Patent number: 11972272Abstract: An application server provides an application to client devices. Users of the client devices interact with the application to perform a business process. Data regarding user interactions with the application is transmitted from the client devices to the application server. Based on an analysis of the received data, a bot generation server generates a bot to automate a process step. The bot generation server provides a heatmap user interface (UI) that provides information regarding the process steps. Using the heatmap UI, the administrator selects a process step for automation. In response to the selection, the hot generation server identifies, based on the observed behavior, relationships between input fields, typical values for input fields, typical order of data entry into input fields, or any suitable combination thereof. Based on the identified patterns, the hot generation server generates a bot to automate some or all of the process step.Type: GrantFiled: March 9, 2021Date of Patent: April 30, 2024Assignee: SAP SEInventors: Gregor Berg, Andre Niklas Wenz, Bernhard Hoeppner, Thomas Bodner, Olga Cherepanova, Lasse Steffen, Jan Siebert, David Hennemann, Pascal Schulze, Konstantin Dobler, Kris-Fillip Kahl, Paul Udo Beneke, Philipp Bernhard Hoberg

Publication number: 20240035959Abstract: The present invention relates to a spectrometer comprising a plurality of arrays of quantum dots, the arrays being arranged such that primary light emitted by a light source is incident thereon and excites the quantum dots such that the quantum dots emit secondary light such that the secondary light can be incident on a sample, the secondary light having a different spectral distribution to the primary light, at least one detector configured to receive the secondary light reflected or transmitted by the sample, and an evaluation device configured to determine spectral information of the secondary light received by the at least one detector. The invention also relates to a method for producing such a spectrometer.Type: ApplicationFiled: November 9, 2021Publication date: February 1, 2024Applicant: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG E.V.Inventors: Hendrik SCHLICKE, Jan-Steffen NIEHAUS
