Abstract: System for the optical examination of human nails that has a camera and a power source or a smartphone provided with a connection to these, a converter connected to the smartphone, which converter contains a housing and a measuring probe, the housing contains a microcontroller, the measuring probe contains at least one macro lens and at least one polarising filter, at least two light sources and a polarising filter film in front of some of the light sources arranged in such a way that the axes of polarisation of the polarising filter films and of the polarising filter are rotated by 90 degrees as compared to each other, where due to the various light sources the system is adapted to use various illumination modes and the smartphone is connected to a neural network. Also, a method for the examination of nails for diagnostic purposes with such devices.

Abstract: The subject matter of the invention is a communication method comprising the establishment of a communication route to a target partner not reachable by direct addressing by by-passing a node blocking the direct connection, further comprising the steps of setting up a TURN server at one or more users of the communication network in response to a definite and pre-granted request or in advance, and implementing the communication route to be established via at least one mentioned TURN server, with the effective mutual authorization management of the users involved in the communication session.

Abstract: Mechanical vibrations induced by the heart of the foetus, together with other vibrations coming from the body of the pregnant mother, are sensed by the at least one electro-mechanical transformer placed on the body surface of the pregnant mother, the vibrations are transformed into electrical signals and processed. The electrical signals are pre-amplified, frequencies including the heart sound of the pregnant mother are removed from amplified electrical signals of the perceived vibrations by active bandpass filtering, the signal level reduction due to bandpass filtering is compensated for by amplification, and the filtered signal is transferred to a device for processing and evaluation. A device suitable for implementing the method, and a computer-readable medium are proposed, the latter comprising instructions to be run on the device, e.g. the smartphone, for processing the measured signals, displaying them visually, showing trends and making proposals to the user based on the processed signals.

Abstract: A method for tracking the movement and trajectory of objects associated with wireless devices, located in a predefined area, wherein transceiver nodes communicating with the monitored wireless communication devices are formed, the objects associated with wireless communication device entering or located in the range of the transceiver nodes are detected by said transceiver nodes and relevant collected data are processed by measuring the strength of the signal emitted by the object during communication by at least two access points, converting the measured signal strength data into a vector set, selecting and filtering out the objects that are communicating but make no movement by evaluating the vector set, and analyzing the movement of the communicating objects changing their place by applying a pre-defined mathematical model. Access points operating according to a small-range “peer-to-peer” (P2P) type wireless communication standard are used as transceiver nodes.
