a Virtual Instrument for the measurement of ieee std 1459 2000 power quantities
IEEE Transactions on Instrumentation and Measurement, 2008Co-Authors: Antonio Cataliotti, Valentina Cosentino, S NuccioAbstract:In this paper, the authors present a PC-based Instrument for the measurement of electrical-power quantities defined in IEEE Std. 1459. The Instrument is based on a time-domain technique for the detection of the fundamental and harmonic components of voltages and currents. The time-domain strategy was originally developed by the authors for three-phase, three-wire systems. In that paper, the strategy had been extended to both three-phase, four-wire and single-phase systems. Simulation tests were carried out to assess the uncertainty contribution of the proposed strategy in the absence of the measurement transducers. Moreover, the accuracy of the PC-based Instrument with its transducers was evaluated; the experimental tests were carried out by using a power calibrator.

Instrumentation and Measurement Technology Conference, 2005Co-Authors: Antonio Cataliotti, Valentina Cosentino, S NuccioAbstract:In this paper the authors present a PC-based Instrument for the measurement of the electric power quantities defined in IEEE Std 1459, both for single phase and three phase systems. The Instrument is based on a time domain technique for the detection of fundamental and harmonic components of voltages and currents. The time domain strategy is developed for both single phase and four wires three phase systems. Accuracy characterization is performed considering the presence of voltage and current transducers by means of a power calibrator

a Virtual Instrument for measurement of flicker
Instrumentation and Measurement Technology Conference, 1998Co-Authors: S Caldara, S Nuccio, C SpataroAbstract:All types of fluctuations of the rms voltage in power systems may be assessed by using a "flickermeter" which complies with the specifications given in IEC-EN 60868. In this paper, a digital flickermeter is presented based on the implementation in the frequency domain of the weighting filter block of the eye-brain simulation chain. The Virtual Instrument, implemented with an acquisition board inserted into a PC and with a software developed with the LabView tools, samples the voltage and furnishes the instantaneous flicker level and other severity coefficients. Results of simulated and actual data are reported to validate the performance of the developed flickermeter.

a Virtual Instrument to standardise the calibration of atomic force microscope cantilevers
Review of Scientific Instruments, 2016Co-Authors: John E Sader, Riccardo Borgani, Christopher T Gibson, David B Haviland, Michael J Higgins, Jason I Kilpatrick, Paul Mulvaney, Cameron J Shearer, Ashley D Slattery, Peranders ThorenAbstract:Atomic force microscope (AFM) users often calibrate the spring constants of cantilevers using functionality built into individual Instruments. This calibration is performed without reference to a global standard, hindering the robust comparison of force measurements reported by different laboratories. Here, we describe a Virtual Instrument (an internet-based initiative) whereby users from all laboratories can instantly and quantitatively compare their calibration measurements to those of others—standardising AFM force measurements—and simultaneously enabling non-invasive calibration of AFM cantilevers of any geometry. This global calibration initiative requires no additional Instrumentation or data processing on the part of the user. It utilises a single website where users upload currently available data. A proof-of-principle demonstration of this initiative is presented using measured data from five independent laboratories across three countries, which also allows for an assessment of current calibration.

digital signal processing by Virtual Instrumentation of a mems magnetic field sensor for biomedical applications
Sensors, 2013Co-Authors: Raul Juarezaguirre, Hector Vazquezleal, Saul M Domingueznicolas, J. Andrés Tapia, Elias Manjarrez, Eduard Figueras, L A Aguileracortes, A L HerreramayAbstract:We present a signal processing system with Virtual Instrumentation of a MEMS sensor to detect magnetic flux density for biomedical applications. This system consists of a magnetic field sensor, electronic components implemented on a printed circuit board (PCB), a data acquisition (DAQ) card, and a Virtual Instrument. It allows the development of a semi-portable prototype with the capacity to filter small electromagnetic interference signals through digital signal processing. The Virtual Instrument includes an algorithm to implement different configurations of infinite impulse response (IIR) filters. The PCB contains a precision Instrumentation amplifier, a demodulator, a low-pass filter (LPF) and a buffer with operational amplifier. The proposed prototype is used for real-time non-invasive monitoring of magnetic flux density in the thoracic cage of rats. The response of the rat respiratory magnetogram displays a similar behavior as the rat electromyogram (EMG).
