摘要： A video segment including interactive links to information about an actor appearing in the segment may be prepared in an automatic or semi-automatic process. A computer may detect an actor's face appearing in a frame of digital video data by processing the video file with a facial detection algorithm. A user-selectable link may be generated and activated along a track of the face through multiple frames of the video data. The user-selectable link may include a data address for obtaining additional information about an actor identified with the face. The video data may be associated with the user-selectable link and stored in a computer memory. When later viewing the video segment via a media player, a user may select the link to obtain further information about the actor.

摘要： The present invention relates to improvement of the brittleness and cold flowability of a carbon dioxide-propylene oxide copolymer (PPC). The invention provides a blend comprising 50 to 98 parts by weight of a PPC; 2 to 50 parts by weight of a poly(butylenes succinate) (PBS) or poly(butylene succinate/adipate) (PBSA); 1 part by weight of a maleic anhydride, and 0.5 to 3.0 parts by weight of SiO2 and a method for producing the same. Compared with the pure PPC, the elongation rate at break of the blend of the invention increases by 3 to 15 times while the tensile strength maintains at 30 MPa or more. The blend of the PPC and PBSA can keep its dimension stably at 70° C., while the blend of the PPC and PBSA can keep its dimension stably at 55° C. No viscous flow occurs at these temperatures.

摘要： The invention relates to a polymeric end-capping reagent for carbon dioxide-epoxide copolymers and a method for producing the same. The polymeric end-capping reagents provided by the invention are maleic anhydride copolymers and maleic anhydride terpolymers. The polymeric end-capping reagent for carbon dioxide-propylene oxide copolymers of the invention is produced by a radical solution copolymerization method, and has a number average molecular weight of Mn=4-6×104, a distribution index of 1.5-3.0. By using the polymeric end-capping reagent provided by the invention, the disadvantages of the small molecular end-capping reagent like volatilization during melting and precipitation on the melt surface during cooling, can be effectively overcome, moreover, the initial thermal decomposition temperatures of the carbon dioxide-propylene oxide copolymers end-capped with the polymeric end-capping reagents increase by about 30° C., as compared with that of the carbon dioxide-propylene oxide copolymer end-capped with “small molecular” maleic anhydride.
