I noticed that there is a stripe along the upper edge of both forward windshields in the Embraer E-Jets:

I tried to find a better picture, but couldn't find anything closer. This YouTube video clearly shows the stripe several times:

What is this stripe used for? The only thing I can think of is window heating, but these elements usually look quite different, as can be here: What is this pattern on the A350 front window?

It's a heater bus bar. In fact, the Q/A about the sensor loops that you linked has a great example of the same if you scroll to the bottom of the best answer.

  • So there should be another of these at the bottom (probably hidden behind the glareshield) and then current flows between them for heating? – Bianfable Mar 25 '21 at 15:51

    @Bianfable Of course you're right, in fact you can see them from the outside: https://i.ytimg.com/vi/HEWumjfD6w4/maxresdefault.jpg – zaitcev Mar 25 '21 at 15:56
  • Having never been in the cockpit of an Embraer E-Jet, I would have guessed it was a rod to move the sun shade left to right on to adjust for the angle of the sun. – FreeMan Mar 26 '21 at 17:32
