The advanced multispectral method is developed for formation and recovery of the image of a hypodermic on the basis of function of a detuning and its algorithm realizing. The method reduces distorting influence of change of characteristics of skin on image formation. Use of function of a detuning allows to make processing without observance of rigid requirements to the accuracy of a choice of lengths of waves on which images and, respectively, providing a preset value of the relation of values of optical thicknesses of skin are formed.

With the increase in the coefficient of friction is a growth of the torque transmitted by the lead pair of friction of the main friction, reducing torque is transmitted by the slave pairs of friction friction core group and a couple of extra friction of the friction. Load transfer in the adaptive friction clutches reduces spacer force and accelerate the growth of the torque transmitted by the friction pair of the main driving frictional group.

The coefficient of friction, whereby the total nominal load adaptive clutch transmitted only the leading pair of friction friction basic group is less than the maximum value, which may take the coefficient of friction in actual operation of the coupling. Appearance and an increase in the strength of the spacer when the external load and increasing at an elevated value of the friction coefficient begins at a certain minimum value of the external load, which depends on the total number of pairs of friction of the friction core and the gain. The dependences of the distributions of the torque between the lead pair of friction friction main group and driven friction pairs of basic friction and friction pair of extra friction.

In a modified version of the adaptive clutch size of the spacer strength decreases due to a reduction of torque, which transmits the additional friction group, including, for the maximum value of the friction coefficient. Therefore, to save the value of the brace force is necessary to increase the ratio usileniya.Predlozhena concept modernized version adaptvnoy clutch with a combined feedback based on the formalization of the distribution of power factors for the closure of the main steam friction of the friction and more friction groups, allows you to simplify the design of the coupling compared to the base case
