Herd Mentality, Showing a New Way Forward Caroline Storm Westenhover
Back in May 2015, Tesla released the Tesla Power Wall a 7kWh home battery. The idea being that it can be connected to the DC bus in a home and charge from renewables, mainly solar panels and wind turbines, when the production is high but the use is low. Later, they can be discharged during the evening peak times when load demand exceeds supply.

Truly “Wireless” Wireless Charging Emerges Barry Manz
Wireless charging has been less than a spectacular success. Competing (that is, incompatible) standards, a slow reception by smartphone manufacturers, and RF-inhibiting aluminum phone housings and protective cases have resulted in a slow adoption rate by consumers. However, while the prime players have been battling each other, two companies have come up with solutions that eliminate the need for the inductive coils, magnetic resonance, charging pads, and mats that are required by other techniques. Intrigued?

Powered On: The Advancements in Portable Power Justin Risedorf
I dread the beep my phone makes when it’s at the end of its charge. Not because I’m uncomfortable without my phone being on at all times, but because, of course, it always seems to die right when I need it most. I’m using my phone’s navigation to drive through some unfamiliar part of town when it’s dark and rainy and I’m almost out of gas and – beep – my phone is about to die.

Medical Wearables: A Product Designer Perspective, Part II 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 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.

Which Switch: Who Cares if it’s AC or DC?! Rudy Ramos
Have you ever tried to use a switch in an application and wondered whether the difference between the AC and DC rating on switches really matters? ­­There is a fallacy that any switch can be used so long as its current rating exceeds the maximum load requirements in the circuit. Who cares if it’s AC or DC, it’s only a 12VDC system right? Wrong; when it comes to switches, the differences in current-carrying capacity are dramatically different between AC and DC circuits and this is typically reflected in the switch’s AC and DC ratings.

Power Storage Caroline Storm Westenhover
There have been some really interesting innovations in electrochemical storage devices (e.g. batteries and supercapacitors) in my area of focus. These days, bigger products demanding more energy are moving towards battery power.

Wireless Charging: What You Need To Know Barry Manz
Charging the batteries of smartphones, tablets, and other battery-operated products is a bit of pain especially if you’re “heavy user”. And how many times do you succeed the first time in correctly plugging in that micro-USB connector on our Android phone? So you would think wireless (inductive) charging would have taken off like a rocket, but it hasn’t for the usual reason: a battle between incompatible standards, with the typical consumer confusion as a result. If you haven’t delved into this area, here’s where wireless charging currently stands.

Unlocking the Power of High-Voltage Innovation Ramanan Natarajan
Why does high-voltage innovation matter? It’s a question we hear frequently, and the answer may surprise you. Recently, my colleague Chris Schairbaum and I co-authored a white paper about how we are redefining power management through high-voltage innovation. Here, we have answered some of the more common questions we receive from customers about high-voltage.

Portable Power: Especially Useful on Pluto 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.
