If you’ve ever felt that heart-in-throat, hyperventilating, out-of-body feeling of not being able to find your kid in a park or after school, only to have her reappear after a few seconds of mind-numbing panic, you can understand why someone would want to invent a Lojack for children.
When Motor Trend announced an electric car was their pick for Car of the Year, something tells me you could have heard a pin drop in the car world. An electric car? They must have rigged the vote.Well, my friends, I hate to break it to you, but Consumer Reports just agreed with Motor Trend,
The battery fuel gauging system is the component responsible for determining the energy remaining in the battery. In this article, a battery fuel gauging system used in single-cell applications is described. This is followed by a discussion of the various algorithms used by the fuel-gauging system to determine battery capacity along with the pros and cons of the algorithms.
Lithium chemistry is preferred for long-life applications because its intrinsic negative potential exceeds that of all other metals. Lithium is the lightest non-gaseous metal, offering the highest specific energy (energy per unit weight) and energy density (energy per unit volume) of all available battery chemistries.
Most cottages in the countryside are heated by burning wood in a simple stone hearth. The desired heat is controlled by the feeding of wood. Today computers manage heating systems in large buildings and the boiler has become almost secondary. A similar trend is evolving with batteries.
Here at ECN, we often talk about alternative energy options. Sometimes it’s solar power, other times wind power, and occasionally we dabble in the world of electric cars. But there is one energy option we’ve been sorely remiss in covering: pee-power.
Water utilities worldwide are increasingly migrating to wireless to enable automated meter reading (AMR). By 2016, annual wireless water meter shipments will hit 10 million worldwide, with the majority going to North American utilities, IMS Research predicts. In 2010, North American utilities accounted for 70 percent of the $500 million global wireless water meter market, IMS says.
Were you aware of the fact that you waste one week per year sitting in traffic? One week per year. That is 7 days, 168 hours, 10,080 minutes, stuck in traffic. Not only is it a huge waste of time, breathing in the exhaust fumes while you sit and mentally-fume can actually be dangerous to your health
Experts in the power industry weight in on the question: What must designers of portable devices do to keep pace with increased power and performance demands? In their responses the industry experts talk about the future of portable devices and the design changes necessary to power them.
On the cusp of Veteran’s Day, I’m reminded that a disproportionate number of our friends and colleagues served in the military. And that makes me proud to work in this industry. ECN — and her parent company, Advantage Business Media — is no exception. You can’t swing a dead cat (or give a resounding Hoooah!) without hitting a veteran.
In October, we asked you for your words of wisdom for a brand-new design engineer and boy, did you guys have advice in spades. The responses we received were so good in fact, we’ve decided to open up our December Roundtable to our faithful readers in hopes that you can offer more words of wisdom.
One of the most important factors in the purchase of home appliances is how the product looks and what high-end features it supports. With today’s highly integrated System-on-Chip (SoC) processors, designers can introduce not only a new UI based on capacitive sensing but also incorporate other system functions to lower system cost and save board space.
The 25th International Trade Fair for Electronic Components, Systems, and Applications (i.e., electronica 2012) starts next week (or now, depending on when you see this), so ECN thought it fitting to interview one of the leading OEM vendors, Standex Electronics about industry trends, especially as it relates to sensors.
Harking back to the good-old-days, before social media, before texting, before mobile phones – all the way back to when we (not me literally) received news from the wireless (radio), this new-fangled invention came along called the TV and sat down in living rooms everywhere.
The idea of using wind to create energy isn’t exactly new. The first examples can be traced back to 200 B.C. in Persia – a creation of Heron of Alexandria. That particular device simply harnessed the wind to power a machine, so a case could be made that the first real windmills were built a little bit later, in the 7th century in Sistan, modern day Iran.
