Abstract: A process for producing a biocompatible three-dimensional article, the process comprising the steps of providing in an elastin derivative provision step a water-soluble elastin derivative, producing in a hydrogel production step a hydrogel for 3D bioprinting comprising said water-soluble elastin derivative, and 3D bioprinting in a bioprinting step the biocompatible three-dimensional article by extrusion of said hydrogel.

Abstract: The present invention relates to a process for the surface treatment of poly(aryl ether ketone)s (PAEKs) comprising the following steps: Providing an article comprising one or more poly(aryl ether ketone)s (PAEKs); contacting at least one portion of the surface of the article containing one or more poly(aryl ether ketone)s (PAEKs) with an aldehyde, wherein the aldehyde reacts with the poly(aryl ether ketone)(s) (PAEKs) on the at least one portion of the surface of the article to form a hydroxyalkyl and/or hydroxyaryl group, a process for functionalizing surface-treated poly(aryl ether ketone)s (PAEKs) comprising the steps of: a) Treating at least one portion of the surface of an article containing one or more poly(aryl ether ketone)s (PAEKs) with the surface treatment process for poly(aryl ether ketone)s (PAEKs) described herein; b) Coating the treated at least one portion of the surface of the article with a composition comprising a chemical compound having chemical groups capable of forming a covale

Abstract: In order to determine an easily perceived display image for a driver assistance system, in particular a distance-measuring system or a parking assistant, a method makes use of the determination of Bezier curves on the basis of measured distance values on various measuring lines. Wherein different variants for the selection of the reference points and the curve edge points are available for the modeling and parameterization of the Bezier curves taking into account the respective current situation. It is also possible for object positions not to be taken into account under certain conditions in order to obtain smooth illustrative curves.
