Abstract: A method for determining how using a respiratory therapy system impacts sleep sessions of a user, includes receiving first activity information corresponding to actions of a user occurring prior to a use of the respiratory therapy system by the user. The first activity information includes activity information associated with use of a mobile device by the user prior to the use of the respiratory therapy system. The method also includes receiving second activity information corresponding to actions of the user occurring after the use of the respiratory therapy system. The second activity information includes activity information associated with use of the mobile device by the user after the use of the respiratory therapy system, as well as respiratory information generated by the respiratory therapy system during a sleep session of the user when using the respiratory therapy system.

Abstract: A project portfolio management system creating virtual interrelationships between projects. Aspects of the system include creating virtual relationships at the Work Breakdown Structure (“WBS”) level with appropriate offsets using interpretations of logic relationships in detailed project schedules using various calculation approaches. The system models the linkages between detailed project schedules in a virtual relationship usable in alternate scenario planning analysis at a summary or working level. The virtual relationships are accurate enough for high level planning by users (e.g., program managers and analysts) with limited familiarity of project details (e.g., which non-workdays are in which project calendars) and reduce the computation times when altering a project planning scenario. Using the virtual relationships allows scenarios to be quickly evaluated to gauge the effects of changing constraints before committing to recalculating the detailed schedules of a project.
