  • PHOTO-REALISTIC INFRASTRUCTURE INSPECTION
    Publication number: 20220028054
    Abstract: One aspect provides a modular inspection robot for inspecting vertical shafts, chambers or tunnels. An embodiment provides related methods and products. One method includes: capturing, using a plurality of video cameras associated with an infrastructure inspection unit, two or more videos of infrastructure; accessing, using one or more processors, image metadata indicating a mesh of connected vertices based on the two or more videos; selecting, using the one or more processors, image data of frames of the two or more videos for inclusion in an output based on the mesh; and outputting, using the one or more processors, a photo-realistic image of the infrastructure comprising the image data selected. Other examples are described and claimed.

  • Production of optically active 2-substituted tetrahydropyran-4-ones
    Patent number: 6680183
    Abstract: Optically active 2-substituted tetrahydropyran-4-ols or esters thereof may be prepared using esterases or hydrolases from the corresponding racemic mixtures of esters or alcohols. This provides a route to the corresponding optically active ketones. The racemic mixtures are preferably in the cis-form. such mixtures may be produced by reacting but-3-ene-1-ol with an aldehyde in the presence of an acid.
