Abstract: A system and method are provided for measuring the performance of a synthetic peer-managed content distribution network. Each node peers with one or more other nodes to share the content and facilitate its presentation to associated users. Each node collects session metadata for identifying the node's environment, presentation events regarding presentation of the content to users, and transfer events regarding the sharing of the content among peers. The nodes report their data toward a central entity that feeds the different types of data through different ETL pipelines to obtain the performance measurements. For example, the session metadata may allow the reach of a content item to be determined, the presentation events may be used to determine the quality of experience with the content item for users, and the transfer events may be used to determine how much external bandwidth the network conserved and/or how efficiently the nodes shared the content.

Abstract: A body mount assembly for reducing vibration between a vehicle body and a frame. The body mount includes a hydraulic radial bushing including an inner sleeve and an outer sleeve coaxial with the inner sleeve and having a hydraulic damping system disposed between the inner sleeve and the outer sleeve. A bottom retainer is positioned below a first end of the hydraulic radial bushing. An upper retainer is positioned above a second end of the hydraulic radial bushing. A flange bracket includes an axial sleeve portion coaxially surrounding the radial bushing and a plate portion extending from an end of the axial sleeve portion and including mounting apertures adapted for mounting the flange bracket to the vehicle frame. A vertical isolator is disposed between the upper retainer and the flange bracket.

Abstract: A center bearing support providing improved impact harshness, load capacity, and long term fatigue durability through the introduction of a tunable stopper element which allows greater control as the excitation levels of a supported shaft are increased, including an inner element installed on the inner periphery surface of an outer element fixed to a body side through an elastic body made of elastomer material and a center bearing or bushing installed on the inner peripheral surface of the inner element, wherein a stopper extending convergently is formed at the end part of the flexible main body of the elastic body, and a rib is formed between the stopper and the end part of the flexible main body at a specific phase interval, whereby, because a deformation force given by the contact of the stopper with the outer ring when an excessive displacement is input is absorbed by the displacement of the end part of the flexible main body, an abrupt rise of a spring constant can be suppressed.
