Wireless charging... What in the world happened to that?!

[sircody]

History
In 1894 Nikola Tesla used resonant inductive coupling, also known as "electro-dynamic induction" to wirelessly light up phosphorescent and incandescent lamps at the 35 South Fifth Avenue laboratory, and later at the 46 E. Houston Street laboratory in New York City.[5][6][7] In 1897 he patented a device[8] called the high-voltage, resonance transformer or "Tesla coil." Transferring electrical energy from the primary coil to the secondary coil by resonant induction, a Tesla coil is capable of producing very high voltages at high frequency. The improved design allowed for the safe production and utilization of high-potential electrical currents, "without serious liability of the destruction of the apparatus itself and danger to persons approaching or handling it."

So you are apparently in Glasgow and you think the US is destroying the planet? I gather you are not aware that US environmental laws are still among the strongest in the First World. You might want to compare the Clean Water Act, Clean Air Act, National Environmental Policy Act, Comprehensive Environmental Response, Compensation and Liability Act, Emergency Planning and Community Right-to-Know Act, Occupational Safety and Health Act, Consumer Product Safety Act, Endangered Species Act, etc. etc., to what exists in other countries and then perhaps notice how long all of these laws have existed. Unfortunately, that would require you to think before spewing BS....

i dont care about all these Acts etc u speak of... its well known that the US is a wasteful resource hog .
no offence

and why do you say "aparently live in Glasgow"?? i actualy live in Paisley which is biggest town in Scotland in its own right. Glasgow is just my nearest city so people get a rough idea of where i am. Glasgow airport is in paisley.
i dont understand the "aparently" though lol

I don't know I loved it on my palm pre. Once you start using it going back to plugging in a charging cable is like taking a step back in technology.

It's certainly not a must have but it is nice.

Ageed, had it on Palm Pre, using plug is so old school, once you experience inductive charging you will always want it.

My idea of a "smart" induction charger would be a combo of NFC and induction charger. The charger pad would sit idle, drawing absolute minimum power until an NFC/Induction capable phone was put on it. The phone would send a message to the pad via NFC to turn on the charger, which it then starts to charge the phone. Every 60 seconds or so, the pad would poll the NFC connection to make sure the phone is still there, if it is, keep charging. If the phone isn't found, go to back to sleep.

The phone would also have the ability to send a message via NFC to say that its fully charged and put the pad into a trickle charge mode (but still poll for no phone every so often).

In addition, the charging pad could be programmed just like any other NFC tag so you can make one pad be the "bed side" pad and another be the "office desk" pad. This would allow you to make your phone react to each pad in a unique way, like turning on the screen to a minimum brightness with a clock on it for the bed side.

I guess you are unaware that Ontario industries are a major source of acid rain in the northeastern US and (for that matter) eastern Canada. Having your house in order means more than turning off a light and being proud of it. It also means political action to address macro level environmental abuse that is as Canadian as anywhere else on the planet.

I don't think I pointed any fingers at anybody, in any of my posts......feel free to point it out, if I did. (and I'm still not pointing fingers, just pointing out some facts)

Acid Rain - Progress Report on Acid Rain - Learn More - Our Changing Planet - UMAC
What is being done in North America?

Acid precipitation is a problem that crosses international borders. Acid precipitation has caused significant environmental damage in Canada, with most of the problem originating from industry in the United States. The United States emits almost 5 times as much sulfur dioxide and 20 times as much nitrogen oxide per year than does Canada. This U.S. pollution is carried into eastern Canada by upper-level winds. Lakes, forests, buildings, and monuments have all been damaged. In the early 1980s, the problem was so severe that in eastern Canada almost 96% of the forests suffered damage. In Ontario, significant declines in growth rates of forests within the past 30 years were linked to acid precipitation from industrialization and urbanization.

If you don't know...UMAC is Upper Midwest Aerospace Consortium. As a consortium, UMAC is led by the University of North Dakota, and includes participants from academia, industry, and government located throughout North Dakota, South Dakota, Montana, Wyoming, and Idaho. UMAC is connected with NASA and collaborates with the EROS Data Center and other partners.


