Lost to the selection team twice in a row! The strength of American men’s basketball team is questioned： the prospect of winning the World Cup is worrying.

On August 5th, Beijing time, according to Ben Golliver, the training camp in Las Vegas continued. In two consecutive 10-minute training matches, the American men’s basketball team lost to the sparring selection team. This also makes the strength of the new American men’s basketball team questioned, and the fans of the American men’s basketball team think that the prospect of winning the World Cup is worrying. The American men’s basketball team also took a family photo, and Edwards sat in position C with the ball in his arms.

In the training clips released by the American men’s basketball team, the players of the selection team are in a brave state and constantly break through the defensive scores of the American men’s basketball team, especially Jay Green of the Rockets and Cunningham of the Pistons. The two young people have strong offensive firepower and can also organize attacks. Now it seems that the defense of the American men’s basketball team is very problematic.

Earlier, when the list of American men’s basketball team was announced, many fans ridiculed that it was the worst American team in history. The biggest star in the team is probably Ingram. The most important thing is that they basically have no experience in international competitions. Although these players are promising young people in the NBA at present, the lack of experienced veterans will become a hidden danger.

The official social media of the American men’s basketball team also released the tidbits of taking a group photo. When the American men’s basketball team was photographed, Edwards sat in position C with the ball in his arms, and the timberwolves star was also highly anticipated. The selection team also took a group photo, and Cunningham sat in position C with the ball, beside him was Jay Green.

The American men’s basketball team will play its first warm-up match against Puerto Rico on August 8. Then the American men’s basketball team will go to Spain, against Slovenia on August 12th and Spain on August 13th. Then go to Abu Dhabi, play Greece on August 18th and Germany on August 20th. In this year’s World Cup, the American men’s basketball team was divided into Group C, and the opponents in the group stage were New Zealand, Greece and Jordan.

The US men’s basketball team officially announced the player numbers of the World Cup: No.4 halliburton, No.5 bridges, No.6 Cameron Johnson, No.7 Ingram, No.8 Banchero, No.9 Potis, No.10 Edwards, No.11 brunson, No.12 Hart, No.13 Little Jia Lun Jackson, No.14 Kessler and No.15 Reeves. What do you think they can achieve?

Mei Sen’s four strikers are like paying tuition, but there is no Ivan Tony’s bee.

It seems that losing to Villa in the last round has brought a big impact to Mei Sen.

So in the last home game of the season, Tottenham changed again. In the face of brentford, who is in charge of the suspension of Ivan Toni, Mei Sen showed off Kane, Sun Xingyu, Danjuma and Kulusevski as if to show off how many strikers he had.

The last home game, I want to get more goals in return, at least to give the fans a happy ending. This mood is of course understandable, but Tottenham has not reached the stage of wanting nothing, and theoretically there is still a European war to fight for, so the offensive and defensive balance cannot be relaxed.

As a result, they lost at this point.

At home, the four strikers started, and the effect that Mei Sen wanted appeared at the beginning:

However, only 2 minutes later, brentford completed the counterattack:

After the four strikers, Skip and Bisoma came to the left half, so once they dropped the ball, the right half was empty, which made brentford easily advance to the frontcourt.

Of course, Tottenham Hotspur played at home, and tactically put more power into the attack, and the players put more enthusiasm into it, so they quickly won a set-piece opportunity at the foot of the frontcourt, and Kane made a penalty:

The 11th minute, and therefore played a counterattack:

However, as the momentum of the opening game dropped, Tottenham’s tactical imbalance between attack and defense gradually emerged.

Mei Sen’s four strikers are full of momentum, but the left and right wingers can’t perform the duty of death prevention, and they may not be guaranteed to be in place, so it is inevitable to stand out from the taste of 424 at some moments:

Therefore, as long as brentford crosses the first line of Tottenham Hotspur, it is easy to capture the space of two midfielders:

But on the other hand, Tottenham can also play a threat by relying on its many attackers and outstanding player ability:

Therefore, the game has been developing in the direction of mutual stabbing, but compared with Tottenham, brentford can’t hurt Tottenham for the time being because of the ability of the personnel.

