E-paper: the power to revolutionise vehicle production lines

E-paper: the power to revolutionise vehicle production lines Pairing an e-paper display with location sensors and low-power wireless technology enables the creation of in-vehicle displays for use on production lines By HD Lee, CTO, Pervasive Displays (http://www.pervasivedisplays.com/) Production lines revolutionised manufacturing, enabling factories to turn out high volumes of identical products quickly and economically. But as consumers’ desire for customisation has grown, so has the complexity around production lines. Those working in or overseeing manufacturing facilities now need to cater for numerous subtle differences between items as they come through. And while much of the work is automated, humans still play an important role, including in car manufacturing. For quality assurance purposes, it’s crucial that production line workers have easily accessible instructions available for each vehicle as it passes through their  ..

Adding a low power display to a Maker project

Adding a low power display to a Maker project By Hardy Kuo, Field Applications Engineer, Pervasive Displays Have you ever thought how great it would be if you had a sign on your front door that said ‘Hello’ just as you approached to put your key in? Or you could see if you should take an umbrella to work with you, just by looking at your coffee table? Or you knew if you were running low on sugar just by glancing at the closed cupboard door? If the answer to any of these questions is ‘Yes’ then you’re probably already a Maker. If it’s ‘Yes please!’ then you’re a Maker in the making and you might just be looking for e-paper displays. Accessing technology for your project The number of single-board computer modules available to Makers is on the increase. Platforms like the Raspberry Pi (https://www.raspberrypi.org/) family give everyone access to technology that, not so long ago, would only have been available to lar ..

Why e-paper displays will run for 22 years in coin cell powered IoT applications

Wednesday, November 02, 2016
Why e-paper displays will run for 22 years in coin cell powered IoT applications? By Scott Soong, CEO, Pervasive Displays You’ve carefully selected your sensor, found the lowest power MCU for your battery-powered IoT application, optimized your code to minimize energy consumption and chosen the lowest power wireless solution to send packets of data where they need to go. Now you want to figure out how to add a display to your application without completely trashing the power budget. That’s the challenge faced by many IoT product designers, for example those designing remote meters or smart tags. If they think only in terms of dot matrix displays, it’s a challenge they’ll struggle to overcome. Let’s assume that you want your display to operate for five years with CR2032 coin cell batteries as the power source. These have a typical stated capacity of 220 mAh, from which we might reasonably assume a nominal real-world operating capacity of 88% ..
