Chapter 278: Biological magnetic field detection

After Zhou Yunsheng and Li Hao determined that the company had been transformed into a group company, she walked out of Li Hao's office happily. Discuss with many company executives.
Li Hao has nothing to do now, he continues to translate alien civilization technology.
He took time every night to memorize the materials in the Alien Civilization Library, and began translating technology when he was free during the day.
I don't know what the moonlight contains, I can only watch the moonlight enter the library at night.
He is 100% simulation of the spectral components of moonlight through technical means.
Even in the daytime, the library in the glasses could not be started, and Li Hao could only compromise and seize the opportunity to desperately receive the information at night.
Through long-term practice, Li Hao found that his short-term instantaneous memory ability was greatly strengthened after training.
Li Hao's translation technology is a high-performance motor technology.
He also rejoices that he is lucky to get this technology, and the application of motor technology is too wide.
Whether it is the electric vehicle that their company is currently developing or the intelligent robot that they plan to develop in the future, these projects cannot be separated from the support of motor technology.
While Li Hao was sinking his heart to translate the technology of alien civilization, he suddenly heard someone knock on the door of his office room and woke him directly.
He nodded on the virtual light curtain interface on the desk, only to see that the office door opened immediately.
He saw that Qian Minghua, the director of the biological laboratory medical project team, came to his office.
"Supervisor Qian, is there anything you can do to come to the office?" Li Hao motioned him to sit down and asked with a smile.
After Qian Minghua sat down, he said happily, "General Manager Li, the good news. In order to quickly find biologically active artificial organs, we have developed a biological magnetic field detection technology.
It used to work only after stabilizing the background magnetic field in advance. Now we solve this problem through technical solutions, and can use biological magnetic field detection equipment in the ordinary magnetic field environment.
We also have a result of miniaturizing biological magnetic field detection equipment. Through the integration of the entire device, it can already reach the size of a tablet computer. "
After Li Hao heard Qian Minghua's explanation, his eyes brightened. The biological magnetic field detection device can be used in ordinary environments, and has been miniaturized.
Then it has many uses now, and the use requirements are also rapidly reduced.
The simplest application of this technology is as an effective identification device. Used to verify someone's identity.
Nowadays, the most accurate authentication method is the DNA sequencing method.
However, this verification method requires professional equipment and technical staff to operate. It is impossible to use in ordinary occasions, and the speed of output is not instantaneous, it takes a long time.
Various restrictions require that this technology be used in very narrow places.
Now commonly used are fingerprint, iris and face recognition.
Needless to say, there are too many ways to fake. The iris verification method has a simpler way to deceive, you only need to buy contact lenses or beauty lenses of clear porcelain technology. After simple processing, the iris recognition device can be tricked.
Now this deception method has been widely used by criminals. Li Hao also learned from the news that he knew that his company's contact lenses still had this effect.
Face recognition is based on artificial intelligence technology, and now the most mature face recognition technology belongs to porcelain technology. It can distinguish a person's facial bones.
No matter how makeup or easy-looking, the contours of a person's face and bones will not change unless bone grinding is performed.
But it is a solution to the general public, and it is powerless to deal with some special people.
According to Li Hao, during an internal test. In their Skynet system, the face recognition module was breached by technicians from the China Security Ministry.
This also shows that even advanced face recognition technology may have errors.
But these errors will never appear on biological magnetic field detection equipment. Everyone has its own biological magnetic field.
Li Hao has learned the basic principles of biological magnetic field detection. This belongs to a set of dynamically changing magnetic field parameters, and some magnetic field changes are also random.
The characteristics of the biological magnetic field determine that it will not be copied by other people through technical means.
Of course, this technology has such good effects, so the requirements for using this technology will be very high.
It is precisely because the normal biological magnetic field of the human body changes at any time, it is very difficult to prove that this biological magnetic field belongs to someone.
Li Hao is also curious how Qian Minghua solved these problems.
He also didn't knock side by side, and directly asked Qian Minghua: "The biomagnetic field detection technology of my mind is not difficult to verify that the biomagnetic field is stable.
But to verify the biological magnetic field of the human body, it needs to collect the biological magnetic field information of the human body, which takes a long time.
Because of the confidentiality of this method, I have set up such security protection equipment in my military industry. It takes a long time for him to collect a person's information. "
Qian Minghua took a tablet-sized instrument from his carry bag, 20 cm thick.
He was very proud to say with Li Hao: "General Manager Li, our new generation of this kind of biological magnetic field detector, it collects a person's biological magnetic field in less than one second.
The biological magnetic field of the human body is constantly changing, and it appears to be unstable in the body.
Detecting biological magnetic fields requires solving two major difficulties.
One of the difficulties is that the biological magnetic field of the organism is too weak, and it is even weaker than the electromagnetic signal serving as the background.
The second difficulty is that the biological magnetic field of the human body changes at all times. We must ensure that it can be identified as soon as possible without errors. "
Qian Minghua saw that Li Hao was listening to him seriously, and he continued: "Fortunately, these problems have been solved one by one by our laboratory scientists.
Now Director Du Xianyu puts down his original plan ~ EbookFREE.me ~ and suddenly has an interest in a plant. Our project team does not heal plants, and we are the happiest in the biological laboratory.
Everyone brainstormed and began to ponder the difficulties of biological magnetic fields.
In the end, we really found a solution. The biological magnetic field is too weak to detect the biological magnetic field generated by the human body.
However, we use resonance technology to solve it. Through resonance technology, we can let the detection technology ignore other clutter signals.
The solution to the second difficulty is dramatic. This is inspired by Dr. Li Deren's theory of Chinese medicine.
He found that certain changes in the biological magnetic field are very similar to the human meridian activity.
For example, from 23:00 to 1 is the active time of the liver meridian. At this time, the intensity of human biological magnetic field activity is the lowest.
9 to 11 am is the period during which the spleen is active, and we also find that the biological magnetic field also changes accordingly.
Finally, through a series of experiments, we found that the human body was slightly stimulated by different signals.
Different signals fed back at different times have similar characteristics.
This feature allows us to lock time immediately and analyze based on the transmitted signals to establish a person's biological magnetic field spectrum.
Identifying a person this way has a high success rate. "
After Li Hao heard it, he warmly applauded. He knows that Qian Minghua is easy to say, but they have paid a lot for this result.
