Salakazi Racing’s KTM nitro methane motorcycle/dragster does the quarter mile in 6.7 sec, with a terminal velocity of 196 mph. One key for reaching these speeds is an automatic three-disc, four-stage clutch fitted with a Proworx digital controller. That controller is pre-programmed for optimal speed given the racing conditions it encounters. Inside this clutch, there are a few tiny but critical devices. Among them are a pair of RM22 encoders from Gloucestershire, United Kingdom-based Renishaw. The encoders are both fast and precise enough to monitor speeds up to 30,000 rpm. One monitors the position of the crankshaft in the engine, while the other measures the clutch speed. When these two values are compared, clutch slippage, traction and road conditions can be determined with high precision.
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.
