Samsung launched the world’s smallest camera sensor (Image: The Verge) Recently, Samsung has launched a new camera sensor for smartphones, with the smallest pixel size in the world. ISOCELL JN1 is a 50MP sensor, 1/2.76 inch size is relatively small, pixel size is only 0.64 μm. Camera experts often say that the smaller the pixel size, the worse the image quality and the higher the noise. So why does Samsung continuously release sensors with such small pixel sizes? According to Samsung, the small camera sensor can still ensure the resolution of the photo. The smaller sensor size makes it easier to design telephoto and ultra-wide-angle camera modules, as the lens structures of these cameras are more complex than conventional cameras. That means the camera will be less convex. Like many cameras the sensor can capture images at 12.5MP resolution, which equates to a pixel size of 1.28 μm. Samsung also integrates ISOCELL 2.0 technology, which increases light sensitivity by 16%. Samsung says the JN1 is currently in mass production, so it is likely to appear on Samsung smartphones in the near future.

Explaining the mechanism of action of this method, Mr. Quang said, test participants will be gargling with salt water. This solution is then put into a test tube and placed in the test device. If in other methods, the time to return the results will take from half an hour to several hours. Meanwhile, with this method, it only takes 10 seconds to produce results, Mr. Quang shared. Bkav CEO Nguyen Tu Quang. Photo: Trong Dat To do this, Bkav uses a frequency band of light shining into the test tube containing the patient’s saline solution, which is collected by the sensor at the output. Bkav’s artificial intelligence technology will help measure how much frequency is absorbed. Different frequencies of absorption produce different types of disease, in this case Covid-19. Mr. Quang said: “The naked eye can’t recognize the difference of those absorption frequencies. We have to train the AI ​​to know which is the specimen of the Covid patient and which is the human sample. not infected with Covid-19”. According to Quang, Bkav’s method of testing for Covid-19 with saline mouthwash solution will give faster results than conventional methods. The founder of Bkav company said that compared to the method of testing Covid-19 by breath, the salt water test technology is simpler, with the investment money for a testing unit much cheaper, even almost no cost. This test method has been tested by Bkav since the end of 2020 at the Central Hospital for Tropical Diseases. “Initial results were recorded as positive with a recognition rate of over 90%,” Mr. Quang said. According to CEO of Bkav, this business is the second company in the world to develop saline testing technology. Previously, a company in Israel had developed this technology.

According to the research team, the new shirt product will help monitor the function of people’s hearts when they participate in activities such as jogging. The sensor is a self-powered device that can detect the wearer’s electrocardiogram, in other words, it will measure the action potential of the heart. In addition to finding ways to make smart devices attached to clothes (including shirts) more comfortable, researchers are also looking at deploying smart devices. into textiles to perform functions such as measurement, energy capture and energy storage. “We leveraged different processes and designs from the nanoscale to the macroscale to see if we could integrate electrical devices,” said Braden Li, a PhD student in the research team. death in textiles or not”. Illustration The shirt with the sensor is actually a project that Braden Li is overseeing. Specifically, the sensor is a low-power self-powered device that can sense a person’s electrocardiogram, which means it measures the electrical potential of the heart. For this project, NEXT is working with Advanced Integrated Sensor and Technology Systems (ASSIST) in NC State, as well as collaborators at Penn State who are building a shirt supercapacitor. However, it’s not as easy as creating a mere wearable that monitors heart activity. “You get all the different wishes and requirements on this smart product. Now you need to link them up on this shirt and make sure it looks good and is washable. You have to make sure it’s comfortable to wear. But that comfort is not suitable for a sensor to work normally; because the device also needs to be stable, it can be difficult to keep balance when mounted on a fashion product,” said Braden Li about the challenges of the research. Marissa Noon, a third-year student studying textile engineering, adds: “Having really smart fabrics is great, but they’re really hard to come by in the real world. It may be uncomfortable for the wearer to wear such fabrics, or the built-in smart devices may not last long… So it’s really important to have a soft fabric so you can stay comfortable. move freely but it still measures accurately.” It is known that the smart shirt product is not the only project that the team is working on. Researchers have developed a smart sock that can reduce the recovery time of a sprained ankle from four to six weeks to two to three weeks, while users can still do it. some movement during the recovery period. “The research and work being done at NEXT is exciting, and the team’s researchers are using their endless creativity to combine technology with art to create unique outfits. thoughtful, useful and comfortable in the future. Keep an eye on our research, because, one day, you may soon find Nike or Adidas products using generations of NEXT devices,” the team wrote. hope.

