Neil Patwari, a scientist at the University of Utah in Salt Lake City and his colleagues noticed that a person's breathing affects the strength of a wireless signal. That is, thanks to fluctuations in the power of the radio signal, It was discovered relatively by accident: Neil Patwari, a scientist at the University of Utah in Salt Lake City and his colleagues noticed that a person's breathing affects the strength of a wireless signal. That is, thanks to fluctuations in the power of the radio signal, you can find out if someone is in the room. Of course, a person's breathing affects this indicator only when he is in a certain place in the room. While testing the method, Patwari was lying in bed surrounded by twenty inexpensive radio transmitters. They worked at a frequency,
You will still be needed: doctors measure not only the frequency can find out if someone is in the room. Of course, a person's Costa Rica Mobile Number List breathing affects this indicator only when he is in a certain place in the room. While testing the method, Patwari was lying in bed surrounded by twenty inexpensive radio transmitters. They worked at a frequency of 2.4 GHz - the same as any modern wireless router. The strength of the signal was measured four times per second - this is quite enough to detect fluctuations in the strengwaves to affect the radio waves, which became weaker as a result. How can this discovery be applied? Patients who need to measure their breathing rate are forced to lie down with tubes inserted into their noses. If you measure the frequency of breathing with the help of radio waves, you can avoid such inconvenience. However, in most situations, tubes,
Nevertheless, the method has another application - Patwari and his colleagues proved that a transmitter installed behind the walls of a house can effectively track the movement of people inside the room. Chemical composition of exhaled air. Nevertheless, the method has another application - Patwari and his colleagues proved that a transmitter installed behind the walls of a house can effectively track the movement of people inside the room. breathing. After collecting data for 30 seconds, the network of transmitters was able to accurately measure a person's breathing rate. Patwari deduced from this that his chest, which rose with each breath, caused the resulting waves to affect the radio waves, which became weaker as a result. How can this discovery bes will still be needed: doctors measure not only the frequency, but also the chemical composition of exhaled air.
