20120173904 | METHOD, APPARATUS, AND SYSTEM FOR ENERGY EFFICIENCY ANDENERGY CONSERVATION INCLUDING DETERMINING AN OPTIMALPOWER STATE OF THE APPARATUS BASED ON RESIDENCY TIME OFNON-CORE DOMAINS IN A POWER SAVING STATE - A processor may determine the actual residency time of a non-core domain residing in a power saving state and based on the actual residency time the processor may determine an optimal power saving state (P-state) for the processor. In response to the non-core domain entering a power saving state, an interrupt generator (IG) may generate a first interrupt and the device drivers or an operating system may use the first interrupt to start a timer (first value). In response to the non-core domain exiting the power saving state, the IG may generate a second interrupt and the device drivers or an operating system may use the second interrupt to stop the timer (final value). The power management unit may use the final and the first value to determine the actual residency time. | 07-05-2012 |

20140281457 | METHOD FOR BOOTING A HETEROGENEOUS SYSTEM AND PRESENTING A SYMMETRIC CORE VIEW - A heterogeneous processor architecture and a method of booting a heterogeneous processor is described. A processor according to one embodiment comprises: a set of large physical processor cores; a set of small physical processor cores having relatively lower performance processing capabilities and relatively lower power usage relative to the large physical processor cores; and a package unit, to enable a bootstrap processor. The bootstrap processor initializes the homogeneous physical processor cores, while the heterogeneous processor presents the appearance of a homogeneous processor to a system firmware interface. | 09-18-2014 |

20150292576 | DRY FRICTION CLUTCH WITH DAMPENING SYSTEM - A pneumatic dry friction clutch with a cone-shaped friction backing member and an intermediate member interlinked together with mating protrusions and recesses. The axial and circumferential degrees of freedom minimize or reduce noise and vibrations of the clutch, particularly any resonance. The clutch can be either an On-Off clutch or a two-speed clutch. | 10-15-2015 |
20150295487 | Overmolded Flux Ring - An overmolded steel flux ring member for an eddy-current fan drive assembly. The flux ring member includes a base member having a hub member, an annular outer ring member, and a plurality of connecting arm members. An overmolding material, such as aluminum, is overmolded on the annular outer ring member preferably in separate sections. Ventiliation openings in said base member allow air to flow past a magnet ring for cooling. | 10-15-2015 |

20110252337 | Messaging and Presence Protocol as a Configuration and Management Bus for Embedded Devices - Techniques are provided herein for establishing at a network management server a presence on a network. A presence associated with one or more managed devices on the network is detected. An instant messaging (IM) session is established with the one or more managed devices. The IM session forms a virtual chat room for performing a management function on the one or more managed devices, and IM messages are sent that are configured to perform the management function on the one or more managed devices. Techniques are also provided herein for establishing on a network an enriched presence by a network management server that is configured to perform a management function via a presence function of a messaging and presence protocol. | 10-13-2011 |
