  • Patent number: 10277713
    Abstract: Information identifying a user as having accessed a first network device from an external network connected device is received at an intermediate network connected device from an edge network device. The intermediate network connected device is arranged between the first network device and a second network device. The intermediate network connected device, the first network device and the second network device are within the network and the external network connected device is outside the network. A request to access the second network device is received at the intermediate network connected device from the first network device. It is determined that the user is a source of the request via the first network device based upon the received information. The request from the first network device is evaluated based upon determining the user is the source of the request.

  • Patent number: 9431651
    Abstract: A composite material for a lithium ion battery anode and a method of producing the same is disclosed, wherein the composite material comprises a porous electrode composite material. Pores with carbon-based material forming at the pore wall are created in situ. The porous electrode composite material provide space to accommodate volumetric changes during battery charging and discharging while the carbon-based material improved the conductivity of the electrode composite material. The method creates pores to have a denser carbon content inside the pores and a wider mouth of the pores to enhance lithium ion distribution.

  • Patent number: 8911179
    Abstract: The invention relates to a jack-up rig. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the jack-up rig comprises at least two derricks.

  • Patent number: 8888410
    Abstract: A single heavy lift system is made of modular units, each of which has a pair of supporting legs carrying a transverse beam therebetween. The beam is engaged to the supporting legs through jackup units that allow the transverse beams of several modular units move in unison and thus increase lifting capacity of the system. The modular units can be formed as modular, self-propelled units, transported to the site, where the lifting task is to be performed if necessary. The system can be positioned in a dry dock or offshore.

  • Publication number: 20130101357
    Abstract: The invention relates to an ice worthy jack-up rig that may extend the drilling season in shallow water off shore Arctic or ice prone locations. The inventive rig would work like a conventional jack-up rig while in open water with the hull jacked up out of the water. However, in the event of ice conditions, the hull is lowered into the water into an ice defensive configuration. The hull is specifically shaped with a lower portion that is an ice-bending surface to bend and break up ice that comes in contact with the hull while in the ice defensive configuration. Furthermore, the ice worthy jack-up rig that comprises at least two derricks so as to double the exploration efficiency and lower the relating costs.
