Application of SP3384NUTG assemblies:

Industrial low voltage differential interfaces (LVDS);
Data processing and storage centers and telecommunications:
5G wireless devices
WAN/LAN equipment
Servers
2.5G/5G/10G Ethernet
Consumer electronics and wearable devices.
The SP3384NUT TVS assemblies are available in miniature µDFN (3 x 2mm) packages. They have an operating temperature range of -40...125°C and comply with the requirements of AEC-Q101.

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 ... >>

petapixel camera 13.08.2013

DARPA experts are assembling a prototype camera, which in the future will be a million times more capable of capturing and processing images than human vision.
DARPA has made new strides in developing camera technology capable of producing petapixel images in the future. In August 2013 and 2014, the assembly of new AWARE 2 and AWARE-10 camera prototypes will be completed: 5- and 10-gigapixel cameras that have a large field of view and the ability to simultaneously identify multiple objects. According to these parameters, they will surpass human vision by 30-50 times.

In August, experts working on behalf of the defense science agency DARPA will reach a new milestone in the development of a unique video camera capable of observing the environment with a resolution and scale unattainable by any living creature on our planet.

Work on a new camera is being carried out as part of the AWARE project by scientists and engineers from Duke University. They have already achieved significant success, in particular, the second generation of AWARE 2 cameras was created in April. This is an array of 98 14-megapixel micro-cameras with a total resolution of 1,4 gigapixels, which form a camera with a field of view of 120x40 degrees and capable of shooting at a frequency of 10 frames per give me a sec. Each micro camera can take 4384x3288 pixel resolution pictures, and the entire camera can take 63000x18000 pixel composite pictures.

The unique features of the camera are provided by its original design: the light from the lens does not fall on a flat matrix, but on the inside of the hemisphere, where miniature cameras are placed, which allows you to shoot high-resolution panoramic shots. In the future, such cameras are planned to be installed on military aircraft and robots, which will make it possible to observe a vast area and at the same time increase the scale of the selected area. In order to understand the advantage of the new technology, imagine that the AWARE camera can recognize the faces of half the people in a football stadium.

And although the angular resolution of cameras is limited by atmospheric effects, it is possible to create photo and video cameras that will take photos and videos with a zoom of up to 30-50 times. If such video cameras are used, for example, when shooting sports events, then viewers will be able to independently enlarge the part of the television picture they are interested in and watch high-resolution video. In fact, AWARE cameras cancel the concept of a change of shot - the viewer himself can choose whether to watch a panorama or a close-up.

Of course, such opportunities will require powerful communication channels capable of transmitting a huge amount of information. Also, developers are trying to replace the expensive glass lenses of AWARE cameras with cheaper plastic ones, which will reduce the weight and cost of a new type of device.
