Sure I can. I've never been to Japan, but I assert strongly that it exists. Plus, I know a whole lot more about electromagnetic wave propagation than I do about geography.
Sensor nets attached directly to the skull allow paraplegics to control artificial limbs. Do not for a moment think that this is some kind of thought reading. This is low-voltage electrical engineering plus a butt-load of software doing a form of image analysis. It is no different (conceptually) than the software that constructs an MRI image or a Hubbel Space Telescope image. By the way, the hardware tech for this has been around since the 50's, and it was quiet enough to give useful results in the 70's. The part that took the extra 30 years was the software algorithms that could extract the desired signals from the soup or fog of all of the other interfering brainwaves.
The key ingredient is the skull cap. It allows 3-D triangulation of a signal. That c.a.n.n.o.t be done from a distance. Across a room, outside a house, down the street, from space - no, no, no, no. As above, the fundamental problem is high school geometry.
