Original title: Google Maps New feature: Lock screen interface can also be navigated in real time

Recently, Google Maps has launched a new feature that reflects your location in real time and provides real-time navigation support, which can guide you in real time on how to go, where to take the bus or subway.

Although the existing navigation can still implement voice and other navigation, providing you with various itineraries, unlike the existing map navigation, the application is updated in real time and can be accurate to every step, including reminding you that it is time to get off, turn left or right, and so on.

The reminder function can not only be reminded on the application interface, but also on the lock screen of the mobile phone, allowing users to complete the navigation function without entering the Google Maps application interface, which is also a lack of existing navigation maps.

Google will randomly select some customer engagement tests in the near future. You can check whether Google Maps can be upgraded at any time. If you are lucky, you will be given priority to experience the portability brought by the new features of Google Maps.

　　Collecting artificial joints will benefit more people. (Comic Source: vision china)

　　After coronary stent (heart stent), another high-value medical consumables "group purchase" was successful. Recently, the state organized the centralized procurement of artificial joint products in Tianjin, and the procurement products included the initial total hip replacement and the initial total knee replacement. The procurement period was two years. The results show that the average price of hip joint has dropped from 35,000 yuan to about 7,000 yuan, and the average price of knee joint has dropped from 32,000 yuan to about 5,000 yuan, with an average decrease of 82%.

　　"It is really a good thing that medical consumables have been greatly reduced, making people feel more at ease and emboldened to see a doctor." During the interview, many readers expressed their jubilant feelings to the reporter. When will the new price of artificial joints land? How much cheaper can the total cost be? What is the clinical situation of the new price of cardiac stent that has been implemented for more than half a year? How will the centralized purchase of high-value medical consumables develop? Guangzhou Daily’s all-media reporter recently conducted an investigation.

　　Text, map/Guangzhou Daily, all-media reporter Feng Qiuyu

　　The average price reduction is over 80%

　　It is expected to land in March-April next year.

　　It is understood that this procurement of artificial joints has attracted more than 40 enterprises at home and abroad, bidding for more than 800 products, covering artificial hip joints and artificial knee joints. The planned procurement volume is 540,000 sets, accounting for 90% of the demand of the whole medical institution. According to the purchase amount in 2020, the purchase amount of two kinds of joints in public hospitals is 20 billion yuan, accounting for 10% of the high-value medical consumables market. According to the average decline of 82%, it can save more than 16 billion yuan every year.

　　This artificial joint collection is the first time in the field of orthopedic consumables at the national level. Since 2019, Anhui, Jiangsu, Fujian, Shandong and other provinces have also carried out the collection of artificial joint consumables, with an average decline of 32.12% to 86.26%. After the state organizes the procurement of artificial joints, the related products will be applied to public medical institutions in the alliance area. On October 9, the reporter learned from an interview with the joint procurement office of high-value medical consumables organized by the state that the price and use plan of the selected products in centralized procurement will be implemented from March to April, 2022. "The specific implementation date is determined by the regions of the alliance."

　　According to the National Procurement Document of Artificial Joints with Concentrated Quantity (GH-HD2021-1), after the implementation, the hospital signed a procurement agreement with the selected enterprises on the national joint procurement platform for medical consumables. Yang Li, a senior researcher at Guangzhou Zhongcheng Medical Machinery Research Institute, said that from the perspective of national and previous provincial-level procurement of artificial joints, the price of the selected artificial joint terminal dropped by about 60%~90%, and patients enjoyed relatively cheap and high-quality medical consumables.

　　About 2/3 patients were not operated because of the cost.

　　Centralized purchasing is expected to popularize domestic consumables

　　Artificial joint replacement is one of the effective methods to treat femoral head necrosis, joint injury, osteoarthritis and other diseases caused by trauma, sports injury, degeneration and aging, which can greatly restore the joint movement function of patients and obviously improve the quality of life.

　　Zhang Xu, director of the Department of Orthopaedics, Yueyang People’s Hospital, Hunan Province, said that hip fracture in the elderly is often called "the last fracture in life". If you stay in bed for a long time with conservative treatment, it is easy to cause thrombosis and lung infection, which belongs to the "just need" in the operation of replacing artificial joints. Generally, for hip fractures in the elderly over 65 years old, surgical treatment (joint replacement) is the first choice.

