprises the second side and the second portion; applying a second electric conductive coating over the first section, wherein the second coating on the first section of the foam mount and the first coating on the inner surface of the groove contact one another; applying a non-electric conductive coating over the second section of the foam mount; removing the substrate from the foam mount, and placing the transparency in the groove of foam mount. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A coating mask comprising:
-
a base; a wall mounted on the base and extending upward from the base; a first shim mounted on the base between perimeter of the base and the upright wall; a second shim mounted on the base between the perimeter of the base and the wall, the first and the second shims spaced from on another, and a cover mounted to the first shim to move in a first direction to a closed position, wherein the cover in the closed position is over the base and on the second shim, and to move the cover in an opposite second direction to an open position to expose the wall, wherein the cover has an opening, wherein the opening is sized such that when the cover is in the closed position, the cover overlays the wall. - View Dependent Claims (20)
