Abstract:
A cursor controller with a handle which moves in X, Y directions has the handle cantilevered on a upper platform which slides on an intermediate platform in an X direction with the axis of the handle intersecting the effective center of X guide means. And then the intermediate platform slides on a Y guide on a lower fixed platform, all of the foregoing being captured by a top cover. The top cover has a slot through which the handle, which is cantilevered on a bracket fixed to the end of the top platform, extends. The controller can be mounted directly on a keyboard or with a specially shaped enclosure to be operated by one hand.
Abstract:
A subclassing mechanism for use in developing graphical block diagram models is described. A graphical class instance of a library graphical class that corresponds to a graphical subsystem block of one or more interconnected graphical blocks is constructed for use in a graphical block diagram model of a user. An interface for enabling changes to parameter values of at least one of the graphical blocks to be made by and accepted from the user is provided. The changes are applied to the graphical class instance to produce a graphical class instance that inherits structure from the library graphical class.
Abstract:
Text and graphics elements may be alpha blended in a way to reduce flicker when the text or graphics are display by a processor-based television receiver. The alpha values are used to intelligently smooth pixels adjacent the element to create television text and graphics.
Abstract:
Methods and systems for creating and rendering skins are described, whereby an XML data structure comprises multiple tag pairs, individual tag pairs being associated with and referencing information that can be utilized to render a skin.
Abstract:
A stylus for a portable apparatus is disclosed. The stylus is usable as a prop to support the portable apparatus to stand on a platform and comprises a main portion and a rotating portion. The main portion comprises a tip end and a pivot end, and at least one protruding rib is disposed on the pivot end. A positioning plate is disposed on one end of the rotating portion, and connects with the protruding rib. A bolt passes through the protruding rib and the positioning plate, so that the rotating portion could pivotably connect with the main portion. Furthermore, at least one positioning structure is formed on one end of the positioning plate. The cross-sectional shape of the positioning structure is an arc shape. The stylus further comprises an elastic component and a positioning ball. The elastic component presses the positioning ball in the positioning structure, so that the portable apparatus could stand on a table surface. In addition, at least one groove is disposed on the sidewalls of the stylus. An elastic tenon of the portable apparatus could cling to the grooves, so that the inclination of the portable apparatus could be adjusted on the table surface.
