Coquettish Rebirth

Of course, the experimental results they made based on such a hint from Jia Hongjian may not be complete. "Maybe speaking at different volumes, the microphones on the top and bottom will have different volume differences, so in the end it may be necessary to define more detailed standards for distinguishing human voices and noises.But anyway, such a solution proposed by Jia Hongjian is quite admirable and amazing!That's right, although many detailed problems still need to be resolved, overall speaking, Jia Hongjian's idea really has an epoch-making effect!This is really a cheap and messy plan, and it has achieved a plan that others have to spend millions of dollars to study!

For such a plan, if the Americans come up with practical results, they may sell a set of solutions, and they will need to charge a licensing fee of more than ten dollars for a mobile phone, plus the cost of purchasing various chips. A price increase of $50 is very normal!And what about Jia Hongjian's solution?That's completely different. Add an extra microphone, add an extra chip, and burn a small judgment software into the chip, and everything will work.Such a price, let alone 50 dollars, can be done with 50 RMB!How big is the difference?It can be said that if 50 yuan can be done, then such a function can be added to all Huaxia Hi-Tech mobile phones without changing the product price!Then there is the core competitiveness compared with other companies!If other companies want to achieve similar results, the price of their mobile phones will definitely increase. If they don't use it, then they will have no way to compete with Huaxia Hi-Tech, at least one bright spot will be missing.From such a point of view.It is definitely the core competitiveness!

"Mr. Jia, we need to apply for a patent as soon as possible! The whole world must apply for a patent!" Ni Guangnan didn't care about the details of the noise reduction technology at this time, and now he really knows the awesomeness of such a patent!When other families want to reduce noise, they think of various complicated methods, but the method proposed by Jia Hongjian is simple and easy to use, it can be said that it is as simple as piercing the window paper.Naturally, Jia Hongjian can think of it now, and maybe the Americans will think of it at some point, or even a Japanese inventor can think of it with a random slap on the head someday, so why don't we register as soon as possible?Isn't this registration our own thing?This is simply a golden mountain from heaven!

"Okay, then let's apply first!" Jia Hongjian looked at Ni Guangnan seriously.Also nodded.So the entire Huaxia Newsletter started to rush to apply for applications from all over the world.To apply for patents all over the world, the first thing to do is to search for patents on similar technologies in the United States and the World Intellectual Property Organization!This search really opened Ni Guangnan's horizons - first of all, the nms company in the United States has really developed a hardware noise-canceling gadget.But they are such a stuff.It relies on the modification of microphones, mobile phones and telephones.To achieve the effect of noise reduction, in short, it is the so-called "echo suppression system"!

Such an "echo suppression system" was first used to reduce the echo generated during network calls, because the network speed was relatively poor in the early years.When making an Internet call, many times there will be an "echo" in which one's own voice comes out of the headset after half a second.And this echo is also a kind of noise to some extent!So this nms company started from the echo cancellation equipment in the multi-party conference system that relied on the network that they developed at the earliest, and gradually developed equipment that can also reduce noise!But their solution is completely different from Jia Hongjian's solution!And such a product of nms company is said to have been officially launched in the United States in 97!Now that the new products launched by others have arrived, when their system is faced with two speakers, one speaker plays various background noises, and the other speaker plays people's voices, the system automatically picks up human voices!That is, the final sound transmitted by this system is the human voice after great noise reduction!It almost feels like artificial intelligence!

At the same time, Motorola in the United States also launched their "Nico technology" in the 90s.To put it simply, this NICAM technology has a built-in storage chip and a processing chip, and roughly stores the noise and voiceprint models of some typical scenes in the chip. When there is similar noise in the background of the human voice during a call, then It will be eliminated!This thing is quite awesome, but unfortunately, due to the development of the times, the storage capacity is still not enough, and because the external noise cannot remain unchanged, sometimes the composition of the noise is slightly changed, and the Liyin technology cannot be used as a result. up!After such a search, we know that companies in the United States are actually doing everything possible to develop various noise reduction technologies!But relatively speaking, the method proposed by Huaxia Hi-Tech Jia Hongjian is the simplest!

