Apple wins patent for solar-powered portable device

We recently covered how Apple was awarded 563 patents in 2010, but a patent approval announced today is for something we first mentioned back in January of 2010 -- a patent for power management circuitry for solar-powered portable devices. Patently Apple is reporting that the US Patent and Trademark Office published the newly approved patent, which pertains to charging and operating portable devices with solar power via a voltage converter. While most solar chargers designed for portable devices only act as a way to charge the internal battery, this patent is for a way for said power to operate the device as well. By using the converter/booster, energy gleaned from the solar panels could be monitored and configured to both charge and operate a portable device even when not in full direct sun. Could this be a precursor to an iPhone covered in solar cells?

There sure has been a lot of patent talk around here lately, especially when it comes to multi-touch patents, but that just shows that Apple is really stretching its legs and going after innovation instead of resting on its laurels. Can't wait to see what new developments 2011 brings us.

Doesn't this look a little like the Puma phone? It has the back fully covered with solar cells.

At first I was a bit "so?" however this will not be charging just the battery.
"this patent is for a way for said power to operate the device as well."
So that does sound like something new, well done Apple.

I guess these guys won't be in business for much longer:

The patent states the following: "In one aspect of the invention, apparatus for operating a portable electronic device with solar power includes, but is not limited to, a voltage converter and a controller coupled to the voltage converter. "

I haven't actually tried to read the patent, but from the summary it sounds very much like it's for some sophisticated circuitry to maintain constant power in the face of fluctuating light levels. So, a pretty innovative bit of work, and not a patent on running a device from solar cells.

I remember writing to Apple when the Ipad first came out to ask
how about including solar cells in that wide Bezel. I did not think
at the time they would actually do it. Suppose I should have put the Patent
in, but I don't have the odd 40 Billion spare dollars in the bank ;-)

Dude get a clue and stop hating on Apple! Recent article showed Apple applied for something like 450 patents last year vs. IBM's some 5000 patents!! And Microsoft every year applies for more patents than Apple. The difference is Apple makes news!! And editors know most can give a &@&)( about IBM or Microsoft. Plus Apple in the past has gotten burnt by not patent IP. This is the nature of the business. LET IT ROLL!!

@dreamwriter, No. One thing has nothing to do with the other.
@Justin, you didn't use it in context with a notebook or iPad in third grade. Sheesh.
@Camelsnot. Good name for you. What a stupid perspective. Companies spend money to do research and have the right to protect what they design. Other than the big guys like Nokia or Motorola, you don't hear Apple suing everyone. And they won't. Only paranoid a twirp, or should I say snot in this case, waste our time with your greedy scenarios. This is an Apple site snot. Go back to your windows world where you belong.

I'm glad to see Apple working on this green project. I've had a solar calculator for over 20 years now and so it's time that it advances to "assist" the power options on computers like the Mac or other portables. The patent is about a power conversion system and solar is just one big component. Excellent to hear.

@CALTech: Perhaps you didn't in third grade, but very could of... Portable solar chargers have been around a long, long time...
I.E. An example from 2008: http://www.treehugger.com/files/2008/10/7-portable-solar-laptop-chargers-worth-considering.php

Does this mean Apple can now sue the manufacturers of all those old solar calculators from back in the day?

I was just about to comment to that exact same effect. I'm pretty sure I used this technology on a regular basis in the third grade.
