Reliability of Alzheimer's Patients GPS tracker

Qi improves the reliability of Alzheimer's Patient GPS tracker

GPS trackers alert caregivers the instant a patient with special needs wanders outside of their home and allows patients to call for help when they feel lost.

This technology works well provided the patient keeps the GPS tracker fully charged. That is a challenge for all users but particularly difficult for these patients.

The Dutch service provider LiveSafe provides a mobile alarm device which is activated by pressing the alarm button. Within a few seconds contact is made with the alarm centre. If the user is no longer able to press the button himself, the mobile alarm device automatically contacts the alarm centre via the so-called “fall alarm”. The alarm centre agent has access to the user’s records and knows exactly who is calling, where the person is at that moment and what their most important personal and medical details are, so that the right help can be provided.

LiveSafe makes it easier to keep the GPS tracker charged by providing a wireless charging solution. In cooperation with ZENS, the wireless charger serves as place to store the GPS tracker overnight, without need to plug in wires.

200th member: Aircharge by Ergo

Aircharge by Ergo is the 200th Member of the Wireless Power Consortium

We’re excited to announce that Aircharge, a division of Ergo, has recently joined the Wireless Power Consortium. Their new membership marks the 200th member milestone of the WPC.

I had the opportunity to ask Steve Liquorish, CEO at Aircharge-Ergo, a couple of questions about why they decided to join the WPC and support the Qi standard.

Here’s what Steve had to say:

Why did your company choose to join the Wireless Power Consortium?

We are a lead supplier and manufacturer of ergonomic office furniture, products and LED lighting. For the past year, we’ve been looking to integrate wireless charging capabilities into our products in order to take them to the next level and offer the best user experience to our customers. We decided to join the WPC because Qi is taking the lead as the global standard for wireless charging, and we were ready to move forward with our wireless power design roadmap pretty aggressively.

Big players in the industry are embracing Qi, including the committee of automobile manufacturers, CE4A, which includes Audi, BMW, Daimler, Porsche, and Volkswagen. With the products that we develop, we believe that the Qi solution fits nicely with our roadmap. And as Qi continues to be built into an increasing number of mobile devices, we have a big role to play in helping to build out the infrastructure to enable consumers to use this technology wherever they go.

What’s your take on the future of wireless power and where do you see the industry heading?

From our perspective, we see the whole wireless charging ecosystem rolling out over the next few years. We envision consumers having various charging areas around their community where they can charge their phone on-the-go, wherever they are. While this is an emerging process at the moment, it is clear that the convenience of charging your mobile device while at home, in the car, or in your office is important to consumers. As we become increasingly dependent on mobile devices, our innovative products will help make drained batteries a thing of the past. 

We’re excited to see the innovative products Aircharge will bring to the wireless charging community. Welcome, Aircharge!

Hands-on with Qi

Posted on Tuesday 28 January 2014, by Menno Treffers

Users describe their experience with wireless charging.

Hands-on with Qi

Qi delivers a great user experience, not only in theory but in real life. Read what these users experienced:

"I’ve also found myself converted to wireless charging — the Nexus 5 supports the Qi charging standard, and I’ve been using it with a Samsung charging pad for the past couple of months. (In fact, I’ve only plugged my Nexus 5 in to charge a handful of times in total.) Phil's been using the Zens Wireless Charger. It’s a feature we’d love to see on more devices in the coming year." - Alex Dobie in Android Central.

"Now I have it, I wouldn't be without it. I've put charging pads in the two offices I work in regularly, and by my bed. In combination with NFC tags to set a profile in each place, they really improve the usability of a smartphone, so much so that both capabilities will be non-negotiable requirements for my next phone." - Geoff Cambell in a comment on an article in The Register.

"Nokia spoiled me with wireless charging in the Lumia 920 and now I want that in all of my devices. I have three Qi wireless charging pads at home and in the office and find it much more convenient to just set down a device on the pad rather than messing around with a microUSB cable and figuring out which end is up to plug it in." - Matthew Miller on ZDnet, explaining Seven reasons to buy the new Google Nexus 7.

