Medical Wearables: A Product Designer Perspective, Part II

On februari 26, 2016 in Power, Sensors by Mike Parks

The story of medical wearables is no different than the story of technology in general. Exponential growth in capability commensurate with the shrinking of size and cost of products is simply converging to a point that the costs of fielding preventative measures like wearables is a solid alternative to just waiting until something inside of us breaks and we are rushed to the emergency room. While medical wearables do offer great promise in helping us become more proactive in our healthcare, they are primarily data collection devices that may perform some rather simple data analysis. They will have to tie into a larger medical ecosystem that has yet to fully materialize.

Power Management the Hux Way

On februari 24, 2016 in All, Power by Caroline Storm Westenhover

Since processors are following Moore’s Law and batteries are not, people have to look at the other side of the equation, the load, to increase battery runtime. It can be the user’s choice, like ultra low power modes available on new smartphones. Or it can be an old process that is optimized, like migrating from Bluetooth to BLE. Optimizing old processes is possible because of power management options made available by powerful and efficient processors.

Medical Wearables: A Product Designer Perspective Part I

On januari 29, 2016 in All by Mike Parks

Determining the overall health of the human body is a complicated matter that must account for dozens of indicators, including vital signs (blood pressure, heart rate, and oxygen levels), fitness behavior (distance walked and amount of time sedentary), and more complex analysis of internal organs and systems to include blood cell counts, blood glucose, etc. Fortunately there is a lot of work occurring to shrink and converge medical-related sensors into inexpensive tools.

Portable Power: Especially Useful on Pluto

On november 5, 2015 in Power by Arden Henderson

Imagine this. You have just parked your private space ship on Pluto, intrigued by all the recent NASA photos of the not-a-planet small wannabe-could-be-planet, and you realize your cell phone is on its last legs. Power-wise, that is. Not because you skipped the last two upgrades. What to do? For sure, here on Pluto, a zillion miles away from the sun, rigging up some sort of solar screen recharger thing is out of the question. Not that you can't do that and not because it wouldn't work (eventually) but because you need power fast. There are Pluto selfies to take and tweets to be tweeted.

Smart Cooking with RF Energy

On maj 20, 2015 in All, Power, RF by Rudy Ramos

With the exception of changes to the exterior design, to match the flavor of the decade’s décor and the addition of digital readouts, the microwave oven has pretty much remained the same since its inception. That is, until now, with the advent of new high-power LDMOS RF transistor technology, that outdated kitchen appliance we’ve all come to depend on for heating up our lunches might just be getting a new lease on life.

SiC of GaN? Wide-Band Gap RAP Session APEC Day 1

On mars 20, 2015 in Power by Aimee Kalnoskas

Your intrepid reporter, a veritable APEC ingénue, felt compelled to take part in the long-held tradition at APEC: Three concurrent RAP sessions closed out on Day 1. The RAP sessions are composed of a moderator, some apparently famous power panelists, topics that foster lively (geek-bait) debates, and historically large audiences blessed with a beer on their way in. The sessions drew large crowds. (Or was it the free beer?)

APEC Day 2: Hot Rod Layouts, SiC Proponents, and New Options for LED Lighting Drivers

On mars 19, 2015 in Power by Aimee Kalnoskas

If you weren’t certain by Day 1 of the Applied Power Electronics Conference (APEC) exhibition what the running themes were, you found confirmation on Day 2. High density, low power, SiC and GaN all played out through new products, technical sessions, and papers.

APEC 2015: Powering FPGAs and DSPs

On mars 18, 2015 in Power by Aimee Kalnoskas

The Charlotte, North Carolina Convention Center, home to APEC 2015, is a decent size. But with nearly 4500 attendees (a 10% increase over last year), hundreds of technical and industry sessions, and nearly 250 exhibitors, it certainly packed a lot into one space.

APEC 2014 – Download the Presentations Today

On maj 30, 2014 in Power by Landa Culbertson

Nearly 4000 power professionals and knowledge-seekers converged at the Fort Worth Convention Center in March for the twenty-ninth annual IEEE Applied Power Electronics Conference and Exposition (APEC 2014). There was something for everyone it seemed, from hot topics such as high-density power supplies, wide bandgap semiconductors for power electronics applications, wireless charging for electric vehicles, advances in nanotechnology, energy harvesting and 3D packaging to standard subjects such as dc-dc converters, power factor correction, controls, and passive components.
