Training a Neural Network to Fall


Who knew falling was so complicated? “I don’t want to work on a fall detection system ever again,” said MbientLab CEO Laura Kassovic in front of an ARMTech Con audience. The audience laughed as she flashed a picture of what could now be a better approach—the Apple Watch Series 4, which had recently been announced. “The Apple 4 has the fall detection sensor built in. It’s probably... » read more

Dirty Data: Is the Sensor Malfunctioning?


Sensors provide an amazing connection to the physical world, but extracting usable data isn't so simple. In fact, many first-time IoT designers are unprepared for how messy a sensor’s data can be. Every day the IoT motion-sensor company MbientLab struggles to tactfully teach its customers that the mountain of data they are seeing is not because the sensors are faulty. Instead, the system d... » read more

Testing Millimeter Wave for 5G


By Susan Rambo and Ed Sperling The telecommunications world is hurtling toward 5G, but there is no consistency about how this next-gen wireless technology will be rolled out across various regions and plenty of unknowns about how it will be tested and how reliable it will be initially. A fair amount of confusion exists around what 5G constitutes in the first place. There is sub-6GHz 5G, w... » read more

Schottky diodes: One 2D material equation to rule them all Specifying the right materials for the heterostructure of 2D Schottky diodes—which consist of a metal touching a semiconductor—means designers have to wade through sometimes conflicting theoretical models to select materials. “It is not uncommon to see a model, whose underlying physics fundamentally contradicts with the physical ... » read more

Better AI technique for chemistry predictions CalTech researchers have found a new technique that uses machine learning more effectively to predict how complex chemicals will react to reagents. The tool is a new twist on similar machine learning techniques to find more effective catalysts without having the time-consuming trial-and-error research, making it a time-saver for drug researchers. ... » read more

People Vs. Self-Driving Cars


If you’re a screenwriter—or a car salesman—you’re already thinking of ways to write non-sci-fi self-driving cars into a movie script. Automobiles have been integral to the plots of gritty noir crime movies, heist flicks, romantic comedies, and obviously, road movies. What's clear is the self-driving car won’t be the ideal getaway vehicle anymore, particularly if there is no steerin... » read more

Carbon Nanotube DRAM


An IP design house has developed a scalable DRAM replacement using carbon nanotubes (CNTs) that abolishes the DRAM refresh rate, stores the content permanently, has better timing than DRAM and is scalable. And it lasts for somewhere between 300 and 12,000 years. “Carbon nanotube memory—it sounds so sexy that I could just shut up and not say anything,” said Bill Gervasi, principal syste... » read more
