Patents by Inventor Marie-Pascale Chagny

Marie-Pascale Chagny 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: 7064949
    Abstract: A connector includes a base and a connector member with a first end connected to the base and a second end opposite the first end. A first region on the connector member, located adjacent the first end, has a first impedance. A second region on the connector member, located adjacent the second end, has a second impedance greater than the first impedance. When an electro-statically charged device is connected to the connector, the electrostatic charge is dissipated relatively slowly due to initial contact with the second region of increased impedance, lowering the voltage resulting from the connection in order to protect static sensitive circuits coupled to the connector.
    Type: Grant

    Date of Patent: June 20, 2006

  • Patent number: 6873136
    Abstract: In a method and system for generating a regulated direct current (DC) voltage output of a voltage regulator module (VRM) to power a device of the information handling system, an activity input, which is indicative of levels of activity of a processor included in the device, is received by the controller module. The controller module selects a first switching frequency from a plurality of switching frequencies of the VRM. The first switching frequency corresponds to a first level of activity. A charge switch is operable to receive a DC voltage input and generate a switched IDC voltage output having the first switching frequency. A discharge switch is operable to provide a discharge path for the switched DC voltage signal while the charge switch is open. A filter module is operable to filter the first switching frequency from the switched DC voltage output and generate the regulated DC voltage output.
