  • Patent number: 8117660
    Abstract: A cross-module detection system and method for detecting and monitoring control flow transfers between software modules in a computer system. The system and method detect and monitor control flows entering and exiting the software modules. For a particular module, a checking model is extracted from the binary file of that module. In addition, a relaxed shadow stack is generated. If the module is an original module, meaning that the control flow originated from that module, then the checking model is used to check the validity of the control flow transfer. Otherwise, the relaxed shadow stack is used. An interception module is used to intercept and terminate invalid control flow transfers. If an invalid control flow transfer is detected, then the transfer is terminated. Otherwise, the control flow transfer is allowed to continue.

  • Publication number: 20110242001
    Abstract: A simplified touch screen system that can sense when an object is held in continuous direct or indirect contact with a transparent substrate of the touch screen system as well as determine a location (e.g., X, Y coordinates) of the object in relation to the transparent substrate. The touch screen system employs capacitance technology to sense whether the object is held in contact with the transparent substrate and acoustic sensing technology to determine a position of the object that is contacting the transparent substrate. The touch screen system requires a reduced number of shielding and isolation layers to be deposited upon the transparent substrate, partially because the touch screen system utilizes a bezel associated with an underlying display to provide shielding against electromagnetic radiation emitted by the display.
