    • According to an embodiment of the present invention, an apparatus for performing video conferencing is provided that includes an I-frame injector element operable to intercept I-frame requests from one or more end points and to attempt to service the I-frame requests such that at least a portion of the requests are prevented from propagating back to an originating sender. In more specific embodiments, when a receiver endpoint sends a fast video update (FVU) request upstream, it is intercepted by the I-frame injector element and rather than passing the FVU request to the sender the I-frame injector element replaces a next P-frame from the sender with an I-frame, whereby the I-frame is constructed so that when decoded, it matches the P-frame that it replaced. In still more detailed embodiments, the I-frame injector element operates in one of three modes that are associated with bandwidth parameters.
    • 根据本发明的实施例,提供了一种用于执行视频会议的装置,其包括I帧注入器元件,其可操作以截取来自一个或多个端点的I帧请求并尝试对I帧请求进行服务,使得 至少一部分请求被阻止传播回始发端。 在更具体的实施例中,当接收机端点在上游发送快速视频更新(FVU)请求时,它被I帧注入器元件拦截,而不是将FVU请求传递给发送器,I帧注入器元件替换下一个P - 帧从具有I帧的发送器发送,由此构造I帧,使得当被解码时,它与其所取代的P帧匹配。 在更详细的实施例中,I帧注入器元件以与带宽参数相关联的三种模式之一操作。

    • An improved balance shoe is described. There is a balance shoe housing, wherein there is a pivot member. The pivot member forces at least one side support member against the interior surfaces of a window jamb channel when said window is tilted. The pivot member comprises a base section having a top surface and a bottom surface, said top surface having at least one pivot member extending therefrom, the pivot member being adapted to force said support member against the interior surface of the window jamb as said pivot member is rotated due to the tilting of the window sash.
    • 描述了改进的平衡鞋。 存在平衡靴壳体,其中存在枢轴构件。 当所述窗口倾斜时,枢转构件迫使至少一个侧支撑构件抵靠窗口通道的内表面。 所述枢转构件包括具有顶表面和底表面的基部,所述顶表面具有从其延伸的至少一个枢转构件,所述枢转构件适于将所述支撑构件压靠在所述窗口边框的内表面上,作为所述枢转构件 由于窗扇的倾斜而旋转。
