"Today's MEMs designers face a difficult design hurdle: Combining fabrication process information with 2D-mask geometry for creating 3D structures," says Victor Yarberry, principal member of Sandia National Lab's technical staff. "The fundamental problem is that a 2D mask does not reveal the true 3D structure." For addressing this problem, the Lab's scientists created SUMMiT (Sandia Ultra-Planar Multilevel MEMS technology) software. Sandia is making the software's source code available. The software's 3D model generator applies fabrication steps to 2D masks for creating a solid model. "Currently, there are no commercial tools that can model the entire SUMMiT process, which includes a wet undercut etch followed by a conformal deposition," says Yarberry. The new code uses algorithms for providing representations of conformal depositions on the underside surface. "These steps allow creation of important mechanical features, such as gear hubs and hinge points by the designer," he says. He notes that MEMs devices are being designed into computer disk drives, optical communication switching devices, and accelerometers for automotive air bags.

United Launch Alliance will fly 3D-printed flight hardeware parts on its rockets starting next year with the Atlas V. The company's Vulcan next-gen launch vehicle will have more than 100 production parts made with 3D printing. The main driver? Parts consolidation and 57% lower production costs.
The new small-form-factor EZ-BLE PRoC (Programmable Radio on Chip) module is a derivative of the existing PRoC BLE Programmable Radio-on-Chip solution. The EZ-BLE PRoC module integrates the programmability and ARM Cortex-M0 core of the PRoC BLE, two crystals, an onboard chip antenna, a metal shield, and passive components.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