From a certain point of view, strong teams pay so much attention to attack in the league. If their efficiency is high enough, for example, they score three or four goals in this half, then there is nothing to say tactically.

However, Tottenham exhausted a half and scored only one.

On the other hand, if brentford can only play such an offensive efficiency and can’t improve it, it’s no big problem. Tottenham will probably win a thrilling victory at home.

However, brentford has a successful hand, so does Frank.

Back at half-time, Frank took the lead and replaced Oneka with Damsgaard, who was shorter, more flexible and better at finding and using space in the opponent’s back.

This substitution is immediate.

The 50th minute of the game, brentford started to attack from the touchline ball. When Damsgaard caught the ball, there was no defense. After the ball, brentford faced the Tottenham defense, so he was assigned to the weak side and scored successfully:

After the score was equalized, Tottenham could still show its advantage when it had the ball:

Kane also got a chance:

However, as the space around the lower back is more easily used by opponents, the pressure on the defensive end of Tottenham Hotspur is gradually increasing. Even if brentford directly attacks the ribs without mobilization, there is room for starting:

In the 61st minute, brentford directly hit behind him from the right, and Mbeumo scored another goal:

As soon as the goal was scored, Tottenham, who had planned to comfort the fans at the last home, immediately became impetuous, and started with four strikers. Mei Sen has cornered himself. Even if the score is behind now and he needs to score, he can’t play five strikers, can he?

In this way, Lucas Jr.’ s appearance in the farewell game at home has also become a very stressful situation.

On the contrary, on brentford’s side, Frank saw the score reversed and the situation was dominant, while Tottenham put on an attacker with better physical fitness and decisively put on a five-guard. The team also shrank to the backcourt, wholeheartedly protecting the goal and the score, and the ideas off and on the court were very clear.

And even if Mei Sen constantly deployed troops after that, he didn’t shoot many waves in the end, and the precious opportunity besieged didn’t hit until injury time:

At that time, the score was 1-3 because of Tottenham’s own mistakes.

In the end, Tottenham did not escape the fate of losing in the last home game of the season.

In fact, the seed of losing the game started as a four-striker in Mei Sen, but it was planted when only one goal was scored in the first half. It just needs to be seen whether brentford can make it blossom and bear fruit.

So from this point of view, although they lost Ivan Tony, they still have Frank. In half time, Frank clearly saw the obvious defensive problems of Tottenham Hotspur in midfield, so Darmstadt was very accurate at half time, and directly got through his own offensive line, while Mbewu Mo Ye lived up to expectations and seized the most critical two opportunities.

Next season, brentford’s first priority is obviously to find an excellent striker to replace the vacancy left by Ivan Toni after being suspended for a long time. I believe that under Frank’s training and arrangement, their problems will not be great.

As long as you don’t fall behind in the first half, you should at least be able to guarantee the position of the middle reaches next season.

As for Tottenham, their work is obviously much bigger and more difficult.

Sin is the worst! The vice chairman of the Football Association dug up in the Li Tie case is too cunning and has quietly immigrated to Cai Zhenhua.

Tiezi has done meritorious service again! Those "big fish" hidden in the deepest part of the China Football Association have not been exposed in the China Football Association for several years, but they have been dug up one by one in this Li Tie case. Judging from these big fish that have been dug up, the investigation team and the police have a firm and unprecedented attitude towards the phenomenon of "fake gambling on the black" in football. Even if it involves foreign aid, you are welcome to win it.

Since Li Tie was arrested in November last year, as many as 11 people have been arrested in the entire China Football Association system. Including Du Zhaocai and Chen Xiaoyuan, the current second-in-command of the Football Association, Liu Yi, the former secretary-general of the Football Association, Chen Yongliang, who is in charge of the national team, Wang Xiaoping, a calligrapher, and Huang Song of the competition department. There are also Li Yuyi, Yu Hongchen, Dong Zheng and Ma Chengquan who were dug up in the past 10 years. The 11 people who have been arrested are enough for a starting lineup.

