    • A system for bandwidth management and codec negotiation, according to one embodiment of the present invention comprises: a configuration storage module having supported codecs storage, codec lists and preferred site settings storage, and a call manager having an extension module, a trunk module, a location service engine, a codec manager, a bandwidth manager, and a media manager. The codec manager and the bandwidth manager used for negotiating a codec for a call between two endpoints. The present invention also includes a number of methods including a method for negotiating a codec for a call, a method for managing bandwidth for a call, a method for adding a description of a new codec supported by an endpoint, a method for adding an identifier of a supported codec to a codec list and a method for editing code site codec settings.
    • 根据本发明的一个实施例的用于带宽管理和编解码器协商的系统包括:具有支持的编解码器存储,编解码器列表和优选站点设置存储的配置存储模块,以及具有扩展模块,中继模块, 位置服务引擎,编解码器管理器,带宽管理器和媒体管理器。 编解码器管理器和带宽管理器用于协商两个端点之间的呼叫的编解码器。 本发明还包括许多方法,包括用于协商用于呼叫的编解码器的方法,用于管理呼叫的带宽的方法,用于添加由端点支持的新编解码器的描述的方法,用于添加标识符的方法 支持的编解码器到编解码器列表以及用于编辑代码站点编解码器设置的方法。

    • An expandable packer or anchor is disclosed. It features a gripping device integral to or mounted in a sleeve over the mandrel. Upon expansion, a sealing element engages an outer tubular and the gripping device, such as wickers on slips, preferably digs into the outer tubular. The expansion is preferably by pressure and can incorporate pressure intensifiers delivered by slick line or wire line. Release is accomplished by a release tool, which is delivered on slick line or wire line. It stretches the anchor or packer longitudinally, getting it to retract radially, for release. The release tool can be combined with packers or anchors that have a thin walled feature in the mandrel, to release by pulling the mandrel apart.
    • 公开了一种可膨胀封隔器或锚栓。 它具有与心轴上的套筒一体或安装在套筒上的夹持装置。 在膨胀时,密封元件与外管接合,并且夹持装置,例如滑盖上的木门,优选地挖入外管。 膨胀优选地是通过压力并且可以包括由光滑线或有线线递送的压力增强器。 释放是通过释放工具完成的,该释放工具在光滑线或有线线上传送。 纵向延伸锚或封隔器,让其径向收缩,释放。 释放工具可以与在心轴中具有薄壁特征的封隔器或锚固件组合,以通过将心轴分开来释放。
