Patent ID: 11947233
Assignee: SAGE ELECTROCHROMICS, INC.
Field: Machine tools (Mechanical engineering)
Classification: CPC G  B | IPC B  G

Claim 7:
8. An apparatus, comprising:
a substrate; and
an electrochromic (EC) device coupled to the substrate, the EC device comprising:
an EC film stack; and
conductive layers, wherein:
at least one conductive layer of the conductive layers comprises surface contour features arranged according to a randomized surface contour feature pattern, the randomized surface contour feature pattern comprising a randomized variation in at least one geometrical characteristic of a plurality of non-intersecting segments from a non-randomized surface contour feature pattern, wherein the at least one geometrical characteristic comprises at least:
a directional orientation of a non-intersecting segment of the plurality of non-intersecting segments, wherein the non-intersecting segment of the plurality of non-intersecting segments has a shape that is one of a symmetrical sinusoid or linear between endpoints of the non-intersecting segment; and

the randomized surface contour feature pattern is configured to reduce at least one of diffraction or scatter of light incident on the surface contour features, relative to the non-randomized surface contour feature pattern that does not include the randomized variation.
