As the hearing continues the focus is on the type of epoxy used in the ceiling panels that collapsed in the Big Dig tunnel last summer.
Following a presentation outlining the fundamentals of epoxy. The conversation has now turned to the difference between "fast set" epoxies and standard epoxy. The epoxy used in the tunnel in question was a fast set epoxy. And the question now is whether in effect the wrong "glue" was used and was this information availalbe to the designers, project managers and suppliers. It’s a question of the load values in terms of the type of epoxy used, along with the long-term characteristics of fast set epoxy and the safety value factor of this type of adhesive in this type of structure. Was the epoxy used appropriate for the loads it was expected to hold?
Safety networks have become more complex, and have actually become simpler and easier to deploy for plant operators. This slideshow highlights developments in plant safety with an emphasis on integrated safety networks.
As the MEMS industry spans a myriad of industries and markets, the future of MEMS in consumer electronics will enable a myriad of functionality, applications, and personalization.
The Nest is a sleek-looking digital thermostat which can actually "learn" its owners' schedule and then continue to regulate temperature to suit the user's preferences and patterns.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
