Mark Bergren has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9040757
    Abstract: In one embodiment, the present application discloses methods to selectively synthesize higher alcohols and hydrocarbons useful as fuels and industrial chemicals from syngas and biomass. Ketene and ketonization chemistry along with hydrogenation reactions are used to synthesize fuels and chemicals. In another embodiment, ketene used to form fuels and chemicals may be manufactured from acetic acid which in turn can be synthesized from synthesis gas which is produced from coal, biomass, natural gas, etc.
    Type: Grant
    Filed: March 8, 2013
    Date of Patent: May 26, 2015
    Assignee: PIONEER ENERGY
    Inventors: John Henri, Jan Zygmunt, Mark Bergren, Robert Zubrin

  • Patent number: 6253083
    Abstract: The system for wireless communication connection handoff service addresses the CDMA radio congestion problem from the mobile switching center point of view, thereby providing a unified approach to the problem of access failures for CDMA wireless communication service. In operation, the mobile subscriber station forms a message and forwards it to the mobile switching center to indicate the signal strength of the various base stations that have responded to the access probe. The mobile switching center saves this data for later use when the mobile subscriber station moves out of range of the initially selected base station. The mobile switching center reviews the stored data and, if a CIC is available to one of the identified base stations, the channel is allocated and the stored data is flushed. Thus, the need for another probe sequence is avoided and the initially provided base station signal strength data is reused to process a call handoff.
