Abstract: Gas quantity in a pixel may be estimated based on spectral matched filtering. Image data associated with a scene may be received. The scene may comprise a plurality of pixels. Next, a spectral matched filter may be constructed for a predetermined gas and based on the image data. A quantity of the predetermined gas may then be estimated in at least one of the plurality of pixels by applying the spectral matched filter to the image data.

Abstract: A wireless communication device can include a communication control interface. Beamforming circuitry coupled to the communication control interface receives, over the communication control interface, an index value into a coarse codebook and an offset vector. The index value indicates a value within the coarse codebook, and the offset vector indicates an offset value for a desired beam relative to the index value. The beamforming circuitry determines a new beam direction based on the index value and the offset vector using one of interpolation and extrapolation.

Abstract: A method of providing transformed target points for integrating a component into an assembly includes collecting a set of component target points, collecting a set of assembly target points, identifying target points common to the set of component target points and the set of assembly target points; performing a specified number of Monte Carlo transformations of selected ones of the common target points to yield a set of transformed target points and vectors and an associated uncertainty value for each transformed target point and vector, and using certain ones of the transformed target points for integrating the component into the assembly based on the associated uncertainty value for each of the transformed target points.

Abstract: A well intervention apparatus including a base frame assembly, a deck attached to an upper end of the base frame assembly. The deck includes a passage and a hatch adjacent to the passage. A track is disposed within the passage, and a movable plate is slidingly attached to the track for movement within the passage. A reception plate is attached over a first aperture of the moveable plate and a tower is mounted over a second aperture of the moveable plate. A primary hoist assembly is connected to an upper end of the tower. The reception plate is configured to secure a first well intervention tool, and the primary hoist assembly is configured to suspend a second well intervention tool from the tower. In a first position of the moveable plate, the reception plate is disposed over the well. In a second position, the tower is disposed over the well.

Abstract: The invention relates to an optical fiber comprising a core and a cladding, wherein the core is made of a glass composition having a near-zero electrostrictive coefficient M11, to reduce the effect of stimulated Brillouin Scattering (SBS). The invention further relates to a compensation fiber segment for connection to a silica optical fiber, the compensation fiber segment being made of a glass composition having an electrostrictive coefficient that opposes that of the silica optical fiber so that an acoustic wave transmitted to compensation fiber segment from the silica optical fiber will generate an acoustic wave within the compensation fiber segment that is about 180 degrees out of phase with the that acoustic wave transmitted from the silica optical fiber, thereby minimizing the effect of stimulated Brillouin Scattering.
