MOTION CONTROL: B&R Industrial Automation has expanded its drive technology product spectrum and is now featuring frequency inverters. All demands of machine manufacturing are met with performance levels of 0.18 to 500 kW. This is an addition to B&R’s successful ACOPOS line of servo controllers, enabling them to supply a complete line of drive technology.The three series with the name ACOPOSinverter S44, X64 and P88 are equipped with serial, X2X and POWERLINK interface and fully integrated in Automation Studio. An additional advantage is easy maintenance because all parameters are saved in the CPU. This allows easier and more efficient commissioning of devices in the series production. The flagship product, the ACOPOSinverter P84, prevents the transformation of braking energy into heat via an optional regenerating unit or by connecting the dc bus voltage, making it more energy and cost efficient. “Our customers have often asked about frequency inverters, so it made sense to add this product to our portfolio,” says Hans Wimmer, managing director of B&R in Eggelsberg.
The 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
