  • Patent number: 7975286
    Abstract: A method and apparatus for evaluating one or more assets for compliance to at least one network security policy are disclosed. For example, the method receives a request for evaluating at least one asset for compliance to at least one security policy. The method then performs an evaluation of compliance on the at least one asset to determine compliance of the at least one asset to the at least one security policy. The method then records a result of the evaluation of compliance into a database. Finally, the method tracks the at least one asset that has been deemed to be non-compliant to the at least one security policy over a period of time.

  • Patent number: 6305406
    Abstract: A spray hood device for containing a fluid spray leak in a fluid-based cooling system. A cover member surrounds a given component subject to a fluid spray leak, containing fluid sprays, preventing the fluid sprays from reaching equipment therebelow and minimizing fluid leakage damage.
    Type: Grant

  • Patent number: 6161612
    Abstract: A cooling system employing redundant system components is disclosed. The system includes multiple sets of heat: exchanger units, with each set being in fluid communication with a separate, independently operated fluid pump unit. The heat exchanger units are arranged in at least one row of heat exchanger units. The two sets of heat exchanger units are evenly interspersed with each other along the row of heat exchanger units so that a substantially uniform distribution of cooled air is provided in the event one fluid pump unit fails.

  • Patent number: 6034873
    Abstract: A cooling system and method employing separation chutes and baffles is disclosed. The separation chutes separate the cooled air descending from a heat exchanger positioned above heat-generating equipment in an equipment room from heated air ascending from the heat-generating equipment. Separation of the airflows reduces turbulence and increases cooling efficiencies. The separation chutes are made of a variety of materials, both rigid and flexible, for a variety of applications.

  • Patent number: 5975114
    Abstract: A system, method and apparatus for detecting a fluid leak in a fluid based cooling system and purging the fluid therein under various conditions. The system, method and apparatus detect fluid levels in the cooling system, fluid pressure in the cooling system and fluid spraying and dripping from the cooling system. Upon an affirmative determination of low fluid levels, low fluid pressure or fluid spraying and dripping from one or more locations in the cooling system, the device automatically purges the fluid from the cooling system. Accordingly, in an overhead fluid-based cooling system, any damage to objects below from having fluid leaked thereon is minimized.
