A portable electronic device is controlled, for example to selectively activate a flight mode, based on first event data and/or second event data. The first event data is generated by operating a first model for detection of airplane flight events, AFEs, on first sensing data representing ambient pressure. The second event data is generated by operating a second model for detection of AFEs on second sensing data representing own motion or ambient sound. A control method in the portable electronic device generates training data comprising groups of time-aligned data samples from the first event data and the second sensing data, generates an updated second model by use of the training data, and replaces the second model by the updated second model. The control method facilitates adaptation of the portable electronic device to detect airplane flight events in new environments and enables improved robustness when detecting AFEs.

Operating a portable electronic device to detect airplane flight events

A method includes obtaining a benchmark of an accuracy of at least one of a direct positioning technique or an indirect positioning technique for positioning of a mobile device. The method also includes, depending on the benchmark, selecting between positioning of the mobile device using the direct positioning technique and the indirect positioning technique.

Selecting a positioning technique based on the accuracy

A method of determining the location of the first object () may include receiving signals at a second object () from a plurality of measurement points () on the first object (), estimating locations of the plurality of measurement points () on the first object (), determining an estimate of a location of the first object (), determining a first measurement of an orientation of the first object () based on the estimating of the locations of the plurality of measurement points () on the first object (), and determining a second measurement of the orientation of the first object () based on measurements by an orientation sensor () on the first object (). The method may include estimating an error of the estimate of the location of the first object () based on a difference between the first and second orientation measurements and adjusting a movement of the second object () based on the estimated error.
