South Korean media quoted an unidentified industry source as saying that Samsung will develop a chip that can calculate data collected by various sensors installed in self-driving cars, or by exchanging information in real time with Google data centers , thereby centrally controlling vehicle functions. The report also added that the project is expected to be carried out by Samsung’s logic chip development division.

Waymo, one of the world’s many self-driving technology research companies, is considered a leader in the self-driving industry and has begun offering a small-scale self-driving ride-hailing service in Chandler, Arizona. Previously, Trent Victor, the company’s director of safety research, said: “We believe there is an opportunity to replace human drivers with Waymo drivers, thereby improving road safety.”

Self-driving cars are equipped with complex technology and advanced chips, so only the best components can be used in self-driving vehicles, and Samsung is one of the world’s leading manufacturers of advanced logic chipsets, and the cooperation between the two parties may produce good results.

All along, Samsung has been actively looking for new chip customers. In the long run, the partnership with Waymo may bring more new customers to Samsung. At present, the self-driving industry is developing rapidly. If Samsung can prove its ability to become a reliable partner of Waymo, it is very likely that more self-driving technology companies will seek its help in the future.

The empowerment of 5G provides new possibilities for the construction of “smart hospitals”

The concept of “smart medical care” has a long history, and the exploration of informatization construction has never stopped. In 2018, Shantou launched the Three-Year Action Plan for Information Infrastructure Construction in Shantou (2018-2020); in 2019, it launched the Action Plan for Accelerating the Development of the 5G Industry in Shantou (2019-2022), which requires the active promotion of 5G technology. Integrated development with medical and health care, and effective in medical and health institutions at all levels.

The empowerment of 5G provides new possibilities for the construction of “smart hospitals”. On the other hand, looking at the construction of “Internet + medical care” in Shantou in recent years, we can see that under the multiple drives of policy support, market demand and the background of the epidemic, the construction of smart medical care in Shantou presents a new scene.

PDA has modules such as patient information list, doctor’s order inquiry, doctor’s order execution, nursing documents, vital signs, infusion monitoring, allergy management, specimen collection, supplementary bookkeeping, and memorandum. By scanning the wristband, the patient’s identity can be checked, the PDA can query the patient’s doctor’s order, and the doctor’s order can be checked by scanning the matching two-dimensional barcode on the patient’s wristband and the drug label, preventing medication errors, and accurately recording the execution time of the doctor’s order and the execution of the nurse. and other information, record the infusion process in an objective and detailed manner, and reduce and avoid the occurrence of adverse infusion reactions.

Nurses enter the patient’s condition in real time at the bedside, and will automatically generate temperature sheets, nursing records, and various assessment sheets; when nurses visit patients, they scan the 2-dimensional barcode of the ward to automatically generate real-time inspection records, ensuring graded nursing inspections. implementation of the system.

During the epidemic, how to reduce the risk of cross-infection while meeting the demand for medical treatment is an important issue for hospitals and patients. Internet hospitals stand out by virtue of their advantages of contactless medical treatment, and many Shantou hospitals have joined the launch one after another, and the introduction of multi-functional self-service terminals has opened up online and offline links.

It is one of the specific applications of 5G empowerment. On October 19, 2020, Xiao Zhe, the chief physician of the neurosurgery of the hospital, used this form to perform two brain surgeries, the left middle cerebral aneurysm microsurgery and the craniopharyngioma microsurgery. Live broadcast nationwide.

Guided by the health needs of local populations, Smart Health has released smart health products such as National Health Information Interconnection, Smart Home-Medical Cloud, and Smart Maternal and Child Cloud. And through scenarios such as graded pre-diagnosis, collaborative diagnosis and treatment, online services and comprehensive management, efforts are made to realize the county-level medical community.

Smart Interconnect adheres to the development concept of innovation, interconnection, integration, openness and sharing, and builds a new service model of “Internet + medical health”. The product series involves Internet hospitals, prescriptions, nursing care, commercial insurance, payment and other aspects to realize the interconnection of medical care and various aspects.

