Dr. Bell wore this on his head, his own invention, and one of his many inventions that he marketed.
Here is a snippet from his bio, he sure sounds like Art Bell's brother, and he was interviewed by him enough times. "He then left the defense sector and began studying with Himalayan Masters. During this time he became internationally known as a contactee to a Pleiadean group of extraterrestrial humanoids whom were here to help the people on earth save themselves from their own destructive tendencies. This group comes from a star system 500 light-years from earth. For this effort the Russian society of cosmonauts (astronauts), awarded Dr. Bell the distinguished scientific progress award."
