Monitoring Chest Compression Quality During Cardiopulmonary Resuscitation: Proof-Of-Concept Of A Single Accelerometer-Based Feedback Algorithm
(Public Library Science, 2018-02-14)
Background
The use of real-time feedback systems to guide rescuers during cardiopulmonary resuscitation (CPR) significantly contributes to improve adherence to published resuscitation guidelines. Recently, we designed ...
Enhancing ventilation detection during cardiopulmonary resuscitation by filtering chest compression artifact from the capnography waveform
(Public Library Science, 2018-08-02)
Background
During cardiopulmonary resuscitation (CPR), there is a high incidence of capnograms distorted by chest compression artifact. This phenomenon adversely affects the reliability of automated ventilation detection ...
Experimental Study of the Summation of Flicker Caused by Wind Turbines
(MDPI, 2019-06-22)
Integration of wind energy into the grid faces a great challenge regarding power quality. The International Electrotechnical Commission (IEC) 61400-21 standard defines the electrical characteristics that need to be assessed ...
Flicker of Modern Lighting Technologies Due to Rapid Voltage Changes
(MDPI, 2019-03-01)
The purpose of the present paper is to evaluate the sensitivity of modern lighting technologies to different types of RVCs. In order to do that, 27 modern lampsmainly LEDhave been subjected to real RVCs and their response ...
Experimental Study of the Response of Efficient Lighting Technologies to Complex Voltage Fluctuations
(Elsevier, 2014-07-09)
The replacement of incandescent lamps with more energy-efficient lighting technologies has a direct influence on the way flicker is measured. The International Electrotechnical Commission (IEC) established in the 61000-4-15 ...
Flicker Characteristics of Efficient Lighting Assessed by the IEC Flickermeter
(Elsevier, 2013-10-13)
We present an experimental study of the behavior of modern lighting technologies
under supply voltage fluctuations. Some studies have reported that flicker severity
measurements could exceed the compatibility levels ...
An Alternative Strategy to Improve the Flicker Severity Measurement
(Elservier, 2014-07-12)
The IEC 61000-4-15 standard defines a flickermeter that is universally accepted as the meter used for the objective measurement of a disturbing light flicker. The accurate results provided by the IEC flickermeter under ...
Effect of the sampling rate on the assessment of flicker severity due to phase jumps
(IEEE, 2011)
This paper presents an analysis of the effect of the sampling rate on the calculation by a digital flickermeter of the flicker severity caused by phase jumps. The new edition of the IEC 61000-4-15 standard includes an ...
Influence of carrier phase on flicker measurement for rectangular voltage fluctuations
(IEEE, 2011-11-01)
This paper presents an analysis of the influence of the phase relationship between the fundamental frequency and the rectangular voltage fluctuation on flicker measurements made by the International Electrotechnical ...
