  • Patent number: 6151599
    Abstract: A test page including a statement invoking an executable periodically reloading the test page is placed on a Web server having a security plug-in to be tested. The test page may include multiple frames, each containing a reference requesting access to the same test page or each performing a different testing function. The test page may be placed in a protected directory, may include an attempt to access the contents of a file within a different protected directory, and may include attempts to access protected CGI executables or other programs or modules which may be run on the Web server. A remote browser is employed to attempt to access the test page using the userid and password employed to login to the browser. Successful or unsuccessful access to the test page verifies proper operation of the security plug-in.

  • Patent number: 6138224
    Abstract: Wavetables for a wavetable synthesizer are divided into nonpaged and paged segments. The nonpaged segments are page locked in system memory, so that the wavetable may beginning playing when referenced. The paged segments are paged into memory as needed, and may be paged out of memory when no longer required. The segmentation of the wavetable is determined based on the maximum data rate for the wavetable and a maximum paging delay for the system. Wavetable segmentation is automatically tuned by monitoring actual paging delays and, taking into account a margin for error, updating the value of the maximum paging delay used to determine the required size for a nonpaged wavetable segment. An aggressive margin for error may be employed where an alternative mechanism is provided for handling overruns of the nonpaged wavetable segments.

  • Patent number: 6131185
    Abstract: A method and system for debugging an object from a plurality of objects forming an application in an object oriented system utilizing a graphic user interface. A number of the objects forming the application may include one or more action slots with each action slot containing one or more action objects. The present invention stores each action object with an action slot in an activation object in response to an event generated by user utilizing the graphic user interface. The event is associated with an action slot. Data sent to each action object is stored in the activation object. The data is data required to recreate the event caused by the user. Each time an event is generated, an activation object is created. These activation objects may be debugged utilizing a debugger.
