Amid intensifying global energy demands, 88% of the survey participants are struggling to scale…

NORD DRIVESYSTEMS continuously looks for opportunities to gain manufacturing efficiencies and implement practices that have less impact on the environment. In 2012, Fertigungstechnik NORD, a member of the NORD DRIVESYSTEMS Group located in Gadebusch, Germany, developed a concept for heat recovery from machine tools in their production areas. To this day, the recovered energy has…

Anyone who’s visited Niagara Falls in the summer has surely watched the famed Maid of the Mist boats ply the waters of the Niagara Gorge. These sightseeing tour vessels, which appear tiny from above, seem to get perilously close to the thundering water from both the American and Canadian falls, crashing down roughly 180 feet.…

POSITAL’s Wiegand assemblies offer a compact and efficient way of harvesting power for electronic circuits in electromechanical devices, eliminating the need for backup batteries. The operating principle of POSITAL’s Wiegand modules is simple. A “Wiegand wire” is a short length of specially prepared Vicalloy (vanadium-iron-cobalt) wire. When exposed to a changing external magnetic field (e.g. […]

While servomotors remain the gold standard for precision motion control in industrial machinery, the improved performance of stepper motors is making these lower-cost devices an increasingly attractive alternative for many applications. The key to these performance gains is the addition of rotation-measuring encoders, especially the new absolute multi-turn kit encoders from POSITAL. Stepper motors are […]

Many people are familiar with the “wayback machine,” an incredibly useful internet archive at web.archive.org. But until now, there’s been no similar type of system for cyber security professionals. An attack may happen today and then not manifest itself for months or years … by then, it’s nearly impossible to do the sleuthing necessary to figure…

ITT Inc. and its Enidine brand is redefining the shock absorber industry with Sentinel 1, ITT Enidine’s first-generation on-board monitoring system. “Sentinel 1’s new patent-pending design is the first of its kind in the shock absorber industry,” said Farrokh Batliwala, Senior Vice President and President, Connect and Control Technologies, ITT Inc. “By incorporating microelectronic solutions…

Piezeolectric materials are used in many consumer products such as mobile phones, watches, and instruments. Now, scientists at Virginia Tech have found a way to 3D print piezoelectric materials so they are not restricted by shape or size. Xiaoyu ‘Rayne’ Zheng, assistant professor of mechanical engineering in the College of Engineering, and a member of the…
