摘要： A plurality of reference nodes that are attached to the network are correlated with geographic location. Communication latency between the reference nodes are used to approximate the location of a target node once the communication latency from one of the reference nodes to the target node is determined.
摘要翻译： 连接到网络的多个参考节点与地理位置相关联。 一旦参考节点之一到目标节点的通信延迟被确定，则参考节点之间的通信等待时间用于近似目标节点的位置。

摘要： A tuning system for use in radio frequency multi-signal receiving systems, e.g. a CATV converter, utilizes a closed feedback loop digital arrangement for channel selection (local oscillator frequency control) and channel fine tuning. The system may be implemented either via discrete hardware or through the use of microprocessor controlled apparatus.