"I’m pleased with the wireless charging accessory, it works like it’s supposed to, and wireless charging definitely is an added convenience after you’ve used it for a while. [...] Of course the nice thing about Qi is that after you have the cover, you can always shop around for a pad that suits you." - Brian Klug on AnandTech

"I considered wireless charging a gimmick until I picked up a wireless charging stand. After using it for a short period, I bought another one, they're pretty damn awesome especially if you pick the phone up and put it down often." - User #159443 at Whirlpool Forums

"I will admit to believing it was a gimmick at first. 6 months later, it is a necessity. I love the wireless features, and would never buy another phone without it." - Mikado_Wu commenting on an article about the JBL Power Up

"If you've got a couple of Qi chargers you really, really do appreciate the convenience. And the Qi standard is now winning critical support, Samsung will support it in the S4, and so it looks like being the VHS rather than the Betamax of the wireless charging wars." -  Andrew Orlowski, The Register

"To be honest plugging a cord into a phone once every day or two isn't exactly a trying task so at a glance wireless charging sounded more of a novelty than a necessary technology but how wrong could I be! The action of just putting your phone down on to the charging plate as you would put your phone on the coffee table/kitchen bench/desk is a no brainer, it's not some sci-fi mumbo jumbo, it is a logical solution to an existing problem." - Wade, TelecomTech blog (

"I’m becoming a huge fan. Getting the micro-USB plug into most phones is a pain particularly when I’m tired and just want to go to bed. The number of times I’ve awakened to a dead phone because I didn’t push the plug in all the way is embarrassingly large as a result. With inductive charging [...] you just set the phone down on the charger and walk away finding the phone fully charged when you wake up. It may seem like a little thing but it was a nightly annoyance to get that damned plug in the right way in a dark room and not having to do that is almost worth this phone alone." - Rob Enderle, TG Daily

"The [HTC Droid] DNA features Qi wireless charging technology. The phone began charging within a couple of seconds after being placed on the Nokia Lumia 920's charging pad." - Sherri L. Smith, Laptop Mag

"Once you have a wireless charger around, then using it becomes second nature, you top-up more often than you would. It’s one tiny hassle removed from the day. The phone doesn’t need to be carefully aligned with the plate, so you just plunk it down and let it charge. Which it does fairly rapidly; there is a speed penalty to wireless charging but it’s surprisingly light: wireless power-ups are around 10 to 20 per cent slower than direct charging, I found." - Andrew Orlowski, The Register

"[Wireless charging] is not a must have, but once you have it, you’ll wonder how you ever lived without it." Michelle Maisto, eWeek

"We're big fans of the wireless charging ability, as it puts an end to fumbling around in the dark for a cable and then taking 20 attempts to finally get it plugged in – popping the Lumia 920 down on its plate is just a more pleasing experience." John McCann, Tech Radar

The [Google] Nexus 4 also fully supports the Qi wireless charging standard, which means you can use any Qi-capable charging pad to refill your battery -- we even took it for a spin on the Fatboy recharging pillow sold by Nokia, and it worked like a charm.” - Brad Molen, Engadget

The convenience of simply dropping the Nokia Lumia 920 on the Fatboy pillow is great. I have it sitting on my desk so when I am there the Lumia 920 is charging up which can lead to it being charged up more often.” Mattew Miller, ZDNet

"We managed to hold the Nokia Lumia 820 a good inch off the charging plate and for it to still be getting a charge through, which shows how efficient the charging plate is.” Mike Brown, NokNok




Is wired charging more efficient?

Posted on Monday 16 December 2013, by Menno Treffers

Is wired charging more efficient?

In a study presented during the Wireless Power Summit, Kalyan Siddabattula compared the efficiency of wired and wireless battery chargers.

The surprising conclusion is that wireless chargers can be as efficient as wired chargers.

The study shows that significant efficiency gains can be made by combining functions in the power conversion chain for wireless battery charging. The strongest effect is to integrate the charger function into the power receiver. This is called "direct charge".

