    • Embodiments of the invention provide a method, distributed antenna system, and components that generate a jitter reduced clock signal from a serial encoded binary data stream transmitted over a communication medium. The method comprises receiving a modulated signal that includes the encoded binary data stream and extracting the encoded binary data stream. The method further comprises generating a recovered clock signal that is phase locked to the encoded binary data stream, generating an error signal based on a difference between a phase of the encoded binary data stream and the recovered clock signal, and integrating the error signal to generate a signal to control a voltage controlled oscillator. The method further comprises generating a stable recovered clock signal and producing at least one output clock by scaling the stable recovered clock signal frequency.
    • 本发明的实施例提供一种方法,分布式天线系统以及从通过通信介质发送的串行编码二进制数据流产生抖动降低的时钟信号的组件。 该方法包括接收包含经编码的二进制数据流的调制信号并提取编码的二进制数据流。 该方法还包括:生成与编码的二进制数据流相位锁定的恢复时钟信号,根据编码的二进制数据流的相位与恢复的时钟信号之间的差产生误差信号,并积分误差信号以产生 控制压控振荡器的信号。 该方法还包括通过缩放稳定的恢复时钟信号频率来产生稳定的恢复时钟信号并产生至少一个输出时钟。

    • A method comprising the steps of: providing a database server having a database comprising real-time data related a warehouse object, the real-time data including data regarding the location of the warehouse object and data regarding the time and date the warehouse object became resident at the location, the real-time data populated in the database by warehouse management software; providing at least one rule related to when a condition of location for the warehouse object must cease, each rule having an associated trigger based on a lead time required to avoid violation of the rule; receiving data related to the warehouse object at a computer; predicting a potential violation of the rule by comparing, on the computer, data regarding the time-date the warehouse object became resident at the location with the trigger; generating an alarm related to a potential violation of the rule; and providing an alarm to an operator.
    • 一种方法,包括以下步骤:提供具有数据库的数据库服务器,所述数据库包括与仓库对象相关的实时数据,所述实时数据包括关于所述仓库对象的位置的数据以及关于所述仓库对象成为居民的时间和日期的数据 在该位置,通过仓库管理软件填充数据库中的实时数据; 提供至少一个与仓库对象的位置的条件何时停止相关的规则,每个规则基于避免违反规则所需的提前时间具有相关联的触发; 在计算机上接收与仓库对象相关的数据; 通过在计算机上比较仓库对象在具有触发器的位置驻留的时间的数据来预测潜在违反规则的行为; 产生与潜在违反规则有关的警报; 并向操作者提供警报。