According to the South Korean media, the Football Association+Football has been arrested for the "anti-counterfeiting and anti-corruption" in China football this time. Many fans spit out that they can form a "prison" league. There are coaches, a ready-made football association system and players. The only regret is that there is no referee yet.

Judging from the 11 people arrested by the Football Association, the most hidden "big fish" is undoubtedly Li Yuyi who was arrested recently. According to Liu Kai, a former national player, an insider revealed to him that Li Yuyi, who has retired, has quietly emigrated abroad. Because I recently returned to China to handle things, I was directly covered by the police at the airport.

Ran Xiongfei, on the other hand, revealed that Li Yuyi’s immigration is nothing new. In his personal circle, Li Yuyi’s immigration is already a well-known thing. Only before Li Yuyi was arrested, no one expected that he was thinking about immigration because he committed a crime. From this point of view, Li Yuyi is really a wily old fox, hiding everything.

Li Yuyi has retired for five years, and the China Football Association is the last stop of his life. He quite wants to run away after a big ticket in the Football Association.

After becoming the vice chairman of China Football Association, Li Yuyi has always liked to show himself. It was he who put forward the controversial "U23" policy of the Super League. In addition, Li Yuyi likes to take the lead in criticizing the Football Association, saying that the poor football in China is mainly due to the backward management of the Football Association. These words almost touched the hearts of the fans.

Therefore, at that time, Li Yuyi was an out-and-out "good guy" in the eyes of fans and his men. Even after he was taken away, some media people felt sorry for him and felt a little "unexpected".

Judging from Ran Xiongfei’s revelations, Li Yuyi’s real person is really guilty! His main evidence is that he is suspected of economic problems in the Super League company. At the beginning, Super League signed a 10-year 3 billion contract with a brand sponsor, with an annual amount of 30 million, and the leader was Li Yuyi.

At that time, this contract was known as "cabbage price", because a giant like Guangzhou Evergrande alone was worth more than 30 million yuan. However, Li Yuyi packaged 16 teams in the Super League and sold only 30 million. Although all the teams in the Super League stood out against it, Li Yuyi was helpless by hook or by crook, and finally the opposition was invalid. This time, Li Yuyi should have made a lot!

Li Yuyi returned to China this time, mainly to deal with his remaining assets in China. As a result, he was directly covered by the police who were squatting at the airport.

As the evidence of Li Yuyi’s crime was exposed, Cai Zhenhua, the former president of China Football Association, was truly innocent. Because, although Cai Zhenhua was Li Yuyi’s superior at that time, he couldn’t intervene in the affairs of the Super League company. At that time, Cai Zhenhua was mainly in charge of the national team. As for the Super League company, besides Li Yuyi, there were also 16 clubs in the Super League, but Li Yuyi was the one with the greatest voice. Once he wants to do something by hook or by crook, 16 clubs can do nothing.

Many fans may ask why Cai Zhenhua, as Li Yuyi’s superior, didn’t play a supervisory role. In fact, this is an injustice to Cai Zhenhua. Because in 2018, Cai Zhenhua served for four years and left the China Football Association. Subsequently, Du Zhaocai began to dominate the affairs of the China Football Association, and set up a new team of the Football Association. Chen Xiaoyuan served as the chairman of the Football Association, and Li Yuyi stepped down as the vice chairman of the Football Association and was transferred to the Super League as the chairman.

In addition, judging from this investigation by the investigation team, it is mainly aimed at Super League companies, including Yu Hongchen, Ma Chengquan and Dong Zheng, all of whom were in charge of Super League companies. This is a department rich in oil. Once it lacks supervision, they will run amok like runaway savagery.

