Application ramp rate control in large installations
To eliminate the adverse effects of power swings in a large scale computing system during the life cycle of an application or job, control of several operating characteristics for the collective group of processors is provided. By providing certain levels of coordination for the many processors utilized in large scale computing systems, significant and abrupt changes in power needs can be avoided. In certain circumstances, this may involve limiting the transition between several C-States of the processors involved and the overall power transitions for a large scale system are not detrimental and do not create issues for the data center or local power utility. Some cases will require stepped transitions between C-States, while other cases will include both stepped and modulated transitions. Other cases will incorporate random wait times at the various transitions in order to spread the power consumption involved. In yet further circumstances the C-States can be pinned to a specific setting, thus avoiding transitions caused by C-State transitions. To deal with further issues, the processor P-States can also be overridden. |

Persistent power over ethernet
Embodiments described herein improve availability of a power plane in a network device by using a PoE manager that is separate from an operating system in the network device. For example, when the operating system (or a PoE application executing in the operating system) becomes unavailable, either because of failure or system upgrade, the PoE manager continues managing a power plane in the network device such that connected PDs continue to receive DC power. Stated differently, by using a PoE manager that is separate from the operating system, there is no fate sharing between the PoE manager and the operating system. If the operating system is unavailable, the PoE manager continues to provide the same power allotment to the PDs. As such, updates and failures which previously made the power plane unavailable no longer affect the power supplied to the PDs. |

If the current airflow does not meet an airflow requirement, the network device can incrementally increase the temperature thresholds of the identified components, provide the increased thresholds to its fan control algorithm, and subsequently re-check the current airflow. These steps can repeat until the current airflow meets the airflow requirement. |

Measuring formation porosity and permeability
Values for porosity and permeability of core samples in a borehole are estimated by generating radial waves with an acoustic source in fluid around the core sample, and measuring pressure in the fluid. Moreover, the acoustic source operates at frequency close to a resonant frequency of the core sample. After the acoustic source no longer operates at the resonant frequency, pressure in the fluid attenuates over time. The pressure attenuation is recorded by the pressure measurements, along with the pressure in the fluid at the first harmonic (spectral component). The pressure attenuation and spectral component each are dependent on porosity and permeability of the core sample. Thus values for the porosity and permeability are determined based on the arithmetic relationships between pressure attenuation and the spectral component and porosity and permeability. |

Trailer cleanout portal assembly
A trailer cleanout portal assembly includes an inner bracket attached to an inner surface of a trailer perimeter wall. The inner bracket includes a first central aperture extending therethrough that is alignable with a wall aperture in the perimeter wall. A cover bracket is attached to the inner bracket with the perimeter wall positioned between the inner and cover brackets. The cover bracket has an access aperture extending therethrough that is aligned with the first central aperture. A panel positioned between the inner bracket and the cover bracket is vertically movable to open or close the access aperture. An open space is defined extending from a lower edge of the panel and between the cover bracket and the inner bracket such that material falling between the inner and cover brackets freely falls downwardly from the assembly. |

Biaxial hinge
A biaxial hinge which can be downsized. The biaxial hinge includes a first main body, an intermediate body coupled to the first main body so that the intermediate body can rotate around a first shaft and a second main body coupled to the intermediate body so that the second main body can rotate around a second shaft which is parallel with the first shaft. Two laminated first friction plates are engaged with the first shaft. Two laminated second friction plates are engaged with the second shaft. The first main body supports the first shaft so that the first shaft cannot rotate. The second main body supports the second shaft so that the second shaft cannot rotate. The first friction plates and the second friction plates are contained in the intermediate body so that the first friction plates and the second friction plates cannot rotate. |

Door closure
Disclosed is a closure for a door of a shipping container. The closure includes a housing, an outside handle pivotally mounted relative to the housing, an inside handle pivotally mounted relative to the housing, and a catch connected to the inside handle. The closure is configured so that movement of the inside handle between a first position and a second position causes corresponding movement of the catch. A locking mechanism can releasably fix the inside handle relative to the outside handle, such that when in a locked position rotation of the outside handle causes corresponding rotation of the inside handle and when in an unlocked position the inside handle can be rotated independently of the outside handle. |
