Connection apparatus and methods for communication with movable electro-optic window systems

A vehicle apparatus configured to selectively position and enclose an opening formed in at least one panel of a vehicle, the apparatus comprising:

• a sliding glass panel comprising a first electro-optic device comprising a first plurality of independently controlled dimming zones in communication with a control circuit of the vehicle;
• a fixed glass panel comprising a second electro-optic device comprising a second plurality of independently controlled dimming zones in communication with the control circuit of the vehicle;
• at least one light sensor configured to detect a light intensity map of a passenger compartment of the vehicle;
• a positioning mechanism configured to slidably position the sliding panel along a positioning track between an open position and a closed position;
• and
• a control connection configured to transmit control signals between the control circuit of the vehicle and the electrical device, wherein the control connection extends from a portion of the vehicle to a connection interface of the electrical device, wherein the control connection is configured to communicate a control signal to adjust a transmittance of each of the first plurality of dimming zones and the second plurality of dimming zones in coordination in both the open position and the closed position, wherein the transmittance is controlled through the first plurality of dimming zones and the second plurality of dimming zones limiting lighting imbalances identified in response to the light intensity map of the passenger compartment.
