Design a Crankless Engine
Guest Blogs 5/29/2014 27 comments Since the invention of the internal-combustion engine, a Slider Crank mechanism has been used to transfer power from the combustion chamber through the piston to the connecting rod to the crankshaft. Over time, many changes have occurred in the combustion chamber to improve power and reduce emissions.
The Ever-Increasing Value of Modeling
Guest Blogs 5/14/2014 4 comments Engineers should have the necessary mathematical skills to solve numerical problems. Without underestimating the value of solving skills, it will be more beneficial to new engineers if future textbooks devote a majority of their pages to modeling and interpreting the results.
Congress Is Working on an Energy Bill… Again
Guest Blogs 5/14/2014 6 comments Congress is once again working on the bi-partisan Shaheen-Portman bill that will bring forth many energy efficiency measures to add as many as 190,000 jobs and save as much as 12 quads of energy by 2030.
'Necessary & Sufficient' Cover the Safety Level
Guest Blogs 5/7/2014 10 comments There are many basic principles and maxims that engineers can use to solve simple problems. One trick is to ask at least two questions. First, what is necessary to satisfy the requirement? Second, what is sufficient to satisfy the requirement?
Options for Switch-Mode Power Supply Design
Guest Blogs 5/5/2014 1 comment With renewed demand for LED lighting solutions in recent years, there are several options to get started with building a power supply. Consider the following tips, specific to electrical power supply.
Migrating Legacy Devices to the IIoT
Guest Blogs 5/2/2014 3 comments Following on the heels of breathless coverage of consumer Internet of Things (IoT) applications, the Industrial Internet of Things (IIoT) is now also garnering some well-deserved attention.
Fluid Power Is Alive & Well in the Era of Energy Conservation
Guest Blogs 5/1/2014 2 comments Despite what some people think, fluid power systems are capable of very high-performance motion control. A well-designed, closed-loop hydraulic actuator can do things that motors can't do economically and reliably, such as positioning very heavy loads with a 10-micron resolution or better.
With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
If you’re developing an embedded monitoring and control application, then you’ll want to take note of the upcoming Design News Continuing Education Center class, “Embedded Development Using Microchip Microcontrollers and the CCS C Compiler."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
