3D is growing in the inspection of automotive assemblies, either using 3D cameras, or stereo configurations of multiple 2D cameras such as the 2 megapixel high-resolution Marlin camera.

I'd be interested to hear about what, if any, development work is required on the software side to create programs which can analyze the 3D data coming out of the camera, so as to identify defects as they pass under the camera, as well as the quantitative experience of 3D versus 2D. As you allude to, probably the biggest positive impact is that 3D cuts down the inspection time needed to verify that complex assemblies are defect free.
Seems like a logical move to deply 3D cameras on factory floor inspections. Another new tool gaining mileage for monitoring quality on the factory floor is the iPad. I've heard about companies outfitting production floor workers with the tablet so they can roam the factory floor and inspect for problems, using the built-in camera and location tracking capabilities to pinpoint trouble spots and send real-time images of faulty equipment back for evaluation and troubleshooting.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.

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
