Chapter 240 Angel Investment

The next day, Professor Mojia and Harvey came back to the radio room of the Radio Association. At this time, the content on the blackboard had been completely wiped out.

But it doesn't matter, because they have recorded all the previous content.

The reason why they came here is to ask the members of the association if they know who wrote the numbers on the blackboard.

But when asked, everyone shook their heads one after another.

Some people have not seen these numbers at all, and those who have seen them are not clear.

Wu Fei, the only insider, did not come over because his girlfriend had twisted her ankle and wanted to take care of her, so Professor Murray did not know any useful clues.

The most troublesome thing is that the MLT Radio Association just welcomed two groups of people who came to visit two days ago. Those members came from a complicated way, including other universities and ham friends who have already worked in the society.

Therefore, it is not necessarily someone in MLT, but also someone outside the school. After Professor Murray asked a few people, he didn't get any useful information. "Who is it?"

Professor Murray really can't figure it out.

He basically went through the people on the campus, and some possible people were excluded by him.

So, there is only one possibility left. The other party is an off-campus personnel.

After Professor Murray asked several times, although he regretted it, he no longer had any hope.

However, Harvey did not give up, but picked up the chalk and wrote a short briefing on the blackboard.

The content is very simple, that is, a reward is offered to find the person who wrote the previous numbers on the blackboard a few days ago. If anyone knows who it is, you are also welcome to call his mobile phone directly. Moreover, in order to avoid misunderstanding, he was only interested in the algorithm.

Harvey did not say exactly what the reward was, because he was a little famous in the Radio Association. After all, he was a proud disciple of Professor Murray. As long as he was an old man of the Radio Association, he had more or less heard his name from Professor Murray.

In fact, Lin Hong does not know the spread spectrum alarm technology. The radio code he mastered is only narrowband communication.

Therefore, when the calculation was staged on the blackboard, he did not have a clear purpose at all, but intuitively felt that this method could restore the information of the sale.

After returning home, he immediately recalculated the contents on the blackboard.

Moreover, this time, instead of using manual calculation, he used a computer to enter all the data into a file, then wrote a small program to read the data in the file according to a specific algorithm, and then automatically calculated according to the algorithm he set, and finally obtained a completely different code sequence. Column.

Through the final obtained piece sequence, Lin Hong deduced the reverse, and finally pushed the decoding sequence backwards.

According to the original sequence of chips, as long as you use this decoding sequence, and then perform matrix transformations such as multiplying or adding and subtracting according to the specified method, you can get the final real data smoothly.

Although he has very little information in his hand, and this decoding sequence is not necessarily 100% correct, he knows that there is nothing wrong with his method. As long as he has more measurement data, it is only a matter of time to obtain an accurate decoding sequence.

However, after this point, he can't continue.

He doesn't know what the code sequence he got means.

It is not even clear why this code can be obtained through such a transformation.

The situation he encountered was completely "knowing it but not knowing why..." He got the key, which was completely caused by his ** and intuition about the data, but he was not sure why he could get the key in this way.

He just had such a vague impression in his mind. He regarded this process as a kind of encryption and decryption in radio coding. As for why he did so, it was not very clear. In fact, he also felt strange that there was only a little information. Why did it make it so complicated? Is it just for encryption?

This semester is almost over, the school has fewer and fewer courses, and some elective courses have entered the examination stage.

The exams here are also very characteristic. Basically, there are few closed-book exams, especially elective courses. The teacher usually assigns you a topic and then asks you to write it as a thesis.

As for how to write, it depends on your own performance. You can go to the library or consult some professionals.

Although Lin Hong doesn't value grades very much, he still completes these topics seriously, because he can learn a lot in the whole process of completing the paper. He also saw that the final paper is not the purpose, but the key lies in the process, which lies in the students' ability to investigate and solve problems.

Although Texas Instruments' acquisition of SAM has not been successful, the recent development of SAM has been good.

Now SAM has added three new members, all of whom are externally hired technicians, including software and hardware.

Recently, SAM has not stopped developing products.

