Raytheon Company has filed a patent application on a fundamentally new type of sonic weapons, based on the use of infrasound. The action of infrasound emitted by these weapons, leads to difficulty breathing among people who are in the range of the weapon, as the frequency of infrasound specially chosen for the resonance with the beating human heart, it leads to an infringement of the heart. Engineers of Raytheon offer portable versions of these weapons, in which the infrasound transducer is installed on protective shields of police officers, while perhaps not only remote on individual weapon shield, but also remote control of all the weapon shields, which will greatly enhance the action of the weapons in certain areas. Raytheon Company is known as a major supplier of the Pentagon, about 95% of income of Raytheon in 2010 amounted to orders of the Pentagon.
