Abstract: Provided is a method for facilitating the renewing of a digital identity document. It includes receiving a request for renewing a digital identity document; checking whether said digital identity document can be renewed, if the check result is positive, creating an up-to-date validity-related data item to be associated with said digital identity document and to be inspected by a verifier when the validity of said digital identity document must be assessed; and sending said up-to-date validity-related data item to a device of a user of said digital identity document so that a validity-related data item previously associated with said digital identity document can be replaced by said up-to-date validity-related data item at the user's side.

Abstract: A method is provided for the multi-axis shaping of a hollow workpiece, such as a polygonal hollow workpiece. The hollow space of the workpiece has introduced into it a supporting core, which has a central body with at least two differently oriented, inter-communicating cylinder bores and also has pistons, which are accommodated in the cylinder bores and can be subjected to the action of pressure fluid through a fluid connection of the central body. Prior to the radial shaping of the workpiece in a radial press, in a process in which at least two radial dimensions are to be decreased, the supporting core is expanded radially, with the pistons being extended out of the cylinder bores by the pistons being subjected to the action of pressure fluid.

Abstract: A radial press has at least six main jaws arranged concentrically and uniformly about a press axis to be moved radially in the direction of and away from the press axis by a drive unit. Each main jaw has a contact surface radially inwards and mechanical holding means for press jaws that can be attached in an exchangeable manner. A cutting tool is received in a tool installation area delimited outwardly by the main jaws. The cutting tool has multiple cutting attachments, each of which is attached to a main jaw and has a base structure. At least one of the cutting attachments has a cutting structure. Each base structure has a support surface which rests against the contact surface of the paired main jaw and at least one engagement element. The cutting structure protrudes from the paired base structure in the direction of the press axis.

Abstract: Methods and apparatus for analyzing nested tubulars via electromagnetic (EM) logging. An example method includes operating an EM logging tool within tubulars nested within a wellbore. The EM logging tool includes an EM transmitter and multiple EM receivers. Data obtained via the EM receivers is utilized to estimate an individual thickness of each tubular at each of multiple depths within the wellbore. The estimated individual thicknesses are utilized to estimate a cumulative thickness of the tubulars at each depth. Local variations of the estimated cumulative thicknesses are utilized to distinguish between actual and spurious indications of differences between the estimated individual thicknesses at neighboring depths.

Abstract: A magnetic core having an inner core and one or more bundles of stacked magnetic strips arranged over the length of the inner core generates an increased magnetic field with limited saturation. The magnetic strips may include silicon-iron, iron cobalt, or combinations thereof. A method of manufacturing the core includes providing a plurality of magnetic strips each having a length longer than a width, coupling the plurality of magnetic strips along one length of each of the plurality of magnetic strips, and shaping the plurality of magnetic strips partially or fully around an inner circumference.

Abstract: A tangible, non-transitory, machine-readable medium, includes machine-readable instructions to obtain a measurement relating to a first metal thickness of a casing by passing a transmitter and a receiver of an electromagnetic logging tool over a defect. The tangible, non-transitory, machine-readable medium, also includes machine-readable instructions to obtain a ghosting kernel of the electromagnetic logging tool including a response of the electromagnetic logging tool to a localized change in metal thickness from the first metal thickness of the casing to a second metal thickness, wherein the second thickness is different from the first metal thickness. The tangible, non-transitory, machine-readable medium, further includes machine-readable instructions to determine the metal thickness of the casing at the defect based on the measurement and the ghosting kernel of the electromagnetic logging tool.
