  • Publication number: 20210267494
    Abstract: A joint movement analysis system, comprising: a plurality of actual markers positioned around a joint, wherein space positions of the actual markers track space movement of virtual marker points that are set at anatomical bony landmark positions of the joint; an optical tracking device that senses the space positions of the actual markers so as to obtain a space movement data of the actual markers; a data collection device that collects the space movement data of the actual markers and a relative space position data of the virtual marker points with respect to the actual markers; and a data analyzing device that obtains a space movement data of the virtual marker points from the space movement data of the actual markers, and simulates and analyzes a movement of the bony structure of the joint according to the space movement data of the virtual marker points.

  • Patent number: 8133951
    Abstract: A modified polyacrylonitrile fiber and its preparation process and use are disclosed. An animal hair micro powder is used as a modifier for polyacrylonitrile polymer. The weight percent of a monomer composition is as follows: acrylonitrile monomer 50.0-98.8%, initiator 0.1-0.4%, animal hair micro powder 1.0-50.0%. The preparation process of the modified polyacrylonitrile fiber comprises the following steps: 1. preparing the animal hair micro powder suspension, 2. preparing spinning dope of the modified polyacrylonitrile fiber, 3. preparing the modified polyacrylonitrile fiber. The fiber is suitable for making artificial synthetic hair product such as hairpieces, and resembles well natural human hair.
