Yutaka Yoshinouchi has filed a Japanese patent application (JP2008038574) that at first glance appears to cover both Aluminum Foil Deflector Beanies (AFDBs) and Aluminum-Shielded Enclosures (ASEs), but there are some key differences that should allay fears of lawsuits against AFDB/ASE builders and advocates. Here is the official English translation of the abstract:
INVENTION FOR ANSWER COPING WITH MIND CONTROL
PROBLEM TO BE SOLVED: To solve a problem wherein an answer coping with mind control by aliens from the sky is desired because mind control by a vicious Gray Orion interfering with free mind of human beings should never be allowed, and leaving as it is leads to the satisfaction of the aliens watching vigilantly for a chance of earth invasion.
SOLUTION: Indoor defense is carried out by using an irregularly reflecting material for a wall, using a radio wave absorber/lead, and disturbing signal pulses by laser or the like to disturb Tesla wave pulses. Outdoor defense is carried out by wearing a helmet covered with the irregularly reflecting material, a helmet with laser spread around, or a helmet covered with the radio wave absorber/lead. On the other hand, defense is carried out by rotating laser horizontally and obliquely upward from high-rise buildings, parks, facilities, and the like in each area.
First of all, note the scope of the mind-control protection claims only applies to the primitive radio-based technology used by the vicious Gray Orions (who are not related to the psychotronics-using Reticulans, a.k.a. "Greys", whose center of civilization is in the Zeta Reticuli system). The Gray Orions are one of a multitude of Paraterrestrial Entity Factions (PEFs) seeking influence in the Sol system. They are a little-heard-of PEF precisely because of their backwards mind-control technology, which is easily overwhelmed by the psychotronic smog of the Earth's noosphere. Mr. Yoshinouchi must have had some run-in with an agent of the Gray Orions and made a personal enemy to even bother with developing paranoid technology to counter them.
Next note that Mr. Yoshinouchi's invention goes beyond passive deflective shielding and incorporates lasers. As I understand it, the lasers are integral to the anti-mind-control system that he is patenting, meaning that AFDBs/ASEs on their own would not be covered. To the best of my knowledge, no paranoid researcher has thought to use AFDB-mounted lasers to counter Tesla-wave pulses. This truly is an innovative development, even if it will only work on Gray Orion radio signals (and will undoubtedly reveal your paranoid status to government spy satellites).
Finally, note that the patent application specifically calls for "radio wave absorber/lead", not psychotronically deflective aluminum. This obviously exempts AFDBs/ASEs, although lead- or Velostat-based derivative technologies, if used in conjunction with lasers, might fall under the patent's scope.
Unfortunately only the abstract was translated into English. The text of the full description and claims is in image format so I can't machine translate it easily. I would be very interested in a full translation, both to see the details of his unique design and perhaps learn a bit of Mr. Yoshinouchi's history with the Gray Orions.
