It’s hard to find any information at all on a one “Hendricus G. Loos,” despite the fact that he’s filed multiple patent applications, with success, for apparatuses that deal with the manipulation of the human nervous system via a computer screen or a television monitor. In the abstract, he explains the following,
“Physiological effects have been observed in a human subject in response to stimulation of the skin with weak electromagnetic fields that are pulsed with certain frequencies near ½ 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 concerning thing about this, as the patent application explains, is that even a very weak pulse can have adverse affects on the human nervous system.
He then goes on to describe that pulse variability and strength can be controlled through software, and explains how, with regards to a computer monitor, DVDs, video tapes and more, and also how it can be remotely controlled from another location.
