    • A wireless camera surveillance system for an aircraft is disclosed. The overhead video system comprises a wireless camera surveillance unit; and at least one mounting rail detachably coupled to the wireless camera surveillance unit. The mounting rail provides structural support and electrical power to the wireless camera surveillance unit. A system in one embodiment may use mounting rails that double as power rails supplying power to the wireless camera surveillance unit. Control is accomplished over a wireless link. The power rail control may be accomplished remotely via a standard or solid state relay. Normal rail power for the rail mounted wireless surveillance camera system may come from the utility bus.

    • An apparatus for connecting a laptop computer to a communications network for access by a seated user in a mobile platform. A cord reel assembly within the seat headrest includes a user interface retractable through the headrest and a user connector for connecting the laptop thereto. A connector to the network is situated below the seat. A seat interface extends from the cord reel assembly through the seat to the network connector. The apparatus provides an ethernet connection between the laptop and the network. The apparatus allows each seated passenger having a laptop to connect to an on-board communications network. The apparatus is for the most part hidden from view beneath the passenger seat.

    • A digital data processing system receives compressed variable length encoded digital data in the form of variable length codewords in contiguous variable speed Blocks of data. The boundary signals between adjacent codewords are determined and a demultiplexer sequentially sorts the serial digital data among a plurality of parallelly connected buffers for reducing the bit read speed of the buffers. A corresponding plurality of variable length decoders decodes the data from the buffers and outputs the data in parallel form to a multiplexer where it is reassembled into a serial expanded data stream. The incoming data includes selector information in fixed length headers that are separated, buffered and variable length decoded for controlling the demultiplexer. In one aspect of the invention, the data is sorted into substantially equal sized groups of integral codewords for equalizing the loading of the parallel buffers. In another aspect of the invention, the Block boundary marker signals are processed through much smaller auxiliary buffers using counters to keep track of the Block boundary marker signals for synchronization with the data flowing through the buffers.
    • 数字数据处理系统以连续的可变速度数据块中的可变长度码字的形式接收压缩的可变长度编码的数字数据。 确定相邻码字之间的边界信号,并且解复用器顺序地对多个并联连接的缓冲器中的串行数字数据进行排序,以减小缓冲器的位读取速度。 相应的多个可变长度解码器对来自缓冲器的数据进行解码,并且将并行形式的数据输出到多路复用器,并将其重新组合成串行扩展数据流。 输入数据包括固定长度报头中的选择器信息,其被分离,​​缓冲和可变长度解码用于控制解复用器。 在本发明的一个方面中,数据被分类成基本相等的大小的整数码字组,用于均衡并行缓冲器的负载。 在本发明的另一方面,块边界标记信号通过使用计数器的较小的辅助缓冲器来处理,以跟踪块边界标记信号,以与流过缓冲器的数据同步。
