  • Publication number: 20240282001
    Abstract: A device, a mapping system, and a method for determining a map of a three-dimensional environment including objects determine common characteristic elements in first and second images of the environment, determine groups of characteristic elements by an image analysis such that each group of characteristic elements corresponds to an object of the environment, estimate a three-dimensional position of the characteristic elements based on a triangulation between positions of the characteristic elements in the first image and positions of the corresponding characteristic elements in the second image, and, for each group of characteristic elements, optimize the three-dimensional positions of the characteristic elements of the respective group by minimizing an error variable which is a function, for all the characteristic elements of the group, of a distance between a detected position of the characteristic elements from at least the first image and a two-dimensional position associated with the corresponding estim

  • Patent number: 11371337
    Abstract: Disclosed is a liner top test tool with a scraper cartridge and seal back-up rings for testing casing integrity in a wellbore. The seal back-up rings are comprised of first and second ring elements that are biased apart by compression springs. The first ring element has a boss that inserts into a bore of the second ring element, blocking debris from flowing into the interior of the seal back-up ring.

  • Publication number: 20080004928
    Abstract: A method for collecting and managing information related to the shipping and condition of a cargo during a cargo voyage from a source to a destination is provided. An electronic cargo voyage folder (ECVF) associated with the cargo is created, including a cargo id, cargo contents and shipping methods for the cargo voyage. At the source a first assessment of an initial cargo condition is requested and the first assessment of the cargo condition, a first place of assessment and a first time of assessment is recorded in the ECVF. The events occurring during the cargo voyage are also recorded in the ECVF. At the destination, a second assessment of the cargo condition is requested and a second assessment of the cargo condition, a second place of assessment and a second time of assessment is recorded in the ECVF.

  • Patent number: 7249553
    Abstract: Described is a process and a plant for destroying rocket motors, including in particular the following steps and stations: cutting of the motor into sections; cooling of the sections containing propellant by immersion in a cryogenic liquid; and fragmenting and extraction of the cooled propellant by elastic deformation of the casing of the section. The propellant fragments are recovered for subsequent treatment and the casings are deactivated before being scrapped.

  • Patent number: 4762050
    Abstract: The annular transmission block (13) is pressed against the transmission face (8) of the cylinder (5) when the oil pressure arrives via the duct (17). At that moment, one of the two grooves (19 or 10) can supply one of the two ducts (9 or 10) in such a way that the oil pressure is transmitted across the fluid-retaining devices (11and 12) to one of the two ends of the chamber (4). The pressure-maintaining device (25) is then charged by stressing its spring (27) and the piston (6) moves into the chamber (4) of the cylinder, carrying along the clamp chuck (7).
