United States invented silent silent language detectors also play phone

Think this would be like the scene: four weeks everyone in the cell phone, but you can not hear them speak. U.S. Defense Advanced Research Projects Agency (DARPA) for the U.S. military has invented such a device, it can be the speaker's nerve and muscle activity detection language, callers simply no sound, civilian equipment must also quickly available.

This system is composed of Massachusetts, Worcester Polytechnic Institute, Rick Brown, the Defense Advanced Research Projects Agency developed with, mainly rely on the neck of a set of tuned electromagnetic resonating collar (TERC) to achieve the above functions, which is a sensor that uses a magnetic resonance imaging for the design of sensor technology, the collar can detect the change in capacitance caused by vocal fold vibration, the original is to help people in the voice of a call in a noisy environment.

In addition, the U.S. Defense Advanced Research Projects Agency has also purchased a by the NASA Ames Laboratory developed another set of devices, it called electrocardiogram sensor electrodes placed on the neck caller to detect resistance changes during a call from a private network is responsible for processing the data and validation discourse modes can be detected even silent reading, discourse patterns will be sent to a computer voice sounder, restore caller's voice.

U.S. Defense Advanced Research Projects Bureau for participation in covert operations soldier, a noisy environment or underwater operations staff to provide this technology, but there is always one day civilian version of the product will come out, so that people can plant bite rattle sound, the roar of the machine room, noisy bar or gathering call. Perhaps more importantly, this technology will help people inside the train, cinema or library is not allowed to use mobile phones loud noisy places. Brown has produced a TERC prototype, and electrogram sensing unit prototype developed in 2008 will also be completed.

However, the price of these two systems will be very high because the voice is sent by the computer, so the recipient will hear an artificial voice. In any case, in order to obtain the noise of their own peace and serenity, pay a little more worthwhile. (
