Mind reading/mind control

[Spicer, John]

This is VERY bad science, so I hope Owen posted it tongue in cheek.=0A=
=0A=
To do this sort of thing properly, as we do here where I work (not me perso=
nally though) you need a lot of very expensive test equipment, properly cal=
ibrated, a model of the human head, a certified anechoic chamber, etc.  (Or=
 have we been conned by the test gear manufacturers?)=0A=
=0A=
See http://www.ce-mag.com/archive/03/01/miller.html for an article by a cha=
p from a test house; we are on the design side, mobile phones amongst other=
 things, but do exactly the same, as our designs are going to get tested ev=
entually.=0A=
=0A=
So, at certain frequencies, the foil hats amplify the signal; I want some o=
f that, then I can finish my perpetual motion machine!  This almost certain=
ly caused by reflections from nearby objects, that happen to cause construc=
tive interference at particular frequencies.  That's why we use the very ex=
pensive anechoic chambers.=0A=
=0A=
If you stick a radio transmitter next to your ear, some power is bound to b=
e absorbed; there are prescribed limits.  That's why we design the antennas=
 in mobile handsets to minimise the absorption and test that they meet the =
requirements.  (Also, being mean engineers, we don't want to waste the powe=
r, we want to use it for communicating.)  Each handset gets an SAR rating; =
the lower the better.  The manufacturers have to publish these.  Is it safe=
?  Not my area; FWIW I'm happy to use GSM occasionally, but I wouldn't have=
 one stuck to my ear six hours a day.=0A=
=0A=
The bit about frequency allocation is complete balderdash (there's another =
word beginning with B that is more appropriate.)  See http://www.ntia.doc.g=
ov/osmhome/allochrt.pdf for US civil allocations and http://www.roke.co.uk/=
download/datasheets/UK_Radio_Frequency_Allocations.pdf for UK civil; the of=
ficial UK allocations can be found on the OFCOM website, including military=
 use http://www.ofcom.org.uk/radiocomms/isu/ukfat/fat2004.pdf, US ones on N=
TIA somewhere, I've a feeling the military ones are elsewhere.  Very little=
 of the spectrum is reserved for military use.=20=20=0A=
=0A=
Just to complicate things; there are a whole raft of organisations involved=
 with the use of radio spectrum apart from the above national regulators, e=
.g. ITU-R, CEPT, ERO, FCC, ETSI, etc.  And because in general countries hav=
e neighbours, they can't just assign spectrum to their military, willy-nill=
y.  This is all done by very slowly moving international agreement.=0A=
=0A=
Oh, BTW, don't confuse allocations with assignment and actual use.  Just be=
cause a band has been allocated, does not necessarily mean it has been assi=
gned to a user, nor that the assigned user is actually using it.  1.2 GHz t=
o 1.6 GHz contains the various GPS transmissions, and soon will be joined b=
y Galileo, the European equivalent; these signals are only just above the a=
mbient radio background noise.  There are all sorts of other terrestrial bi=
ts and bobs, with much higher powers.=0A=

The link below is to an MIT empirical study into the attenuation of RF=0A=
emissions by aluminium hats. Contrary to expectations and despite the=0A=
testing of several different styles of that, it was discovered that,=0A=
regardless of design, the hats actually act as an amplifier rather than as=
=0A=
an attenuator at certain frequencies. This observation is common to all the=
=0A=
styles of hat tested. Also, the frequencies at which an increase in the=0A=
radiated power is observed are all either reserved for US military use or US=
