High-Power Fiber Lasers

New Applications Are Being Enabled by Dramatic Advances in Design and PerformanceHigh-power (multi-kW) fiber lasers are revolutionizing industrial materials processing markets by offering an unmatched combination of performance, reliability, and cost advantages. For example, in sheet metal cutting (the largest application, with more than $1B/year of laser sales), fiber lasers provide the highest cutting speed (especially for thin sheets, the dominant application), scalability to thick sheets (>1”), and the ability to process a wide range of metals with a single tool. Along with low power consumption and high reliability, these capabilities result in the lowest cost per part. Fiber lasers have thus been the fastest-growing segment of the laser market for the past decade.

Finding the Right Chip-on-Tip Camera Technology

You have a great idea that could potentially revolutionize your industry: a new surgical technique, diagnostic solution, or inspection system. You already know getting there will require the latest video imaging technology from an incredibly small, sub-millimeter, package; in other words, a distal chip-on-tip (COT) video camera. The COT needs to integrate into an elegantly designed, flexible device and allow video imaging into anatomy that was previously inaccessible, or image into the tiny dark crevices of our mechanized world. The technology has to be inexpensive, yet video performance needs to be competitive with larger sensor video products with which the market is already familiar. (Figure 1). So, where do you start to identify appropriate video technologies and vendors?

Infrared Cameras Support Advanced 3D Printing Efforts

Additive manufacturing (AM), also known as 3D printing, is quite literally one of the most innovative technologies revolutionizing manufacturing today, in terms of both industry “buzz” and thermal properties. Unlike subtractive manufacturing methods such as machining, the growing range of AM technologies creates components directly from a computer model, adding material only where needed. Wohlers Associates, a leading independent consulting firm focused on these technologies, is forecasting that the value of the worldwide AM market will grow to more than $10.8 billion by 2021, up from just $2.2 billion in 2012. That rapid escalation, however, isn't the result of hobbyists buying desktop 3D printers that cost a few hundred dollars.

CERTIFICATES AND SIGNATURES: How to Ensure Authentication in the IoT

On October 21, 2016, the Internet saw a significant distributed denial of service (DDoS) attack, conducted via a botnet comprising many co-opted Internet-connected devices. The attackers of the network infrastructure were able to control these Internet-of-Things (IoT) devices for a number of reasons, including a lack of strong authentication. Loaded software turned the machines into puppets that interfered with Internet traffic for millions of users.

Researchers Turn iPhone Camera into Optical Sensor

By integrating an optical Micro-Electro-Mechanical Systems, or MEMS, chip into an iPhone camera, researchers at the VTT Technical Research Centre of Finland have developed a new, cost-effective kind of hyperspectral technology. The spectral device will provide mobile device users and consumers with new ways to monitor their environments, including quick food analysis, health checks, and other Internet-connected sensing. Research team leader Anna Rissanen works actively with companies to enable commercialization and new business development based on the team's various sensors.
