This is a Rod Serling type of creation that generates fear and the artist traps himself. It is an invention that should only be used for psychic research but could be very marketable at the beach on a volleyball court. The volleyball team would speak through a headset microphone and their voices would be picked up on a crystal earphone. These headsets would be driven by a solar cell. There is a two way radio element here. There could also be one main power supply. The headset could also be used by a surfer who is out in the sun on L.S.D.* and just wants to hear himself speak. This device could bring him back to reality. *this writer has not done L.S.D advocates its use

Why it's free to use
- Filed December 17, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 17, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 17, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
