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.
FlexRay spec rev offers back compatibility, lower costs Design How-To 3/15/2012 Post a comment The FlexRay electrical physical layer spec Rev. 3.0.1 has been released and production of second generation transceivers has started. Semiconductor manufacturers have to ensure full device specific functional range in existing applications with a drop-in replacement.
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.
ISO 26262 cuts electronics complexity risks: Pt. 2- Design for robustness Design How-To 3/2/2012 Post a comment Future development and integration of automotive safety functions will strengthen the need to have safe system development processes and to provide evidence that all reasonable safety objectives are satisfied. ISO 26262 provides guidance to reduce these risks to a tolerable level by providing feasible requirements and processes.
Blog Doing Math in FPGAs Tom Burke 24 comments For a recent project, I explored doing "real" (that is, non-integer) math on a Spartan 3 FPGA. FPGAs, by their nature, do integer math. That is, there's no floating-point ...
