An electrochromic device is structured to selectively switch separate regions to separate transmission levels, based at least in part upon different respective sheet resistances of separate conductive layer regions. Sheet resistance of a conductive layer region can be associated with a transmission level to which a corresponding EC stack region can be switched, and a conductive layer with separate regions having separate sheet resistances causes corresponding EC stack regions to switch to different transmission levels. Sheet resistance in a conductive layer region can be adjusted via various processes, including introducing various chemical species into the conductive layer region to adjust a chemical species distribution in the region, where the chemical species distribution is associated with the sheet resistance of the region, heating conductive layer regions to induce oxidation of the region, adjusting the thickness of a conductive layer region, etc.

Controlled switching for electrochromic devices

The present disclosure relates generally to suspension ceiling grids, for example, suitable for holding a suspension ceiling composed of ceiling tiles. The present disclosure relates more particularly to a vented suspension ceiling support beam including an elongate body extending in a longitudinal direction. The body includes a vertical web, and opposing first and second flanges protruding laterally from the vertical web. A vent is formed through the first flange.
