  • Publication number: 20070274598
    Abstract: An incremental patch is generated as a set of delta files or sector-specific patches, intended to be applied incrementally to an old binary image. Each sector-sized patch takes into account changes to the binary image made by previous patches in the series, such that cyclic dependencies are eliminated. The sector-sized patches are generated by applying a binary difference algorithm to the then-current partially patched image, until each sector has a corresponding delta file. The order for patching sectors may be determined by selecting sectors for patching based on first overwriting those sectors making the least contribution of data to generation of the new binary image.

  • Publication number: 20070087783
    Abstract: Systems and methods for operating upon a mobile communications device. A system and method can be used with data operations with respect to the mobile communications device's memory, wherein the memory has sectors. Data structures are used with the data operations to determine whether a sector contains valid data or to locate a record's pointer in the memory. The data structures can be used for such operations as record creation, record movement, recovery, etc.

  • Publication number: 20060077100
    Abstract: Systems and methods for providing symbolic information about fields, methods, and/or classes for a target device. A system and method may be used where the runtime processing is split between a host system and a target system. At the target device a test program uses a symbol not defined on the target device. A query is sent from the target device to a symbolic information source. The symbolic information source then provides the target device with information about the undefined symbol. The target device uses the information from the symbolic information source to complete the test program.

  • Publication number: 20060053191
    Abstract: Systems and methods for encoding floating point numbers. A system can include encoding logic which encodes invalid floating point representations as valid data. Decoding logic can be used to recognize the invalid floating point representations and map can provide the invalid floating point representations to valid data values. The decoding logic then can provide the valid data values so that operations on the valid data values can be performed in accordance with instructions received from an associated program.

  • Publication number: 20060020932
    Abstract: In some embodiments of the present invention, files are generated from java files or class files or jar files. The generated files are directly linkable and interpretable by a Java Virtual Machine. The generated files may be stored in a directly addressable memory of a device. References between class files may appear in the generated files as hard offsets or symbolic references. The generated files may be grouped so that cross-references between generated files in the same group appear as hard offsets.

  • Publication number: 20050129235
    Abstract: A method and system for performing garbage collection involving sensitive information on a mobile device. Secure information is received at a mobile device over a wireless network. The sensitive information is extracted from the secure information. A software program operating on the mobile device uses an object to access the sensitive information. Secure garbage collection is performed upon the object after the object becomes unreachable.

  • Publication number: 20050076344
    Abstract: Scripting Language based applications can be limited in their ability to supply and execute sophisticated logic and complex processing. More traditional programming languages contain explicit function and/or procedure calls to implement more complex functionality, however, these languages use more complicated syntax and traditionally require mosophisticated programming knowledge to use. There are provided systems and methods for extending the capabilities of an application program for execution by a terminal. The application includes a script based workflow and non-executable content. One such method comprises loading the workflow for interpretation by a script interpreter, such that the workflow is configured for having a plurality of executable elements. This method also provides a global symbol structure for reference by the executable elements, the global symbol structure including addressing for coupling selected ones of the executable elements to corresponding external components.
