These were made in China. Used to cause and brainwash communism. Seriously they made children as young as 4 years old wear them in schools. It monitored the child. They sent shocks to the child who started day dreaming, showing less brain activity. They have lights on them, Green, Orange, and Red. If it fell out of Green activity, shocks happened. Red they were further punished. The children in school had to register green activity. It had the highest statistic for best grades and memory. Same devices. Monitors brain activity. The communist regime used it, sending data, and cycles compared to grades, back to the hive.

They also used them to indoctrinate communism making anybody accused go to these schools with them. Sends mild shocks to your brain if it wanders by having decreasing activity, if it cannot repeat any memory, and if it fell into red, they'd, in the schools publicly humiliate them, telling the class the child is retarded, sending them into corner and worse, combined into the shocks. The lights everybody can see except the wearer. It was fixed to their heads.

Zap, zap, zap. Shocking you. For not have healthy brain activity. What they considered healthy brain activity. Basically a green light they had to focus on maintaining. If the lights changed the shocks got worse. Meant posture, no decreased vitals, also god knows. They weren't accurate because they might have stopped it, in the majority used. It came out recently prior to Covid in quite a few schools there.
