Engineers have shown that a technique to measure heart rate via Wi-Fi signals is effective even with the lowest-cost devices ...

Researchers have developed a time-domain single-pixel imaging technique to speed the measurement of ultrafast pulses in infrared and far infrared wavelengths. When we look at an object with our eyes, ...

Sources of attosecond-duration light pulses provide the fastest time resolutions available today for observing ultrafast phenomena in atoms, molecules and condensed matter. The measurement of such ...

Imagine tracking your heartbeat without strapping on a smartwatch or touching any gadget, just by sitting within range of your Wi-Fi. This is made possible with Pulse-Fi, a system recently unveiled by ...

Generating ultrashort laser pulses that last a few femtoseconds is a highly active area of research that is finding applications ranging from micromachining to eye surgery. For optimum results it is ...

A few weeks back, we reported on a research group that figured out how to measure heartrate using perturbations in WiFi ...

August 20, 2013. Anritsu has expanded its VectorStar family of vector network analyzers (VNAs) with the introduction of the MS4640B Series. Featuring a number of new measurement capabilities, ...

Today, in the assessment of cavernous artery blood-flow, the most commonly used technique is Doppler ultrasound velocimetry (continuous, pulsed, color-coded or power), which is often considered as the ...
