  • Method and system for distinguishing barcode scanner data entry from other forms of data entry
    Patent number: 8985460
    Abstract: Entry data from a data source is obtained, buffered, and analyzed using the one or more barcode scanner data entry differentiation criteria. Based, at least in part, on the analysis of the entry data using the one or more barcode scanner data entry differentiation criteria, a determination is made as to whether the data source is a barcode scanner or a non-barcode scanner data source. If a determination is made that the data source is probably a barcode scanner, then the entry data is categorized as barcode data and processed accordingly.

  • Bitmap image compressing
    Patent number: 7715642
    Abstract: An image (e.g., a sprite) having at least three textures is compressed by generating a map which represents boundaries separating regions in the image, and generating pointers that associate each of the regions with one of the textures. The resulting data structure may be used in decompressing the image.

  • Displaying and storing an image having transparent and non-transparent pixels
    Patent number: 6262746
    Abstract: An image is stored as data representing the values of non-transparent pixels, and stored instructions corresponding to some pixels, resulting in a data structure. The image may be displayed by executing two types of instructions. A first type of instruction includes a command to skip pixels in a destination image. A second type of instruction comprises a command to copy pixels from the source data to the destination image.

  • Method and apparatus for storing and rapidly displaying graphic data
    Patent number: 5926567
    Abstract: The present invention provides a method and apparatus for storing and rapidly yet recognizably displaying graphic data. Digital ink is sampled at a predetermined sampling frequency to derive a set of points representing the graphic data. This set of points is reduced in number in order to define an approximate yet recognizable form of the graphic data. The rapid rendering of the graphic data in its approximate form allows the user to glance through several or more fields of graphic data similar to the way in which one would flip through pages in a paper notebook. Reduction in the number of points also facilitates efficient storage of the graphic data.

  • Blitting of images using instructions
    Patent number: 5880739
    Abstract: An image is stored as data representing the values of non-transparent pixels, and stored instructions corresponding to some pixels, resulting in a data structure. The image may be displayed by executing two types of instructions. A first type of instruction includes a command to skip pixels in a destination image. A second type of instruction comprises a command to copy pixels from the source data to the destination image.
