A biometric security system which had been developed by specialists of the Scientific Production Association “INFORMATION” was awarded the best innovation product title at the 12th International Exhibition "Guarding, Security and Fire Protection MIPS-2006". The system’s peculiarity lies in utilization of a 3D image of the face for identification of a person. Only within a second and a half, the turnstile equipped by this system would create and analyze such image, and take a decision based on received data – to allow or to prohibit the entrance to the person.
It should be noted that although the device does not look fantastic in outward appearance – it is something like an ordinary “three-fingered” turnstile in the underground or a railway station equipped with a small screen on the board, it is arranged interestingly indeed as it identifies persons not by common, so to say visible photographs or three-dimensional portraits but by a special portrait. As a result, the turnstile can hardly be deceived either on purpose or by accident – neither ordinary masks or guises put on by time would manage to cheat it. The portrait for identification is a special one.
The portrait is made as follows: infrared rays are aimed at the person’s face as if the rays were passed through a multitude of parallel slits (like through a fence or railings). These stripes of shadow and light bend and change on the surface of the face, this being done in a strictly individual way. The camera-recorder (also in an infrared band) captures this striped image and transmits to a PC. A PC, in it’s turn, builds a three-dimentional image by line bends with submillimetric precision, identifies it - compares with the database and opens or closes the turnstile. At the same time, it performs additional tasks – for example, it records the employee’s arrival/departure time.

AI implications: Engineer's model lays groundwork for machine-learning device

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
