With the introduction of vehicle stability systems like ESP®, and passive safety systems like seat belts and airbags, driving safety has been improved and the number of road traffic fatalities and severe injuries have been significantly reduced in the last decades. Although these safety systems are state of the art for new passenger cars, in Germany the number of fatalities remains on a similar level in the latest years. At the same time, the need of the people for individual mobility is still increasing and this is resulting in higher traffic density, traffic complexity, and increasing stress for the drivers. Statistical data shows that the driver remains as an essential source for accidents. To further increase the driving safety and to relieve the driver of the complex task of vehicle guidance, today nearly all OEMs and suppliers are dealing with ideas for selfdriving vehicles or are engaged with highly automated driving (HAD) functionalities.

本标准涵盖配有一个或多个电池，电化学电容器或电化学电容器模块的便携式和移动式电源。如果配备电池，则电池应为铅酸或锂离子电池。电源组具有一个或多个输入和一个或多个输出。对于具有升压功能的电源组，这些电源组用于为耗尽的陆地车辆电池提供临时电源，最大额定值为24 V dc，以提供紧急启动电源。 本标准不包括UL 2056的《移动电源调查大纲》中涵盖的移动电源。

A high repetition rate Tm:Ho:LuLiF master-oscillator and polarization-maintaining (PM) Tm-doped fiber power-amplifier system is presented. A 11.3-kHz, 0.4-nm line width, 0.89-W Tm:Ho:LuLiF seed laser is developed. Using a two-stage PM Tm-doped fiber power amplifier system, 32.4-W output power is obtained with 0.4-nm line width at a central wavelength of 2058.5 nm, corresponding to 0.66-W seed laser. The laser spectrum and pulse profile are measured.

We report an all-fiber high power, single frequency large-mode area (LMA) linearly polarized ytterbiumdoped fiber amplifiers (YDFA) module, which is based on the master oscillator multi-stage power amplifiers (MOPA). The maximum output power is 43.8 W at a wavelength of 1064 nm when 60-W launched pump light is coupled, with high slope efficiency of 88%, polarization extinction rate (PER) >17.2 dB and nearly diffraction-limited beam quality (M2<1.1).
