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

Claim 0:
1. An electrochromic (EC) device, comprising:
an EC film stack; and
conductive layers, wherein:
at least one conductive layer of the conductive layers comprises surface grooves arranged according to a randomized groove pattern, the randomized groove pattern comprising a randomized variation in at least one geometrical characteristic of a plurality of open-loop non-intersecting segments from a non-randomized groove pattern, wherein the at least one geometrical characteristic comprises at least:
a directional orientation of an open-loop non-intersecting segment of the plurality of open-loop non-intersecting segments, wherein the open-loop non-intersecting segment of the plurality of open-loop non-intersecting segments has a shape that is one of a symmetrical sinusoid or linear between endpoints of the open-loop non-intersecting segment; and

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