Wi-Fi holographic imaging: the world from the perspective of Wi-Fi

In the wilderness, two smart figures moved around, and in front of it was a wild deer that was fleeing, behind it was a hungry cheetah. The wild deer can't decide whether their destiny is to become a delicious dinner or to escape from the sky. Just because there is no hidden concealment, they have to become a belly meal. Privacy is important, at least in nature driven by the wild. Sometimes the chance of survival is only once, there is no regret, once the whereabouts are revealed, the whole market is lost.

The ability to see through is always among the best. Some time ago, Lei Feng.com found a paper published by the Technical University of Munich, and their researchers developed a technique for generating three-dimensional holograms of the surrounding environment using Wi-Fi signals.

USB Slip Rings are an increasingly popular way to provide power and data to rotating devices. By using a slip ring, you can avoid having to run cables through a hole in the device's enclosure, which can be difficult and messy. USB slip rings also provide a convenient way to update firmware or change settings on the device without having to open the enclosure.
