Abstract

a. Procédé de détection d'une personne ensevelie ou emmurée, par émission d'ondes électromagnétiques entre cette personne et des sauveteurs situés à l'extérieur. b. On équipe la ou les personne(s) courant un tel risque, d'une ou plusieurs cavité(s) résonnante(s) qui peuvent être fixées ou intégrées sur un élément, tel qu'un revêtement, susceptible d'être porté par une telle personne, puis en cas d'ensevelissement de cette personne dans une avalanche de neige, un éboulement ou similaire, on procède à sa détection en dirigeant successivement vers chacun des emplacements présumes de cette personne, un faisceau d'ondes électromagnétiques aptes à faire entrer en résonance la cavité résonnante dont est équipée cette personne du fait que les ondes émanant de l'appareil émetteur se trouvent dirigées dans la direction de cette cavité.
