Apple patent app suggests use of inductive charging for iPhone/iTablet dock

Apple in a newly-published patent application shows a couple of possible docks that would allow an iPhone (a tablet is mentioned too) to be docked in either horizontal or vertical orientation – “or in some treatments, any orientation,” hrmpf.com reports.

hrmpf.com reports that Apple’s patent application “suggests that a charging and data transfer method that uses induction. Inductive charging doesn’t need physical contact just for the devices to be in close proximity. This is an attractive idea because non of the connections need to be physical and can be hidden within the housing. I have not seen reports on how the iPhone is charged but inductive charging would be a great boon- imagine tossing your phone onto a horizontal mat next to your bed and having it happily charging and syncing (and slowly frying your brain!). Bring it on!”

If you own an electric toothbrush, there’s a good chance that it uses inductive charging. However, such transfers of energy from one point to another through ordinary electromagnetic radiation is typically very inefficient. The waves tend to spread in all directions, so most of the energy is lost to the environment. This is why induction charging takes longer and is used for low power devices like toothbrushes and not iPods. Then last November, Marin Soljacic, an assistant professor in MIT’s Department of Physics and Research Laboratory of Electronics, made a breakthrough. Read more about it here.

  1. toothbrushes use the (ineffecient) inductive charging so that all the electrical elements can be sealed off–which is a good thing in a bathroom environment with all the water around!

    So it’s less that toothbrushes are low power (which they are) than that the elements need to be sealed.

    Inductive coupling does not have any reduction in bandwidth, i.e. speed but rather with energy levels. You can pass data extrememly fast with inductive coupling.

  3. B-sabre said: And nobody has really said anything about data transfer through induction. Trying to sink 4-8 Gb of music would probably take a looooooooong time…
    That is certainly true. Which is why God invented BlueTooth and 802.11n! Data transfer over the same frequency as power conversion? Sure, but at the same time? That’s at least a bit of a stretch.
