Why add airbags to waterproof mobile phone bags?

Jeff Bezos, CEO of Amazon, must have dropped his cell phone a lot. Otherwise, why does he need to apply for an expensive and extremely complicated patent for "anti-collision system" in his own name? This system senses the occurrence of free fall through the dynamic sensor in the smart phone, and then sends a signal to the patented mobile phone protective cover, and activates the airbag to prevent further impact injury. It is very common for a mobile phone to have problems due to accidental drop. Therefore, in order to avoid this kind of accident, various mobile phone protection products have been launched. Last week, Amazon CEO Jeff Bezos applied for a patent to protect mobile phones, which is to protect mobile phones through airbags. Airbag protection is now widely used in cars, and the increasingly high technical content of mobile phones also provides a foundation for airbag protection. Use the gravity accelerator of the mobile phone to judge when the mobile phone falls, and then use airbags or air jets to protect the fallen mobile phone. In addition to the built-in accelerator of the mobile phone, the laser range finder is also used to judge the falling speed of the mobile phone. In addition to speed and distance, we also need to know the hardness of the falling place. When you fall on a quilt or on a hard road, the measures taken are different. By using X-ray or radar system, the mobile phone can decide whether to use a jet plane or an airbag to avoid unnecessary waste. In fact, drop protection has been applied in digital products, such as Thinkpad, HP and other brands of high-end business notebooks will have hard disk drop protection. But in the era when the value of mobile phones is getting higher and higher, this demand is more and more necessary. However, the patent proposed by Amazon is somewhat unexpected, but in any case, we still expect this technology to be used on mobile phones as soon as possible to make our mobile phones more secure.
