Since 2009, K12 Defense has perfected the conversion process, utilizing Moog's linear servoactuator -- which use - in barriers - we introduced to Moog. Moog's design engineers were in our Arizona facility yesterday testing a new device in our wedge plate barriers. We have successfully converted over 50 wedge barrier with our EM+ system for the military and currently place our EM+ system in drop arm, other wedge barriers and gates. See www.k12defense.com
I think the video shows the need for one more feature, a net to catch the debris! The USN used to have a big wire mesh net to protect aircraft on deck from those that were in trouble during landings on a carrier. Modern carriers have an angled flight deck that precludes this requirement.
In the video the leading edge of the barrier is like a knife edge that slices into the moving vehicle. Perhaps a flat plate type front to absorb impact would result in less debris passing the barrier and shearing of the vehicle.
I would be interested to hear what some of the orginial design criteria were.
Chuck, this story is a great example of what good design engineering is all about. Here, Moog is taking a product that's come into increasing usage since 9/11 -- the roadway barrier for security -- and taking it to the next level with an elegant solution that replaces hydraulics with more reliable servo-motor control.
A middle school team from Rochester, Mich., has again nabbed the grand prize in the annual international Future City Competition, which drew students from 37 regions of the United States, as well as from England and China.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
