IEEE papers on EEG affected by cell phone, monitor shielding

Hi everyone,
Hope you find this relevant:

There are a couple papers I've been trying to get for
a while and finally have. I'll attach the smaller one.

The first is a review of 'recent' experiments where cell phones or base
stations <http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1306825>
(pdf attached) altered human EEG, especially during sleep. It came out in
2004.
Although it says results are not consistent, there should be enough in there
to worry scientists and engineers, as well as neurologists. IEEE has
largely
influenced FCC guidelines.

The next is an analysis of radiation from an LCD monitor, and some
simple<http://ieeexplore.ieee.org/Xplore/login.jsp?url=/iel5/7008/18905/00875557.pdf?arnumber=875557>
fixes (that involve changes to the internal shielding). The take home
lessons
in terms of fixes are that shields should either be connected to each other
using low impedance means such as "finger stock" (I.e., strips of metal
wider than screws that the manufacturer used) or isolated using a ferrite
choke.
Also, a shielded cable going through a shield should have the shielding
connected
to the shield.

The main source of RF was found to be the main control circuit board. So,
the switch to LED
backlights may not help much unless manufactures do a better job of
designing their circuit boards to minimize unintentional antennas.
