Big-rig truck drivers will soon get a big nix on their habit of running their engines all night long to power their in-cab conveniences such as heating, cooling and entertainment. Without running the engine, their batteries get depleted overnight. So Maxwell Technologies of Detroit and Alcoa AFL Automotive of San Diego are merging their technologies to develop an efficient engine-starting system that will quickly jump a cold engine. “The AFL-Maxwell cold starting system, with its ultracapacitor pack, will provide what amounts to an on-board jump-start capability,” says Allen Zwierzchowski, president of Alcoa’s Worldwide Components AFL Automotive.
According to Zwierzchowski, fleet owners incur significant costs due to vehicle downtime and jump-starting stranded trucks. The Maxwell-AFL ultracapacitor is designed to relieve batteries of the demanding short-duration high-current loads experienced during cold-starting and engine. The ultracapacitor is also built to improve overall system performance and reliability while extending battery life and reducing battery maintenance and replacement costs.
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.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
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.
