Control system for quality assurance at manufacturing of instrumentation products

Based on the system approach, the structure of the control system for quality assurance in the manufacture of instrumentation products is proposed. The system contains eight segments located on four levels and covers all types of control used in production. The introduction of a quality control system led to a significant reduction in the defective products. The system is proposed to be used at instrumentation productions.

Keywords: a control, a quality, a system, a product, a technological process.

Hardware-software complex for the low-intensity laser radiation effect on central nervous system evaluation

A hardware-software complex for the evaluation of the response of the central nervous system to the effect of low-intensity laser radiation of the visible range by means of a combination of electroencephalography and simple visual-motor reaction is proposed. Experimental evaluation of low-intensity laser exposure to the central nervous system with the participation of volunteers was carried out. Statistically significant differences in beta-2-rhythm of electroencephalogram between background, a priori and posteriori states were revealed.

Keywords: low-intensity laser radiation, combination of electroencephalography and simple visual-motor reaction, beta-2 rhythm of the encephalogram.

Interrogating Bragg peaks algorithm hardware implementation based on centroid method

The mathematical model implementation of centroid method using to find fiber Bragg gratings peak of reflection is describing through the article. With the help of different Bragg gratings their real reflection spectrum is received, also it`s common features are highlighted. Due to analysis of finding Bragg peaks coordinate mean error dependency from critical parameters of using algorithm, optimal requirements for interrogator designing are formed. Hardware test implementations of resulting algorithm based on microcontroller and FPGA were compared and FPGA variant have been substantiated as a final one.

Keywords: interrogator, Bragg sensor, fiber-optic systems, FPGA, centroid method, spectral analysis.

Bell gas prover at the national primary standard for the units of volumetric and mass gas flow rates GET 1182017

The description of the bell gas prover used as the initial reference installation at the National Primary Standard for the units of volumetric and mass gas flow rates GET 118 -2017 is presented. The technique of reproducing and transfer the units of volumetric and mass gas flow from a bell gas prover to the working standards is considered. The uncertainty budget of gas flow rate measurements by means of the bell prover is estimated.

Keywords: bell gas prover, standard, gas flow rate, calibration test.
