Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: A transform apparatus applied in an image processing system with an image capture module is disclosed. The transform apparatus comprises a geometry information detector, a parameter setup unit, a primitive assembly unit and a geometry processing circuit. The geometry information detector measures geometry information of the image capture module. The parameter setup unit calculates geometry parameters and determines whether to assert an enable signal according to the geometry information. The primitive assembly unit receives an original vertex list and the enable signal to generate a vertex/ID flow. The geometry processing circuit receives the geometry parameters and performs geometry transform operations over the vertex/ID flow in response to whether the first enable signal is asserted to generate a modified vertex list. The geometry information comprises at least one of a displacement and rotation angles of the image capture module.

Abstract: A vertex processing device applied in an image processing system having an image capture module is disclosed. The image capture module generates camera images. The vertex processing device comprises a coefficient interpolation unit and a coordinate modifying unit. The coefficient interpolation unit generates an interpolated warping coefficient for each camera image with respect to each vertex from a vertex list based on n number of warping coefficients and its original texture coordinates in each camera image. The coordinate modifying unit calculates modified texture coordinates in each camera image for each vertex according to the interpolated warping coefficient and its original texture coordinates in each camera image. The vertex list comprises vertices with data structures that define vertex mapping between the camera images and a panoramic image. The n number of warping coefficients correspond to n number of overlap regions in the panoramic image.
