摘要： Instead of alternatively utilizing only one fabric or the other fabric of a redundant pair, both fabrics simultaneously transmit duplicate information, such that each packet forwarding module (PFM) receives the output of both fabrics simultaneously. In real time, an internal optics module (IOM) analyzes each information chunk coming out of a working zero switch fabric; simultaneously examines a parallel output of a working one duplicate switch fabric; and compares on a chunk-by-chunk basis the validity of each and every chunk from both switch fabrics. The IOM does this by examining forward error correction (FEC) check symbols encapsulated into each chunk. FEC check symbols allow correcting a predetermined number of bit errors within a chunk. If the chunk cannot be corrected, then the IOM provides indication to all PFMs downstream that the chunk is defective. Under such conditions, the PFMs select a chunk from the non-defective switch fabric. Under error-free normal conditions, however, the PFMs select a chunk arbitrarily from a default switch fabric. In this way, each chunk in real time is selected from a non-defective source and is thus guaranteed to be error free. Accordingly, if a switch fabric fails, no information chunks are lost anywhere in the system.
摘要翻译：代替替代地仅使用冗余对的一个结构或另一个结构，两个结构同时发送重复信息，使得每个分组转发模块（PFM）同时接收两个结构的输出。实时地，内部光学模块（IOM）分析从工作的零交换结构出来的每个信息块; 同时检查工作的一个重复交换矩阵的并行输出; 并且以逐块为基础比较来自两个交换结构的每个块的有效性。 IOM通过检查封装到每个块中的前向纠错（FEC）校验符号来实现。 FEC检查符号允许校正块内的预定数量的位错误。如果块不能被纠正，则IOM向下游的所有PFM提供指示该块是有缺陷的。在这种情况下，PFM从无缺陷的交换结构中选择一个块。然而，在无错误的正常条件下，PFM从默认的交换结构中任意选择一个块。以这种方式，从无缺陷源选择实时的每个块，并且因此被保证是无错误的。因此，如果交换机结构发生故障，系统中的任何地方都不会丢失任何信息块。

摘要： Power consumption that occurs in response to software errors may be reduced. In one example a system tracks a number of occurrences a first set of code causes a system to perform one or more reset actions, determines whether the number of occurrences exceeds a threshold, and selects a second set of code to execute in place of the first set of code, if the quantity exceeds the threshold.

摘要： Power management for a computing device is described based on idle thread code execution and other conditions. In one example, a controller is operated at a first power state. Then the controller is transitioned from the first power state to a second lower power state after it starts executing idle thread code. As an additional optional feature it may be determined whether any one or more of a plurality of conditions is true and the controller may be transitioned from the first power state to the second power state if one or more of the plurality of conditions is true.

摘要： A method for preparing a spiral wound filtration module is provided. The module has a central permeate carrier tube. The method includes winding at least one filtration leaf about the permeate carrier tube. The filtration leaf includes a first membrane sheet, a permeate carrier sheet, and a second membrane sheet. The winding step creates an end face extending radially outwardly from the permeate tube on each end thereof. After winding, the filtration module is maintained in a wound state. An adhesive is then supplied to each end face and a vacuum is applied through each of the permeate tube. While the vacuum is applied, the permeate tube and filtration leaf assembly are spun in a centrifuge until the adhesive has solidified. After spinning, each end face of the module is severed at a distance between the level of adhesive along the feed spacer screen and the level of adhesive along the permeate carrier sheet.
