Marcelo Carrera 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: 9906550
    Abstract: A network is protected from e-mail viruses through the use of a sacrificial server. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.
    Type: Grant

  • Patent number: 7913078
    Abstract: A network is protected from viruses through the use of a sacrificial server, which may be physical or virtual. Any executable programs or other suspicious parts of incoming e-mail messages are forwarded to a sacrificial server, where they are converted to non-executable format such as Adobe Acrobat PDF and sent to the recipient. The sacrificial server is then checked for virus activity. After the execution is completed, the sacrificial server is rebooted.

  • Patent number: 6204722
    Abstract: An electronic circuit generates a stable voltage signal for the polarization during a reading step of a UPROM redundancy cell incorporating at least one memory element of EPROM or Flash type, having at least one terminal to be polarized, and MOS transistors which connect such memory element to a low voltage power supply reference. The circuit includes a current mirror structure with a first control branch and a second output branch. The current mirror stricture includes a first series of MOS transistors (M2, M3, M4) in said first branch between the supply reference and a ground; and a second series of transistors (M5, M6, M7) in said second branch. The circuit also includes an input terminal connected to the gate terminal of a transistor of the first series of transistors and an output terminal corresponding to an interconnection node of the second series of transistors. The stable voltage is obtained through a current which passes through at least a pair of transistors of the second series.
