The impedance calculation process is similar to arithmetic operations. The proposed approach combines the advantages of impedance control with hybrid control so that both smooth contact transition and force trajectory tracking can be achieved. The authors concluded that the high characteristic impedance was caused by stiff proximal pulmonary vessels. The diode impedance dependence of the generation frequency was weak and the microwave efficiency remained stable over a wide range of electron beam powers. Figure 4 shows the structure of visual impedance control considered for the case of fictitious forces. Motion planning with virtual impedance method in case of a moving obstacle. Virtual impedance can be defined as the following procedures. The new virtual impedance method is applied to the mobile robot tracking of a given path which avoids obstacles in real time. Additionally, the simulated impedance for the case of neglected eddy currents is depicted. A person with muscular dystrophy could use a programmable impedance to assist with arm movements. In position-based impedance control, the impedance controller alters the position for any force applied to the robot end-point. Our small series show that even without direct impedance data, compliance measurements are possible and reflect vessel modelling under different flow patterns. Tissue impedance has no impact upon the efficiency of stimulation with magnetic fields. But nasal airflow is also influenced by two factors other than the velopharyngeal opening - the overall glottal flow and the impedance in the oral tract. These examples are from corpora and from sources on the web.
