20100318832 | HANG RECOVERY IN SOFTWARE APPLICATIONS - Various embodiments provide a guard mechanism that is configured to prevent transmission of synchronous function calls to hung application components. In at least some embodiments, the guard mechanism receives a synchronous function call that is intended for an application component. Before permitting the synchronous function call to be transmitted to the application component, the guard mechanism determines whether the component is hung. Responsive to determining that the component is not hung, the guard mechanism permits the synchronous function call to be transmitted to the component. If, however, the guard mechanism determines that the application component is hung, a hung component recovery process is initiated. | 12-16-2010 |

Before permitting the synchronous function call to be transmitted to the application component, the hang resistance application layer determines whether the application component is hung by transmitting a message other than the synchronous function call to the application component that requests that a response be received before transmission of the synchronous function call to the application component is permitted. Responsive to determining that the component is hung, a hung component recovery process is initiated. | 08-23-2012 |

20150121194 | WEB CONTENT NAVIGATION USING TAB SWITCHING - A Web application maintains a record of Web content that has been displayed by the Web application. The user can navigate to different previously displayed Web content by providing various user inputs, such as a swipe across a touchscreen. The Web application detects when a user input has a threshold likelihood of being a navigation input, such as when the user swipes at least a threshold amount across a touchscreen. When a user input has a threshold likelihood of being a navigation input, the Web application begins rendering in an empty tab the Web content that would be navigated to if the user input were a navigation input, the empty tab becoming a prerender tab. If the user continues and the user input results in a navigation input navigating to the Web content rendered in the prerender tab, then the Web application switches to displaying the prerender tab. | 04-30-2015 |
