Abstract: An electronic device includes a sensor system and is configured to perform a control method to reduce the power consumption during transportation, for example by aircraft. According to the control method, the electronic device evaluates sensor data from the sensor system for detection of a first condition that indicates that a specific mode of transport of the electronic device has begun; switches the electronic device from a first state to the second state upon detection of the first condition; obtains a predicted time to arrival at a destination; performs a status check at a selected time point in relation to the predicted time of arrival, for detection of an arrival of the electronic device at the destination; and switches the electronic device from the second state to the first state upon detection of the arrival.

Abstract: A wireless device includes first and second transceivers for wireless communication and is operable to switch between first and second states, with the second state at least partly prohibiting communication by the first transceiver. The wireless device is configured to perform a control method which involves sharing of state data among wireless devices. According to the method, the wireless device receives, by the second transceiver, a state indicator and confidence data from one or more other wireless devices. The state indicator indicates a current state of the respective other wireless device, and the confidence data is indicative of a confidence of the current state. The control method sets the wireless device in the first or second state based on the state indicator and the confidence data.

Abstract: 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.

Abstract: A wireless device includes a communication system for cellular communication and is configured to perform a control method to improve the ability of the wireless device to connect to a cellular network after air transportation. According to the control method, the wireless device determines an elapsed time since entry into an airborne state, identifies at least one destination by evaluating the elapsed time in relation to flight data that associates destinations with aircraft flight durations, and determines a respective configuration setting, which is associated with the at least one destination, to be applied by the communication system to establish a wireless connection to a cellular network.
