Method and system for correcting velocity of autonomous vehicle to navigate along planned navigation path
10829117 · 2020-11-10 · ·

Disclosed subject matter relates to field of telematics that performs a method of correcting velocity of autonomous vehicle to navigate along a planned navigation path. A velocity correcting system may receive a velocity for navigating the autonomous vehicle for a selected segment along the planned navigation path and may identify plurality of values corresponding to current vehicle condition while the autonomous vehicle is navigating along the planned navigation path and may determine a counter angular velocity corresponding to current vehicle condition by comparing the plurality of values with pre-stored values. Finally, velocity is corrected by correlating the velocity with counter angular velocity and provided to navigation module for applying the correction velocity. The present disclosure eliminates need for continuous monitoring and steering angle adjustment to align the autonomous vehicle with planned navigation path, thereby reducing power consumption and minimizing jerks experienced by autonomous vehicle.

Method for controlling a change of damping in an artificial joint
10772743 · 2020-09-15 · ·

A method for controlling a change of resistance in an artificial joint of an orthosis, an exoskeleton or prosthesis of a lower extremity. The artificial joint has an upper part and a lower part which are secured on each other so as to be pivotable about a pivot axis, a damper unit is secured between the upper part and the lower part in order to provide a resistance to flexion or extension of the artificial joint, and the damper unit is assigned an adjusting mechanism via which the resistance is changed when a sensor signal of a control unit assigned to the adjusting mechanism activates the adjusting mechanism. The resistance is changed as a function of the position and/or length of the measured or calculated leg tendon and/or the time derivatives thereof.