　　"The other part ‘ Not just needed ’ Hip and knee are the main joints. Osteoarthritis and rheumatoid arthritis caused by various reasons, physical deformity affects appearance and walking pain affects daily life. Joint replacement is the best treatment. In the past, due to the high price of replacement joints (joint prosthesis materials) and economic conditions, many patients who needed replacement surgery gave up. " Zhang Xu said that in some second-and third-tier cities and rural areas, there are more cases where treatment is delayed due to high costs. "From the clinical situation, at least two-thirds of patients choose not to have replacement surgery for economic reasons."

　　Artificial joints belong to high-value medical consumables. In the past, according to the bidding price and different preferential efforts of manufacturers, the pricing of hospital consumables at different levels was not exactly the same. A doctor in a 3A hospital in Shanghai said that the cost of artificial joint replacement in this hospital is between 50,000 and 70,000 yuan, and the medical insurance can be reimbursed about 20,000 yuan. After centralized procurement, the price before medical insurance reimbursement is expected to drop to 20,000 to 30,000 yuan. Zhang Xu introduced that at present, the average cost of knee replacement surgery in Yueyang People’s Hospital is more than 20,000 yuan except joint consumables, and the personal burden is about 50%; The average consumables is more than 20,000 yuan, and the personal burden of medical insurance for employees is about 70%, and the reimbursement is capped at 8,000 yuan. Therefore, after medical insurance reimbursement, individuals need to bear a total of about 24,000 yuan. After the collection, the price of mainstream knee products has dropped to around 5,000 yuan, and with medical insurance reimbursement, ordinary people can spend a lot less, and the average total cost has dropped by more than 40%, which is acceptable to most people.

　　An orthopedic surgeon in a 3A hospital in Guangzhou said that the price of hip consumables used to be as low as 10,000 to 20,000 yuan domestically, and as high as 100,000 yuan imported. The price of consumables is much higher than that of surgical treatment and medical expenses, which add up to about 15,000 yuan. "After this collection, it is expected to reduce the economic burden of patients. In the past, some patients used to choose imported consumables, and collection is also expected to popularize the use of domestic consumables."

　　According to statistics, in 2019, the number of artificial hip and knee replacement operations in China has exceeded 900,000, and it has maintained an annual growth rate of about 20%; By the end of 2020, China’s elderly population over 60 years old accounted for 18.70%. Yang Li, a senior researcher at Guangzhou Zhongcheng Medical Machinery Research Institute, believes that for the middle-aged and elderly people who need such products, the national centralized procurement is undoubtedly a major benefit.

　　Most of the heart stents fell to 700 yuan.

　　Guangdong’s procurement progress exceeds agreed expectations.

　　We still need to wait for a short time for the price reduction brought by the centralized procurement of artificial joints, and the price reduction of cardiac stents has already landed in Guangzhou. Yang Li introduced that last year, the price of coronary stents purchased by the state with centralized quantity dropped by more than 94%, and the average price dropped from 13,000 yuan each to around 700 yuan, which was very strong and was implemented on January 1 this year. Liu Zhen, deputy director of the Department of Cardiovascular Medicine of Guangzhou First People’s Hospital, told the Guangzhou Daily all-media reporter: "The price of heart stent collection has been on the ground for some time. This collection is indeed very strong, and other ancillary products have also entered the rhythm of collection."

　　As a doctor who has been engaged in cardiovascular medicine for more than 20 years, Liu Zhen has to perform hundreds of operations every year, and the heart stent can be said to be his "most familiar old friend". "In previous clinical applications, cardiac stents were made in China and imported. The domestic price was between 8,000 yuan and 11,000 yuan each, the imported price was around 20,000 yuan each, and the employee medical insurance reimbursement was about 70%; At present, the products collected in clinic will be given priority. The price of domestic and imported cardiac stents is mostly more than 700 yuan or even lower, which greatly reduces the burden on patients. "

　　It is understood that before this, Guangdong Province reported to the National Joint Procurement that the total demand for stent procurement in the coming year was 112,500, accounting for 8.4% of the country, and the usage ranked second in the country. According to the national centralized procurement document of coronary stents, the agreed procurement volume in the first year is 80% of the total procurement demand, that is, the intentional procurement volume in Guangdong Province in the first year is 90,108, which is estimated to save about 1 billion yuan compared with the average online price in Guangdong Province. According to the disclosure of Guangdong Medical Insurance Bureau, by the end of August this year, 132 hospitals in Guangdong Province had purchased a total of 82,427 stents selected in national centralized procurement, and the procurement progress exceeded the agreed expectations.

　　Expert: Centralized purchasing has become an inevitable trend.

　　Ordinary people are the biggest beneficiaries.

