Abstract: An automated model componentization feature systematically converts duplicate or otherwise amenable patterns in a model into references. Multiple references are simplified to one unit that contains the otherwise duplicated functionality. Duplicated or selected functionality is identified based on a number of arguments that may be user supplied. These arguments include the level of polymorphism (i.e., which of the sample times, dimensions, and data types can be propagated in) but also the maximum size of the patterns to look for to address the general trade-off of generating few partitions with many blocks or many partitions with few blocks and which modeling constructs are used (e.g., whether Go To/From connections such as in Simulink® are present). Model conversions can result in potentially disjoint partitions.

Abstract: The present invention allows a user to graphically define a hierarchy of user-defined, executable classes of graphical objects that can be implemented in a graphical model. The present invention supports the features of inheritance, abstraction and polymorphism. Further, descendant classes of graphical objects can graphically extend the behavior and/or structure of ancestor classes of graphical objects.

Abstract: Methods and systems for improving a logic circuit are described. By using a voltage reducer for connecting a power-supply to a virtual ground, the voltage reducer reduces the voltage supplied by the power-supply to the virtual ground during one phase of the clock, thereby increasing the speed and efficiency of the logic circuit.

Abstract: A visual display for an electronic device is partitioned into regions. Each of the regions is associated with a key on a keypad. One exemplary implementation is a 3×3 grid of regions corresponding to nine keys numbered 1-9 on a numbered keypad. A visual correspondence is provided for the user to associate choices illustrated in the regions with the numbered keys. The regions display visual information such as graphics and/or text to identify a selection option. The keys are associated with the regions such that when a key is selected the selection option associated with the region is chosen. In this fashion, a user may navigate through content, such as content from the Internet, to gain accesses to service, to obtain information and to purchase items.

Abstract: An error diffusion technique seeks to remove artifacts resulting from the diffusion of large errors. This technique removes artifacts resulting from instances where there is little difference between a source color and a target color but there is a large diffused error component. The error diffusion technique clips a combination vector resulting from the combination of a source color with the diffused error component so that the combination vector extends roughly one quarter of the width of a color gamut beyond the boundary of the color gamut. This helps to prevent ever-increasing error vectors and, thus, helps prevent certain artifacts in images that are output.
