Patent number: 8229167Abstract: The present invention discloses an optical tracking device and a positioning method thereof. The optical tracking device comprises several light-emitting units, several image tracking units, an image processing unit, an analysis unit, and a calculation unit. First, the light-emitting units are correspondingly disposed on a carrier in geometric distribution and provide light sources. Secondly, the image tracking units track the plurality of light sources and capture images. The images are subjected to image processing by the image processing unit to obtain light source images corresponding to the light sources from each image. Then the analysis unit analyzes the light source images to obtain positions and colors corresponding to the light-emitting units. Lastly, the calculation unit establishes three-dimensional coordinates corresponding to the light-emitting units based on the positions and colors and calculates the position of the carrier based on the three-dimensional coordinates.Type: GrantFiled: January 19, 2010Date of Patent: July 24, 2012Assignee: Chang-Gung UniversityInventors: Shih-Tseng Lee, Yau-Zen Chang, Chan-Peng Lo

Patent number: 8106941Abstract: The present invention discloses a stereoscopic display apparatus comprising a first and a second image displayer, an aspherical reflection mirror, a beamsplitter and a housing. The first and the second image displayer are used for projecting a first and a second image light respectively. The aspherical reflection mirror is used for refracting the image light and for changing a polarity of the image light. The beamsplitter, disposed between the image generator and the aspherical reflection mirror, is used for deflecting a proceeding route of the image light based on the polarity of the optical signal. The housing has at least one opening for an operator to inspect a first image and a second image through.Type: GrantFiled: June 13, 2008Date of Patent: January 31, 2012Assignee: Chang—Gung UniversityInventors: Shih Tseng Lee, Chieh-Tsai Wu, Wen-Chung Teng, Hsin-Liang Chen

Publication number: 20110093023Abstract: The present invention illustrates a method of manufacturing a surgical implant guide to increase the precision, safety and reliability of the surgery. First the present invention plans an invasive position for implanting an implant, and then, plans an invasive path for the implant to invade from the invasive position of an affected tissue, and finally, produces an implant guide based on the invasive position, the invasive path, and the shapes of the implant and the affected tissue. The surgical implant guide includes a coupling portion matching the shape the affected tissue, and a guiding portion matching the shape of the implant, the invasive position, and the invasive path. When the coupling portion is disposed on the affected tissue, the guiding portion is aligned with the invasive position, so that the implant is implanted in the affected tissue under guidance of the invasive path.Type: ApplicationFiled: February 8, 2010Publication date: April 21, 2011Applicant: CHANG-GUNG UNIVERSITYInventors: Shih-Tseng Lee, Chieh-Tsai Wu, Heng-Liang Liu, Ming-Yuan Tsai

Publication number: 20100042164Abstract: The invention provides an expansion screw set, a hollow nail and an interior nail. The expansion screw set is composed of the hollow nail and the interior nail. The hollow nail has a hollow structure. A first thread and a second thread are provided for the inside and the outside of the hollow nail. The interior nail has a third thread. The hollow nail could nail an object through the first thread. The third thread of the interior nail corresponds to the second thread of the hollow nail. Therefore, the interior nail can be fastened into the hollow structure after the interior nail is nailed into the hollow nail. Moreover, the hollow nail has a separation line which runs parallel to the penetration direction of the hollow structure. Alternatively, the hollow nail has a plurality of penetration holes which is vertical to the penetration direction of the hollow structure. After the interior nail is nailed into the hollow structure, the separation line can be stretched out through the interior nail.Type: ApplicationFiled: October 20, 2009Publication date: February 18, 2010Inventors: Shih-Tseng Lee, Jyi-Feng Chen, Chieh-Tsai Wu, Hsun-Hui Hsu, Nan-Chun Liu
