Parametric Difference Waves for Low Frequency Acoustic Propagation - Unclassified/commercial mind control technology.
Sound velocity sensor AQSV-1500 - AQUAMATIC, Denmark
Method and device for manufacturing hot dogs using high power ultrasound - United States Patent: 6,146,674
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.
