Understanding Wireless Power - Part I

BY DAVE BAARMAN AND JOSHUA SCHWANNECKE WITH FULTON INNOVATION

With differing perceptions of wireless power demands among developers and consumers, it’s

important to find common ground for future wireless power solutions.

water treatment system to eliminate

6-log reduction or 8-log reduction

of bacteria and viruses. It ended

up becoming a flagship product for

Amway.

How did you get into electrical

engineering and when did

you start?

I always wanted to be an engineer.

Much of my purpose revolves

around being someone innovative

and who can develop new products.

I am very interested in research and

development—my first job was

actually in automotive research and

development.

I also have a very entrepreneurial

mind. I started my own business,

sold it, and became a consultant.

I later got hired by Amway as a

consultant to provide wireless

power to a water treatment system.

Out of that relationship, the eSpring

water treatment system was born.

We created a wireless-powered

lamp system to be dropped into the

From developing that water

treatment system, we created a very

unique wireless power system that

had a lot of versatility and was highly

resonant in the way that it would

adapt and respond to environmental

changes like temperature, space

and pressure. It was then that we

realized we really had a winning

product.

Dave Baarman - Director of Advanced Technologies

Can you tell us more about

the 400 patents you hold in

wireless power technology?

We began developing the water

treatment system and the wireless

power system about 15 years ago

and we saw a very open white-

space of intellectual property

in the patenting world. So we

started patenting back then on

this technology, and really haven’t

stopped since. Actually, as it sits

right now, we have a portfolio of over

700 patents pending or granted in

just the wireless power space.

because once you become certified,

they are deemed as interoperable,

and you become part of the WPC

and can put the Qi logo on your

products, just like Bluetooth or Wi-

Fi.

found in a traditional power cord.

Wireless power requires two coils:

a power supply coil (usually in a

surface or pad) and a receiving coil

(in a device). A shared or coupled

electromagnetic field is generated

when the power supply and

receiving coils are positioned near

each other, which then wirelessly

transfers power to or charges the

device.

Can you tell us about being

a founding member of the

Wireless Power Consortium?

The goal of the Wireless Power

Consortium is to establish Qi

(pronounced ‘chee’) as the global

standard for power rechargeable

electronic products. It has more

than 100 members including

industry leaders in mobile phones,

consumer electronics, batteries,

semiconductors, components,

wireless power technology, and

infrastructure such as wireless

operators, furniture and automotive

parts companies.

Can you tell us more about

Fulton Innovation and the

technology it is developing?

Fulton Innovation’s goal is to

commercializing new and innovative

technologies that improve the way

we live, work, and play. Fulton

is working with a wide range of

industry-leading companies to

integrate wireless power technology

into infrastructure and electronic

devices enabling consumers to live

a truly wireless life. Fulton Innovation

was established in 2006 to advance

wireless power technology, which

was first developed in 1998 by

parent company Alticor for its

eSpring water purification system.

The technology was further

developed, branded, and officially

launched as eCoupled technology

in 2007. Fulton licenses its eCoupled

technology to manufacturers so they

can incorporate eCoupled into their

products.

eCoupled technology uses this

concept to eliminate the need

for power cords. It creates an

electromagnetic conduit, combined

with an intelligent control system

that constantly monitors the power

flow to ensure optimal efficiency

and safety.

Some member companies include

Motorola, Samsung, Philips, Verizon

Wireless, Texas Instruments, LG

Electronics and many more. A full

list of member companies can be

found here .

How did you and Fulton

Innovation get involved in this

project?

Fulton Innovation originally

developed the concept of eCoupled

wireless power in 1998 to solve a very

real problem—finding a safe way to

power a UV lamp in a water purifier.

It was then that Fulton realized the

true potential of wireless power and

its broad applicability to virtually

any electronic power system. Since

then, Fulton has enhanced and

developed the technology and is

dedicated to commercializing new

and innovative implementations of

wireless power that improve the

way we live, work, and play.

Fulton and the WPC believe

that global standards are a vital

step in driving widespread

consumer adoption of wireless

power, and opens up the door

for full interoperability between

device manufacturers and OEMs

worldwide. Globally recognized

standards give consumers

confidence that their purchases

will work with compatible devices,

regardless of the brand.

Can you tell us about the

eCoupled™ intelligent wireless

power project?

eCoupled technology is intelligent

wireless power based on inductive

coupling that allows for safe and

efficient power transfer without

wires. eCoupled technology is

based on the principle of near-

field resonant magnetic induction.

With magnetic induction, electricity

travels via magnetic fields instead

of through a physical connection

of conductive materials like those

How does Qi certiication

work?

We do Qi precertification for our

partners. The actual certification

is done by laboratories that are set

up to do this type of testing through

the WPC. It works out pretty nicely

How has this technology had

a signiicant impact on the

wireless power industry?

The Qi global low-power standard,

set by the Wireless Power

Consortium (WPC), includes

elements of eCoupled technology.
