Title: Method for determining state of charge of a battery by measuring its open circuit voltage
Inventor: SINGH HARMOHAN
IPC: G01R31/36
Filed: 2002-02-14
Abstract: A method (Fig. 1) for determining the state of charge (SOC) of a battery by measuring its open circuit voltage (OCV) either with the battery in a fully rested state of chemical and electrical equilibrium or an active state during a period in which the battery settles after charge or discharge is stopped. A  first type algorithm (Fig. 4) is developed to correlate the OCV in a fully rested condition (OCVREST) to the state of charge at which that measurement is taken. A second type algorithm is developed that predicts a final settling OCV  of a battery (OCVPRED), based on the set of parameters of OCV, rate of change of OCV, and battery case temperature, acquired during the settling period of a battery not at rest. To determine the SOC of a battery being tested that is in the fully settled state the measured OCVREST is applied to the first type algorithm (Fig. 4). To determine the SOC of a battery that has not fully settled, the data of the OCV, rate of change of OCV and battery temperature is applied to a second type algorithm to determine OCVPRED and the OCVPRED value is used in the first type algorithm to determine SOC.

Title: Procedes et dispositifs pour estimations de position precises en cas de deterioration marquee de la precision
Inventor: VAYANOS ALKINOOS H
IPC: G01S19/48
Filed: 2002-06-17
Abstract: L'invention concerne des procédés permettant d'améliorer les estimations de position pour un dispositif donné, en cas de détérioration marquée de la précision. Selon une variante, on reçoit initialement des estimations de position pour un certain nombre d'émetteurs (par exemple, satellites et/ou stations de base GPS) et une série de mesures initiales (par exemple, pseudo-distances). On calcule un vecteur de mise à jour pour une estimation de position de dispositif courante. Après la détection d'une non-convergence de cette estimation vers une estimation de position cible, et confirmation, le vecteur de mise à jour est ajusté (par exemple, réduction de valeur numérique selon un facteur d'échelle), ce qui permet d'augmenter la probabilité de convergence vers l'estimation de position cible. Ensuite, l'estimation est mise à jour sur la base du vecteur de mise à jour (éventuellement ajusté). On peut déceler la non-convergence en fonction du nombre d'itérations accomplies sans parvenir à l'estimation cible, et/ou de l'inversion de phase sur deux vecteurs de mise à jour consécutifs. Il est possible d'augmenter le facteur d'échelle à chaque détection d'événement indicateur de non-convergence.
