Contactless Piston Position Transducer With Axial Excitation
(IEEE, 2017)Existing piston position transducers require either drilling precise hole into the piston bar, or mounting permanent magnets or measuring device inside the pressurized cylinder. We present a new solution for aluminum ... -
Influence of External Current on Yokeless Electric Current Transducers
(IEEE, 2017)Yokeless electric current transducers have compact size, but they are sensitive to external magnetic fields, including those caused by electric currents in their vicinity. It is often believed that this unwanted sensitivity ... -
Off-Center Error Correction of AMR Yokeless Current Transducer
(Hindawi Publishing Corporation, 2017)We present a method of calibration and error correction of the AMR yokeless current transducer consisting of a circular array of eight anisotropic magnetoresistors (AMR) with one feedback compensation loop. The main sources ... -
The effect of conductor permeability on electric current transducers
(American Institute of Physics, 2018)In this paper, experimental works and theoretical analysis are presented to analyze the influence of the conductor permeability on the precision of yokeless current sensors. The results of finite-element method (FEM) fit ... -
Inductance position sensor for pneumatic cylinder
(American Institute of Physics, 2018)The position of the piston in pneumatic cylinder with aluminum wall can be measured by external inductance sensor without modifications of the aluminum piston and massive iron piston rod. For frequencies below 20 Hz the ... -
Evaluation of Objective Speech Transmission Quality Measurements in Packet-based Networks
(2013)This paper presents an analysis of the relation between IP channel characteristics and final voice transmission quality. The NISTNet emulator is used for adjusting the IP channel network. The transmission quality criterion is ... -
Effect of speech activity parameter on PESQ's predictions in presence of independent and dependent loses
(2013)This paper deals with the investigation of PESQ's (Perceptual Evaluation of Speech Quality; also known as ITU-T Recommendation P.862) behavior under independent and dependent loss conditions from a speech activity parameter ... -
Predicting the Quality of Synthesized and Natural Speech Impaired by Packet Loss and Coding Using PESQ and P.563 Models
(2011)This paper investigates the impact of independent and dependent losses and coding on speech quality predictions provided by PESQ (also known as ITU-T P.862) and P.563 models, when both naturally-produced and synthesized speech ... -
Impact of Different Active-Speech-Ratios on PESQ’s Predictions in Case of Independent and Dependent Losses (in Presence of Receiver-Side Comfort-Noise)
(2010)This paper deals with the investigation of PESQ’s behavior under independent and dependent loss conditions from an Active-Speech-Ratio perspective in presence of receiver-side comfort-noise. This reference signal ... -
Impact of Different Active-Speech-Ratios on PESQ’s Predictions in Simulated VoIP Environment
(2009)In this work, we experimentally study how behaviour of the PESQ predictions varies with reference signal characteristic. In particular we investigate the impact of different Active-Speech-Ratios on speech quality ... -
Single-core fluxgate gradiometer with simultaneous gradient and homogeneous feedback operation
(American Institute of Physics, 2012-03-06)A novel configuration of a single-core gradiometer, utilizing both homogeneous and gradient feedback operation, is presented. The fluxgate gradiometer comprises of a standard pick-up/ feedback coil and an additional gradient ... -
Linearity of Pulse Excited Coil-Less Fluxgate
(IEEE, 2009-10)In this paper, we study the open-loop linearity of pulse excited coil-less fluxgate. Narrow current pulses can be used instead of classical sinewave for the excitation of the coil-less fluxgate. This method has shown several ... -
Sensitivity and Noise of Wire-Core Transverse Fluxgate
(IEEE, 2010-02)Fluxgate sensors with cores made of amorphous microwire have low sensitivity due to the small cross-sectional area of the wire. Previous studies with multiwire cores have shown nonlinear increase of sensitivity with number ... -
Advances in Magnetic Field Sensors
(IEEE, 2010-06)The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally ... -
