According to DigiTimes, Apple has been increasing the pressure on suppliers for camera lens components. This causes orders to be expected to outpace the entire Android market. (Photo: DrTech / YouTube) Apple is said to have informed the companies responsible for the production of voice coil motors (VCMs – Voice Coil Motor) to increase their capacity. According to the report, Apple has asked related component suppliers to increase capacity by 30-40% to meet their demand. (Photo: EverythingApplePro) Sources have told DigiTimes that there will be significant upgrades in the iPhone 13’s photography technology, including Face ID’s 3D sensor and camera modules. At the same time, demand from Android manufacturers is said to have decreased, especially as US sanctions are still being applied to Huawei devices, also helping the new generation of iPhones benefit in terms of power. supply VCM components. (Photo: Apple Tomorrow / Twitter) For those who don’t know, VCM is an important component used in sensor focus setup. It is expected that shipments for iPhone will surpass in the second half of the year, as all new iPhones will be equipped with sensor anti-shake technology – which was only available on the iPhone 12 Pro Max version released last year. (Photo: AppleTrack) Recently, a report from Wedbush analyst Daniel Ives also suggested that all iPhone 13 models will have LiDAR sensors on the back, including standard non-Pro versions like the iPhone 12 Pro and iPhone 12 series. Pro Max last year.

The disinfection robot combines two methods of UVC and chemical disinfection to help kill bacteria and reduce the spread of disease. The robot also has the ability to move flexibly, remotely or pre-programmed for a certain sterilization route. Le Anh Son, Deputy Director of Phenikaa Institute of Research and Technology (Phenikaa University), said that the robot is also capable of taking on tasks to support epidemic prevention and control in Bac Giang such as: Transporting necessities , monitoring sick and isolated people through monitoring cameras. Phenikaa University’s disinfection robot. The robot is fully self-propelled, avoiding collisions by using LiDAR technology, integrating artificial intelligence to recognize and remind people to wear masks, measure body temperature and a host of other superior features. . On the evening of June 2, the robot was put into operation for the first time. Before that, in the middle of May 2021 when the epidemic was complicated, students of Phenikaa University launched the campaign “Online learning – Show talent against the epidemic”. The students spent time and effort to create a droplet shield for medical staff, medical staff at hospitals, treatment facilities, and concentrated isolation. Up to this point, 10,000 droplet shields have been sent to more than 30 localities, of which more than half have been transferred to the epidemic center Bac Ninh, Bac Giang. High-tech products “make in Vietnam” such as: COVID-19 epidemiological information maps, disinfection robots, self-propelled robots, smart school solutions … or simply splash shields, orezol water These are all feelings of love and sharing from the collective staff, lecturers, scientists and students of Phenikaa University sent to the epidemic center.

In addition, Phenikaa University also donated 10,000 bottles of Orezol water to the frontline medical staff in the fight against the epidemic.

