Sony IMX324 Ultra-Sensitive Automotive Image Sensor

28.10.2017

Sony has introduced a new 7,72-megapixel IMX324 sensor. The sensor has 7,42 million effective pixels, the highest in the industry. Sensor aspect ratio 1/1,7. Sensitivity is determined at the level of 2666 mV. The resolution of the sensor is such that the camera using it is able to obtain a clear image of a road sign from a distance of about 160 meters. A man can't do that.

Such sensors are designed to work in ADAS (advanced driver-assistance systems) electronic driver assistance systems. This development, according to Sony, is compatible with the EyeQ4 and EyeQ5 image processors from Mobileye, previously acquired by Intel.

At night, the IMX324 sensors work both in "burst" mode with RCCC filters (red, three clean), when four adjacent pixels work as one (pixel binning mode) to increase sensitivity, and in alternating light / shadow mode. The pixel array for each frame alternately switches from high sensitivity mode for capturing images in dark areas of the scene, to capturing highlights in bright street lighting and in the light of car headlights. The final image, which is "glued together" by a specialized processor, is detailed and relatively contrasting in the shadows and in the light.

Sony IMX324 sensors are capable of capturing images with ambient light as low as 0,1 lux. It's like shooting under the light of a full moon on a cloudless day. Sensors will help to distinguish a pedestrian on the track and possible obstacles at a great distance. Sensors, which is typical for Sony, are multi-layered and designed for stacking, which allows you to make cameras with them compact.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Milk inoculation 07.08.2004

Five-year-old Australian Alexander N. was taken to a clinic in Jena (Germany) to be treated for a rare and severe type of allergy: the boy could not tolerate cow's milk proteins. One thousandth of a percent of these proteins (and they are sometimes added to the most unexpected food products) was enough for the child to develop a swelling of the larynx that blocked breathing.

The treatment turned out to be simple in principle, but requiring strict medical supervision. For five days the child was given the same cow's milk, but in greater dilutions. We started with a homeopathic dilution a million times: for a thousand liters of water (per cubic meter) one milliliter of milk. And then every twenty minutes the dilution was halved.

Already on the fourth day, Alexander began to receive pure milk, and nothing terrible happened. Now, in order for the results of the treatment to be preserved, he must drink half a glass or a glass of milk daily.

The method is not suitable for all cases of food allergies. For example, it is unsuitable for a fairly common nut allergy.
