Richie from Boston takes us down a scary rabbit hole, citing the 2001 patent #US6506148 B2, “Nervous System Manipulation by Electromagnetic Fields from Monitors”. The patent contains drawings of a person at close range from an old school TV set with schematics illustrating how EM fields from the television can be used to manipulate the human nervous system.
The patent’s Abstract states: “Psychological 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 1/2 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 embedded 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 certain subjects may be penetrated even as the displayed images are pulsed with subliminal intensity.”
