Publication number: 20240095645Abstract: A method of generating customizable goal representation is disclosed. A request from a user to view a goal representation is received. A flexible goal ontology is accessed that comprises one or more goal entities, one or more goal relationships between the goal entities, or one or more goal properties, the one or more goal properties including one or more metadata attributes relating to the one or more goal entities. A set of mapping rules is obtained that defines mappings between one or more goals. The set of mapping rules is evaluated to assemble a customized goal representation tailored to the user. The customized goal representation is updated based on a revaluation of the mapping rules affected by changes to the one or more goal entities, the one or more goal relationships, or the one or more properties.Type: ApplicationFiled: September 21, 2023Publication date: March 21, 2024Inventors: Sven Martin Andreas Elfgren, Friedrich I.

Publication number: 20180313290Abstract: A method for ascertaining a gas concentration in a measuring gas with the aid of a gas sensor. In a first operating mode of an internal combustion engine, in which the gas concentration in the measuring gas is known, a plurality of value pairs of a respective gas concentration signal and a pressure signal are detected. Proceeding from these value pairs, a compensation parameter and a scaling factor of the gas sensor are ascertained. Subsequently, in a second operating mode of the internal combustion engine, the ascertainment of a gas concentration to be determined takes place, based on a gas concentration signal measured in the second operating mode of the internal combustion engine, and taking the compensation parameter and the scaling factor of the gas sensor into consideration.Type: ApplicationFiled: October 18, 2016Publication date: November 1, 2018Inventors: Thomas ZEIN, Albrecht SCHMIDT, Martin ELMER
