METHOD OF CONTROL OF VIBRATION-SEISMIC SOURCE Russian patent published in 2006 - IPC G01V1/02 B06B1/00 

FIELD: vibration engineering.

SUBSTANCE: method comprises generating loading pulses of different polarity whose duration is less than the half of the vibration-seismic vibration half-period and affecting the emitting plate with the pulses. The duration of the pulses should provide the decrease of vibration velocity of the emitting plate of the vibration-seismic source down to zero when next loading pulse of opposite sign comes for one- or bi-polar modulation of the loading pulse.

EFFECT: enhanced power coefficient.
