Ultrasonic Power Sensory System
Includes a first and a second transducer coupled together through a coupling medium communicating
undulating pressure wave for the transfer of electrical power into an undulating pressure wave
communicated into an electrical response. This is a signal that can be converted into useful power
for an embedded sensory and actuation control unit. The primary advantage is the transfer of power
through a coupling medium without the use of electrical power wires.

The Audio Spotlight (MIT Media Laboratory)
The Audio Spotlight (TM) uses subtle nonlinear properties of the air to create an extremely narrow
sound beam. This beam ofsound behaves just like a beam of light - 'shining' it at a specific
listener allows only that person to hear it, and projecting it against a surface creates an
acoustic 'image' at the point of reflection. It is the first device that provides total control
over both the location and distribution of high quality sound, something impossible to achieve
with traditional loudspeakers.
