Simulation Robot Laboratory, Guizhou University of Technology.

This laboratory is very large, with tables filled with various scientific instruments. On the table in the middle, there is a half-human-tall female simulation robot that has not been completed.

"Oh, be careful! Don't break it!" Rajesh shouted with concern on a test bench in the corner of the laboratory.

"Don't worry! I'm a master of engineering! Dismantling machines is my strength!" Howard, who was carrying goggles next to him, held various tools in his hand, raised his hand.

"Oh, master's degree!" Sheldon over there laughed with a crooked mouth.

Fortunately, Howard had long been used to his prejudice against low-education people, so he did not get angry, so he buried his head again and started working.

On the table in front of him was a beautiful dream helmet with a white plastic shell. The tools in his hand were reaching into the gap of the helmet and pulling them hard.

"Click"

With a crisp sound, the snaps between the plastic loosened, and the gap at the edge of the helmet expanded a little further.

His subordinates kept moving the tools.

"Click", "Click", "Click", "Click"

The nine fixing casing snaps were opened one by one, and the milky plastic shell and the soft lining were separated.

"Oh! Hurry, hurry, hurry!" Sheldon over there looked anxious: "Let's see what's inside!"

Howard didn't say anything, reached out and took off the shell, revealing the dense electronic components inside.

"Wow, this is so beautiful!" Leonard on the other side praised.

"What are these parts for?" Rajesh next to him asked in confusion.

"Oh, I'm just a master's degree in engineering and I'm not stupid in electronics. How could I know?" Howard looked helpless: "Don't you know how to search the Internet?"

The other three people picked up their phones and searched.

Howard continued to work, twisted the screws, and removed the circuit boards and parts inside one by one.

"Oh, I found it! This thing should be an unlimited charging module!" Sheldon over there called out first: "There are sold on Yassun, exactly the same as this one, only .5 meters!"

"If this circuit is connected to the display screen, it should be a display module." Leonard on the other side analyzed.

"Also, this is a lithium battery, only 200 mAh." Rajesh also pointed to a part.

"These are several ball fans, brushless motors, and liquid-cooled heat conductor pipes!" Sheldon continued: "I said why did I wear this helmet so cool? It turns out that there are these things inside!"

"No, why is this fingerprint recognition module not connected to the LCD display module?" Leonard stretched out a hand and pointed at one of the components, expressing his question: "This fingerprint recognition module is only connected to the battery, so how does it transmit the read results?"

Others looked over, and Howard also saw something was wrong: "Indeed, the helmet was bound to our fingerprints, but the recognizer did not transmit the recognition signal. So how did it identify that we belong to me?"

"Wait! Leonard, take out your helmet too!" Sheldon called, "Let's compare!"

"Okay." Leonard shrugged and picked up the helmet in his backpack.

"Click it." Howard ordered.

Leonard stretched out his index finger with his right hand and tapped on the fingerprint button of his helmet, and the five-pointed star display turned red.

"Click it again!" Howard ordered again, and the others also stared at him.

Once again, the screen turned blue.

"Come on again!"

Another thing is that the screen is dark and turns black.

"Let me do it!" Rajesh walked over, took the helmet, and also tapped it with his right index finger.

The helmet did not respond at all, and the five-pointed star's display was still dark.

Sheldon and Howard also tried it, and the results were the same.

Leonard took back his helmet and tried again. Only then did the helmet react. There was no doubt that the fingerprint reader only recognized his fingerprint.

"There is no reason for this." Howard frowned: "This fingerprint reader only connects the battery and does not connect other components. Even if it saves the fingerprint and recognizes the fingerprint, how can it send the recognition signal out and make the light light light up?"

The other three were also highly educated science and engineering men, and immediately discovered the problem.

"Did you break it? Cut off the wire connected to my helmet?" Rajsh looked sad and angry.

"Where is it? When I opened it, you will be there, where is the connection cable?" Howard cried out: "Everything is here, where is it?"

"Wait! I have a way!" Sheldon shouted: "I remember when I came last time, you had a latex or something, which could copy fingerprints, right? Last time we tested the fingerprint system of a fruit phone, didn't we use those copied fingerprints to easily turn on other people's phones?"

"Oh, yes! Let's try again!" Howard slapped his head, walked to another table, and brought a scanner and a ball of pink colloid.

"Leonard." Howard called out.

Leonard reached out and put it on the scanner. The red light swept across and his fingerprint appeared on the computer screen.

Then put the colloid into a machine. Soon, a hand made of pink colloid pointed it out in the machine.

The finger was taken out, and it was clear on it, with Leonard's right index finger fingerprint.

"Try it again!" Howard took Leonard's helmet and pressed the fake finger on the button.

As before, there was no response.

"This shouldn't be." Raje on the other side started to scream.

"Leonard, your phone!" Sheldon responded quickly.

Leonard took out his fruit cell phone.

The fake finger was placed on the fingerprint button on the back of the phone.

In an instant, the screen lights up, unlocks instantly, and enters the main interface.

"Why is the fruit mobile phone possible, but the Haomeng helmet not?" Leonard took back his phone and expressed his confusion: "Is this Chinese company's fingerprint recognition technology better than our fruit company?"

"Identification technology is not the key point, the key is how it transmits the recognition signal!" Howard frowned and fell into deep thought.

Leonard thought for a while, then picked up his helmet and the fake finger on the table.

He pressed his fake finger back on the fingerprint recognition button.

In an instant, the screen lit up!

"What's going on?" His face was full of surprise.

After pressing it again, the red star turned into a blue star. When pressing it again, the screen became darker.

"I'll do it!" Howard took his helmet and his fake finger again.

Press once, there is no response, and press again, there is no response either.

Others have tried it one by one, except Leonard, and others use fake fingers and helmets to respond.
