Abstract: 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.

Abstract: 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.

Abstract: An electrochemical sensor and method for using such a sensor to monitor signals generated by biological cells. The sensor comprises a first well for receiving a culture medium including biological cells, the first well including a working electrode a portion of which is exposed to any liquid introduced into the well. The exposed surface is capable of supporting a layer of biological cells. An adjacent second well receives an in situ reference electrode or can receive an inserted electrode, the two wells being separated by a wall. The wall is arranged such that, if the first well is filled with an electrochemically conductive culture medium to a first level sufficient to immerse the working electrode, and the second well is filled with an electrochemically conductive culture medium to a second level, electrochemical continuity is established between the liquids within the wells.
