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.
摘要:
A portable diagnostic apparatus is brought proximal to a device to be diagnosed. While the device to be diagnosed is operating, a radiofrequency interference signal emitted by the device is received at the portable apparatus and a data representation of it is stored. The data representation is submitted for matching to a diagnostic signal pattern stored in a database of predetermined signal patterns. From the matching is identified and output an indication of a fault in the device to be diagnosed. In one embodiment the submitting is to the database stored in the portable apparatus itself, and in another embodiment the submitting is outputting (data cable, wireless link) the stored data representation to a diagnostic computer such as a personal computer, a peer device, or a remote diagnostic center. The RF interference signal may be one stream and the portable apparatus receives at least a second stream and both streams are used for the matching.

摘要:
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.
