• - 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 t
  
• - Meters energy and frequency in ultrasonic and megasonic cleaning tanks used in the semiconductor, wafer, disk drive, flat-panel display, electronics and parts precision cleaning industries.
  
• - 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
