Escaping once from spear-throwing Turkana in northern Kenya, he felt the chain come off, but managed to coast downhill to safety. He crossed China from north to south-in 2006, at 72-with just three brake-block changes, one jammed rear-brake cable and a change of tape on the handlebars.

在肯尼亚北路受到Turkana 人投矛袭击时，他感觉车链子掉了，但却成功地滑向了安全地带。2006年，72岁时他在中国从北骑到南，其间只换了三次闸，一个后煞车线和把手上的皮带。

Pass to computer control technology to the application and the research in the shaft hoist, we introduce that the new breeze well hoist computer control system to adopt the most advanced technique of PLC nowadays, by full-digital thyristor DC speed regulated system to constitute of parallel 12 pulse technology and magnetic fields to change toward technology, reform the traditional generator- electric motor machine set and relay control of hoist, by F- D machine set the unadvanced drive of wind reformation to become having the international advanced the horizontal full digital DC to drive the system.

通过对计算机控制技术在矿井提升机中的应用和研究，阐述了新风井提升机计算机控制系统采用了当今最先进的PLC技术、由全数字晶闸管直流驱动系统组成的并联十二脉动整流技术和磁场换向技术，来改造传统的发电机—电动机机组+继电器控制的提升机，从而使落后的F—D机组驱动的提升机改造成为具有国际先进水平的全数字直流驱动系统。

Compared with conventional PID controller, it can better avoid the qualitative spurious and unmodeled dynamics with the ability of reject disturbance.

结果表明基于节制闸启闭频率抑制的H控制器设计充分考虑到控制精度与模型误差抑制之间的关系，较传统PID控制具有更好的波动抑制能力。
