This change is both modern, convenient, and does not affect the usage habits of customers, while helping to reduce potential hardware failure points, better water resistance, etc. (Artwork: ConceptsiPhone / YouTube) Most recently, a patent application filed by Apple with the US Patent and Trademark Office (USPTO) shows that “Apple defect” is working on a “capacitive sensor input device”. These input devices, also known as buttons, will be transformed into “invisible” sensors – appearing when touched and disappearing when not in use, according to Cnet. (Artwork: Techy Paradise / YouTube) This hints at the possibility that it will appear on the next-generation iPhone, or maybe the 2022 iPhone once Apple feels it is appropriate to bring a change on its iPhones. It’s really not a vague concept that Apple is looking to apply this change to future iPhones, as many rumors have surfaced recently. (Artwork: Gearcoupon) According to many leaked sources in the past, the iPhone 13 will bring the fingerprint sensor back. But instead of using a physical Home button, the new fingerprint sensor will be integrated under the surface of the phone’s screen. This change certainly fits with the minimalist, buttonless design aesthetic that Apple is aiming for. In the past, Apple has killed the 3.5mm ear jack since the iPhone 7, iPhone 7 Plus in 2016 and rumors suggest the company wants to do the same with the Lightning port. (Artwork: Marques Brownlee / YouTube) If the iPhone 13 gets rid of the Lightning port and supports MagSafe wireless charging, it will become the first generation of iPhones completely without Apple’s connection port. Therefore, the company completely has the basis to kill the physical button. Of course, this is just a patent application, which means that an iPhone 13 without physical buttons is unlikely to appear. It is also possible that Apple will bring this change to a completely different product than the iPhone.

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.

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.

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.

The scientific experiments were led by Leibniz Institute of Animal and Wildlife (Leibniz-IZW) and chaired by Professor Richard A. Holland (Bangor University, UK) and Dr. Gunārs P ē tersons (Latvia University of Life Sciences and Technology). It shows that now the cornea of ​​the eye is the site of an important sense in bat migration. A bat’s directional sense is its eyes. If the cornea is anesthetized, the otherwise reliable sense of orientation will be disturbed while the ability to detect light remains unaffected. The paper was published in the scientific journal Communications Biology. In the bats of one experimental group, the scientists locally anesthetized the cornea with a drop of oxybuprocaine. This surfactant is widely used in ophthalmology, where it is used to temporarily desensitize the cornea when the human or animal eye is over-irritated. However, an effect on orientation has not been noted before. In another experimental group of bats, the team anesthetized the cornea of ​​one eye. Individuals in the control group were not given anesthesia, but were instead given isotonic saline as eye drops. All animals in this scientific experiment were captured in a migratory corridor on the Baltic coast and released individually in the open field 11 km from the place of capture. First, the scientists used bat detectors to ensure that no other bats were in the field at the time of releasing the test animals. The direction of movement of the released bats was observed without knowing how the bats were treated experimentally. Dr. Oliver Lindecke, first author of the paper, explains: “The control group and the anesthetized group with unilateral corneas clearly oriented to the expected south, while the bats with corneas were anesthetized. both sides fly in random directions.” He added: “This clear difference in behavior suggests that corneal anesthesia has disrupted the sense of direction, but orientation seems to still work well with one eye. The corneal treatment wore off after a short time, and the bats were able to continue their journey south after the trial.” To rule out the possibility that an irritated cornea also affects visual sensation and that the scientists could therefore draw erroneous conclusions, they performed an additional test. Again, they examined whether the bats’ response to light changed after anesthetizing the corneas on one or both sides. “We know from previous research that bats prefer a illuminated exit when leaving a simple Y-shaped maze,” explains PD Dr Christian Voigt, head of the Leibniz-IZW Department of Evolutionary Ecology . “In our experiment, animals that were anesthetized either unilaterally or bilaterally also showed this preference; we can therefore rule out that light vision has been altered after corneal treatment. The ability to see light will of course also affect long-distance navigation. ” For instance, many vertebrates such as bats, dolphins, whales, fish and turtles can safely navigate in the dark, whether it’s under the open night sky, when it’s cloudy at night or in caves and tunnels as well as in the depths of the ocean. For decades, scientists have searched for a sense or a sensory organ that enables animals to perform navigational and orientation tasks that seemed unimaginable to humans. Magnetic sensation, so far only demonstrated in certain mammalian species. Experiments show that iron oxide particles in cells can act as “microcompass needles”, as is the case with some species of bacteria. The team’s experiments on Lindecke and Voigt provide for the first time reliable data for determining sensory orientation in migratory, free-migrating mammals. Exactly what a bat’s cornea looks like, how it works, and whether it is a long-sought magnetic sense need to be pointed out in future scientific investigations.

The bat’s sense of direction are the eyes. Mammals see with the eyes, hear with the ears, and smell with the nose. But which senses or organs allow them to direct their migration, sometimes beyond their feeding area and thus require extensive orientation? Scientific experiments led by the Leibniz Institute for Animal and Wildlife Research (Leibniz-IZW) led by Professor Richard A. Holland (Bangor University, UK) and Dr. Gunārs P ē tersons (Latvian University of Life Sciences and Technology).
