A parallel LC filter has impedance that's theoretically infinite at its resonant frequency. You can exploit this characteristic to decouple a voltage generator from its load. Doing so lets the generator drive any load.
Every so often, an article comes along that discusses technology replacing people. Usually, these articles are doomsday stories about how we'll all lose our jobs to robots and online services. The counter argument, often from the other side of the political spectrum, is that automation increases profits, which companies then invest into making new jobs, ...
In some of my previous blogs, I talked about integration of more wireless connectivity to vehicles, and the evolution of RF connectors used in vehicles. In this blog, I turn to data connectivity within the vehicle other than RF.
Last week, a colleague of mine, Karen Field, posted a comment on UBM's internal website about her father, a former auto mechanic. He told his children, "Buy a car with as little electronic content as possible." Cars today can't run without electronics, and more is on the way.
We've all lamented at times, "I wish they made such-and-such," or "I wish we had something that did this." Usually, the item that we wish for is a product, feature, or even a small widget that would make things easier. Other times, it's something outside the realm of possibility as we presently know it, such as time travel (I'm not saying here that it ...
When I was editor of Design Ideas, I probably saw more circuits for charging and monitoring batteries than for any application except LEDs. This week, I present circuits that charge batteries, limit current, monitor battery health, and measure discharge time.
Father's Day in the US is this Sunday, June 16. While researching the history of Father's Day, I discovered that June 16, 2013, is also Father's Day in India. I seem to remember always observing Father's Day, but it apparently didn't become an official day in the US until 1972.
DesignCon, the conference for engineers who design and test the highest-speed electrical and optical communications links, has issued a Call for Abstracts for DesignCon 2014. As in previous years, DesignCon 2014 will have 14 technical tracks. You can find a table listing them at The Call Has Been Made.
Welcome to the introductory blog on medical-device connectivity. I'll focus on connecting medical devices in the patient care environment to systems and applications that make use of information for patient care management. Yet, this focus will be more on the physics of medical device connectivity -- the actual extraction of data from these medical devices.
Many of us own soldering irons or soldering guns. In fact, I have two Weller soldering guns that have incandescent bulbs to illuminate the work area. But, these lights tend to shine on a wide area. My two soldering irons (also Weller), have no lights at all.
