This paper presents an approach of teleoperation using impedance control for both master and slave manipulators. The 4-channel architecture with impedance control ensures enhanced transparency by appropriately controlling the dynamic behavior between motion and applied forces in the task space of the manipulators on both sides. Performance of the system is improved by using on-line estimation o...
In this paper, some aspects of choosing excitation signals for fast measurement of complex electrical impedance of objects, including impedance of biological tissues, over a wide range of frequencies are discussed. For this purpose, several short-time excitation signals as special cases of chirp signals of near to minimal duration are proposed. The results of analysis and simulation are promisi...
This paper describes the optimization of the measurement time of the impedance frequency response of a vibrating wire sensor for viscosity estimation. The optimization deals with the assessment of the estimated viscosity as a function of the number of measured impedance frequency points as well as the selection of those frequencies. This speed optimization is important to ensure that the viscos...
Cardiac electrical impedance tomography (EIT) signals are affected by myocardial motion. The feasibility of stroke volume estimation using such signals is thus questionable. Results based on a dynamic model show that myocardial motion indeed affects but does not compromise stroke volume estimation.
