1. A window comprising:
- a. an electrically-adjustable light transmitter configured to change a light transmissivity responsive to an electric signal, the signal provided to the electrically-adjustable light transmitter being responsive to a geographic location; and
b. a controller coupled to the electrically-adjustable light transmitter and configured to control electric charge provided to the electrically-adjustable light transmitter, responsive to the geographic location.

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:
-
a. navigation system, configured to determine a geographic location; b. a controller coupled to the navigation system; c. an electrically-adjustable light transmitter configured to change a light transmissivity responsive to an electric signal received from the controller, the signal provided to the electrically-adjustable light transmitter being responsive to a geographic location received by the controller; and d. 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 electrically-adjustable light transmitter 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:
-
a. obtaining a geographic location; b. providing a first electrical signal to an electrically-adjustable light transmitter, which is configured to change a light transmissivity responsive to the provided electric signal, the electrical signal being received from a controller, which receives data corresponding to the geographic location; c. 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)
