Siheyuan: Starting from a fitter

Chapter 242 Designing Medical Instruments
The first person Ah Rong and Li Guocheng met was the director, a handsome middle-aged uncle. After seeing the two of them, his face was filled with smiles.

"Director Hu, this is Mr. Jackie Chan I mentioned to you."

"Aaron, this handsome guy is Director Hu Jinquan hired by our company."

"Happy to meet you".

"Happy to meet you".

"Arong, have you told Mr. Cheng about the plot?"

"Already told."

"Well, Mr. Cheng, considering your identity, the plot has been compressed. There are only two scenes and it was filmed in more than an hour. It won't take up too much of your time."

Li Guocheng clasped his hands and said, "Thank you, Director Hu."

"It should be." Director Hu was opposed to it because he was afraid that Li Guocheng would not be able to serve him well.After getting in touch with him, I found that he was a very kind young man with a very good impression.

"Now we are filming the first scene. The protagonist Zhu Feilong (played by Ah Rong) is surrounded by Qing soldiers. At the moment of life and death, you appear on the stage, wave your hand, hit a piece with a dart, and save the protagonist."

Li Guocheng also thought to himself, why there are no lines.

The three of them came to the scenery shed. There were scenery boards on three sides, mountains and rivers, and in the middle were rockeries made of wooden boards, cloth, plaster, etc., as well as some transplanted small trees.

Good guy, it was all shot in a studio, with almost no real landscapes used.

Let’s not talk about the lighting and the Qing soldiers. Let’s just talk about Li Guocheng. A small shot of jumping from a rockery was NGed more than ten times. The key is the expression. It is either too exaggerated or too rigid.

"Mr. Cheng, your posture and movements are very good. The key is your expression. You can't stare at the camera, and you can't ignore the camera. In addition, your expression must be upright and calm."

"This person is a newbie, can it be done?"

"But don't tell me, that action is so cool and has great physical strength. If you repeat it more than ten times, if it were me, I would lie down long ago."

"She has no acting skills at all."

"It's a pity for his stature and his own nobility."

"Director Hu had no choice but to try a few. Although he was good at acting, none of them had that handsome and free temperament."

. . . . . .

"To shut up!"

"Get out!"

Ah Rong and the director were both angry. How could these guys say this in front of others? Don't we dare to speak loudly without seeing them?Why are you so blind?

As the audience dispersed, Li Guocheng was also a little embarrassed, "Wait a while, I will adjust it."

Li Guocheng was also helpless. He originally thought he would just do a few actions and a few lines, but he never expected that he would always do poorly when facing the lights and cameras.

Close your eyes and clear your mind of all the expressions of all the heroes of later generations.He knew that the main reason why he couldn't do it well just now was because of these impressions.

When more than 20 faces appear in your mind at the same time, it is either difficult to choose or the expressions are superimposed.Li Guocheng just verified them one by one.

Now that his mind was completely cleared, in order to find the feeling, he did Tai Chi on the spot that he had been groping for.

Seeing that it was round and silky, with a clear transition between speed and slowness, which was different from previous Tai Chi movements, the director quickly notified the camera.Unexpectedly, the camera had already started filming.

After completing a set of self-composed movements, my body and mind were fully relaxed.

Start shooting again, once and for all.Because this time he didn't think about other people's expressions, he just kept his mentality and blended into that era, and his expressions were very natural.

Originally, when Li Guocheng modified his facial features, he chose to look upright.With the temperament he has cultivated for many years, the whole action was better than expected.

Taking advantage of the characteristics of the Bird Technique, he glide in the air for a while when he jumped down. Following the technique he used when practicing flying knives, he circled around and raised his hands.

The first shot ended perfectly.

With the experience of the first scene, the second scene went very smoothly. I only repeated it 5 times and it was all completed.

"Mr. Cheng, you are born to act in movies, but it is a pity that you are engaged in business. I look forward to working together again next time." Director Hu enthusiastically complimented Li Guocheng at the end of the second scene.

"Thank you Director Hu for your recognition. Filming is more difficult than making money. I've learned a lesson." Li Guocheng also started a business exchange.

When he walked out of the set, Li Guocheng stared at Ah Rong and said, "From now on, I won't listen to you anymore. Filming is too difficult."

Hahaha, Arong arrived at the parking lot, turned around and walked back.At the same time, he did not forget to laugh at Li Guocheng.

"Wait for me," Li Guocheng threatened Ah Rong's back, and then he also laughed.

Although it was a bit embarrassing today, the harvest was still considerable, which made him dare not look down on the people in the world.I was even taught a lesson vividly: every other line is like a mountain.

After returning home, he made up his mind to work on his scientific and technological inventions honestly.

Last time, I talked with Lao Luo about the domestic medical and health situation. He said that purchasing medical equipment is difficult and expensive, and only a few large hospitals can equip it.

Ask Li Guocheng if he can help purchase some.

And the most in demand are biochemical testing equipment and electrocardiographs.

At that time, the secretary consulted some medical equipment suppliers and found that a fully functional blood cell analyzer cost more than 5000 US dollars, and a bulky electrocardiograph cost 8000 US dollars.

Originally, he planned to design it himself and produce it domestically, but he forgot about it.

In fact, these were too simple for Li Guocheng. He was busy with the work at hand at the time. Now that there are no new tasks in the country, he simply designed some instruments that are urgently needed in the country.

Call Secretary Chen to purchase full-function blood cell analyzers and electrocardiographs from various manufacturers on the market.

In less than half a day, they were all sent to Li Guocheng's special laboratory.

Li Guocheng first disassembled and scanned six types of full-function blood cell analyzers one by one, and combined his understanding of human body blood to design a new full-function blood cell analyzer.

Abandon the brush motor and adopt a DC brushless motor, which has strong power and almost no noise during detection.

As for the electrocardiograph, it not only absorbed the design advantages of several manufacturers, but also designed three electrocardiographs based on its own understanding of the heart, namely a conventional electrocardiograph, a dynamic electrocardiograph and a portable conventional cardiogram machine.

For both types of medical instruments, the control core uses microcontroller KT32F102M and is embedded with an LCD screen for real-time display.External interfaces are divided into two categories: 485 and Ethernet.

Safety regulations and EMC design concepts have been added to the circuit part to ensure that the equipment will not affect personal safety.

These concepts only appeared after the 80s and 90s. They were proposed by Li Guocheng as early as the steel rolling mill laboratory.But until he left, no one at the rolling mill could get started.

Many people regard EMC as metaphysics. They understand it as soon as they hear it but become confused as soon as they use it.

EMC (Electromagnetic Compatibility) refers to the ability of electronic equipment to work properly and coexist with other equipment in an electromagnetic environment.

EMC involves many fields such as electromagnetic field theory, power electronics technology, communication technology, and computer technology. It is a relatively complex technology that needs to consider multiple factors such as electromagnetic wave propagation, interference, and anti-interference capabilities.

Some people regard EMC as a metaphysics. This may be because they believe that the technical principles of EMC are too complex and that conventional methods cannot guarantee the EMC performance of products, making it difficult to understand.

But in fact, EMC is a science and technology, not a metaphysics. EMC involves the properties and characteristics of many electronic devices, including the measurement and analysis of physical quantities such as electromagnetic fields and electromagnetic waves. It is a hard-power technology.

EMC's research incentive is said to be an explosion of Sam's space shuttle.In the 90s, it began to pay attention to electromagnetic compatibility, and it has developed into a discipline until now.

The appearance of the two types of medical equipment is directly molded according to the common industrial aesthetic design ideas of later generations.

The two types of equipment were developed in parallel for two and a half months.
