Abstract: A lighted insulated glazing assembly including a light source. In a first aspect of the invention, the light source is within the insulated glazing assembly; and power is routed from the light source through the spacer assembly to a battery or wired power source located outside the assembly. In a second aspect of the invention, the light source is outside of the insulated glazing assembly. In both aspects, various light manipulators can be included to manipulate the light in order to create a desired lighting or visual effect.

Abstract: An insulated glass window assembly including a cordless integral shade with level correction, a sliding follower, and an air permeable spacer assembly. Cords are eliminated by confining the window covering movement to one dimension. Level correction is achieved by pivotally connecting the shade bar to the supporting operator or shade support, so that the bar can be re-leveled by raising or lowering the bar against the IG spacer. The follower slides in a track on one side of the IG. The spacer includes an air passageway between the desiccant chamber and the space between IG space, and the hole is covered by an air-permeable patch to prevent unwanted leakage of desiccant into the viewable area.