The details are in this pdf file: "Why Not A Wire? The case for wireless power".



Qi at the University of Oregon

Qi at the University of Oregon

CP Furniture Systems, Inc. Brings Qi Wireless Charging to the University of Oregon

Guest blog by Oliver Kapp, National Sales Manager, CP Furniture Systems, Inc.

The University of Oregon and CP Furniture Systems, Inc., a subsidiary of C+P Moebelsysteme GmbH & Co KG of Germany – one of Europe’s leading furniture manufacturers – recently partnered to design a unique and innovative locker system for use by its football team’s athletes and coaches in their brand new facilities. This past August was the grand opening of the locker room.

Oregon wanted a facility that was unique, innovative, and something that hadn’t been done before. They collaborated with CP due to the company’s capabilities to drive the technology concept of their locker room space.  Only CP could offer a complete custom option for the University that included a steel frame, printed corian doors, stainless steel shelving, electrification, wireless charging, among many different options. Upon seeing CP’s manufacturing capabilities, the architect and owner’s representative were very impressed and chose to go forward.  

One of the coolest amenities offered with the lockers are the electronic components. CP partnered with the Wireless Power Consortium to integrate wireless charging into the locker shelves that allow the athletes and coaches to recharge their mobile devices without the need to plug them in. The Qi wireless charging modules, using Leggett & Platt technology who is also a member of the WPC, are embedded and built directly into the shelves allowing for seamless and easy charging of mobile devices. There are more than 60 Qi-enabled devices that offer the best user experience, which is why consumers love using Qi.  The wireless charging is in addition to integrated standard outlets and USB chargers.


This locker room also has everything from padded floors, lounges, and even gaming stations for the athletes to kick back and relax. The lockers themselves feature ventilated structures to eliminate odors, bacteria-resistant surfaces, as well as a central online locking system with customized touch pads, which show Oregon graphics, the player’s picture, name and number.  This locking system can also be serviced remotely. 

The wireless charging capabilities are a unique feature and something that can be customized and incorporated into any locker room system. It is not only unique to lockers.  CP incorporates it into desks, workstations, conferencing, lounge and meeting furniture.  Check out some pictures below.  CP is always on the forefront of integrating new and existing technologies into their furniture.  Their newest creation is the Cegano SmartTable where wireless screen mirroring of many different platforms meets stylish conferencing furniture.  Recently, CP won the Gold Award at Best of Neocon in 2013 for this table in the technology category.


Qualcomm, Verizon join board of management of the WPC

Posted on Friday 20 September 2013, by Menno Treffers

Qualcomm Inc. and Verizon Wireless have joined the board of the Wireless Power Consortium.

Qualcomm, Verizon join board of management of the WPC

The WPC is managed by the 24 companies that are a so-called “regular member” of the WPC. Each regular member has one vote in the board of management.  Each regular member has  same rights and obligations. There are no companies with special voting rights or other perks.

The board of management of the WPC (also called the “steering group”) includes many companies from the mobile phone industry  such as HTC, LG Electronics, Nokia, Panasonic, Qualcomm, Sony, Texas Instruments, Toshiba, and Verizon Wireless.  You can find the complete list of regular members on our website.

The mobile phone industry thrives on open standards that allow competitors equal say in the creation and evolution of key wireless technologies. Take for example 3G, LTE, Bluetooth, and WiFi: all these standards were created by standards development organizations that allow competitors a seat at the table where decisions are made.

The Wireless Power Consortium is committed to the open development of Qi. We encourage competitors to join and we create the conditions in which standards developments is fast and fair. The WPC creates the level playing field that makes it easier for members to invest in R&D and the result is more choice for consumers.

You can see the result:

a) The Qi ecosystem offers the best user experience for mobile phone users

The Qi ecosystem offers unrivaled choice of over 330 devices such as the Google Nexus 7 tablet and smartphones like the Blackberry Z30, Droid MAXX by Motorola, DROID MINI by Motorola, Samsung Galaxy S4, Nokia Lumia 1020, and Google Nexus 4.
