Classic techniques like videofluoroscopy, stationary manometry, and ambulatory 24 h pH-metry are routinely used in the clinic to study patients with dysphagia, chest pain and reflux-related symptoms.

Here are some tips and information on making impedance measurements on power distribution systems. As you probe around at different locations on the plane you will find that the higher frequency ...

When creating designs, engineers must meet or exceed their objectives for instrumentation and measurement equipment. Having accurate and correct instruments for test and measurement methods and ...

In this interview Dr Tim Ashworth, Applications Manager at Zurich Instruments talks to AZoM about the latest innovations in Impedance Analyzers. Tim explains the key challenges in the world of ...

To determine the effect of acute fluid consumption on measures of impedance and percent body fat (%BF) estimated using segmental bioelectrical impedance analysis (SBIA). Seventy-six healthy, ...

BMW has patented a calibration method for an electrochemical impedance measuring device used to measure an electrochemical cell’s impedance. The method involves connecting the device to an impedance ...

With more than 15 outputs, including skeletal muscle mass and basal metabolic rate, the InBody 770 could revolutionize physical evaluations in the doctorâ s office. Put your feet here. Hold this. Ok, ...

We always enjoy a [FesZ] video and we wonder if the “Z” stands for impedance? That’s the topic of his latest video series: measuring impedance with LTSpice. Of course, he also does his usual thorough ...

Specifics on ac resistance and why ACIR has become a standard measurement for Li-ions. The 1-kHz test frequency for ACIR and why it's the benchmark frequency. Comparing ACIR test vs. electrochemical ...

While ac internal resistance (ACIR) measurements are quite common and somewhat standardized when measuring lithium-ion cells, dc internal resistance (DCIR) measurements are nonstandard and generally ...

As you can see, there are a number of variables and the answer is simply not that straight forward. When conducting amplifier measurements, we tend to be a bit more forgiving with receivers than multi ...

If you’ve done any amount of electronic design work, you’ll be familiar with the need for decoupling capacitors. Sometimes a chip’s datasheet will tell you exactly what kind of caps to place where, ...
