New car radar can easily see the obstacle right around the corner

At Princeton University (USA) team under the leadership of Professor Felix Heide has developed a prototype radar devices that can track the objects located around the corner from the observer, outside of direct visibility. This technology is intended for ground transportation, it gives an opportunity to detect an obstacle on the road to an intersection.

The technology is based on the Doppler effect and the ability of radio waves to be reflected from different objects, changing the vector of its movement. Small radioizluchenie the machine sends pulses forward, but at such an angle that they bounce off different objects and got the corner of the building. There, in the presence of interference, they again reflected, and the signal return to the car. It remains to analyze its characteristics, to understand at what distance the object is around the corner, how fast moving etc.

As potential interference, and surfaces for the deflection can be set, to increase the processing speed uses a special AI. Compared to similar systems based on laser radar devices have much smaller energy consumption. In the current version of the system is adapted to detect people and cyclists, but its not hard to configure, for example, to identify machines to be integrated in the autopilot system, put the mining truck etc.

Physicists have learned to turn plastic bottles in supercapacitors

Scientists from the University of California, riverside have developed a technology to produce components for supercapacitors from regular waste. We are talking about polyethylene terephthalate or PET, which is made most of plastic bottles. This material is from an economic point of view is significantly superior to high-tech raw materials, like graphene or carbon nanotubes. […]

Our Solar system is most similar to space croissant

The sun emits powerful electromagnetic winds that envelop the planet in our solar system like a giant bubble. This magnetic bubble is called the heliosphere and protects the planet from dangerous space radiation. Scientists have long believed that the heliosphere is in the form of a comet – with a distinct nose and long flowing […]

Some homemade masks turned out to be more dangerous than no

Despite the fact that the industry has recovered from the shock of the first days of the pandemic COVID-19 and now produces enough facial masks of different types, most people in the world due to various reasons use homemade versions. Everyone understands that they are less effective than professional medical model, but the question is: […]
