The outstanding functions of this multi-fucntional wheelchair is that the hight of the seat could be adjusted at will. So that it may stretch users' operating space and make up users' physical handicap.It could alleviate the workload of paramedics as well. It is more advanced than previous products.This wheelchair could be driven by hand or electricity. Thus, the shortage of physical force of old and handicapped people could be solved. At the same time, users could still operate this wheelchair when batteries run out. Such design eliminate worries of users on a long-distance trip.In addition, a super big storage box on tail of wheelchair brings great convenience to users. backrest can be adjusted multi-anglely. Adjusted feet board increases cosiness. A small table of this wheelchair really brings extraordinary convenience when users want to read, write or do other activities.

本设计的多功能轮椅最突出的一个功能就是座位的高度可以根据使用者的需求随意进行调节，这样就可以大大扩展使用者的操作空间，补充了使用者在身体上的缺陷，也可以减轻照顾人员的工作负担，比起以前的产品有了较明显的改进；其他功能还有轮椅的手动电动两种驱动方式，这样可以解决老年人和残疾人在体力上存在的问题，同时在外出时遇上没电的情况也不至于显得无能无力，消除了使使用者在长途奔波时的顾虑；此外位于轮椅尾部的超大储物筐，给使用者携带物品带来了极大的方便，靠背的多角度调节，脚踏板的高度调节大大增加了使用者的使用舒适度，轮椅上小桌的设计给使用者读书，写字，进行其他活动带来了极大的方便。

With this technology the multimedia information can be displayed while it is being downloaded, so that the users do not have to waste their time when downloading, and there will be a redically reduced need in the system memeory capacity, and then the multicast technology of the streaming media transmit technology has more advantage, it has the functions which can transmit a stream for a group of client without any delay or broadcast storm. Therefore it can inprove the availability of the network system.

流媒体以边下载边播放的特点，不但除去了用户漫长的下载等待痛苦，而且极大地降低了对系统存储容量的需求，同时流媒体传输技术中的组播技术具有更大的优势，它能让媒体服务器同时向多个客户端发送连续数据流而不产生延时，而且又不会产生广播风暴，极大地提高了网络利用率。