Tesla ditches radar sensors on self-driving systems. Photo: Getty Images No company in the auto industry can attract as much attention as Tesla, on the one hand because of CEO Elon Musk’s controversial statements, on the other hand, because Tesla regularly makes “unusual” decisions. “. At the end of May, Tesla once again became the focus of public opinion, and this time not because of a “brake failure”, but a configuration change. Recently, Tesla announced that starting in May, Model 3 and Model Y in North America will no longer be equipped with sensor radar, cancel the millimeter wave radar in front of the vehicle and only use the camera as a receiver. data collection of automatic driving systems. This means that Tesla is poised to be the first car company to deploy a “pure vision” autonomous driving solution. Meanwhile, other self-driving car manufacturers are integrating radar, LiDAR and cameras in autonomous driving systems. In fact, Tesla CEO Elon Musk has always been adamant against LiDAR, even repeatedly criticizing LiDAR in public. He thinks this is an expensive, unnecessary technology. Even Elon Musk has called those who believe in LiDAR technology “stupid” and car manufacturers using LiDAR technology will never achieve success. So, why is Musk so adamantly “disliked” LiDAR and even all radars, and only favors a camera technology solution? To clear this up, we may need a basic understanding of autopilot schematics. Camera and LiDAR To build a set of automated driving system solutions, the automatic driving algorithm is of course inseparable. In order to achieve calculations, sufficient information is required first. During driving, the vehicle’s information collection source is the large and small sensors on the body of the vehicle. Among them, to realize autonomous driving, the most important sensors are the camera and LiDAR (must add millimeter wave radar and ultrasonic sensor, of course). Therefore, the autonomous driving system is divided into camera-based vision array and LiDAR array. “Camera-based vision” uses a high-definition camera incorporating an image recognition algorithm, while LiDAR to ensure system stability. The camera array, or pure visual diagram, is essentially a complete simulation of the state of a person driving a car, first seeing the image with the “eye (camera)”, then transmitting it to the “brain (processor)” for processing and judgment, and then give the action “Legs (steering mechanism)”. In addition to Tesla, Chinese companies including Jikrypton and Baidu have also adopted pure vision solutions. LiDAR technology uses a laser to measure distances and build a 3D map of an object, by emitting and receiving the laser’s feedback and then analyzing that data to produce the desired results. Many Chinese car companies including Xiaopeng, Weilai, BAIC ARCFOX, and many other new products also announced this solution. Which solution is better? The advantage of the “pure vision” solution is that the video data captured by the camera is the closest to the real world perceived by the human eye, and also the closest to the form of human driving. At the same time, with LiDAR prices currently very high, a pure vision solution using only the camera should be easier to control costs. Tesla’s pure vision algorithm analysis is already very strong. In addition, the image obtained by the camera is well suited for object identification and classification, in case the algorithms are excellent, it can remove confounding items and enable automatic learning during driving. car. However, as a visual algorithm similar to the human eye, the camera is easily affected by light, in harsh weather or poor lighting conditions, it is easy to cause misjudgment. Previously, when AutoPilot was turned on, Tesla models accidentally braked automatically when going over an overpass or under a normal bridge, due to the algorithm using a sudden ball in the camera as an obstacle. Rendering a 3D environment map drawn by LiDAR Compared with pure vision solution, the advantages of LiDAR solution are longer monitoring distance, higher accuracy, more sensitive response speed and unaffected by ambient light. LiDAR’s three-dimensional information processing, object size calculation, and movement speed are more efficient. However, LiDAR has problems such as weak object recognition, high cost, and accuracy in extreme weather conditions such as rain and snow. Therefore, LiDAR must be used in conjunction with other sensors to ensure safe driving. In addition, the collection of large amounts of data requires high computing power of the processor, which equates to an increase in the cost of the media processor. Theoretically, the combination of camera-based vision and LiDAR is a relatively complete solution today, but after combining many factors such as existing technology and product cost, it is too difficult to use. use a “third solution” that integrates these two major solutions. Tesla’s trade-off The cost of LiDAR is much higher than high quality cameras. In fact, abandoning LiDAR, and even now abandoning millimeter wave radar, one of the key reasons Tesla made such a choice was to achieve lower costs. After all, the cost of LiDAR is very high, the price of this technology in the early days started at 100,000 USD, but now with the development of the electronics industry, its price has decreased but basically remains the same. maintained at several tens of thousands of dollars. However, compared to high-definition cameras, the price of only a few hundred dollars is still much higher. However, besides cost, Tesla also has technical trade-offs. First of all, LiDAR does not determine the specific nature of the object, so it