Marriott Woos with Wireless Power

WPC members are making their way into hotels and Hoteliers attract tech-savvy millennials with Qi.  As Elise Ackerman writes in Forbes  “… launched this month, portable cubes that allow for both (Qi) wireless and wired charging were distributed to 29 properties. Guests can pick up a cube, made by (WPC member) Kube Systems, from the desk in the lobby and charge their devices while they work, drink or socialize. Dail (Michael Dail, Marriott Global Brand Marketing Lead) said the pilot is a response to requests from customers with a seemingly insatiable appetite for electric charge”. 

The members of the WPC and the Qi standard are opening new worlds of services, products and markets.

The World’s First Resonant Charger that is Qi v1.1 Compliant

On the heels of the WPC’s addition of two new transmitter topologies to the Qi standard in Beijing last month, ConvenientPower revealed the first products that utilize one of these designs.  A new Qi v1.1 transmitter topology, called the A27, enables ConvenientPower’s Tx R2 transmitter series that charge existing Qi phones at a distance of up to 20mm. When these transmitters are combined with a ConvenientPower receiver, the charging distance is increased to 30mm. 

This technology launch represents an important wireless charging breakthrough as consumers, automobile and furniture makers, hoteliers and restaurateurs have been looking for this flexibility.  Not only does increased charging distance enable new products, services and increased manufacturing flexibility, this innovation demonstrates the power of WPC’s co-opetition style of standards development.  When leading technology competitors agree to cooperate and collaborate with a common vision, good things happen for consumers and businesses alike.

  • ConvenientPower’s Tx-R2 platform embodies the following new features
    • Uses the latest Qi A-27 coil structure
    • Qi 1.1 compliant at 5mm
    • Enables charging existing Qi phones up to 20mm *
    • Enables  charging up to 30mm with ConvenientPower’s new receiver design
    • Adapts to charge continuously (dynamically) across its Z-distance range.
    • Charges a receiver that is up to 35 degrees off parallel
  • The Tx-R2 is a platform that combines superior user experience and design freedom for developers and manufacturers. The Tx-R2 platform is Qi-certifiable and demonstrates what is possible beyond the present Qi 1.1 ecosystem.

The Wireless Power Consortium is organized to inspire the best minds in the industry to work together and create a standard that brings real value.  The test of this approach is the resulting number and variety of products and services.  With more than 600 products and 34 types of transmitters, there is no doubt that the WPC is showing the way to a world without wires.

*Performance depends on Qi receiver.

Hospitality Industry Sees the Value of Qi Wireless Charging

It’s happened to everyone. You reach the restaurant, bus stop, hotel or aiport gate just as your phone battery is on its last leg. Panic sets in. We call that feeling battery anxiety.

The WPC is working to eliminate that battery anxiety, and earlier this week, Marriott installed Qi-compatible charging stations by Kube Systems in its newly redesigned great room lobbies in 29 U.S. hotel locations, making our goal one step closer to becoming a reality.

This rollout is important for wireless charging because it signals the adoption by the hospitality industry, a move that will help drive other hoteliers and restaurateurs to follow in their footsteps. Marriott recognized the value that wireless charging brings its guests and jumped on the opportunity to differentiate its brand with innovative technology.  Marriott technologists worked with Kube Systems to fine-tune the design and they chose Qi because it is the leading and most widely adopted standard.

Wireless charging in hotel environments not only opens the door to unique services only Qi can enable, but also a personalized in-room experience, simplified check-in and marketing for hotel customers. This is a big milestone and a sign of more to come.

With the rollout of Qi in hotels, soon your entire travel experience could be supported by wireless charging, from the bed-side charger, to the car, to the airport, and now to the hotel. With the implementation of wireless charging spots at every touch point in your life and travel, the fear of battery anxiety will be a forgotten worry, since your battery will always be full.

Major Milestones for V1.2 Resonant Specification

WPC’s v1.1 specification, supported by the largest ecosystem comprising over 200 member companies, enables the most efficient and cost-effective wireless power solutions based on inductive power, close-coupled technology. 

WPC’s Resonant Task Force (RTF) will deliver an extension for WPC v1.1 specification for a best-in-class magnetic resonance technology to address applications that require multi-device charging, increased spatial freedom, increased charging at distance (Z-height), and devices that are designed for different power levels. 

The RTF has set high goals for backward compatibility to existing v1.1 specification, efficiency, transmitted power, FOD, thermal design, and other critical parameters. Meeting these goals would result in the most advanced and compelling products addressing a broad set of applications such as smartphones, tablets, PCs, wearables, automotive, and infrastructure.

Members saw significant achievements and progress at WPC’s Leeuwarden meeting in June, last month.  After hundreds of combined engineering hours by 5 of the world’s leading companies, here’s what happens with an open standards organization when the best minds in the industry collaborate:

  • Q1.1 receivers based on inductive v1.1 specification and charging at a Z-height of 7 mm, are now capable being charged at a Z-height of 30 mm
  • New magnetic resonance v1.2 receivers can now be charged at Z-height of 45mm, expecting further Z-Height in final production designs
  • Backward compatibility between Qi v1.1 and Qi 1.2 systems (v1.1 receivers charging on v1.2 transmitters, v1.2 receivers charging on v1.1 transmitters), allowing consumers protection of investment
  • Multi-device V1.2 Receivers charging on a v1.2 transmitter with one inverter, delivering lowest cost designs

Reliability of Alzheimer's Patients GPS tracker

Posted on Tuesday 8 April 2014, by Menno Treffers

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.
