- This paper presents the possibility of using dispersion entropy with a sliding window to assess the stability of machine operation. Attention was focused on the feasibility of using a sliding window and the assessment of the minimum length of the window that produces stable results. The answer to this question is open to all and depends on the complexity of the physics of the phenomenon. Research was carried out first for simple mechanical systems, then for nonlinear systems, and then, in the final part of the research, attention was paid to the real signals describing the displacement of the pan in the bearing. These studies are important in determining the minimum window length to conclude the diagnosis of mechanical systems; the narrower the window, not only reduces the need for computing power, but above all allows a faster response
