Arthur D. Applegate has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • System for memory error checking in an executable
    Patent number: 6035426
    Abstract: The invention modifies an executing instance (target process) of an arbitrary computer program by replacing the heap manager in the target process. All functions in the process that manipulate dynamic memory are patched with replacement functions that implement improved heap management. The invention is applicable to any computer program that makes use of dynamic (heap) memory. In a second aspect of the invention, the improved heap implementation performs heap error checking in addition to managing heap storage. Alternative embodiments use the invention to improve performance (speed) using fast allocation algorithms, improve space efficiency of the program, or implement tracing of heap activity for debugging purposes.
    Type: Grant
