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.
Vishay TL3 tantalum chip capacitors Product News 3/15/2012 Post a comment Vishay's new TANTAMOUNT surface-mount tantalum molded chip capacitors offer DC leakage current as low as 0.005 CV, a capability that enables system designers to extend battery run-time in portable devices.
We teardown a Chevy Volt (exclusive videos) Design How-To 3/12/2012 2 comments 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.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
