Abstract: The subject matter of the present invention relates to a system for the optical determination of correction planes in rotating elements, used in the process of balancing, in particular in diagnostic devices equipped with a system which has at least one video camera (K), at least one line projector (RL), a monitor screen (M) and a computer (P) which controls individual component elements of the system, wherein the video camera (K) cooperates with the line projector (RL) while projecting a view of the rotating element (EW) on the monitor screen (M) together with an image of a line (L) projected by means of the line projector (RL).

Abstract: The subject matter of the invention relates to a method and system for energy absorption designed for use in particular in exercise apparatuses, and especially in the so-called fitness equipment. The method for energy absorption consisting in that suitable current load values are selected in order to balance the kinetic energy expended by the person performing exercises with the energy absorbed by the system (100) for energy absorption, wherein the value of current load, which is selected by a computer (PC), is dependent on the psychomotor parameters of the person performing exercises. The system (100) for energy absorption is provided with a variable current load circuit (150) connected to an element (S) producing direct current (DC) or alternating current (AC) electric energy, which is controlled by the computer (PC).
