| Feature articles | NTSB: Cause of Virgin Galactic SpaceShipTwo in-flight breakup was human error The National Transportation Safety Board has determined the cause of the Oct. 31, 2014, in-flight breakup of SpaceShipTwo, the Virgin Galactic rocket plane designed to take commercial passengers on a ride to the edge of space. NTSB cited the spacecraft maker's failure to consider and protect against human error and the co-pilot's premature unlocking of the spaceship's feather system, which performs some mechanical gymnastics to slow the vehicle down as it cruises back to Earth.

| Mike Likes: 360-degree display on pressure transducer/switch The TDEPD transducer from Transducers Direct features a unique proprietary design that senses pressure by using a time-to-digital converter (TDC) to measure the duration of a capacitive discharge across the changing resistance in a Wheatstone bridge atop the diaphragm. Clever circuitry splits the signal from the bridge, creating duplicate signals that ensure continuous machinery operation if one half should fail. The all-digital, field-proven design eliminates amplifiers, filters, amplified noise, and signal delays, producing a high-resolution signal without analog variability or noise in the circuit. Plus it has that cool display.

| Engineer's Toolbox: Sandia's new 6DOF vibration table promises different ways of testing It took decades for technology to catch up with the math David Smallwood worked out to control vibration table shakers. Smallwood, a retired Sandia National Laboratories researcher who consults at the labs, knew that shaking in all directions at once was the key to realistic parts testing. Now Sandia is putting the algorithms he developed more than 30 years ago to the test by shaking up nuclear weapon components using a new six-degrees-of-freedom (6DOF) machine.

| Board-level EMI shielding: DIY in minutes ProtoShield sheets from Tech-Etch are depth-etched with a checkerboard pattern for folding, so they can be easily formed into many diverse configurations. In the product-development stage, fully functional shields can be created in minutes with just a pair of scissors and a straight edge for folding. Offered in two sizes: standard (.25-in. squares) and metric (5-mm squares). Both versions are solderable and corrosion resistant due to nickel silver material. Shield prototypes can be directly soldered to the board, or shield clips can be used for easy mounting. Samples available.

| Motion: Powerful new drive electronics for micro stepper motors The new FAULHABER MCST 3601 series programmable motion controller can precisely regulate phase currents from 10 mA to 1.1 A. At the same time, it can be operated with a supply voltage that can vary between 9 VDC and 36 VDC. Since the controller is designed as a test electronics system, users can adopt the predefined architecture according to their requirements and integrate the components in the platform of their specific industrial application. Furthermore, the MCST 3601 series can actuate stepper motors in micro stepping mode: up to 256 micro steps per full step. Perfect for applications in optics.

| Materials: Plastics that resist chemical attack from hospital disinfectants RTP Company engineers tested a number of polymers for damage resistance to hospital cleaners and disinfectants, and then optimized the best-performing alloy. Known as the RTP 2000 HC series, these thermoplastic compounds can help solve cracking issues in existing devices and open a new realm of possibilities for the design of hospital equipment and plastic housings that require frequent disinfection, such as mobile ultrasound and x-ray machines, enteral feeding devices, drug infusion pumps, blood filtration equipment, and more.

| Lean Thinking: Redefining work "We need to think about redefining work," says John Shook, Chairman and CEO, Lean Enterprise Institute. "You may be able to create wealth through a variety of business models or ways of thinking. But if you want to create real value, and jobs that value people, you must think hard about how your people are working every day."

| Wheels: Stealthy mortar system to boost speed, accuracy, enhance Soldier safety In certain battlefield conditions, such as the mountainous terrain and unimproved roads of Afghanistan, large-caliber indirect-fire weapon systems lack the mobility and maneuverability required to successfully execute an assault. To resolve this concern, engineers at Picatinny Arsenal are developing a revolutionary weapon system called the Automated Direct Indirect-fire Mortar (ADIM), which can be fired while mounted on a light tactical vehicle such as the HMMWV (High Mobility Multipurpose Wheeled Vehicle) or its replacement.

Improve your cost-estimating process Explore this quick tutorial preview and learn about some of the features and benefits inside Costimator with 3DFX. This 60-second presentation explains how quick and easy it is to read 3D CAD files and instantly import part features and dimensions for estimating and quoting in Costimator. The new 3DFX automated feature recognition (AFR) add-on to Costimator V14 recognizes CAD features and their parameters from solid models and gives estimators complete control over features they "extract" and import into Costimator for estimating. This is a powerful, long-awaited update to this software tool.
