This is why I didnt believe it was heterodyning because the frequency I found resonating is FM modulated matching this patent. \ how do this work using FM modulation then https://patents.google.com/patent/US6470214B1/en ChatGPT said: ChatGPT The patent you're referring to, US6470214B1, is titled "Nervous System Manipulation by Electromagnetic Fields from Monitors" and was granted in 2002. The patent describes methods and apparatuses for manipulating the nervous system of a subject by exposing them to weak electromagnetic fields that are pulsed with a frequency near the range of the brain's natural frequencies (typically between 0.5 Hz and 30 Hz, which correspond to different brainwave states like delta, theta, alpha, and beta waves). Key Concepts from the Patent: Electromagnetic Fields and Nervous System Manipulation: The patent discusses the generation of low-frequency electromagnetic fields, which are used to manipulate the nervous system. The fields are intended to induce specific physiological effects, including relaxation, sleep, or heightened alertness, by influencing brainwave patterns. Modulation Techniques: The core idea is that a visual display device (like a CRT or LCD monitor) can emit electromagnetic fields modulated at frequencies that can interact with the nervous system. The modulation can be either amplitude modulation (AM) or frequency modulation (FM), and it is designed to resonate with the natural brainwave frequencies. The modulation frequencies are chosen to be close to the natural frequencies of the brain (e.g., alpha waves at around 8-12 Hz). FM Modulation: In the context of the patent, FM modulation refers to varying the frequency of a carrier wave according to a lower-frequency signal that is in the range of the brain's natural frequencies. This carrier wave could be in the radio frequency (RF) range, and its modulation would result in a spectrum of frequencies that include the desired brainwave frequencies. Application through Monitors: The patent specifically discusses using monitors (e.g., CRT or LCD screens) to generate these electromagnetic fields. The screens are modulated at low frequencies that match or are close to the brain's natural frequencies. This modulation can be achieved through the monitor's refresh rate or by pulsing the brightness of the screen. As a result, the electromagnetic fields emitted by the monitor could potentially influence the viewer's nervous system. How FM Modulation is Applied: Carrier Frequency: The monitor emits a carrier frequency (likely in the RF range) that is modulated by a low-frequency signal within the brainwave range (e.g., 8 Hz for alpha waves). The FM signal modulates the frequency of the carrier wave, causing it to vary slightly around the carrier frequency. Demodulation by the Body: The concept in the patent is that the human body, particularly the nervous system, could demodulate these FM signals naturally. This is based on the idea that biological tissues have nonlinear properties that can respond to varying electromagnetic fields, potentially generating the low-frequency components that directly interact with the nervous system. The modulation in the electromagnetic field might influence neural activity by causing the neurons to fire in synchrony with the modulating frequency. Induced Brainwave Entrainment: The patent suggests that the modulated electromagnetic fields could entrain brainwave activity to match the modulation frequency, effectively altering the subject's state of consciousness (e.g., inducing relaxation or alertness). Nonlinear Biological Response: The patent relies on the assumption that the nervous system or brain tissue can act as a nonlinear medium that "demodulates" the FM signal, extracting the low-frequency component that resonates with brainwave activity.
