Title: Procede et appareil de charge rapide d'accumulateur
Inventor: PETROVIC VLADIMIR
IPC: H02J7/00
Filed: 2001-12-10
Abstract: La présente invention concerne des procédés et un appareil permettant de charger un accumulateur qui présentent des cycles de charge dans lesquels les périodes de charge sont séparées par des intervalles. Ces intervalles peuvent comprendre des périodes de décharge. Les séquences de charge habituelles pour des accumulateurs nickel-hydrure de métal ou nickel-cadmium comprennent des périodes de charge d'une durée de 9 secondes à 11 secondes durant lesquelles un accumulateur est chargé à une vitesse comprise entre 1,9×C et 2,1×C et des intervalles qui comprennent des périodes de décharge d'une durée de 0,9 seconde à 1,1 seconde durant lesquelles l'accumulateur est déchargé à une vitesse comprise entre 0,19×C et 0,21×C. Le schéma charge-repos-décharge-repos est répété jusqu'à ce qu'une tension d'accumulateur spécifiée soit atteinte ou qu'un autre événement déclenche la fin du cycle de charge. Des temps de charge d'environ une demi-heure peuvent être réalisés. Cette invention concerne aussi des procédés de charge d'accumulateurs au plomb dans lesquels des impulsions de charge alternent avec des intervalles durant lesquels l'accumulateur n'est pas en charge. Le courant de charge est progressivement réduit sur un certain nombre de périodes.

Title: Parallel port with direct memory access capabilities
Inventor: JIRGAL JAMES J
IPC: G06F13/42
Filed: 1990-10-17
Abstract: PARALLEL PORT WITH DIRECT MEMORY ACCESS CAPABILITIES     Abstract of the Disclosure The parallel or printer port in a personal computer can receive data from the memory under the control of the direct memory access (DMA) controller, releasing processor resources. The processor enables the parallel port, which then indicates to the DMA controller the desire to transfer data. A state machine in the parallel port, along with associated circuitry, responds to the transfer. of the data to the parallel port and then controls the transfer of the data to the attached device, usually a printer. The state machine causes an interrupt to the processor when the transfer is complete or on receipt of errors from the external device. The state machine also communicates with the DMA controller to repeat the transfer process until the transfer is complete or an error occurs. Various DMA channels and parallel port locations can be used. Direct transfers by the processor are blocked during DMA controller handled transfers.
