Abstract
Introduction
It has long been suspected that the government has been using satellites to read and control the minds of certain citizens. The use of aluminum helmets has been a common guerrilla tactic against the government's invasive tactics [1]. Surprisingly, these helmets can in fact help the government spy on citizens by amplifying certain key frequency ranges reserved for government use. In addition, none of the three helmets we analyzed provided significant attenuation to most frequency bands.We describe our experimental setup, report our results, and conclude with a few design guidelines for constructing more effective helmets.
Experimental Setup
The Classical | The Fez |
The Centurion |
We evaluated the performance of three different helmet designs, commonly referred to as the Classical, the Fez, and the Centurion. These designs are portrayed in Figure 1. The helmets were made of Reynolds aluminium foil. As per best practices, all three designs were constructed with the double layering technique described elsewhere [2].
A radio-frequency test signal sweeping the ranges from 10 Khz to 3 Ghz was generated using an omnidirectional antenna attached to the Agilent 8714ET's signal generator.
A network analyser (Agilent 8714ET) and a directional antenna measured and plotted the signals. See Figure 2.
Because of the cost of the equipment (about $250,000), and the limited time for which we had access to these devices, the subjects and experimenters performed a few dry runs before the actual experiment (see Figure 3).
The receiver antenna was placed at various places on the cranium of 4 different subjects: the frontal, occipital and parietal lobes. Once with the helmet off and once with the helmet on. The network analyzer plotted the attenuation betwen the signals in these two settings at different frequencies, from 10Khz to 3 Ghz. Figure 4 shows a typical plot of the attenuation at different frequencies.
Results
For all helmets, we noticed a 30 db amplification at 2.6 Ghz and a 20 db amplification at 1.2 Ghz, regardless of the position of the antenna on the cranium. In addition, all helmets exhibited a marked 20 db attenuation at around 1.5 Ghz, with no significant attenuation beyond 10 db anywhere else.Conclusion
The helmets amplify frequency bands that coincide with those allocated to the US government between 1.2 Ghz and 1.4 Ghz. According to the FCC, These bands are supposedly reserved for ''radio location'' (ie, GPS), and other communications with satellites (see, for example, [3]). The 2.6 Ghz band coincides with mobile phone technology. Though not affiliated by government, these bands are at the hands of multinational corporations.It requires no stretch of the imagination to conclude that the current helmet craze is likely to have been propagated by the Government, possibly with the involvement of the FCC. We hope this report will encourage the paranoid community to develop improved helmet designs to avoid falling prey to these shortcomings.

So my tinfoil hat doesn't really work the way it's designed? But I got the design right off the interwebs!
Do you use the Classical, the Fez, or the Centurion?
What happened to the old Tri-Corner Pyramid-shaped tinfoil hat? I thought that was the one.
After a quick skim of this paper, apparently the MIT team has concluded that tinfoil hats INCREASE the effects of the Government Mind-Control Rays, rather than diminish these mind-control effects.
God, I love MIT! Who else could disassemble a professor's sports car and move it piece by piece to a campus rooftop, reassemble it, and leave it with the engine running?
From an e-mail to my List of Basement & Garage Ionizing Radiation Enthusiasts:
========
When you get there, scroll down, the Tinfoil Hat vendor has a rebuttal discrediting the methodology of this MIT study.
Trust no one, not even M.I.T. students.
My first newspaper job when I was a teenager was a few blocks away from the bus station in Washington DC. We used to get about two or three guys a month who wandered in wanting to talk to a reporter about government control signals emanating from their kitchen appliances -- mostly refrigerators and toasters. (This was decades before microwave ovens.)
Every subsequent big newspaper I worked on, ditto, walk-ins or phone calls. Someone needed to alert the media about the government's use of household appliances to control our brains.
I have no idea why this is such a common psychiatric fantasy.
Or maybe it's not a psychiatric fantasy. A fundamental consequence in logic:
Just because you're paranoid
doesn't mean
you're not really being followed.

Cool post you got here. I'd like to read something more concerning that matter. The only thing this blog misses is a few pictures of any devices.

Hiya Katherine Watcerson --
I got devices!
http://vleeptronz.blogspot.com/2009/08/2-machines.html
and check out this device:
http://www.math.sunysb.edu/~tony/tides/usp2-2.html
Katherine, here's a much better photograph of this Device, I took it myself with a disposable film camera.
I LOVE this Device!

... and if you want to peek around in the guts of this Device and see exactly how it does what it does --

I would like to work in a Radio station, It is one of my dreams, so I think that the experience can change my life forever.So I like a lot the photos because a are so funny.
