Researchers Harvest Energy From Planes
Blog 4/30/2013 23 comments A team of Viennese researchers has come up with a way to harvest energy from airplanes to power sensors attached to a plane’s fuselage that can be used to monitor and collect data on aircraft structural health.
What's the Frequency, Kenneth?
Sherlock Ohms 4/22/2013 10 comments It was OK when a radio station ran a tad above frequency limits. But when other radio operators in the area used the station's frequency as a base, things could get crazy.
Hannover Highlights Industry 4.0
Blog 4/19/2013 11 comments The buzz at the recent Hannover Messe 2013 centered on a German industry initiative called “Industry 4.0” that automation suppliers believe will lead to increasing digitization, networking, and an ability for manufacturers to leverage productivity advances.
Screws Mess With Filter Design
Sherlock Ohms 4/18/2013 3 comments The filter had more rejection at the low end than at the high end since the equivalent capacitance coupling did not provide a transmission at high frequencies.
Video: Man-Sized Jellyfish Robot to Patrol the Seas
Blog 4/16/2013 16 comments Engineers at Virginia Tech have built a jellyfish robot prototype the size of an adult man they say will one day patrol the seas to monitor environmental conditions, study aquatic life, make maps of the ocean's floors, and perform military surveillance.
The Least-Obvious Signals Sometimes Bite You
Sherlock Ohms 4/15/2013 4 comments When is a digital circuit not a digital circuit? When somebody forgot that ultimately everything is an analog circuit, and things like L, R, and C combine in the most insidious ways to derail a design.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
