MPI 1 Providing challenging ultrasonic solutions Basic Elements of MMM Systems How MMM Systems Operate Ultrasonic systems based on our unique MMM (Multi-frequency, Multimode, Modulated) technology may be used as structural actuators capable of delivering high power sonic and ultrasonic energy to a large or small loads. MMM uses proprietary techniques to initiate ringing and relaxing multimode (wideband high and low frequency) mechanical oscillations in a mechanical body to produce pulse-repetitive, frequency, phase and amplitude modulated bulk-wave-excitation on that body. MMM (Modulated, Multimode, Multifrequency) ultrasonic generators utilize a new and proprietary technology capable of stimulating wideband sonic and ultrasonic energy, ranging in frequency from infrasonic up to the MHz domain, that propagates through arbitrary shaped solid structures. Such industrial structures may include heavy and thick walled metal containers, pressurized reservoirs, very thick metal walled autoclaves, extruder heads, extruder chambers, mold tools, casting tools, large mixing probes, various solid mechanical structures, contained liquids, and ultrasonic cleaning systems. Every elastic mechanical system, body, or resonator that can oscillate has many vibrating modes as well as frequency harmonics and sub harmonics in the low and ultrasonic frequency domains. Many of these vibrating modes can be acoustically and/or mechanically coupled while others would stay relatively independent.
