Apple to patent a new wireless battery charging method
Apple is a company with a very active imagination. The Cupertino-based giant has registered a patent describing a wireless charging method for its products. Users will be able to synch their gadgets both with iTunes and iCloud via Wi-Fi thanks to iOS 5. Taking into account this new feature, a Wi-Fi battery charging method does not seem a farfetched idea anymore.
How does this method work? According to Apple’s patent, iMacs or Macbooks will capture a NFMR (near-field magnetic resolution) energy source and then use it to charge iPads, iPhones or iPods wirelessly. Compatible wireless keyboard and mice could also be charged in this manner but they require coupling antennas, therefore charging peripherals is a bit more complicated. The gadgets to be charged need to be placed at a maximum distance of one meter in front of the iMac or Macbook.
The good news is that Apple’s wireless charging method can be used on older iMac versions as well. An USB device needs to be connected to the iMac so as to capture energy and transfer it to other iOS gadgets and peripherals. The bad news is that the charging field is active within an area of one meter; therefore users have to put their gizmos near the iMac which limits the functionality of wireless battery charging. Another issue is the level of radiation involved by such an energy field, especially now when WHO admitted that mobile phone radiation can cause cancer.
This might be one of the patents Apple will never put in practice, but it is good to know the company is preoccupied by such ideas.
