Dennis John Hansen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8755165
    Abstract: The presently disclosed technology provides a responsive ion beam source power supply system capable of handling fault events without relying on conventional protection circuitry (e.g., fuses and breakers) so that physical power supply hardware intervention by a user is minimized for typical fault conditions and the ion beam source power supply system may recover automatically after experiencing a fault condition. The presently disclosed technology further discloses an ion beam source power supply system capable of detecting and diagnosing fault states, autonomously implementing command decisions to preserve or protect the function of other ion source modules or sub-systems, and/or mitigating or recovering from the disruptive fault event and returning the ion beam source system to desired user settings.
    Type: Grant

  • Patent number: 8197124
    Abstract: A rack mount assembly measurement tool, for determining physical values including air flow and heat loads, includes a front assembly and a rear duct assembly that are non-intrusively and releasably mounted on the front and rear of such rack mount enclosure. Physical values are sensed at multiple vertical locations to enable a determination of overall and localized heat loads within the enclosure. Front sensor values are collected and wirelessly transmitted from the front assembly to a receiver/processor supported on the rear duct, which generates computed values that are displayed in addition to the sensed values.

  • Patent number: 7660116
    Abstract: Rack assemblies and methods for cooling one or more rack-based computer systems, as well as data center configurations that utilize the rack assembly. The rack assembly comprises a rack providing support for multiple columns of heat-generating electronic devices and device fans for moving air from an air inlet side of the rack through the devices and through an air outlet side of the rack. The rack assembly also comprises a unitary door having a support frame spanning the air outlet side of the rack and hingedly coupling the door to a rear vertical edge of the rack. The door includes an air-to-liquid heat exchanger panel spanning an air outlet passage inside the support frame so that substantially all of the air passing through the air outlet must pass through the heat exchanger panel. The air outlet passage has a cross-sectional area that is substantially equal to or greater than the cross-sectional area of the multiple columns of heat-generating devices.
