Coquettish Rebirth

.

spn "Old man, what are you going to do? Tell me the truth, and if you find another way, are you confident that you can finish it in half a year?" Jia Hongjian asked the old man. "Why not? Isn't it just a corded mouse? Don't you think we haven't studied it before?" The old man rolled his eyes at Jia Hongjian while eating dinner. "Ken!" On the other side of the table, the gray-haired old lady Olridge called out her husband's name.

When she shouted like this, Olsen's temper immediately improved a lot. Seeing the old man sighed, he said to Jia Hongjian a little more kindly, "We used to study it in the 80s. Wired mouse, but at that time I found that infrared rays were unreliable, the positioning was too imprecise, and it was not friendly to business users. After all, many business users also need precise positioning when doing report and picture design, and fast and accurate positioning can help increase labor. Productivity. Later, we have been researching other methods. At the end of the 80s, we developed a 27mhz frequency radio frequency wireless mouse, but later found that the power was too large, the power consumption was too high, and it was not practical. It was transferred to Logitech, and they made a mouse..."

Yo?This old man studied these things when he was in e?Jia Hongjian really doesn't know much about wired mice. After all, he is not a professional, not even an engineer. He is just a consumer who is more interested in hardware, and in other aspects of the case. Rather fanatical and feverish, he really didn't have much research on this mouse or something.He has never heard of 27mhz technology! "But these patents should be owned by e, right? And they have been transferred? Are we not easy to use?"

That's right, this old man used to be the boss of e.Even if he developed the wireless mouse technology by himself, as long as he is in the position, the result is considered a work result, which theoretically belongs to the company!So after he resigned, he shouldn't infringe on the patents of the previous company, even if he researched it himself before, such things can easily be sued by the old employer!

At this time, the old man smiled and explained, "There is no patent. This 27mhz frequency is the line frequency of many industrial and medical supplies, called the sm frequency band. This frequency band is basically reserved by various countries for their own countries to use for industry. , Line frequency band for medical and scientific research. So this frequency band itself does not require any license fees. It is free to use. And no one has applied for a patent for this frequency band, so basically it is enough to design a chip for this frequency band , but later found that although this frequency has relatively little interference, there are not many other line frequencies in daily life that will interfere with this frequency band. But this frequency itself has a short transmission distance. It is only 6 feet. That is, more than 18 meters, and The power consumption is too high, and the two batteries will run out of power within a few days. So we gave up this technology. However, I can tell you here that when I was still in office, I just got a new idea technology, but I have just conducted a prototype test myself, and before I have time to announce it in the company, something... happened. So, I still have stock in my hand...”[

Yo?There is such a thing?Jia Hongjian immediately asked curiously, "My lord, what technology are you hiding?" Then I heard the old man Olsen say very proudly, "It's a technology of another frequency band, 24GHz frequency band line transceiver. , the 24ghz and 27mhzyyng are also in the sm frequency band. The simplest example is the cord phone. This frequency band is in the 24ghz frequency band. Therefore, as long as the chip design of the line phone meets the regulations, there is no need to pay any patent fees, and there is no need to It can only be used after obtaining any frequency license. We selected the frequency and then made a non-network solution. This solution can greatly reduce power consumption and also supports sleep, which means that the mouse and keyboard do not need to yyng with 27mhz every time It is transmitting signals all the time, but when the mouse and keyboard are not moving, the chip can automatically enter the sleep standby state, so that it can support a month of use with two batteries installed. Of course, the supported distance is also farther. What I like is that this frequency is free in most countries in the world, so there is basically no broadcast cost..."

Well?There is such a thing?etc!The PHS technology of Huaxia Hi-Tech is the local telephone technology, which evolved from this kind of corded telephone... Oh, yes, it seems that Ni Guangnan and the others have said that they have applied for another frequency band, so it should be possible in this way. There will be no signal interference... Just as Jia Hongjian was thinking, he heard the old man continue, "But this 24ghz thing has the only downside, that is, it needs an infrared sensor. The receiver, although this receiver does not use the xy two axes, it has to be relatively large... Generally speaking, it is about the same size as a mouse, and it may be made smaller and smaller due to technological progress in the future..."