CDAD devices have been launched in several versions.

The previous version was designed for broadcasting and synchronization in public places, so many infrared transceivers were used in the design, and the angle also took care of all directions.

Later, SAM found that many users actually installed CDAD in their own bedrooms, and some people even installed it just to facilitate their contact with their families, because compared with expensive mobile phones and phone bills, calculators are obviously very economical.

Especially the SMS function. During this period, there is no such function on the mobile phone. The SMS function in the calculator is a very big innovation. Therefore, this software was welcomed by everyone as soon as it was released.

This software is also the most popular software companion of all calculator software.

Nowadays, the common way for students to contact other friends is no longer through letters or phone calls, but directly using the calculator in their hands. Even in class, everyone secretly uses this text message.

Therefore, in order to meet this requirement, SAM has specially launched a home version of CDAD devices. In this version, the display and buttons are directly integrated, and it is no longer just a synchronization device. At the same time, it has the function of a calculator, which is more powerful than the modified calculator, and even comparable in some aspects. The computer is beautiful.

And SAM also fulfilled Matthew's previous promise to the principal and took the lead in developing a lot of software specially developed for school life. For example, the teacher doesn't even have to rewrite the homework or topic on the blackboard. Just take out your calculator and upload it to the CDAD server, and the students can download it directly.

If there is any important notice in the school, it can also be sent to the calculator in the hands of each student at the first time, which has been greatly improved. The efficiency of information transmission is in accordance with Matthew's concept. It is best to integrate the functions of computer networking into the CDAD device, so that as long as it is directly with the modem When connected, you can surf the Internet without buying another computer to synchronize.

Of course, this function has not been realized for the time being, but only as the future development direction.

Texas Instruments talked with SAM several times, and eventually the acquisition was finally possible because their conditions were too harsh.

However, the recent development of SAM has attracted the attention of some angel investors.

Angel investment is also a form of venture capital. Angel investors usually refer to investors who invest in very young small and medium-sized enterprises or teams that have just started their own businesses.

For entrepreneurs, they may only have good creative ideas and technologies, but lack enough start-up capital. At this time, if one can invest in them, they may be able to fly to the sky and create miracles. This person or institution, in the eyes of entrepreneurs, is like an "angel", which is of great help to entrepreneurs, so he is affectionately called an angel investor by them.

Angel investors can be individuals or institutions. They are usually the first investors of small and medium-sized enterprises. The amount of investment can be large or small, or even tens of thousands of dollars, which is very different from those venture capitals that often cost millions or even hundreds of millions of dollars.

These days, there have been several angel investors Xiang Niu one after another. The company expressed its interest in investment.

Compared with selling the whole company directly, people are more inclined to absorb investment, continue to make SAM bigger and stronger, and provide better services and products. Therefore, everyone does not exclude angel investment.

Although SAM is already profitable, the profit is not very large in a month. It is okay to develop steadily. However, considering that the speed of change in the electronics industry is very fast, if it has been satisfied with the status quo, it is likely to be replaced by other companies and eliminated by the market.

This is not alarmist, because now similar companies have begun to appear in the market, especially when some people know that after the Infrared Data Association is about to release the infrared standard communication agreement, many companies have begun to prepare for similar businesses, and even Texas Instruments has set up relevant departments and research and development. Similar products that look like CDAD devices.

Everyone seems to be sure that wireless communication will be a huge cake in the future, and infrared communication is the first relatively mature solution.

Previously, major manufacturers were fighting separately and developing independently. Not only was the transmission rate and efficiency very low, but also the technical parameters in all aspects were not unified, and no common standard was formed, resulting in the inability of communication between platforms.

Now, with the leadership of the Infrared Data Association to formulate a unified standard, and then everyone joins it, it can greatly promote the development of infrared data transmission technology.

However, few people know that the core technology of the Infrared Data Association was purchased from a teenager.

It passed quietly, and from tomorrow on, the school will start the summer vacation.

Before school, Lin Hong received a text message from the company's debt.

"Let's go together after school."
