Patents by Inventor David Gimenez Rocamora

David Gimenez Rocamora 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).

  • Dual transformer communication interface
    Patent number: 9705562
    Abstract: A power line communication device comprises a plurality of transformers in series. These transformers are used to increase the voltage of a digitally encoded signal in a stepwise fashion prior to being coupled into a power line. While a transmit path includes at least a first transformer and a second transformer in series, a receive path may include only one of these two transformers. For example a receive path may include only the first transformer, or include the first transformer and a third transformer. The net ratio of voltage increase and decrease may be different in the transmit and receive paths.
    Type: Grant

    Date of Patent: July 11, 2017
    Assignee: BROADCOM EUROPE LIMITED

  • External AC-DC coupling for communication interfaces
    Patent number: 8232666
    Abstract: A power line communication device comprises a plurality of transformers in series. These transformers are used to increase the voltage of a digitally encoded signal in a stepwise fashion prior to being coupled into a power line. While a transmit path includes at least a first transformer and a second transformer in series, a receive path may include only one of these two transformers. For example a receive path may include only the first transformer, or include the first transformer and a third transformer. The net ratio of voltage increase and decrease may be different in the transmit and receive paths. Additionally, the communication interface can be disposed within an AC/DC converter or distributed among an AC/DC converter and an appliance attached thereto.
