Composite repairs cannot be fully checked for quality via visual inspection like conventional repairs. I often wondered how they plan to handle this problem. And well, of course, let a robot do it - they are consistant and have no bad days.
William, I assume that this technology relies on very precise control of the laser to work. There must be some new advances in laser focus or control to make it possible. It is, becuase of the results you mention, not an obvious choice, but someone has figured out how to make it work (werk?).
Wow! Thanks for this, Ann. It's often the obvious solutions that are the most frustrating. The use of dirty, violent abrasive cutting techniques on composites is such an obvious no-no when it comes to disturbing the fiber alignment and potential of layer separation in non-damaged portions of the material. I'm guessing previous attempts to cut fiber/resin composites with a high-power laser resulted in either a puddle of goo or a fire. Kudos to Lasertechnik for developing an appropriate combination of laser power, frequency, modulation, and beam profile for use with composites. This will have wide applications.
Rob, keeping planes in service longer is certainly one of the benefits hoped for from this new technology. The primary benefits, though, are getting them back into service faster, lower cost, more consistent repairs, and techniques that don't shorten a plane's service life by damaging composites during repair (the lack of force or vibration applied to the structure).
That's a very impressive repair system, Ann. Could this potentially extend the life of an aircraft? Seems that would be part of the long-term benefit of this technology.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
