Chapter 894: New Technology

Sunlight shines through the south window onto the pink puzzle carpet laid out in the room, casting a large bright diamond-shaped patch of light.

Squatting on the light spot, Atletico Madrid posed with his hands in various poses, transforming the shadows into various animal shapes, and at the same time telling animal stories in his mouth, mixed with various imitation ventriloquism, which attracted the screams of the young audience next to him.

The E7U allows him to manage his striated muscles all over his body, and he can do gestures and learn ventriloquism. Zhizhi and the others couldn't do it, they tried to imitate it many times, but they were always clumsy and couldn't learn the idea, so they had to pester their father to let him perform for everyone to see.

"Then, the eaglet spread its wings and flew away," stood up and let the hand shadow eaglet fly out of the "light curtain", Atletico spread his hands, "Okay, that's all for today, your dad and I want to rest for a while, don't come to disturb me!"

Saying this, he sat down on the spot, folded his legs, and put on a meditation posture with five hearts facing the sky, and instantly entered a meditative state of ignoring external objects.

Of course, this is a false concentration, although the eyes are tightly motionless, the exchange of information between the body and the environment is not interrupted, and the surrounding wind and grass are still under control.

At first, the four snacks didn't know this, but they thought it was funny to see their father sitting like this, and they couldn't help but want to come over and pinch their nose and pinch their ears, but it was their own little nose and ears that were pinched. After a few times, they finally remembered that when they saw Atletico sitting like this, they consciously dodged and couldn't bother, anyway, it wasn't that there was nothing else to play with, and soon the room was filled with the noise of chickens fighting on horsebacks.

On the other hand, Atletico sank consciousness into their minds and continued their research.

He is also the director of the Bee Research Institute and is constantly publishing new results, most recently in the application of WiGig network technology.

WiGig (wireless gigabit) is an ultra-high-speed wireless LAN communication protocol jointly initiated by Intel, Microsoft, Broadcom and other enterprises, which is specially developed for transmitting high-definition video streams, also known as IEEE (Institute of Electrical and Electronics Engineers) 802.11ad.

The new protocol works in the 60Ghz frequency band, avoiding the 2.4/5GHz public frequency band where a large number of wireless devices gather, and WiGig devices can occupy a large number of open channels, so as to easily achieve wireless gigabit broadband, whether it is to watch multiple 4K live broadcasts or enjoy high-quality VR images.

Two years ago, the WiFi Alliance announced the adoption of WiGig as an alternative to 802.11ac to enable Gigabit Wi-Fi. Driven by Intel and other alliance members, various devices equipped with this technology: wireless displays that only need to be plugged in, wireless SD cards that are faster than data cables, VR displays that are clearer, and gigabit high-speed mobile phones, are gradually appearing.

Bee also attaches great importance to this technology, and the latest Dreamwalker Explorer/Pro Edition, as well as the upcoming Bee 8/C4 phone, all achieve perfect support for WiGig through self-developed baseband, which takes LAN speed to new heights.

However, there are pros and cons, and the reason why this band is empty and rarely used is because it also has obvious shortcomings.

First of all, the diffraction ability is insufficient, and it is easy to be affected by obstacles.

Acoustic waves, light waves, seismic waves, as long as the property is a wave, have diffraction characteristics, and diffraction phenomena occur when encountering obstacles, and can continue to propagate around obstacles. The diffraction phenomenon is most pronounced when the physical size of the obstacle is close to or smaller than the wavelength.

For electromagnetic waves, the lower the frequency and the greater the wavelength, the stronger the ability to bypass obstacles, the farther the signal can travel, and the less equipment investment there is, and vice versa. The three major operators are drooling over the 700MHz frequency band for radio and television, which is because of this.

This is the case for operators, and the same is true for other manufacturers, the ISM engineering and medical public frequency band contains two frequency bands, but most wireless devices have chosen 2.4GHz, just to obtain just the right ability to go around obstacles and pass through walls. It wasn't until this band was flooded and the demand for high-speed networks increased significantly that the industry began to pay attention to the 5GHz band and packaged it as the so-called 5GWiFi.