is easy to cause wrong judgment. For example, if a large plastic bag appears in front of the vehicle, the camera solution may recognize it as a plastic bag and ignore it, but LiDAR will judge it as an obstruction and stop the vehicle. Second, millimeter wave radar also has many limitations. The detection range of millimeter wave radar is directly limited if the band is weak. It cannot identify pedestrians nor accurately model all surrounding obstacles. At the same time, due to the large amount of data obtained, it will also consume precious computing power of the processor. Finally, for Tesla, the best company in imaging solutions, they have invested heavily in imaging algorithms. To give up the large accumulation so far, and turn to another path, in terms of input – output ratio, it can be said that it is not worth it. Tesla is loyal to a completely camera-based vision solution Tesla Vsion camera system. On Tesla’s official North American website, during the introduction of Full Self-Driving FSD, the performance information of the millimeter wave radar was removed and only the image sensor and ultrasound. At the same time, Tesla also released the driver monitoring system on May 28. The Model 3 and Model Y vehicle cameras can monitor the driver’s behavior when the Autopilot system is activated, detecting and reminding the driver to keep his or her attention. Tesla states that “camera data will be stored in the vehicle, and the system will not send the data back to the company unless the user gives permission to share the data”. In addition, Tesla’s FSD V9.0 autopilot system will also be officially launched this year. According to Musk’s earlier statement, the FSD algorithm has been “refactored” to achieve pure vision through 8 cameras around the body, while effectively solving the previous “brake failure” problem. Tesla also warned that Autopilot and FSD systems would be less effective during this technical adjustment period. “During a short period of transition, Tesla Vision vehicles may experience some limitations or inactivity, such as Autosteer being limited to a top speed of 120.7 km/h. , Smart Summon (if equipped) and Emergency Lane Avoidance may be disabled during delivery,” Tesla’s announcement reads. Whether LiDAR will win the market with a secure advantage in the future, or a camera-based vision algorithm dominates the market with a lower cost advantage, the answer is still unclear. However, judging from the information currently available, Tesla will choose to stick with a pure vision solution.

Last year, the iPhone 12 was officially on the shelves a while ago and is considered a symbol of class and luxury. However, just a few more months, the new generation of iPhone – expected to be called iPhone 13 Series – will be released. iPhone 12 Pro Max. (Photo: Android Authority) So at this point, should I buy an iPhone 12 or should I wait until the iPhone 13 comes out? The answer is simply yes and no, depending on your particular situation, according to Cnet. Depends on the iPhone you are using One of the good reasons to buy a new phone is that your current device is old, outdated. If you are using an iPhone 11 and it is still in great use, upgrading to iPhone 12 at this time is probably not necessary. iPhone 12 and iPhone 12 mini purple. (Photo: Alexander Pobyvanets / HunchMag) You won’t feel a difference in performance or features, especially when compared to what will be on the upcoming iPhone 13. Therefore, waiting a few more months will give you a more perfect answer as to which model to choose, the new iPhone 12 or iPhone 13. If you own older iPhones, from iPhone X and below, the puzzle will be completely different. iPhone 12 is equipped with the Apple A14 Bionic processor and OLED screen, two improvements that represent a major upgrade compared to the phones of a few years ago. The Necessity of 5G . Speed 5G wireless networks are becoming the trend of the future. It is worth mentioning that the iPhone 12 is the first and only phone currently with 5G support. Concept iPhone 13 pink. (Photo: Ali Sayed Ali / ArtStation) So if 5G and access to a cellular network are what you want, right now, the iPhone 12 is your thirst quencher. Of course, the iPhone 13 will probably be compatible with 5G networks, so the choice of waiting or not will be in your hands. iPhone 13 is expected to have many attractive features iPhone 13 is expected to be equipped with new features not found on iPhone 12 series. If rumors are correct, the new generation iPhone will have a 120Hz screen that makes tasks smoother and faster. iPhone 13 build. (Image: Shutterstock) Apple will also upgrade the camera for the iPhone 2021, which it does every year. Analysts Blayne Curtis and Thomas O’Malley of Barclays predict that the iPhone 13 will be equipped with an ultra-wide-angle camera with an aperture of f/1.8, larger than the f/2.4 aperture on the current iPhone 12 series. A large aperture means that the camera sensor will capture more light, promising high-quality photos in different lighting conditions. In addition, the iPhone 13 generation is also expected to be equipped with a LiDAR sensor, which is inherently only on the iPhone 12 Pro Max. Price can be the deciding factor Price is also a factor that many people care about when choosing to buy an iPhone. Many people think that iPhone 12 will drop in price when the next version comes out. (Photo: HKNews) There are also people who believe that Apple will sell iPhone 13 at the same or lower price, similar to what happened with the iPhone 12 series launched last year. However, everything can only be answered when Apple officially confirms it. For now, of course, the choice is yours.

