Using Light to 3D-Print Structures that Remember Their Shapes

A 3D-printed, multimaterial, shape-memory mini-gripper, consisting of shape-memory hinges and adaptive touching tips, grasps a cap screw. (Qi Ge) Engineers are using light to print three-dimensional structures that “remember” their original shapes. The process of 3D printing shape-memory materials can also be thought of as 4D printing, as the structures are designed to change over the fourth dimension — time.

Key Considerations for Powertrain HIL Tes

Safety, availability, and cost considerations can make performing thorough tests of embedded control devices using the complete system impractical. Hardware-in-the-loop (HIL) simulation is a real-time test technique used to test these devices more efficiently. During HIL test, the physical system that interfaces to an embedded control device is simulated on real-time hardware, and the outputs of the simulator mimic the actual output of the physical system. The embedded controller “thinks” it is in a real system. HIL simulation meticulously tests embedded control devices in a virtual environment before proceeding to real-world tests of the complete system. This application note covers recommended best practices for powertrain HIL testing.

Automotive Industry Standards and Trends

In Conjunction with SAE The consumer has reaped the benefits of automotive manufacturers developing new vehicle lines, enhanced features, and safety improvements, all culminating in record sales for the auto industry. While consumers focus on ease of use, driving experience, and safety, manufacturers focus on increased modularity, reusability, and manufacturing efficiency. For manufacturers, this focus means reusing code, components, and technologies to minimize duplication of effort.

Will ground-based delivery robots catch on?

This week's Question: This fall, Starship Technologies, an Estonia-based startup created by two Skype co-founders, will begin testing its autonomous delivery robot in Washington, D.C. Washington is the first U.S. municipality to approve ground-based robots to traverse city sidewalks. Starship aims to bring packages from its fulfillment center directly to customers' homes. Ground-based delivery, Starship’s founders say, is an easier delivery option compared to drones, which require compliance with FAA regulations. What do you think?

Instruments Measure Large-Scale Motion Around San Andreas Fault

Uplift (red) and subsidence (blue) based on GPS data (top) confirm predicted motion (bottom). An array of GPS instruments near the San Andreas Fault System in Southern California detects constant motion of Earth’s crust — sometimes large, sudden motion during an earthquake, and often subtle, creeping motion. The GPS array records vertical and horizontal motion of Earth’s surface. The challenge was to discern the broad, regional tectonic motion from the shorter-scale, local motion.

Introducing Surface Analysis for Automotive Applications

In Conjunction with SAE As the materials used in the construction of automobiles become ever more advanced, the breadth of analytical challenges also increases. The surface or layer chemistry of these materials can be of considerable importance, from understanding the appearance of the paint finish, to tailoring the chemical activity of the catalytic converter in the exhaust system.
