In other words, it is equivalent to having an "automatic" hand to play. Moreover, because the number of holes in the paper roll is not limited by the ten fingers of the human hand, the number and range of the piano can be used as much as possible, so automatic pianos are still favored by modern composers.

The famous Rachmaninov, Debussy, Mahler, Gershwin, and R Strauss have all written music for this instrument and made paper tapes for performance.

Automatic pianos are the most popular in 20 years, with a record of producing 500,000 units in two years. Of course, they can only be used by high-ranking families.

Now, this automatic piano gives Cialek a big hint.

What tips? Of course, it is about the development of electronic communication technology!

Now, all kinds of weapons in Germany are improving, such as various missiles, which are the simplest radio command guidance, and this kind of thing is easily disturbed!

There are also a large number of radio stations and radars equipped by the German army, which are easily disturbed!

How to improve anti-interference ability? This is a consensus in later generations!

Frequency hopping.

For example, in terms of communication, old-fashioned radio stations are quite backward and have no anti-interference ability. Advanced troops are equipped with frequency hopping radio stations. According to prior procedures, the frequency is constantly changed so that the other party cannot interfere.

And this technology comes from the automatic piano!

"If we use this principle of automatic piano and formulate the order of frequency changes in both aspects of the communication terminal, we can greatly improve the anti-interference ability of communication..." Cialek keenly grasped something and murmured to himself.

I am not omnipotent, and I cannot remember everything, but I have forgotten this major invention about the communication system now.

If you use this method to communicate, your missiles will no longer be affected by electromagnetic interference, and your communications will not be affected by interference!

"Frequency hopping communication? This idea is very good, and it just solves a big problem in communication." At this moment, a voice next to his ear echoed.

Cialick turned his head and saw an equally excited face.

When Ava was in college, she studied communication! Although she later pursued art and gave up her major, Ava was a very smart girl, and her math skills were extremely rich!

Now, after hearing Cialik's words, Eva was also quite shocked. A new window suddenly opened in front of her. She had an impulse to engage in this kind of frequency hopping communication technology!

Before divorce, she often heard her husband say a lot. Although her husband was also a Jew, he was a person who was very supportive of Hitler. His husband encountered these problems when he talked about torpedo communication.

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

Looking at the woman in front of him, Cialick suddenly asked, "Have you ever played naked before?"

Cialick's words made Eva blush, and even Hannah was unhappy. She trusted her husband, but such questions were too hurtful.

However, Eva could only blush and nodded in agreement. At that time, she was still too young. If she was given a chance to make a new choice, she would never take on that movie.

Now, will General Cialek be looked down upon?

"Okay, that's you!" Cialick finally linked her to Heidi in history. She starred in naked form. There is no one else in this era, she is just her!

"Ava, are you interested in contributing to the empire?" said Cirick. "If you follow my request, you will become a Sacred Aryan."

The title of the Sacred Aryan is now something that many people dream of. After continuous publicity in Germany, every non-Germanic person hopes to obtain this title.

It takes no effort to get it!

Historically, Heidi Rama and piano composer George Antyre designed an aircraft navigation system. George conceived a pair of paper rolls and placed them in the aircraft and torpedoes to specify the order of the frequency of change.

By 1941, they completed this research and applied for a patent for their "frequency jump" device design. This "frequency jump technology" is the "spread spectrum communication technology" of later generations.

This is a communication method that guides torpedoes, controlled by a device similar to an automatic piano music cylinder, which has a unique sequence of 88 possible steps. By sending only a small portion of the entire message on each frequency, the torpedoes can be manipulated.

Their research results are quite great, and can be said to have opened a higher level of door to radio communication!

This is only 42 years. They originally wanted to donate this patent to the US government, hoping it would be helpful to World War II.

Unfortunately, when Heidi opened the drawings, it showed that some parts of it worked like basic mechanical devices in an automatic piano. But at that time, military officers thought this was ridiculous.

To them, Heidi herself is more attractive.

Moreover, since Heidi's first marriage was with Mandel, who supported Hitler, the CIA staff made him wonder if Heidi was using this thing to fool the military.

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

Now, Cialek suddenly met Eva. The current Eva has not changed its name to Heidi. Moreover, he is not disgusted with the current German government. Since this is the case, it is better to appoint Eva to quickly make this frequency hopping system practical!

Only then did Hanna realize that there was something important about Cialis, not a joke, nor did she care about Eva's role in nakedness. She just wanted to prove what she wanted.

"I'm very willing to do anything," Eva said excitedly.

"Improve the frequency hopping communication technology we just mentioned." Cialek said: "The Empire will set up a special laboratory to provide you with sufficient funds and personnel, but it also requires you to keep it confidential. This technology will be of great help to the Empire."

"Yes, I'm willing to serve the empire." Eva agreed immediately.

The influence is subtle. When Germany did not massacre Jews and used the Sacred Aryans to cleanse them, it was easy to win over more people to serve the empire. These people are the most precious wealth!

Hitler nodded: "The Empire will remember your contribution. If this task is completed well, perhaps, you can continue to develop in your acting career and bring more excellent films to the Empire."
Chapter completed!
