摘要： A head-up display for vehicles, in which information from a display device is projected onto a transparent projection area, the display device has two transparent screens between which a liquid crystal substance and electrodes are arranged, polarized light penetrating through the liquid crystal substance, the liquid crystal substance rotating the polarized light penetrating through the liquid crystal substance in a plane of polarization in a manner dependent on the driving of the electrodes with a voltage. The polarized light emerging form the liquid crystal substance is not sent through a polarizer, but rather is polarized by the reflection at the transparent projection area or at one or more other reflectors which is or are arranged in the beam path of the polarized light between the liquid crystal substance and the transparent projection area.

摘要： A data stream between transcoders of a mobile wireless system is subdivided into a first data stream with samples for transmission and a second data stream with signal parameters for reconstruction of user data and/or for signaling. Both data streams are transmitted at the same time permitting an improvement in the quality of transmitted data, e.g. speech data in a GSM network in tandem operation between mobile subscribers.
摘要翻译：移动无线系统的代码转换器之间的数据流被细分为具有用于传输的样本的第一数据流和具有用于重建用户数据和/或信令的信号参数的第二数据流。同时传输两个数据流，从而允许提高发送数据的质量，例如，移动用户之间的串行操作的GSM网络中的语音数据。
