A method of making a case for a mobile device with a screen. The method comprising 3D printing of the case in a partially finished form on a support surface in a configuration in which rear wall (1) and sidewalls (2-5) lie alongside one another on the surface, and folding the sidewalls up relative to the rear wall to at least partially create a cavity for the device. Separate corner portions (10, 11) may be provided to connect the sidewalls. The invention also extends to a 3D printed blank from which the case is formed.

A deployable Kiriform flexure includes first and second sections. The first section of the Kiriform flexure includes a plurality of curved fins arranged about a central axis. The second section of the Kiriform flexure includes a plurality of curved fins arranged about a central axis. Each fin of the second section is joined with a fin of the first section such that the first and second sections share a common central axis in a configuration that produces out-of-plane elastic buckling of the fins to actuate the Kiriform flexure from a substantially flat structure that extends substantially only in two dimensions orthogonal to the central axis to an expanded structure extending substantially in a third dimension parallel to the central axis when at least one of the first and second sections is rotated relative to the other section.

An inflatable sleeve including one or more tubular portions including zones having different dimensions (e.g. thickness and/or diameter) and/or physical properties (e.g. elastic modulus) to enable control over the inflation characteristics of each zone, and a method of manufacturing same. The present invention further relates to a pipe junction sealing packer incorporating such an inflatable sleeve.

A display module is disclosed. The display module includes a planar display area and a curved display area bending and extending from an edge of the planar display area. The display module includes a curved cover plate, a flexible display panel attached to the curved cover plate, and a backplate. The backplate includes a thinning part, and a thickness of the thinning part is gradually reduced from an edge area of the planar display area to the curved display area. The present disclosure can reduce forces undergone by the flexible display panel in the curved display area and prevent curved sides of the flexible display panel from having a cracking risk.

A method of forming a structural honeycomb includes cutting and folding a substrate sheet according to predetermined cutting and folding patterns and fold angles that cause the sheet to form a honeycomb having cells that each have at least one face abutting, or nearly abutting, the face of another cell. The honeycomb is then stabilized by joining abutting, or nearly abutting, faces to hold the honeycomb together. The honeycomb may have a prespecified three-dimensional shape. The folding pattern may include corrugation, canted corrugation, or zig-zag folds. Joining may employ fixed and/or reversible joinery, including slotted cross section, tabbed strip, angled strip, integral skin, sewn, or laced. At least some folds may be partially-closed to create bends and twists in the honeycomb structure. Some surfaces of the honeycomb may be covered with a skin or face sheet. The substrate sheet may have flexible electronic traces.

An apparatus for molding a pouch, the pouch having a first seating part and a second seating part, that are connected to each other, the pouch being configured such that when an electrode assembly is mounted and sealed therein, the first seating part and the second seating part are folded to cover top and bottom surfaces of the electrode assembly, and the first seating part and the second seating part are in contact with each other. The apparatus includes, a lower mold in which a first groove recessed by a predetermined depth from a top surface thereof is formed, and a second groove is additionally recessed from a bottom surface of the first grove; and an upper mold on which a flat portion is formed on one surface thereof, which is inserted into the first groove, and a protrusion inserted into the second groove protrudes from the flat portion.

Elasticized absorbent articles containing weakened elasticized portions and methods of manufacture are disclosed. A method comprises applying a first amount of adhesive to a first portion of at least one of the first web of material and the elastic strand, applying a second amount of adhesive to a second portion of at least one of the first web of material and the elastic strand, covering the elastic strand with either the first surface of the first web of material or a first surface of a second web of material to form an elasticized web. The elasticized web comprises a heavy bonding region and a light bonding region, wherein the heavy bonding region comprises a greater area density of adhesive than the light bond region. Finally, the method may further comprise partially weakening the waist panel elastic strand at least at one location within the second region.
