Measuring electrical phenomena presents a number of challenges for biomedical signal measurement systems. The tiny, microvolt-level electrical pulses that signal a firing neuron or a muscle response are often obscured by high-amplitude noise or accompanied by significant dc potentials. Quite often, the signal of interest is a small, transient pulse that occurs intermittently or only once. In some...

I’m a big fan of the Beagleboard. In fact, when I was involved with the Embedded Systems Conference, we would run classes whereby every attendee would receive a Beagleboard and we’d teach a whole series of classes around it, showing people how to configure it specifically for their application. Now, I’m in possession of the follow-in product, the PandaBoard. The biggest...
Radiation is the real-life boogey man of our times. It lurks everywhere from cell phones and airport scanners to mammograms and other medical devices, and exposure is cumulative, building up over a lifetime. Its effects can be devastating to humans and nature, and FDA is also testing to see what it does to medical devices. The Wall Street Journal reports that researchers in FDA's Silver...
Test strategies are mandatory for every company, whether they are applying diagnostics in the development stage or ensuring quality during manufacturing. As such, it is virtually impossible to have a one-size-fits-all test strategy because there are so many variables and specifics. For example, because of their miniaturized and highly integrated components, circuit board test strategies require...
The healthcare industry has been trying to cut the electric cord since the 1950s when Earl Bakken and Palmer Hermundslie invented the first transistorized cardiac pacemaker with an internal battery. Over the ensuing decades, manufacturers have continued to introduce devices—hearing aids, digital thermometers, defibrillators, nerve stimulators, suction pumps, ultrasound equipment, all manner...
Most of us in the medical device industry are familiar with process capability measurement terms Cp, Cpk, Pp, and Ppk. A small subset of us uses these metrics to generate process validation reports claiming to meet our customers’ capability requirements. But how many OEMs and suppliers have gone to the next level by providing the empirical evidence necessary to prove that the measured data...
