  • Publication number: 20120317571
    Abstract: A super operating system for a heterogeneous computer system for executing tasks of software that has at least one performance processor, a processor supporting logic, and a hypervisor processor. The super operating system has a performance operating system for the performance processor; a hypervisor operating system for the hypervisor processor and a heterogeneous hypervisor software layer on top of the performance and hypervisor processors and below the performance and hypervisor operating systems. Under the super operating system, the hypervisor processor executes tasks that the hypervisor processor has sufficient processing power to handle and puts the performance processor to a power-conserving state. The hypervisor processor brings the performance processor out of power-conserving state to execute tasks that the hypervisor processor has insufficient processing power to handle. The performance and hypervisor processors simultaneously execute tasks that require combined processing power of all processors.

  • Patent number: 7840819
    Abstract: An automatic switch method and apparatus are used to set the output current of a USB by slowly increasing the output current under monitoring the voltage on the USB. If the USB could normally operate until the output current reaches a threshold value, a higher level is set for the output current, otherwise a lower level is set instead. The process may be performed periodically to dynamically determine the output current for the USB.

  • Publication number: 20070261828
    Abstract: In one embodiment, a baffle assembly is mounted in a washing tower including an inlet, an outlet, a water pump, a blower, and a water tank and includes lower first baffles of U arranged horizontally or in cascade; and higher second baffles of U arranged horizontally or in cascade. The first and second baffles are further arranged in alternating fashion in opposing directions and the first baffles are offset with respect to the second baffles so that incoming water passes a gap between any two adjacent first baffles and leaves through a gap between any two adjacent second baffles by establishing twin cyclones inside space of the first and second baffles. The twin cyclones can increase holdup time of water in the tower and thus increase washing efficiency. The invention also applies to a burning tower by disposing baffle assemblies in at least of one layer fashion.

  • Publication number: 20070039608
    Abstract: The present invention discloses a baffle assembly structure for producing fluid or flame whirls, which is applied to water-washing or chemical-washing washing towers or heat-resisting burning towers. The structure has a diversion area disposed at a position corresponding to an air inlet in the tower for providing a tangential acceleration for the gas entering into the washing tower or the whirl burning tower, and then the gas will enter into a whirl panel composed of the baffle assembly structure for producing whirls. With the water spray and sprinkle, a good whirling effect will be produced, or a good whirl burning effect is produced for the oil-gas ignition of the whirl burning tower. After different shaped baffles are intersected, arranged and disposed flatly to separate the tower body, the throttle baffle and the baffle produce a negative pressure effect for the gas, so as to improve the water solubility or concentrate the water remained in the washing tower for a chemical washing.
