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.

Abstract: A method of controlling an electroactive device can include operating the electroactive device at an operating parameter for a first period of time, applying a switching voltage having a first magnitude and a first polarity to the electroactive device for a second period of time, and applying a step-wise overshoot voltage having a second magnitude and a second polarity to the electroactive device for a transition period of time. The first magnitude can be greater than the second magnitude, and the first polarity can be the same as the second polarity. The method can also include applying a reverse overshoot voltage having a third magnitude and a third polarity to the electroactive device. The third polarity can be the opposite the second polarity.
