Abstract: Systems, methods and computer readable medium that are configured to perform blockchain ledger operations. A private blockchain network is implemented in connection with other features such as access to the ledger or portions of ledge information to verify accuracy. The system can include integration with user computer devices wherein the system implements rules on servers such as behind the private blockchain (e.g., as opposed to just on personal computer devices). The behind the blockchain servers can process access and use of the blockchain. The system can include multiple parallel rules engines.

Abstract: Apparatus for wellbore logging and method of use are provided for measurement of the annular materials interposed between the logging tool and formation and the apparent formation bulk density in open-hole, cased-hole or other conduit. The logging tool can be centralized in the borehole. Non-collimated gamma radiation is emitted into the surrounding media and the amount of radiation which returns to the tool is measured by multiple omni-directional detectors spaced a pre-set distances from the source to provide multiple radial depths of investigation. The annular thickness and density of materials interposed between the logging tool and the formation may be determined from the detector responses and be used to derive the apparent formation bulk density.

Abstract: A connectivity monitor/controller. A wireless connection is established between a mobile device and a docking station that also communicates with external device(s) each configured to selectably communicate with the mobile device via a connectivity through the docking station or through a direct connection with the mobile device. The docking station receives a connectivity assignment specifying external device(s) and a respective connectivity between the mobile device and the specified external device. Each specified connectivity is established based on the connectivity assignment. A display indicating a connectivity configuration including an indication of each specified external device and an indication of each external device's respective connectivity is generated, where the indication of the respective connectivity indicates either a connectivity through the docking station or a direct connectivity, or both.

Abstract: In computing environments that use virtual addresses (or other indirectly usable addresses) to access memory, the virtual addresses are translated to absolute addresses (or other directly usable addresses) prior to accessing memory. To facilitate memory access, however, address translation is omitted in certain circumstances, including when the data to be accessed is within the same unit of memory as the instruction accessing the data. In this case, the absolute address of the data is derived from the absolute address of the instruction, thus avoiding address translation for the data. Further, in some circumstances, access checking for the data is also omitted.

Abstract: Native code corresponding to an invalidated trace is re-used in a system emulator. A first trace is identified. A dropped second trace is identified. The dropped second trace is associated with a first native code for emulating the second trace. If the identified first trace corresponds to the dropped second trace, the first native code is associated to the first trace, and the first native code is executed. If the identified first trace does not correspond to the dropped second trace, a second native code for emulating the first trace is created, the second native code is associated with the first trace, and the second native code is executed.

Abstract: In an embodiment, a network router includes plural interfaces and a chain walker which, upon receipt of a first protocol packet in a first interface, processes the packet by walking the packet through a decapsulation chain associated with the interface and the first protocol and an encapsulation chain associated with an identified second interface and identified second protocol. The walker passes the packet to elements of the decapsulation chain to produce a decapsulated packet. The walker passes the decapsulated packet to elements of an encapsulation chain to produce an encapsulated packet. Each chain includes at least one packet-processing element. An element receives the packet from the walker as processed by a previous element, the packet being further processed as appropriate. The walker, upon receipt of the first protocol packet, passes the packet to elements of a demultiplexer chain associated with the first interface to produce a demultiplexed packet.

Abstract: In connection with a downhole density logging method and tool, the gamma ray source and detectors are substantially non-shielded (that is, they are omni-directional). As a result the gamma ray emission produced by the ‘omni-directional’ source is non-collimated and the back-scattered gamma rays counted by the omni-directional detectors are also non-collimated. Testing has shown that density logging through well casing is viable using this system.

Abstract: A method for processing packets in a router includes specifying operations on packets as chains of processing elements. Each chain is uniquely associated with one interface/protocol pair, and each processing element performs at least one function on a packet. An incoming packet is received, and processed, first by a demultiplexor element which determines the protocol of the next higher level used by the packet. Then, the packet is processed by the elements of a decapsulation chain associated with the interface on which the packet was received, and by the elements of an encapsulation chain associated with the interface on which the packet is to be transmitted. The demultiplexor element or operation passes the packet on to a decapsulation chain associated with the protocol and with the incoming interface, depending on protocol information contained in the incoming packet.
