  • Patent number: 10379748
    Abstract: Scheduling memory accesses in a memory system having a multiple ranks of memory, at most r ranks of which may be powered up concurrently, in which r is less than the number of ranks. If fewer than r ranks are powered up, a subset of requested powered down ranks is powered up, such that at r ranks are powered up, the subset of requested powered down ranks to be powered up including the most frequently accessed requested powered down ranks. Then, if fewer than r ranks are powered up, a subset of unrequested powered down ranks is powered up, such that a total of at most r ranks is powered up concurrently, the subset of unrequested powered down ranks to be powered up including the most frequently accessed unrequested powered down ranks.

  • Patent number: 7389839
    Abstract: A hybrid drive for a motor vehicle having a thermal engine for operating with a hydrocarbon containing fuel suitable for generating hydrogen is shown. The hybrid drive includes a fuel storage tank, an energy storage device to store energy generated by the thermal engine and a drive motor whose operating state depends on the energy from the thermal engine and/or the energy storage device. The hybrid drive includes an AC/DC converter for producing and storing energy in the energy storage device prior to starting of a hybrid drive. A hydrogen storage device is operatively connected to a hydrogen-generating unit. The hydrocarbon containing fuel is used and stored for generating hydrogen at least one of prior to starting and operation of the hybrid drive for a motor vehicle. The thermal engine can be operated alternatively on hydrogen generated by the hydrogen-generating unit or hydrogen stored in the hydrogen storage device.

  • Patent number: 6945345
    Abstract: A hybrid electric vehicle having alternate fuel sources is shown. The hybrid vehicle includes an AC/DC converter for storing a direct current voltage in a storage device such as a battery. A fuel converter converts a composition combustible fuel into a combustible fuel preferably hydrogen. The combustible material is stored in a combustible fuel storage device. The charging of a battery and the storage of the combustible fuel occur at prior to the starting of or the operation of the hybrid electric vehicle. A driving system includes a direct current motor and a combustible fuel engine. A control device enables the driving system to be powered by the direct current voltage or the combustible fuel. Preferably the combustible fuel is hydrogen. A hydrogen fuel cell is responsive to hydrogen to produce a direct current voltage for charging a battery or driving the direct current motor.

  • Patent number: 6536547
    Abstract: A hybrid electric vehicle having alternate fuel sources is shown. The hybrid electric vehicle includes an alternating current to direct current converter for producing and storing a direct current voltage in a direct current voltage storage device. A fuel converter receives fuel in a first state and converts the fuel into a combustible material or a combustible fuel in a second state which is stored in a combustible material storage device. A driving system for transporting the hybrid electric vehicle includes a direct current motor operatively connected to the direct current voltage storage device. The direct current motor is responsive to a stored direct current voltage for driving the driving system in response to a first control signal. A combustible material engine is operatively coupled to the driving system and drives the driving system in response to a second control signal.
