Magnetic induction pneumography: a planar coil system for continuous monitoring of lung function via contactless measurements

open access: yesJournal of Electrical Bioimpedance, 2010
Continuous monitoring of lung function is of particular interest to the mechanically ventilated patients during critical care. Recent studies have shown that magnetic induction measurements with single coils provide signals which are correlated with the ...

Reset dynamics and latching in niobium superconducting nanowire single-photon detectors [PDF]

open access: yes, 2010
We study the reset dynamics of niobium (Nb) superconducting nanowire single-photon detectors (SNSPDs) using experimental measurements and numerical simulations. The numerical simulations of the detection dynamics agree well with experimental measurements,

A practical approach for magnetic core-loss characterization [PDF]

open access: yes, 1995
A practical approach for magnetic core-loss characterization up to a few megahertz is presented. An error analysis is for the first time performed, revealing that corrections are needed to compensate for errors introduced by the extra phase shift ...

A giant magneto-inductive sensor for measuring high rotational speed of brushed and brushless direct-current motors

open access: yesAIP Advances, 2019
There is a paucity of research on measurement of high rotational speed of direct-current motors using giant magneto-inductive sensors. In this work, measurements of high rotation-speed of brushed and brushless direct-current motors were realized by using
