Abstract: A handheld computer which contains an LCD display having a digitizing surface to allow pen input. Internal storage takes several forms, such as a large flash ROM area, battery-backed up RAM and an optional hard disk drive. Several alternative communication paths are available, such as the previously mentioned modem, a parallel printer port, a conventional serial port, a cradle assembly connected to the host computer, and various wireless short distance techniques such as radio frequency or infrared transmission. The computer can readily communicate with other sources, particularly to a host desktop computer, to allow automated synchronization of information between the host and the handheld system. Preferably the remote synchronization is performed at several user selectable levels. When the handheld computer is in a cradle and actively connected to the host computer, automatic capture of updated data in the host computer is performed. Several synchronization tehcniqques are utilized to keep track of different types of files. In addition, while communication is established the handheld computer can enter a remote control mode, allowing the user access to files and applications not included in the handheld computer.

Abstract: A battery charge controller and fuel gauge which accurately monitors the voltage, temperature, and charge and discharge current of a rechargeable battery, and calculates the battery's charge capacity and charge level. Each time the battery is fully discharged, any calculated charge level remaining is divided by two and subtracted from the previously calculated charge capacity. When the battery is fully charged, the charge level is set equal to the charge capacity. During subsequent charge and discharge, the current is converted to a coulomb count and added or subtracted from the charge level to maintain an accurate charge level. Fast charge inefficiency due to temperature is considered by subtracting a temperature proportional factor before the charge level of the battery is updated. The charge level, voltage and temperature are used to determine the optimal fast charge termination point to achieve full charge and prevent temperature abuse and overcharge. A fast charge is applied only if the battery is within proper voltage and temperature ranges. The charge controller includes a microcontroller circuit within the same battery pack as the battery, which is powered by the battery when AC power is unavailable. The microcontroller circuit consumes very little power, measures circuit errors to assure data accuracy, times periods of self-discharge and updates the charge level accordingly. The microcontroller circuit also includes memory to store the battery charge information and a communication port to provide the charge information to a computer system connected to the battery pack.

Abstract: Un contrôleur de charge de batterie et indicateur de niveau de charge contrôle précisément la tension, la température et le courant de charge et de décharge d'une batterie rechargeable et calcule la capacité de charge de la batterie et son niveau de charge. Chaque fois que la batterie est complètement déchargée, tout niveau de charge résiduel calculé est divisé par deux et soustrait de la capacité de charge précédemment calculée. Quand la batterie est pleinement chargée, le niveau de charge est réglé à un niveau égal à sa capacité de charge. Pendant les décharges et recharges ultérieures, le courant est converti en un nombre de Coulomb et ajouté ou déduit par rapport au niveau de charge pour que ce dernier reste à un niveau précis. On tient compte de l'inefficacité de recharge rapide due à la température en soustrayant un facteur de température proportionnel avant rectification du niveau de charge de la batterie. Le niveau de charge, la tension et la température permettent de déterminer le moment optimum de fin de recharge rapide et d'obtenir une recharge complète tout en prévenant les dépassements de température et les excès de charge. La recharge rapide survient uniquement si la batterie se trouve dans les fourchettes de tension et de température appropriées. Le contrôleur de charge comporte un micro-circuit intégré au boîtier de la batterie et alimenté par celle-ci lorsqu'on ne dispose pas du courant alternatif. Ce micro-circuit de contrôle consomme très peu d'energie, mesure les erreurs au niveau des circuits afin d'assurer la précision des données, chronomètre les périodes d'auto-décharge et rétablit le niveau de charge en conséquence. Il comporte aussi une mémoire destinée aux informations de charge de la batterie et un port de communication permettant de transférer ces informations de charge vers un ordinateur connecté à la batterie.
