Abstract

An improved mobile telephone (1) is made. It is improved in the sense that it assesses the SAR, namely the power thermally absorbed by a material representing biological tissues placed against the telephone in conditions of use, and it parametrize its operation according to this rate. Thus, a solution is proposed guaranteeing the user a use of the telephone that is without risk for his health.

Claims

1. A mobile telephone comprising means to know the proximity of a mobile telephone user'"'"'s brain and means to assess a dose of radiation absorption that the mobile telephone might produce in the user'"'"'s biological tissues, in conditions of use, the assessment of the radiation dose taking account of the proximity or non-proximity of the user'"'"'s brain.

2. A telephone according to claim 1, wherein absorption dose is a specific absorption rate (SAR).

3. A telephone according to claim 1, comprising means to parametrize its operation as a function of the result of the assessment.

4. A telephone according to one of the claims 1 to 3, comprising means for the simultaneous execution of a voice communication and a data communication.

5. A telephone according to one of the claims 1 to 4, comprising means for the display, on a screen, of a specific absorption rate (SAR) or a crossing or non-crossing of a limit by this rate.

6. A method for the parameterization of a mobile telephone wherein:

an emitted energy is measured,

the emitted energy measurement is processed to make it representative of a dose received by the user,

this processed measurement is compared with a threshold,

a limitation of activity of the telephone is determined as a function of the result of the comparison.

7. A method according to claim 6, wherein

the energy measured by the telephone during a sliding period is measured.

8. A method according to one of the claims 6 and 7, wherein

the proximity of a user'"'"'s brain with respect to this telephone is measured.

9. A method according to claim 6, wherein

a value of emitted energy is emitted on the basis of instructed values of power emission dictated by a base station.

10. A method according to one of the claims 6 to 9, wherein

a measurement of the SAR is weighted (C) as a function of the proximity of a user'"'"'s brain.