Fortunately, after Li Tie was arrested, the justice of China football finally came. Those who are ready to run away, those who are ready to retire after making a fortune, and those who are cronyism and regard the Football Association as their home have all been dug up. Although it came a little late, it was not late.

Project Report ｜ Based on ToF technology +AI algorithm, ＂Looking for Blue City＂ launched the ＂Little Blue Lion＂ to create a standard product for intelligent old-age care and fall prevention.

Editor | Wang Yutong

China is accelerating into an aging society. According to the data of the Ministry of Civil Affairs, by the end of 2021, the proportion of elderly people aged 60 and over in China was 18.9% of the total population, and it is estimated that by 2025 and 2035, this number will exceed 20% and 30% respectively. With the acceleration of demographic changes, the urgency of providing for the aged is prominent.

However, China’s old-age service market is still facing the gap between supply and demand of caregivers and places of care. In this context, the state and local governments have successively issued a series of policies to guide the development of the old-age care industry, such as 9073 and 9064, encouraging home-based care (90%), supplemented by community day care (7%/6%) and institutional care as a service supplement (3%/4%). However, due to the gradual reduction in the size of domestic family units in recent years, it is difficult to effectively guarantee the manpower needed for home-based care for the elderly. Therefore, it is still necessary to seek other ways to solve the gap between supply and demand of old-age care.

This provides an opportunity for the popularization and application of scientific and technological products in the pension industry. The smart pension industry has emerged, and enterprises have emerged to develop smart devices for different pension application scenarios and provide health monitoring, data analysis and other services based on technologies such as AI and big data.

In the scene where the elderly need care, falling prevention is considered to be a key link. According to the data released by China Disease Surveillance System, falling is the leading cause of injury-related death among the elderly over 65 years old in China.

In order to prevent the elderly from falling, Shanghai Vision Blue City Information Technology Co., Ltd. (hereinafter referred to as Vision Blue City) launched a series of 3D intelligent human posture sensor "Little Blue Lion" based on ToF radar and AI algorithm, and built a corresponding AIoT platform to provide intelligent care services such as posture warning, health data management and analysis.

Through ToF(Time of Flight) sensor, the electronic equipment associated with it can collect the depth data of environment, objects and human body in the scene, and support real-time imaging. With the help of the algorithm, these data can be used to measure the distance, size and track the movement. The AI algorithm expert model and deep learning network based on ToF depth data can realize accurate recognition of human postures such as falling, sitting, lying and walking. At present, ToF technology has been widely used in face recognition and gesture judgment of smart phones. Other application scenarios include: obstacle recognition of sweeping robot; 3D photography and 3D modeling of intelligent hARdware devices such as ar glasses; Unmanned obstacle identification and ranging.

In addition to the "Little Blue Lion" series products, Trendy Blue City has also developed a smart and healthy SaaS platform to provide integrated intelligent care solutions for residential communities, pension real estate, government and private pension institutions, and home-based pension scenarios. The platform covers daily entertainment life management, health management, home care management, etc., and can integrate health data and service early warning information fed back from AIoT platform.

Vision Blue City was established in 2022 with the joint investment of Shanghai Vision Information Technology Co., Ltd. (hereinafter referred to as Vision Technology) and Zhejiang Blue City Chunfeng Construction Management Co., Ltd. (hereinafter referred to as Blue City Chunfeng).

Vision Technology focuses on AI visual behavior analysis technology, and related products and solutions have been applied in retail, security, smart communities and other fields. Blue City Chunfeng belongs to Blue City Group, a comprehensive real estate service provider. Blue City Group has more than 20 years of experience in real estate development and operation management, with blue city agriculture, blue city support and blue city health as its core service industries.

