Chapter 195: Human Experiments
After ordering the meal, Chen Shen and He Changfeng communicated in the cafeteria for a while, and then they separated.
Go back to your dorm.
Pushing open the door, he plugged the hard drive into his computer, and carefully checked the signal data inside again before he was completely sure.
In the experiment just conducted, the ten sensors did clearly and completely capture the ten photoacoustic signals produced by the guinea pig.
This is the foundation for the next step forward.
Chen Shen breathed a sigh of relief.
It took so long to solve this problem, and after the boxer was built, it was the first time that he encountered a problem that had hindered him for so long, although there were special factors in it.
Now that the signal has been detected, the next step is to write the algorithm and program for signal parsing, prepare for the subsequent human trial, and strive to perform the signal parsing on the day the signal is obtained.
There's not much to say about this.
Open the system, then switch to the computer page, and do it with a single operation on the keyboard!
Chen Shen looked at the algorithms and program code in the system and copied them on the computer.
He chose the simplest blood glucose algorithm in the system, and after analyzing the signal with this algorithm program, he could obtain the blood glucose value range of the test object.
It's not that he doesn't want to choose other algorithms that parse more information, but the reason why he chose this algorithm is that it limits him.
The number of lines of code......
For other algorithms with complex functions, the number of lines of code will increase accordingly......
For example, the algorithm for the construction of body images has reached the point where he will be bald at a glance.
And code is such a thing, as we all know, can't be copied.
This ticket to the Mediterranean Sea is still for the programmed apes of the Artificial Intelligence Center.
So he can only pick the one with the least number of lines of code to copy, anyway, he just needs to make sure that the signal collected by the human body can be used, and he doesn't need to care too much about what the analyzed data is.
Among the information currently published by the system, the blood glucose detection algorithm with the least code is the one.
The algorithm is not complicated, but the specific program code is still copied for more than two hours.
Chen Shen didn't think about optimizing this program, but after some research, he found that the program proposed by the system was already the optimal solution, and there was no room for optimization.
He had no choice but to honestly work as a code porter.
It wasn't until eleven o'clock in the evening that he finished the whole procedure.
As soon as it was completed, he couldn't wait to input the signal data of the mouse on the hard disk into the program for analysis.
[Invalid data]
"Sure enough, the mouse's analysis algorithm is not compatible with that of humans." Looking at the results on the screen, Chen Shen muttered to himself.
In order to detect the blood information of mice, it is possible to make additional adaptive modifications to the analysis algorithm.
In the photoacoustic signals produced by various living organisms, various influencing factors are different from those of humans, for example, the analysis algorithm of the human body may be additional, while the analysis algorithm of the mouse may have to take the path of multiplication.
Such a situation naturally cannot be parsed by human algorithms.
This is also a small disadvantage of photoacoustic scanners, which are not suitable for non-human life forms until the algorithms of other organisms are perfect.
If you want to improve these algorithms, you need to conduct a lot of research and experiments, which is a big project, and there is no systematic guidance in it.
Destined to be another Mediterranean ticket.
As the holidays passed, the relaxed atmosphere inside the base quickly dissipated.
People's footsteps have become hurried again, and it is difficult to see people in the park during non-break hours.
The members of the photoacoustic laboratory are gradually returning to the base.
Chen Shen's previous three experimental assistants also returned to the laboratory.
When they heard that Chen Shen had already carried out the signal acquisition experiment by himself and had succeeded, Zhou Zhuang's three research assistants didn't know what to say for a while.
"What we're going to do today is an experiment to obtain human photoacoustic signals."
In the laboratory, Chen Shen was talking to Zhou Zhuang and the others, and He Changfeng was also on the side.
He left the rest of the team behind today to observe the experiment.
Of course, according to him, he himself came to help.
"Is there anyone who wants to be a test subject?"
As soon as Chen Shen's words fell, Zhou Zhuang did not hesitate at all, and immediately raised his hand.
The other two research assistants saw it and had to give up.
Chen Shen took out a consent form for the experiment.
"Although in principle, the scanner can't cause any damage to the body, but to be on the safe side, let's sign a consent form."
The conditions attached to the consent form include various benefits in the event of an accident.
However, Zhou Zhuang didn't even look at it, and signed it without hesitation.
The guinea pig has been swept by a laser under his nose for an unknown number of times, and he is unlikely to worry about the safety of the photoacoustic scanner as a human.
After signing the consent form, he walked into the lab and sat down in a chair dedicated to testing.
The other assistant is on the outside to start the equipment.
"Are you ready?" The assistant asked Zhou Zhuang.
Zhou Zhuang made an "ok" gesture.
The assistant who operated the instrument immediately activated the scanner.
Chirping~
With the soft sound of the robotic arm, the laser emitter was aimed at Zhou Zhuang, automatically avoiding the parts of his body that were wearing clothes, and quickly scanning the exposed skin.
As usual, in just two seconds, the signal appears on the oscilloscope and is converted into detailed data by the converter.
"Did it work?" Zhou Zhuang was still asking in the experimental area, and when the others replied to him, Chen Shen was already checking the data in front of the computer.
"How's it going, is the signal reception complete?" Several other people, as well as He Changfeng, leaned over.
Faced with a large amount of data, Chen Shen took out a USB flash drive directly from his pocket and said to the assistant:
"Install the program in the USB flash drive, and then import the data just now."
"Huh? What is it? The research assistant was stunned for a moment.
"Two days ago, I wrote a signal analysis algorithm that can parse the blood sugar value in the signal." Chen Shen said, and took out a home-type blood glucose detector from his bag, handed it to Zhou Zhuang and motioned for him to take the test.
He Changfeng immediately said: "Quick, try it!" â
The research assistant in front of the computer immediately took the USB flash drive, "Okay! â
Insert a USB flash drive, install the program, import data, and all in one go.
After the data is imported, the computer's main unit starts to run wildly, and everyone in the scene can hear the sound, and then the results are displayed on the screen.
ă7.8mmol/Lă
Everyone looked at Zhou Zhuang at this time.
The blood glucose meter in his hand had just been put down, and he showed everyone the results on the blood glucose meter:
ă7.9mmol/Lă
