摘要： An optical add/drop multiplexer (OADM) adapted to route optical signals having at least two different bit rates. The OADM has at least two sets of DWDM channels, e.g., with channels in a first set having a first bandwidth value suitable for the transmission of 10-Gb/s signals and channels in a second set having a second bandwidth value suitable for the transmission of 40-Gb/s signals. The first and second sets occupy two different spectral bands and the first set has two subsets of interleaved channels. In one embodiment, the OADM has first and second optical branches adapted to process optical signals corresponding to first and second groups of channels, respectively. The first group includes a first subset from the first set while the second group includes the second set and a second subset from the first set. Advantageously, OADMs of the invention may be used to create independent processing paths for different groups of channels. As a result, a communication system having those OADMs can be upgraded, e.g., to add a new 40-Gb/s service and/or to populate additional 10-Gb/s channels substantially without interrupting the 10-Gb/s service already in place.
摘要翻译：适于路由具有至少两个不同比特率的光信号的光分插复用器（OADM）。 OADM具有至少两组DWDM信道，例如，第一组中的信道具有适合于传输10Gb / s信号的第一带宽值，以及具有适合于传输的第二带宽值的第二组中的信道的40 Gb / s信号。第一组和第二组占用两个不同的频谱带，第一组具有两个交织信道子集。在一个实施例中，OADM具有分别适于处理对应于第一和第二组信道的光信号的第一和第二光分支。第一组包括来自第一组的第一子集，而第二组包括第二组，第二组包括第一组。有利地，本发明的OADM可以用于为不同的信道组创建独立的处理路径。因此，可以升级具有这些OADM的通信系统，例如，为了增加新的40Gb / s服务和/或基本上添加10Gb / s信道，而不会中断10Gb / s的服务地点。

摘要： This disclosure is directed to a system designed for automatic de-clogging a rain gutter and a downspout. The system (also referred to as a gutter dredger) comprises a motion device (motor) and a cleaning device. When it is raining, rain water can power the system to cause reciprocating motions of the cleaning device that can result in de-clogging of a gutter and a downspout that have the system installed. A debris removal device may be positioned in the downspout to remove big debris before it moves into the motor. The gutter dredger can be used for automatically de-clogging a gutter and downspout whenever it is raining.

摘要： Detector data representative of an intensity of light that impinges on a detector after being emitted from a light source and passing through a gas over a path length can be analyzed using a first analysis method to obtain a first calculation of an analyte concentration in the volume of gas and a second analysis method to obtain a second calculation of the analyte concentration. The second calculation can be promoted as the analyte concentration upon determining that the analyte concentration is out of a first target range for the first analysis method.
