In other words, it is equivalent to having an "automatic" hand to play, and because the number of paper roll punches is not limited by the number of fingers of the hand, the number of notes and the range on the piano can be used as much as possible, so the player piano is still favored by modern composers. Pen & Fun & Pavilion www.biquge.info

Famous Rachmaninoff, Debussy, Mahler, Gershwin, and R. Strauss have all written music for this instrument, which was made into paper tape for performance.

The player piano was the most popular in 20 years, with a record of 500,000 units produced in two years. Of course, it can only be used by upper-class families.

Now, this player piano has given Ciric a big hint.

What's the tip? Of course, it is about the development of electronic communication technology!

Now, all kinds of German weapons are improving, such as all kinds of missiles, which are the simplest radio command guidance, this kind of thing, it is very easy to be jammed!

There are also a large number of radios, radars equipped with the German army, which are easily jammed!

How to improve the anti-interference ability? In later generations, this is already a consensus!

Frequency hopping.

For example, in terms of communications, the old-fashioned radio stations are quite backward and have no anti-jamming ability, and the advanced army is equipped with frequency-hopping radios, which constantly change the frequency according to the prior procedure so that the other party cannot interfere.

And this technology came from the player piano!

"If we use the principle of this player piano to formulate the order of frequency changes in both aspects of the communication terminal, we can greatly improve the anti-interference ability of communication..."

I am not omnipotent, it is impossible to remember everything, and I have forgotten this major invention about communication systems.

If you use this method of communication, you can make your own missiles no longer suffer from electromagnetic interference, and your own communication will not be interfered with!

"Frequency-hopping communications? It's a good idea and solves a big problem in terms of communication. At that moment, a voice chimed in.

Ciric turned his head and saw an equally excited face.

When Eva was in college, she studied communication! Although she later pursued art and gave up her major, Eva is a very smart girl, and her mathematical skills are also extremely rich!

Now, hearing Ciric's words, Eva was also quite shaken, a new window suddenly opened in front of her, and she had an impulse to engage in this kind of frequency-hopping communication technology!

Before the divorce, she often heard a lot from her husband, who, although also Jewish, was a big supporter of Hitler, and who had these problems when he spoke about torpedo correspondence.

Now, she has suddenly found a solution, although it has nothing to do with her!

Looking at the woman in front of him, Ciric suddenly asked, "Have you ever acted completely naked before?" ”

Ciric's words made Eva blush, and even Hannah on the side was unhappy, she trusted her husband, but such a question was too hurtful to people's pride.

However, Eva could only blush and nod in agreement, at that time, she was still too young, if she was given a chance to choose again, she would definitely not take that film.

Now, will it be looked down upon by General Ciric?

"Okay, that's you!" Ciric finally linked her with Heidi in history, and starred in the nude, there is no one else in this era, it is her!

"Eva, are you interested in contributing to the empire?" "If you do what I ask," said Ciric, "you will become a holy Aryan." ”

The title of Holy Aryan, which is now coveted by many, is a title that every non-Germanic wants to receive after constant propaganda in Germany.

It didn't take much effort to get it!

Historically, Heidi Lamarr and the piano composer Georges Antheil devised an airplane navigation system. George conceived a pair of paper rolls, one inside the plane and one in the torpedo, to specify the order of the frequency of change.

By 1941, they had completed this research and patented the design of their "frequency hopping" device, which became known as "spread spectrum communication technology".

This is a method of communication for guiding torpedoes, controlled by a device similar to an automatic piano musical tube, which has a unique sequence of 88 possible steps. By sending only a small part of the entire message on each frequency, the torpedo can be manipulated.

The results of their research are quite great, and it can be said that they have opened the door to a higher level of radio communication!

It was only 42 years, and they wanted to donate the patent to the U.S. government in the hope that it would help World War II.

Unfortunately, when Heidi opened the drawings, it was revealed that some parts of it functioned like the basic mechanism in an automatic piano. At the time, military officers thought it was ridiculous.

For them, Heidi herself was more attractive.

Moreover, since Heidi's first marriage was to support Hitler's Mandel, the CIA personnel wondered if Heidi was fooling the military with this thing.

As a result, this technology was not used in World War II.

Now, Ciric suddenly met Eva, the current Eva, has not changed her name to Heidi, and is not disgusted with the current German government, in this case, it is better to appoint Eva to quickly put this frequency hopping system into practice!

Hannah then realized that Ciric had something important, not a joke, and didn't care that Eva had ever acted naked. Just to confirm something.

"I'm more than willing to do anything." Eva said excitedly.

"We have perfected the frequency-hopping communication technology we just mentioned." Ciric said: "The empire will set up a special laboratory to provide you with sufficient funds and personnel, but you are also required to keep it secret, this technology will be of great help to the empire." ”

"Yes, I am willing to serve the Empire." Eva immediately agreed.

The influence was subtle, and when Germany did not massacre Jews in large numbers and used Holy Aryans to whitewash, it was easy to attract more people to serve the Reich, and these people were the most valuable treasures!

Hitler nodded: "The Reich will remember your credit." If this task is completed well, perhaps, you can also continue to develop in your acting career and bring more excellent films to the empire. ”

Eva is so beautiful, of course she can put it on the screen and perform some inspirational films to boost the morale of the army.
