摘要： A supported catalyst is made by preparing a dispersion, contacting the dispersion with a substrate to produce a coating thereon, and firing and, if necessary, reducing to convert the dispersion to a catalytically active coating on the substrate. The catalyst may be useful in the catalysis of reactions for producing methane.The dispersion is made by co-hydrolysis to give an intimate mixture of hydrolysis products (e.g. hydroxides of Ni and Al) convertible by calcining and, if necessary, reduction to produce the catalytically active coating in the form of one or more catalytically active components (e.g. Ni) and one or more ceramic oxides (e.g. Al.sub.2 O.sub.3). Preferably, co-hydrolysis if effected by an agent such as urea which gives rise to no by-products in the coating.

摘要： An optical communications system using forward error correction (FEC) to correct errors in signals carried by the system. Optical signals on the system are dropped at nodes and converted to electrical signals by avalanche photodiodes (APDs) at the node receivers. An FEC chip operates on the electrical signal to correct errors. The error rate is used to control the APD bias voltage which affects signal noise and therefore error rate. The errors in a predetermined interval are counted and a determination made as to whether the error rate is rising with time. The bias voltage is derived from the value of a counter whose count is incremented each interval. If the error rate is rising, the counting direction is changed.
摘要翻译：一种使用前向纠错（FEC）来纠正由系统携带的信号中的错误的光通信系统。系统上的光信号在节点处丢弃，并在节点接收器处由雪崩光电二极管（APD）转换为电信号。 FEC芯片对电信号进行操作以校正错误。误差率用于控制影响信号噪声并因此影响误差率的APD偏置电压。对预定间隔中的错误进行计数，并确定错误率是否随时间而上升。偏置电压是从每个间隔增加计数器的值导出的。如果错误率上升，计数方向改变。

摘要： Systems and methods are described for detecting data traffic of a specific type, such as voice-over-IP traffic, on a network. A detector connected to the network is used to identify a set of data packets traveling across the network that conform to at least one signature describing data complying with a data transmission protocol. The detector is used to manipulate the set of data packets or create a record of data associated with the set of data packets. Such record can be analyzed or transferred to an external billing system to capture revenue for the transmission of the data.

摘要： A stabilized radiation source includes a distributed feedback laser, a back lens for coupling a portion of the output radiation into first and second optical paths, optical detectors for detecting radiation transmitted through the first and second paths, and for generating first and second signals indicative of radiation power, and a control circuit for controlling the laser in response to the signals for stabilizing. The first and second radiation paths are operable to provide substantially unfiltered and wavelength dependent filtered radiation transmission therethrough respectively to the detectors. Unfiltered radiation transmitted through the first path which is converted into the first signal is especially suitable for implementing laser output radiation power stabilization which is output radiation wavelength independent.
