Abstract: A lighting device for a motor vehicle includes a lighting component having one or more light sources and one or more transparent facet bodies, each of which bodies has a surface consisting of a plurality of planar first facets. Light originating from the one or more light sources is radiated into the one or more transparent facet bodies as first luminous radiation. The first luminous radiation is at least partially refracted on first facets of the one or more transparent facet bodies and subsequently exits the lighting device as second luminous radiation in order to produce light distribution. One or more translucent optical components are located in the lighting device between the lighting component and the one or more transparent facet bodies.

Abstract: In an approach for automatically detecting whether an output of a detection and segmentation algorithm is of an acceptable quality, a processor receives an image. A processor applies a detection stage of a detection and segmentation algorithm to the image. A processor computes a set of features from a detection score map output by the detection stage of the detection and segmentation algorithm by analyzing the detection score map at more than one different operating points. A processor inputs the set of features into a classifier that predicts whether a final output of the detection and segmentation algorithm will be of an acceptable quality, wherein the acceptable quality is defined based on whether a detection precision threshold has been reached. A processor receives an output of the classifier.

In an embodiment, such a method comprises adding an acid to an ozonized reaction mixture, the ozonized reaction mixture comprising ozonized lignin having a backbone, and aromatic monomers cleaved from a lignin, under conditions to react the cleaved aromatic monomers with the backbone of the ozonized lignin to form a lignin prepolymer. The methods may further comprise using the lignin prepolymer to form a lignin resin.

Abstract: Image editing on a wearable device includes a system which obtains sensor data via the wearable device. The sensor data includes a representation of hand movement, head movement or voice command associated with a user. The system executes an application for editing an image based on the obtained sensor data. The system provides for display a list of image adjustment types associated with the application. The system selects an image adjustment type based on one or more of the hand movement, the head movement or the voice command. The system provides for display a prompt having options to adjust a property of the selected image adjustment type. The system selects one of the options included in the prompt. The system modifies an image based on the selected option. The system then provides the modified image for storage in a data structure of a memory unit in the wearable device.

Abstract: An illumination apparatus for a motor vehicle includes a lighting device having one or more light sources, a reflector arrangement having one or more scatter reflectors, and one or more transparent bodies each having a surface made of a plurality of flat facets. The illumination apparatus is designed such that light generated by the light source(s) of the lighting device is scattered at the scatter reflector(s) of the reflector arrangement, as a result of which scattered light is created, which is refracted at least partially on facets of the transparent body or bodies and then exits the illumination apparatus in order to generate a light distribution.

Abstract: A lighting device for a motor vehicle includes a lighting apparatus which has one or more light sources and one or more transparent bodies which each have a surface made of a plurality of flat facets. The lighting device is configured such that light which comes from a light source at least in part passes through a transparent body and is refracted at facets of the transparent body. The light which passes through the transparent body at least in part exits from the lighting device in order to create a light distribution. An associated transparent body is a molded component having one or more recesses which are integrally molded in the molded component, the molded component being clamped in the lighting device by the engagement of one or more projections into the one or more recesses.

Abstract: Methods for producing acetaldehyde from ethanol are provided. In embodiments, such a method comprises (a) exposing ethanol and furfural to a biocatalyst comprising yeast alcohol dehydrogenase 1, yeast alcohol dehydrogenase 2, and yeast alcohol dehydrogenase 3, and a biocatalyst cofactor under conditions that oxidize the ethanol to acetaldehyde and reduce the furfural to furfuryl alcohol to provide a product mixture comprising the acetaldehyde and the furfuryl alcohol; and (b) recovering the acetaldehyde from the product mixture as it is being produced in step (a).

Abstract: Integrated processes are disclosed for the catalytic conversion of carbohydrate to ethylene glycol and/or propylene glycol using a homogeneous, tungsten-containing retro-aldol catalyst. In these processes, the carbohydrate is subjected to retro-aldol conversion and hydrogenation to provide a reaction product containing ethylene glycol and/or propylene glycol, other reaction process including organic acids, itols and tungsten species. Ethylene glycol and propylene glycol are separated from the reaction product for purification, and at least a portion of the remaining fraction is subjected to ion exclusion chromatography to provide an eluant containing tungsten species and a subsequent eluant containing organic acids and a substantially reduced concentration of tungsten species. At least a portion of the eluant containing tungsten species can be recycled for reuse directly or with intervening unit operations to enhance the catalytic activity of the tungsten species.

Abstract: A lesion detection and classification artificial intelligence (AI) pipeline comprising a plurality of trained machine learning (ML) computer models is provided. First ML model(s) process an input volume of medical images (VOI) to determine whether VOI depicts a predetermined amount of an anatomical structure. The AI pipeline determines whether criteria, such as a predetermined amount of an anatomical structure of interest being depicted in the input volume, are satisfied by output of the first ML model(s). If so, lesion processing operations are performed including: second ML model(s) processing the VOI to detect lesions which correspond to the anatomical structure of interest; third ML model(s) performing lesion segmentation and combining of lesion contours associated with a same lesion; and fourth ML models processing the listing of lesions to classify the lesions. The AI pipeline outputs the listing of lesions and the classifications for downstream computing system processing.

Abstract: A false positive removal engine is provided. The false positive removal engine receives detected objects in one or more images. A machine learning classifier computer model, configured with first operational parameters to implement a first operating point, processes the received input to classify each detected object as being a true positive or a false positive to generate a first set of object classifications. If the first set is empty, the false positive removal engine outputs the first set as a filtered list of objects; otherwise the ML classifier computer model is configured with second operational parameters to implement a second operating point, different from the first operating point, which then processes the received input to classify each detected object and generate a second set of objects classified as true positive, which is output by the false positive removal engine as the filtered list of objects.