In terms of products, Shan Yiyong, CEO of Trendy Blue City, told 36Kr: "At present, millimeter-wave radar is the main anti-fall technology product used in the smart old-age scene on the market. Compared with RGB cameras, millimeter-wave radar can identify height changes and protect the privacy of the elderly. However, the accuracy of millimeter-wave radar identification is poor, and the probability of attitude false alarm is high. ToF radar can significantly improve the accuracy of attitude reporting while protecting the privacy of the elderly. "

In addition, Vision Blue City will launch the whole industrial chain products based on the combination of body recognition and health care, aiming at systematically collecting human micro-expressions and all kinds of movement data, and using AI technology to realize comprehensive health assessment, rehabilitation and sports guidance, service demand reporting and other functions.

On the one hand, the accuracy and privacy of "Little Blue Lion" series products are double guaranteed because ToF scheme itself has certain technical advantages compared with other technical routes such as millimeter wave radar and laser radar. At the same time, in recent years, the hardware module of ToF sensor has made some progress in technology. On the other hand, it benefits from the technology accumulation of vision recognition AI algorithm.

First of all, the technical advantage lies in the higher privacy protection of imaging, but the collected posture data is clearer and richer. On this basis, supplemented by three-dimensional spatial data,Vision Blue City can use AI technology to make a more accurate judgment and analysis of the user’s posture and behavior information.. Shan Yiyong, CEO of Vision Blue City, said: "The low accuracy of millimeter-wave radar is mainly due to the low amount of data available at present, which can only be used for mechanical judgment and it is difficult to use AI technology. And each of our ToF devices has an AI chip, which can be directly judged. "

Compared with the imaging of other radar sensors

Blue ToF-3D sensor imaging

At present, the ToF sensor applied in Blue City has a maximum distance of 8 meters and a resolution of 640*480. Shan Yiyong, CEO of Vision Blue City, pointed out: "It is very important to improve the collection distance and resolution. In 2021, the ToF sensor module can only support the acquisition distance of 6 meters. By 2022, this number has increased to 8-10 meters. In addition, at the resolution level, it has reached a level similar to VGA, which is enough to clearly distinguish human posture and behavior. "

Secondly, the improvement of the accuracy of body recognition needs the support of corresponding AI algorithm and model, and the model is continuously optimized through a large amount of data. In the early stage of vision technology, a large amount of data has been accumulated for deep learning, and it has a mature model.

Looking forward to Blue City can directly call its ready-made model and quickly write the device algorithm..

At present, the technical team led by Dr. Zhong Zhang, the chief scientist, has solved two ToF technical difficulties.

First, through data modulation, the remote depth data drift can be controlled. According to reports, in the traditional sense, after the monitoring distance reaches 8 meters, the drift distortion of depth data will be more serious;

Secondly, based on deep learning algorithm and expert model, the accuracy of posture recognition is improved. Shan Yiyong, CEO of Vision Blue City, told 36Kr: "There are scenes where deep learning can’t achieve accurate recognition, such as scenes where human feature data is completely or partially lost due to the covering or blocking of obstructions. For example, the elderly may fall behind the coffee table, and ToF equipment can’t capture the portrait behind the coffee table. At this time, the traditional deep learning system will have false positives, but we can infer through the memory and analysis ability of the expert system. "

In the view of blue city, this expert system is also the core technical barrier of the company at present, which can help it build a certain first-Mover advantage.. Shan Yiyong, CEO of Blue City, pointed out: "There are still few people doing things with this technology, and some people do it, but the landing is slow."

On the market side, relying on the resources of Blue City Group and its affiliated enterprises in the real estate industry, it is tending to see that Blue City has signed some old-age real estate projects, such as Hangzhou Blue City Taoranli, etc., with CCRC community and high-end old-age care institutions as the main formats. It is estimated that there will be more than 10 landing projects this year, and mass production will be realized in May, and about 10,000 products will be delivered to customers.

But at the same time, by looking at the technical advantages and resource advantages that Blue City has at this stage, it may face two corresponding challenges at the market level.

First, the product price is high, while the market’s willingness to pay and purchasing power are still low.

