Publication number: 20230222329Abstract: A method evaluates a data-based sensor model for determining a change-point time in a sensor signal time series. The method includes providing an evaluation signal time series within an evaluation time window of a sensor signal time series, and determining sensor signal extracts from the evaluation signal time series. The sensor signal extracts are (i) time-shifted with respect to one another, or (ii) respectively offset from one another by a number of sensing steps. The sensor signal extracts are shorter in length than the evaluation signal time series. The method further includes determining one or more frequency contributions from the sensor signal extracts using a fast Fourier transform (“FFT”) or a Goertzel algorithm, and evaluating the one or more frequency contributions in a trained data-based sensor model in order to determine a change-point time within the evaluation time window.Type: ApplicationFiled: January 12, 2023Publication date: July 13, 2023Inventors: Konrad Groh, Christian Fleck, Matthias Woehrle

Publication number: 20220042960Abstract: A method utilizing a digital twin instance in relation to food to query current/future properties thereof. A digital twin instance representing the food is generated from a digital twin template. The digital twin instance has assigned thereto, for a first target variable describing a food property, a mathematical model with a model parameter and an environmental parameter. The digital twin instance has a probability distribution for the model parameter of the first target variable. In the course of the handling of the food until it reaches a shop and/or at the shop, a measurement of the parameter is made, the values thereof being stored and assigned to the twin instance. The mathematical model of the first target variable, the probability distribution of the model parameter and the values of the environmental parameter are used to ascertain a probability distribution with respect to the target variable.Type: ApplicationFiled: August 4, 2021Publication date: February 10, 2022Inventors: Matthias BRUNNER, Christian Fleck
