Movie black technology

After the meal, Chen Shen and He Changfeng exchanged in the cafeteria for a while, and then they separated.

Go back to your dormitory.

Pushing open the door, inserting the data hard drive into the computer, and carefully checking the signal data inside, before he was completely sure.

In the experiment just carried out, the ten sensors did clearly and completely captured the ten photoacoustic signals generated by the mice.

This is the basis for the next step forward.

Chen Shen breathed a sigh of relief.

It took so long to solve this problem. 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 for the Spring Festival.

Now that the signal has been detected, the next thing to do is to write the signal analysis algorithm and program to prepare for the subsequent human test, and strive to perform signal analysis on the day the signal is obtained.

There is nothing to say about this.

Turn on the system, switch the computer page again, and operate on the keyboard!

While looking at the algorithms and program codes in the system, Chen Shen reproduced them on the computer.

He chose the simplest blood glucose algorithm in the system. After analyzing the signal with this algorithm program, the blood glucose value range of the test object can be obtained.

It's not that he doesn't want to choose other algorithms that parse more information. The reason for choosing this algorithm is that one reason restricts him.

Number of lines of code...

For other algorithms with complex functions, the number of lines of code will increase accordingly...

For example, the algorithm of body image construction has reached the point where he will be bald at a glance.

And things like code are not well known to copy.

This Mediterranean ship ticket should be given to the programmers of the Artificial Intelligence Center.

Therefore, he can only copy the code with the fewest lines of code. Anyway, he only needs to make sure that the signal collected by the human body is usable. You don't need to care too much about the data that is parsed.

Among the information currently published by the system, the least code is the blood glucose detection algorithm.

The algorithm is not complicated, but the specific program code was copied for more than two hours.

It's not that Chen Shen didn't think about optimizing this program, but after studying it, 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 be a code porter once.

He didn't finish the whole procedure until 11 o'clock in the evening.

As soon as it was finished, 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 analysis algorithm of White Mouse is not compatible with humans." Looking at the results on the screen, Chen Shen muttered to himself.

To detect the blood information of the mice, it is possible to make additional adaptations to the analysis algorithm.

In the photoacoustic signals generated by various living bodies, various influencing factors are different from those of humans. For example, the analysis algorithm of the human body may be addition, while the analysis algorithm of the mouse may have to take the road of multiplication.

Naturally, such a situation cannot be analyzed by human algorithms.

This is also a minor shortcoming of photoacoustic scanners. Before the algorithms of other organisms are sound, it is not applicable to non-human life forms.

To perfect these algorithms, a lot of research and experiments are necessary. This is a big project, and there is no systematic guidance.

Destined to be another Mediterranean ferry 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 times.

The members of the photoacoustic research room also gradually returned to the base.

Chen Shen's three experimental assistants also returned to the laboratory.

After hearing that Chen Shen had already carried out the signal acquisition experiment by himself, and it was successful, the three research assistants in Zhouzhuang didn't know what to say for a while.

"What we are going to do today is an experiment to obtain human photoacoustic signals."

Inside the laboratory, Chen Shen was talking to the Zhouzhuang trio, He Changfeng was also on the side.

He left the rest of the team today and came to observe this experiment specially.

Of course, according to his statement, he himself came to help.

"Is anyone willing to be a test subject?"

As soon as Chen Shen's words fell, Zhou Zhuang didn't hesitate at all, and immediately raised his hand.

The other two research assistants saw it and had to give up.

Chen Shen produced an experiment consent form.

"Although in principle, the scanner is unlikely to cause any damage to the body, but for the sake of insurance, let's sign a consent form."

The ancillary conditions of the consent form contain various guarantees after an accident.

However, Zhouzhuang didn't look at it and signed it without hesitation.

The white mouse has been swept by the laser under his nose many times, and he is even less likely to worry about the safety of the photoacoustic scanner.

After signing the consent form, he walked into the laboratory and sat in a chair dedicated to testing.

The other assistant is responsible for operating the instrument outside.

"Are you ready?" the assistant asked Zhouzhuang.

Zhouzhuang made an "ok" gesture.

The assistant controlling the instrument immediately started the scanner.

Squeak~

Under the soft sound of the mechanical arm, the laser transmitter aimed at Zhouzhuang, automatically avoiding the clothes on his body, and quickly scanned the bare skin.

As usual, within two seconds, the signal has appeared on the oscilloscope and converted into detailed data by the converter.

"Did it succeed?" Zhou Zhuang was still asking in the experimental area. When other people responded to him, Chen Shen had already checked the data in front of the computer.

"How about it, is the signal reception complete?" Several other people and He Changfeng all approached.

Faced with a large amount of data, Chen Shen directly took out a USB flash drive from his pocket and said to the assistant:

"Install the program in the USB flash drive, and then import the data just now."

"Ah? What is this?" The research assistant was taken aback.

"I wrote a signal analysis algorithm two days ago that can analyze the blood glucose level in the signal." Chen Shen said, and took out a household blood glucose meter from his bag and handed it to Zhou Zhuang for testing.

He Changfeng immediately said, "Quick, try!"

The research assistant in front of the computer immediately took over the USB flash drive, "Okay!"

Insert the U disk, install the program, import the data, all in one go.

After the data was imported, the host computer started to run wildly, everyone on the scene could hear the sound, and then the result was displayed on the screen.

7.8mmolL

Everyone looked at Zhouzhuang 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:

7.9mmolL
