Abstract: A sensor system comprises a LiDAR unit having an emitter for laser light having a wavelength of 900 nm to 1600 nm and a receiver for light over a wavelength range which is between 800 nm and 1600 nm and at least partly below the operating wavelength of the LiDAR sensor and a cover having a substrate layer made of thermoplastic material which is arranged such that IR light emitted by the LiDAR unit and received by the LiDAR unit passes through the cover.

Abstract: The present invention relates to a layer arrangement, having: a foil layer (100) provided with optical information, and a three-dimensionally structured layer (200) having a smooth side (210) and a structured side (220) opposite the smooth side (210), wherein the structured side (220) has at least one face (230) which is not coplanar with the smooth side (210) and faces a previously defined reference location (400), and the structured side (220) has at least one face (235) which is not coplanar with the smooth side (210) and faces away from the previously defined reference location (400). The three-dimensionally structured layer (200) is formed by a thermoplastic polymer which has an optical haze Ty (D65/10°) according to ASTM D1003 of ?10% with a layer thickness of 4 mm. The foil layer (100) provided with optical information is connected to the structured side (220) of the three-dimensionally structured layer (200).

Abstract: A computer-implemented method for optimising an injection moulding process for producing thick-walled components based on a model parameterised on the basis of parameters to be predetermined is provided, wherein a component to be produced is represented in the model with a component geometry, and the method comprises at least the following steps: e) defining a group of parameters as primary characteristics on the basis of a relative influence of the parameters on a predetermined model response, and f) defining parameter values for the primary characteristics as starting values for a subsequent optimisation of the model and of respective tolerance ranges for the primary characteristics, c) optimising the parameter values of the individual primary characteristics with respect to a desired value of the model response in the respective tolerance ranges, proceeding from the starting values from step a), and d) setting the optimised parameter values from step c) as the corresponding starting parameter values on an

Abstract: The invention relates to a process for producing plastic components, in particular optical lenses or optical light-guides, wherein plastic melt is injected via a sprue (3, 4, 6, 8) into a cavity (1) of a moulding tool shaping the component and additional plastic melt is after-pressed into the cavity (1) for the purpose of compensating a volume contraction of the injected plastic melt due to cooling. The process is characterised in that the plastic melt located in the sprue (3, 4, 6, 8) is kept flowable by means of energy introduced in the region of the sprue until such time as the molten core of the plastic component has solidified in the course of the after-pressing of plastic melt for the purpose of compensating the volume contraction due to cooling (holding-pressure). The invention further relates to an apparatus for implementing the process.