The three new Bugatti smartwatches bear the names of several of the luxury automaker’s brands – such as the Bugatti Pur Sport, Le Noire and Divo. These three models all have the prefix Bugatti Ceramic. All three smartwatches pack an impressive number of features and functions including up to 90 different sport modes, health and fitness sensors that help track key stats at all times, as well as GPS. Heart sensor with two purposes of measuring both heart rate and heart rate variability. Three Bugatti smartwatches crafted with the highest precision, class and comfort.

Photo: CNET Apple first introduced optical image stabilization through sensor movement for the wide-angle lens on the iPhone 12 Pro Max. This technology stabilizes the camera sensor instead of the lens to provide better stabilization and higher image quality. Photo: CNET “Up until now, optical image stabilization via motion sensor was only available on professional DSLR cameras,” Apple writes on its website. “This is the first time they have been tweaked for the iPhone. Whether you’re shooting kids chasing them in the park or you’re shooting video through your car window on a bumpy road, you’ll have better stabilization than ever before.” Photo: CNET iPhone 13 is expected to have a larger rear camera cluster than the current design, most likely to accommodate a larger sensor and other upgrades.

Apple has rearranged the selfie camera, speakerphone, front camera, TrueDepth camera to be placed closer together, in which the speakerphone is moved to the top instead of in the middle of the TrueDepth camera system as before. Apple is also looking to source VCSEL chips with sizes 40-50% smaller than those used on older iPhone generations. This chip is used for 3D face recognition for iPhone 2021. This allows Apple to shrink the size of the Face ID sensor cluster. Leaked design image of iPhone 13. In addition, the size of the rear camera cluster on the iPhone 13 Pro will increase because of the integration of a new sensor. If this is correct, the performance of the camera on the iPhone 13 Pro will increase significantly compared to its predecessor. Earlier, a rumor also suggested that the iPhone 13 versions will be about 0.17 mm thicker than the current iPhone 12. With a thicker size, Apple will equip the iPhone 13 with a larger battery. This is necessary as the iPhone 13 is also expected to use an LTPO panel with a 120Hz refresh rate that consumes more power than the iPhone 12 screen. One rumor also claims that the iPhone 13 Pro will have a 1TB capacity version. With this capacity, users no longer worry about memory storage. And of course, the price of the 1TB capacity version is not cheap either.

Xiaomi Redmi Note 8 2021. Thanks to the nano coating, the Xiaomi Redmi Note 8 2021 is slightly water resistant. 4,000 mAh battery capacity, integrated fast charging with 18W output. According to the manufacturer, Redmi Note 8 2021 takes 2 hours to fully charge.

The images on the patent show a phone with a triple camera module at the back, with the top camera able to rotate between front and back positions. When in selfie mode, the camera will turn inward and the display area around the camera will be disabled so that light can reach the sensor. A magnetic or mechanical mechanism will help rotate the camera. Realme launched a smartphone with 5,000 mAh battery, 33W charging, 90Hz screen, 6 GB RAM, priced at more than 4 million VND This design will bring a number of advantages over the product. The first thing to know is that it will enhance the quality of selfies. The selfie camera is rarely on par with the rear camera when it comes to imaging performance, not to mention that the under-display camera can be at an even greater disadvantage than the traditional selfie camera. By rotating the main camera from the rear module, Xiaomi can improve the performance of the selfie camera without paying extra for a better selfie camera. Taking advantage of the rear camera not only saves money on buying a high-end camera sensor, but it can also help utilize the space inside to increase battery capacity. Waterproof smartphone, S888 chip, 12 GB RAM, 240Hz screen, 2,000 nits brightness However, it also leads to a few downsides. A rotating camera will also need additional components for it to rotate, so it will lead to a waste of battery space. Rotating the lens inside the phone can have an additional side effect that the camera part may have to be even thicker to be able to rotate the lens – which was already thick. Detailed photos of Asus ZenFone 8 Flip: ‘super terrible’ configuration, 5,000 mAh battery, 90Hz screen, rotating camera, priced at more than 22 million Xiaomi’s invention idea. Finally, some glitches with the rotating camera can also occur. A flip camera with moving parts can always be damaged and that is the main concern when sliding camera systems in the past have always had certain problems. As everything happens inside the phone, it means that if there is debris happening inside the mechanism, it will force deep intervention into the hardware. See the waterproof smartphone, the world’s best screen, S888 chip, 12 GB RAM, ‘super big’ camera Like other patented technologies, it is unclear if Xiaomi will put this technology into actual products. In fact, Apple has also researched a mirror system that illuminates from the front and rear cameras into the same sensor through a patent in 2015, but this mechanism has not been implemented by Apple so far. on its products.

