In Pursuit of Power

CATEGORIES : Power Solutions/AUTHOR : Ron Wilson

It is no news that power design for modern systems is hard. The escalating demands of advanced chips—huge bursts of current, multidecade operating ranges, fast transients, and digital mode controls—have turned supplying power at the point-of-load (PoL) from an exercise in arithmetic into an adventure in high-bandwidth mixed-signal design. Looking in the opposite direction, pressure […]

Helping Out Reality

One day was a summer day like any other summer day. The next, everything had changed. Like swarms, like zombies they came, walking randomly in public places, staring lost into their smart phones, growing increasingly agitated. And then, just as suddenly, they were gone. Pokemon Go had swept across our town, another little dot on […]

Blockchains Unchained

CATEGORIES : Embedded system, IoT/AUTHOR : Ron Wilson

It first came to our attention as the plausible-sounding but obscure data structure that made Bitcoin unhackable. Then some people lost a lot of money in attacks on Bitcoin exchanges. But before the cyberspace version of yellow crime-scene tape could come down, blockchain was back. Exonerated for the bitcoin fiascos, blockchains were now being researched […]

Is that Drone the Sound of Progress?

Let’s set aside traditional senses: a low-frequency, continuous sound; a male bee; an unsounded string on a musical instrument. We are interested in aircraft. Somehow in the mid-20th century the military began calling unmanned target aircraft […]

Hubs Become Central to the IoT

CATEGORIES : IoT/AUTHOR : Ron Wilson

Even before real systems are widely deployed, the Internet of Things (IoT) is rushing into a period of rapid evolution. Early—and, frankly, simplistic—ideas about IoT architecture are giving way to more nuanced views, often based on analysis of data flows and on hard questions of why the IoT really matters. The result will be new […]
