- 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.

- Ultrasonic power sensory system - A system includes a first transducer and a second transducer coupled together through a coupling medium communicating undulating pressure wave from the first transducer to the second transducer for the transfer of electrical power from an external controller energizing the first transducer transducing the power signal into an undulating pressure wave communicated through the medium to the second transducer traducing the undulating pressure wave into an electrical response signal that can be converted into useful power for powering an embedded sensory and actuation control unit. The primary advantage of the system is the transfer of power through a coupling medium without the use of electrical power wires. United States Patent: 6,127,942
