The paper considered the implementation of radio frequency identification system of animals for stall milking machines. The proposed system is a part of the information-measuring system of animal zootechnical parameters and process parameters to obtain milk that is used in milking dairy cattle farms departments. A new method for automatic radio frequency identification was developed in realization of which the transponders are not on animals but are mounted in the installation place of the portable milking process control units.

The subject of the paper is vibration monitoring and measurements of the remote object in the pneumatic self-regulating clutch. Data from accelerometer sensor is further processed in dsPIC microcontroller targeted in minimalizing the torsional oscillations in mechanical system. Differential pneumatic flexible clutch is applied for reducing the torsional oscillation phenomena during the regular operation. Conclusions are derived and formulated.

Ograniczenie rezonansowych drgań skrętnych w układach mechanicznych w oparciu o układ mikroprocesorowy jest przedmiotem przedstawionych badań. Układ zawiera akcelerometr wraz z procesorem 16 bitowym ds. PIC.
The article presents the method and algorithm of automatic pointer measuring devices (voltmeter, manometer, metronomes etc.) indications determination in order to determine their dynamic characteristics with the help of web-camera and personal computer. The results of testing and experimental research of developed tool for determining the dynamic characteristics of pointer measuring devices are given. Using this method, the algorithm and the software developed, the process of determining the dynamic characteristics of the pointer measuring devices was automated. The time of recognition and calculation of one measured value for a dual-core processor and webcam with a resolution of 0.3 Mp averages 250–330 ms.
