Abstract: Methods and systems are provided for a spark plug of an internal combustion engine. In one example, a spark plug includes a housing section having a first groove and an opposing, second groove. A tool including a first protrusion and second protrusion may couple with the first and second grooves of the spark plug in order to drive the spark plug to either of only two coupled positions with a cylinder head.

Abstract: A network diagnostic system may include one or more network diagnostic components. The network diagnostic components may be configured to capture at least a portion of one or more network messages. The network diagnostic components may include a plurality of buffers, and the network diagnostic components may be configured to capture at least a portion of one or more network messages in the buffers. The network diagnostic components may be configured to execute the captures in response to capture trigger. A trigger module may be configured to provide the capture trigger in response to detecting one or more conditions. The trigger module may be configured to provide the capture trigger in response to detecting a statistic that is outside a particular range of values. The trigger module may be configured to provide the capture trigger in response to detecting a change in network configuration data associated with a networking system.

Abstract: In one example, an optical network access switch includes independent first and second banks of individually selectable optical inputs, as well as independent first and second groups of individually controllable optical outputs. A first multiplexer is connected to the optical inputs of the first bank and the optical outputs of the first group, and a second multiplexer is connected to the optical inputs of the second bank and the optical outputs of the second group. Finally, a configuration interface communicates with the first and second multiplexers and receives a switching command which specifies the connection/disconnection of an optical output to/from an optical input.

Abstract: A network tap device array capable of being powered by a power-over Ethernet (“POE”) supply is disclosed. The array enables data from multiple nodes in a communications network to be tapped and forwarded to a plurality of monitoring devices. In one embodiment the network tap device array includes a chassis that is configured to receive a plurality of network tap devices that are each powered by a POE supply. Each network tap device includes network ports for receiving and transmitting network data via communication cables and tap ports for forwarding the tapped network data to the monitoring device. In another embodiment, a sub-chassis includes a plurality of network tap devices and an aggregator that aggregates tapped data from each of the tap devices. The aggregator then forwards the aggregated data to the monitoring device. The sub-chassis can be included in a chassis that is configured to receive multiple populated chassis.

Abstract: A network tap device that is configured for operation in a copper Gigabit Ethernet communications network using a power-over-Ethernet (“POE”) electrical supply is disclosed. In one embodiment, a network tap device powered by a POE supply is disclosed, comprising first and second network ports that are configured with receptacles for receiving communication cables. The communication cables are configured to carry both data signals and the POE supply to and from the network tap device. The network tap device further includes first and second tap ports that connect with additional communication cables to a monitoring device. The network tap device also includes control and regulation circuitry that is configured to receive the POE supply from the communication cables via the network ports and to enable components of the network tap device to be operated by the POE supply.

Abstract: Interposers for tapping a signal. An interposer can include an interposer printed circuit board, an output connector that couples the interposer circuit board with a backplane connector of a chassis, an input connector for coupling the interposer circuit board with a disk drive, tapping circuitry for tapping a high-speed differential signal, and connectors coupled to the tapping circuitry for transmitting the tapped signal to an analyzer or an oscilloscope.

Abstract: The present invention provides an adapter for enabling a host device having an electrical connector compatible with a first protocol that is not connectable with a connector assembly associated with a second protocol to be usable with the second protocol. The adapter includes a printed circuit board having a first end and a second end. The first end includes a first interface formed to removably connect with an electrical connector associated with a first protocol. The second end includes a second interface formed to removably connect with a connector assembly associated with the second protocol. A method of making the adapter includes configuring the first interface on the printed circuit board and integrating the second interface with the printed circuit board. One embodiment includes an adapter for enabling a host device with SFP electrical connectors to be usable with an SAS/SATA protocol.

Abstract: Blends of synthetic olefins for use as the continuous phase of fluids selected from the group consisting of drilling, drill-in, and completion fluids. The blends meet EPA discharge requirements while also permitting investigators to clearly discern the presence and quantity of biological markers in reservoir fluid samples—particularly pristane and phytane.

Abstract: The present invention provides for network taps capable of connecting to a plurality of communication cables. The network taps provide one or more levels of multiplexers which allow network data signals from a particular communication cable to be delivered to an attached device in order to monitor the activity of the communication cable. The network taps also include integrated circuitry which control the various functions and components of the network tap.
