摘要： A method and apparatus is provided for connecting an optical source to a multimode optical fibre in a multimode optical fibre communications system. A single mode fibre length is provided such that optical radiation admitted from an optical source at one end of the single mode fibre length is provided to a multimode optical fibre at the other end of the single mode fibre length. This method and apparatus is used in a duplex patchcord for connecting an optical transceiver to a pair of installed multimode fibres. The second fibre in the patchcord is a multimode fibre for passing optical signals to the optical receiver of the transceiver.

摘要： In a method for encoding payload bits for transmission over communications link, data and control information are assembled into n-bit data words, where n is an even number and words for control information are constrained to have zero disparity (equal numbers of binary zero and one digits). The n-bit data words are then encoded into n+2-bit code words by adding a two-bit label; for words carrying control information the label has a value of 10. For other data words the disparity is evaluated; if it is zero, the label bits are 01; if the disparity is non-zero and opposite in sense to the running digital sum of the code words transmitted already, the label bits are 11; otherwise, the data word is inverted, and the label bits are 00.

摘要： Data are transmitted in blocks over a channel together with control signals for coordinating access to the channel. The control signals have the same values as some of the data blocks, these values being selected so that the control signals are spaced throughout the population of data block values and so that there is a greater Hamming distance between the control signal values than between the data signals. The control signals are transmitted between delimiter signals which differ from any of the data block signals, and are passed through a scrambling and encoding system in the same way as data signals, so that the spectrum of radiated electromagnetic emissions from the channel is not affected by the control signals.

摘要： An audio user interface is provided in which items are represented in an audio field by corresponding synthesized sound sources from where sounds related to the items appear to emanate. The interface is generated by apparatus that includes functionality for determining for each sound source, a rendering position at which the sound source is to be synthesized to sound in the audio field. To facilitate discrimination between the synthesized sound sources, the sound-source rendering positions are adjusted such that the audio field is dilated in a region of the audio field about a focus reference; this focus reference is, for example, the current direction of facing of the user or the position of an audio cursor in the audio field.

摘要： Codeword synchronization and scrambler synchronization in a block-coded serial communications link are accomplished by (i) substituting a specific comma control codeword for a selected codeword value occurring in the output of a scrambler receiving an input data stream, and (ii) using selected polarity-independent bits of the block-coded scrambled bit stream to convey samples of the scrambler state. Inversion of received control codewords indicates polarity inversion somewhere along the link, enabling automatic polarity correction to be applied.

摘要： An audio system comprises an audio source terminal 11 and a audio playback terminal 13, connected to each another by a wireless data link 14. The source terminal 11 comprises a source computer 15, and a cellular modem 17. The playback terminal 13 comprises a playback computer 19 having an internal processor 23 and an audio processor 24. Connected to the processor 23 is a cellular modem 21, an audio transducer 25, and a user control 27. Data relating to audio components, representing different services, is stored at the source terminal 11 where it is spatially processed and transmitted to the playback terminal. At the same time, each individual audio component is transmitted at a lower bit-rate than the spatially processed data, to the audio source terminal 11, whereafter it is spatially processed. Although the low bit-rate transmission causes a loss of audio quality, the positional data remains unaffected. Accordingly, when played, the combination of a high quality signal with low three-dimensional audio positional accuracy, and a set of low quality signals with high three-dimensional audio positional accuracy, results in restoration of the human perception of three-dimensional position to the degraded three-dimensional audio signal.

摘要： Logical connections between nodes in a network can be established by the following steps: generation of an identifier by each group of logically connected nodes in the network; exchange of identifiers between physically connected groups of logically connected nodes; and establishment of logical connections between physically connected groups of logically connected nodes for which the exchanged identifiers differ. Repeatedly carried out, these steps can allow a network without logical loops to be built up from individual nodes.
摘要翻译：可以通过以下步骤来建立网络中的节点之间的逻辑连接：由网络中的每组逻辑连接的节点生成标识符; 逻辑连接节点的物理连接组之间的标识符交换; 以及逻辑连接的逻辑连接组之间的逻辑连接的建立，其中交换的标识符不同。重复执行，这些步骤可以允许从单个节点构建没有逻辑循环的网络。