　　"The purpose of medical reform is to make the people afford to see the disease, see the disease well, and see the doctor conveniently. Drugs and consumables have been greatly reduced in price round by round. In the future, the collection of high-value medical consumables will further expand the scope of procurement, and all parties concerned will work together to ensure the orderly development of collection and use. " Experts in the industry believe that in the next step, it has become an inevitable trend to quickly start centralized purchasing with products with large clinical dosage and mature use.

　　"After the collection of coronary stents and artificial joints, the national medical insurance department has a comprehensive understanding of the price formation of the products of the bidding enterprises, which helps to form a scientific and reasonable pricing system. While the price of artificial joint consumables is greatly reduced, how to ensure the quality of products needs to be focused on. " Liang Jialin, secretary-general of the Expert Committee of Value Medical Consultants, believes that the efficacy of drugs in use is mostly short-lived, but implantable consumables (coronary stents, artificial joints and intraocular lenses) are mostly long-term or even accompany patients for life, so we should not only consider the quality of the products themselves, but also continuously track and monitor the medium and long-term efficacy. "In the next stage, the national level can explore the monitoring of the quality and efficacy of the winning products from the national specialized medical association of the National Cardiovascular, Orthopedic and Ophthalmic Medical Center."

　　Yang Li, a senior researcher at Guangzhou Zhongcheng Medical Machinery Research Institute, believes that, unlike stents (especially traditional metal stents), there is still much room for improvement in the overall permeability of orthopedic track. After purchasing with quantity, it is expected to usher in a significant increase in category usage, and the most important thing is that the majority of patients will benefit. "The overall market concentration and standardization of the industry will be further enhanced. After the price drops sharply, the market demand for products will increase significantly. In the long run, the industry penetration rate and market space will increase. For related manufacturers, especially those with a high proportion of revenue in this business, it is necessary to quickly improve their cost control and operation capabilities to ensure supply after winning the bid. If you fail to win the bid, you should determine the business choice and market expansion measures as soon as possible. "

On August 16th, Zhiji Automobile held an IM AD DAY Intelligent Driving Conference in Tsinghua Science Park. At the meeting, two alumni of Tsinghua University-Guo Hui, deputy CTO/ of Zhiji/Chief Scientist of Intelligent Driving of Zhiji Automobile, and Cao Xudong, CEO of Momenta, joined hands with Professor Shengbo Eben Li of Tsinghua University Institute of Vehicles and Transportation to discuss and analyze the technical route, experience standard, development trend and many other topics of autonomous driving.

Professor Shengbo Eben Li of Tsinghua University pointed out that safety is the first demand of self-driving cars, and data-driven brain-like control technology is the best way to solve the driving safety dilemma. Cao Xudong, CEO of Momenta, predicted that based on DDOD, DDLD and D.L.P artificial intelligence models, iAd intelligent driving will be fully data-driven, and most scenes will be automatically driven in the next 3-5 years.

Guo Hui, chief scientist of Zhiji automobile intelligent driving, said that Zhiji has completed the technological evolution track of head players’ intelligent driving for 9 years in 2 years, and has reached the user experience of intelligent driving products 3.2 times of human driving safety; And announced the "road map for the landing of Zhiji automobile intelligent driving products in the next 3 to 5 years". He also revealed that Zhiji cycling will officially open the "IM AD City NOA" beta in October this year, and step into the "urban NOA era" simultaneously with the global head players.

In recent years, the intelligentization vigorously promoted by the new forces of making cars has become the consensus of the future development of the automobile industry, and has made rapid progress. In this process, Zhiji Automobile has demonstrated its strong technical ability and achieved extraordinary development speed.

In just two years, Zhiji has completed the nine-year intellectual driving road for head players. From the road map:

"Go to the high-precision map NOA", IM AD will open the public beta in September;

"City NOA", which started internal testing in April this year, is progressing smoothly and will start public testing in October;

"Commuting mode" is expected to quickly cover 100+ cities nationwide in 2024;

In 2025, IM AD will enter the era of Door to Door.

In the next 3~5 years, Zhiji Automobile will start the intelligent driving products to run at an accelerated speed, and the intelligent driving products such as high-precision map NOA, urban NOA and commuting mode will be intensively launched.

Experience is better than the industry’s head level.

At the same time of rapid evolution, high-standard intelligent driving experience is the highest value appeal of Zhiji automobile. IM AD, the intelligent driving assistance system of Zhiji automobile, not only surpasses most human drivers in safety, traffic efficiency and road game ability, but also provides users with an experience obviously superior to the industry standard.

