High-voltage surge stoppers ensure reliability during power spikes
Design How-To 3/29/2012 6 comments
In automotive, industrial, and avionic applications, high-voltage power supply spikes are commonly encountered. The electronics within these systems must not only survive surges, but in many cases also operate reliably throughout the event—and devices charged via automobile power points (lighters) must also be protected.

What makes a Chevy Volt tick (and whirr and hum) is revealed in these videos where the car was taken apart over three days—quality, ruggedness, and modularity for incorporating future technology are apparent.
Transmitter/receiver pair serves as antitheft alarm
Design How-To 3/8/2012 3 comments
Simple circuit consists of a transmitter/receiver pair that functions as an automobile antitheft alert system. When the vehicle leaves the area, this circuit sounds an alarm because the distance between the transmitter and receiver increases and the received power level falls below a predetermined threshold.
EIS simplifies battery measurement and characterization
Design How-To 3/5/2012 3 comments
Electrochemical impedance spectroscopy (EIS) is increasingly important for measuring and characterizing batteries and other electrochemical systems. This non-invasive measurement method can be exploited not only in modeling energy storage such as batteries and fuel cells, but also in basic battery research and diagnostics.
