POINTER – a device designed for firefighters, rescuers, search robots and all those who are forced to delve into a confined space with an unknown and volatile topology. For example, a burning building with collapsing ceilings or the intricacies of pipelines, some of which are broken. Wherever vision, hearing, radio and GPS signals are useless.
The principle of operation of POINTER is based on the processing of quasi-static electromagnetic fields, which are full of shortcomings, as a tool for communication. But in contrast to radio waves, they are not shielded by the walls of buildings, do not lose power when passing through various materials and have a small range of action. That is, if a person with a POINTER set on his back enters a bunker or a skyscraper , the operator will encounter a minimum of interference, tracking his movement.
The merit of Dr. Darmindra’s group Arumugam is not in the idea of curbing quasistatic electromagnetic fields, but in developing mathematical algorithms for analyzing their behavior. This is the most complicated layer of new technologies with attractive potential. For example, a small rate of signal change, in comparison with GPS, allows to fix not only the location of the object, but also the process of changing its orientation in space.
As a result, the group commander’s screen is not a point, but a complex image, from which one can understand whether a person is sitting or lying. And if he lay down, he crawls or stays in place. And make an indirect conclusion about his state of health in order to make the right decision. This technology is useful to the military, and physicians, and builders, and developers of space robots. And if NASA achieves the desired miniaturization and cheaper devices, we will get a whole new class of sensors of wide application.
