Remember that old glory of telecommunications? That Ericsson on the shields in the 90s, as well as the protagonist of an unfortunate attempt to merge with Sony? He patented a rather special anti-theft device for smartphones.
And yes, I thought I had seen it all with the apocalyptic flop of the old t28. Who among you remembers it? Nobody, right? Here you are. I knew who I would have sworn. Blessed innocence! It's one of the reasons why I sometimes envy the new generations ...
It is not easy to steal it. It has a peculiarity: it modifies its grip according to the grip. In other words? It can fall out of your hand if you snatch it from its rightful owner.
Phone Arena, a sector website, reports in an article the characteristics of the system called "adaptive friction". This technology evaluates the user's grip (from internal sensors) and modifies its handling.
The system will recognize the owner and become slippery with an attacker. Such as? Easy. Distinguishing users from other parameters such as fingerprints or blood pressure (measured through the classic heart rate sensor. It is now available in different models).
At that point, the "hysterical" reaction of this real anti-theft device for smartphones is triggered. He literally gets shivering!
When the parameters measured by the sensors tell the phone that it is in "hostile" hands, the device activates a micro-vibration ("almost ultrasonic," I read in the article) which makes it unstable to the touch.
Friction is reduced, and your smartphone gets out of hand: that's it. The thief is duped. The phone is supposedly broken, but it doesn't matter - it's a matter of principle!
Watch out for malfunctions!
When this patent (here it is) will be translated into a real device the owner could pay an arm and a leg to find a bar of soap on the first phone call. "It's just that when I read your mother's display, dear, everything gets out of hand!"