From the cost side, Shan Yiyong, CEO of Vision Blue City, said that every ToF device is equipped with AI chips, which leads to the fact that the price of ToF devices cannot be directly reduced to the same cost level as ordinary radar sensors. From the demand side, market education and fee payment are considered as two obstacles for the domestic pension market to move from just-needed pension service to refined management mode of CCRC.

At present, the equipment of Blue City is priced at 2000 yuan. Usually, one piece of equipment needs to be placed in the toilet, bedroom and living room respectively, that is, a single household needs to pay at least 6000 yuan for the equipment. Shan Yiyong, CEO of Vision Blue City, said frankly that this is one of the main reasons why Vision Blue City should first cut into the market from CCRC community and high-end pension institutions. But at the same time, he also said that with the increase of output in the future, the price of external mining modules will decrease; In addition, through the back-end "module+self-developed motherboard" form, the company is expected to achieve a continuous decline in costs, and the price of a device in the future can be reduced to around 1000 yuan.

Second, it remains to be verified whether the existing industry resources can continue to play an advantage in the process of product penetration to B-end customers, G-end customers and C-end customers except affiliated enterprises.

Generally speaking, the business model of Blue City at this stage is mainly divided into two categories: BtoBtoC and BtoGtoC, and the goal of the next stage is to directly face C-end users.

Under BtoBtoC mode, B-end customers such as CCRC community and pension real estate may pay more attention to the actual economic value that the equipment can create for the project, whether the new project adopts ToF scheme or not, and whether the completed project is replaced by ToF scheme. This, in turn, depends to some extent on whether the value of the equipment can be recognized by C-end users. Specifically, the first is the weight of ToF scheme in the decision-making process of users choosing pension institutions; The second is whether users are willing to pay a premium because of the adoption of ToF scheme.

In addition, the body recognition products of Blue City only solve a small part of the needs of the elderly-real-time care and immediate feedback. In the provision of follow-up services, professional institutions and service personnel are needed to fill in. Therefore, whether the adoption of equipment can actually reduce the demand of nursing staff, improve the efficiency of care, improve the reuse rate of personnel and reduce the cost of care may also constitute a part of the core considerations.

Under the BtoGtoC model, the government pays more attention to the creation of social value. Although Vision Blue City proposed a subscription payment model to solve the problem of high equipment cost, as mentioned above,Whether you can achieve synergy with back-end services may be the key.. This is equally important for the C-end users themselves.

In this way, doing a good job in extending the form of products and services and establishing a reliable partnership with upstream and downstream enterprises in the industrial chain may be the future concern of Blue City.

In this regard, Trendy Blue City said that it would explore the form of "property+"and reach a cooperation with the property company. Trendy Blue City is responsible for the provision and basic operation of smart devices, and the property is responsible for the service output after posture warning. In this mode, residents in the community can also pay in the form of equipment and service subscriptions. However, this cooperation model may face some difficulties in actual implementation, such as the delineation of related responsibilities and the ability of the property to provide related services.

At present, the team is mainly composed of R&D personnel, and a marketing team is being established.

Dr. Zhong Zhang, the founder and chief scientist, graduated from Tsinghua University and worked as the chief scientist of OBJECTVIDEO, the world’s first visual behavior analysis company, for nearly 10 years, leading the team to develop an industry-leading expert algorithm model. At present, based on the deep learning model, Dr. Zhong Zhang has built a mature technical path of "expert model system+deep learning system".

Founder and CEO Shan Yiyong has worked in Kangyang Real Estate Head Enterprise for nearly 20 years. He has participated in the planning, construction and operation of many industry benchmarks Kangyang Real Estate projects, and has also participated in the establishment of health management companies and launched O2O community health management solutions based on IoT.

Dr. Mei Jian, founder and CFO, has more than 20 years of experience in the financial industry and 3 years of entrepreneurial experience in the real estate consulting industry. He used to be the chief information officer of state-owned and joint-stock commercial banks and the president of the investment banking department.

Other core members of the team have many years of experience in artificial intelligence, IOT and other fields.
