Title (EN) BATTERY TESTER HAVING PRINTED ELECTRONIC COMPONENTS
(FR) TESTEUR DE PILES AVEC COMPOSANTS ELECTRONIQUES IMPRIMES
Abstract:
(EN) A battery tester circuit in one aspect of the present invention comprises a display circuit for a battery comprising a display component for displaying information pertaining to the battery, and a display driver component for receiving power from the battery to drive the display component, wherein at least one of the components is printed on a substrate. In another aspect, a battery label comprises a label substrate for covering an outer portion of a battery, and an electric field-responsive liquid crystal display printed on an outer surface of the label substrate for displaying information pertaining to the battery. Preferably, the display driver component comprises a battery discharge level sensing circuit that continuously senses the discharge level and the display continuously displays the discharge level. The display is preferably an electric field-responsive liquid crystal display comprising either polymer liquid crystal or polymer-dispersed liquid crystal material. The display may be formed of one or more layers of active liquid crystal material. The display driver component is preferably an oscillator circuit that may also be printed on the substrate.
(FR) Dans un aspect de l'invention, un circuit de vérification de piles, constitué d'un circuit d'affichage destiné à une pile, comprend un composant d'affichage, qui affiche les informations concernant la pile, et un composant gestionnaire d'affichage, qui reçoit l'énergie provenant de la pile de façon à commander le composant d'affichage, au moins l'un des composants étant imprimé sur un substrat. Dans un autre aspect, une étiquette collée sur une pile comprend un substrat d'étiquette, qui recouvre une partie extérieure d'une pile, et un afficheur à cristaux liquides sensible aux champs électriques, imprimé sur une surface externe dudit substrat, qui affiche les informations concernant ladite pile. De préférence, le composant gestionnaire d'affichage comprend un circuit de détection du niveau de décharge de la pile, qui détecte en continu le niveau de décharge, et l'afficheur affiche en continu ledit niveau. L'afficheur est de préférence un afficheur à cristaux liquides sensible aux champs électriques, constitué soit d'un cristal liquide polymère, soit d'un matériau cristal liquide dispersé dans un polymère. Il peut comprendre une ou plusieurs couches de matériau cristal liquide actif. Le composant gestionnaire d'affichage est de préférence un circuit oscillateur, qui peut également être imprimé sur le substrat.