Smart IoT takes the basic medical Internet access platform as the core, applies the smart hospital IoT technology system and IoT multi-network integration network architecture, covers three aspects of patients, medical care and hospital management, and integrates with the information system to promote medical services. Full process automation. Actively explore innovative applications in the field of 5G smart medical care, and jointly promote the construction of telemedicine, regional cooperation, smart medical treatment, smart IoT, artificial intelligence and medical informatization,

Utilizing the “large bandwidth, low latency, and high reliability” features of 5G, functions such as data collection and real-time transmission of emergency equipment between ambulances and hospitals, and high-definition audio and video interaction (rescue guidance) are realized. In the future, in the pre-hospital emergency linkage system supported by 5G technology, from the moment the patient is lifted into the 120 ambulance and the emergency personnel touch the patient, the patient’s basic physical sign data, condition assessment images, and emergency condition records will be displayed in the form of data. The millisecond-level speed is transmitted to the hospital emergency center in real time without damage, and 120 ambulances and the hospital emergency team have a “zero jam” remote video call to discuss and guide the pre-hospital treatment plan. At the same time, the 5G network can also efficiently plan and optimize the design of the emergency diagnosis and treatment process, thereby shortening the response time from pre-hospital calls to in-hospital emergency response, and striving for greater vitality for patients.

In terms of patients, Smart IoT provides location navigation services and convenient family escort services for patients through the hospital navigation system and shared escort room; in terms of medical care, a digital ward has been established, which allows doctors and nurses to clearly grasp the location and condition of patients. , infusion situation, etc.; in terms of hospital management, it provides full business process management for the hospital’s logistics operation and maintenance, including IT operation and maintenance management, environmental energy consumption management, medical waste management, etc., using information systems and sensor monitoring equipment to achieve operation and maintenance Managed intelligent services.

Purdue University researchers are developing an integrated medical sensing platform

Researchers at Purdue University are developing an integrated biosensing platform designed to detect and monitor mosquito-borne diseases faster and cheaper than existing methods to help prevent viral outbreaks and their devastating effects.

Lia A Stanciu, Purdue Professor of Materials Engineering, is leading the research and development of the technology. The other researchers are Ernesto Marinero, professor of materials engineering and electrical and computational engineering; and Richard Kuhn, professor and department chair of biological sciences and director of Purdue University’s Institute of Inflammation, Immunology and Infectious Diseases. Kuhn also led the first research team to determine the structure of the Zika virus.

“More than one billion people in the world suffer from one or more neglected tropical diseases (NTDs). These diseases, such as dengue fever, yellow fever and West Nile virus, are classified as NTDs because they are largely Impacting the poor in developing countries is a low public health priority for developed continents like North America and Europe,” Marinero said. “NTDs, as well as Zika, are transmitted by vectors such as mosquitoes and ticks. Climate change and increased travel have led to the steady spread of these types of diseases around the world, increasing the need for better surveillance and detection methods to help prevent outbreaks. “

Current testing methods for neglected tropical diseases are often time-consuming, expensive and complex, Stanciu said. “Laboratory techniques to detect the virus are inefficient and require patients to go to the hospital and wait for a period of time to get results, which is not always feasible in developing countries,” she said. “By the time people realize they need to start monitoring the disease, it is often too late and an outbreak has already occurred. We hope our technology will be the first to detect and monitor the disease so that preventive measures can be taken to avoid or mitigate devastating The impact of the outbreak.”


Stanciu, Marinero, and Kuhn developed an amperometric biosensor utilizing functionalized nanoparticles that specifically bind target viral DNA or RNA. When binding occurs, the device resistance changes, and the sensor uses this change to unequivocally detect the presence of the virus. Sensors can then determine whether and how much virus is present in the blood or mosquito sample. Sensors rely on agents that respond only to the expected virus to be detected.

“We’ve used mosquito samples on our lab-scale sensor, and we’ve been able to detect viruses with high sensitivity to low concentrations of the virus,” Stanciu said. “We’re particularly interested in dengue and Zika because it’s the same mosquito that transmits both diseases, so our technology can quickly detect one of them using the same platform,” says Marinero, who plans to further develop the device’s There are many ways.

