Technical Webinar Series from the Editors of SAE: Cybersecurity for the Life of the Car

In conjunction with SAEConnectivity is making cybersecurity a must-have obligation from initial designs through end of life. Automakers and suppliers have several unique challenges as they attempt to provide connectivity in vehicles that have burgeoning amounts of software that must remain secure and efficient over long vehicle lifetimes. Throughout the industry, there is a race to leverage safeguards used in other industries in ways that meet automotive safety and reliability requirements.

Forging as a Viable Alternative to 3D Printing of Non-Ferrous Metal Parts

3D printing is an additive manufacturing (AM) technology used to build objects layer-by-layer directly from digital data. It has surged in popularity in recent years because it enables fast and flexible product design and prototyping, and can be used to produce small numbers of parts cost-effectively, and create complex parts that are difficult or impossible to make otherwise.

Plastic Bearings Have Staying Power

Plastic bearings are strong enough to outperform and outlast metal in countless applications, however, they are often not considered a viable choice in the engineering community due to the common misconception that plastic is inferior or weaker compared metal. Uncover common misconceptions and learn the true reliability of tribologically-optimized plastic bearings in this whitepaper from the motion plastic experts.

Electropolishing Prepares/Pre-Cleans Parts Properly Prior To Penetrant Testing

It is common, especially in the aerospace industry, for parts that are fracture critical to be Liquid Penetrant Inspected (LPI) prior to installation. Also known as Dye Penetrant Inspection (DPI) or simply Penetrant Testing (PT), this method is used to detect micro-cracks or other defects that could serve as an initiation site for failure. In order to properly execute a penetrant test, the surface of a metal part must be thoroughly clean of any debris, smeared metal, or any amorphous layer that may be hiding a hairline crack thus yielding a false reading.

Will security concerns prevent widespread adoption of wearables and IoT devices?

This week's Question: In the paper "Friend or Foe?: Your Wearable Devices Reveal Your Personal PIN" scientists from Binghamton University and the Stevens Institute of Technology combined data from embedded sensors in wearable technologies, such as smartwatches and fitness trackers, along with a computer algorithm to crack private PINs and passwords. By using data from “accelerometers, gyroscopes, and magnetometers inside the wearable technologies regardless of a hand’s pose,” the researchers could record a hand’s fine-grained movements. The researchers then used a “Backward PIN-sequence Inference Algorithm” to crack the codes.
