[0008] However, while suitable for the corresponding structure, the electrical drive signal provided by this driver may not be suitable for providing an appropriate electrical drive signal for other structures such as replacement structures
Also, while the electrical drive signal provided by the driver may be suitable for the structure when first installed, driver characteristics may change based on several factors such as age, environmental operating conditions, etc.
Therefore, the electrical drive signal provided by the corresponding driver may not always be suitable for the structure

Embodiment Construction
[0030] In general, the present disclosure relates to electrical control systems, devices and methods for controlling optical structures with controllable light modulation. For example, an optical structure may include an electrically controllable optically active material that provides controlled switching between a privacy or scattering state and a visible or transmissive state. An electrical controller or driver can be electrically coupled to the optically active material via an electrode layer defining the optically active material. An electric drive may receive power from a power source and regulate the power received from the power source, for example, by changing the frequency, amplitude, waveform, and / or other characteristics of the power received from the power source. An electrical driver can deliver a conditioned electrical signal to the electrodes. Additionally, the electrical driver may alter the conditioned electrical signal delivered to the electrodes and / or cea...

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.
Description
[0001] Related Matters [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 840,026, filed April 29, 2019, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates to structures comprising electrically controllable optically active materials, and more particularly to actuators for controlling electrically controllable optically active materials. Background technique [0004] Windows, doors, partitions and other structures with controllable light modulation are gaining popularity in the market. These structures are often referred to as "smart" structures or "private" structures because of their ability to transition from a transparent state in which a user can see through the structure to a private state in which viewing through the structure is prohibited. For example, smart windows are used in high-end cars and homes, and smart partitions are used as walls in office spaces to pr...
