The commercial potential of the system is great: the market for medical applications can reach hundreds of millions of dollars and the size of the security markets is also estimated at hundreds of millions of dollars
The Bar-Ilan Research and Development Company will present during the "Nano Israel 2010" week, which will be held between November 8 and 10 in Tel Aviv, some of the hottest innovations that have come out of the university's researchers' laboratories. For example, a group of researchers led by Prof. Zeev Zalevsky from the School of Engineering at Bar Ilan University developed a system that includes a camera and a harmless laser beam, which if directed at people who are hundreds of meters away from the system, you can hear what they are talking to each other, eavesdrop on phone calls theirs as well as measure their heart rate and even a measurement related to their blood pressure.
Prof. Zalevsky: "One of the advantages of the system compared to voice recording systems is that if there are several speakers at the same time, we can separate the signals and know what each one said and when, unlike in voice recording where we lose direction and all the voices get mixed up." The fact that the system is able to both hear conversations and track medical data indicates that this system can have at least two completely different uses, a security application - mainly in relation to eavesdropping carried out by military and police officials after the enemy or criminals, and a medical application - monitoring patients remotely and without Connect devices to them.
The commercial potential of the system is great: the market for medical applications can reach hundreds of millions of dollars and the size of the security markets is also estimated at hundreds of millions of dollars. The advantage of the security markets, according to Zalevsky, is that although they grow slowly, they are stable and immune to recession, especially if you compare them to the medical markets. The researchers have already built technological demonstration systems, and with the assistance of the Bar-Ilan Research and Development Company, have registered a patent and are preparing for commercialization.

From 2007 that I know advanced communication transmitters of this type have already been installed
The technology is already in use by the general security services, the beta versions (the victims in my opinion are not important at all) are teenagers after the age of 18 on whom the technology is tested. By the way, they must be from an unstable family and with a criminal or drug history, priority of a psychiatric background, a device Advanced communication that transmits through electromagnetic waves the visual thought and everything that happens in the body at a frequency of 850-1200 megahertz (cellular transmission who understands) in the future will be used exclusively for medical purposes and a polygraph test which cannot be lied to, if the person is under hypnosis and has such technology on him it could lead to great destruction
There was a study in one of the institutes in Israel, but all the received signals were above the noise threshold, what did you discover in this study, where is the progress?
Austin, you can't pump mojo with a laser. This was already proven in the famous work of the physicist Prof. Doeg Hanokglu-Pumprenkel-HaCohen, who showed this by way of negation.
They forgot the most important thing and that is that after all the tests they did on them with the "laser"
You can pump them the: "Mojo
And all this from a distance of kilometers.
I wonder who is really behind this story. I thought it was still frozen in geocentric orbit.
Maybe it's time for another movie.
And what about the criminals who are so eager to quote their victims?
Will they also be able to enjoy the fruits of development?
Why only army and police? What is this discrimination?

By the way, the calibration is also not problematic because these are waveforms that are known in advance and whose modulation must be decoded.
Machel
The reliability will depend mainly on the length of the sample, the density of the sequence and the size of the sampled area.
But still - the amplitude of the change depends on the elasticity of the tissues above the blood vessels.
Besides - all the results are also affected by the bending of the hand and other factors.
It may be that all the reservations I raised are negligible, but they can only be neglected if someone has proven their insignificance.
Machel
In my opinion, they also use years and even three lasers with a fixed frequency difference between them in order to obtain a sample from which the data can be derived with reasonable reliability.
Machel
In such a scan, using sensitive and fast sensors, a reflection image of the area is obtained, the changes of which are sampled by tiny color changes on the surface. The continuous computer analysis of the entire scanned area makes it possible to extract the various data from the samples.

When continuously scanning the area of the passage of the artery in the arm from beginning to end. And even if you scan from the chest to one of the arms. When this is done continuously, the blood pressure can be calculated according to the time and amplitude of the change in the artery against the movement of the chest.
It is possible to calculate blood pressure according to the differences that represent the expansion rate of the blood.
Will there be a live demonstration at the convention?
Zarathustra:
I didn't understand how you can get the blood pressure from the sequences in two places.
The optical measurements can only detect movement of external tissues, but the effect of blood pressure on the movement of external tissues depends on different characteristics (such as elasticity) of internal tissues that vary from place to place.
Machel
It is probably a scattering beam as in the hologram technique or alternatively a scanning beam. So checking sequences of two different places in the body may give the calculation for blood pressure.
It's really a shame that they didn't write how it works, because if they've already filed a patent they're actually protected.
I assume that it is about detecting the vibrations of various objects - either by direct measurement of distance or by the Doppler effect. This is a technology that has already been applied in the past (I once heard about the possibility of identifying what is being said in the room by remotely measuring the vibrations of the pane in the window) and it is possible that the entire patent is about the specific focus on the source of the vibrations, but this does not explain the matter of blood pressure (on the other hand, it is a measurement that relates to blood pressure so Maybe it's not about measuring the blood pressure itself, but only about measuring the heart rate - you know - it's really vague).
No word on how it works?
