Researchers Harvest Energy From Planes
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
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
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

Post-lunch power surges caused a world of problems at a high-tech defense firm.
Video: Man-Sized Jellyfish Robot to Patrol the Seas
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
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.
Forget doping. Officials at this year’s Tour de France are looking for a very different form of cheating -- electric motors hidden inside the seat tubes of bicycles.
Through my first-hand experience at MEMS Engineer Forum in Japan, it’s clear to me that the IoT is real and that the Japanese are amply prepared for it and are executing on it today.
A new fixings and fastening system for assembling structural, load-bearing composite components promises 54% better adhesion, plus less weight and better mechanical performance than current composite fixing designs.
A cross-disciplinary team of scientists at Harvard University have invented a bionic leaf that can turn solar energy into fuel.
Following in the tracks of the fabled rocket plane programs of the 1940s, NASA engineers are now laying the plans for a new twist on the future of aviation -- a battery-powered airplane.
