Abstract: An electronic device may include one or more sensors that capture sensor data for a physical environment around the electronic device. The sensor data may be used to determine a scene understanding data set for an extended reality environment including the electronic device. The scene understanding data set may include information such as spatial information, information regarding physical objects in the extended reality environment, and information regarding virtual objects in the extended reality environment. When providing scene understanding data to one or more applications running on the electronic device, spatial and/or temporal restrictions may be applied to the scene understanding data set. Scene understanding data that is associated with locations within a boundary and that is associated with times after a cutoff time may be provided to an application.

Abstract: An electric motor (20) has a stator (30) and a rotor (26). The latter is equipped with a cup-like rotor part (56) and with a ring magnet (60) adhesively bonded therein, which magnet has an outer circumference (61) on which are provided elevations (84) and depressions (86) that extend at least partly in the longitudinal direction of the ring magnet (60).
