New image sensor for automotive cameras

18.11.2013

Toshiba Corporation announced the start of deliveries of new 1/4-inch CMOS image sensors. New products with VGA resolution are aimed at use in car cameras.

The TCM5126GBA sensor includes an HDR (high dynamic range) feature. The device is made in a small format case using TSV (through-silicon via) technology. Compared to competing solutions, the sensor has a 30% smaller overall dimensions. The device supports the function of mirroring the image relative to the vertical and horizontal, the digital zoom function, which may be useful in some camera modes, for example, when parking on the rear view cameras.

Of the characteristics of the sensor, a pixel diameter of 5,6 microns and support for video recording at speeds up to 60 frames per second are noted when shooting at maximum resolution.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

New type of high performance permanent magnets 03.11.2017

Researchers at Lawrence Livermore National Laboratory have developed a new type of high-performance permanent magnet that should address the shortage of conventional samarium and neodymium-based permanent magnets. The basis of the new magnet is the structure of magnets based on the compound of samarium and cobalt (SmCo5), but most of the scarce and expensive cobalt atoms have been replaced by iron and nickel atoms.

Modern neodymium magnets have an advantage over magnets based on samarium and cobalt in terms of energy performance. The new magnet eliminates most of the known shortcomings of SmCo5 magnets, while maintaining their original high temperature efficiency.

Unfortunately, the replacement of the absolute majority of cobalt atoms with iron atoms having a larger magnetic moment makes the hexagonal crystal lattice of the magnet material thermodynamically unstable. Scientists at Livermore National Laboratory were able to get around the problem of instability by adding "stabilizing" nickel atoms to the crystal lattice.

Using the calculations of the electronic structure models of the new SmCoNiFe3 magnet, it was shown that this magnet has a number of remarkable magnetic properties and is able to replace SmCo5- or neodymium magnets in many areas of their application. "This is a very timely discovery," says Per Soderlind, lead researcher. cobalt, very inexpensive and available."

The researchers are currently awaiting a patent for a new kind of permanent magnet they have developed. And after obtaining a patent, they will begin to develop a method for the production of such magnets on an industrial scale.