What?receiver?As soon as the receiver was mentioned, Jia Hongjian thought of the line mouse of later generations!The wired mice of later generations basically need a receiver!Around 2010, the receivers of that line of mice were quite small, basically a usb socket with a button-sized stuff added behind it.When using a wired mouse, just plug the receiver into the computer, and the wired mouse can be used with batteries.If you need a receiver for both of them, is the 24ghz line of this line the stuff of the mouse in later generations?After all, things like cable network cards are as big as a lunch box in this era, but casually made in later generations will be the same size as the receiver of the cable mouse. This is probably the reason for technological progress!If so, this ms company may be the first to develop a cheap wired mouse for future generations?

If it is really the stuff of later generations, then the accuracy and stability of this thing can really be expected!Moreover, if it is really the kind of wire mouse of later generations, then any infrared wire mouse can really be thrown aside!Now, Jia Hongjian finally understood why the old man insisted on doing it himself instead of improving the infrared mode, but could the old man really do it in half a year?

For this, what did the old man answer, "In general, the problem should not be too big. The basic things have been studied a few years ago, but they just haven't been done. At that time, I felt that the receiver was too big. I thought about it in a few years. Look, if we do it now, it is estimated that the overall receiver will not be much smaller than the mouse. I think if it is not possible, I will put it inside the machine, and then I will leave an antenna out, and the keyboard is directly near the base of the monitor. Just put a receiver on it..."

Since the old man said so, of course Jia Hongjian believed it. "But old man, why didn't you explain it clearly to me on the phone?" Jia Hongjian asked eagerly.If he had asked clearly on the phone back then, he wouldn't have made a special trip to America. "I just received an invitation from Ericsson. I would like to ask our ms to study Bluetooth technology together. I am wondering whether to use 24ghz or Bluetooth. You are in a hurry to use infrared. Of course I will not agree. ..." The old man curled his lips in a strange temper and said.Seeing what he meant, it was obvious that others could only stroke him along his fur. If he was beaten, not only would he not go away, but he would also walk backwards in that posture.

But the bluetooth in the old man's words caught Jia Hongjian's attention, "Bluetooth?" he asked hastily. "That's right, Bluetooth. In order to develop wireless communication, our e once cooperated with Ericsson. After I left e, Ericsson made it by itself. I heard that they have made some achievements in the past few years, and they are going to pull bm Manufacturers such as Toshiba, Panasonic, and Toshiba came together to make standards, and took care of the face of the past, so they called me. I thought that there are few people now, and there are not many things in this area, so I didn’t agree..."

wipe!The bluetooth technology of later generations is only now beginning to design specifications?Then Huaxia Hi-Tech and Jia Hongjian must participate in this kind of thing!Isn't it said that first-class manufacturers make standards?Although this statement fooled many manufacturers, Huaxia Hi-Tech did not participate in one or two standards, so it would be embarrassing to say it!

"Participate! We must participate!" Jia Hongjian said immediately.But who knew, the old man snorted and retorted: "How do we participate? Intel develops semiconductor chips, BM and Toshiba develop interfaces, Ericsson develops common protocols, what do we develop? Responsible for production?"

"That said, Huaxia Hi-Tech is also a telecommunications giant in the Chinese market! We provide all the program-controlled switches in China! We have also defeated Ericsson, Nortel and other companies! We are in charge of the Chinese region, can't we?" At that time, Jia Hongjian was not happy at all. Although Huaxia Hi-Tech is not well-known in the world, in China, it is really the role of Buddha blocking and killing Buddha!

"Then what do you mean? Is it 24ghz or bluetooth for the wired mouse?" The old man didn't understand what Jia Hongjian meant. It's next year and the next year, can you wait in time? Isn't it because the time is not right that I choose not to agree?"

"Let's occupy the hole first. We can develop 24GHz first, and we can use Bluetooth later! It's better to have the status of a founding member than to be licensed!" Jia Hongjian said excitedly!That's right, if there are some patents of Huaxia Hi-Tech in this future bluetooth headset or something, then just thinking about it will be enough to YY!Just thinking about it can fuel a nationalist pride plot!