Users can now use old Samsung Galaxy phones as smarthome devices. Current functions include: Using an improved artificial intelligence (AI) solution, Galaxy devices can more accurately distinguish sounds in everyday surroundings, and users can choose to save certain recordings. . For example, if the device detects sounds like a baby crying, barking dogs, cats hum or knocking on the door, it will send an alert directly to the user’s smartphone and the user can hear the recorded sound again. Devices can also be used as a light sensor to measure the level of the room’s brightness. Users can easily set the device to automatically turn on the lights or the TV through SmartThings if the room becomes darker than the preset lighting standard. To use an old Samsung device as a smarthome sensor, make sure that the user is running the most up-to-date version of the SmartThings app from Samsung. The user will also need one of the smartphones as shown in the list of images below. List of Samsung devices that support Galaxy Upcycling. After making sure this, launch SmartThings, then tap the three-line icon in the middle left, tap SmartApps, then tap the three-dot icon in the middle right. Tap SmartThings Labs, then tap Galaxy Upcycle to start the installation process. After installing the Galaxy Upcycle app, users launch it and choose a sensor type. At this point, the user will be asked to choose a location and room where the device will be. These should match up with anything the user previously set up in the Samsung SmartThings app. Done, the user should now see their sensor online and up and running. Finally, plug in the phone, turn off the screen and let the sensor work. Users may need to visit the SmartThings app again and set up automation that uses new sensor data to perform an action, such as automatically turning on the lights in a room when the general environment is too dim.

Recently, billionaire Bill Gates and his wife – Melinda Gates announced on Twitter that they will divorce after 27 years of marriage. According to Forbes, Bill Gates is currently the 4th richest person in the world with a net worth of $ 130.5 billion. Bill Gates and his wife have many real estate properties, including a 6,100 square meter mansion in Washington. Bill Gates’ mansion was built in 7 years and cost 63 million USD. Before that, Bill Gates bought this land for $ 2 million in 1988. Located on a hillside surrounded by tall trees, the villa is covered with greenery with lots of plants. The work was first completed in 1992 with a 170-square-meter guest house area. This guest house has one bedroom, one bathroom. These are the first places where the technology is tested for future use in the main building. Nearly 500,000 trees were used to build this house, including 500-year-old fir trees. There is also an artificial stream next to the villa for fish release. The villa area has 24 bathrooms, 10 of which are fully equipped with amenities. Bill Gate’s garage can accommodate 23 vehicles, distributed in various areas around the building. In addition, the Bill Gates mansion also has a total of 6 kitchens, located in different places and the staff can be ready for any event, any time. The entire villa is installed with high-tech sensors to monitor the climate and light. Upon arrival at the house, guests are given a panel that interacts with sensors installed throughout the house. They can go to temperature and light to adjust according to their preferences. The wall-mounted speaker system plays music with every step through the rooms. Even the path to the house is also heated. The cinema room is nearly 140 m2, extremely spacious and comfortable for 20 guests. There is also a popcorn machine with a choice of corn and butter. The 18-meter-deep swimming pool is located in a private building of more than 360 square meters. The swimming pool is also equipped with an underwater music sound system. Photo source: BI.

