A controller is in communication with the geographic positioning system and is configured to limit a range of light transmissivity of the electro-optic device based on a location detected by the geographic positioning system. A manual adjustment control configured to allow a user to adjust the light transmissivity of the window based on the range of light transmissivity provided by the controller. ## Claims ### Claim 1 A window assembly comprising: a window including an electro-optic device configured to limit light transmissivity through the window; a geographic positioning system; a controller in communication with the geographic positioning system and configured to limit a range of light transmissivity of the electro-optic device based on a location detected by the geographic positioning system; and a manual adjustment control configured to allow a user to adjust the light transmissivity of the window based on the range of light transmissivity provided by the controller. ### Claim 2 (depends on 1) The window assembly of claim 1, further comprising: an interface configured to relay transmissivity information to a user. ### Claim 3 (depends on 2) The window assembly of claim 2, wherein the interface relays a percentage of transmissivity to the user and a range of available transmissivity based on the location. ### Claim 4 (depends on 1) The window assembly of claim 1, wherein the controller anticipates a change in a legal range of transmissivity based on a heading of a vehicle, and relays the anticipated change in the legal range of transmissivity to the user and an anticipated time to reach the change. ### Claim 5 (depends on 1) The window assembly of claim 1, wherein the transmissivity of the window is automatically adjusted as the vehicle passes through geographic locations having different legal transmissivity ranges. ### Claim 6 (depends on 1) The window assembly of claim 1, wherein the range of light transmissivity is accessed wirelessly from a remote location by the controller. ### Claim 7 (depends on 6) The window assembly of claim 6, wherein the controller accesses local memory when wireless access to the range limit is unavailable. ### Claim 8 A window assembly comprising: a window including an electro-optic device configured to limit light transmissivity through the window; a controller in communication with a geographic positioning system and configured to limit a range of light transmissivity of the electro-optic device based on a location detected by the geographic positioning system; a manual adjustment control configured to allow a user to adjust the light transmissivity of the window based on the range of light transmissivity provided by the controller; and an automatic adjustment control configured to automatically change the transmissivity of the windows to comply with local requirements in a particular jurisdiction and to comply with preset user preferences. ### Claim 9 (depends on 8) The window assembly of claim 8, further comprising: an interface configured to relay transmissivity information to a user. ### Claim 10 (depends on 9) The window assembly of claim 9, wherein the interface relays a percentage of transmissivity to a user and a range of available transmissivity based on the location. ### Claim 11 (depends on 9) The window assembly of claim 9, wherein the controller anticipates a change in a legal range of transmissivity based on a heading of a vehicle and relays the anticipated change in the legal range of transmissivity to the user and anticipated time to reach the change. ### Claim 12 (depends on 8) The window assembly of claim 8, wherein the transmissivity of the window is automatically adjusted as the vehicle passes through geographic locations having different legal transmissivity ranges. ### Claim 13 (depends on 8) The window assembly of claim 8, wherein the range of light transmissivity is accessed wirelessly from a remote location by the controller. ### Claim 14 (depends on 13) The window assembly of claim 13, wherein the controller accesses local memory when wireless access to the legal range of transmissivity is unavailable. ### Claim 15 A window assembly comprising: a window including an electro-optic device configured to limit transmissivity of light through the window; a geographic positioning system; a controller in communication with the geographic positioning system and configured to limit an allowable manual range of light transmissivity of the electro-optic device based on a location detected by the geographic positioning system; and a notification system configured to notify the user when the range of transmissivity has changed. ### Claim 16 (depends on 15) The window assembly of claim 15, further comprising: an interface configured to relay transmissivity information to a user. ### Claim 17 (depends on 16) The window assembly of claim 16, wherein the interface relays a percentage of transmissivity to a user and a range of available transmissivity based on the location. ### Claim 18 (depends on 16) The window assembly of claim 16, wherein the controller anticipates a change in a legal range of transmissivity based on a heading of a vehicle and relays the anticipated change in the legal range of transmissivity to the user and anticipated time to reach the change. ### Claim 19 (depends on 15) The window assembly of claim 15, wherein the range of light transmissivity is accessed wirelessly from a remote location by the controller. ### Claim 20 (depends on 19) The window assembly of claim 19, wherein the controller accesses local memory when wireless access to the legal range of transmissivity is unavailable.
