Chapter 114 Everyone in the audience called it unscientific!
These two technical terms are 'passive magnetic field shielding technology' and 'active magnetic field shielding technology'.

When seeing this term, some people who have knowledge of electromagnetism have a thoughtful look on their faces.

"First, let me introduce the passive magnetic field technology."

While Lin Feng was speaking, a picture of the structure of the second-generation deep sleep aid appeared on the projection screen behind him.

“As you can see, this is the structural diagram of our second-generation deep sleep aid, which is composed of a multi-layer structure.

The outermost layer is a multi-layer high-magnetic permeability metal plate that directly wraps the brain and shields it from external magnetic field interference.

With it, we can shield most of the magnetic field interference and improve the measurement accuracy of the 'ultra-miniature optically pumped magnetometer sensor'."

After hearing Lin Feng's words, the experts and reporters at the scene showed an expression of sudden enlightenment, and then nodded in approval.

After all, although the magnetic field cannot be seen by the naked eye, there are indeed some things that can block the magnetic field.

Of course, to be more precise, it is not that the magnetic field is blocked, but that the magnetic lines of force are returned from the north pole of the high magnetic permeability metal material along the magnetic circuit to the south pole, forming a magnetic loop.

It's like a small lightning bolt striking a person in an iron net, but there is an iron net in front blocking it, and the resistance of iron is lower.

The electric current will only flow through places with lower resistance and will not form a loop, so people in the iron net will not be hurt in any case. This phenomenon is the famous Faraday cage phenomenon!
The same is true for magnetic fields, but the properties of magnetic fields are different from electricity. For electricity, it doesn't matter if the gaps in your net are very wide.

But it is different for the magnetic field. There cannot be any gaps in the magnetic field, and even the metal plate must be as thick as possible to avoid magnetic leakage.

Of course, the second-generation deep sleep aid uses multiple layers of high magnetic permeability metal plates. Several layers of materials are stacked together, and the effect is naturally much better than a single high magnetic permeability material.

However, Lin Feng did not stop introducing at this time. When people nodded gently, Lin Feng continued:

“Passive shielding technology is ultimately a passive defense against external magnetic field interference. No matter how hard you try, it can’t prevent much. And because this thing is worn on the head, the magnetic field below the head cannot be shielded.

Therefore, we introduced active shielding technology, which uses the effect of Helmholtz coils to create a uniform magnetic field to offset and shield external magnetic interference.

However, this Helmholtz coil is not just a coil, but is composed of multiple groups of coils according to the 3D vector field, which can accurately shield the interference of the external magnetic field. "

After hearing what Raymond Lam said, most netizens nodded instinctively, but in fact they had no idea what Raymond Lam was talking about.

In response to this, Lin Feng thought for a moment and then said:

“In addition to hardware shielding, active shielding technology also has magnetic field shielding at the software level.

This software-level magnetic field shielding is done by the artificial intelligence Jarvis blocking and ignoring useless magnetic signals, just like we want to concentrate on listening to someone talking in a noisy environment.

Although this is a bit difficult, after a certain amount of training, the artificial intelligence Jarvis can perfectly block and ignore those useless external magnetic fields.

Ultimately, the three parties can work together to perfectly shield external magnetic interference and achieve ultra-high precision recognition of brain shape and brain wave states.”

"Making love……"

There was warm applause at the scene, cheering for Xingtu Technology.

After listening to Lin Feng's explanation, although people did not quite understand the specific technical principles, they also knew that the defect of the 'ultra-micro optical pump magnetometer sensor' that was afraid of interference from external magnetic fields had been compensated.

In response, Professor Jacobs's face immediately turned ugly, but Lin Feng ignored him.

Lin Feng smiled and said:

"Okay, now that I have introduced the general technology, let me introduce the effects of our second-generation deep sleep aid."

As Lin Feng spoke, the projection screen behind him instantly switched to a new picture, which was showing a picture of the improved effect of the second-generation deep sleep aid.

The first generation of deep sleep aids, deep sleep time is 40% to 45%. The second generation of deep sleep aids, deep sleep time is 65% to 70%!

When people saw the parameters published above, there was an uproar at the scene. People looked at each other with disbelief in their eyes.

"Incredible!"

"real or fake?"

“Is the improvement really that great?”

"If this is true, it's really too strong!"

"This is definitely alien black technology, otherwise how could the improvement be so great?!"

"I thought it would only stabilize at 45%, but I didn't expect it to increase by 65% ​​to 70%. Is this crazy?"

“Oh my god, if this is true, then it means that when we fall asleep, we are in deep sleep for 65% to 70% of the time?!

If this is true, then from now on there will be no one with mental problems anymore, everyone will always be full of energy and vigor!"

"Don't say that. This thing doesn't look cheap at all. It's a bit exaggerated to say that everyone can afford it. I guess many people can't afford it."...

At this time, the experts and reporters on the scene were shocked and couldn't help but start discussing.

Of course, there are also many shocked discussions among netizens on the Internet, with countless netizens expressing their shock and emotion.

This also resulted in the live broadcast room being directly occupied by densely packed barrages of text from various countries, and the video screen could not be seen at all.

There was even a two-second freeze in the live broadcast room because there were so many comments expressing emotion at the same time.

"As you can see in the structural diagram, our second-generation deep sleep aid has a brain wave detection array composed of 50 'ultra-micro optically pumped magnetometer sensors', which provides us with very rich data.

With these data, our artificial intelligence Jarvis can more accurately judge the brain's state and even emotions.

Ultimately, through voice guidance, special sound waves, light guidance, etc., the brain waves are quickly guided to reach the state of falling asleep and deep sleep! "

"Pah, pah, pah, pah, pah, pah..."

As Lin Feng finished his words, the people at the scene applauded again, applauding Xingtu Technology for developing such a great product.

In response to this, Lin Feng waited for the applause to subside for a while before continuing:

"In addition to increasing the proportion of deep sleep time to between 65% and 70%, our second-generation deep sleep aid has also greatly improved its ability to guide people to fall asleep quickly.

In this process, we do not require you to specially train in special meditation and breathing methods. You just need to follow the instructions of the artificial intelligence Jarvis.

If the artificial intelligence Jarvis tells you to exhale gently, you exhale gently; if it tells you to inhale deeply, you inhale deeply; if it tells you to imagine something in your mind, you imagine it...

In fact, because we can detect the brain state and brain wave signals with higher accuracy, the effect of guiding humans to fall asleep quickly is actually more powerful than the effect of deep sleep.

According to our experiments, we found that as long as you cooperate with the command of the artificial intelligence Jarvis, you will do whatever the artificial intelligence Jarvis tells you to do.

The fastest way to feel sleepy is to feel drowsy is within 2 minutes, and the fastest way to feel sleepy is to feel very .... The longest way to last is less than 5 minutes before falling into sleep.

It can be said that this second-generation deep sleep aid is a boon to people around the world who have difficulty falling asleep, and it is also a boon to countless adults.