The 5GHz carrier wavelength is 6 cm, which is criticized for its poor ability to penetrate the wall, and the 60GHz carrier with a wavelength of only 5 mm is basically the ability to "pass through the wall". It will even be blocked by the human body, once the relevant technology is popularized, "you block my signal" will become a fact from a joke, and the fat paper will have another reason to be disliked.

Secondly, the higher the frequency of electromagnetic waves, the easier it is for air molecules to absorb energy, resulting in signal attenuation and affecting the use distance. The WiGig signal is only valid for transmission at a distance of about 10 meters, which can usually only be used in a room, and will automatically slide down to the traditional ISM frequency band if the distance is a little longer, sacrificing speed in exchange for network connectivity.

There is a solution, such as Atletico Madrid, which uses a large number of devices to fill rooms and corridors and bridge them into one with each other, so that the signal range can be infinitely expanded, and you can enjoy the world's leading ultra-high-speed LAN wherever you go.

It's a pity that the resulting investment in equipment is also amazing, that is, a guy like Atletico Madrid, who is not bad for money and is not afraid of radiation, is willing to do this. In fact, after the devices were activated, the electromagnetic intensity of their homes was not increased, but even slightly decreased. This is because wireless devices increase the transmit power to ensure stability when the signal is poor, and decrease the transmit power to extend battery life when the signal is good.

Before the start of the renovation, Atletico Madrid also took photos and posted on Weibo, trying to promote the view that the wireless signal does not hurt people, and the better the signal, the less radiation. As a result, it attracted countless criticisms, and the two sides debated, but it only proved the truth that "those who sleep can't wake up", if he hadn't learned from Zuckerberg to ban unfollowing, he would have lost countless fans.

Building a WiGig network at home is not only to facilitate Tang Jiayi's use of VR equipment, but also to consider "close" observation and data collection.

In the field of wireless communication technology, Atletico Madrid has an advantage that other researchers do not have, after completing the transformation of the cyborg, his skin has the ability to send and receive electromagnetic waves freely, although he can't wear a straitjacket to be an "electromagnetic man", but the cameo as an information collector and communication researcher is also great. Others have to apply for queuing when using a device, and some equipment needs to be redesigned and waiting for manufacturing, but he doesn't need to do this here, and he can occupy the equipment 24 hours a day to collect data, which is naturally easier to produce results.

After the large-scale networking, the research team led by Atletico Madrid soon came up with two black technologies based on WiGig carriers, namely wireless head recognition and wireless gesture sensing technology.

Millimeter-wave radars with carrier frequencies of 30-300 GHz have long appeared on military equipment, such as the seeker at the end of missiles, the big bumps on the heads of armed helicopters, and later gradually appeared on high-end cars. It is small in size and unaffected by weather and ambient light, and is increasingly favored by autonomous driving solution providers.

What Atletico is currently doing is to combine the concept of millimeter-wave radar with WiGig/WiFi technology to use carrier waves to achieve close-range radar imaging. The 60 GHz carrier wavelength is 5 mm, which is reflected and diffracted when it hits the human body, and by analyzing the received electromagnetic signal, it is possible to reverse the approximate shape of the obstacle it encounters/passes, so as to realize the perception of the user.

The wavelength of 5 mm is still a bit large, and it is not possible to obtain high-precision shape information through it, so it can only be recognized with low-precision information because of its simplicity. Fortunately, they only need to be able to distinguish one head from the other, and see the flexion and extension of their fingers, they are qualified, and with the help of bee supercomputing and evolving deep learning technology, they will soon have the results they have now.

Atletico Madrid's ability to "see" the four snacks running over with their eyes closed, accurately grasping the outstretched little hand and easily grabbing the little ear that came over is the credit of these two skills. The problem now is that the accuracy of human recognition is not high enough, and it is easy to distinguish between sesame and biscuits, but it is a little difficult to distinguish between biscuits and sesame sugar.

This is just genetically different siblings, and if you meet identical twins who look basically the same, the system will definitely be blind. The only consolation is that this recognition technology does not require a special activation of the sensor, and the energy consumption is lower than that of face recognition/iris recognition.