So soon, Huaxia Hi-Tech began to prepare to apply for a patent.But if you apply for a patent, you have to face another problem, that is, should the patent application be more detailed or more extensive.The so-called meticulousness means to mention all kinds of technical details—for example, after using dual microphones, if the difference between noise and human voice is found by comparison, what is the core algorithm of such a distinguishing software, and then how to reduce noise, Whether to perform vocal compensation... Anyway, it is to write out such a set of detailed things.It is relatively extensive, that is, for example, "on the basis of the traditional single-microphone pickup, add one or more microphone arrays, cooperate with the corresponding software to distinguish the difference between noise and human voice, and perform noise reduction... ..."

As for the detailed application method above, it must be easy!Because the more detailed it is, the less likely it is to rub off on other people's patents, and the easier it will be for sure!But at the same time, it is easy for me to pass over others, and it is easy for others to pass over such a patent in the future!For example, Jia Hongjian’s application was detailed, saying that in addition to the two microphones, some specific technology was used to make the judgment. Then they used three microphones and different specific technologies to make the judgment. Can such a patent be bypassed?That's right!In fact, that's what patents are all about!When a patent description is too detailed, it is easy to be approved and bypassed!To borrow the concept of "a white horse is not a horse", that is, if a patent such as "horse" is defined as a "white horse", then other people's "dark horses" can be bypassed!

Like this kind of more detailed patents, colleagues in Jia Hongjian's previous company had to bypass countless patents every year!Even if there are a hundred patents blocking a project, as long as the other party is a relatively detailed patent, as long as you think carefully, there is always a way to bypass it!Relatively speaking, relatively extensive patents are not easy to bypass!Such as a relatively conceptual patent, such as a game patent called "Crazy Taxi" by Sega, the patent application for such a game in the United States is described as follows - "an in-game object for executing the game, including the A moving object is moved... The word setting means that an unreachable area can be set around this movable object in the game..."

These words are simply not like the words that people can say!A game of driving a taxi has half a cent to do with the shit described above?But if such a complete patent of the entire Sega is clearly expressed in "human words", it is like this-"a driving game played in the city, with a time limit and a purposeful limit", " There will be a big arrow floating in the air, indicating the direction of the destination." "The driving area of ​​the car is surrounded by a circle of dangerous areas. The dangerous area may be surface-mapped as buildings or other things. The dangerous area cannot be driven into. The edges will pop off..." This patent sounds like it has something to do with "Crazy Taxi", but it sounds like it has something to do with all city racing games!For example, in the game of Need for Speed, didn't several generations also race in the city?Isn't it also forbidden to drive into the building?Except that there is no floating arrow to indicate the direction to drive, it is basically exactly the same as Sega's patent description!

There is also a patent like Konami in Japan - "game console, game device, control method, information storage medium, game release device, game release method. Kona fans hold (a control method for controlling game consoles, allowing players to Enjoy stepping while listening to game music, including a device that detects whether the player's foot or both feet are placed in one of the various positions on the pedal.)" What the hell is this? ddr, that is, the patent of a game such as "Dance Dance Revolution", within 20 years, others are not allowed to develop things like dancing mats or dancing stages, otherwise it will be a violation of Konami's patent!There is also koei, which is the patent of US Patent No. 6729954 held by Glory - the method of combat, which determines the attack power according to the density of the character group. Various game-provided characters exhibit uneven distribution of attack power, defense power, or other similar attributes).

What is this?In short, it is the patent of the "Wu Shuang" series!But it sounds like all one-to-many strike games would infringe koei's patents?That's right!This effect is what people want!At the same time, the most bizarre patent in the history of American game patents is still the patent applied by a company called entertainment-work in 1996: an image display terminal that can move according to the change of the action center of the viewpoint, and can complete spherical movement. Thereby providing both perspective and non-perspective viewing angles.The [-]D commands are stored in the terminal's memory and retransmitted according to the corresponding direction of movement.At the same time, the function of the telescoping mirror is also provided, so that the displayed image can be scaled as required.

Is this something that people can say?What the hell does this mean?This means a three-dimensional picture display technology!So in 2004, such a company sued almost all well-known game manufacturers in the world, because these manufacturers "infringed" the company's patents!What was the final result?The result is that the companies of these defendants finally chose to settle out of court with the patent holding company and spend money to settle the matter!
