Polyester polymer compositions are described containing a blend of coloring agents and optionally reinforcing fibers. The polyester polymer, for instance, can be polybutylene terephthalate. The polymer composition is particularly formulated in order to be substantially transparent at specific wavelengths of light. Consequently, the polyester polymer composition is well suited for use in laser transmission welding in which a laser beam passes through the polymer composition and forms a weld on an adjoining surface.

The present invention relates to an additive for laser-markable and/or laser-weldable polymer materials, and in particular to the use of pigments which comprise niobium-doped titanium dioxide as laser absorbing additive in polymer materials, to polymer materials which comprise a laser absorbing additive of this type and to a laser-marked or laser-welded product comprising at least one polymer material and niobium-doped titanium dioxide containing pigments as laser absorbing additive.

Disclosed are a method of fixing an optical fiber and a measuring apparatus using the same, in which the method includes (a) heating a fixing portion where the optical fiber is to be fixed to an object, and (b) forming a concavo-convex structure by melting the heated fixing portion. The optical fiber is fixed to the object by filling an adhesive or filler in a state in which the fixing portion having the concavo-convex structure is disposed in an insertion space formed in the object. The optical fiber and the object can be firmly fixed using the mechanical coupling structure by forming the concavo-convex portion in a part where the optical fiber is to be fixed, and slip can be prevented from occurring between the cladding and the covering jacket.

A method for generating a camera image from which a welding contour can be derived along which an assembly is to be welded in an image processing-supported laser transmission welding method. The transparent component of the assembly is illuminated from a side facing away from the camera. The invention also relates to a device which is suitable to carry out the method and wherein an illumination device has at least one light source, the light source being arranged in a workpiece holder in which the assembly to be welded is received in a receiving area and being directed into the receiving area.

Provided is a connector apparatus including: a circuit board; a connector; and a mold resin portion, wherein the circuit board includes a conductor path, the connector includes a housing with a cylindrical shape and made of a resin, and a terminal projecting outward in an axial direction of the housing from inside the housing, the terminal being configured to connect to the conductor path, the mold resin portion collectively covers the circuit board, the terminal located outside the housing, and a portion of the housing; the housing and the mold resin portion include a welded portion formed by welding together constituent materials of the housing and the mold resin portion, and the welded portion is provided around an entire periphery of the housing and has a difference between a maximum width and a minimum width along a circumferential direction of the housing of 30% or less of the maximum width.

A thermoplastic composite structure is produced by consolidating and forming a composite preform to a desired shape. The preform comprises plies of a high melt temperature thermoplastic prepreg that are tacked together by a low melt temperature thermoplastic adhering the plies together in fixed registration.

A laser-weldable composition and method using the same, said composition comprising at least one amorphous polyamide made from the polycondensation of at least an acyclic aliphatic diamine comprising at least 10 carbon atoms and/or at least an acyclic aliphatic diacid comprising at least 10 carbon atoms, and at least a phthalic acid selected from the group consisting of terephthalic acid and isophthalic acid, at least one flat glass fiber; and at least one organic dye which absorbs radiation at a wavelength from 800 to 1400 nm.

Systems and methods for controlling a pump system for use in negative pressure wound therapy are described herein. In some embodiments, a method for controlling a pump system includes applying a drive signal to a pump assembly of the pump system, the drive signal alternating between a positive amplitude and a negative amplitude and the drive signal having an offset, and sampling a pressure within a fluid flow path configured to connect the pump system to a wound dressing configured to be placed over a wound during one or more time intervals. Each of the one or more time intervals can occur when the drive signal is approximately at an amplitude equal to one or more sampling amplitudes.
