Monster Factory - 1066

Poor recognition accuracy means that the bioelectricity fluctuation range is small, and it also means that the comparison error of the two bioelectric waves is small.

But here, we can’t just look at it in terms of percentage.

High precision, although the percentage is large, the data samples it collects are more abundant. Being able to go from microvolts to millivolts means that there are two comparison schemes.

It will only have a higher recognition rate than Ottobock’s sensor patch.

Ye Qing repeated the action several times, and the error of the bio-waves changed every time.

Five times in total, Ye Qing asked Dianjing, if the program is allowed to recognize it intelligently, can the program find the key and determinable hand-retraction signals from these bio-waves?

“Boss, in these five comparisons, the instrument has collected four times, from 32 microvolts to 66 microvolts of synchronized bioelectrical fluctuations.” The electric crystal stood in front of the wave display and kept pinching the pointed chin. “If a complete bioelectricity database is established, through fuzzy comparison, I think it can be used as a basis for judgment.”

“But I can’t guarantee that this will happen to everyone when collecting data. In addition, the number of sample collections is too small. I think at least tens of thousands of data comparisons can be more certain.”

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

It seems that there is no progress, but Ye Qing feels that there is a lot of progress. As long as the signal of the palm of the hand can be accurately judged, it is equal to the addition of a 2 on the basis of 1. Because all signals other than 1 can be classified into 2.

“Let’s test the wave of bioelectric signals again.”

Ye Qing calmed down and began to wave his left and right hands simultaneously.

This action has been repeated ten times.

By comparison, Ye Qing was surprised to find that out of these ten actions, ten of them were collected, which can be used to determine the same bioelectric fluctuation segment for personal use.

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

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

“Something to do.” After reading the comparison chart, Dian Jing looked at Ye Qing again.

“It’s really something.” Ye Qing nodded, with an expression of disbelief “Is it that simple?”

The palm contraction signal released by the nerve is 1, and the nerve signal that is not this action is 2.

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

Muscles can also produce bioelectrical activity during exercise, but it is much smaller than the bioelectrical signals released by nerves. The sensor patch of Ottobock can’t recognize it, but the one made by Dianjing is completely ok.

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

“Boss, all this is too simple? Don’t you say that Ottobock is the industry’s first technology in this area. I think it’s the first one, and it’s a mess.”

“I feel so too……”

Ye Qing thought for a moment, and said: “In the final analysis, it should be the gap in industrial technology capabilities. Perhaps they have not improved the recognition accuracy of the sensor patch by an order of magnitude. They can detect microvolt-level biological voltage changes, but they can do it, but That set of equipment will be bulky and may be the same as the ECG recorder in the hospital.”

“In addition, after detecting these subtle changes, whether this change can be applied to mechanical motion is another question.”

“This is more difficult than the induction patch. Without our bionic hand movement technology, no matter how good the induction patch is, it is useless.”

“Finally is the difficulty of programming.”

“How to program these signals into a set of simple and effective control commands is also a problem.”

Dianjing patted his chest and said that he would leave everything to it.

easy to understand?

This is easy to handle, and Dianjing can build a special control program for the bionic hand. Then use the super server clusters of the company and the factory, let a program with a certain intelligence, separate all the actions of the human hands, simulate each action tens of billions of times, and find the most concise set of commands.

Sample collection of bioelectricity?

The factory started mass production of high-precision sensor patches that night, and by the afternoon of the next day, 500 sets of bioelectric collection devices were delivered to the company.

Each employee of the company takes out two hours a day, sits on a chair, puts stickers on his arms, and makes fixed hand movements based on the video over and over again.

Either shaking hands, or applauding, or holding up a tea cup, or making gestures of admiration and contempt.

These data sources are continuously collected in the super service cluster, and every person and every gesture will be centrally compared.

Data collection has not been smooth sailing, and there have been many unexpected problems.

For example, when the server compares abnormal data and submits it to DianJing for review. Dianjing looked through the surveillance video and found that this employee was holding a mobile phone in one hand to read the news during the data recording process.

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

In the packaging process of the induction patch on the production line, anti-interference treatment has been done, and now it seems that it is far from enough.

Dianjing quickly provided a solution. At present, these sensor patches are exposed to the outside during data collection. Put it on the product, it is actually installed at the connection between the bionic hand and the user’s stump. As long as an electromagnetic shielding barrier is added to the outside of the bionic hand, this problem can be solved perfectly.

There are anomalies where data overflows, and there are also anomalies where data is significantly weakened.

After investigation, it was found that this data came from a young female employee who wiped body lotion and sunscreen on her arm.

Titanium dioxide and zinc oxide in sunscreen cream severely block the transmission of bioelectric signals.

Dianjing asked the product department to add a note to the instruction manual. Before use, please clean the joints of the limbs and do not apply cosmetics.

There are also people who neither play with their phones nor wipe cosmetics, but the data is always abnormal.

Dianjing tossed and did not find out the cause of the problem, hell.

Later, it was the employee of the cleaning department, and he thought of the problem. She said that she had mild epilepsy. She had an EEG electromyogram in the hospital last year, and the doctor said that her nerve discharge was abnormal.

There are many similar problems.

But every time, Dianjing can always give a solution quickly.

In addition, the hardware changes in the hands of the second-generation bionics are also great.

Dianjing has added a processor system similar to the magic crystal mobile phone inside the second-generation bionic hand.

Users can connect via mobile phones to customize and modify operation commands. It can also upgrade the system of the bionic hand anytime and anywhere through the mobile phone.

The connection with the residual limb has also been doubled, so that the connection between the bionic hand and the user is stronger.

The transistor also collects the nerve signals that the employees’ palms give back when they touch various objects. It tries to feed these signals back to the end of the user’s stump through another nerve feedback patch of the bionic hand, so that the user can experience the touch brought by the real palm.

At present, this system is not perfect. The bioelectricity it releases can only simulate 30% of the touch, which is more like a hemp feeling.

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

In the midst of their busy schedule, news came from Mead Hospital, and they had plans for the propaganda timing of the bionic hand.
