摘要： A data exchange system for use in a system that includes a plurality of redundant channels (12). A data exchange unit (30) is provided to process data, ensuring that consistent data are used by each of the channels. The data exchange unit votes the data so that an output is provided that is identical in non-faulty channels. The data exchange units communicate over an inter-channel net that includes a consistency port (160), which serves as a separate second fault containment region for each channel, enabling the data exchange system to be Byzantine resilient. If input data are provided by a single one of the redundant channels, the data are distributed to each of the data exchange units for all channels in the system using two rounds of communication. However, if nominally identical data are input to each of the data exchange units in the redundant channels, a single round of communication and a simple voting process are used to determine a consistent output for each channel. A multiplexer (112) is used to select the data source for distribution to the consistency ports of each of the data exchange units. A 16-bit voter circuit (130) in each data exchange unit votes on the data received by the data exchange unit from the consistency ports for all of the channels to determine the output that is used by each channel.
摘要翻译：一种用于包括多个冗余信道（12）的系统中的数据交换系统。提供数据交换单元（30）来处理数据，确保每个通道使用一致的数据。数据交换单元对数据进行投票，以便提供在非故障通道中相同的输出。数据交换单元通过信道间网络进行通信，所述信道间网络包括一致端口（160），其用作每个信道的单独的第二故障容纳区域，使数据交换系统成为拜占庭式的弹性。如果输入数据由冗余信道中的单个信道提供，则使用两轮通信将数据分配给系统中的所有信道的每个数据交换单元。然而，如果将名义上相同的数据输入到冗余信道中的每个数据交换单元，则使用单轮通信和简单投票过程来确定每个信道的一致的输出。多路复用器（112）用于选择数据源以分发给每个数据交换单元的一致端口。每个数据交换单元中的16位选举电路（130）对所有信道的一致性端口对数据交换单元接收的数据进行投票，以确定每个通道使用的输出。

摘要： An aircraft communications and item tracking system is described. The system includes an RFID reader and a communications device located at fixed locations within the aircraft, a plurality of passive RFID tags operable for association with items within the aircraft, and a distributed antenna system comprising a plurality of antenna units and a wireless distribution system. The wireless distribution system is communicatively coupled to an aircraft communications network. The antenna units are communicatively coupled to the wireless distribution system and disbursed about the aircraft such that the RFID tags within the aircraft may be activated by signals output by at least one of the antenna units. The RFID reader and communications device are communicatively coupled to the wireless distribution system. The distributed antenna system is operable for transmission and reception of signals associated with the RFID reader and RFID tags. The distributed antenna system is further operable for transmission and reception of signals associated with the communications device.
