Headliner Sensors?

Does anyone know what these three things are?

http://www.f30post.com/forums/showthread.php?t=723133

Sensors, vents, microphones? I cant find anything in the manual that describes what these are. Thanks!

Not for the microphones. Those are right over your head. Probably for the motion sensor for the alarm system. That's what those are in the center headliner fixture in the E9x.
