The Power Over Wireless Blog

Magnetic induction could soon spell the end of tangled cables and a frustrating hunt for the gadget’s charger.

Two firms at CES showed off ways to use the phenomenon to re-charge batteries inside gadgets when they are laid on a special mat.

Sensing systems allow devices with very different voltages to be charged at the same time.

The technology can also be used to power household objects such as flat screen TVs or kitchen appliances.

Israeli company Powermat uses RFID tags to identify what is being laid down to charge. The RFID tags are held in a case made to fit around popular gadgets such as iPods, laptops, and mobile phones.

Source: Fulton Innovation (Fulton), the creator and exclusive licensor of eCoupled intelligent wireless power, today announced that it will unveil its latest partnerships — including Texas Instruments, Energizer, and Bosch Power Tools — and eCoupled-enabled products at the 2009 International Consumer Electronics Show (CES) at the Las Vegas Convention Center January 8 to 11, 2009.

Fulton’s booth, located in Central Hall Booth 7916, will feature over a dozen new applications and products that will demonstrate wireless power in the home, office, garage, and beyond. From kitchen appliances to personal devices, Fulton will demonstrate how eCoupled’s intelligent wireless power is a smart, safe, and innovative way to make life easier by powering devices in low, medium, and high power ranges.

“We are happy to return to CES and unveil a selection of new eCoupled-enabled products that will transform everyday life for consumers,” said Dave Baarman, Director of Advanced Technologies for Fulton Innovation. “By integrating our wireless power technology into partners’ products, we continue to prove that there are no boundaries for the application of eCoupled technology.”

At CES, Fulton, in conjunction with key partners and suppliers, will unveil a broad range of new prototypes, products coming to market in 2009, and technology resources that are bringing eCoupled technology and truly wireless power out of the world of “what if” into usable products for consumers. In addition to other key partnerships and devices, Fulton will unveil the following:

eCoupled wireless power, developed by Alticor subsidiary Fulton Innovation, allows for power and data transfer without cables. The technology has been used in eSpring water filters for some years and will soon be appearing in other consumer electronics.

Energizer HardCase Professional Lights and Fulton eCoupled(TM) technology to enable contactless power delivery and charging solutions.

Energizer Battery, Inc. announced it is working with Fulton Innovation, LLC (Fulton) to accelerate development of efficient, intelligent wireless power solutions that can charge portable devices without traditional power cords.

As part of the relationship, Energizer is utilizing eCoupled wireless charging, one of a number of enabling technologies that Energizer views as having great potential in addressing consumers’ needs for portability and power — when and wherever they need it.

Energizer has revealed it’s hard at work on “efficient, intelligent wireless power solutions” that can charge portable devices without traditional power cords.

Working with Fulton Innovation and using eCoupled wireless charging, Energizer says it wants to address consumers’ needs for portability and power - when and wherever they need it.

The Fulton/eCoupled/Energizer project is a “rechargable lighting solution” for in-vehicle use - so presumably a torch, but Energizer has more up its sleeve when it comes to wireless charging.

The battery company has announced it will showcase some of the tech at January’s CES show, with inductive technology featuring in a “charging console that powers devices without the restraints of traditional power connectivity”.

Microsemi Corp., a manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, announced production of its LX5537 power amplifier (PA) for IEEE 802.16e WiMAX and WiBro 4G wireless applications using the 2.3GHz to 2.9GHz frequency range.

Microsemi said the LX5537 delivers 23 percent power-conversion efficiency and extends the company’s RF wireless LAN portfolio into a variety of next-generation wireless network applications.

“With engagements at the leading 4G OEMs, our new LX5537 WiMax power amplifier solves the common problems encountered in mobile and customer premises equipment (CPE) WiMAX designs including challenging performance requirements, solution cost and PCB area,” said Kang Hee Kim, RF product line manager at Microsemi’s Analog Mixed Signal Group. “Leveraging our system perspective, our WiFi and WiMAX PAs offer superior performance without compromising board size and bill of materials costs. The LX5537 joins our successful line of 802.11a/b/g and 802.11n power amplifiers in Microsemi’s RF portfolio.”

David Graham, CEO and co-founder of PowerBeam, is interviewed about the concept of wireless power and the current state of PowerBeam.

Convergence of wireless power technologies inspires global alliance promoting universal solution and electronic convenience worldwide.

A new global initiative to drive convenience in electronics charging was launched at the first Wireless Power Consortium conference at Hong Kong Science Park today.

The Consortium’s eight members include Convenient Power Limited, Fulton Innovation LLC, Logitech SA, National Semiconductor Corporation, Royal Philips Electronics N.V., Sanyo Electric Co. Ltd., Shenzhen Sang Fei Consumer Communications Co. Ltd. and Texas Instruments Incorporated.

A LARGE, GROWING PROBLEM

Wire-free and wireless technologies for transfer of electric power exist today, for example in electric toothbrushes. However, the current charging technology prevents different brands of power sources from charging the same portable device or different portable devices from being charged by a common power source.

Texas Instruments (TI) says that it is working with Fulton Innovation to accelerate development of efficient wireless power solutions that can charge portable devices without traditional power cords. TI semiconductor technologies can help minimize cost, board space, and accelerate time to market of Fulton’s eCoupled technology-based power delivery and charging systems in low-, medium- and high-power applications ranging from cell phones to notebook computers to power tools and other rechargeable applications.

As part of the relationship, TI integrated circuits (ICs) could be designed to support eCoupled inductive wireless power technology, a patented technique that optimizes power transfer under multiple, varying load conditions and spatial configurations. These IC-based solutions would be used to create a universal power source that can charge multiple devices at the same time, including devices that require different charging voltages. Imagine charging a laptop, cell phone, digital camera and MP3 player all at once, in one place, and never plugging a charger into the wall.
