Toyota will help build safe talking roads

24.11.2012

To improve road safety, Toyota plans to introduce new communication technologies that will ensure that not only vehicles communicate with each other, the Japanese automaker wants to teach cars to "speak" to the road. To test the Intelligent Transport System platform, Toyota has set up a proving ground that simulates real road conditions.

The ITS Proving Ground is equipped with multifunctional communication systems that notify compatible vehicles of approaching vehicles, pedestrians, traffic lights and more. The system operates in the 700 MHz band, it provides reliable reception even in the most difficult conditions, with this technology the driver is notified of the deterioration of the road condition along the route if it is out of the driver's field of vision, as well as what traffic signals will be when entrance to the intersection. In addition to the obvious benefit in terms of traffic safety, this allows the driver to slow down or pick up speed in a timely manner, thus regulating fuel consumption.

Other objects, including brick walls, also “talk” with the car, a unit called Toyota Intelligent Clearance Sonar finds a common language with them. It monitors objects around the car and when approaching a source of possible danger, the brake system is activated, the engine slows down, and the driver receives an audible notification. Other systems are being tested at the test site, including the Drive-start Control function, which prevents the driver from accidentally shifting into unnecessary reverse or forward gear in a stressful parking situation, and the Pre-collision System (PCS), which prevents rear impacts if the speed the car in front is significantly lower. The manufacturer promised to install PCS on one of the nearest models, while Intelligent Clearance Sonar and Drive-start Control will appear a little later.

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, ... >>

X-Pro3 Mirrorless Camera 24.10.2019

The Japanese company Fujifilm has introduced a new flagship model of a series of mirrorless cameras X - X-Pro3. The device is based on a 4 megapixel APS-C back-illuminated X-Trans CMOS 26,1 image sensor. The X-Processor 4 processor, already familiar to photographers from the Fujifilm X-T3 and X-T30 cameras, is responsible for processing the captured frames.

Phase-detection autofocus works down to -6 EV. Light sensitivity - ISO 160-12800 with an extension to ISO 80-51200. The novelty has received an improved hybrid viewfinder, in which the optical channel is combined with an OLED display with the ability to switch between them. An interesting design feature is that the built-in liquid crystal display is not visible in normal mode. In order to use its services, you will have to tilt the screen down at an angle of up to 180 °.

And so only a tiny auxiliary display with a diagonal of 1,28 inches is available. The camera can shoot video at resolutions up to DCI 4K 4096 x 2160 pixels. There are Wi-Fi IEEE 802.11b/g/n and Bluetooth modules. The body of the novelty is protected from dust and splashes. Camera dimensions are 141 x 83 x 46 mm, weight - 497 g.

The Fujifilm X-Pro3 will go on sale in November for $1800.
