American developers have created an "anti-spy" bracelet from microphones (Video)
The new development was invented by experts from the University of Chicago. They believe that the prototype of their device is the future in the field of intelligence.
The essence of the bracelet is the production of ultrasonic waves suppressing "white noise". These are the signals emitted by the majority of existing microphones. Thus, frequencies that a person does not even hear become just a hiss that blocks speech.
The presented prototype looks rather unwieldy. But its size and appearance did not affect the functionality declared by the developers. This has been proven empirically.
University students took part in testing the device. They noted the positive impact of this miracle gadget. Students felt incredible peace of mind during and after using it. According to the authors of the project, this is due to the action of ultrasonic rays on the human body.
Such inventions are considered not know-how in the electronics market. There are plenty of anti-spyware solutions. But the essential difference between the bracelet of the Chicago scientists is that it is able to cover the sound "dead zones" with the help of human movements.
Typically, off-the-shelf devices only block one sound source. And if there are several obstacles at once, then you have to resort to additional help. The bracelet of specialists from Chicago is able to suppress noise in different directions at once.
At this stage, scientists are preparing for the presentation of their project at a specialized conference. They organize the materials in order to explain as accurately as possible the essence of the new "anti-spyware" gadget.
