Abstract: In a cooling system, a variable inline nozzle controls the flow of cooling fluid. The variable inline nozzle includes a composite fibrous tube through which the cooling fluid flows. Upon manipulation of the composite fibrous tube, a diameter of a portion of the composite fibrous tube is adjusted to control the flow of the cooling fluid.

Abstract: A system comprising a container adapted to house an electronic device. The system also comprises a fan adapted to transfer air between different portions of the container and pressure sensing logic adapted to determine a difference between air pressures at the different portions. The system further comprises control logic adapted to adjust a speed of the fan in accordance with the difference.

Abstract: A cooling system cools air that flows through an electronic system to cool heat generating components. The cooling system maintains a temperature of the air near a set point above a condensation point.

Abstract: The present invention includes an integrated circuit that is operable to connect a redundant array of inexpensive disks (RAID) or other peripheral device to a disk controller, such as a small computer system interface (SCSI) controller in a host device. The integrated circuit provides the peripheral device with sole access to the disk controller when operating in a straight mode. In straight mode, the peripheral device may communicate with the disk controller through a PCI bus to perform operations, such as retrieving or writing data to the peripheral device. Also, when in straight mode, other controllers, including the host's CPU, may be prevented from using the disk controller to avoid data collisions, data loss and possible system failure. The integrated circuit may also function in standard mode, such that other controllers connected to the host may access the disk controller.

Abstract: A method and apparatus for assigning interrupts to devices on a PCI bus in a computer system in which a plurality of address lines are channeled through a multiplexer to a PCI device on the PCI bus. The multiplexer enables the user to dynamically select which address line is routed to the IDSEL pin on the PCI device. According to the PCI specification, the address line connected to the IDSEL pin determines the Device ID for that PCI device. In turn, the Device ID establishes which of the four available interrupt INT# lines are assigned to that PCI device. Thus, the interrupt INT# line assignments can be dynamically controlled. Where desired, the user can force two PCI devices to share an interrupt line, or the user can force the devices to use separate interrupts.

Abstract: An interrupt steering architecture that enables an intelligent peripheral device to process interrupts from PCI devices associated with a PCI bus is disclosed. The interrupt steering architecture enables the PCI interrupt signals to be steered to either a host CPU or to an intelligent peripheral device. The interrupt steering architecture is wholly compliant with the PCI bus specification and does not utilize additional sideband signals. The interrupt steering architecture is under user control and can be set by the user at system initialization or reset.
