Abstract: A parent computer application interacts with one or more independently operating embedded child applications so as to provide an integrated seamless operating environment in which the embedded child applications are presented through the user interface of the parent application and may be controlled through the parent application. A computer operating system provides a user interface such that each installed computer application is allocated its own respective memory space by the operating system, and includes a library that is utilized for its operation, only one of the computer applications as an active application at any time. The system detects when one of the embedded child applications is the active application of the operating system, and in response changes a parent application attribute to ensure that a single integrated application window is displayed.

Abstract: A method for optimizing a test sequence to diagnose a failure mode of a device, such as a vehicle, is provided. At least one symptom of a fault of the device is received, and a plurality of taxonomies is generated. The taxonomies include a device component taxonomy, a fault taxonomy, and a diagnostic taxonomy, and each taxonomy has a plurality of nodes. At least one diagnostic test sequence, based on the symptom and the taxonomies, is generated, costs associated with the diagnostic test sequence are determined, and a cost optimal test sequence, based on the costs and the diagnostic test sequence, is generated.