The ruins of the ancient city of Tikal, where the Teotihuacan population was discovered. Autonomous zone in the city To the naked eye – and on archaeologists’ maps – the structure looks like a hill amid the undulating landscape of Tikal, the ancient Maya city-state in the lowlands of northern Guatemala. But when the researchers zoomed in on the image with a laser scanning device called LiDAR (Light Detection And Ranging), they saw a man-made pyramid structure. , hidden under the soil and vegetation accumulated for thousands of years. This structure is actually part of an old residential area, different from most structures that have existed in Tikal. It has a distinctive shape, orientation and architectural features commonly found in Teotihuacan, a powerful city-state belonging to another civilization, near present-day Mexico City, 1200km west of Tikal. Upon closer inspection, archaeologists found that the complex appeared to be a copy of the giant Citadel square in Teotihuacan but was only half the size. The new discovery of a massive monument at the heart of Tikal – one of the most widely excavated and studied archaeological sites on Earth, shows that LiDAR is revolutionizing archeology in Central America, where these sites The jungle often renders satellite imagery useless. From here, however, a difficult question also arises: What role does an area of ​​the remote Teotihuacan city-state play in the heart of this Maya capital? After studying images from LiDAR, Edwin Román-Ramírez, Director of the South Tikal Archaeological Project conducted excavations in the summer of 2020. Digging tunnels into the site, his team made the discovery. Building tools, funeral offerings, pottery, and weapons are typical of early fourth-century Teotihuacan. From censers decorated with the rain god Teotihuacan, to darts made of green obsidian in central Mexico, the site is likely a quasi-autonomous neighborhood in central Tikal. Román-Ramírez said: “We know that the Teotihuacans had some presence and influence in Tikal and nearby Maya areas before 378. But it is not clear how well the Mayans were associated with the most powerful kingdom in the region. . Now there is evidence that their relationship is even closer than that.” Relationship between two civilizations The ruins of the Citadel Square of the Teotihuacan civilization. Thomas Garrison – a geographer at the University of Texas – Austin (USA), specializing in the use of digital technology for archaeological research, said that the above findings proved to a certain extent that the America’s old town isn’t too different from today’s cosmopolitan cities. “There is a mixture of cultures and people of different backgrounds and languages ​​coexist, maintaining their identity in one city,” he said. A study funded by the Pacunam LiDAR Initiative, which published groundbreaking findings in 2018, reveals a vast network of ancient cities in the Maya lowlands, home to millions of people. people, more than previously thought. Scientists Edwin Román – Ramírez noted that the above findings do not confirm that the builders of the complex came from Teotihuacan. “But what we found shows that, for more than a century people who are more or less familiar with Teotihuacan culture and traditions have lived there, in their own region,” he said. Based on ceramic designs found in the ruins, the team estimates that construction at the site began at least 100 years before 378, an important date in Mayan history. According to the Maya inscriptions, the king of Teotihuacan sent a general called the Born of Fire to overthrow the king of Tikal, Jaguar Paw, and put his young son in charge of the country. Born of Fire arrived in Tikal on January 16, 378, the same day that Jaguar Paw “entered the water” – a Mayan metaphor for death. After being annexed, Tikal flourished for several centuries, conquering and pacifying neighboring cities, and spreading their culture throughout the plains. Tikal’s hegemony during this period is well documented, but it is not clear why, after decades of friendly coexistence, Teotihuacan turned his back on his former ally. Further excavations at Tikal may provide new insights, but a recent discovery in Teotihuacan suggests that cultural conflict may have sparked the breakup between these two powerful city-states. A team of scientists led by Nawa Sugiyama, an archaeologist at the University of California, Riverside (USA), has discovered a “Maya house” at Teotihuacan. The opulent buildings here are decorated with splendid Mayan murals, suggesting that the inhabitants were either elite diplomats or aristocratic families. But just before Tikal was annexed in 378, the murals were smashed to pieces and buried. A nearby pit was filled with shattered human skeletons, indicating the sudden shift from diplomacy to violent confrontation between the two city-states. “What went wrong in that relationship, when a bunch of elite Maya residents were massacred, their buildings were demolished, all their belongings were thrown away, and then their homeland was conquered. ruled by a child king?” asked Francisco Estrada-Belli, an archaeologist at Tulane University. It is also one of the great mysteries of Central America that scientists are trying to answer.

