  • Patent number: 7596461
    Abstract: A system for measuring air quality in wireless networks. In particular implementations, a method includes computing an interference severity level for a plurality of interference sources detected at an access point; aggregating one or more of the computed interference severity levels relative to the access point; and computing an air quality metric for the access point, wherein the air quality metric based at least in part on an equation: 1—aggregated interference severity level.
    Type: Grant

  • Publication number: 20070095504
    Abstract: A radiator may have a first cooler that may be connected to a lower end portion of the radiator. The first cooler may comprise a bottom compartment. The bottom compartment may have a front wall, a rear wall, first and second spaced apart side walls, a bottom wall and a lower portion. A radiator outlet port member may be connected to the lower portion. A cooling core may be positioned in the bottom compartment. A baffle may be connected to the bottom compartment and positioned above the cooling core. An opening may be disposed in the baffle at a location closer to a one of the first and second side walls than another of said first and second walls.

  • Publication number: 20070089874
    Abstract: A cooling system for a work machine may comprise a reservoir configured to hold a supply of fluid, a source of pressurized fluid and a valve configured to receive the pressurized fluid from the source of pressurized fluid. A first working unit and a second working unit may be connected to the valve in parallel. One of The first and second working units may be adapted to receive pressurized fluid on a priority basis from the valve. The first and second working units may be fluidly connected to the reservoir by a circulation conduit and may be connected to a first heat exchanger by a bypass conduit. The bypass conduit may be configured to pass only a portion of the fluid flow to be passed from the first and second working units to the first heat exchanger. The first heat exchanger may be fluidly connected to the reservoir and may be adapted to pass the portion of the fluid flow to the reservoir.

  • Patent number: 7181401
    Abstract: Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. A computer or other processor includes a local area network controller, which provides routing and hub(s) for one or more packet networks. The computer also is coupled to a buffer/framer, which serves to frame/deframe data to/from the computer from TDM bus.

  • Publication number: 20060085412
    Abstract: A system for managing content and work items in a plurality of disparate content repositories and workflow systems. The first module organizes content, content organizing structures, work items, and/or work organizing structures into virtual repositories. The second module provides access to workflow in disparate workflow systems having a plurality of proprietary program interfaces. The third module creates rich relationships between two or more pieces of content, content organizing structures, work items and/or work organizing structures that exist in a plurality of content repositories, workflow systems and/or other external information sources.
