The challenge
How many devices do you own
that are powered by batteries?
How many chargers, cords,
wires or fresh batteries do you
need to keep all those battery
operated devices powered?
The solution
What if you could easily
recharge all these device at
once, wirelessly, from
anywhere in your home?
Even charge things that move
around your home, like a
phone in your pocket.
Recharging every device one
at a time with individual
chargers doesn’t scale,
especially when the Internet of
Things explodes with more
battery-powered devices.
One power charger that
recharges as many devices as
you have!
Everything just works, because
they’re always charged and
ready to go.
Safe. Efficient. Easy. Scalable. Totally wireless power.
Cota redefines wireless power by delivering remote, targeted energy to
devices safely and intelligently. Built on our patented smart antenna
technology, Cota keeps devices automatically charged so that your world is
always on and always connected.

A home full of power: A single charger powers any Cota-enabled device within a 30-foot radius.
Safe/efficient: Naturally safe technology inherently avoids living objects; a one to many design is highly efficient.
Smart/learning: Smart charger remembers the use pattern of devices and tracks devices as they leave and return to the
home/office; ensuring that every device is always charged and available.
All devices around the house being charged
Driving a design paradigm shift: Not just replacing the batteries we already have; true wireless remote power enables
the Internet of Things and other new devices previously unavailable due to power constraint issues.
Example: iPhone receiver
Cota-enabled remote wireless power means
that one FCC- compliant charger safely
powers many compatible devices in an
average home simultaneously.

Each receiver device sends
out low power signals at a
rate of 100 times per second.
The receiver detects each
signal and “records” the
shape characteristics of the
signal as it is received.
In turn, the charger sends
signals that mimic (play back)
the incoming signal
characteristics with opposite
phase, creating a power
signal that is focused only on
the receiver.

Cota is inherently safe, since it is designed to be
efficient in its power delivery. Additionally, the
technology improves efficiency by avoiding absorption
of its signal by objects in the environment.
Cota-enabled devices send out
weak brief signals to “light up” the
open paths between it and the
charger.
Cota chargers send out signals that
travel only through the open paths
discovered between the charger and
the device needing power. This cycle
happens 100 times a second to
maintain the power location at the
device; safely avoiding any people,
pets or interfering with wireless
equipment.

The charger
establishes the signal
shape from each
device and replays
the signal to power
the devices from
memory.
The charger will also
refresh the signal
shape for each device
multiple times a
second to be able to
follow moving
devices.
