Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation, 2015
For the existing measurement methods of residual voltage which can't turn the power off at peak voltage exactly and simultaneously display waveforms, a new residual voltage detection method is put forward in this paper. First, the zero point of the power supply is detected with zero cross detection circuit and is inputted to a single-chip microcomputer

Voltage-sensing residues in the S4 region of a mammalian K+ channel

Nature, 1991
The ability of ion-channel proteins to respond to a change of the transmembrane voltage is one of the basic mechanisms underlying electrical excitability of nerve and muscle membranes. The voltage sensor has been postulated to be the fourth putative transmembrane segment (S4) of voltage-activated Na+, Ca2+ and K+ channels.

Estimation of residual common mode voltage in floating voltage measurement with differential voltage probe for high voltage power electroincs circuit

2018 IEEE CPMT Symposium Japan (ICSJ), 2018
This paper evaluates the influence of common mode voltage in the floating voltage measurement with differential voltage probe, and proposes the procedure to compensate the influence of common mode voltage. The measured residual common mode voltage superimposed on differential voltage probe output is compensated with the measured residual common mode ...

Effect of Electron Traps on Residual Voltage in Chalcogenide Photoreceptors

Japanese Journal of Applied Physics, 1982
The effect of electron traps on the residual voltage in chalcogenide photoreceptors is discussed. In order to cancel hole traps in these photoreceptors and to decrease the residual voltage, it is useful to introduce electron traps. It is seen from numerical calculation that, in the case of uniform distribution of the normalized electron trap ...

Study on the Polarity of Residual Voltage in Polymeric Insulating Films

Japanese Journal of Applied Physics, 1986
Residual voltages were measured for seven kinds of polymeric insulating films with brass or evaporated silver electrodes at room temperature. When the circuit was opened at the cathode side, the negative residual voltage was always observed in polyethylene terephthalete (PET), polycarbonate (PC), polystylene (PS) and polypropylene (PP) regardless of
