A process for manufacturing a rubber patch comprising a radiofrequency transponder, the patch having a first layer and a second layer, the method comprising moulding and vulcanizing a first layer, the exterior surface of which comprises a cavity able to receive a radiofrequency transponder, placing a transponder in the cavity, and then placing and vulcanizing a second layer in order to embed the transponder between the two layers.

This disclosure concerns a master model for the production of a mold, comprising: (a) a first part, a second part comprising a textured surface; wherein the first part and the second part are connected.

A system for manufacturing a part that includes a mold, a first fixation component, fixed to the mold, second fixation components, each configured to be fixed to a consolidated laminate sheet, third fixation components, each fixed to the mold. The system also includes tension straps. The first fixation component is configured to attach the consolidated laminate sheet to the mold so that the consolidated laminate sheet does not translationally move relative to the forming surface of the mold. Each one of the second fixation components is configured to attach the tension straps to the consolidated laminate sheet. Each one of the third fixation components is configured to attach the tension straps to the mold so that the tension straps are movable relative to the mold. The system also includes a heating assembly and a strap retraction mechanism, configured to retract the tension strap.

A prosthetic device can be implanted in the corpora cavernosa of a penis with erectile dysfunction. The device being formed by two cylinders that can be inflated with a fluid. The device comprises a variable-length erectable portion formed by a chamber that can be pressurized with a low volume of fluid and is formed between an expandable membrane and an axially extendable and foldable longitudinal rib. The membrane and rib extend between a distal tip element and an intermediate connector from which a shortenable anchoring rod emerges, the rib being a single piece formed by a variable-length distal section, an intermediate section that is foldable and extendable in an axial direction, and a proximal section comprising optimized means for the continuous lateral supply of the fluid to the pressurisable chamber. The device also has an integrated unit for storing and pressurizing the fluid, which can be implanted in the scrotum.

Disclosed is a micro-needle including a tip formed using medicine that penetrates into the skin and melts therein; and at least one guide groove each in a stepped shape inward from the outer surface of the tip, and provided to the tip. The micro-needle configured as above may be used to administer a fixed quantity of medicine within a relatively short period of time. Also, since a guide space stepped based on the tip is provided to a base that supports the tip, a large amount of medicine may easily penetrate into the skin.

A method for extrusion coating or extrusion casting, a polymer sheet (4, 5) produced thereby, a roller (2) for use in extrusion coating or extrusion casting, and an apparatus comprising said roller (2), in which micro- and/or nanostructures provided on the surface of the roller (2) are transferred to the polymer sheet (4, 5), and which is applicable to the extrusion coating or extrusion casting of all types of thermoplastic polymer.

A die comprises a concave die, a blank holder, and a punch passing through the blank holder. The concave die has a first reference surface, a second reference surface that forms the bottom of a concave shape, and an upright surface connecting the first reference surface and the second reference surface. The blank holder has a blank holder surface that sandwiches a prepreg together with the first reference surface. The punch has a punch surface that sandwiches the prepreg together with the second reference surface, and a punch side face that sandwiches the prepreg together with the upright surface. There is a prescribed relationship between R1, which is the radius of curvature of the corner formed by the second reference surface and the upright surface, and R3, which is the radius of curvature of the corner formed by the punch surface and the punch side face.

The disclosure relates to a molding element including a main lamella and two ribs positioned on either side of the main lamella at a certain distance from this main lamella. The ribs are mold-able to grooves in the tread, these ribs including rounded ends. The main lamella includes a cutting edge, the cutting edge making an acute angle. The ribs are curved in their length with a curvature C and in that the lamella is curved with the same curvature C.
