Photo: George Frey/AFP/Getty Images We’ve all been told that 5G wireless is going to deliver amazing capabilities and services. But it won’t come cheap. When all is said and done, 5G will cost almost US $1 trillion to deploy over the next half decade. That enormous expense will be borne mostly by network operators, companies […]

Read this ebook, featuring animated examples, to learn about the control algorithms to drive a brushless DC (BLDC) motor.
Neural control might one day help patients operate robotic prosthetics by thought. Now researchers find that with the help of physical therapy, patients could accomplish more with such neural control than scientists previously knew was possible. Around the world, research teams are developing lower-body exoskeletons to help people walk. These devices are essentially walking robots […]
Illustration: James Provost Once priced out of the reach of enthusiasts, field-programmable gate arrays have become affordable in recent years, and have started popping up in all kinds of neat projects. By the very nature of their reconfigurable hardware, FPGAs can be used in many different ways, such as implementing novel CPUs. But from a […]

Illustration: Chad Hagen In 2007, U.S. vice president Dick Cheney ordered his doctors to disable all wireless signals to and from his Internet-connected pacemaker. Cheney later said that the decision was motivated by his desire to prevent terrorists from being able to hack his pacemaker and use it to lethally shock his heart. Cheney’s command […]
For the last 25 years, researchers have sought to teach computers to measure, understand, and react to human emotion. Technologies developed in this wave of emotion AI—alternately called affective computing or artificial emotional intelligence—have been applied in a variety of ways: capturing consumer reactions to advertisements; measuring student engagement in class; and detecting customer moods […]
