  • Integrated Fuzzing
    Publication number: 20150033079
    Abstract: Integrated fuzzing techniques are described. A fuzzing system may employ a container configured as a separate component that can host different target pages to implement fuzzing for an application. A hosted target file is loaded as a subcomponent of the container and parsed to recognize functionality of the application invoked by the file. In at least some embodiments, this involves building a document object model (DOM) for a browser page and determining DOM interfaces of a browser to call based on the page DOM. The container then operates to systematically invoke the recognized functionality to cause and detect failures. Additionally, the container may operate to perform iterative fuzzing with multiple test files in an automation mode. Log files may be created to describe the testing and enable both self-contained replaying of failures and coverage analysis for multiple test runs.

  • Utility knife avoiding accidental detachment of blade
    Patent number: 8935855
    Abstract: The invention discloses a utility knife preventing its blade from accidental detachment. Prior utility knives may lose constraint on the blade due to tilting of the retaining member when the blade receives external force from the blade holder pulling outward, causing the blade to detach accidentally from the blade holder. In the present invention, the line of the action force in the engagement area of blade and retaining member extends over the axis of axle pin where the retaining member is mounted, so that when the blade receives external force pulling it outward from the blade holder, a counterclockwise torque is formed to the retaining member to allow the retaining member constrain the blade more tightly and thus prevent the blade from accidental detachment.
