Being an expert in ultrasonics/frequencies, I can say that this is something that is in the realm of possibility. It is, but no company name. No accompanying website, no nothing so far. Well, it just looks shakey.
Obviously, they have money belts in the background who already knew about this black box, and feel that it works. This is in my opinion.
So bottom line, this deal, continues to be strange, and get even stranger.
