"No, I'm ...... ......"Hong Tao is bitter in his heart, even if the soup and 'medicine' of the second 'milk' and 'milk' are magical, he can't fight continuously, this Nima is not scientific! But Han Xue's hand has already begun to 'rub' and move, and the sour feeling makes Hong Tao breathe in directly, but he can't say that he has just been blown up by Yuria, so he can only grit his teeth and 'stand up'. ,:。

"Nonsense! You must have something to hide from me, what's wrong with it!" Han Xue knew everything about every sweat 'hair' on Hong Tao's body, and she soon noticed the abnormality, and her eyes began to widen.

"Oh yes, why did I forget this!hahahahaha...... You are really my good 'woman', as long as you are here, I can have infinite creative power, come, let my brother kiss one! I will go to the real yàn room first, you don't want to be beautiful, wait until I go home at night to see how I treat you! hahahaha!! "Just in the flood at a loss, ready to be honest" At the moment of handing over the generation, he suddenly saw the dismantled mouse in his hand, and a thought flashed in his mind, and then the whole person froze, and immediately cheered, hugged Han Xue's head and kissed it hard, then grabbed the mice on the table, stood up and walked out of the 'door'.

"Hey!''pants' zipper......! Neurotic! No, I'll go with you! I'm going to see if you're lying to me!" Han Xue startled Hong Tao's reaction, and it took a long time to react, and quickly reminded Hong Tao to pay attention to her appearance, and then she felt uneasy, and then followed. She has deceived Hong Tao I don't know how many times over the years, and she is almost immune, not only are small tricks useless to her, but she has begun to be immune to many big tricks.

Hong Tao really wasn't lying to Han Xue. Just now, he suddenly remembered a small invention that matched his concept, this idea came from the mice in his hand, and this invention is also a mouse, a completely different mouse from now. Optical mouse!

In fact, this photoelectric mouse is not Hong Tao's invention at all, he is plagiarism, 100% plagiarism! This thing is all over the streets in later generations, but because the time has not yet come, it was chosen by Hong Tao, a reborn person. Of course, as long as Hong Tao does not admit that it is plagiarism. Then this thing is his invention and creation.

The problem is that Hong Tao is not very sure about this, and he does not know exactly when and what month the optical mouse was invented, he only knows that this kind of computer peripheral only entered China in the early 21st century or the late nineteenth century. However, there are many things that have only entered China after a few years, more than ten years, or even decades, and China does not have them, and foreign countries do not have them. So he can't rejoice too soon. He needed to go to the real room and ask the Soviet experts, and then ask Professor Wang to check the information to finally determine whether the invention counted.

On the way, Hong Tao had already roughly drawn a structural diagram of an optical mouse, and these things were all in his memory. When he opened an Internet café in his last life, at the beginning, in order to save money, he held the technical position by himself, from network wiring to building a computer to networking, engraving, and charging servers. And repairing simple equipment damage is even more important every day, especially those consumables. Keyboards, mice, and headphones are the three most common of them, disassembled, assembled, and disassembled, back and forth for several years. He knew what was in the device with his eyes closed.

To put it bluntly, the structure of the photoelectric mouse is simpler than that of the traditional mechanical mouse, which is to use a light-emitting diode as a light source, and pass a pair of guò at an angle of about 30 degrees

The mirror is 'reflected' onto the table. At this time, the imaging sensor perpendicular to the desktop will sample the area illuminated by the diode at a certain frequency, and the sampling information will be received and calculated by a digital signal processor, and then according to a certain algorithm. to get the change in the position of the mouse pointer.

But it's easier said than done! These hardware problems are easy to solve. The only difficulty is this light engine and control chip. Of course, this is mainly difficult for Hong Tao. It is almost difficult for him to get into the sky, because he is still only at the level of using computer software and hardware, and he does not know anything about the deeper technology. But it doesn't matter, I won't be able to do it myself, but others will, aren't those Soviet experts engaged in these things, and now it's their turn to play!

"Did you figure this out?" Professor Wang happened to be in the real room, and since he had these foreign partners, his enthusiasm for research has been even higher, and he has been immersed here almost every day. It's the same as playing mahjong, no one plays with you or the level of the person who plays with you is too low, even if you always win, it's not interesting to play. Now that he has a suitable partner, he simply gave up most of his teaching tasks and began to engage in scientific research wholeheartedly.