Uran-9 combat robot is 5.12m long, 2.53m wide, 2.5m high, with a total combat weight of 12 tons, is the most typical heavy fighting robot among many ground combat robots of the Russian army . Russian Uran-9 combat robot. Source: people.com.cn. The robot is equipped with various sensor modules including laser sensor, photoelectric sensor and thermal image sensor. It is capable of automatic target recognition and tracking. It can detect and track targets to a range of 3,000 meters and maneuver in either remote or automatic mode. The maximum road maneuver speed is 35 km / h and the continuous combat time is 6 hours. The robot is equipped with 1 30mm 2A72 cannon, 4 9M120 Ataka anti-tank guided missile launchers, or 6 RPO Shmel 93mm thermo-missile launchers and 1 PKT / PKTM machine gun. At the same time, the robot can also carry 9K38 surface-to-air missiles, 9K333 mobile air defense missiles and 9M133M anti-tank missiles depending on mission requirements. It can be said that robots can create “fatal” attacks against armored targets, low-range targets and infantry forces. Looking at the development and application of weapons and smart equipment of the Russian Army, it can be seen that Russia has embarked on a path of developing military equipment integrating artificial intelligence different from the West. . Especially from the development and application of the Uran-9 combat robot, three characteristics can be seen in the intelligent military development of the Russian Army. The first is to focus on the real warfare of smart technology. Compared with the West’s search for advanced intelligent technologies, the Russian Army places more emphasis on improving its practical combat capabilities. For example, the Uran-9 combat robot is strong enough to take on an armored infantry team. Heavy armored vehicles can cope with attacks from general infantry weapons and crawler chassis can adapt to complex terrain such as hills and mountains. Especially in the actual combat test in Syria, the Uran-9 combat robot has shown a high level of attack, defense and maneuverability, which can meet the actual combat needs of the ground forces. Russian troops in such missions as fire suppression, fire suppression and infiltration of enemy front lines. In general, the results achieved by the Uran-9 combat robot are due to a design philosophy that meets the practical combat needs. Second, improve the level of intelligence based on the advantages of motorized equipment. The Russian military has always had a strongly mechanized armed force, but its intelligence still has a certain distance from the West. To quickly close this gap, the Russian Army has chosen to push the development of intelligent military equipment in the direction of modularization. The Uranus-9 combat robot’s armor, weapons and chassis are the products of the era of mechanization, while sensors, fire control systems and automated algorithms are products of the age of intelligence. . Through the combination of these two methods, Russian combat robots can quickly adapt to the battlefield in the future. Based on this method of combining traditional equipment with this advanced technology, the Russian military is developing smarter weapons and equipment. Third, to address the shortcomings of conventional forces to develop intelligent weapons and equipment. Under Western containment, it was difficult for the Russian Army to develop conventional weapons and equipment on a large scale and expand its military might. In the face of NATO’s increasingly intense military pressure, Russia needed to compensate for the shortcomings of conventional military might in a manner consistent with its economic requirements. In terms of military might, the newly formed Uran-9 combat robot unit can be said to fulfill this requirement completely. Compared to the involvement of an armored infantry army, the military costs and the risk of the robot unit’s casualties are much lower on the battlefield, which is one of the key reasons why the Russian Army plans to increase. The proportion of unmanned weapons and equipment in the military by 2025 is 30%.

An old Galaxy phone is used as a sensor for the sound of a baby crying. Photo: Samsung Through the SmartThings app, users can convert the function of Samsung Galaxy phones from 2018 and earlier into sound sensors to notify when they hear a knock on the door or the sound of a baby crying. Light sensors, which are used to adjust screen brightness, can be used to automatically control indoor lighting. Samsung also said that the battery of the old phone will be optimized to increase the uptime when the device has a new “life”. Innovative reuse is a method of reducing technology waste that is still relatively new compared to traditional ways such as giving away, returning the company or reselling. With this project, technology brands from Korea are expected to contribute to encouraging users to take advantage of old smartphones in everyday life, and help promote more of its technology ecosystem. Even so, according to technology site Ars Technica, despite its good environmentalism, the Upcycle program only allows the reuse of light and sound sensors. In fact, spontaneously, users have been devising many initiatives to reuse old phones, such as converting them into security cameras, data storage hard drives or music players.

