The beating of the heart is often recorded via sound or simply with touch - but there's also another interesting and somewhat lesser known option - light. An infrared emitter/detector pair can be used along with a programmable microcontroller, to effectively visualize the effects of the human body's hardest-working muscle
In the industrial environment, touch panels, or touchscreens, facilitate operator input in a very simple, yet reliable, way. As touch input-based handheld and mobile devices enter more industrial applications – such as portable flow controls and handheld terminals for field testing – companies need to protect and extend their investment.
Many general-purpose signal processors are acceptable for industrial applications based on their computing performance and baseline connectivity features. However, there are important peripheral enhancements that can significantly upgrade the processor’s capabilities for more demanding industrial systems.
It's hard to believe, but the holidays are in full swing and many of you are starting to decorate your homes. Those of you who started around Halloween are probably feeling pretty smart because you got your decorating done while the weather was nice.
Linear Technology announces the LTC3108, a highly integrated step-up DC/DC converter designed to start-up and run from extremely low input voltage sources such as thermoelectric generators (TEGs), thermopiles and small solar cells. Its self-resonant topology steps up from input voltages as low as 20mV.
Holidays in New York City are beautiful. The lights, the people, the excitement. However, Christmastime in the city is also a constant reminder that you have gifts to buy for people, regardless of your particular secular rationale. For the style-conscious, the E Ink Digital Calendar Watch from Phosphor is both attractive and cutting-edge...

Cree, Inc (Nasdaq: CREE), a market leader in LED lighting, and Ningbo Liaoyuan Lighting Co., hosted the 2009 LED Lighting Fixture Promotion Conference last week in Guangzhou, China. The conference featured government officials and leaders from city street lamp management offices.
Leaders of the Commonwealth countries called Saturday for a legally binding international agreement on climate change and a global fund with billions of dollars to help poor countries meet its mandates. The 53-nation meeting was the largest gathering of international leaders before next month's global climate summit in Copenhagen.
I don't know about you, but about the last thing I want this year for the holidays is another mustard-yellow sweater. Sure, it's nice to have some extra-warm clothes stashed in the top drawer of the dresser this time of year, but I'm clearly maxed-out in the
I'm so tempted to track down your home address via your IP address and come over there and punch you. Of course it's worth it. What else are you going to do?
That California and Texas still lead the United States in generating renewable energy probably is no surprise. But, NREL's 2009 State of the States report shows that several smaller states from Maine to Louisiana to Utah are closing the clean energy gap, confirming that every state has...
Norway opened on Tuesday the world's first osmotic power plant, which produces emissions-free electricity by mixing fresh water and sea water through a special membrane. State-owned utility Statkraft's prototype plant, which for now will produce a tiny 2-4 kilowatts of power or enough to run a coffee machine, will enable Statkraft to test and develop the technology needed to drive down production costs.
Some of my co-workers are at the Embedded Systems Conference this week in San Jose and they're presenting a session on how smart kids are these days. I mused on the subject and realized that educating children to eventually take my job is not the best idea. Seriously kids, go watch TV.ps....
It's nearly Thanksgiving, the second of the "big" holidays that break up the last three months of the year. One of the most common family traditions is listing the things for which we are thankful. These are mostly items such as "family," "friends" or "good
Last week, the Environmental Protection Agency announced its new green homes Web site. The site provides an interactive experience that helps people
Nowadays security is the key to whether it is in homeland defence, or security monitoring of parking lots or buildings. Surveillance systems are either passive systems using IR cameras, or active systems based on infra-red light sources, which are invisible for human eye...
With the holidays approaching, what product or technology is on your wish list?
The Center for Disease Control commissioned a survey to find information about computer game players. The result: I'm furious. I paid taxes that funded this survey? They could have just called me.Learn more about the survey here.
So GeekDad, a super awesome blog from Wired, found my vids and wanted to interview me. Here are my responses:
So, I was told it takes up to 24-48 hours to change the site to the new server and it is still updating the redirect. BUT, I wanted to deliver what was promised. Check out the new site here:www.anengineeringmind.automatedtestblog.com/Soon, you will be able to just type anengineeringmind...
Increasingly, the biggest challenges designers of consumer electronics products face have less to do with performance or feature-richness, and more to do with ease of use and simplicity. This is especially true in entertainment networking, where multiple technologies currently vie for adoption, and consumers have made it clear they want a simple solution, right out of the box.
This week, John discussed buying clean electricity from your utility. If you can't set up a small renewable energy system of your own, buying clean electricity is a great way to support the use of renewable energy.
The exterior skin of NREL's newest building will do more than keep the weather out. The concrete panels actually will be part of the Research Support Facilities' heating and cooling system. It's an old idea brought back to life in the name of energy efficiency.
Driving hydrogen fueled SUVs for 431 miles per fill-up is no longer a California dream. Researchers from NREL and Toyota recently completed a 331 mile round trip drive between Torrance and San Diego in two Toyota Highlander Fuel Cell Hybrid Vehicles. And, with the fuel remaining, those...
