Title (EN) ENHANCED PORTABLE BATTERY POWERED ELECTRICAL APPLIANCE
(FR) APPAREIL ÉLECTRIQUE PORTATIF AMÉLIORÉ ALIMENTÉ PAR BATTERIES
Abstract:
(EN) A portable battery powered appliance such as a flashlight accepts at least first and second batteries (1021, 1022). The appliance also includes an electrical load (110) such as a light source. A first circuit (1041) such as a DC to DC converter receives power from the first battery (1021) and supplies power to the load (110). A second circuit (1042) such as a DC to DC converter receives power from the second battery (1022) and supplies electrical power to the load (110). In one embodiment, the appliance accepts batteries (102) having multiple physical sizes.
(FR) L'invention concerne un appareil portatif alimenté par batteries, tel qu'une lampe de poche qui accepte au moins des première et seconde batteries (1021, 1022). L'appareil inclut également une charge électrique (110) telle qu'une source lumineuse. Un premier circuit (1041), tel qu'un convertisseur continu - continu, reçoit de l'énergie en provenance de la première batterie (1021) et applique l'énergie à la charge (110). Un second circuit (1042), tel qu'un convertisseur continu - continu, reçoit de l'énergie en provenance de la seconde batterie (1022) et applique l'énergie électrique à la charge (110). Dans un mode de réalisation, l'appareil accepte des batteries (102) présentant des tailles physiques multiples.