“Our overarching goal is to provide an easy-to-use point-of-care, possibly personal device. This will allow people to detect the virus in time without having to go to the hospital, which has major implications for developing countries,” he said. “However, we are also developing an autonomous device that can be deployed in remote field areas that are difficult to access or difficult to detect on-site to monitor outbreaks in these areas.”

The device will operate over a low-power wireless network and will use thin-film rechargeable batteries combined with thin-film photovoltaic cells to provide power and energy to the environment to maintain functionality and performance without human intervention. When disease is detected in mosquito samples, it alerts health control officials about potential threats. Stanciu said they are seeking funding to further develop the technology.

“At this point, we are satisfied that our technology is achieving its goals in the lab, and we are ready to start prototyping. The funding will allow us to develop autonomous capabilities that will allow the device to be deployed remotely,” she said. “As Zika outbreaks and other mosquito-borne viruses become more common, we think building a biosensor platform that uses chips to detect a variety of viruses in a single device could make a real difference in mitigating the spread of these diseases and helping the role of people all over the world.”

Zhong Nanshan’s team announced the pneumonia detection method: IgM detection test paper, constant temperature amplification chip

Recently, at the first multidisciplinary online forum on new coronary pneumonia, Academician Zhong Nanshan and his team shared the latest research results on the diagnosis of new coronary pneumonia: two detection methods for new coronavirus infection, namely rapid immunoglobulin M (IgM) detection. Test paper and constant temperature amplification chip.

Rapid immunoglobulin M (IgM) test strips

It is reported that the principle of the detection is mainly realized by lateral flow immunochromatography. IgM refers to the immunoglobulin M in serum. It is the first immunoglobulin produced by the human body after exposure to the virus. It is an important indicator of acute or recent virus infection. Generally, it occurs on the 7th day of infection or 3-4 days after the onset of the disease. Symptoms can be detected.

The advantages of this test are: 1. The sampling is simple, and only 0.5 ml of blood sample (serum, plasma, and whole blood can be used) can complete the test; 2. The time for antibody detection results is shorter, which greatly improves the detection time. Efficiency; 3. The detection is convenient, and some grassroots hospitals and medical institutions can also conduct the detection.

Constant temperature amplification chip detection method

In contrast, the constant temperature amplification chip detection method can also be used as an important means to identify the current new coronary pneumonia and influenza in addition to the detection of new coronavirus infection.

According to Academician Zhong Nanshan, the test only needs to be completely broken with the buffer, and then loaded. The biggest advantage of the constant temperature amplification chip detection method is that it can detect multiple patients simultaneously, and distinguish the new coronavirus from influenza A and B, as well as other existing viruses, which plays a very important role in the investigation of suspected cases. .

The official version of iOS 13.2 is finally here, let’s see if it’s worth upgrading

Looking forward to, looking forward to, if you read the article published by Mingmei Unlimited yesterday, you should know that Mingmei Unlimited predicted the release time of Apple’s iOS 13.2 official version, and also Very accurate.

This is not just when all Apple users are focusing on the new noise-cancelling version of AirPodsPro, Apple quietly launched the official version of iOS 13.2 system. The new iOS system not only provides support for AirPods Pro, but also adds 59 new Emoji emojis. In the Siri options, the ability to delete Siri and dictation history has been added. At the same time, the iPadOS 13.2 system was also launched simultaneously.

For iPhone 11 users, starting with iOS 13.2, the DeepFusion function will be officially turned on. Deep Fusion is a new image processing system that relies on the A13 bionic neural network engine. Deep Fusion uses advanced machine learning techniques to process photos pixel by pixel to optimize texture, detail and noise reduction in various parts of the photo.

Not only that, iPhone 11 series users can also change the frame rate and resolution when recording video.

At the same time, the new system also fixes and improves the problems in the previous version of the address book, information, search, etc. For users of the iPhone 11 series, due to the addition of the exclusive Deep Fusion function, their camera capabilities have been improved again, and more ideal image effects will be obtained. It can be said that iOS 13.2 is worth updating.