Being "proud of it" wasn't my point. Leaving a one amp charger on 24/7 is a fairly small source of wasteful energy. I do my part,in my world, and that was my point. I live over a thousand miles from Ontario, and I don't follow what is going on in their province.

was searching for a big 3 device Pixel Qi charger and stumbled on this:
High Quality Powerqi Phone Wireless Charger Qi For Samsung Galaxy S3 I9300,Galaxy S3 Wireless Charger - Buy Wireless Charger,Phone Wireless Charger Qi,Galaxy S3 Wireless Charger Product on Alibaba.com
Galaxy S3 Wireless Charger Qi - Buy Galaxy S3,Qi Wireless Charger,Wireless Charging Set Product on Alibaba.com
I'd say that's just a bittttt of a variation on price..LOL

 

[kryptonite_2448]

Looks as though the producer of these has perfected the pins and it can close perfectly now.

This plus Palm TouchStone = $30.00 wireless charging.

I personally don't want that much electricity radiating in my space. Besides you would end up overcharging much easier.

This amuses me on multiple levels. Thanks for the LOL.

SamSung's Wireless Group have their Standard Set, It's Not Qi !!!!

Alliance for Wireless Power approves its specification, edges closer to truly cable-free charging
posted Oct 30th 2012 1:13AM

Design by committee might not be the death knell for technology after all. Over four months after the Alliance for Wireless Power was founded in earnest, the coalition has already greenlit a specification for its partners to work from. The guideline lets device makers start building devices that charge through a magnetic resonance technology more forgiving of distance and material than Qi while simplifying the process through short-range wireless formats like Bluetooth 4.0. While the A4WP group hasn't made all the details public, it's holding meetings this week to speed up the commercialization process -- it's here that we'll learn whether the corporate bureaucracy is just as quick at getting wireless charging hardware into our hands as it is handshaking on standards.


Alliance for Wireless Power Rolls Out Flexible Wireless Power Specification

- Will support simultaneous charging of multiple devices with different power requirements

FREMONT, Calif., Oct. 29, 2012 /PRNewswire/ -- Alliance for Wireless Power (A4WP), a global and independently operated consortium focused on bringing wireless power to the consumer electronics marketplace, today announced that the technical working committee has approved a more flexible wireless power specification that will allow consumers to charge their mobile devices on a variety of compatible surfaces.

"The Alliance for Wireless Power and its members have been focused on creating a more flexible wireless power specification that sets the stage for formal standardization in the future," said Dr. Kamil A. Grajski, president of the A4WP. "Approval of the A4WP wireless power specification establishes a true path forward for the commercialization of wireless charging that will satisfy the needs of most consumers. A4WP and its members will now set their sights on building compliant wireless applications that can be integrated by key industries including automotive, furniture and retail."

The A4WP specification is based on a concept of spatial freedom, which extends wireless power applications beyond the accessory or add-on market to fully integrated solutions in the device as well as surfaces such as furniture and automobiles. The A4WP specification brings a number of unique benefits to the wireless charging ecosystem.

* For consumers, the A4WP specification supports simultaneous charging of multiple devices with various power requirements such as handsets, Bluetooth headsets, MP3 players, GPS devices and mobile tablets
* For industrial designers, the A4WP specification leverages a loosely coupled magnetic resonance technology and provides more flexibility for charging applications to be installed into automobiles, furniture and other surfaces
* For the consumer electronics industry, the A4WP specification takes advantage of broadly adopted wireless technologies, such as Bluetooth 4.0, which will allow manufacturers to minimize hardware requirements

"We know from our own global research that wireless power is an attractive feature for consumers. But to see it proliferate into our mobile devices, into our cars or at our favorite coffee shop, the industry must see that it can be practically integrated into many different devices and charging surfaces," said Steve Pazol, vice president of business development at Qualcomm. "The A4WP specification gives integrators and manufacturers that clear path forward to integrate wireless charging into almost any type of mobile device or surface."

