Digital Braille speaker communicates using mid-air pulses

Researchers at Bayreuth University have developed a digital-age speaker system that permits the blind to read Braille using ultrasound waves in mid-air. Instead of either fixed or refreshable physical dots, the HaptiRead system relies on precisely focused tiny puffs of air generated by acoustic force. “With HaptiRead, we investigate for the first time, in a user study with blind people, the possibility of using midair haptic technology for the purpose of presenting Braille text as a touchless haptic sensation,” said…

Micron Lifts Sales Forecast as Demand in Data Centers Soars

Network interface cards (NICs) have been on the market since shortly after the first PCs in the mid-1980s. However, over the past few years, we’ve seen the emergence of SmartNICs. Each company in this market has a different definition of the SmartNIC product segment. The most basic definition is as simple as a NIC that’s programmable. Conversely, others have overloaded the concept by heaping vast amounts of silicon and firmware into their implementations. At the end of the day, though,…

Protein coating extends shelf life of perishable fruits and vegetables — ScienceDaily

Eggs that would otherwise be wasted can be used as the base of an inexpensive coating to protect fruits and vegetables, according to Rice University researchers. The Brown School of Engineering lab of materials scientist Pulickel Ajayan and colleagues have developed a micron-thick coating that solves problems both for the produce and its consumers, as well as for the environment. When the coating was applied to produce by spraying or dipping, it showed a remarkable ability to resist rotting for…

Powering the Army of the Future

Professor Bill Ma in the Department of Mechanical and Aerospace Engineering is proposing new electric power technology to support Army operations in 2035. Solar energy is expected to meet the energy demand for a variety of equipment associated with Army multi-domain operations in the future. Prof. Ma presented his white paper during a public forum on May 18 to the National Academy of Sciences, Engineering, and Medicine. Ma, who co-authored with Pengtao Wang, presented his white paper during a public…

HP Releases New Additive Manufacturing Material, Services and Alliances

Many Americans can relate to the weight challenge that faced Branch Technology in a project at Field Museum in Chicago. Instead of shedding a few extra pounds after the holidays, the 3D printing company worked with engineers from Chicago Flyhouse to face a task that involved safely supporting approximately 28 tons in a facility that attracts more than 1.65 million visitors annually. Branch Technology’s solution involved the use of its patented additive manufacturing process to create unique architectural products. Chicago…

How to Program Hardware with MicroPython: A Beginner’s Guide

>> Electronic Design Resources..>> Library: Article Series.. .. >> Series: MicroPython for Embedded Systems MicroPython is a compact implementation of the Python 3 programming language designed to work with microcontrollers. Initially announced back in 2013 as part of a Kickstarter project created by Damien George, MicroPython eventually became one of the preferred firmware options for microcontroller programmers and enthusiasts alike. Damien ended up created his own line of hardware that comes equipped with MicroPython right off the bat. However, the…

There’s an App for That: Bosch Rexroth Reveals Web-Based Automation Platform

FDT Group, an independent not-for-profit industry association that supports the evolution of FDT technology, released its platform-independent FDT 3.0 – FDT IIoT Server (FITS) standard, built to empower digital transformational benefits for the automation supplier and end-user communities in the process, hybrid and discrete markets. The association also released FDT 3.0 Developer Toolkits to help the vendor community begin development efforts with a modern Integrated Development Environment (IDE) to easily create and customize next-generation, cross-platform FDT 3.0 solutions. The new…

New way to detect blood clots — ScienceDaily

Researchers in the Department of Biomedical Engineering at Texas A&M University are working on an entirely new way to detect blood clots, especially in pediatric patients. Unlike what a biology textbook may show, blood vessels are not straight cylinders. They are tortuous, meaning they have complex curves, spirals and bends. When the blood reaches these curves, it makes changes to its fluid mechanics and interactions with the vessel wall. In a healthy person, these changes are in harmony with the…

Research finds obese kids under lockdown in Italy ate more junk food, watched more TV at expense of physical activity — ScienceDaily

Lockdowns implemented across the world due to the COVID-19 pandemic have negatively impacted diet, sleep and physical activity among children with obesity, according to University at Buffalo research. The study, published in April in Obesity, examined 41 overweight children under confinement throughout March and April in Verona, Italy. Compared to behaviors recorded a year prior, the children ate an additional meal per day; slept an extra half hour per day; added nearly five hours per day in front of phone,…

National Electrical Code Updates Bring Higher Efficiency

During the first few weeks of the coronavirus pandemic, when software engineers and other white-collar professionals were singing the praises of Zoom and thriving in a work-from-home environment, many mechanical engineers found themselves suddenly unable to easily access their designs. Software engineers and much of the business world (sales, marketing, accounting, human resources, etc.) have long used cloud-based productivity tools, but most hardware designers were still using installed on-site software for product development. The government shutdown of non-essential businesses around…
