We've all been there, forgetting to plug the cell phone, MP3 player, or other
portable electronics into the recharger at night, leaving it a useless lump
the next day. Part of the problem is the system itself, depending on a direct,
wired link to the power infrastructure. But what if you could put your gadgets
down, and they could absorb energy from the ether?
Based on 10 years of research, Fulton Innovation's award-winning and heavily patented
eCoupled technology may be the answer.
Using inductive coupling, the technology
transfers energy from one device to another
through a shared electromagnetic field. The
eCoupled power-supply circuit and primary
can be packaged within a pad, cord, wand,
box, or bowl. The system also may be embedded in desktops, tray tables, or consoles.
Previous attempts at wireless power have failed because of the amount of power
lost between the primary and secondary coils. But the eCoupled technology uses
resonance-seeking circuitry (in which the reactive impedances cancel) that dynamically
optimizes the power transfer under multiple, varying load conditions and spatial
configurations, thereby optimizing the coupling coefficient. In fact, it provides
milliwatts to kilowatts of power at up to 98.6% efficiency.
While seeking resonance, the primary circuit
adapts its operation to match the characteristics of the given load. To maintain operation
at resonance, the power-supply circuit automatically adjusts the frequency of the current
applied to the primary coil.
In traditional methods, the position of the primary coil relative to the secondary
may cripple the performance of the load. But by continually seeking resonance,
the eCoupled technology's secondary may be moved or rotated about any axis relative
to the primary, so efficient transmission of electrical power will still be
provided.
The eCoupled technology only delivers power when needed thanks to its intelligent
feedback, profiling, and control system. It also includes data-transfer capabilities.
Based on amplitude modulation (AM) technology designed into the primary and
secondary coils, data may be transferred in excess of 3.3 Mbits/s.
