The traffic light will help the car

30.03.2014

The Audi Group, part of the German automaker Volkswagen, has developed an intelligent system that informs motorists about the work of traffic lights in the city. An electronic assistant called Audi Traffic Light Recognition is able to reduce the number of traffic jams, as well as reduce fuel consumption and emissions of harmful substances into the atmosphere.

According to the idea of the Ingolstadt developers, data on traffic signals on the way of the car will be displayed on the dashboard. There, the driver will also be able to see a hint with the optimal speed, which must be selected in order to pass the nearest intersection on a green light. To do this, car electronics will be connected to the city's traffic light control center via the Internet.

If the vehicle stops at a red light, the driver will see a countdown timer in front of him, showing the time until the green light turns on. At the same time, the technology will be able to work in tandem with the Start / Stop system, which turns off the engine during downtime and starts it again when the driver presses the gas pedal. In the case of Audi Traffic Light Recognition, the engine will start five seconds before the traffic light turns on.

Audi claims that by teaching cars to interact with traffic lights, it will be possible to reduce the level of harmful emissions by 15%. The introduction of the development in the territory of Germany alone will save about 900 million liters of fuel. In addition, the project will help optimize car traffic by reducing the number of traffic congestion.

The traffic light recognition system is being tested in several cities, including Verona, Berlin and Las Vegas. According to the automaker, the new product is ready for mass production and can be installed in all new Audi models, but first it is necessary to obtain permission from the authorities to implement the project.

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 ... >>

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, ... >>

The laser can peek through the keyhole 14.09.2021

The ability to "look" into enclosed spaces has long been a science fiction and "superhero" skill. However, researchers from the Computational Imaging Lab at Stanford University, using NLOS (non-line-of-sight imaging) technology as a basis, have ensured that a single beam of laser light penetrating into a closed room, let's say, through a keyhole, will allow you to see all physical objects in this room.

NLOS imaging technology has been a well-known technology for a long time. Based on this method, "smart" cameras have already been created that can look around corners and shoot objects hidden by any obstacles. However, most of the previous implementations of the NLOS-survey technology made it possible to see fairly large objects and flat surfaces, for example, walls in a room. NLOS technology is a very promising technology for a number of areas. Self-driving robotic cars, for example, can use this technology to "look" around corners and recognize potential dangers before a normal camera or human driver can see them.

The technology works as follows - the laser emits a series of short pulses of a certain duration, going through a certain time interval. The laser light is repeatedly reflected from the surfaces of objects, including those hidden by obstacles, some of it comes back and is captured by the camera sensors. Information about how much time has passed between the initial pulse and the registration of the reflected light signal is processed using complex mathematical algorithms that recreate images of objects that do not fall into the direct field of view of the camera. The final images cannot boast of high quality and resolution, but a person can easily recognize objects in these images.

However, the existing implementations of NLOS technology have a number of serious limitations, the quality of its work depends very much on the area and reflectivity of the surface of hidden objects. This, and several other limitations, have made attempting to film from the outside of an enclosed space nearly impossible until recently.

The keyhole method developed at Stanford is so named because it requires only a tiny hole through which a laser beam can illuminate a small spot on the opposite surface. A huge number of photons are repeatedly reflected from the surfaces of walls and objects in the room, but only a small number of photons manage to return back and get to the surface of the avalanche photodetector, which is capable of registering and measuring the arrival time of even single photons.
