A method for sensing intensity of laser light in a simultaneous laser welding system includes placing a smart part in a weld area. The smart part includes at least a laser light intensity sensor for sensing laser light directed at it. Laser light intensity is sensed by the laser light intensity sensor of the smart part which provides an output signal indicative thereof to a controller.

This invention describes a 3-layer insulation material (10) comprising a first fabric layer (12), a second fabric layer (14) and a third fluted intermediate fabric layer (16) between the first and the second fabric layers (12, 14), the fluted intermediate fabric layer (16) being attached alternately to the first and the second fabric layer (12, 14) with longitudinal seams (18a-18n) forming longitudinal channels (20a-20n) for the insulation material (22) having individual insulation material (22) bundle in-side each longitudinal channel (20a-20n). Also disclosed are a method and an arrangement for producing the same.

A method of making a flowcell includes bonding a first surface of an organic solid support to a surface of a first inorganic solid support via a first bonding layer, wherein the organic solid support includes a plurality of elongated cutouts. The method further includes bonding a surface of a second inorganic solid support to a second surface of the organic solid support via a second bonding layer, so as to form the flowcell. The formed flowcell includes a plurality of channels defined by the surface of the first inorganic solid support, the surface of the second inorganic solid support, and walls of the elongated cutouts.

A method of welding at least two plastic components together is disclosed. The two plastic components are welded together at respective joining surfaces. The method comprises directing at least one infrared (IR) laser beam along the joining surfaces of the at least two plastic components. The IR laser beam heats the joining surfaces of the at least two plastic components to a welding temperature. The method also includes clamping the at least two plastic components together at the joining surfaces to create a weld.

A multi-phasic polymer blend for energy activated edge banding adhesion to a substrate is described. While the blend may be used for adhering edge banding to straight substrates, the blend is preferred for adhering edge banding to contoured substrates. The outer, hard, structural layer of the edge banding is formed from a polypropylene component. The polypropylene component at least includes polypropylene and an optional energy adsorber. The inner adhesion layer of the edge banding is formed from a multi-phasic polymer blend that bonds the outer layer of the edge banding to the substrate. The multi-phasic polymer blend at least includes a polyamide component, a polyolefin component, and a modified polypropylene component. Both the outer and inner layers forming the edge banding may be tinted to conform or contrast with the color of the finished substrate.

Imprinted substrates are often used to produce miniaturized devices for use in electrical, optic and biochemical applications. Imprinting techniques, such as nanoimprinting lithography, may leave residues in the surface of substrates that affect bonding and decrease the quality of the produced devices. An imprinted substrate with residue-free region, or regions with a reduced amount of residue for improved bonding quality is introduced. Methods to produce imprinted substrates without residues from the imprinting process are also introduced. Methods include physical exclusion methods, selective etching methods and energy application methods. These methods may produce residue-free regions in the surface of the substrate that can be used to produce higher strength bonding.

The present invention relates to a method of sealing a module (14) in a hearing device housing. The method comprises the steps of preparing the module (14) and the hearing device housing, and applying a sealing material (28) into a space, said space being formed between the module (14) and the hearing device housing.

A lap shear test fixture and method of use to test the performance of the weld interface in welded thermoplastic composite parts such as infrared welded or resistive implant welded or adhesive bonded composite parts. The specimens to be tested are provided from production-ready parts with typical geometry. The test fixture has at least two aligned blocks with at least two lateral support blocks that operably hold the specimen including two welded substrates. The test is performed in compression-mode at a predetermined crosshead speed until the maximum load produced by a universal testing machine makes the weld interface between the two thermoplastic substrates fail in shear mode.
