You wear a loop antenna array around the neck. The send and receive antenna device generates positive feedback to calibrate where to steer to receive and send brainwave signals.
The brainwave signal need not be decoded, only to be stored and repeated.
Steering array antenna, bent into a loop, to cover a disc area or a confined volume of space.
Stored brainwave signal will have to be modified for playback on another loop calibrated for another person.
Good morning.