Galaxy Upcycling at Home’s initiative Samsung was announced at the World Consumer Electronics Show 2021 (CES 2021) earlier this year and is now being tested in beta in several markets such as the US, UK and South Korea. This feature can alert you to the sounds of crying babies or turn on the lights when the light levels drop In this beta, Samsung will allow users to turn old phones into smart home devices that work through Samsung’s SmartThings app, which has two new modes: sound sensor and light sensor. Owners of certain smartphones can download the update to turn the device into a smart home sensor with some functions such as being able to detect the sound of a crying baby or turn on the light when it’s dark. The program is limited to certain smartphones released in 2018 or later. While it’s only recently applied to a few smartphones, it’s a good, accessible service that can help users make use of their old devices. Samsung says the sound sensor mode will help to accurately distinguish sounds in everyday surroundings, and users can choose to save certain recordings. For example, if the device detects sounds such as a baby crying, dog barking, cat sounding, or knocking on the door, it will send an alert directly to the user’s smartphone and the user can hear the sound. Be recorded. Whereas the light sensing mode simply turns your phone into a light sensor, allowing it to detect the level of sunlight or room light to automatically turn on the lights. Samsung says this update includes battery optimization needed to keep the phone powered up and acting as a sensor for long periods of time, though the company didn’t indicate uptime. between charges. Samsung says the “Galaxy Upcycling at Home” feature is available on all S, Note and Z series released in 2018 (S9, Note9 and above) running Android 9 or higher and will be available in the future. More smartphones are supported. Samsung’s upgrade program marks a very humble starting point, and the company can do more if it wants to limit e-waste and make old devices useful. So far, the program has only used microphones and light sensors on older devices. Hopefully in the future, Samsung will take advantage of the cameras of old smartphones to turn old smartphones into IP cameras. Phan Van Hoa (According to Arstechnica, Theverge)

Samsung has an unexpected move Photo: @Pixabay. It seems that the company has realized that “quantity is not equal to quality” should decide to slow down with the megapixel race. Recently, famous leaker Ice Universe announced that Samsung now intends to return to another “rationality”, and will stop blindly chasing big numbers. Clearly, we’re talking about the fact that the company is recklessly stopping the megapixel-resolution race. “I heard some news that Samsung smartphones are actively changing the camera sensor. It will return to reasonable, instead of blindly large numbers,” Ice Universe stated. In fact, Samsung admits that quality is not at the megapixel count. Priorities will be the tradeoff between the size and resolution of each pixel. And the first result of this approach that we saw in the Samsung ISOCELL GN2 sensor; in which the company offers a record large sensor size of 1 / 1.12 inch; No frills on the megapixel count with just 50 megapixels. Photo: @Pixabay. After the shocking information above, it is still unclear what the fate of the 200 megapixel sensor on a smartphone with up to 6 cameras, with a dual selfie camera and a homegrown chip will be. On the other hand, there are also rumors that, Samsung has set itself a goal of delivering an insane 600MP sensor. The 600 MP sensor that Samsung has developed seems to have a pixel density of 0.8 µm and a size of about 1 / 0.57 inches. So the result is more work the company has to deal with as the sensor will take up 12% of the smartphone’s area, and it will also result in a 22mm protrusion. The Galaxy Note20 is 8.3 mm thick, which means the 22 mm camera bump will make the phone look too out of date. Photo: @Pixabay. With these changing priorities, it remains to be seen whether this will affect the development of the aforementioned sensors in the near term. In July 2019, CEO of Zeiss, Mr. Michael Kaschke made the point that, the race of “dots” on smartphones is meaningless. Because according to him, “the sensor on a smartphone is so small that mobile photography will never be able to overcome some of the limits such as processing speed, signal ratio, noise … and increasing the number of” dots. “Not the right solution in this regard, even a stumbling block”. In fact, the higher the resolution of the sensor, the smaller the individual pixels, and the more difficult it is to illuminate them entirely. The result is that the image will be noisy, which the algorithms must try to limit to reduce this situation. For Kaschke, a 40 MP sensor is more than enough for a smartphone, let alone 64 MP. Therefore, increasing the number of “dots” will not bring any benefit. Photo: @Pixabay. However, it is undeniable that the introduction of the smartphone is one of the most remarkable strides in the history of the technology industry. It is not simply a pocket communication device but gradually meets all human information needs. Photography is also an equally important part. It creates many new needs such as sharing daily photos, taking selfies, video calling. Smartphone photography is gradually asserting itself with a steady decline in sales of travel cameras. According to data from GfK, Canon’s travel camera revenue is down 2% per year due to the replacement of smartphones.

YouTube channel owner EverythingApplePro also said that the back of the iPhone 13 Pro Max will remain the same design as the iPhone 12 Pro Max.