"Whims...... I have a lot of mice that are broken, and I tinker with them when I'm fine. Later, I found out that even if it is a mechanical mouse, in fact, the 'fine' positioning inside is also done with a photocell. Later, I pondered, since all the photocells are used, then why bother with another procedure, just use the photocell instead of the trackball. But you know, I didn't even graduate from junior high school, and I don't really understand anything deep. Isn't this I'm going to draw a sketch for you to see, can this thing be realized under the current technical conditions?" Hong Tao said that he loved science very much, if Professor Wang knew that he was 'forced' by Han Xue and Yulia to come up with such a thing, it is estimated that he would have to tear up this broken paper directly.

"It's kind of interesting, your father always says that you are engaged in scientific research, I didn't believe it before, but now I think your father sees people more accurately than me. Ninety percent of scientific research depends on patience, and the most important thing is to not have an excess of 10 percent, and that is inspiration! Sometimes you may not be able to figure out something in your lifetime when you think about it in a down-to-earth manner, but unintentionally such a flash of inspiration is more effective than this life...... Otherwise, you go back to tutor the knowledge of high school, and then come to the real yàn room, and I will take you to learn. Let's not learn those useless things, just specialize in the 'mastery' of this 'door', your father taught you mathematics, and I will teach you electronics, how about it?" Although Professor Wang is not engaged in computers, his field is very close to computer equipment, looking at his attitude, he should have understood Hong Tao's drawings, and he also agreed with Hong Tao's ideas. However, the old man seemed to have forgotten Hong Tao's original intention of coming here, and began to think about Hong Tao's future development.

"That's a must! I'll buy books to read when I go back, in fact, I haven't left it down, I originally planned to 'get' a place to study abroad, and also save some face for my father, otherwise he always has a pimple in his heart." Now that you say that, I think it's 'quite' good, then I won't study abroad, and I'll be your apprentice. "Hong Tao's fooling 'tricks' with the elders is smoother than lying, and now he is starting to use his father's wishes to pressure Professor Wang's construction, and when his father asks him about studying abroad in the future, he can still use Professor Wang's construction to prevaricate.

"Your father is right, but the face is not faceless, I can see it clearly, it is better to not be able to do it or not, our generation will suffer from this good face. However, I support you to go out and have a look, see more to be more knowledgeable, and learn the basic knowledge well, it will not affect your future development, which does not conflict with my proposal. It's nothing more than a few years earlier and a few years later, you are still young, don't worry!" Professor Wang made Hong Tao say very comfortably, but anyone who is a teacher, even if he has only been a teacher, he also hopes that the next generation will make progress every day and have an ideal life every day, and Hong Tao's words are exactly what he likes.

"That's right, I must urge myself not to relax...... Look at this ......" Hong Tao said that the old man was happy, and then pointed to the drawing in Professor Wang's hand, saying that everything else is nonsense, and now he only cares about whether this drawing can be applied to the real thing.

"Oh, by the way, I'm chatting, it's business! I guess it's reliable, but I'll have to ask them for details. Boy, if this thing is done, then your father's face will be beautiful, and I will follow it, don't look at my students, one by one, master's degree, doctorate, it's all 'flower' shelves, and they are not as strong as your drawings! Alas...... "Professor Wang is really old, he has no theme when he speaks, and he digresses when he talks and talks."

Hong Tao couldn't understand a word in Russian, anyway, after Professor Wang took his drawing and got together with a few Soviet experts, he didn't pay attention to Hong Tao again. They flipped through the data, redrew the drawings, and designed the circuit and found the electronic originals on the side, Hong Tao became a waste, and he had to go back to the sofa in the lounge with Han Xue and wait. He waited until it was dark, and he 'smoked' all the two cigars he was carrying, but there was still no one inside.

"Did you really 'get' an invention? I see that they are all busy with your drawings?" Han Xue was 'confused' on the sofa, and when she woke up, she saw that no one had taken care of it, so she ran to the 'door' of the real yàn room and looked inside, and came back to ask Hong Tao.

"That's a must...... Don't look at this professor or that expert, I just don't bother to use that brain, I just want to be Edison for an hour every day, do you know who Edison is?"

"Of course I do, great inventor, hehehe...... Why don't you leave anything alone in the future, just study it every day, and I'll feed you when you eat?" Han Xue's eyes were full of little stars, she, a guy who didn't even finish high school, actually admired science so much, she really responded to that sentence, and she made up for what she lacked. Q
