    • The present invention provides apparatus and methods for injection molding polymeric cannulae from liquid polymeric materials. The method includes injecting pressurized liquid polymer into a mold cavity and into an overflow and forming a conduit by forcing pressurized working fluid through the solidifying liquid polymer into the overflow. The invention provides a mold for fluid-assisted injection molding articles from polymeric materials, the mold comprising at least two parts defining a cavity having a conduit portion incorporating a needle portion; a channel for liquid polymer ingress; a channel for pressurized fluid ingress; and an overflow in communication with the conduit portion. The mold may incorporate a plurality of cavities. Preferably the volume of the overflow is equal to or greater than the volume of the conduit portion. Preferably the mold incorporates a separating means for separating the overflow from a cannula portion of an article formed in the mold.
    • 本发明提供了用于从液体聚合材料注塑聚合物套管的装置和方法。 该方法包括将加压的液体聚合物注入模腔并进入溢流口,并通过将加压的工作流体通过固化液体聚合物进入溢流口而形成导管。 本发明提供了一种用于由聚合物材料制备流体辅助注射成型制品的模具,该模具包括至少两个部分,其限定了具有引入针部分的导管部分的空腔; 液体聚合物入口通道; 用于加压流体入口的通道; 以及与导管部连通的溢流部。 模具可以并入多个空腔。 优选地,溢流器的体积等于或大于导管部分的体积。 优选地,模具包括分离装置,用于将溢流与在模具中形成的制品的套管部分分离。

    • A method of delivering an audio video asset is described. The method includes: receiving an order specifying an audio video asset to be delivered and a delivery destination for the audio video asset, wherein a delivery destination represents one or more physical delivery recipients; determining delivery paths representing different delivery technologies that could be used to deliver the audio video asset to the delivery destination; retrieving a set of path capacity timelines for the delivery paths, wherein path capacity timelines in the set of path capacity timelines each model a quantity of available capacity varying over time; processing the path capacity timelines to yield delivery path capacities; applying an allocation algorithm to the delivery path capacities to yield candidate delivery allocations, wherein candidate delivery allocations each includes one or more time periods during which one or more time periods a defined quantity of capacity can be allocated for delivery of the audio video asset; applying a cost function to the candidate delivery allocations to yield cost values, wherein the cost values each represent a cost of delivering the audio video asset according to the candidate delivery allocations; calculating scores for the candidate delivery allocations in dependence on a cost value for that candidate delivery allocation and one or more other objectives; selecting a candidate delivery allocation having a lowest score to yield a selected candidate delivery allocation; and delivering the audio video asset according to the selected candidate delivery allocation. Related apparatus and methods are also described.
    • 描述了传送音频视频资产的方法。 该方法包括:接收指定要传送的音频视频资产的订单和音频视频资产的传送目的地,其中传送目的地表示一个或多个物理传送接收者; 确定表示可以用于将音频视频资产传送到传送目的地的不同传送技术的传送路径; 检索所述传送路径的一组路径容量时间线,其中所述路径容量时间轴集合中的路径容量时间线每个模拟随时间变化的可用容量的数量; 处理路径容量时间线以产生传送路径容量; 将分配算法应用于递送路径容量以产生候选传递分配,其中候选传递分配每个包括一个或多个时间段,在该时间段期间,一个或多个时间段可以分配定义的容量数量用于传送音频视频资产; 将成本函数应用于所述候选交付分配以产生成本值,其中所述成本值每个代表根据所述候选交付分配递送所述音频视频资产的成本; 根据候选交付分配的成本值和一个或多个其他目标计算候选交付分配的分数; 选择具有最低分数的候选分配分配以产生选择的候选分配分配; 以及根据所选择的候选传递分配传送音频视频资产。 还描述了相关装置和方法。
