  • Patent number: 8191343
    Abstract: Apparatus and methods for cooling controller assemblies for electric utility vehicles are disclosed. Auxiliary implements powered by electric motors onboard a utility vehicle create airflow that is captured and directed to provide increased ambient airflow across heat sinks used to dissipate heat from heat generating components. Airflow across heated surfaces is further created by vehicle movement and vacuum pressure. Fins and other heat dissipating architecture are employed. Features of the cooling systems enable increased controller assembly functionality and/or decreased controller assembly package size.

  • Patent number: 7908493
    Abstract: A mechanism is provided for unified management of power, performance, and thermals in computer systems. This mechanism incorporates elements to effectively address all aspects of managing computing systems in an integrated manner, instead of independently. The mechanism employs an infrastructure for real-time measurements feedback, an infrastructure for regulating system activity, component operating levels, and environmental control, a dedicated control structure for guaranteed response/preemptive action, and interaction and integration components. The mechanism provides interfaces for user-level interaction. The mechanism also employs methods to address power/thermal concerns at multiple timescales. In addition, the mechanism improves efficiency by adopting an integrated approach, rather than treating different aspects of the power/thermal problem as individual issues to be addressed in a piecemeal fashion.