As for battery life, Mingmei Infinite will have to test and use it for a period of time before telling you that, as far as the current usage is concerned, it will not be worse than any previous iOS 13 system. After countless tests and comparisons by Mingmei, in fact, the power consumption of iOS 12 and iOS 13 is almost the same, and it is not as exaggerated as some users say that the power consumption is like running water.

Other fixes are the official update log given by Apple, including fixing the inability to use auto-fill passwords in third-party apps, the keyboard may not be displayed when using “Search”, and the swipe gesture cannot be used to return to the home screen and other related issues. I don’t need to watch the series, so I won’t say much about this.

From now on, iPhone and iPad users can get system push upgrades through OTA.

However, the new system is also accompanied by various bugs. The worst thing is that the HomePod is unusable. According to foreign media reports, a number of Apple users have reported that Apple’s home audio system HomePod became bricked after upgrading to the iOS13 system.

Specifically, the HomePod stopped working, the top flashed a white or red light, and the problem could not be eliminated by restoring the factory settings.

Apple has yet to acknowledge the issue, nor has it provided any official solution. There is also news that Apple wants users to take the faulty HomePod to aftermarket replacement parts.

In addition, there are bugs. The official version of iOS 13.2, as the version with the highest version number, has undoubtedly fewer bugs than the previous version. However, there are still some small bugs, such as some APPs seriously kill the background, and a very small number of APPs still have flashbacks.

Surprisingly, in addition to the official release of Apple’s iOS 13.2, it solved the iPhone X home screen stuck and fixed a lot of problems. Apple also provides synchronous updates for 5S/6, including iPhone 5S, iPhone 6 and other devices, and pushes a new version of iOS firmware.

Of course, the update for these devices is the official version of iOS 12.4.3, and the version is 16G130 for repair only. This update is available for iPhone 5s, iPhone 6, iPhone 6 Plus, iPad Air, iPad mini 2, iPad mini 3, and sixth-generation iPod touch.

In addition, Apple’s emergency push notification shows that the official reminder must be updated to iOS 10.3 before November 3. 4 system, otherwise there may be serious problems that the entire phone cannot access the Internet, including not being able to roam in Safari, send and receive emails, sync iCloud, access the App Store, etc. In fact, iOS 10.3. 4 The intention of the update is to fix every 19. The positioning problem caused by the 4-year GPS time rollover (starting on April 6 this year), but the iPhone 5 is even more special, and it will even involve the normality of the entire machine’s Internet access.

On July 23 this year, Apple officially released the official version update of iOS 12.4, which brings the iPhone migration function, which can directly migrate data from the old iPhone to the new iPhone, while improving the security of the iPhone and iPad.

It is worth mentioning that Apple is developing new smart battery clips for the iPhone 11 and 11 Pro series. Photos of the iPhone 11 series smart battery clips have appeared in the latest iOS 13.2 system, which are divided into three parts. model. It is believed that Apple will soon start selling smart battery clips designed for the iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.

Update suggestion:

This version is a major version update of iOS13, and there are still many small problems. The improvement in fluency is relatively obvious, including the opening speed of the application and the overall animation smoothness, and the unlocking speed has also been improved. However, the problem of killing the background does exist. Although it is not as frequent as the feedback of individual netizens on the Internet, it is recommended for users who are more concerned about killing the background. Wait and see, and wait for the next minor version update.

In addition, iOS 13.2 fixes a number of bugs, which have played a great role in improving system stability. Because the first few official versions of iOS13 performed relatively poorly, for iOS13.2, Apple still recommends users to upgrade. If you have already upgraded to a certain version of iOS, and there are constant problems when using it, Mingmei Infinitely recommends updating. At present, there are fewer and fewer bugs, and the system stability is strengthened. It is still worth updating. As for users who are still in iOS12, you can and many more. What do you think of iOS 13.2? Welcome friends who have upgraded to share their experience.

