The V2 diagram for the overall framework (in an enclosed  black box) comes from http://www.myurc.com/, authored by Zimmermann and Vanderheiden.  This diagram extends it by UniTherapy specific components. The discovery and control session between target and URC is connected by Target-URC Network.  Out of band, the lower blocks in line with the "direct link" are specific to UniTherapy in order to provide a high-speed connection for performance session; a Target Intelligent Agent will be used to optimize the Target functionalities based on user's performance data and context information such as loaded protocol; also, the User Accessibility Resources (top right) are supplemental resources needed by a URC to customize user interface design when using UniTherapy.
