Patent number: 8793114Abstract: A method and system dynamically generates virtualized configurations of sensors and signals used in drilling system equipment. The virtualized configurations may be used for novel operational testing of automation systems on drilling rigs. The methods and systems may be configured to virtualize actual drill floor equipment in order to have enhanced fault coverage of the automation systems. A control network that is a component of the automation systems may implement a testing loop that accommodates virtualized equipment in a manner substantially similar to actual equipment. In this manner, the testing loop may be configured to control elements specific to the equipment under control, and generate testing results for those specific control elements.Type: GrantFiled: October 21, 2011Date of Patent: July 29, 2014Assignee: Athens Group Holdings LLCInventors: Donald F. Shafer, Mark Price, William T. O'Grady, Jr., Nestor Fesas

Patent number: 7248877Abstract: A multiple access wireless communications architecture provides selective, simultaneous communications with wireless devices located in different sections of a spatial area around a communications apparatus referred to as “sectors”. This includes communications between wireless devices in a single sector, between wireless devices in different sectors and between wireless devices and a wired network or wireless backhaul network. The wireless communications architecture generally includes two or more wireless antenna arrangements that are each configured to provide communications with wireless devices located in a particular sector. Each wireless antenna arrangement is further configured to determine whether signals are being communicated on a communications channel before transmitting on the communications channel. This may be implemented, for example, using a carrier sense or energy detection mechanism.Type: GrantFiled: July 7, 2003Date of Patent: July 24, 2007Assignee: Bandspeed, Inc.Inventors: Efstratios Skafidas, Ben Jones, Antonio Torrini, John Jack Morton, Eric Crawford, Mike Gibson, William John Rinderknecht, Mark William Benson, Neil Patrick Kelly, Nestor Fesas, Michael Casey Luther, Blaine Kohl

Patent number: 6516352Abstract: A system and method for dynamically switching between different physical layer devices (PHYs) in a network interface. The system comprises a network interface in a network device, e.g., a network card in a computer system which includes a first PHY device and a second PHY device. The first PHY device is coupled to a first transmission medium (such as fiber-optic cable) which requires a continuous connection to the computer system when active. For a SERDES device, this continuous connection is required because the PHY needs constant access to its physical coding sublayer (PCS), which is located external to the PHY. The second PHY device is coupled to a second transmission medium (such as copper cable) which does not require this continuous connection. This second PHY may be, for example, a G/MII device, which includes the PCS internally. The network interface card further includes a link switching unit, a physical layer interface unit, and a control unit.Type: GrantFiled: August 17, 1998Date of Patent: February 4, 2003Assignee: Intel CorporationInventors: Bradley J. Booth, Nestor A. Fesas, Jr., Robert O. Sharp, William Kass

Patent number: 6397316Abstract: The present invention provides a method and an apparatus for transferring data between a computer system and a network interface card that avoids virtual-to-physical address translations. The computer system allocates blocks of memory during system initialization for storing data in transit between the computer system and the NIC, and the physical addresses of these blocks of memory are stored in a table on the NIC. Consequently, address conversion is performed only once, when the memory is allocated. When a request to transfer data to the NIC is received from the upper layers, the device driver copies the data from the upper layers into the next available memory block. The device driver then formats a command and passes it to the NIC for processing. Data transfer commands are communicated to the NIC through a packet descriptor command (PDC), which is a 32-bit value subdivided into fields that completely describe the data transfer operation.Type: GrantFiled: July 24, 1997Date of Patent: May 28, 2002Assignee: Intel CorporationInventor: Nestor A.
