Modern electric distribution systems typically contain several feedback-controlled parallel inverters that together form a complex power system. Consequently, number of issues related to stability arise due interactions among multiple inverter subsystems. Recent studies have presented methods where the and other dynamic characteristics paralleled system can be effectively analyzed using impedan...

We introduce visual impedance, a new scheme for vision based control which realizes task-level dynamical robot control using a Ims m“sualfeedback system. This method is simply described as applying image features to the impedance equation so that integration of a visual servo and a conventional servo system can be naturally accomplished. With visual impedance, an adaptive motion is obtained for...

Telemanipulation concerns manual operation of a device from a remote location through suitable communication links. In haptics, the communication link is two-way with force feedback from the manipulated object to the human operator. This paper presents a new application of telemanipulation, as used in homecare robotics. For the specific application, a telemanipulation scheme with impedance cont...

Optical nanoantennas have been studied as a means to manipulate nanoscale fields, local field enhancements, radiative rates, and emissive directional control. However, a fundamental function of antennas, the transfer of power between a coupled load and far-field radiation, has seen limited development in optical antennas owing largely to the inherent challenges of extracting impedance parameter...

A bioimpedance detector is developed as part of instrumentation for impedance cardiography. It uses slicing amplifier for increasing the sensitivity for the impedance variation and synchronous sampling for a ripple-free output. The circuit provides digital control of excitation current and frequency used for the measurement. Its operation has been verified using a thorax simulator for detecting...
