Power Trip for Mobile
phones, PDAs, digital cameras and a host of other consumer products are seeing
phenomenal growth, fueled by the constant addition of functions that create more
excitement in the marketplace. But for engineers, this increase in features
poses a big challenge: how to do more while also extending battery life.
is one of the hottest aspects of design today. It ’s important in everything
from autos to testing equipment and more. Prolonging battery life is at the
heart of power management today, and that often includes controlling heat,
controlling refresh rates, shutting down functions when they aren’t needed, and
judicious component selection. Indeed, managing power consumption entails
critical thinking about nearly every component in the system, from controllers
to displays to power converters, as well as software.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
