First Claim
Patent Images
1. A network of window assemblies, each comprising:
- at least one electrochromic (EC) pane and at least one additional pane;
a spacer separating the at least one EC pane from the at least one additional pane, wherein the spacer is provided proximate perimeter regions of the at least one EC pane and the at least one additional pane, where the at least one EC pane and additional pane, together with the interior surfaces of the spacer, form an interior space therebetween;
a primary seal between the spacer and the at least one EC pane, and between the spacer and the at least one additional pane,a secondary seal zone around the outer perimeter of the spacer, between the at least one EC pane and the at least one additional pane; and
a window controller configured to control said at least one EC pane of the window assembly, wherein the window controller is positioned at least partially in the secondary seal zone.

Abstract
Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.
