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.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
The US Congress has extended an important tax credit for solar energy, a move that’s good news for future investments in this type of alternative energy and for many stakeholders in the solar industry.
