Title: SYSTEM FOR BLOCKING THE SIGNAL OF A CELLULAR PHONE USED IN AUTOMOBILE VEHICLES OF ALL TYPES
Abstract:
The present invention patent (1) is aimed at the field of road safety, more specifically the field of prevention of traffic accidents, by restraining the use of a cellular phone for making or receiving calls, thus preventing the driver from becoming distracted and causing an accident, the invention being characterised in that it comprises an electronic device provided with sensors and other components that generate an electromagnetic shield inside the vehicle, more specifically inside the driver’s cab, which stops both the signals (4) emitted and the signals (5) received by the cellular phone (6). In operation, the sensors installed in the device actuate specific components that generate an electromagnetic shield (2) when the driver inputs a number or actuates the call reception key, and increase the signal/noise ratio when the use of the cellular phone (6) is sensed by the sensors, whenever the automobile vehicle (3) is moving or turned on, thus preventing any calls to be made or received. In other words, when the automobile vehicle is stopped and turned off, the cellular phone can be used normally.
