The invention relates to a method of initiating a wireless transfer of data between two electronic devices. In order to make the initiation particularly user friendly, it is proposed that a concept called 'hugging' is employed. A hugging state between two electronic devices is assumed to be given if a first electronic device and a second electronic device are determined to undergo a specific motion pattern relative to each other while being at least in close vicinity to each other. Only in case such a hugging state is detected at a first device, a data transfer channel is opened for transferring data between the first device and some other device, e.g. the second device. The invention relates equally to a corresponding device and to a software program product with a corresponding software code.

Altimeters correct themselves by analyzing pressure data to identify underlying climatic changes and modify sensed pressures accordingly to provide corrected altitude values. The detected underlying climatic changes are used to provide a barometer function independent of altitude changes. Air pressure measured at a plurality of times is stored to provide historical pressure data. A reference pressure is modified in dependence on historical data to produce a modified reference pressure. An altitude value is obtained from the current air pressure value and the modified reference pressure and stored.

The invention relates to a mobile radio-frequency enabled device. In order to enable a lightning detection by means of such a device, it comprises an electromagnetic interferences detection component detecting electromagnetic interferences in at least one radio-frequency channel, which at least one radio-frequency channel is usable by the mobile radio-frequency enabled device for a communication link. The device further comprises a processing component adapted to determine whether a lightning stroke can be assumed to have occurred in the vicinity of the mobile radio-frequency enabled device due to an electromagnetic interference detected by said electromagnetic interferences detection component. The invention relates equally to a corresponding system, to a corresponding method and to a corresponding software program product.

Detection of lightning

A mobile radio-frequency enabled device that provides a reliable and inexpensive lightning alerting of a user. The device comprises an electromagnetic interferences detection component detecting electromagnetic interferences in radio-frequency signals received by the mobile radio-frequency enabled device for a communication link. The device further comprises a processing component to determine whether a lightning stroke can be assumed to have occurred in the vicinity of the device due to an electromagnetic interference detected by the electromagnetic interferences detection component, and to cause a notification of a user about an assumed lightning stroke via a user interface. The invention relates equally to a system which comprises such a device and a network element of a communication network, to a corresponding method and to a corresponding software program product.
