The increasing request for motor drives with higher power levels is also driving the demand for power modules providing higher currents. The conventional approach to fulfill this requirement is to look for dedicated high current power modules.
Millions of homes and businesses throughout the country are using smart meters which have passive components to thank for powering their “smart” abilities. Passives’ unique qualities are critical to smart meters, and engineers should know about their important role in this rapidly growing industry.
A standard optocoupler provides complete electrical isolation of electronic circuits from input to output while transmitting information across that electrical isolation barrier using infrared light from the phototransistor contained inside the optocoupler.
LCDs have come a long way from the basic passive monochrome segmented characters used in this old clock (Figure 1) to today’s high performance active matrix LED-backlit TFT LCDs and high performance-high contrast passive matrix LCDs.
High-speed backplane connectors continue to be in great demand in supporting next-generation product development in the telecommunication, data networking, data storage, medical diagnostics and other market sectors.
Medical devices present a special and challenging set of requirements for LCD displays. They need to provide high quality images with high contrast, high resolution images and data...
Nearly all vehicles have a chime or speaker on the dashboard instrument cluster for various alert functions. Increasingly, instrument cluster manufacturers are turning to speakers...
It’s that time of year again! No, I’m not talking about Jolly ‘Ol Saint Nick, mistletoe, or trees with stars on top. ‘Tis the season for giving, but also for spoiling ourselves with the latest gadgets, gizmos, toys, and entertainment. We’re never too old to experience the joy of opening presents!
Network security systems are under pressure. You might not be experiencing it yet, but you will soon. The dual challenge of dealing with more attacks at higher speeds threatens to undermine the stability of the most important commercial platforms of the 21st century; namely the Internet.
Automation in the workplace has been rising from the middle of the 20th century, with the introduction of the microprocessor in the 70’s fuelling a massive increase in the use of electronic devices to measure, monitor and control industrial processes.
Ultrasound imaging is one of the most important medical imaging methods due to its safety, cost effectiveness, and real-time capability. Conventional ultrasonic imaging systems use frequencies from 2–20 MHz with a resolution of millimeter level.
With the holidays approaching, what product or technology is on your wish list?
This month's ECN Roundtable question is: “What technology or industry design trend do you feel will impact the power industry the most in the coming year?"
One of the most significant developments in the global optoelectronics and display markets over the past few years has been a complete revolution in the value proposition offered by custom technologies.
The integration of sensors and actuators into encapsulated multi-chip modules creates formidable challenges to characterizing and controlling process pressure. However, a new measurement method developed by Fraunhofer IZM shows that pressure-indicating sensor film can fully characterize the area pressure distribution on the cavity and on substrate surfaces within a mold cavity during encapsulation.
