Lightning Detectors in Nokia Cell Phones
The software should determine the distance of the lightning, when it occurs, and warn the user of approaching strikes.
Le logiciel pourrait déterminer la distance de l'éclair, lorsqu'il se produit, et ainsi avertir l'utilisateur des impacts en approche.
On a jamais pu prévoir quand et ou tomberait la foudre, si nokia l'avait découvert ça se saurait.
Et en plus ça "marcherait" jusqu'à 30 km.
Personnellement la bonne vieille méthode pour connaitre à quel kilomégrage un éclair se trouve, on compte le nombre de secs entre le flash et la déflagration et on multiplie par 0,34.
Si quelques minutes plus tard ce nombre diminue, alors cours dans l'autre sens si tu tiens à ta peau.

Moins connue par contre, notre petite radio portative lors d’une chasse peut nous avertir d’une zone à TRES HAUT risque de foudre imminent et très proche.
...
Cette ionisation produit également un chaos électromagnétique se traduisant par un grésillement soutenu et intense sur la petite radio portative. Ces grésillements sont la preuve que vous vous situez dans la zone d’impacts imminents et que la fuite s’impose immédiatement.
Pour nous chasseur d'orage sa serai le pied....mais mais j'y crois pas trop.
[0004] From the state of the art, many single-purpose lightning detectors are known, but they have some disadvantages from a commercial perspective. Scientific lightning detectors, which are used in meteorology, are very large and their range is hundreds of kilometers.
....
[0006] In addition, there are now existing rather inexpensive low end lightning detectors which are completely portable in size and which do not require a specific orientation. These detectors, however, are extremely susceptible to man-made electromagnetic compatibility (EMC) emissions and thus tend to cause spurious alarms especially in an urban setting or near highways
[0017] It has been found out that lightning detection and ranging feature would be a desired feature e.g. in mobile phones.
[0024] Preferred embodiments of the present invention further include multiple embodiments of modifying an FM receiver to identify and measure lightning strokes.
[0026] The present invention has the benefit that it can provide a portable lightning detector integrated with a mobile telephone. Another aspect of the invention is that hardware changes can be minimized, in the methods by which hardware (HW) changes can be minimized, thus limiting costs and shortening time to market.
[0008] The present invention proceeds from the consideration, that a lightning stroke is a single flash which produces besides a visual signal and a partly audible pressure signal as well a brief but strong electromagnetic pulse extending over a wide variety of wavelengths. Typical electromagnetic pulses caused by a lightning stroke cover the frequencies between 10 Hz and 5 GHz with a peak around 500 Hz, i.e. in the audio frequency range. At a normalized distance of 10 km, the amplitudes of such pulses range from 107 mV/m to 1 mV/m in a bandwidth of 1 kHz. the strongest signal of the electromagnetic pulse is the induced electric field caused by the vertical current in the lightning stroke, and this is the parameter that is most commonly measured in large-scale distance-bearing devices.
[0002] Thunderstorms are a major weather hazard, but are difficult to predict. They can travel at speeds of 20 km/h to 40 km/h, and lightning strokes may occur more than 10 km in front of the rain clouds and equally some distance behind the rain clouds. While a lightning stroke is produced by a cloud or a weather front, many of the most dangerous lightning strokes actually occur when no visible clouds are present above as a warning of a thunderstorm. Thus, a system that warns of possibility harmful thunderstorms, even if only approximately proximately ten minutes before they become visible, can be considered a major safety feature.
il peut procurer une connaissance bonne-à-savoir de tous les jours... hmmm une autre façon de dire pas grand chose[0003] There is a large population that would benefit from such a safety feature. To some persons, it might provide only a nice-to-know everyday knowledge.
To a considerable number of persons, however, storm and lightning originated threats have significant implications in the form of an increased risk, loss of property or even fatal consequences. A lightning alerting system is of particular interest, for instance, for persons spending much time outdoors, and equally for aviators, navigators or the like. A system providing a warning of lightning even when the weather seems to be perfectly calm and clear may enable a person to take suitable safety measures in time, for instance seek shelter etc.
