A new sort of cloaking device

[Epo]

I have seen some sentences about it in the past, but I'm not sure how it has ended:

What about creating a cloaking device which makes you invisible to scanners, but you're still visible in visual range? (like when you double click on the UI in the left corner in the game)

I think I've seen something about it in one of threads about changing cloaks... but the idea has been awakened in my head.

An interesting idea from @TheUnforgiven
