  • Patent number: 10822940
    Abstract: An intelligent tool bus network for a bottom hole assembly (BHA) that can enumerate the nodes on the bus to build a tool string layout map. During the enumeration, an enumeration master node (EMN) sequentially powers and tests additional sections of the bus and additional tool electronics. At each node, the EMN records the results of the tests in an enumeration log. For each good node, communication is established with the EMN to retrieve a node ID and node metadata. Using the enumeration log, the EMN builds a tool string layout map that includes information of each node, their relative location, and their operating status. The intelligent tool bus network also facilitates sectioning a bus into a plurality of sub-busses upon a sectioning event and rejoining the sub-busses. The sectioning event occurs as a result of a fault on the bus or a planned section division multiplexing event.

The structure is configured to detect and analyze the type of external noise, and to use information about the noise type (such as noise level, frequency range of noise, noise source) to improve signal quality and usability of the bio signal. Different algorithms can be used for each noise type detected. In some example cases, for instance, the structure is configured to at least one of extract noise from measurement signal, synchronize measurement with noise signal, change the software filter or analysis algorithm, change gain/filter settings of noise mitigation circuitry, and prompt user to assist as needed, based on the detected noise. Bad signal epochs can be discarded prior to recording, to efficiently use storage. Separate channel(s)/sensor(s) can be used, with different filtering/gain schemes, for noise detection.

  • Patent number: 9645266
    Abstract: The resonant frequency of an example transducer can be adjusted by changing the effective mass of a backing mass using a tuning module. The tuning module includes a electrical source, a switch, and an electromagnetic coil connected in series as an electrical circuit. The electromagnetic coil is mechanically attached to the backing mass, and is disposed within a reservoir of a magneto-rheological fluid enclosed within a casing. When the switch is closed, the electrical source applies a voltage and current to the electromagnetic coil, and induces a localized magnetic field within the magneto-rheological fluid. In response to this localized magnetic field, the magneto-rheological fluid increases in viscosity, assumes properties comparable to a viscoelastic solid, and become affixed to the electromagnetic coil. As the electromagnetic coil is mechanically attached to the backing mass, the solidified magneto-rheological fluid increases the effective mass of the backing mass.

  • Patent number: 9534486
    Abstract: Time is tracked in a downhole tool to indicate whether timestamps associated with data samples or events in a log indicate either real time or a duration of time since a certain reset, and to indicate whether the timestamps have been synchronized with a master clock in the tool. The log also records the time and offset of each synchronization event. A computer processes the log to convert all of the timestamps to real-time values and to indicate timestamps that have been estimated and timestamps that were never synchronized to a master clock in the tool. The computer determines an associated uncertainty for each of the estimated timestamps.

  • Patent number: 9291049
    Abstract: A measurement-while-drilling (MWD) telemetry system comprises a downhole MWD telemetry tool comprising a mud pulse (MP) telemetry unit and an electromagnetic (EM) telemetry unit. The MWD telemetry tool can be configured to transmit data in an EM-only telemetry mode using only the EM telemetry unit, in an MP-only mode using only the MP telemetry unit, or in a concurrent telemetry mode using both the EM and MP telemetry units concurrently. When transmitting data in the concurrent telemetry mode, the telemetry tool can be configured to transmit in a concurrent confirmation mode wherein the same telemetry data is transmitted by each of the EM and MP telemetry units, or in a concurrent shared mode wherein some of the telemetry data is transmitted by the EM telemetry unit, and the rest of the telemetry data is transmitted by the MP telemetry unit. The telemetry tool can be programmed to change its operating telemetry mode in response to a downlink command sent by an operator at surface.
