| According to the British "Daily Mail" report on December 8, a technology called "backscattering" will soon be launched, which uses low-power radio signals already in the environment to send information, which can transform random objects into For the radio station, and send information to the mobile phone. With this technology, everyday objects around us can "communicate" with people. |
American University develops "backscattering" technology that consumes almost zero electricity
Using backscattering technology, a research team at the University of Washington in the United States has successfully developed a "singing poster" that can transmit the band's music to a smartphone from 12 feet (4 meters) away, and 60 feet (18 meters) away. ), transfer it to the car.
The researchers say they have also developed a T-shirt that can "talk" to people. Using conductive thread to sew the antenna into the T-shirt, using the surrounding radio signal to transmit data to the smartphone at a speed of 3.2 bits per second, the T-shirt can record and send information about the vital signs of the runner.
Researchers hope the new technology could help develop "smart cities". "What we're trying to do is make any everyday object in a smart city—posters, road signs, even clothes—send information to people's phones or cars, so that they can communicate with people," said Siam, an assistant professor in the Department of Computer Science and Engineering at the University of Washington. say."
Academician of the Academy of Engineering: There is no need to install Wi-Fi on the high-speed rail, the scenery is very good
In recent years, the rapid development of high-speed rail projects has brought great convenience to people's travel. At the same time, the call for high-speed rail to be equipped with Wi-Fi has not diminished. In this regard, Wang Mengshu, an academician of the Chinese Academy of Engineering and deputy chief engineer of China Railway Tunnel Group, said in an interview with domestic media on the 5th that high-speed rail Wi-Fi will affect locomotive signals, communication signals, and mobile Internet access will also have a great impact.
Now some high-speed trains of railway bureaus are equipped with Wi-Fi. After trying it, the cost is very high, and it will break down after a short time. So it is still not installed. Everyone, take a good look at the beautiful scenery on both sides, what are you doing with that (Wi-Fi). And there's no need for that, young people are all bowing their heads, and they still bow their heads on the high-speed rail?
Wang Mengshu explained as above.
Google internet hot air balloon crashes in Amazon forest
According to the British "Daily Mail" report, a hot air balloon developed by Google to provide Internet to remote areas crashed in the Amazon forest. For this "accidental fall", Google has apologized to the Amazon region in northern Brazil.
The wireless hot air balloon dropped 11 miles (17,700 meters) above a remote town in Brazil. Google stated that it has reported the accident to the Air Traffic Administration, and relevant experts have gone to the area to clean up the hot air balloons in order to further understand the relevant flight principles.
Previously, Google has launched the "Project Loon" project, using hot air balloons to provide Internet to remote areas around the world. The hot air balloon is 15 meters in diameter and is made of thin, biodegradable plastic. "After research and several routine flight tests, we worked with the Air Traffic Authority to reduce the speed of the balloon if it was safe to do so," a Google spokesman said. Two cities in northern Brazil were chosen for the mission in 2014. project test area.
Toyota launches second-generation self-driving prototype: equipped with 7 lidars
The Toyota Research Institute (TRI) in California recently demonstrated a version 2.0 self-driving car to the outside world.
This is the first autonomous driving test platform fully self-developed by TRI, and its purpose is to help research groups test and explore vehicle safety features and autonomous driving technologies.
Specifically, the roof is equipped with a Velodyne 64-line lidar, and six 16-line lidars are distributed on the front and roof of the car. There are ordinary radar and GPS antennas on the front, rear, left and right sides of the roof, and finally three left and right sides of the front. Camera. Combined, the sensors cost more than $120,000.
The government work report first mentions that the fifth-generation communication manufacturers seize the industry's first opportunities
On the morning of March 5th, the fifth meeting of the Twelfth National People's Congress opened. Premier Li Keqiang mentioned in the government work report: "Accelerate the cultivation and growth of emerging industries. Fully implement the development plan for strategic emerging industries and accelerate the development of new materials. , artificial intelligence, integrated circuits, biopharmaceuticals, fifth-generation mobile communications and other technology research and development and transformation, and make industrial clusters bigger and stronger.”
This is the first time that "fifth-generation mobile communication technology (5G)" is mentioned in the government work report, which means that the previous investment has been affirmed for the communication equipment manufacturers, terminal operators and operators who have already participated in the 5G industry chain. Meaning the outlook is clearer.
Communications expert Xiang Ligang (Weibo) told the reporter of "Daily Economic News": "The current industry has a grand industrial blueprint for 5G networks to transform traditional manufacturing industries and support new technologies. China's 5G industry deployment will go ahead. At the top of the world."
There are more and more connected devices in hospitals, but security issues have not attracted enough attention
According to a study by IoT security company Zingbox, the average hospital bed in the US has 10 to 15 connected devices per bed. “We often think of the healthcare sector as being very conservative and slow to embrace new technology due to various regulations and responsibilities, however, IoT devices are increasingly being seen in hospitals due to the enormous benefits that connected devices bring gone."
"Over the past three years, the medical sector has been hacked even more than the financial sector, and more and more attacks are targeting medical devices," May Wang, Zingbox's chief technology officer, told Wired.
Computers and servers often run antivirus and other security software, while IoT devices often lack the necessary security measures. Cybersecurity firm TrapX has seen hackers implant malware into medical devices to steal medical information. In this way, hackers can steal personal identities, buy drugs online and sell them on the dark web. This attack method is named MedJack (Medical Device Hijacking).
At present, the safety issue of medical equipment has attracted the attention of FDA (US Food and Drug Administration). Before approving products for marketing, the FDA regards cybersecurity as an important consideration and gives corresponding guidance.
The Industrial Internet Consortium Releases Version 1.8 Reference Architecture to Help Enterprises Start IIoT
The Industrial Internet Consortium (IIC), established to promote the accelerated growth of the Industrial Internet of Things (IIoT), recently released version 1.8 of the Industrial Internet Reference Architecture (IIRA). Based on the version 1.7 released on June 17, 2015, the latest Internet of Things (IoT) technologies, concepts and applications are added.
The core concepts of Industrial Internet of Things, and the technologies mentioned in IIRA version 1.8, can basically be applied to manufacturing, mining, transportation, energy, agriculture, medical, public infrastructure, and all other industries Among them are large, medium and small enterprises.
In addition to industrial IoT system architects, the concept of integrating operational technology (OT) and information technology (IT) emphasized in IIRA version 1.8 can also make business decision makers, factory managers and IT managers more clear Learn how to advance Industrial IoT systems from an enterprise perspective.
