Patents by Inventor Maria Auxiliadora Grisanti

Maria Auxiliadora Grisanti 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: 11725468
    Abstract: A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads disposed in a support tube and surrounded by an electrically conductive member such as tightly wound copper threads. In certain embodiments, the electrically conductive member may be provided in direct contact with the support tube without the requirement of an insulating layer. Alternatively, the tube itself may be foregone with a channel for the fiber optic thread or bundle defined by insulating material about the electrically conductive member. Either way, the overall profile of the slickline may advantageously be kept to a minimum.
    Type: Grant

  • Patent number: 10354777
    Abstract: Electrical conductors and processes for making and using same. In some examples, the electrical conductors can include an inner electrically conductive element, which can define a central longitudinal axis. A first polymer layer can be disposed circumferentially about the inner electrically conductive element. A plurality of electrical conductor segments can be disposed about the first polymer layer and spaced around the central longitudinal axis. A second polymer layer can be disposed between the electrical conductor segments. The second polymer layer and the electrical conductor segments together can define a substantially annular cross-sectional area and an outer perimeter surface. An electrical insulator can be disposed about the outer perimeter surface defined by the second polymer layer and the electrical conductor segments.

  • Patent number: 10087717
    Abstract: A dual use cable includes at least one fiber optic cable encased in a metallic component that is encased in a layer of polymer material. The polymer material is surrounded by a tube or armor wire strength members embedded in one or two additional polymer material layers. A final assembly can include an outer metallic component or an outer layer of polymer material. The at least one fiber optic cable transmits data and the armor wire strength members and/or metallic components transmit at least one of electrical power and data.