If previous rumors are correct, Apple will not change the number and screen size of this year’s iPhone series. That means we will continue to see 4 models of iPhone 13, iPhone 13 Mini, iPhone 13 Pro and iPhone 13 Pro Max launched this fall. High refresh rate monitor At the present time, all iPhone models, including the latest iPhone 12 series have screens that support the standard 60Hz refresh rate, while most smartphone Android now has a high refresh rate screen, 90Hz or 120Hz. There is speculation that this year’s iPhone 13 generation will be equipped with an LTPO OLED screen that supports 120Hz refresh rate, promising to give users a better experience when playing games as well as in daily use. Larger camera sensor The camera system of the current iPhone 12 series includes a main sensor and an ultra-wide-angle lens. The “Pro” models also add a telephoto camera and a LiDAR scanner. These phones are also equipped with a lot of useful photography features such as night mode – Night Mode or improved HDR mode. According to rumors that have appeared recently, the camera system of the upcoming iPhone 13 series will be upgraded quite a bit compared to the previous generation. These cameras will use sensors with larger sizes, promising to bring better image quality to users, especially when shooting in low-light environments. In addition, the new iPhone models are also expected to add a periscope lens to improve zooming, an upgraded ultra-wide-angle lens for night mode photography, and a LiDAR sensor that will be available on all models. all versions instead of just the “Pro” and “Pro Max” models. The Return of Touch ID iPhone 13″ series is also rumored to have the return of Touch ID. However, this feature can be integrated below the screen instead of a separate physical button. Some people expected this to happen with the iPhone 12, but in the end it didn’t happen. Nor does it rule out the possibility that this technology could be ported to the iPhone 14 years later. While the iPhone 12 series lacks a Touch ID fingerprint sensor, Apple’s iPad Air 2020 has integrated Touch ID in the power button. If the iPhone 13 copies this from the iPad Air, it will be a great addition this year, as Face ID won’t work with a mask on (unless you have an Apple Watch and update to iOS 14.5). There is still a Lightning port but the headphone jack is removed The iPhone 12 doesn’t have a 3.5mm headphone jack and we shouldn’t expect this year’s iPhone 13 series to have it. But the Lightning port could be a different story now that Apple has introduced MagSafe charging capabilities. Previously, famous analyst Ming-Chi Kuo predicted that iPhone 13 models will still have a Lightning port, with the exception of the iPhone 13 Pro Max, which may have no port at all. Ceiling paint According to S-forum

iPhone 13 can satisfy the user ?. Photo series by MySmartPrice posted in April shows the position of 2 cameras on the iPhone 13 arranged diagonally instead of vertically. The top right corner is still the LED flash, while the lower left corner is the microphone. The design language of the device remains unchanged with 4 square frames, 2 flat glass surfaces similar to the iPhone 12 series. The camera can be folded diagonally instead of straight like previous generations. In the video on hand the iPhone 13 Pro model is channeled Macotakara Sharing, the machine’s hole length is 26.8 mm, while the iPhone 12 Pro is 34.83 mm, about 22% shorter. Based on the model, Apple will move the speakerphone to the top edge while pushing the remaining sensors lower. The camera on the iPhone 13 has the potential for better zoom capabilities, the ultra-wide-angle camera is improved to capture better nights than the iPhone 12. Meanwhile, the LiDAR depth sensor will be available for all four versions. In early May, the model of iPhone 13 Pro Max due to the channel Unbox Therapy Share shows that the rear camera cluster is larger than the previous one, implying that the camera on the machine will be upgraded. Many users are expecting the Touch ID fingerprint sensor feature back in the iPhone 13. Many users are expecting the Touch ID fingerprint sensor feature that could be brought back to the iPhone 13 by Apple and placed under the screen. According to the CNET This feature was once rumored on the iPhone 12 line, but the official product is only equipped with Face ID facial recognition. If not integrated into the screen, Apple can embed Touch ID into the power button similar to the iPad Air 2020. “Super leaker” Ming-Chi Kuo predicts that the iPhone 13 Pro Max version will remove the Lightning connection port, switch to the MagSafe wireless standard to charge and transfer data. The rest of the iPhone 13 models still use the Lightning port. This is Apple’s long-rumored plan, the rumor of it appearing more after MagSafe came equipped with the iPhone 12 last year.

