Monster Factory

The poor recognition accuracy means that the bioelectricity fluctuation is small, which means that the two bioelectric wave contrast errors are small.

However, here, you can't just look at the percentage.

High precision, although the percentage is very large, but the data samples she collected are more abundant, can range from microvolts to millivolts, which is equivalent to two comparison schemes. It will only have a higher recognition rate than Otto Bock's sensor patch.

Ye Qing repeated several actions, and the error of each bio-wave was changed every time.

Accumulated five times, Ye Qing asked the crystal, if the program is intelligently identified, then the program can find the key, determinable hand-receiving signal from these bio-waves?

"Boss, in the five comparisons, the instrument collected four times, from 32 microvolts to 66 microvolts of synchronous bioelectric fluctuations." The crystal crystal stood in front of the waver and kept holding the pointed chin. "If a well-established bioelectrical database is established, I think it can be used as a basis for judgment by fuzzy comparison."

"But I can't guarantee that everyone will have this situation when collecting data. In addition, the number of sample collections is too small. I think there are at least tens of thousands of data comparisons to be more certain."

“It’s not difficult to collect, there are many people in the company.”

It seems that there is no progress, in fact, Ye Qing feels that progress has been great. As long as the signal of the palm of the hand can be accurately judged, it is equal to one on the basis of one. Because all non-1 signals can be classified as 2.

"Let's test the wave of bioelectrical signals."

Ye Qing, who calmed down, began to wave the left and right hands simultaneously.

This action has been repeated ten times.

By contrast, Ye Qing was surprised to find that in the ten actions, even 10 times were collected, which can be used to determine the same bioelectric fluctuations for personal use.

After the analysis, Ye Qing and Jing Jing agreed that this judgment comes from the bioelectrical signal released when the wrist swings.

And it is the muscle bioelectrical signal released by the wrist muscles during exercise. Because it only works in the microvolt range and is highly consistent.

"There is a head." After watching the comparison chart, Jingjing looked at Ye Qing.

"There is indeed a head start." Ye Qing nodded, an "unbelievable" incredulous expression.

The signal released by the palm of the nerve is 1 and the signal of the non-action is 2.

The wrist or arm muscles can be listed as 3 when doing certain movements.

Muscles in motion can of course produce bioelectrical activity, which is only much smaller than the bioelectrical signals released by the nerves. Otto Bock's sensor patch can't be recognized, and this kind of electro-crystal manufacturing is perfect.

1, 2, 3, it was so easy to find the idea?

"Boss, is this all too simple? You don't say Otto Bock, the technology in this area is the industry's first, I think this is the first, the water is a mess."

"I feel so too……"

Ye Qing thought for a moment and said: "In the final analysis, it should be the gap of industrial technology capabilities. Perhaps they do not have the ability to identify the accuracy of the sensor patch and improve the accuracy of one level. To detect microvolts of biological voltage changes, they can do it, but The device will be cumbersome and may be the same as the ECG recorder in the hospital."

“After detecting these subtle changes, it is a problem to apply this change to mechanical motion.”

"This difficulty is higher than the sensor patch. Without our bionic hand movement technology, even the best sensor chip is no good."

"The last is the difficulty of programming."

"How to program these signals with a simple and effective control command is also a problem."

The electric crystal patted the chest and said that everything was handed over to it.

easy to understand?

This is easy to handle, and Jingjing can build a special control program for bionic hands. Then enable the super server cluster of the company and the factory, let the program with certain intelligence, split all the actions of the human hand, each action simulates tens of billions of times, and find the simplest set of commands.

Bioelectrical sample collection?

On the night of the factory, mass production of high-precision sensor patches began. On the afternoon of the next day, 500 sets of bioelectric collection devices were sent to the company.

Each employee of the company took two hours a day, sat down on the chair and put a patch on the arm. According to the video, he made a fixed two-handed action.

Or shake hands, or applaud, or pick up a cup, or sing a sigh, scorn gesture.

These data sources are continuously collected into the super service cluster, and everyone, every gesture, will be compared and compared.

The data collection work is not always smooth, and there are many unexpected problems in the middle.

For example, the server compares the abnormal data and submits it to the technician review. Through watching the surveillance video, Jingjing found that the employee was holding a mobile phone to read the message while recording the data.

Through repeated tests, the electric crystal found that when the mobile phone is close to the inductive patch, the electronic components working in the mobile phone will release electromagnetic interference, which seriously affects the recognition accuracy of the patch.

Inductive patches have been anti-interference processing in the packaging process on the production line, and now it seems that they are still not enough.

Electro-Crystal quickly gave a solution, and these sensor patches are exposed when data is currently being collected. Put it on the product, it is actually installed in the bionic hand, the connection with the user's residual limb. As long as the electromagnetic shielding compartment is added outside the bionic hand, this problem can be solved perfectly.

There are exceptions for data overflow, and there are also exceptions for data that are greatly weak.

The survey found that the data came from a young female employee who wiped her body lotion and sunscreen cream on her arm.

Titanium dioxide and zinc oxide in sunscreen creams severely block the transmission of bioelectrical signals.

Electro-Crystal allows the product department to add a note to the instruction manual before cleaning. Please clean the joints of the limbs and do not apply cosmetics.

Some people have neither played mobile phones nor rubbed cosmetics, but the data has been abnormal.

The electric crystal turned over and over and did not find out the cause of the problem. Later, the staff of the cleaning department thought of the syndrome. She said she had mild epilepsy. She did EEG electromyography in the hospital last year. The doctor said that her nerve discharge was abnormal.

There are many similar problems.

But every time, the crystal can always give a solution quickly.

In addition, the hardware changes in the second generation of bionic hands are also very large.

In the second generation of bionic hands, Dianjing added a processor system similar to the Magic Crystal mobile phone.

The user can customize the operation command by connecting to the mobile phone. You can also upgrade your Bionics system anytime, anywhere via your mobile phone.

The connection to the stump is also doubled, so that the bionic hand is more securely connected to the user.

Dianjing also collects the nerve signals that the employees return when they touch various objects. It tries to pass these signals back to the end of the user's residual limb through another nerve of the bionic hand, allowing the user to experience the touch of the real palm.

At present, this system is still not perfect, can only simulate 30% of the touch, more like the feeling of hemp.

However, Dianjing feels that he can give the user a collection chip, let him stick it to other parts of his body, collect the tactile signals, and then tailor it to make each person's exclusive touch.

In the midst of busyness, there was news from Mead Hospital, and they had a plan for the propaganda timing of the bionic hands.
