Mirror Complexity (0 comments)

I dropped my car off for an oil change at the local Subaru dealership last summer and when I picked it up, the rearview mirror was cracked. The dealership replaced it for free, and shortly after, I found a piece of the old mirror's plastic housing underneath my seat. It had four patent numbers printed on it; I looked them up this morning and learned quite a bit about how my auto-dimming rearview mirror with integrated compass works.
- 5255442: Vehicle compass with electronic sensor
- 5532092: Edge raggedness and background removal by post development member
- 5644351: Thermal gradation printing apparatus
- 5802727: Compensation system for electronic compass
I had no idea it was so complicated.