Finally, what Mingmei wants to say is: Although at this stage for Apple, the sales of the new iPhone 11 series are the main event, but for our majority of fruit fans, the stability of the latest iOS 13 system is the most important thing. the most critical. Of course, many of our fruit fans also sincerely hope that Apple can put some energy into its core “moat” – the iOS ecosystem.

So, if you have anything else to say about the official version of iOS 13.2 that Apple just released today, please leave a message in the comment area and let Mingmei participate in the discussion together!

The funds will be used to pay their rent and meet other basic needs to help the most vulnerable residents during this crisis.

In addition to Silicon Valley, Marvell is looking for similar foundations near other major offices in the U.S., Europe and Asia, and will allocate funds based on need and employee availability. Beneficiaries will receive assistance from food banks, homelessness prevention systems and financial support foundations for those affected by the outbreak. Grants from this fund match 100% of employee contributions to a specific foundation (up to a maximum of $2,500), giving employees the opportunity to support the most impacted populations in their respective communities.

Second Harvest Food Bank in Silicon Valley: In addition to the Community Relief Fund, as nearly 2,000 Marvell employees are now working from home, Marvell will donate monthly employee food to the Second Harvest Food Bank while the Santa Clara employee restaurant is closed $250,000 for groceries. The food bank is one of the largest relief agencies in the nation and works to ensure healthy meals for every member of the local community. Now, Second Harvest Food Bank has seen a five-fold increase in phone inquiries as members of the local community are temporarily laid off, lost hourly jobs, are forced to drain their savings, and face a feeding crisis. Today, to reduce exposure, its warehouses pre-package food, resulting in significantly increased operating costs. In addition, their volunteer ranks have also been affected as the elderly and people with pre-existing health conditions are required to stay at home.

Matt Murphy, CEO of Marvell, said, “As long as employees are working from home, the Santa Clara campus will maintain minimal basic operations. We hope that through strong means, funds can be used to support the local economy, especially now the most Those in need. In the meantime, we will continue to pay full wages to cafeteria staff and support staff, and donate grocery budgets to local almshouses to do our part in the community where we can.”

Purchasing recovery DRAM contract price decline in the fourth quarter has significantly converged

According to the latest survey by DRAMeXchange of TrendForce, the average price of DRAM in the fourth quarter still fell slightly compared with the previous quarter, but the decline has narrowed to about 5%. Compared with the first month of the previous quarter, the transaction volume in October was significantly larger, indicating that the buyer’s willingness to purchase is gradually increasing. Once suppliers’ inventories are reduced, the need for price reductions will drop significantly, which will help DRAM prices stabilize and rebound in 2020.

In response to recent market news that may affect the supply side, such as Samsung’s plan to restart and expand production, and China’s DRAM factory to increase film production in 2020, TrendForce believes that Samsung has no plans to increase film production in the first half of next year. The current capital expenditure plan It is only for the purchase of a new machine, which is used to transfer to the 1Znm process. SK Hynix recently reiterated that it will reduce its capital expenditure for next year, which means that the growth of supply bits next year will be slower than this year. Although Micron semiconductor has not officially announced its capital expenditure plan for next year, it is expected to be more conservative than this year.

In terms of the development of China’s DRAM industry, although Hefei Changxin has announced that it will officially introduce mass production by the end of the year, the initial capacity planning is still very conservative. A period of learning curve will have limited contribution to the growth of the overall DRAM industry’s bit supply in 2020.

The momentum of the spot market has been weak recently, and the price has fallen below this year’s new low

Compared with the contract market, the momentum of the spot market is much weaker. Since the trading volume of the spot market has shrunk significantly, prices are prone to violent fluctuations due to market news, such as the surge in consecutive days caused by the impact of the Japan-South Korea trade war in mid-July. However, after Japan approved and opened the import of chemical raw materials to South Korea, the doubts about DRAM supply disappeared, and the spot price showed a trend of small daily decline. In late October, it fell below the new low before the surge in July.

TrendForce believes that the current spot price trend is still within the expected range. As long as the contract price trend is stable and the demand side has not seen a major downward revision, the weak short-term spot price trend will not affect the overall market conditions in the future.
