Abstract: A computer system which tends to give priority to user commands rather than to screen updates includes an event command queue (38) to which both user commands (from 14) and system screen update commands (from event controller 230) are applied. The information to be displayed is stored in a data container (226), and is accessed by a display processor (2280 in response to screen update commands from the output (38r) of the event queue (38). In order to allow user commands to have preference over system screen update commands, the event controller monitors the number of commands in the event queue, and does not issue a screen update command so long as the number of commands in the queue is greater than a predetermined or threshold number. Thus, a stream of user commands will preempt the generation of system screen updates, thereby giving preference to the user commands.

Abstract: An image storage and processing method constructs, clips, fills, and combines arbitrary 2-dimensional shapes in an advanced graphics system. The method supports processing of anti-aliased images by compressing the image into a novel AlphaRegion data structure. AlphaRegion encodes into the data structure both the partially transparent as well as the fully opaque alpha values of an image according to rectangular bands. A band is a contiguous series of scan lines that have the same pattern of alpha values in a single direction. AlphaRegion encoding results in a more compact representation than possible in a conventional bitmap, but without losing the anti-aliasing features. AlphaRegion can be constructed either by supersampling sub-scan lines of an image, from the scan lines of a gray-scale image, from an existing conventional 1-bit Region or alpha mask buffer, or directly from a scan-line conversion of a geometric shape. AlphaRegion stores image data into three arrays, yInfo, xInfo and alphaData.

Abstract: Improved methods for providing secure viewing of data in a computer system or computer network include blurring, or otherwise obscuring or reducing the legibility of, data in defined areas of the document to prevent nearby observers from viewing it. The defined areas can be determined by a variety of different factors, which can be set, for example, by the user and/or a system administrator. In one embodiment, an entire document, graphic image, or other type of displayed information is blurred, and only one or more relatively small user-defined viewing areas are legible to the user. In another embodiment, only sensitive areas of displayed information are blurred. The information-blurring effect can be implemented in different ways, such as through the particular software application, through the operating system, or through a custom or dedicated software module. Improved computers and computer networks for providing secure viewing of data are also described.

Abstract: A mechanism for processing graphical block diagram parameter expressions is presented. The mechanism achieves optimal implementation of block equations in the execution (run-time) environment by defining a mapping between user-defined block parameters and a run-time version of the parameters. The parameter processing mechanism also pools like, non-interfaced parameter expressions, allowing reuse of both uniform and non-uniform data across constant block parameters in the generated code and during model execution. The parameter processing mechanism further maintains an execution structure that maps the run-time parameter expressions containing interfaced variables to generated code for the block diagram so that the interfaced variables appear in the generated code. This mapping thus allows for interfacing to the interfaced variables in the generated code from any execution framework.

Abstract: An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a guide rail to guide the print head, a transport roller to feed the recording medium, and a cover to prevent the tube member from contacting the roller. As the print head reciprocates in a width direction of a recording medium, the tube protruding from a surface of the print head on an end side in a moving direction thereof bends or flexes when the print head moves together with a carriage. The bending of the tube in the rearward direction is restricted by a tube band contacting the transport roller and cover. The cover and guide rail form a plane vertical to a platen at front faces of the cover and the guide. When the bending or movement of the tube is blocked or restricted by the vertical plane to a tube bending direction, the tube is not raised.

Abstract: An ink jet printer includes an ink container supplying ink through a tube member to a separate print head to form an image. The ink jet printer also includes a supporting portion that supports the tube member. As the print head reciprocates in a width direction of a recording medium, the tube member flexes as the print head mounted on a carriage moves. The tube protruding from the print head is inclined at approximately 30 degrees with respect to a moving direction of the print head, toward the supporting portion. When the tube is pulled toward the supporting portion, resistance to the movement of the print head can be restricted. When the tube bends or curves between the supporting portion and the print head, the tube can be moved smoothly toward the supporting portion. Thus, when the print head reciprocates, the tube can flex smoothly and the resistance applied to the print head by the tube can be restricted, allowing proper ink supply to the print head.
