There are already treatments for migraine using TMS:

If TUS is more precise, and can be made to do similar things to the brain, it's possible we'll see it also used to treat chronic migraine.
I'm not a candidate for TMS migraine treatment, since (thankfully) mine are not severe or frequent enough and (also thankfully) they seem to be diminishing with age.
NSAIDs are hit-or-miss for me with migraines, unless I take an ibuprofen (neither acetaminophen nor aspirin work for me at all) before the migraine progresses. It's likely that the generic ibuprofen you have does contain the active ingredient, but it is probably a different (cheaper) formulation.
Lucid dreaming is a relatively simple thing to learn to do for some people. I can see how it would be possible to use a device like this as a shortcut to learning the technique, since that requires a lot of trial and error and practice. One of the existing shortcut techniques for lucid dreaming is an external stimulus, which, if you don't have a fancy TUS gizmo with machine learning, is a less-fancy, non-brain-stimulating device (which can be a person watching you sleep or any number of devices that have been available for decades) that is capable of detecting your entry into REM sleep and stimulating you.
