Method and device for manufacturing hot dogs using high power ultrasound: United States Patent: 6,146,674
Parametric Difference Waves for Low Frequency Acoustic Propagation: Unclassified/commercial mind control technology.
Sound velocity sensor AQSV-1500: AQUAMATIC, Denmark
Thermoacoustic Refrigerator: Peter Hoekje, Assistant Professor, Department of Physics, UNI
Thin Film Ultrasonic Transducer for Accurate Control of Fastener Clamp Load: NASA (USA)
Ultrasonic Blaster: sonic shockwaves
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.
Ultrasonic Translator SK-207 (Transtronic): Electronic kit. Hear car brakes, gas leaks or even bats.
Ultrasonic/Contact Stethoscope: The 2047U/C combines the features of a standard electronic stethoscope - with those of an ultrasonic (sounds higher in frequency than the ear can hear) detector.
