Mitsubishi Electric technology monitors the attentiveness of the driver

31.10.2015

Mitsubishi Electric has unveiled technology that will monitor driver alertness and fatigue while driving using a machine algorithm known as "deep learning".

According to representatives of the company, there were no such solutions in the automotive industry before. The technology introduced by Mitsubishi Electric monitors the speed, trajectory, smoothness of the steering wheel, as well as the driver's heartbeat, tilt of his head and other parameters in real time. All this helps to prevent possible traffic accidents.

Using data from previous trips, the system compares the driver's current driving behavior with that of "normal driving" and alerts them to danger in the event of deviations.

Mitsubishi Electric claims that the new technology has reduced the number of errors in predicting driver behavior by 66% compared to the previously used algorithm.

The technology will be demonstrated at the Tokyo Motor Show 2015, which will be held from October 29 to November 8. Commercial implementation of the technology is expected in 2019.

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, ... >>

Magnetic tumbler for cage 19.02.2008

US scientists are learning how to use magnets to control the behavior of cells. To make a cell do a job - to beat an enemy microbe or produce insulin - it is necessary to act on its corresponding receptor. As a rule, doctors do this with the help of artificially administered hormones.

"We propose to go down a completely different path - to use nanomagnets," says Dr. Don Ingber of Boston Children's Hospital. In their first experiments, the scientists created magnetic particles 30 nm in size with an inner core only 5 nm in diameter. Particles of this size turned out to be in a superparamagnetic state, that is, by applying a magnetic field, they could be transferred many times both to a magnetic and a non-magnetic state. Each particle was combined with one antigen molecule corresponding to the receptor of immune system cells.

"One antigen per particle is very important," says co-worker Dr. Robert Mannicke. "We wanted to attach each particle to only one receptor so that we could control a single cell." As the experiments showed, it was possible to organize such control: cells, to the receptors of which nanomagnets were attached, under the influence of a magnetic field, opened channels for the passage of calcium ions inside. And without a magnetic field, nothing like this was observed.

"We hope that in the future, with the help of magnetic nanoparticles, it will be possible to control many processes in a living organism and at the same time do without drugs. For example, a person with diabetes, after eating sweets, will be able to stimulate insulin-producing cells transplanted under his skin with a magnet," Don Ingber says.
