Dr. Gregory Chausovsky (Григорий Чаусовский) is a senior researcher of Psychological Science at the Zaporizhzhya National University in Ukraine. While famous in the Russian-speaking world, he only gained momentary attention in the West a few years ago thanks to his invention of a musical condom. The true depth of his inventiveness was sadly overlooked by English speakers.
Dr. Chausovsky's primary interests (as listed in his bios, here and here) are in: "biofeedback, self-bioadaptive psycho-emotional states, hardware diagnostics and correction of the mental and emotional status of an individual, and electronic neutralization of stress." Dr. Chausovsky describes his work as "технотронные психотехнологии" (or "technotronic psychotechnologies").
His field of study can be classified as positive mind control: the use of mind control techniques (psychotronics, cerebrosonics, psyoptics, etc.) to alter one's own mind for beneficial effects (for example, see my own DePsych utility included with MindGuard). Paranoids should, of course, be wary of devices designed by others to control one's mind, but Dr. Chausovsky work is reproducible by the average paranoid maker, allowing them to be sure their homemade devices are safe. He even states in an interview:
"I do not have any trade secrets. Moreover, I openly publish articles on the website with photos and a detailed description. And there is no problem for anyone wanting to repeat my invention. The copyright is, of course, a profitable thing, but when it comes to health, you can not keep saving invention under the pillow."
