Title
(EN) A RESERVE POWER SYSTEM FOR ANY BATTERY OPERATED DEVICE
(FR) SYSTEME DE PUISSANCE DE RESERVE DESTINE A UN QUELCONQUE DISPOSITIF COMMANDE PAR BATTERIE
Abstract
(EN)
A mobile telephone with an emergency call capability protected monitors a battery power supply circuit with an emergency call reserve power detector to determine when the power remaining in the battery power supply circuit has decreased beneath a pre-selected minimum emergency call reserve power level that is greater than the absolute minimum level detected by a monitor and battery depletion detector. A microprocessor operating in accordance with a program stored in an emergency call capability program memory selectively inhibits, subject to override, the making of non-emergency calls and terminates ongoing non-emergency calls when said power detector determines that the power supply circuit has gone beneath said pre-selected minimum emergency call reserve power level.
(FR)
L"invention concerne un téléphone mobile comprenant un système de protection, lequel est doté d"une capacité d"effectuer des appels d"urgence et surveille un circuit d"alimentation en puissance d"une batterie, à l"aide d"un détecteur de puissance de réserve destinée aux appels d"urgence, ce détecteur servant à déterminer si la puissance restante du circuit d"alimentation en puissance de la batterie est tombée en dessous d"un niveau minimal et déterminé de puissance de réserve, ce niveau devant être supérieur au niveau minimal absolu détecté par un détecteur de moniteur et d"épuisement de batterie. Un microprocesseur, fonctionnant selon un programme conservé dans une mémoire de programme à capacité d"effectuer des appels d"urgence, inhibe de manière sélective, en vue de l"établissement d"une priorité, les appels non urgents et termine les appels non urgents en cours lorsque ledit détecteur détermine que le circuit d"alimentation de puissance est tombé en dessous du niveau minimal déterminé de puissance de réserve, servant à l"établissement d"appels d"urgence.
