  • Use of external driver to energize a seismic source
    Patent number: 10890680
    Abstract: Disclosed are seismic sources that may utilize an external driver to energize the air in the seismic source for generation of acoustic energy. An apparatus for generating acoustic energy may comprise a seismic source comprising an internal cavity configured to contain a fluid. The apparatus may further comprise a piston external to the seismic source and in fluid communication with the internal cavity, wherein the piston operable to energize the fluid in the internal cavity of the seismic source. The apparatus may further comprise a linear motor coupled to the piston.
    Type: Grant

  • Use of external driver to energize a seismic source
    Patent number: 10488542
    Abstract: Disclosed are seismic sources that may utilize an external driver to energize the air in the seismic source for generation of acoustic energy. An apparatus may comprise a seismic source comprising an internal cavity configured to contain a volume of a fluid. The apparatus may further comprise an external driver, wherein the external driver and the seismic source are coupled to permit fluid communication between the external driver and the internal cavity of the seismic source, wherein the external driver is configured to create a pressure wave that drives the seismic source and a gas resonance. The apparatus may further comprise a fluid reservoir, wherein the fluid reservoir and the external driver are coupled to permit fluid communication between the fluid reservoir and the external driver.

  • Underwater sound projector system and method of producing same
    Patent number: 8139443
    Abstract: An underwater sound projector system comprises multiple sound projectors, each sound projector being capable of producing acoustic pressures. The sound projectors are held in close proximity such that the sound projectors interact with one another via the acoustic pressures produced. In embodiments, the number and/or spacing of the sound projectors are adjusted based on target performance parameters.