Especially the safety, at present, Zhiji Automobile has achieved intelligent driving 3.2 times the safety of human driving. The statistical results of actual driving data show that at present, the number of collision accidents per million kilometers of IM AD is 0.6, which is far lower than the number of collision accidents per million kilometers driven by human beings, which provides a solid security guarantee for the user experience of man-machine driving. IM AD’s safety class false braking frequency is less than once per million kilometers, which is 5 times better than the industry head standard.

In terms of performance experience, IM AD’s delivery standards are equally strict, whether it is "driving performance" such as lane-changing efficiency, driving center performance, driving fluency and driving comfort, or "parking performance" such as parking space recognition ability, parking success rate and parking fluency, all of which exceed the level of the industry’s top players; The success rate of IM AD lane change is as high as 98%, the uncomfortable deceleration is only 1.3 times per thousand kilometers, and the success rate of parking is 97%. It can be called a typical "hexagonal warrior".

All data-driven accelerated evolution

As a new brand, behind the distance between Zhiji Automobile and its head players for two years, it is the underlying technical advantages of joint development and two-way empowerment with Momenta-the core competence composed of more efficient architecture, rapidly evolving algorithms and higher utilization of generative data, which will continue to drive the accelerated evolution of iAd.

IM AD is the only dual-intelligent computing platform compatible with Xavier and Orin, and its architecture adaptability is more efficient, the computing power demand is reduced by 90%, and the running efficiency of the model is greatly improved by 500%. Based on this, limited computing power can also achieve global visual integration; Only the scheme of "single lidar+single Orin chip" can also cover all urban scenes and meet the needs of NOA for high-precision maps.

At the same time, IM AD algorithm has faster technical evolution ability. In 2021, OneModel, BEV and Transformer technologies have been implemented, and in 2022, the first car was equipped to achieve mass production, laying the industry-leading technology base. In April 2023, Zhiji Automobile and Momenta released the industry’s first D.L.P artificial intelligence model, which solved the bottleneck problem of cognitive intelligence. The "NOA-to-high-precision map" public beta, which will be launched in September this year, will gradually realize the switching of map technology schemes and realize the uninterrupted assisted driving experience without relying on high-precision maps. On this basis, in 2024, IM AD is expected to enter the application stage of Occupancy occupying the network and realize automatic driving in most scenarios.

Intelligent driving products land at high speed

　　Core reading

　　The pseudo base station is called by everyone, but how can it show its original shape? Guangdong Mobile uses big data to deploy tight encirclement. According to the cell phone signal data, timely warning; End, tube and cloud data linkage to accurately identify pseudo base station short messages; Cooperate with the police to locate the attack. The data shows that the activity of pseudo base stations has dropped significantly.

　　"Dear users, hello. You get the discount of sending 50 yuan to 100 yuan. Click wap.××××××.com to recharge, which is limited to this machine. China Mobile. " Seeing this message from "10086", Zhang Xuewei hesitated and felt that the recharge website was suspicious. Fortunately, another early warning message from China Mobile came immediately, reminding him that he might have been attacked by a pseudo base station just now.

　　As a common tool of criminals, the harm of pseudo base stations has attracted the attention of the whole society. If you impersonate a bank to send a short message with a virus link, once the user clicks on the link, it will lead to cell phone poisoning, privacy information being stolen, and then property losses will be caused.

　　Zhang Xuewei is located in Foshan, Guangdong Province. This time, he accepted the free early warning service of pseudo base stations independently developed by Guangdong Mobile based on big data. The service was piloted in Foshan, Jieyang and Chaozhou at the beginning of November last year, and so far more than 600,000 users have been reminded.

　　Use signal data to see through pseudo base stations and give early warning in time.

　　Normal base station: "Where does your signal come from?"

　　Mobile phone: "I came from a base station."

　　Normal base station: "No, I don’t even know this guy. It’s definitely not ours ‘ Little friend ’ ！”

　　The normal base station keenly found that the mobile phone had been held by a pseudo base station, so it reported it to the network system.

　　When Zhang Xuewei received the fraudulent short message, the above "conversation" started between the normal base station and his mobile phone.

　　Pseudo base station is an illegal device that does not access the operator’s network, and it can simulate any number to send illegal short messages. "It’s a base station, but there are actually two small boxes." Along the direction of Liu Shaocong’s finger in Guangdong Mobile Wireless Optimization Center, two "iron boxes" are lying on the table, one is smaller than the computer case, and the other is only the size of a shoe box.

