Abstract: Disclosed herein are embodiments of a hearing aid configured to be positioned in an ear canal of a user. The hearing aid includes a number of different structural sections. In certain examples, a middle section includes a rechargeable battery and a substrate carrying one or more electronic components, where the substrate is constructed as a flexible circuit board arranged at the battery, and where the middle section is at least partially encapsulated by a polymer material.

Abstract: A flexible offshore pipe includes a plurality of layers forming an inner pipe structure that includes an innermost sealing sheath. A first and a second tensile armor layer each including helically wound elongate armor elements surround the inner pipe structure. The first and the second tensile armor layer each has a winding pitch length and are cross wound. The pipe includes unbonded length sections and holding length sections. The elongate armor elements of the first tensile armor layer in the unbonded length sections are unbonded to said inner pipe structure and in each holding length section at least one of the elongate armor elements of the first tensile armor layer is more restricted to displacement relative to said inner pipe structure than the elongate armor elements of the first tensile armor layer in the unbonded length sections.

Abstract: A flexible pipe for transporting a fluid in a marine environment. The pipe comprises a liner for confining the fluid, an armoring layer surrounding the liner, and an outer protective sheath surrounding the armoring layer and allowing radial expansion and contraction of the armoring layers. The outer protective sheath comprises at least two protective layers of helically wound composite wires with essentially opposite winding angles and locally held together, providing a relatively flexible yet fixed structure of the outer sheath. The outer sheath is held together in an array of discrete spots or along linear or curved paths. Flexibility is maintained because the stiffness in shear in the wires of adjacent protective layers may be made much larger in areas being locally held together than outside these areas. This allows a change of angles between the wires of two adjacent layers of the outer protective sheath during elongation or shortening of the pipe.

Abstract: A flexible, typically un-bonded, armored pipe, and a method manufacturing a flexible pipe. The pipe has a center axis and comprises an inner liner surrounded by a radial armoring and an axial armoring, the radial and axial armoring each comprising at least one armoring layer of armoring profiles wound with winding angles ?i relative to the center axis. The winding angle of the innermost armoring layer ?innermost is larger than the winding angle of the outermost armoring layer ?outermost. The outer radial armoring layer has sufficient strength and flexibility to prevent prohibitively large radial deformations of underlying axial armoring layers without considerably increasing the radial contact pressure on underlying axial armoring layer. At least one fibrous layer, comprising at least two fibrous cords wound on an underlying layer, surrounds the outermost armoring layer. The flexible pipe is useful in terrestrial and/or subsea transport of fluids at elevated temperature and/or pressures.

Abstract: A pipe structure comprising a length of a flexible pipe connected to an end fitting, the flexible pipe comprising an armour layer and an underlying pipe layer the armour layer, the underlying pipe layer having an outer surface around which armouring wires of an armouring layer are helically wound. The pipe structure provides a coupling between a flexible pipe comprising armouring wires and an end fitting, the coupling exerting a relatively low bending or flexure strain on the wires during normal operation of the flexible pipe. The transition path of an armouring wire between the flexible pipe and the end fitting comprises a straight-line-section between a wire-pipe-exit-point where the wire extends away from its underlying pipe layer and a straight-line-end-point on a support unit of the end fitting where the armouring wire in question has its first tangential point of contact.

Abstract: The invention relates to a pipe structure (10) comprising a length of a flexible pipe connected to an end fitting, the flexible pipe comprising an armour layer (11; 19) and an underlying pipe layer (12; 11) to said armour layer, said underlying pipe layer having an outer surface around which armouring wires (111; 191) of an armouring layer are helically wound. The object of the present invention is to provide a coupling between a flexible pipe comprising armouring wires and an end fitting, the coupling exerting a relatively low bending or flexure strain on the wires during normal operation of the flexible pipe.
