Abstract
An electrical response of a privacy glazing structure to an applied electrical sensing pulse can be measured, and one or more parameters of the privacy glazing structure can be characterized. The one or more parameters can be used to load one or more drive parameters for subsequent use in an electrical drive signal used to operate the privacy glazing structure. If an electrical drive signal is already in place, the characterized one or more parameters can be compared to one or more parameters characterized at a previous time. If the one or more characterized parameters are different from those characterized at the previous time by more than a threshold amount, one or more drive parameters of the electrical drive signal can be adjusted to a new value.