Ancient Mayan civilization simulated on a 3D model. The laser survey showed that in a mountainous region north of Yucatán, called Puuc, the Mayans built remarkable structures, including artificial reservoirs, more than 1,200 stoves, several fields. ladder to cultivate … Research lead William Ringle, professor emeritus of anthropology at Davidson University in North Carolina, USA said: “It looks like this is a very prosperous area because we have all the stone houses. build. ” Furthermore, the Mayans of Puuc built four major towns dating from the Middle Ages (700 BC to 450 BC) and population centers dating from 600 to 750 AD, during the Late Antiquity period. dictionary. While these structures were recorded, laser data analysis revealed that these Puuc communities had distinct city layouts that were not seen in other Maya regions. Researchers have known of the ancient Mayan settlements of Puuc since the 1840s, but there has never been a comprehensive survey of the area so far. By calculating with laser light, a software can create a detailed 3D topographic map of ancient Mayan civilization. Researchers spent about 20 years doing basic research in the Puuc region. Analysis of the lidar maps, which encompass about 237 square kilometers, revealed 7,900 housing quarters, including on the hills, indicating that the Puuc area with a large population was concentrated mainly on the Different communities, with a few in the hinterland of Puuc. Many of these residential structures still have stone veins marking different rooms – each house has about 2-3 rooms. These details suggest that Puuc may be one of the most densely populated areas in the Maya Lowlands, an area that includes parts of modern-day Mexico, Guatemala and Belize. Despite the densely populated, it seems that the people in Puuc mainly live in peace; the communities are quite close together – usually between 5 and 10 km, but there is no evidence of any defensive structure. “There are images of warriors on some of the sculptures, but it’s not to the point where people stop themselves from the neighbors,” the researchers said. Water reservoirs A densely populated area needs a lot of water, but Puuc, like the rest of Yucatan, is mostly on limestone, a porous rock. Since there was no water or river or lake, people had to find other ways to get it. Puuc is located on a hilly and raised area, making it above groundwater level. To solve this problem, the Mayans built “chultunes”, or tanks, that were lined with mortar to collect rainwater. The Mayans also built “aguadas”, or reservoirs, with long drainage channels. Lidar’s survey revealed that some of these channels were several hundred meters long. Terraces The lidar survey also revealed evidence of an intensive and widespread rock-producing industry, consisting of quarries and 1,232 circular stoves, potentially used to sinter sandstone so that produce lime, or calcium oxide. This lime is probably used as a construction mortar and to help soften corn. “When people down there cook corn, they usually soak it in lime the night before to soften it a bit, and then they will grind it,” says Ringle. Therefore, lime is an essential commodity, even at the household level. ” The number of stoves was a surprising revelation, Ringle added. They are everywhere. And that shows that it’s a sizable industry in Puuc. Other research has shown that these stoves can be operated using very little firewood. “It tells us that people probably had the raw materials pretty close at hand, even though they didn’t burn the entire forest,” Ringle said. The lidar image also showed the first clear evidence of the ladder at Puuc, actually all north of Yucatan. Although the area has hundreds of hills, only 8 hills are terraced fields for cultivation. This shows that this practice is not popular in Puuc. The ancient Maya civilization existed for more than 2,500 years, before the people mysteriously abandoned their city.