Gesture recognition is not such a problem, and now it can recognize all sign language gestures, not to mention daily dots and strokes. It's a pity that they have lost the opportunity and have lagged behind other teams working on millimeter-wave gesture recognition, such as GoogleProjectSoli, who have already come up with a demo prototype and taken the first place early.

The second place is not only easy to forget, but also easy to attack, if they only come up with gesture recognition technology, the bees will have to face the accusation of "following the trend dog".

Fortunately, Atletico Madrid already has an idea to solve the accuracy of head recognition, that is, to bring satellite multi-band remote sensing technology to the ground, and at the same time use 2.4/5/60GHz three bands to perform composite scanning of faces.

Although the images obtained by the first two are more blurry, they can bring a new reference dimension, and can obtain more accurate human head marks through algorithm processing, which can better "recognize the nostrils and distinguish the ears", so as to realize biometric recognition based on electromagnetic waves.

Sure enough, after switching to the new identification scheme, Atletico Madrid's radar vision suddenly became much clearer, although it was still full of large and small blurred squares, but it was already able to recognize the identity. As long as the little one is close to him, he can call out the other person's name, and the accuracy of reaching out and pinching his nose has also improved a lot.

The only problem is that the recognition algorithm still needs to be optimized, and radar recognition does not require additional sensors but requires additional calculations, and the power consumption that was finally saved is burned by the CPU. Atletico's job during this time was to polish the algorithm, then guide the chip team to improve the new ISP graphics processor, and finally build a new demo prototype, and then take it to Las Vegas to plant the flag.

Bees are regular visitors to CES, so naturally they won't miss the Consumer Electronics Show in the new year, and Atletico will lead the team there. America has a new president, and he has to feel it up close and see what changes.

There will naturally be changes, after all, this election is Terrup, the elected Twitter god, he released a lot of cruel words during the election campaign, and he is building the Great Wall on the US-Mexico border, bringing the iPhone factory back to the United States, and withdrawing from the Paris Agreement, the framework of climate change, which will definitely bring a lot of new things.

Atletico were not surprised by his election.

In the eyes of he, the melon-eating masses, Xi Po's donkey party completely lost in IT construction, first Xi Po broke the email door, showing that the former secretary of state lady did not take the security rules seriously at all, and actually built a private server in her own home, and it was easily breached; then her campaign team broke out the second round of email door, the campaign plan, fundraising wishes, publicity plans, and all kinds of insider information in front of people who could not be revealed were displayed in front of the public in an open and honest manner, which seriously damaged the image of Xi Po and the Donkey Party.

And their good friend, Hollywood, the base of liberalism, did not bring a strong enough assist, although many summer blockbusters tacitly appeared female presidents, but with too obvious traces of advertising placement, far less natural and subtle than the previous black presidents.

Although the history of female presidents in film and television dramas is 100 years, the total number is far less than that of male presidents, and there are fewer impressive positive roles. The black president does not have this problem, because because of Hollywood's correct politics, black actors must play a positive and important role in the film, but actresses do not have this talisman.

In fact, the final votes of the two sides were very close, and even Xi Po was slightly more than the other party, becoming the fifth candidate in history to win **** but lose the election.

The reason for this is that America is a federation of 50 states, each of which has a certain element of independence. In general elections, the "winner-takes-all" Electoral College system is manifested, in which a candidate gets a majority of votes in a state and gets all the electoral votes in that state, and in extreme cases, the choice of a handful of swingers can affect a large state, and the swing of a large state can affect an election.

Of course, it could also be "God" who did it.

Irradiating a computer chip with cosmic rays can trigger the so-called "single-event flipping effect", which can lead to errors in computer calculations and thus errors in counting votes. In fact, satellite computers have additional measures to protect against radiation, but terrestrial computers do not, because the threat of rays is basically non-existent, and the charged rays that can destroy the computer system are deflected by the geomagnetic field to the north and south poles to release auroras, which are difficult to reach the ground, and even more difficult to reach the ground beyond the poles.

Rao is so, a computer that can't speak is still a good backbiter. Immediately after the election defeat, some people jumped out and some swing states had abnormal computer counts and called for a recount, which was also quite lively.
