Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A method of operating a distributed acoustic sensing (DAS) system and a DAS system are described. The method includes disposing the DAS system to measure acoustic signals in a borehole, positioning a vibration tool at a specified depth in the borehole, and obtaining two or more DAS signals, obtaining at least one of the two or more DAS signals while the vibration tool is activated at a respective specified frequency and a respective specified amplitude. The method also includes calibrating the DAS system based on the two or more DAS signals, and the specified depth, the respective specified frequency, and the respective specified amplitude.

Abstract: A wet connection system including a first connector configured to connect to a first control line. The first connector including at least one first pathway arranged to fluidly communicate with the first control line, and a biased movable plug movable within the first connector; and, a second connector configured to connect to a second control line. The second connector including a second pathway in fluid communication with the second control line and a biased sleeve movable within the second connector; wherein the first and second connectors are each pressure balanced to prevent internal control line pressure. External borehole pressures from moving the plug and sleeve from their biased positions blocking the respective first and second pathways in the disconnected condition of the wet connection system.

Abstract: A wet disconnect system with post disconnection pressure integrity includes a bridge tube. One or more seals on the bridge tube that seal the bridge tube to one or more conductors passing through the bridge tube. A defeatable seal/anchor at the bridge tube sealing an outside surface of the bridge tube to an inside surface of a separate structure. The defeatable seal/anchor being defeatable upon application of an axial load above a threshold.

Abstract: The well condition during gravel packing is monitored and the gravel distribution condition is sent to the surface in real time through the preferred technique of a fiber optic line that wraps around the screens directly or indirectly on a surrounding tube around the screens. The fiber optic line has a breakaway connection that severs when the completion inner string is removed. A production string can then be run in to tag the fiber optic line through a wet connect to continue monitoring well conditions in the production phase. The fiber optic line can also be coiled above the packer so that relative movement of the inner string to the set packer can be detected and communicated to the surface in real time so as to know that the crossover has been moved the proper distance to, for example, get it from the gravel packing position to the reverse out position.

Abstract: A concrete dispensing apparatus is used in a manufacturing process for producing pre-cast concrete structures, which are conventionally used to form a foundation for a residential or commercial building. The dispensing apparatus includes a hopper that funnels to a discharge opening extending along the entire transverse length of the dispensing apparatus. A plurality of individually controlled gates cover the entire discharge opening for selectively controlling the length and location of the discharge opening through which concrete is dispensed. The dispensing apparatus also includes a finishing mechanism including a vibratory screed and a rotational finishing roller. The form can be moved relative to the dispensing apparatus or vice versa. A form vibrator induces a vibratory motion into the form to remove air from the dispensed concrete mixture.

Abstract: A segmented auger mechanism is mounted in the hopper of a concrete dispensing apparatus used to distribute a hydrated concrete mixture into a horizontally disposed form to manufacture pre-cast concrete structures, such as concrete wall panels used to form a foundation for a residential or commercial building. The auger mechanism is formed of connected segments that can be individually and independently removed from the concrete structure for service and repair. The auger is rotatably supported by a pair of end bearings supported on the opposing end walls of the hopper of the dispensing apparatus, and by at least one interior bearing rotatably supporting a jack shaft having opposing half-round connecting portions for attachment to a corresponding connecting portion on the auger shaft. Removal of a segment of the auger mechanism facilitates the removal of the entire auger mechanism to minimize the down time of the concrete dispensing apparatus.
