Eight Tips for Improving 3D Print Quality

Many companies use 3D printing, a form of additive manufacturing, for prototyping or turning out production parts. It is a computer-based process that lays down layer after layer of a product until it is complete. The process uses metal or plastics and starts with a 3D digital model of the final object. Here are eight tips that will help users improve print quality, along with a few extras for increasing 3D printing speed. 1. Adjust the bed and set the…

Making Robots Smarter | Electronic Design

Download this article in PDF format. The use of robots in factory automation continues to expand because they clearly improve efficiency, cut costs, and improve quality. Fixed-arm robots do most of the work with machine-vision video cameras watching everything. However, the use of autonomous robots called logistical robots or automating guided vehicles (AVGs) is on the rise. Autonomous robots are mobile vehicles that navigate their space safely and perform assigned duties without human intervention. Creating such competent independent machines is…

Automotive Industry Producing Life-Saving Technology On-the-Fly

This article appeared in Machine Design and has been published here with permission. Ford Motor Company took a prudent step to boost containment efforts for the coronavirus by temporarily suspending production at its manufacturing sites in North America. The automotive company reported that Ford is not planning to restart its plants in the U.S., Canada and Mexico on Mon., March 30 as originally hoped. “We are assessing various options and working with union leaders—including the United Auto Workers and Unifor—on…

Near-Infrared Sensor Technology Shines in Low/No-Light Conditions

In the second generation of its near-infrared (NIR) technology for image sensors that operate in low to no ambient light conditions, OmniVision Technologies offers silicon semiconductor architectures and processes that have hit new heights in quantum efficiency. The Nyxel 2 technology provides a 25% improvement over the preceding generation in the invisible 940-nm NIR light spectrum and a 17% bump at the barely visible 850-nm NIR wavelength. These sensitivity improvements enable image sensors to see even better and farther under…

DSP Architecture Targets 5G Endpoints and Radio Access Networks

This article appeared in Microwaves & RF and has been published here with permission. CEVA’s new Gen4 CEVA-XC DSP architecture unifies the principles of scalar and vector processing in a powerful architecture, enabling two-times 8-way VLIW and up to 14,000 bits of data-level parallelism. It incorporates an advanced, deep pipeline architecture enabling operating speeds of 1.8 GHz at a 7-nm process node using a unique physical design architecture for a fully synthesizable design flow, and an innovative multithreading design. This…

Four Challenges Facing AI Leaders

Artificial intelligence (AI) solutions are set to upend a wide variety of industries. By mimicking the predictive, classification, data intensive problem-solving capabilities of the human mind, these technologies are poised to dramatically increase the degree of automation across fields including medicine, transportation and manufacturing, where machines can achieve similar tasks more rapidly. Already, we’re seeing early versions of self-driving cars, automated customer service chatbots, robo-investors and even automated tutoring and writing services. Basically, AI is positioned to soon take over…

Virtual Reality Check: Replacing Industry Conferences with VR

Augmented reality platform makers have not only made real-world cameras commonplace through headsets that offer practical applications such as remote assistance, but have also demonstrated how to benefit from the power of immersive computing across industries. From design and engineering to medicine and education, Microsoft’s untethered mixed reality HoloLens 2 is a case in point. The head-mounted, self-contained computer unit with Wi-Fi connectivity projects 3D images from its projectors onto the glasses, while see-through lenses allow the user to see…

Solid-State EV Battery Exhibits 500-Mile Range

The widespread introduction of affordable, energy-efficient electrified vehicles (including electric and hybrid cars) is essential for meeting ambitious government CO2 emissions targets. And, ultimately, it will create a pathway to a transportation system not based on carbon fuels. The maximum driving range of an electric vehicle is determined by the amount of energy that’s contained in the individual lithium-ion battery cells of the car’s battery pack. These cells are connected in series and parallel arrangements to provide the high currents and high voltage needed to power the electric engine.  While the energy density of the Li-ion battery cell has more than…

Speeding up Linux disk encryption

Data encryption at rest is a must-have for any modern Internet company. Many companies, however, don’t encrypt their disks, because they fear the potential performance penalty caused by encryption overhead. Encrypting data at rest is vital for Cloudflare with more than 200 data centres across the world. In this post, we will investigate the performance of disk encryption on Linux and explain how we made it at least two times faster for ourselves and our customers! Encrypting data at rest…

Augmented Reality Eyes Enterprise Adoption

2020 is set to be the year in which enterprise resource planning (ERP) drives fresh advancements in technology and changes the way whole organizations interact with data—from engineering to HR and finance departments. Machine learning (ML), artificial intelligence (AI), cloud technology and open APIs (application programming interfaces) are all to be taken advantage of in the coming decade. But beyond bringing these emerging technologies to a single platform, ERP developments will not be limited to technology. Following are five trends…
