CA 2166984

A method and apparatus for monitoring and controlling the exposure of a user (3) of a handheld portable communi- cation device (2) to RF emissions from the device antenna (1). The total energy transmitted in a predetermined window of time is continuously monitored by the device (2). Should the accumulated transmitted energy exceed a predetermined threshold, measures are taken by the device (2) to control user exposure to the RF emissions from the device antenna (1).

L'invention concerne une méthode et un appareil de contrôle et de régulation de l'exposition d'un utilisateur (3) d'un dispositif de télécommunication portatif à déplacement manuel (2) aux émissions radioélectriques provenant de l'antenne (1) dudit dispositif. Ce dispositif (2) contrôle en permanence l'énergie totale transmise pendant une période donnée. Si l'énergie transmise accumulée dépasse le seuil fixé, le dispositif (2) procède à des ajustements qui régulent l'exposition de l'utilisateur aux émissions radioélectriques provenant de l'antenne (1).