"Today's consumer is often running around with multiple mobile devices, and it's clear that wireless charging technology will become critical to powering these devices as they advance further," said KiHo Kim, Executive Vice President of Samsung Electronics. "We endorse the A4WP specification because it is designed from the ground up to support this multi-device lifestyle and gives consumers the best available wireless charging experience."

A4WP members will meet October 30 and 31 in Dallas to discuss strategies to bring wireless charging technology to mobile consumers and the mass consumer electronics marketplace. The two-day program will include briefings on technical specifications, certification procedures and global regulatory considerations.

Anybody try this set up? Will this work if my phone has a otterbox defender case? Not my pic but I'm thinking of buying this.

 

[stevepierce]

Why pay $50.00?? While it's cheaper to do it yourself, good alternative found in the forums of webosnation.com

I bought three of these backs from this ebay seller and none of them worked. In one email he said the S3 has to be horizontal as the magnets won't hold on the touchstone puck. Putting a shim under teh touchstone is a stupid idea but even then they still don't work.

That's how Samsung's Wireless power Group A4WP and Duracell Powermat, which was part of the Group, is going to work. Use Bluetooth and NFC to communicate and that will also make the hardware requirements needed for charging a Minimum requirement. The coils have to have a circuit board of some type right now to tell the charger pad that it is on pad and tell it what watt or amp etc to send to that phone. From there it will grow to being able to charge without having to put phone on charger, it will trickle power while phone is in the area where the charger is which means while phone is used it will not deplete the battery etc.

If you've ever owned a Blackberry with charging pins and the dock you'll know. My bold 9700/9780/9900. All of them had it and auto bedside mode once I placed it on the charger, oh how I miss that. You don't have to look for the the usb cord or be afraid of you're plugging it in incorrectly at night, just place it on the pod and it turns the screen into a clock and dims the screen significantly. That is definitely a few of the things RIM did very well with their line up of phones.

I haven't seen the Blackberry's charger before, were the pins you speak of, 2 metal contacts on the outside part of the case? That's Conductive charging pretty much same as corded charging , direct contact, just much easier then plugging it in. That was very cool for Blackberry to do that.....Thumbs up for them!!!!

i wish Web Os had hit it off in the UK but the truth is, ive never touched or knowingly saw a Palm device lol. i was probably into Symbian at the time.
ive read a lot of love for the OS though so im sure someones gona buy it and make it their own?

global s3, UK. Ask me anything and ill reply even if its just an intelligent (or stupid) guess

Yeah man, Web OS was and still is the best OS ever designed for smartphones. It still is the only one that had Multitasking.
You could be working in a app or on call and you could hit the single button and it would shrink in size, like windows does a window on desktop, and open another app etc, and when you needed to go back to other app, hit the button and it would shrink and they were like cards lining up or like what your apps screen looks like displaying all your apps.

touch the app you want to go back to and it returns to full screen, and the apps etc never closes until you shrink it and toss it off the screen and then it shut down..

You could Text, email, talk and go to a chat room all at the same time without having to use the back button to get to app or hold the home button....this way we have to on android is sooooooo old feeling compared to My old Palm Pre i had when it was new and Multitask all on 3G while iPhone couldn't do half of what Pre did...LOL

HP has made the Web OS open source and I think LG is working with it...

They have something like this that's very similar. Not quite all the NFC capabilities that you want (which would be awesome BTW) but there is communication (via RFID). Check out these induction charging systems, specifically the Powermat - Is Inductive Charging the Way to Go? | Apartment Therapy

NFC is a format Standard of RFID being two-way communication while RFID is pretty much one way, Powermat's has two-way, phone tells pad i'm here so feed me...lol...while pad tells phone ok, go and when charge is full, phone tells charger to stop etc....LOL But NFC is very cool now and will be even more in near future. NFC works with WiFi, Bluetooth etc...
