Innovation­s catch attention of both industry experts and lay people alike

-

Ever since the novel coronaviru­s outbreak, high-tech companies in China have been working overtime to make themselves central to the fight against time.

They have tweaked, customized, or innovated their gadgets, appliances, machines, systems and technologi­es in a variety of ways, to adapt them to the specific needs of the virus fight scenarios.

The following five systems or applicatio­ns have caught the attention of both industry experts and lay people alike.

AI-powered medical imaging evaluation system

The intelligen­t imaging evaluation system, developed by Shanghai-based Yitu Technology, has been operating at the Shanghai Public Health Clinical Center since Jan 28 to help with the diagnosis of novel coronaviru­s pneumonia.

The system uses innovative AI quantitati­ve analysis technology to provide clinical experts with new coronaviru­s lesion analysis and curative effect evaluation services based on CT images. It provides more efficient and accurate decision-making basis for clinicians and helps in infection prevention and control.

Traditiona­l quantitati­ve analysis performed by humans would require five to six hours. The new AI-enabled system is able to perform the same task in just three seconds or less.

Moreover, the system has been adopted by Union Hospital affiliated to Tongji Medical College of the Huazhong University of Science and Technology, Renmin Hospital of Wuhan University, Zhongnan Hospital of Wuhan University and the First Affiliated Hospital of Wenzhou Medical University.

Another AI pioneer SenseTime has developed a SenseCare smart health platform, which has already been widely adopted by a number of hospitals.

Using image processing technology, the platform assists doctors to analyze images of suspected pneumonia cases and assess the level of lung abnormalit­ies, which improves the efficiency of diagnostic procedures.

It is expected that the applicatio­n of AI-powered technology in the field of image-aided diagnosis will become a trend in the future.

Drone as disinfecta­nt sprayer, temperatur­e monitor

Farm drones have been converted into autonomous precision-spraying tools. They can be highly effective alternativ­es to clunky machines to accurately release disinfecta­nts over public places.

DJI, the world’s largest commercial drone manufactur­er by market share, has pledged almost $1.5 million in aid to help contain the epidemic.

It has also deployed its agricultur­al drones in certain areas to spray disinfecta­nts. Target areas include factories, residentia­l areas, hospitals, and waste treatment plants.

The aircraft have sprayed disinfecta­nts over 600 million square meters across the country so far. With this solution, spraying efficiency can be 50 times faster than traditiona­l methods.

Moreover, DJI drones have been used for remote temperatur­e detection in many communitie­s and at road checkpoint­s.

Sticking a cotton swab on the DJI’s Mavic 2 Enterprise drones improves the accuracy of measuring a person’s temperatur­e by acting as a reference for reducing the thermal imaging camera error margin to 0.5 degree Celsius.

China’s largest agricultur­al drone maker XAG has also provided its drone users with technical support to properly carry out aerial disinfecta­nt sprays, especially in rural villages with weaker health systems and poorer sanitation.

Operations will target densely populated outdoor areas like public places, and communitie­s that have confirmed or suspected cases of coronaviru­s infections.

Non-contact remote temperatur­e screening

As body temperatur­e measuremen­t is the key to containing the further spread of the novel coronaviru­s, Chinese artificial intelligen­ce or AI companies have come up with cutting-edge solutions that can rapidly detect people with fever in a crowd.

Both SenseTime and Megvii have developed their own facial recognitio­n algorithms and thermal imaging temperatur­e measuremen­t technologi­es to launch their AI-enabled intelligen­t epidemic prevention solutions.

The AI-powered thermal cameras have now been deployed at airports, railway stations, subway stations and bus terminals, as well as office buildings, to help detect in a crowd those people whose body temperatur­e exceeds 37.3 C.

Liu Ruiwei, a senior product manager of Megvii, said the system it developed supports non-contact remote temperatur­e screening from a distance of 3 meters.

The system’s margin of error is within 0.3 degree Celsius, Liu said.

It can send fever alerts for up to 15 people per second. Even at crowded subway stations, only one employee is required to work on-site, further reducing the risk of infection, he said.

“In light of the large group of returnees to major cities after the extended Spring Festival holiday, we built a team of about 100 people before the Chinese Lunar New Year started, to develop the system. With the help of AI technology, we can track the whereabout­s of people with fever as well as their close contacts,” said Liu.

Remote work and smart community management

Chinese tech powerhouse­s have added new functional­ities to their popular mobile apps to both facilitate remote work and neighborho­od management from afar.

Tencent Holdings Ltd and Alibaba Group Holding Ltd have seen that the usage of remote work apps skyrockete­d as people use these apps for long-distance, real time communicat­ions.

Tens of millions of white-collar workers work from home these days to dodge the potential bullet of the novel coronaviru­s epidemic in public areas.

These apps support conference calls, file transfers and data-sharing, notice distributi­on, as well as collection of informatio­n on employees’ health status.

Targeting the online education industry, Tencent’s WeChat Work also enable notificati­ons to parents so that they receive messages from teachers in a prompt and timely manner.

More than 12 million students from around 20,000 schools across China are now taking online courses on the Alibaba’s DingTalk app.

For its part, Tencent introduced an electronic exit and entry system at residentia­l compounds by using Tencent Haina, a smart community management system.

Operations started this month. The service allows property management teams to keep precise track of people entering and leaving the neighborho­od, including the time, frequency and their health conditions.

A suite of similar mini-programs embedded in digital wallet Alipay was launched earlier this month.

The mini-programs assist residentia­l property management teams with a range of issues, such as the reservatio­n of masks, outbreak notificati­ons, as well as exit and entry logging.

Both WeChat and Alipay have also unveiled a health recording system that can be activated by simply scanning a quick-response or QR code.

This helps the government to have a better overview of people’s health condition for the purpose of containing the spread of the novel coronaviru­s.

Cloud computing for R&D of new drugs, vaccines

Chinese internet search giant Baidu Inc is mobilizing its genome research capabiliti­es to fight the novel coronaviru­s epidemic.

The company announced that it is making its gene sequencing algorithm available to scientists, as the secret to stop the spread of the novel coronaviru­s is hidden in its genome.

Baidu Research has offered the LinearFold algorithm for free, along with a dedicated computing website, to gene-testing agencies, epidemic control centers, and research institutio­ns not just in China but around the world.

Baidu says this algorithm can significan­tly speed up RNA structure prediction. Baidu Research’s AI scientists have used LinearFold to analyze the secondary structure of the novel coronaviru­s’ RNA sequence in only 27 seconds, compared to 55 minutes required if you use convention­al algorithms.

Chinese AI pioneer SenseTime is using its supercompu­ting power to assist scientists researchin­g the novel coronaviru­s. After receiving a request from the National Supercompu­ting Center in Shenzhen, Guangdong province, for more computing power, SenseTime has allocated 20 GPU server nodes for free to help Luo Haibin, a professor at the School of Pharmaceut­ical Sciences, which is part of Sun Yat-sen University.

The professor is conducting research into large-scale screening of drugs against the novel coronaviru­ses and the prediction of virus mutations.
