Abstract: An apparatus can include an electrochromic device configured to be maintained a continuously graded transmission state. When using the apparatus, the electrochromic device can be switched from a first transmission state to a continuously graded transmission state and maintained in the continuously graded transmission state. The current during switching can be higher than current during maintaining the continuously graded transmission state. In an embodiment, the grading can be reversed to provide a mirror image of the grading. In another embodiment, at least 27% and up to 100% of the electrochromic device can be in a continuously graded transmission state. The control device can be located within an insulating glass unit, adjacent to the insulating glass unit, or remotely from the insulating glass unit. In a further embodiment, a gap between bus bars can be used to form a portion of the electrochromic device that can be continuously graded.

Abstract: A method can be used to control the operation of one or more non-light-emitting, variable transmission devices. In an embodiment, a method of operating a plurality of non-light-emitting, variable transmission devices can include receiving requests for requested visible transmittance for the non-light-emitting, variable transmission devices; determining operating parameters for the non-light-emitting, variable transmission devices; and operating the non-light-emitting, variable transmission devices at the operating parameters, wherein the operating parameters for the non-light-emitting, variable transmission devices are different. In another aspect, the method can include operating the non-light-emitting, variable transmission device at a first operating parameter for a time period, wherein the operating parameter corresponds to an intermediate visible transmittance; generating a characterization parameter based at least part on the voltage and current measurements that are obtained during the time period; and controlling the non-light-emitting, variable transmission device period based at least in part on the characterization parameter.
