Publication number: 20240169668Abstract: A computer-implemented method is provided for creating a three-dimensional virtual model of an environment (2) of a motor vehicle (1). The method includes capturing images of the environment (2); determining a plurality of regions (3; 4; 5; 6; 7; 8; 9) in each of the images and calculating a region entropy for each of the regions (3; 4; 5; 6; 7; 8; 9). The method then proceeds by selecting at least one region (4; 9) that has a higher region entropy than other regions (3; 5; 6; 7; 8); and generating the three-dimensional virtual model by first ascertaining three-dimensional coordinates for the selected at least one region (4; 9) and only thereafter ascertaining three-dimensional coordinates for the unselected regions (3; 5; 6; 7; 8). The three-dimensional virtual model includes the three-dimensional coordinates of all regions (3; 4; 5; 6; 7; 8; 9).Type: ApplicationFiled: November 17, 2023Publication date: May 23, 2024Inventors: Stefan Roos, Robin Schwager, Tim Bruehl, Lukas Ewecker

Publication number: 20240155058Abstract: A method for dynamically adjusting a volume level in an online meeting. The method includes step a. holding an online meeting in which participants can have a conversation with one another. In step b. using an AI algorithm, monitoring and recognizing content of a conversation of the participants in the online meeting and assigning content scores to the content, wherein each participant portion of the participants is assigned a recognized sub-content in the conversation based on the content scores. In step c. using the AI algorithm, recognizing a first intersection of content scores from a plurality of sub-contents, and recognizing a second or more intersections of content scores from other multiple sub-contents. In step d. adjusting volume levels of individual participants, by raising or lowering the volume level of a participant portion for such other participants having one or no intersection with the participant portion.Type: ApplicationFiled: September 26, 2023Publication date: May 9, 2024Applicant: Dr. Ing. h.c.

Publication number: 20230405062Abstract: The invention herein relates generally to enhancing the survival and activity of probiotic Lactobacillus reuteri strains in mammals by pre-conditioning L. reuteri with GOS during cultivation and to a surprisingly high symbiotic effect of such a pre-conditioned probiotic L. reuteri strain when administered together with GOS further added in the composition. The invention therefore comprises methods for cultivating and manufacturing probiotic L. reuteri strains, and preparing products containing such pre-conditioned strains in combination with additional amounts of GOS. In more detail the present invention relates to a probiotic composition comprising a probiotic L. reuteri strain, obtained by a step of growing the bacteria in a medium comprising GOS, and administering the pre-conditioned bacteria together with further GOS in the final product. The inventors have found that such method induces surprisingly high and unexpected symbiotic beneficial effects of the probiotic bacteria in the gastrointestinal tract.Type: ApplicationFiled: March 11, 2022Publication date: December 21, 2023Inventors: Stefan ROOS, Marie Noëlle HORCAJADA, Nicolas BONNET, Magalie SABATIER, Bertrand BOURQUI, Guénolée Eliane Marie PRIOULT, Florac DE BRUYN

Publication number: 20230362468Abstract: An optical sensor system (1) has plural optical lens systems (2a-2n), a single imaging optical sensor (3) and plural light guides (4a-4n) corresponding to the number of optical lens systems (2a-2n). The light guides (4a-4n) extend respectively between the lens systems (2a-2n) and the optical sensor (3). Each of the lens systems (2a-2n) is associated respectively with one of the light guides (4a-4n). A switching apparatus (5) selectively switches between the light guide means (4a-4n).Type: ApplicationFiled: May 4, 2023Publication date: November 9, 2023Inventors: Simon Isele, Stefan Roos, Lukas Ewecker
