CES 2020: The Power Behind the Robot
Reno Rossetti, Principal Writer, Maxim Integrated

At this year’s CES 2020 in Las Vegas, service robots where a big hit on the show floor. It’s easy to understand why: they look and are, indeed, exotic. Among the automated machines I saw at CES: Samsung’s Ballie, a personal assistant the size of a tennis ball that rolls on the floor, following its owner an

The APEC That Could've Been
Jason Lomberg, North American Editor, PSD

The worst collateral damage of COVID-19 is the decimation of global commerce, and trade shows have been hit especially hard – tough to practice “social distancing” with a few thousand people (or more) clustered together. And one of the most unfortunate victims of this new, quarantined reality was the 2020 Ap
