Power/Performance Bits: Mar. 6


Neural network chip Neural networks are both slow and consume a lot of power. This made researchers at MIT examine the important aspects of the nodes within a neural network and to see how each part of the computation could be improved. The outcome was a dedicated chip that increases the speed of neural-network computations by three to seven times over its predecessors, while reducing power c... » read more

Diamond metrology The U.S. Department of Energy’s Ames Laboratory is building a new instrument called an optical magnetometer. The system will help researchers understand the properties of new magnetic nanomaterials. The system, dubbed the NV-magnetoscope, makes use of the properties of nitrogen-vacancy (NV) centers in diamonds. According to researchers, diamonds have a flaw, or imperfect... » read more

3D printed supercars Divergent Microfactories has rolled out a new approach to auto manufacturing based on 3D printing. The technology is based on what the company calls a Node. A Node is a metal alloy that is produced using 3D printers. The Nodes are combined with carbon fiber tubes, which, in turn, enable the development of a car chassis.

Deadweight machines The National Institute of Standards and Technology (NIST) is in the process of cleaning, restoring and recalibrating its 4.45-million Newton deadweight machine. NIST’s deadweight machine, the largest of its kind in the world, is equivalent to one million pounds-force. Built in 1965, the deadweight system consists of a stack of 20 stainless steel discs about three meter... » read more

Whispering sensors Inspired by a whispering technology from a famous cathedral, Washington University in St. Louis and Tsinghua University in China have developed a new sensor that can detect and count nanoparticles down to 10nm and perhaps below. Researchers have devised a Raman microlaser sensor in a silicon dioxide chip. The microsensor is called a whispering gallery mode resonator (WGMR... » read more
