Abstract: This disclose describes systems, methods and non-transitory computer readable media for controlling operations of an EC device with compensation for the hysteresis effect of the leakage current. A control module, coupled to the EC device, may be configured to develop a hysteresis model representing a hysteresis effect of a leakage current of the EC device, track one or more prior operating histories of the EC device, and transition the EC device to a target transmission level with compensation for the hysteresis effect of the leakage current based in part on a current transmission level, the one or more prior operating histories, and the hysteresis model of the EC device.

Abstract: Various embodiments relate to an electrochromic (EC) device that is structured with surface contour features arranged according to a randomized pattern. For example, one or more conductive layers of an EC device may be structured with such surface ablations. In some embodiments, the randomized ablation pattern may comprise a randomized variation in one or more geometrical characteristics of a group of segments. In some examples, the geometrical characteristic(s) may include a distance characteristic, an orientation characteristic, and/or a shape characteristic, etc. According to various embodiments, the randomized ablation pattern may be configured to reduce diffraction and/or scatter of light incident on the surface ablations as compared to some other ablation patterns.

Abstract: A method for controlling multiple electrochromic devices (ECDs) that have a variable tint profile. The method can include applying an initial test voltage profile to four or more bus bars of a first ECD, producing a first test tint profile in the first ECD in response to the initial test voltage profile, adjusting the initial test voltage profile to produce a first desired tint profile (DTP) in the first ECD, determining first modeling parameters based on the adjustments of the initial test voltage profile, modeling the first ECD based on the first modeling parameters, determining first compensation parameters via the first ECD model determining a first compensated voltage profile (CVP) by modifying the initial test voltage profile based on the first compensation parameters, and producing the first DTP in the first ECD in response to applying the first CVP to the first ECD.

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.
