Samsung patent filing reveals a wireless charging pad that could work from distance

A patent application filed by Samsung to the USPTO reveals a dual wireless charger that can charge more than one device at a time using two different methods of magnetic charging. According to Sammy's patent, its dual wireless charger uses both magnetic resonance and magnetic induction charging in the same product. Samsung's current multi-device charging pad employs only magnetic induction. The pad will determine the device that is being placed on it, and automatically use the appropriate magnetic charging method to refresh its batteries.

Magnetic resonance charging is considered the more advanced method between the two. Magnetic induction requires the transmitter (the charging pad) to be placed no more than 7mm away from the receiver (the smartphone). With Magnetic resonance, the charging pad and the handset do not have to be in close proximity to each other,

We could see Samsung introduce its new wireless charging pad in February when the Samsung Galaxy S9 and Galaxy S9+ are expected to become official.

So updating their existing multi wireless charging pad is following Apple's idea?

I have a better one - According to this website, it has a list of all the company's who have joined the Wireless Power Alliance. Apple only recently joined after they patented their own technology for charging a device from a distance. However, its technology, would not work, because it require licensing technology already develop by 2 of the companies that introduced the technology; Intel and Qualcomm The concept was pioneered by Nikola Tesla. A company called WiPower licensed the technology and is working to bring it to market. They have had working demos on their sites for years. They even have the tech needed to provide wireless charging to device with metal casings. In the early 2000's, Qualcomm purchased WiPower. Apple did not come up with the idea. They saw what others were doing and tried to patent a way to do it without licensing WiPower tech and it failed. So they recently joined the alliance to help them with their versions. The proof Apple recently joined is here - Samsung has been an active member since 2014 according to this. This is the information a little research will gain you. This is the stuff PhoneArena does not do and why they are not a real tech blog, but a tech tabloid for Apple.

Hmmmm copying apple you say.......​/art/50308318/ Funny how suddenly apple becomes master of stuff, when they introduce features that has existed for years before....

Oh, He edit it, nice.. I guess the chief editor still neutral overall

As usual, while everyone got concepts and patents, Apple actually sells it to public.

What color is the sky in your world? In the real world, other invent, design and manufacture products, then Apple tries to patent them.

I bought mine in IKEA years ago. And so did the guys who bought the Nokias with the Fatboy wireless charger. But of course those things are just apple ripoffs.....

You do realize you're typing this comment in an article describing wireless charging; a thing that phones were using 3 years before Apple finally got it. Do you type this stuff with a straight face? By the way, I've had Ikea's 3 device charging pad for 2 years.

Hmmm - Where have I heard this before? Oh yeah! Apple! Expecting Samsung's version to be half baked like pretty much everything they do anyway...

Really? Samsung is part of the Alliane for Wireless Power an has acces to the tech, because they are a Qualcomm partner. Apple also joined this alliance a couple tears ago. So sure you heard Apple was working on such, but they didn't start it. They are as always just using someone else hard work and copying it. Apple did patent their own version and it failed. So they joined the alliance to help get their own to work, which also failed.

Samsung may have been the first to it but now that Apple has adopted it, it will become more mainstream and widely adopted. The industry will finally move forward with Apples help.

You mean how Samsung fast wireless solution employs and works with 2 popular wireless standards in one device, while Apple using such 4 years later only supports one standard? Half-baked? You mean like how Samsung provides a fast charger in the box, but apple doesn't? Or like how apple's one-handed mode, removes 60% of the data off the screen, while Samsung one-handed mode still keeps 100% of the screen content? Or how Apple requested the manufacturer of the 3D array to make it less secure, so it goes out the door faster? You mean like the iPhone has no headphone jack, or home button and yet the device is less water-resistant than the Galaxy S5 which has a removable battery, home button, headphone jack and other holes? What is your exact definition of half-baked so I can understand how Samsung has ever released something half-baked? You mean how like Apple new camera options are still all in beta? Or how when Siri was released it was in Beta? Or how when Apple Maps was released, it was in Beta? Isn't beta basically defined as half-baked? You mean how Apple released the iPhone 6, with a frame that wasn't fortified with more material so it wouldn't bend in your pocket? You mean how when an iPhone that is plugged in, when dropped in water, doesn't overload the circuit breaker, so that it stops sending power down the cord, so that you won't get electrocuted to death? I mean I literally can list 50 things that are half-baked in Apples products in general.

The note 7! That's all I need to say in reply to your essay (which tbh I ain't gonna read through)...

The original technology was design and engineered by a company called WiPower. The company was later purchased by Qualcomm. They have plenty of demos on their website showing you can wirelessly charge from a distance. The issue has been how to make it safe to use around people and animals. The demos are here and have been here since Qualcomm acquired the company way back in 2003 I believe it was. "The Alliance For Wireless Power is an industry standard group that uses the principles of magnetic resonance to develop a wireless energy transfer system over distance. The WiPower system uses directed and controlled magnetic fields to replace traditional power cords.[1] To do this, the transmitter utilizes one or more primary windings in order to induce an even magnetic field above its surface. A receiver in the magnetic field uses a secondary winding which captures the magnetic energy and converts it back to electrical energy.[2] WiPower's system was based on modified coreless inductive technology and dynamically adjusts power supplied by the transmitter to power demanded by the receiver without the need for control systems or communication.[3][4] As such, the company's technology represents a simpler design versus alternate wireless power solutions.[5] The system is capable of supplying power to multiple receivers simultaneously that are placed on top of the transmitter in any position or orientation, and the company has reported DC to DC efficiencies between 60-90%.[6] These technologies were combined in a backwards compatible manner with Intel and Qualcomm's wireless power over distance technologies to be standardized by the Alliance For Wireless Power." PhoneArena is the only tech site that doesn't research anything it posts. It just uses an RSS feed to get articles other sites are posting, and simply copies and pastes the info and changes t up a bit, so they don't get cited for copyright violations. Apple has also joint the alliance, because they were trying to add this tech to the iPhone X, but failed so they went with Qi. Samsung still has a one up because they support both of the 2 top wireless standards in one device. Which is why they call theirs "adaptive charging".

The free Samsung wireless charging pad I got from buying my Note8 charges through a thick leather folio case. Samsung's wireless technology is already great, I love that they are trying to better it even further!

Just make sure it doesn't catch fire. Or is that 'feature' to keep you warm during winter?? I'm sure that's one 'feature' Apple won't "copy"

Ya and also you make sure that "You are holding your phone right so that it will never bend or have swollen batteries." This one feature no one can copy.

Samsung had to issue a total recall of the Note 7! Antennagate and swollen batteries are nothing compared to that total and utter embarrassment!
