First Claim
Patent Images
1. A window comprising:
- an electrochromic device attached to a side of at least one glass panel, the electrochromic device being configured to change a light transmissivity responsive to an electric signal provided to the electrochromic device; and
a controller coupled to the electrochromic device, the controller being configured to control the electric signal provided to the, electrochromic device responsive to a geographic location of the window.

Abstract
An electrically-adjustable light transmitter changes its light transmissivity responsive to an electric signal. By applying the electrically-adjustable light transmitter to a window and thereafter changing the electric signal to it, a window can be tinted and un-tinted. Jurisdictions that prohibit tinted vehicle windows are listed in a data base. A current location determined by a GPS is compared to data base entries. If the location is within an area where tinted windows are prohibited, a controller automatically un-tints the windows, or reduces the window tint to comply with applicable local laws.

11. A geographic location-responsive tinting window comprising:
-
navigation system, configured to determine a geographic location; a controller coupled to the navigation system; a glass window panel; an electrochromic device applied to the glass window and coupled to the controller, the electrochromic device being configured to change light transmissivity responsive to an electric signal received from the controller, the electric signal received by the electrochromic device being determined responsive to a geographic location received by the controller; and a data base of window tinting rules for a plurality of jurisdictions, the data base being accessible to the controller; wherein the controller is configured to receive a location from the navigation system, determine whether the location is within a jurisdiction having a window tinting rule, and, if a window tinting rule for the jurisdiction is located in the data base, adjust the electric signal provided to the electrochromic device responsive to the window tinting rule for the jurisdiction. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of adjusting a window tint responsive to a geographic location, the method comprising:
-
obtaining a geographic location; providing a first electrical signal to an electrochromic device which is attached to at least one glass panel and which is configured to change a light transmissivity responsive to the provided electric signal, the first electrical signal being received from a controller, which receives data corresponding to the geographic location; obtaining a window tinting rule, from a data base of window tinting rules for a plurality of jurisdictions, the data base being accessible to the controller. - View Dependent Claims (18, 19, 20, 21)

22. An electrically-powered vehicle comprising:
-
an electrochromic device attached to a window of the electrically-powered vehicle, the electrochromic device configured to change a light transmissivity responsive to an electric signal; and a controller coupled to the electrochromic device and configured to control the electric signal provided to the electrochromic device responsive to at least one of;
a geographic location of the vehicle and an interior cabin temperature of the vehicle.