　　At present, the pseudo base station technology and price threshold are very low. Moreover, as the volume shrinks, the forms of crime are more diverse: some throw pseudo base stations next to roadside garbage bins; Some put it in their backpacks and get on the bus to move and signal; And hire someone else to carry it, hide in the dark and send it remotely with a mobile phone … …

　　However, "no matter how cunning a fox is, it can’t fool a good hunter." Pseudo-base stations switch mobile phone signals with stronger power, which also becomes a breakthrough for technicians to detect pseudo-base stations. Simply put, when a mobile phone that has been held hostage by a pseudo base station signal is reconnected to the normal base station network, it will bring the relevant signal data of the pseudo base station.

　　"At this time, big data will come in handy." Liu Shaocong said that the abnormal signaling found by the normal base station will be uploaded to the network and compared with a large number of normal signaling, and finally it is determined that this unknown guy is a "bad guy." Then, an early warning message will be sent to the user’s mobile phone.

　　End, pipe and cloud data linkage, accurate identification

　　Pseudo base stations can change their numbers at will. In a bunch of normal short messages, how can we find out the fraudulent information at once?

　　Xu Jiajun, who works in Guangdong Mobile Network Management Center, took out a mobile phone with an APP application — — Safety pioneer. With the captured pseudo base station, he sent a test message; Then, open the security pioneer and click "pseudo base station identification". In less than 30 seconds, a short message "stands out" from hundreds of short messages in the inbox. At first glance, it is the one just sent.

　　This self-developed "pseudo base station SMS identification technology" is also based on big data. Collect short message features through the mobile phone terminal, compare them with a large number of short message features of pseudo base stations stored in the cloud library, and check the transmission pipeline at the same time. Generally speaking, whether a mobile user sends or receives a short message, it is recorded in the short message center. If it is not recorded and matches the above characteristics, it can basically be judged as a pseudo base station message.

　　This big data identification technology, which adopts the linkage of end, pipe and cloud, can identify the short messages of pseudo base stations in the province’s ports. The advantage of security pioneer lies in not only the data of mobile phone terminal, but also the data of short message transmission pipeline.

　　Real-time calculation, with the police positioning strike

　　"There is pseudo base station activity near Chebei subway station in Tianhe District". According to the monitoring of Guangzhou Mobile, technicians immediately rushed to the scene to track with instruments.

　　A man riding an electric car came into sight. At first glance, his dress is no different from that of ordinary food delivery staff, but this disguise can’t escape the "eye-catching" of technicians. After the alarm, the public security personnel quickly arrived to control the man and seized a set of pseudo base station equipment from the disguised takeaway box on the spot.

　　Here, the "golden eye" is the "pseudo base station detection and tracking system". "Big data detection, early warning and accurate identification, if only used to remind users ‘ Don’t be fooled ’ The intensity of cracking down on pseudo base stations is undoubtedly greatly reduced. We not only passively prevent, but also take the initiative to cooperate with the public security organs to pull out the pseudo base station. " Kang Yong, the security director of Guangzhou Mobile who is responsible for the pseudo base station attack, said.

　　On the basis of detecting and warning short messages from pseudo base stations, the system performs big data processing to lock a large area where a user’s mobile phone is attacked by pseudo base stations at the same time or continuously; Then analyze the location and moving path of each mobile phone and calculate the accurate location of the pseudo base station.

　　"The current pseudo base stations are often in motion, which requires higher real-time computing power for big data." Liu Shaocong revealed that with advanced positioning technology, the positioning accuracy of pseudo base stations can be controlled at around 100 meters.

　　In the current high-pressure situation of cracking down on telecommunication network fraud, Guangzhou police have treated the pseudo base station case as a major warning and established a linkage mechanism with Guangzhou Mobile. Once the location of the pseudo base station was located in the system, the police immediately dispatched police forces nearby to jointly attack with the road patrol personnel sent by Mobile. As soon as the suspect is identified, arrest him immediately.

　　Since 2015, Guangdong Mobile has cooperated with public security organs to crack 818 cases of pseudo base stations, arrested 1,095 suspects, seized 985 sets of pseudo base station equipment and 456 vehicles, which effectively shocked the illegal and criminal activities of pseudo base stations. According to the relevant network data of Guangdong Mobile, the number of abnormal registration location updates caused by pseudo base stations decreased by 57% year-on-year, indicating that the activity of pseudo base stations decreased significantly.
