Jianzhou University of Technology, Simulation Robotics Laboratory.

This laboratory is very large, with tables full of all kinds of scientific instruments, and on the middle table, there is a half-human-high, half-made, unfinished female simulation robot.

"Oh, be careful! Don't break it! On the edge of a test bench in the corner of the lab, Rajesh cried out worriedly.

"Don't worry! I'm a Master of Engineering! Dismantling machines is my forte! Next to him, Howard, who was wearing goggles and holding various tools in his hands, raised his hand.

"Oh, Master!" Sheldon over there smirked.

Fortunately, Howard had long been accustomed to his prejudice against people with low education, so he didn't get angry, buried his head again, and got to work.

On the table in front of him, there was a white plastic shell of the Good Dream helmet, and the tool in his hand was reaching into the gap between the helmet, wrenching it vigorously.

"Click"

With a crisp sound, the clasp between the plastic was loosened, and the gap between the edges of the helmet widened again.

His men kept moving.

"Click", "Click", "Click", ......

The nine clips that hold the shell in place are opened one by one, and the milky plastic shell is separated from the soft lining.

"Oh! Hurry, hurry, hurry! Sheldon over there looked urgent: "Let's see what's in there!" ”

Howard didn't speak, reaching out and removing the case, revealing the dense electronic components inside.

"Wow, this is so beautiful!" Leonard on the other side exclaimed in praise.

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

"Oh, I'm just an engineering master, and I'm not stupid in electronics, how do I know?" Howard looked helpless: "Don't you know how to search the Internet?" ”

The other three picked up their phones one after another and searched for them.

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

"Oh, I found it! This thing is supposed to be an infinite charging module! Sheldon over there first shouted: "Yayangxun is sold above, exactly the same as this one, only 16.5 meters!" ”

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

"Also, it's a lithium battery, and it's only 2,800 milliamps." Rajesh also pointed to a part.

"It's a couple of ball fans, brushless motors, and liquid-cooled heat pipes!" Sheldon continued, "I said how to wear this helmet so cool, it turns out that there are these things in it!" ”

"No, why is this fingerprint recognition module not connected to the LCD module?" Leonard stretched out a hand and pointed to one of the parts, questioning: "This fingerprint recognition module is only connected to the battery, so how does it transmit the reading results?" ”

The others looked over, and Howard also saw that something was wrong: "Indeed, the helmet is bound to our fingerprints, but the recognizer does not transmit an identification signal, so how does it recognize that we are the person?" ”

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

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

"You click." Howard commanded.

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

"One more click!" Howard commanded again, and the others stared at each other.

One more time, the screen turns blue.

"One more time!"

Again, the screen was darkened and turned black.

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

The helmet didn't react, and the pentagram's display was still dim.

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

Leonard retrieved the helmet and tried it again, and the helmet reacted, and there was no doubt that the fingerprint reader only recognized his fingerprints.

"There's no reason for that...... Howard frowned: "This fingerprint reader is only connected to the battery, and no other parts are connected, even if it saves fingerprints and recognizes fingerprints, how does it transmit the identification signal and make the lights on?" ”

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

"Did you break it? Cut off the cord attached to my helmet? Rajesh's face was filled with grief and indignation.

"Where? When I dismantle it, you just look at it, where is the connecting line? Howard exclaimed, "Everything is here, where is it?" ”

"Wait! I've got a way! Sheldon exclaimed, "I remember the last time I came, you had a kind of latex or something here, you can copy fingerprints, don't you?" The last time we tested the fingerprint system of the fruit phone, didn't we use those copied fingerprints to easily open other people's phones? ”

"Oh, yes! Let's try again! Howard patted his head and walked over to another table, bringing a scanner and a cloud of pink gel.

"Leonard." Howard shouted.

Leonard reached out and placed it on the scanner, a red light swept through, and his fingerprints appeared on the computer screen.

The gel was then put into a machine, and after a while, a finger made of pink gel appeared in the machine.

The finger was taken out, and it was clear above it, the fingerprint of Leonard's right index finger.

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

As before, there was still no response.

"It shouldn't be......" Rajesh cried over there.

"Leonard, your phone!" Sheldon reacted quickly.

Leonard pulled out his fruit phone.

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

In an instant, the screen lit up, unlocked in an instant, and entered the main interface.

"Why is the fruit phone okay, but the good dream helmet can't?" Leonard took back his mobile phone and expressed puzzlement: "Could it be that the fingerprint recognition technology of this Huaguo company is better than that of our fruit company?" ”

"The identification technology is not the key point, the key is how it transmits the identification signal!" Howard's brow furrowed, lost in thought.

Leonard thought for a moment, then picked up his helmet on the table, along with the fake finger.

He pressed the fake finger back on the fingerprint button.

In an instant, the screen lit up!

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

Press it again, and the red star turns into a blue star, and when you press it again, the screen goes dark.

"I'm coming!" Howard regained the helmet and the prosthetic fingers.

Press it once, there is no response, press it again, there is no response as well.

Others tried it one by one, except for Leonard, everyone else used fake fingers, and the helmet didn't respond.

"There's definitely something wrong with this helmet!" Sheldon was the first to cry. 2k reading web
