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.
The paper proposes a new electropulse apparatus for processing natural raw materials. The temperature of the crushing-and-reducing assembly of an electropulse plant is found. The results of ore crushing are presented and optimal engineering factors are offered. The elemental analysis of the test material is obtained. It is reported that the electropulse processing at the reduction stage made for significant increase in the content of non-ferrous and rare metals.
