摘要： A data terminal uses as its display device a liquid crystal display formed on one face of a thin silicon slice. The slice has formed in it the controlling circuitry, based on MOS devices, for the display and some at least of the associated circuitry. The control means also includes a microprocessor with its associated memories and interfaces.

摘要： In an optical fibre FDM system, the carriers are derived from the output of a high quality Master Oscillator, which output at frequency fo is applied to a Raman Nath modulator (RNM1) whose other input is a frequency f this gives as its outputs (assuming a five channel system) fo-2f, fo-f, fo, fo + f and fo + 2f. These are modulated by modulators (CM1 to CM5) with the signals to be sent, and the modulation results combined in a combiner (CB) for transmission to a remote station.
The oscillator output is also sent to the remote stations where it is frequency-shifted by a Bragg modulator (BM) and the resultant similarly dealt with by a Raman Nath device (RNM2) to give five frequencies which are used to demodulate the channels.
In an alternative the channel frequencies are switchable.摘要翻译： 在光纤FDM系统中，载波是从高质量主振荡器的输出导出的，其频率f0的输出被施加到拉曼Nath调制器（RNM1），其另一个输入是作为其输出的频率f0（假定 一个五通道系统）f0-2f，f0-f，f0，f0 + f和f0 + 2f。 这些由调制器（CM1，CM5）与要发送的信号进行调制，调制结果组合在组合器CB中以传输到远程站。 振荡器输出也被发送到远程站，在那里它被布拉格调制器（BM）频移，并且其结果类似地由拉曼Nath设备（RNM2）处理，以给出用于解调通道的五个频率。 在一个替代方案中，信道频率是可切换的。

摘要： An intelligence display arrangement suitable for an "electronic book" uses a smectic liquid crystal display device of the ambiently lit type. The pages of the "book", which are recorded on a relatively large capacity store, are transferred to an immediate access store which holds a small number of such pages. They are then transferred to the display device as needed by, and under the control of the user. Where the "electronic book" is for partially sighted users, it is possible to present a page, part of a page, a line, or part of a line on an enlarged scale.
