Apple and WiTricity team together for wireless charging

by Mark R

I have to thank my wife for sending me the Source for this story. She sent the Source link via IM with a message that read “Have you heard about this wireless extension cord?”

All I could think about was: “How can you have a wireless extension cord?” That’s like an oxymoron. This is the magic of WiTricity, based on wireless charging research from MIT.

The idea is pretty simple: a circuit converts standard AC electricity to a high frequency and feeds it to a WiTricity source, like the flat rectangles that you see on the left in the photo. A WiTricity device tuned into the same frequency as the source can get power through “resonant magnetic coupling”. As you might have imagined, it is good for lighting, television, computer, not to mention video and audio components without plugging anything into the wall. I got a video from the WiTricity Showcase after the jump.

Apple apparently loves this technology, and has put together a patent application so users can power their computer, keyboard, mouse, or other electronic devices.

Personally, I could use this technology now, as I keep forgetting to charge my phone when I am at home. If I could just leave it in the room, and let it charge wirelessly, I would be glad. Yes, this is technology that I and many others would welcome to the market. My only concern is how safe it is. Leave a comment if you know more about it than my Sources.

“Apple apparently loves this technology, and has put together a patent application so users can power their computer, keyboard, mouse, or other electronic devices”

Apple is infringing on dead people’s ideas and patents now? Nicola Tesla anyone?

“Electrical Transformer Or Induction Device”. U.S. Patent No. 433,702, August 5, 1890

“Method Of Utilizing Radiant Energy”, Patent No. 685,958 November 5, 1901

“Apparatus for Transmitting Electrical Energy”, January 18, 1902, U.S. Patent 1,119,732, December 1, 1914 (available at U.S. Patent 1,119,732)

I guess since their best patent lawyer just quit, they decided they better go after dead people from now on. No wonder they maintain such strict controls on their hardware. If anyone ever looked into their designs closely they’d be sued out of business.

This is different than nicla teslas patents, it does not utilize radiant energy or induction. it converts it to magnetism and transfers energy via magnetic field. even if this were the case the company filing the patent for this technology is witricity not apple. all of this information you could have found out if you watched the video or go to witricities website

“Apple apparently loves this technology, and has put together a patent application so users can power their computer, keyboard, mouse, or other electronic devices.”

So, I read that Apple is applying for the patents. Maybe you could read as well?

“a circuit converts standard AC electricity to a high frequency … device tuned into the same frequency as the source can get power through ‘resonant magnetic coupling’.”

As per Tesla’s Electrical Transformer Or Induction Device. U.S. Patent No. 433,702, August 5, 1890

Just Apple showing it’s double standards as usual, and a mac fanatic defending them by saying that I didn’t read or watch a video. Why must everything degrade to ad hominem attacks with Apple fanbois?

Apple did not create Witricity. Witricity is its own company. Apple I’d just interested in their technology. Apple isn’t Infringing on anything. How you got “apple is stealing from Tesla” by reading this shows that you know nothing about anything.

@George Orwin.
you are completely lost on this subject.
try to look into it more before you accuse Apple of patent infringement, which is a hefty charge.
