Abstract: In a first scenario, nested darts provide pressure isolation between a space inside a liner assembly below an expansion cone and a well annulus. Increased pressure in this space can be used to push the expansion cone upward and assist the bottom-up expansion of a liner hanger provided at the top of the liner assembly. In a second scenario, an obstruction lands on a seat provided in a seat assembly. Pressure in a space located between the expansion cone and the seat assembly is increased such that an upward force acts on the expansion cone to expand the liner hanger. The second scenario may be utilized by itself. Alternatively, the second scenario may be utilized as a contingency method if the first scenario has failed.

Abstract: A string includes a pipe that is connected to an expansion mechanism and a retrieval tool that is connected to the pipe above the expansion mechanism. The retrieval tool includes a carrier that can selectively latch on an expandable liner and one or more actuators. The retrieval tool can ensure latching of the carrier while the expandable liner is above the Blow-out Preventer. The retrieval tool can prevent accidental latching of the carrier on the expandable liner during the expansion of the liner. By manipulating the pipe, the retrieval tool can force the carrier's release from the expandable liner.

Abstract: Captured vocals may be automatically transformed using advanced digital signal processing techniques that provide captivating applications, and even purpose-built devices, in which mere novice user-musicians may generate, audibly render and share musical performances. In some cases, the automated transformations allow spoken vocals to be segmented, arranged, temporally aligned with a target rhythm, meter or accompanying backing tracks and pitch corrected in accord with a score or note sequence. Speech-to-song music applications are one such example. In some cases, spoken vocals may be transformed in accord with musical genres such as rap using automated segmentation and temporal alignment techniques, often without pitch correction. Such applications, which may employ different signal processing and different automated transformations, may nonetheless be understood as speech-to-rap variations on the theme.

Abstract: A tool for expanding a liner in a wellbore includes a cone assembly that is moveable between a retracted position and an extended position. The tool also includes a jack assembly that is operable by fluid pressure to move the cone assembly from the retracted position to the extended position. The fluid pressure is also applied to expansion cup seals to generate axial load that urges the cone assembly to move through the expandable liner and radially expand of the expandable liner. A latch assembly axially fixes the liner while the cone assembly moves to the extended position. Once the cone assembly is fully moved to the extended position, the latch assembly releases the liner, allowing the cone assembly to move through the liner and radially expand the liner.

Abstract: An expandable sleeve is used for providing support to an obturation member. The expandable sleeve and the obturation member form a hydraulic isolation in a casing. The expandable sleeve has preferably a small thickness or cross-section, which can allow for a large flow-through inner diameter after expansion. Also, the expandable sleeve is preferably short. Thus, mill-up operations that are performed when the expandable sleeve is no longer in use can be expedited or even eliminated in some cases.

Abstract: There is provided an integrated-optic transmitter for transmitting light pulses to a further optical apparatus for generating a quantum cryptographic key according to at least one quantum cryptography technique. There is also provided an integrated-optic receiver for generating a quantum cryptographic key from light pulses received from a further optical apparatus. The transmitter apparatus splits incoming light into two paths to temporally separate the split light pulses and controls the output intensity of each split pulse as well as the phase of at least one of the split pulses. The receiver apparatus receives first and second light pulses and controls the output intensity of each said pulse between a first and a second optical detector. The light input into the second detector passes through an integrated element that controls the amount of light output into two paths that recombine before at least a portion is output to the second detector.

Abstract: In accordance with an embodiment, a method is disclosed for detecting action in a video clip. An audio clip is extracted from the video clip. The audio clip is converted to an auditory spectrogram. The auditory spectrogram is used to construct a self-similarity matrix. The self-similarity matrix is then used to calculate a novelty curve. The clip is then segmented into segments according to peaks in the novelty curve. Each of segments is scored, and then classified as an action clip if the score is above or below a predetermined threshold. Related methods for folding a digitized song into a shorter version of itself and for sequencing a set of user-supplied video and photo clips to a user-supplied song are further disclosed.
