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…

Unique Camera Films Brain in Real Time

Scientists are urgently looking at the different environmental conditions in which COVID-19 can persist. Specific tests include looking at how humidity, temperature and ultraviolet light affect the disease, how long it lives on different surfaces, as well as the way the COVID-19 compares to SARS and MERS, or the common cold viruses currently in circulation. The World Health Organization (WHO) and other health officials use this information to make sure their guidance is appropriate. COVID-19 is transmitted through droplets of…

The Clinical Lab Test for the COVID-19 Virus

Rodney Rohde is the head of the Clinical Laboratory Sciences department at Texas State University here in San Marcos.  His department is where people go to learn how to run the horrendously complicated tests that clinical labs do, such as the CDC 2019-novel coronavirus (2019-nCoV) real-time RT-PCR diagnostic panel.  That’s the official name for the CDC’s test for the coronavirus.  I wouldn’t know even that unless Rodney had directed me to the CDC website, where you can download the entire…

New nanosheets for near infrared imaging — ScienceDaily

Egyptian blue is one of the oldest humanmade colour pigments. It adorns, for instance, the crown of the world famous bust of Nefertiti. But the pigment can do even more. An international research team led by Dr Sebastian Kruss from the Institute of Physical Chemistry at the University of Göttingen has produced a new nanomaterial based on the Egyptian blue pigment, which is ideally suited for applications in imaging using near infrared spectroscopy and microscopy. The results have been published…
