ABSTRACT

Physiological effects have been observed in a human subject
in response to Stimulation of the skin with weak electro
magnetic fields that are pulsed with certain frequencies near
/2 Hz or 2.4 Hz, Such as to excite a Sensory resonance. Many computer monitors and TV tubes, when displaying pulsed images, emit pulsed electromagnetic fields of Sufficient
amplitudes to cause Such excitation. It is therefore possible to manipulate the nervous System of a Subject by pulsing images displayed on a nearby computer monitor or TV set. For the latter, the image pulsing may be imbedded in the program material, or it may be overlaid by modulating a
Video stream, either as an RF signal or as a Video Signal. The image displayed on a computer monitor may be pulsed effectively by a simple computer program. For certain monitors, pulsed electromagnetic fields capable of exciting Sensory resonances in nearby Subjects may be generated even as the displayed images are pulsed with Subliminal intensity.

The electric field (13) due to the dipole distribution causes a potential distribution V(r)/2 over the Screen and a potential distribution of-V(r)/2 over the polarization disc, where V(r) is nonuniform as given by (11).

the potential distribution V(r)/2 is induced over the screen as

In our model the charge distribution qo is located at the Same place as the dipole distribution, viz., on the plane Z=0 within the circle with radius R. At points on the center line of the Screen, the electric field due to the monopole distri bution qo is calculated in the following manner. AS discussed, the monopoles must be Such that they cause a potential (po that is equal to V(r)/2 over the disc with radius R centered in the plane Z=0. Although the charge distribution do(r) is uniquely defined by this condition, it cannot be calculated easily in a Straightforward manner. The difficulty
is circumvented by using an intermediate result derived from Excercise 2 on page 191 of Kellogg (1953), where the charge distribution over a thin disc with uniform potential is given. By using this result one readily finds the potential

The center-line electric field is the sum of the part (13) due to distributed pulsed dipoles and part (19) due to distributed pulsed monopoles. Although derived for circular Screens, the results may serve as an approximation for other shapes, Such as the familiar rounded rectangle, by taking R as the radius
of a circle that has the same area as the Screen.
For two CRT-type monitors the pulsed electric field due to image intensity pulsing has been measured at Several points on the screen center line for pulse frequencies of /2 Hz. The monitors were the 15″ computer monitor used in the Sensory resonance experiments mentioned above, and a 30″ TV tube. The experimental results need to be compared with the

from (10) to (11) is valid. The following procedures were followed in preparing
pulsed images for the field measurements. For the 15″ computer monitor the images were produced by running the VB6 program discussed above. The pulsed image comprised
the full screen with basic RGB values chosen uniformly as R=G=B=127, with the exception of an on/off button and a few data boxes which together take up 17% of the screen area. The image intensity was pulsed by modifying the R, G,
and B values by integer-rounded Sine functions AR(t), AG(t), and AB(t), uniformly over the image, except at the button and the data boxes. The measured electric field pulse ampli tudes were normalized to a pulsed image that occupies all of the screen area and has 100% intensity modulation for which the image pulses between black and the maximum intensity, for the fixed RGB ratios used. The image intensity depends

Screen emissions also occur for liquid crystal displayS
(LCD). The pulsed electric fields may have considerable amplitude for LCDs that have their driving electrodes on opposite sides of the liquid crystal cell, for passive matrix as
well as for active matrix design, Such as thin film technology (TFT). For arrangements with in-plane switching (IPS) however, the driving electrodes are positioned in a Single plane, So that the Screen emission is very Small. For arrange ments other than IPS, the electric field is closely approxi mated by the fringe field of a two-plate condenser, for the
Simple case that the image is uniform and extends over the

(21) and (23). The resultant electric field in the back is relatively Small, due to the change in Sign in the monopole
field that is caused by the factor Z/Z. Therefore, screen
emissions in front of an LCD can be kept small simply by having the grounded electrodes in front.

But it also has the consequence that pulsing of the chrominance for fixed luminance allows larger pulse amplitudes while staying within the Subliminal pulse regime. Eq.
