An electronic device and method for data-driven assistance for users involved in physical activities is provided. The electronic device receives first sensor data associated with a movement pattern of one or more parts of a body of a user and receives first information associated with a location where the user performs the physical activity. The electronic device determines one or more first indicators which are likely to have affected the user or the performance of the user in the physical activity. Thereafter, the electronic device generates presentation data based on an application of a first machine learning model on the determined one or more first indicators and the received first information. The generated presentation data includes one or more improvement suggestions for the user in relation to the physical activity. The electronic device controls a display device to display the presentation data.

This fluid measuring device is provided with: an irradiation unit that irradiates a fluid with light; a light receiving unit that receives light scattered by the fluid; a detecting unit that detects a backflow of the fluid on the basis of a light reception signal from the light receiving unit; and a calculating unit that calculates, on the basis of the detection result by the detection unit and the light reception signal from the light receiving unit, estimated fluid information indicating the flow rate or flow speed of the fluid. Accordingly, even when a backflow of the fluid temporarily occurs, the flow speed of the fluid can be precisely measured.

A method described and device to rapidly detect the accident-related removal of a mobile user terminal from a holder and to generate corresponding information which characterizes the fall or crash related to the accident. Rotation-rate sensor variables and acceleration variables of the mobile user terminal are acquired. A rotation or twisting of the mobile user terminal is detected in that the currently acquired and/or integrated rotation-rate sensor variables are compared to past values and/or threshold values. A movement of the mobile user terminal is detected on the basis of the currently acquired and/or integrated acceleration variables. A comparison with past values and/or threshold values may optionally also be carried out. The determination of an in particular accident-related crash of the vehicle and/or the fall of the mobile user terminal out of the holder then takes place due to the detected rotation and the detected movement.

A calibration apparatus of an inertial sensor, obtains an angular velocity value from the inertial sensor, derives a distribution of a difference between temporally adjacent angular velocity values concerning a plurality of angular velocity values obtained during a given period, and determines, based on the distribution, whether the inertial sensor is in a motionless state during the given period. Then, if it is determined that the inertial sensor is in the motionless state, the calibration apparatus decides a bias value of the inertial sensor based on the plurality of angular velocity values and corrects the obtained angular velocity value based on the bias value.
