Researchers at Bielefeld University have analyzed how reliably AI methods can detect pulse rates from simple video recordings. The technique, known as rPPG—remote photoplethysmography, an optical form ...
In recent years, new testing techniques have been developed to meet the challenges posed by the rapid development of new standards in industries such as semiconductor and communication technology. One ...
Recently, in a meta-analysis of 17 longitudinal studies that evaluated aortic PWV and followed up 15 877 subjects for a mean of 7.7 years, the absolute differences/changes of PWV (in m s −1) have been ...
digiDoc Pulse Oximeter is an iPhone app that uses your camera to measure your heart rate and your oxygen level. Apps that measure your heart rate are a dime a dozen, but this is one that combines ...
Pulse oximeter devices routinely overestimate blood oxygen levels in darker-skinned patients—a racial bias that can trigger downstream health harms for Black individuals, compounding well beyond any ...
Techniques for measuring ultrashort pulses have come a long way in the last 10 years. Marie Freebody speaks to Rick Trebino about the intricacies of working at femtosecond timescales and how the ...
Using a spectrum analyzer for pulsed measurements has always required a careful understanding and knowledge of the parameters of the pulse signal, as well as the subsequent operation of the spectrum ...
