    • Method and apparatus for allocating bandwidth in a virtual channel connection. The number of fax calls expected in a trunk group is divided by the number of DS0s in the trunk group and multiplied by the number of DS0s in a subset of the trunk group. The result equals the number of fax call circuits for the subset. The number of voice call circuits for the subset equals the number of DS0s in the subset minus the number of fax call circuits for the subset. The number of fax call circuits is multiplied by the full DS0 bandwidth. The number of voice call circuits is multiplied by the bandwidth per voice call. The total bandwidth for the subset equals the bandwidth for fax calls plus the bandwidth for voice calls. These steps are repeated for other subsets entering an interface to determine the total bandwidth needed by the VCC.
    • 用于在虚拟通道连接中分配带宽的方法和装置。 中继线组中预期的传真呼叫数量除以中继线组中的DS0的数量,并乘以中继线群组的子集中的DS0的数量。 结果等于该子集的传真呼叫电路的数量。 该子集的语音通话电路数量等于该子集中的DS0的数量减去该子集的传真呼叫电路的数量。 传真呼叫电路的数量乘以完整的DS0带宽。 语音呼叫电路的数量乘以每个语音呼叫的带宽。 子集的总带宽等于传真呼叫的带宽加上语音呼叫的带宽。 对于进入接口的其他子集重复这些步骤,以确定VCC所需的总带宽。

    • Alignment systems and associated methods of using such systems to help aim an x-ray source at an x-ray detector are described in this application. The alignment systems can contain an electromagnetic radiation transmitter (or receiver) that is associated with the x-ray detector and an electromagnetic radiation receiver (or transmitter) that is associated with the x-ray source. Electromagnetic radiation produced by the electromagnetic radiation transmitter can be detected by the receiver and used to align the x-ray source and the x-ray detector in the x-ray device. In some configurations, the electromagnetic radiation transmitter contains a radio-frequency (RF) antenna (or antenna array) that is attached in a fixed position relative to the x-ray detector and the electromagnetic radiation receiver also contains an RF antenna (or antenna array) that is in a fixed position relative to the x-ray detector. Other embodiments are described.
    • 在本申请中描述了使用这种系统以帮助将X射线源瞄准X射线检测器的对准系统和相关方法。 对准系统可以包含与x射线检测器相关联的电磁辐射发射器(或接收器)和与x射线源相关联的电磁辐射接收器(或发射器)。 由电磁辐射发射器产生的电磁辐射可由接收器检测并用于将X射线源和x射线检测器对准在x射线装置中。 在一些配置中,电磁辐射发射器包含相对于X射线检测器固定的位置的射频(RF)天线(或天线阵列),并且电磁辐射接收器还包含RF天线(或天线阵列 ),其相对于x射线检测器处于固定位置。 描述其他实施例。
