  • Publication number: 20190391604
    Abstract: A method for changing a set point of a system where period of a dominant resonance of the system is determined, a change profile for the set point change is processed; a time period for the set point change based on the period of the dominant resonance in order to minimize excitation of the dominant resonance is also processed; and the set point change is actioned according to the processed change profile and the time period.

  • Patent number: 9857487
    Abstract: A marine seismic streamer comprising a solid, hydrophobic core member that is encased in a hydrophobic streamer skin/casing. The hydrophobic streamer skin may be extruded onto and/or heat welded to the hydrophobic core member. The hydrophobic streamer skin/casing may comprise a thermoplastic polyurethane that includes fluorine and/or silicon moieties, silicon, polydimethylsiloxane or the like. The hydrophobic streamer skin/casing may reduce the drag of the streamer and may provide anti-biofouling properties to the streamer. A hydrophobic paint, coating or polymer may in some instances be disposed on top of the hydrophobic streamer skin/casing.

  • Publication number: 20170101329
    Abstract: Generating hydrogen peroxide in situ in a water environment to mitigate biofouling of a water sensor. A hydrogen peroxide generator submerged in the water environment generates hydrogen peroxide to remove/mitigate biofouling of the water sensor. The water sensor may be an electrochemical sensor and the hydrogen peroxide generator may be an electrochemical system that is integrated with the sensor. The water sensor may be able to operate without interference from the generated hydrogen peroxide.

  • Patent number: 9268049
    Abstract: An embodiment of the disclosed invention includes a method for attenuating noise during acquisition of marine seismic date. The method includes placing a seismic streamer in a body of water. The seismic streamer includes a streamer body having a length and a channel, a seismic sensor disposed within the channel, and a gel disposed within the channel. The gel has a complex viscosity of at least 50 Pascals and includes a concentration of a polymer between the range of about 5% and about 25% by weight. The method also includes placing a source in the body of water. The seismic streamer and the source are towed through the body of water and the source is fired while being towed through the body of water. Data is collected from the seismic streamer as it is towed through the body of water.

  • Publication number: 20140335425
    Abstract: A polymer that provides for effective proton/cation transfer within, through, across the polymer. The polymer may be used in an electrochemical sensor and may include a redox active species and a facilitator of proton transfer that may provide for the “shuttling”/transfer of a proton through the polymer. As such, the polymer may provide for protons to be transferred through the polymer from or to a conducting substrate. The polymer may also provide for separation of components, fluids, materials in an electrochemical system while still allowing for a transfer, shuttling of protons or cations between the components, fluids or material. The proton, cation transfer polymer may be used in a battery, an electrochemical sensor or a fuel cell.

  • Publication number: 20130227017
    Abstract: Systems and methods for social and data communication that uses physical locations are disclosed. Tagging the data and/or communications to real locations provides that the data is given relevance/context by the tagged location and the data can be searched for/identified by other users using the physical location. By providing/updating the data in real-time, occurrences/interactions in the real world may be mirrored and or enhanced in the virtual world as they occur. Use of location tagging of the data provides for dissemination and/or identification of data by persons who are not “friends” or followers” of the party posting/uploading the data.

  • Publication number: 20130051176
    Abstract: Some embodiments of the disclosed invention include a method for acquiring marine seismic data using solid streamers in a curved pattern. Streamers can be towed in a curved pattern within a body of water. While being towed in the curved patter the source may be fired and response data can be collected by the streamers as they are towed through the water in the curved/circular pattern. These streamers can be solid streamers and can be filled with a gel like substance. Moreover, the streamers can be placed at various known depths within the body of water.

  • Publication number: 20120321809
    Abstract: An anti-biofouling material for use on marine equipment is described, the anti-biofouling material comprising a polymer system comprising a hydrophobically-modified base polymer, the hydrophobically-modified base polymer comprising a base polymer having a backbone and a hydrophobically derivatized chain extender coupled to said backbone of said base polymer, wherein the hydrophobically derivatized chain extender comprises a hydrophobic moiety. The anti-fouling casing comprises a hydrophobic surface that serves to prevent biofouling of the surface.
